PEN NEEDLE MAGAZINE DISPENSER
BACKGROUND OF l'~ ION
1. Field of the Irlvention The subject invention relates to a pen needle dispenser f()r a new pen needle 5 and, more particularly, to pen needle magazine dispenser that holds and dispenses sterile pen needles for medication delivery pens and that safely stores the needles a~er use.
2. De~cription of Related f~t Hypodermic syringes are used to deliver selected doses of medication to patients. The prior art hypodermic syringe includes a syringe barrel having opposed prox~mal and distal ends. A cylin~ 1 chamber wall extends between the ends and defines a fluid receiving chamber. I'he proximal end of the prior art syringe barrel is 2s subst~nfi~lly open and ~ceives a plunger in sliding fluid tight eng~gement. The distal end of the prior art syringe barrel includes a passage communicating with the charnber.
A needle c~nn~ A is mounted to the distal end of the prior art syringe barrel, such that the lumen of the needle c~nn.llq com.~ icates with the ~ssagc and the chamber of the syringe barrel. Movement of the plunger in a ~ ulllal direction draws fluid through the lumen of the needle r-qnn~ Lq and into the chamber. Mo~e..,e~ll of the plunger in a s ~),.,A-...zl-to~istal direction urges fluid from the chamber and ~v~h the lumen of the needle n-qnn~lq M.~ tion to be injectcd with the prior art h~,~)ode.mic syringe often is stored in a vial having a pie~dble elaslolne~;c seal. MÇdi~?tiotl in the prior art vial is 0 itCceA~I by piercing the elastomeric seal with the needle cqnn~ A selected dose of the m~~ on is drawn into the cl~l~r of the syringe banel by moving the l)lullg~r a select~ ~ in a ~lv~nal direction. The neodle c-qnn~lq is wiLhd.2l~l. from the vial, and the m~li~tion is injected into a patient by moving the l)lungel in a distal direction.
Some m~ie-qtion, such as insulin is self~ ~. The typical ~liqbetes pa~ient will r~quire injec~ionc of insulin several times during the course of thc day. The l~ui-~,d dose of insulin will va~y from patient to patient, and for each patient may vary during the course of the day and from day to day. 13ach diabetes patient will~establish a 20 regimen that is appropriate for his or her own medical condition and for his or her lifes~rle. The regimen typically inrl~.des some combination of a slow or medium acting insulin and a faster acting insulin. ~rh of the~e ,~;. ,Ylr may roquire the diabetes patient to p~.~iod~r lly self-ad-ioisb~r in~uUn in public bcations, such as places of empbyment or resh~Jri~rts~ The ~u-~d maoip~ation of the ;,t~.l prior art 2s l~nnic syringe and vial c n be incon~icnt and em~l< ssing in these public environments.
, CA 02244759 1998-08-12 Ms~icqtion delivery pens have been developed to f~q~cilitqt~ the self-a~lministr~qtiorl of n~e~in~tiorl A prior art ~-.e~ tion delivery pen is identified generally by the numeral 1 in Fig. 1. Pen 1 co.~t ;~ a cartridge with sufficients m~~ qtiQ~ for seve~ doses. The prior art cartridge has o~o~d ~ ,..al and distal ends. The distal end is closed by a pierceable and resealable rubber septum i.1. ~il;~l by the n~lmerql 2 in Fig. 1. Ihe plV~ulual end receives a stopper in sliding fluid-tight engagement. The prior art cartridge is ~ ose~l in an elongate pell-like body 4 with a pru~llal end (not showo) and an opposed distal end 6. The proximal end of the pen o body in-!.ldes a plunger for selectively driving the stopper of the cartridge in the dist l direction and a dose setting ...~ ni~m ~or d~e.nPi~ g the ~ tq-nce ~ Jugh which the plunger and stopper can move. Distal end 6 of pen body 4 inr hldes an arlay of threads 8 for threaded er~&q.~eme~-t with a pen needle assembly 90. Pen needle assembly 90 includes a needle cqnnlllq 91 with opposed pr~ al and distal points 92 and 93 and a Sthreaded mo~nting skirt 94 which surrounds the ~ i,nal tip 92. Mounting sl~t 94 is ?~'rly engageable with th~ds 8 on distal end 6 of pen body 4. A safety shield 95is releqc ~ly engag~yl over distal point 93 and portions of .~ou~l~;n~ skiIt 94 to p.
;dPnt~l needle s~cks.
