Description
216~7~0 W O 95t27435 PCT~US95/04516 Title of the Invention: SAFETY BLOOD COLLECTION TUBE ~IOLDER
This invention relates to blood collection devices and more particularly to a safety tube holder to be used for blood collection. The invention further relates to a tray to be used with the tube holder and its associated blood bags and ev~cll~te~l blood collection tubes.
BACKGROUND OF THE INVENTION
Blood from a patient is usually withdrawn by means of a blood collection needle and stored in a blood bag. Inside the blood bag is an anticoagulant to ensure that any blood collected will not coagulate. To collect blood, a phlebotomist would insert the needle to the vein of the patient so that blood 15 is drawn and passes via a ~ube into the blood bag. After the blood bag is filled, the tube is crimped. Dirrelen~ components such as red blood cells, plasma and platelets can be obtained from the blood for further testing or use.
The following problem exists for such conventional blood collection. To wit, 20 once the blood bag is filled, the phlebotomist needs to pull the needle out of the patient's vein. The only thing that the needle is molded to is a piece of elastomer that acts as a hub for the phlebotomist to hold onto. Thereafter, the phlebotomist has to thrust the needle into a blood collection tube, as for example a VACUTAINER tube, so as to remove samples from the blood 25 bag. To do this, the phlebotomist has to hold the VACUTAINER tube in one hand and thrust the needle through a rubber stopper that is fitted to the VACUTAINER tube with her other hand. The vacuum in the 216~70D -`
VACUTAINER tube causes the blood sample to be drawn, through the needle, from the blood bag. When the VACUTAINER tube is filled, the phlebotomist has to remove the now cont~min~te~l needle from the tube.
Ordinarily the phlebotomist has to repeat this process a number of time, as 5 a number of VACUTAINER tubes of blood samples are required for the different tests. Accordingly, if a phlebotomist were to take blood from the blood bag for three VACUTAINER tubes, she would have to thrust the needle through three rubber stoppers into three dirf~rent VACUTAINER
tubes. Thus, there are three chances that she could miss the rubber stopper 10 and instead have the needle (cont~min~tç-l after the first use) stab her handat the area between her thumb and wrist. Needless to say, with the current crop of blood-borne contagious diseases, such inadvertent exposure to cont~min~te~ blood needs to be prevented.
There is a product in the market which allows a phlebotomist to snap a 15 ~eedle thereinto, for piercing the rubber stopper of a VACUTAINER tube.
However, this available product does not protect a user from cont~min~ted blood that may be dripping from the end of the needle.
SUMMARY OF THE PRESENT INVENTION
To ensure that no cont~min~te~ blood is exposed to the environment, the 20 present invention tube holder has fitted thereinto an elastomeric tubular sheath having one open end and a closed yet pierceable end. The sheath is in alignment along the lon itu~in~l axis of the tube holder, with its open end positioned toward the end of the tube holder to which the needle (cannula) is to be inserted. To protect the user's hand, especially at the area between 25 the thumb and wrist, an integral protective shield large enough to protect the just mentioned area of the user's hand extends from the needle insertion end of the tube holder. There is also an internal circular flange within the tube holder to which the elastic tubular sheath is anchored, for example by means W O 95/27435 2 1 6 ~ 7 ~ O PCTrUS95/04516 -of a grommet. Extending toward the end of the protective shield are elastic clips for locking the needle, more precisely the hub of the needle, in place once the needle has been inserted to the tube holder and at least the tip portion of the c~nmll~ is enveloped by the tubular sheath.
S Thus, once a phlebotomist has withdrawn the blood collecting needle from the vein of a patient (after the apl)~ol)riate units of blood have been drawn into the blood bag to which the c~nmll~ is attached per tubing), instead of just holding the now blood soaked c~nmll~ and thereby exposing the same to the environment, the phlebotomist would insert the c~nn~ to the end of the 10 tube holder which has the protective shield, which protects the other hand ofthe phlebotomist as the c~nmll~ is being inserted to the tube holder. Upon the proper insertion, the c~nnlll~ becomes fixedly ret~in~ within the tube holder and enveloped by the elastic sheath. Accordingly, any cont~min~t~l blood that may be dripping from the c~nmll~ is cont~in~d within the sheath.