20A person who must pen~i~qlly inject doses of medication will carry a medication delivery pen 1 and a supply of pcn needle assemblies 90. 13ach pen needle ly 90 has its needle caDnula 91 s fely and sterility sealed in its own shield 95, and is ~Sff~ immodiately pnor to . dmini~stering a dose of medication. Pen needle !qCs~ bly 90 then is mounted to distal end 6 of prior art pen 1. This mounting causes 2sp~u~ "al point 92 of needle ca~nula 91 to pierce rubber 2ieptum 2 of the c~l,i~ge, to place needle c~ 91 in communication with the medica~ion in pen 1. Pen 1 then is used to inject the selected dose of me~in~tion. After completing the injection, needle assembly 90 is separated from pen 1 and is discarded. Pen 1 may be used repeatedly m tnis "~armer until the medication is exhausted. Such prior art pens offer many conveniences and efficien~ies. However, the sto~age of unused needles and the final 5 ~ posql of used needles has ~ d problems. In particular, supplies of new needles often are loosely s~lt~.~d in the bottom of purses or b.; rcases, and used needles are often ~ pos~l of unsafely.
SI~DffARY OF T~IE INVE~ION
The subject invention rclates to a storing and dis~n~g a~ us for needle qC~hli~s used with hypodermic syringes and preferably a new type of pen needle that is decigJ-ffl to attach to an adaptor having conventional thr~ads that mate with threads 8 on medication delivery pens.
The pen needle ~iS~ of the present invention inclvdes a m~P7in~ cn~r having a cover rotatably moun~çd on a c4~ with a plurality of cavities, with each cavity ~ .n~ ~ to receive a new type of pen neodle assembly. The cover im~ des a slot that is rotated into aligoment with a cavity io tbe container that ~-;~;.~.c an 20 unusod pen oeedle. Whcn the slot is aligned with such a cavity, the user inscrts the adap~r on the ~.~ r delivery pen into the cavity and rotakec the pen to mount the unused pen needle on the medication delivery pen. After the inje~ion has been p~Çu.~ the usod pen needle is n~l~led to the cavity by ih~ g the used pen needle in the cavity and i~ the pen to detach the pen needle from the adaptor on25 the pen. The user then ~tes the cover until the slot in the cover provides access to the next cavity co~ , an~ ,r unused pen neodle to be used during the next injection.
An object of the present invention is to prevent the pen needle from being reused by having it covered in the pen needle mag~;ne ~ n~,r. In ~~ldition, onces the cover has been rotated to the next cavity, the pen needle mq~a7ine dis~.lse provides means to prevent the cover from l~in~ back to used pen nf~ll~s.
Another object of the present m~enLon is to provide a user with a-convenient way to carry, dispose of and keep track of their p~l~nal pen needle usage. The pen o needle mq&~7.in~ ~ii~n~er is decign~l to fit in the cap of the m~ic~ion delivery pen and contain a pred~ ed oumber of pen needles in ~ /e cavities, with each cavity being sealed by a n~....~.~l Iabel or ;,t~ilily n~ blane. The nun~bel~xl labels in~jc~~e how many unused pen aeedles remain in the pen needle m ~ .;nf dis~l~se~.
Another object of the present invention is to provide an adaptor that is threaded onto the distal end of conventi~l m~;c-~;on delivery pens so that a new type of pen needle can be used with such conventi~n~l medication delivcry pens. The new type of pen needle includes a base havmg threats on one end that drive the other end of the base into the adaptor to creatc a friction fit l~.o~ the adaptor and the~b se. The driving force is generated by u~ing thc adaptor to ro~tc the pen needle relative to its cavity and thereby unth~ad the pen needle from the cavity and force fit it in to the adaptor.
These and other ~ 4~ features and advantages of the present invention will 2s l~ 4 -'; apparent from the following de~iled d~ taken in conjunction with the accompanying dlva~ings.

~TAn4~) D~i(~R~ION
A pen needle ~2g"~ e Ai~ ~,r in accordance with the sub3ect invention is 25iC~;r~d ~en.o,r~lly by the numeral 10 in Pigs. 2, 3 and 4. Fig. 2 is an e~l~ded pe~ e view of a cap 3 on a ~ '91i~r delivery pen 1 an4d a pen needle ~ ~ag, ,;n~
dispenser 10, according to the present invention. Cap 3 includes a clip 5 and an open end 7 dimensioned to receive pen needle mqg,q.7.ine ~isrencp~r 10. Fig. 3 is a perspective view showing the aperation of inserting an adaptor S0 on distal end 6 of m~~ qtion delivery pen 1 into pen needle rlq~g~q7inlP dispenser 10 and the rc~ionql motion used to a~tach a pen needle as~llbl~l 100 to adaptor S0.
As shown in the ~ rl~ed p~ e view in Pig. 4, pen needle mqg,q.7in~
~ n.~ 10 inch~s a cover 20 . nd a co~ .Pr 30. Co-~ ~;~,. 30 includes a plulality of cavities 31 about the ci,cu,.lf~,~lce of container 30, with each cavity 31 lO ~limen~ioned to receive a pen needle assembly 100, desclibed further below. Each pen needle assembly 100 is originally sealed in its l~pauli~/e cavity 31 by a disc shaped label or sterility barrier 150 that is qt~~hed to an upper surface 32 of co.-t~;~ 30.
Label lS0 provides sterility for unused pen needle . ssemblies 100 co,l~lcd in each cavity 31 and a simple means for the user to identify whether the pen needle assemb;y 5 in a particular cavity has been used.
Pen needle ma~ ine dispenser 10 is initially loaded with a ~
uum~r of pen needle ~C~ bl ~s 100 in the plurality of cavities 31, with all of the cavities 31 being seabd by sterility baITier lS0 and having a number 1~1 t~ereoo20 corre~onding to each cavity 31. Each number 151 or other indicia on label 150indica~es to the user how maoy unused pen noedle ~ ;P~ 100 remain in pen needle ~ r 10. ~ ~hCl IS0 ;.~r~ s a centlal ~~ 152 through which cover 20 is t~ n~ on c~ ,r 30 al~d is scored at the location of each cavity 31 ~.ith~-lt, of course, arr~ing the integri~ of the seal to allow for controlled l)~h~g when 2s adaptor 50 on medication deliver~ pen 1 is pl.,ss~d ~ough label lS0 when loading pen needle ~mbly 100 on a~tor S0. The controlled breaking of the scored ar~ allows adaptor 50 on medication delivery pen I to be inserted through label 150 to mate with pen needle assembly l00 within cavity 31.
After pen needle In~7ine d;~ ~r 1, shown in Fig. 4, is loaded with new s needle assemblies 100 and fully assembled with cover 20 rotatably mounted on co,.~ e~ 30 and label 150 atta~hed to upper surface 32 over one of cavities 31, cover 20 is rotated with respect to c~ f,r 30 to move slot 21 over the first loaded cavity 31. As shown in Fig. 4, container 30 i~h des a central opening 37 and a pluIality of ratchet teeth 33 selectively spaced around an outer wall 35 of co~ h~el 30. C~
10 30 also inch~des a flange 34 that extends outwardly from outer wall 35 of co.~t~; ~e~ 30 below ratchet teeth 33 and an end of travel lock pin 36 that extends up from flange 34.
End of travel lock pin 36 works with a similar end of travel lock key 26 located on the underside of cover 20 to stop rotation of cover 20 on container 30 when all cavities have passed under slot 21.
Cover 20 inl~lu~le~ a centlal post 22 having an enlarged head 23. In r,d~liti~n,cover 20 inc~ des an outer lip 27 around its circumference that eYt~s down and over co ~ 30, when cover 20 is attached to C4~ f,~ 30. Outer lip 27 jnrl~d~ a ratchet tooth 25 ~ g tha~ in the dL~;on of container 30 tbat is dimensioned to ~o wo~k with the plurality of atchet teeth 33 on conlainer 30 to ~.,~nl cover 20 from ro~ng in a predetormined dilc~ion. Cover 20 is rota~bly at~ached to co ~t~ 30 after container 30 has been loaded with pen noedle assemblies 100 and label 150 has been attached to upper surfaoe 32 of cQ ~t~ 30 by inserting central post 22 intocentlal ~l~" ~ 37 in co~ L-r 30 until enlarged head 23 snaps to cent~al o~ 37.
2s When enlarged head 23 snaps inb centlal opening 37, cover 20 is a~ached to c4 ~A;-h,r 30 such tbat ratchet teeth 33 on ao.~ , 30 engage with ratchet twth 25 extcnding from cover 20 to only perrnit cover 20 to rotate in one direction, i e., a clockwise direction. Therefore, cover 20 is not permitted to rotate in the counter-clockwise direction or to move slot 21 back over cavities 31 con~i . n~ used pen needles 100.
s Of course, when cover 20 is ~tt~c-l~ to con~ r 30 it is ~)OI~t to locate end of travel lock key 26 on cover 20 ~1ia~ent to end of travel lock pin 36 on C~l~t'~ ,r 30, such that cover 20 can proceed with a full clockwise n~laLi~n on c~ 1a;l~el~ 30.
Thel~r~, when all cavities ha~te been ~ce~se~ using slot 21 on cover 20 and cover 20 has completed a complete clockwise rotation on container 30, end of travel lock key 26 o on cover 20 will again be . dj~ nt to end of travel lock pin 36 on cont~ e~ 30 but now will prevent fur~her rotation in the clockwise direction. In the current enl~o~lil..~ll, cover 20 can never be rotated in the counter-clockwise direction on collt~er 30 because of the above~escribed interaction of ratchet teeth 25 and 33.
As described above, cootainer 30 inclu~les a plurality of cavities 31 around itsci~;ull~e~ ce that are ~ PO~ to receive peo needle assemblies 100, mo~ clearly . .~
shown in Figs. S and 6 and fùrther d~il~d below. Fig. 5 shows a e.uss ~e~io.-~1 view of one of said plurality of cavities 31 and ~7ig. 6 more clearly shows adaptor S0.
As shown in Fig. S, each cavity 31 includes an open end 39 leading to an upper section 42 and a bottom section 41 leading to a closed end 44. Upper section 42 ;~l~Jd~ a ~ining ring 46 that mates with a matching ~ ring 55 on adaptor S0, when adaptor S0 is ms~ into cavily 31 to attach or detach pen needle ~ bly 100 to adaptor S0. Bottom section 41 has a smaller .l;c.~-~b~. than upper sectioo 42 with a shelf 43 formed where ~;on~ 41 and 42 meet. A set of threads 45 are located in the 2s bottom part of upper section 42 adjacent to shelf 43 and bottom section 41 is s;o~ed to receive a distal point 104 on pen needle assembly 100.
As shown in Figs. 5 and 6, pen needle assembly 100 includes a hub 102 having a triqngulqr shaped proximal end 109 and a distal end 107 having a set of threads 101 thereon ~ AC 0I1~1 to mate with the set of th~eads 45 within cavities 31. A needle s ~~qn~ llq 103 is mounted within hub 102 and in~h~de~ a distal point 104 and a plU~
point 105, wherein ~).vAi-"al point 105 extends from tn~n~lqr shaped ~ Ahllal end 109 and distal point 104 extends out of distal end 107 on hub 102. I~o~ al end 109 also in-~udP~ one or more splines 110 to improve the rotational operation of hub 102 within cavity 31 and increase the force-fft between hub 102 and adaptor 50. After a o plumlity of pen needle ~ssemhlies 100 have been loaded into pen needle m~ine .~r 10 and assembled, as shown in Fig. 4, pen needle m~7inP di~n3er 10 is ready for mounting in opening 7 of cap 3, as shown in Fig. 2.
As shown in Fig. 3, each newly de~ign~l pen needle assembly 100 within cavity 31 can only be removed and n~u~lt~d on a mçllicstion delive~y pen having an adaptor 50 accol~li,lg to the present invcntion. As shown in Pig. 5, ~ ~or 50 in~ 3es anopen p~al end 51 having a sct of threads 52 ~ ''A to mate with threads 8 on distal end 6 of conv~ntio~1 n~ia~~ion delivery pen 1. Adaptor 50 also ;~ hJ~eS aunique triangular shaped opening 53 in its dis~l end 54. After adaptor ~0 has been 20 threadod onto distal end 6 of pen 1, distal end 54 of adaptor S0 is used to remove pen needle $~ bly 100 from cavity 31 by ihl~,L~g triangular shaped p~ximal end 109 of ~eedle assembly 100 into triangular shaped opcning 53 in adaptor 50. When hiqn~ qr shaped p,~.al end 109 of n~dle ass~nbl~r 100 is ih~~~,~ into triangular shaped opc~ng 53 in adaptor 50, lu~t~on of "lrA;~ on delivery pen 1 causes pen needle 25 assembly 100 to rotate within cavity 31 and drive tnangular shaped p~,hl.al end 109 of needle ~ . bl~ 100 into a for~ed fit with triangular shaped Op~lg 53 in adaptor 50.
As pen 1 is rotated and needle assembly 100 is driven into adaptor 50, proximal point 105 of pen needle ~c~ ly 100 picrces rubber septum 2 of the cartridge in pen 1 s to place needle cq--nl~lv 103 in co~ cation with .--~di~ n contained within the cartridge in pen 1. The forced fit olsO holds ~ hl~l point 105 within rubber septum 2 and needle assembly 100 within adaptor 50 during the injection of medication from the cartridge in pen 1.
o After use, the used pen needle as~mbly 100 mounted on adaptor 50 on n eAicq~ion delivery pen 1 is reinserted into cavity 31 until retqinin~ rings 46 and 55 mate and the set of threads 101 on pen needle q~mbly 100 come into contact with the set of th~eads 45 within cavity 31. Medication delivery pen 1 is then rotated in the opposite direction to thread pen needle assembly 100 back into cavity 31 and pen 1 is then pulled out of container 30 as pen needle assembly 100 is pulled out a~or 50.
The user thcn rotates cover 20 until slot 21 is aligned with the next cOavity 31having an unused pen needle 100 that is still covered by labcl 150. As cover 20 is rotated ratchet tooth 25 tIavels over one set of ratchet teeth 33 on container~30, which 20 then p.~ cover 20 from rotating in the Oppb;.it~ d;,~li~n. Of course, an alternative to the uni di~ l cover shown in the d~a,.,n~s and dG~--;~d above would be a design that allows the user to rotate slot 21 back to previously used t~ es.
In that case, no ratchet mechanism would be needed but the other fea~res of the present invention could still be used in such a device. Howcver, as ~le~.il~d above 2s and shown in the dl~w~s, the alrrent dedgn allows the user to ~peatedly rotate cover 20 to each cavity 31 until all of the pen needle s~ liPs 100 have been used and the last cavity 31 has been encountered by slot 21 on cover 20. That last cavity could be left empty so that the user will know that all pen needle assemblies 100 have been used and thereby in~ e that pen needle m~g~7ine ~ per~,r 10 should now be ~lu~lly disposed of. In qd~ition~ by providing an empty cavity 31 with all f~ed cavities 31 s being fully enclosed behind cover 20, all the used pen needle assemblies lO0 and their ~,~o~ al points 105 would be protected from ~ridellt~l needle sticks, since cover 20 would no longer be able to rotate in either di~ction. As explained above, further rotation would be prevented by inte~ r)r ~n end of travel lock pin 36 on container 30 and end of travel lock key 26 on cover 20. If it is desired to use all the o cavities 31 in container 30 to hold pen needle assemblies 100, the al)p~dllls of the present invention can have a final rct~ti- r~l movement that is limted to a one-half (1/2) unit turn. In that case, slot 21 would be fin~llly positioned between the first cavity and the last cavity with all pen needle assemblies 100 being covered and csnt~ined within container 30 and cover 20 being prevented from rotation in either direction.

, CA 02244759 1998-08-12 Ms~icqtion delivery pens have been developed to f~q~cilitqt~ the self-a~lministr~qtiorl of n~e~in~tiorl A prior art ~-.e~ tion delivery pen is identified generally by the numeral 1 in Fig. 1. Pen 1 co.~t ;~ a cartridge with sufficients m~~ qtiQ~ for seve~ doses. The prior art cartridge has o~o~d ~ ,..al and distal ends. The distal end is closed by a pierceable and resealable rubber septum i.1. ~il;~l by the n~lmerql 2 in Fig. 1. Ihe plV~ulual end receives a stopper in sliding fluid-tight engagement. The prior art cartridge is ~ ose~l in an elongate pell-like body 4 with a pru~llal end (not showo) and an opposed distal end 6. The proximal end of the pen o body in-!.ldes a plunger for selectively driving the stopper of the cartridge in the dist l direction and a dose setting ...~ ni~m ~or d~e.nPi~ g the ~ tq-nce ~ Jugh which the plunger and stopper can move. Distal end 6 of pen body 4 inr hldes an arlay of threads 8 for threaded er~&q.~eme~-t with a pen needle assembly 90. Pen needle assembly 90 includes a needle cqnnlllq 91 with opposed pr~ al and distal points 92 and 93 and a Sthreaded mo~nting skirt 94 which surrounds the ~ i,nal tip 92. Mounting sl~t 94 is ?~'rly engageable with th~ds 8 on distal end 6 of pen body 4. A safety shield 95is releqc ~ly engag~yl over distal point 93 and portions of .~ou~l~;n~ skiIt 94 to p.
;dPnt~l needle s~cks.
20A person who must pen~i~qlly inject doses of medication will carry a medication delivery pen 1 and a supply of pcn needle assemblies 90. 13ach pen needle ly 90 has its needle caDnula 91 s fely and sterility sealed in its own shield 95, and is ~Sff~ immodiately pnor to . dmini~stering a dose of medication. Pen needle !qCs~ bly 90 then is mounted to distal end 6 of prior art pen 1. This mounting causes 2sp~u~ "al point 92 of needle ca~nula 91 to pierce rubber 2ieptum 2 of the c~l,i~ge, to place needle c~ 91 in communication with the medica~ion in pen 1. Pen 1 then is used to inject the selected dose of me~in~tion. After completing the injection, needle assembly 90 is separated from pen 1 and is discarded. Pen 1 may be used repeatedly m tnis "~armer until the medication is exhausted. Such prior art pens offer many conveniences and efficien~ies. However, the sto~age of unused needles and the final 5 ~ posql of used needles has ~ d problems. In particular, supplies of new needles often are loosely s~lt~.~d in the bottom of purses or b.; rcases, and used needles are often ~ pos~l of unsafely.
SI~DffARY OF T~IE INVE~ION
The subject invention rclates to a storing and dis~n~g a~ us for needle qC~hli~s used with hypodermic syringes and preferably a new type of pen needle that is decigJ-ffl to attach to an adaptor having conventional thr~ads that mate with threads 8 on medication delivery pens.
The pen needle ~iS~ of the present invention inclvdes a m~P7in~ cn~r having a cover rotatably moun~çd on a c4~ with a plurality of cavities, with each cavity ~ .n~ ~ to receive a new type of pen neodle assembly. The cover im~ des a slot that is rotated into aligoment with a cavity io tbe container that ~-;~;.~.c an 20 unusod pen oeedle. Whcn the slot is aligned with such a cavity, the user inscrts the adap~r on the ~.~ r delivery pen into the cavity and rotakec the pen to mount the unused pen needle on the medication delivery pen. After the inje~ion has been p~Çu.~ the usod pen needle is n~l~led to the cavity by ih~ g the used pen needle in the cavity and i~ the pen to detach the pen needle from the adaptor on25 the pen. The user then ~tes the cover until the slot in the cover provides access to the next cavity co~ , an~ ,r unused pen neodle to be used during the next injection.
An object of the present invention is to prevent the pen needle from being reused by having it covered in the pen needle mag~;ne ~ n~,r. In ~~ldition, onces the cover has been rotated to the next cavity, the pen needle mq~a7ine dis~.lse provides means to prevent the cover from l~in~ back to used pen nf~ll~s.
Another object of the present m~enLon is to provide a user with a-convenient way to carry, dispose of and keep track of their p~l~nal pen needle usage. The pen o needle mq&~7.in~ ~ii~n~er is decign~l to fit in the cap of the m~ic~ion delivery pen and contain a pred~ ed oumber of pen needles in ~ /e cavities, with each cavity being sealed by a n~....~.~l Iabel or ;,t~ilily n~ blane. The nun~bel~xl labels in~jc~~e how many unused pen aeedles remain in the pen needle m ~ .;nf dis~l~se~.
Another object of the present invention is to provide an adaptor that is threaded onto the distal end of conventi~l m~;c-~;on delivery pens so that a new type of pen needle can be used with such conventi~n~l medication delivcry pens. The new type of pen needle includes a base havmg threats on one end that drive the other end of the base into the adaptor to creatc a friction fit l~.o~ the adaptor and the~b se. The driving force is generated by u~ing thc adaptor to ro~tc the pen needle relative to its cavity and thereby unth~ad the pen needle from the cavity and force fit it in to the adaptor.
These and other ~ 4~ features and advantages of the present invention will 2s l~ 4 -'; apparent from the following de~iled d~ taken in conjunction with the accompanying dlva~ings.

~TAn4~) D~i(~R~ION
A pen needle ~2g"~ e Ai~ ~,r in accordance with the sub3ect invention is 25iC~;r~d ~en.o,r~lly by the numeral 10 in Pigs. 2, 3 and 4. Fig. 2 is an e~l~ded pe~ e view of a cap 3 on a ~ '91i~r delivery pen 1 an4d a pen needle ~ ~ag, ,;n~
dispenser 10, according to the present invention. Cap 3 includes a clip 5 and an open end 7 dimensioned to receive pen needle mqg,q.7.ine ~isrencp~r 10. Fig. 3 is a perspective view showing the aperation of inserting an adaptor S0 on distal end 6 of m~~ qtion delivery pen 1 into pen needle rlq~g~q7inlP dispenser 10 and the rc~ionql motion used to a~tach a pen needle as~llbl~l 100 to adaptor S0.
As shown in the ~ rl~ed p~ e view in Pig. 4, pen needle mqg,q.7in~
~ n.~ 10 inch~s a cover 20 . nd a co~ .Pr 30. Co-~ ~;~,. 30 includes a plulality of cavities 31 about the ci,cu,.lf~,~lce of container 30, with each cavity 31 lO ~limen~ioned to receive a pen needle assembly 100, desclibed further below. Each pen needle assembly 100 is originally sealed in its l~pauli~/e cavity 31 by a disc shaped label or sterility barrier 150 that is qt~~hed to an upper surface 32 of co.-t~;~ 30.
Label lS0 provides sterility for unused pen needle . ssemblies 100 co,l~lcd in each cavity 31 and a simple means for the user to identify whether the pen needle assemb;y 5 in a particular cavity has been used.
Pen needle ma~ ine dispenser 10 is initially loaded with a ~
uum~r of pen needle ~C~ bl ~s 100 in the plurality of cavities 31, with all of the cavities 31 being seabd by sterility baITier lS0 and having a number 1~1 t~ereoo20 corre~onding to each cavity 31. Each number 151 or other indicia on label 150indica~es to the user how maoy unused pen noedle ~ ;P~ 100 remain in pen needle ~ r 10. ~ ~hCl IS0 ;.~r~ s a centlal ~~ 152 through which cover 20 is t~ n~ on c~ ,r 30 al~d is scored at the location of each cavity 31 ~.ith~-lt, of course, arr~ing the integri~ of the seal to allow for controlled l)~h~g when 2s adaptor 50 on medication deliver~ pen 1 is pl.,ss~d ~ough label lS0 when loading pen needle ~mbly 100 on a~tor S0. The controlled breaking of the scored ar~ allows adaptor 50 on medication delivery pen I to be inserted through label 150 to mate with pen needle assembly l00 within cavity 31.
After pen needle In~7ine d;~ ~r 1, shown in Fig. 4, is loaded with new s needle assemblies 100 and fully assembled with cover 20 rotatably mounted on co,.~ e~ 30 and label 150 atta~hed to upper surface 32 over one of cavities 31, cover 20 is rotated with respect to c~ f,r 30 to move slot 21 over the first loaded cavity 31. As shown in Fig. 4, container 30 i~h des a central opening 37 and a pluIality of ratchet teeth 33 selectively spaced around an outer wall 35 of co~ h~el 30. C~
10 30 also inch~des a flange 34 that extends outwardly from outer wall 35 of co.~t~; ~e~ 30 below ratchet teeth 33 and an end of travel lock pin 36 that extends up from flange 34.
End of travel lock pin 36 works with a similar end of travel lock key 26 located on the underside of cover 20 to stop rotation of cover 20 on container 30 when all cavities have passed under slot 21.
Cover 20 inl~lu~le~ a centlal post 22 having an enlarged head 23. In r,d~liti~n,cover 20 inc~ des an outer lip 27 around its circumference that eYt~s down and over co ~ 30, when cover 20 is attached to C4~ f,~ 30. Outer lip 27 jnrl~d~ a ratchet tooth 25 ~ g tha~ in the dL~;on of container 30 tbat is dimensioned to ~o wo~k with the plurality of atchet teeth 33 on conlainer 30 to ~.,~nl cover 20 from ro~ng in a predetormined dilc~ion. Cover 20 is rota~bly at~ached to co ~t~ 30 after container 30 has been loaded with pen noedle assemblies 100 and label 150 has been attached to upper surfaoe 32 of cQ ~t~ 30 by inserting central post 22 intocentlal ~l~" ~ 37 in co~ L-r 30 until enlarged head 23 snaps to cent~al o~ 37.
2s When enlarged head 23 snaps inb centlal opening 37, cover 20 is a~ached to c4 ~A;-h,r 30 such tbat ratchet teeth 33 on ao.~ , 30 engage with ratchet twth 25 extcnding from cover 20 to only perrnit cover 20 to rotate in one direction, i e., a clockwise direction. Therefore, cover 20 is not permitted to rotate in the counter-clockwise direction or to move slot 21 back over cavities 31 con~i . n~ used pen needles 100.
s Of course, when cover 20 is ~tt~c-l~ to con~ r 30 it is ~)OI~t to locate end of travel lock key 26 on cover 20 ~1ia~ent to end of travel lock pin 36 on C~l~t'~ ,r 30, such that cover 20 can proceed with a full clockwise n~laLi~n on c~ 1a;l~el~ 30.
Thel~r~, when all cavities ha~te been ~ce~se~ using slot 21 on cover 20 and cover 20 has completed a complete clockwise rotation on container 30, end of travel lock key 26 o on cover 20 will again be . dj~ nt to end of travel lock pin 36 on cont~ e~ 30 but now will prevent fur~her rotation in the clockwise direction. In the current enl~o~lil..~ll, cover 20 can never be rotated in the counter-clockwise direction on collt~er 30 because of the above~escribed interaction of ratchet teeth 25 and 33.
As described above, cootainer 30 inclu~les a plurality of cavities 31 around itsci~;ull~e~ ce that are ~ PO~ to receive peo needle assemblies 100, mo~ clearly . .~
shown in Figs. S and 6 and fùrther d~il~d below. Fig. 5 shows a e.uss ~e~io.-~1 view of one of said plurality of cavities 31 and ~7ig. 6 more clearly shows adaptor S0.
As shown in Fig. S, each cavity 31 includes an open end 39 leading to an upper section 42 and a bottom section 41 leading to a closed end 44. Upper section 42 ;~l~Jd~ a ~ining ring 46 that mates with a matching ~ ring 55 on adaptor S0, when adaptor S0 is ms~ into cavily 31 to attach or detach pen needle ~ bly 100 to adaptor S0. Bottom section 41 has a smaller .l;c.~-~b~. than upper sectioo 42 with a shelf 43 formed where ~;on~ 41 and 42 meet. A set of threads 45 are located in the 2s bottom part of upper section 42 adjacent to shelf 43 and bottom section 41 is s;o~ed to receive a distal point 104 on pen needle assembly 100.
As shown in Figs. 5 and 6, pen needle assembly 100 includes a hub 102 having a triqngulqr shaped proximal end 109 and a distal end 107 having a set of threads 101 thereon ~ AC 0I1~1 to mate with the set of th~eads 45 within cavities 31. A needle s ~~qn~ llq 103 is mounted within hub 102 and in~h~de~ a distal point 104 and a plU~
point 105, wherein ~).vAi-"al point 105 extends from tn~n~lqr shaped ~ Ahllal end 109 and distal point 104 extends out of distal end 107 on hub 102. I~o~ al end 109 also in-~udP~ one or more splines 110 to improve the rotational operation of hub 102 within cavity 31 and increase the force-fft between hub 102 and adaptor 50. After a o plumlity of pen needle ~ssemhlies 100 have been loaded into pen needle m~ine .~r 10 and assembled, as shown in Fig. 4, pen needle m~7inP di~n3er 10 is ready for mounting in opening 7 of cap 3, as shown in Fig. 2.
As shown in Fig. 3, each newly de~ign~l pen needle assembly 100 within cavity 31 can only be removed and n~u~lt~d on a mçllicstion delive~y pen having an adaptor 50 accol~li,lg to the present invcntion. As shown in Pig. 5, ~ ~or 50 in~ 3es anopen p~al end 51 having a sct of threads 52 ~ ''A to mate with threads 8 on distal end 6 of conv~ntio~1 n~ia~~ion delivery pen 1. Adaptor 50 also ;~ hJ~eS aunique triangular shaped opening 53 in its dis~l end 54. After adaptor ~0 has been 20 threadod onto distal end 6 of pen 1, distal end 54 of adaptor S0 is used to remove pen needle $~ bly 100 from cavity 31 by ihl~,L~g triangular shaped p~ximal end 109 of ~eedle assembly 100 into triangular shaped opcning 53 in adaptor 50. When hiqn~ qr shaped p,~.al end 109 of n~dle ass~nbl~r 100 is ih~~~,~ into triangular shaped opc~ng 53 in adaptor 50, lu~t~on of "lrA;~ on delivery pen 1 causes pen needle 25 assembly 100 to rotate within cavity 31 and drive tnangular shaped p~,hl.al end 109 of needle ~ . bl~ 100 into a for~ed fit with triangular shaped Op~lg 53 in adaptor 50.
As pen 1 is rotated and needle assembly 100 is driven into adaptor 50, proximal point 105 of pen needle ~c~ ly 100 picrces rubber septum 2 of the cartridge in pen 1 s to place needle cq--nl~lv 103 in co~ cation with .--~di~ n contained within the cartridge in pen 1. The forced fit olsO holds ~ hl~l point 105 within rubber septum 2 and needle assembly 100 within adaptor 50 during the injection of medication from the cartridge in pen 1.
o After use, the used pen needle as~mbly 100 mounted on adaptor 50 on n eAicq~ion delivery pen 1 is reinserted into cavity 31 until retqinin~ rings 46 and 55 mate and the set of threads 101 on pen needle q~mbly 100 come into contact with the set of th~eads 45 within cavity 31. Medication delivery pen 1 is then rotated in the opposite direction to thread pen needle assembly 100 back into cavity 31 and pen 1 is then pulled out of container 30 as pen needle assembly 100 is pulled out a~or 50.
The user thcn rotates cover 20 until slot 21 is aligned with the next cOavity 31having an unused pen needle 100 that is still covered by labcl 150. As cover 20 is rotated ratchet tooth 25 tIavels over one set of ratchet teeth 33 on container~30, which 20 then p.~ cover 20 from rotating in the Oppb;.it~ d;,~li~n. Of course, an alternative to the uni di~ l cover shown in the d~a,.,n~s and dG~--;~d above would be a design that allows the user to rotate slot 21 back to previously used t~ es.
In that case, no ratchet mechanism would be needed but the other fea~res of the present invention could still be used in such a device. Howcver, as ~le~.il~d above 2s and shown in the dl~w~s, the alrrent dedgn allows the user to ~peatedly rotate cover 20 to each cavity 31 until all of the pen needle s~ liPs 100 have been used and the last cavity 31 has been encountered by slot 21 on cover 20. That last cavity could be left empty so that the user will know that all pen needle assemblies 100 have been used and thereby in~ e that pen needle m~g~7ine ~ per~,r 10 should now be ~lu~lly disposed of. In qd~ition~ by providing an empty cavity 31 with all f~ed cavities 31 s being fully enclosed behind cover 20, all the used pen needle assemblies lO0 and their ~,~o~ al points 105 would be protected from ~ridellt~l needle sticks, since cover 20 would no longer be able to rotate in either di~ction. As explained above, further rotation would be prevented by inte~ r)r ~n end of travel lock pin 36 on container 30 and end of travel lock key 26 on cover 20. If it is desired to use all the o cavities 31 in container 30 to hold pen needle assemblies 100, the al)p~dllls of the present invention can have a final rct~ti- r~l movement that is limted to a one-half (1/2) unit turn. In that case, slot 21 would be fin~llly positioned between the first cavity and the last cavity with all pen needle assemblies 100 being covered and csnt~ined within container 30 and cover 20 being prevented from rotation in either direction.
While the invention has been described with respect to a pr~f~ d emboAimsnt it is a~p~...ll that various G~ ~s can be made wi~out dgp~in~ from the soope of the invention as Aefin~d by the appende~ claims. For ~ nple, adaptor 50 can be integIally molded onto or pe~ ently attachod to distal end 6 of a medica~o~n delivery 20 pen 1 Iather than being a separ~e part.