15 To obtain blood samples from the blood bag, a VACUTAINER tube is inserted to the other end of the tube holder. Tn~cmnch as the VACUTAINER
tube is sealed by an elastomer, for example a rubber stopper, when the VACUTAINER tube is inserted to the tube holder, the rubber stopper would slidably push against the sheath enveloping the c~nmll~ such that eventually 20 first the sheath, and then the rubber stopper, are pierced by the tip of the c~nm-l~ to effect a fluid communication path between the VACUTAINER
tube and the blood bag. Due to the vacuum in the VACUTAINER tube, blood is drawn thereinto. The VACUTAINER tube is withdrawn from the tube holder once it is full. Upon withdrawal of the VACUTAINER tube 25 from the tube holder, the elastic sheath returns to its original configuration to thereby again envelop the c~nm-l~. Additional samples of the blood for testing may be obtained by inserting additional VACUTAINER tubes to the tube holder.
wo ss/2743s 21~ ~ 7 ~ ~ PCT/US95/04516 An objective of the present invention is therefore to provide a tube holder that can protect the hand of a user when a blood collecting needle is to be inserted thereto.
It is another objective of the present invention to provide a tube holder that S can act as a valve for preventing the accidental exposure of cont~min~te~l blood to the user, or anyone else.
BRIEF DESCRIPIION OF THE DRAVVINGS
The above-mentioned objectives and advantages of the present invention will become more apparent and the invention will best be understood by reference 10 to the following description of embodirnents of the present invention taken in conjunction with the accompanying drawings, wherein:
Figure 1 is a semi-exposed side view of the tube holder of the instant invention;
Figure 2A is an exposed side view of a second embodiment of the instant 15 invention;
Figure 2B is a plan view of the tube holder, and more particularly the protective shield, of the Figure 2A embodiment of the present invention;
Figure 3 is a side view of the present invention showing another locking mech~ni~m for retaining a blood collecting needle in place;
20 Figure 4 is a plan view of a tray showing the different compartments therein for storing the various components of a blood collecting assembly; and ~1647~
-s Figure 5 shows a storage rack into which a plurality of VACUTAINER tubes may be stored for interaction with the tube holder of the present invention.
DETAILED DESCRIPIION OF THE INVENTION
With reference to Figure 1, the tube holder of the present invention is shown 5 to comprise a plastic barrel main body portion 2 that has a first open end (opening) 3 and a second open end 5. A flared lip extends circumferentially from the end of tube holder 2 at opening 3 to form a protective shield 20, or an escutcheon shield when viewed from Figure 2B about the opening at open end 3. Protective shield 20 is of sufficient dimension to coveredly protect 10 the portion of a user's hand extending from her thumb to forefinger and wrist.
Away from open end 3 within tube holder 2 is an internal circumferential flange 10 for accepting a gromrnet 16 to which an elastomeric tubular sheath 1`2 is molded. For the embodiment shown in Figure 1, extending from the 15 upper part of flange 10 are at least two semi-rigid snap extensions 6.
As further shown in Figure 1, a blood collection needle, as exemplified by c~nmll~ 13, is shown to be conn~cte-l to a conduit, or tube 8, which in turn is connected to and extends from a blood bag 30, shown in Figure 4.
Molded around the upper portion of c~nmll~ 13 is a housing or hub 26 20 having a key 14 extending longi~ lin~lly therealong. The horizontal dimension of hub 14 is such that it is somewhat larger than the distance separating the two tips 6a of snap extensions 6. Accordingly, when cannula 13 is inserted to opening 3, as hub 26 is guided along tube holder 2 by key 14 through a slot 15 (shown in Figure 2A), hub 26 would force snap 25 extensions 6 slightly apart, as its sides make contact with tips 6a of snap extensions 6. When fully inserted, as for example when bottom surface 26a of hub 26 makes contact with top surface 16a of grornmet 16, hub 26 is fully positioned within space 27 defined by snap extensions 6. Once the top portion of hub 26, particularly top surface 26c, passes tips 6a, snap extensions 6 would return to their original position to thereby fixedly retain hub 26 within space 27. Of course, inasmuch as c~nmll~ 13 is molded to hub 26, and since it has passed through grornmet 16 into elastomer sheath 12 as hub 26 is fixedly retained by extensions 6, it is completely enveloped by sheath 12. Thus, any cont~min~te~ blood that would have dripped from c~nmll~ 13 is collected within sheath 12, as sheath 12 acts as a septurn for preventing any fluid from passing therethrough.
To enable tube holder 2 to stand upright so that a user does not necessarily has to hold onto it, an optional circumferential flange 15 (shown in dotted line) extending from the edge of opening 5, may be integrated to tube holder 2.
Figures 2A-2B illustrate a second embodiment of the instant invention. Parts which function similarly or are the same as those described in Figure 1 are labelled the same.
With reference to Figure 2A, tube holder 2 now is shown to have an added portion 2a extending from the main tube portion of tube holder 2. Integrated to extension 2a is the escutcheon protective shield 20. Tnste~(l of internal flange 10 per the Figure 1 embodiment, an internal circumferential lip 40 is provided between the intersection of the main tube portion and extension 2a of tube holder 2. Instead of snap extensions 6 as shown in the Figure 1 embodiment, lip 40 has extending fingers 40a, which act to secure hub 26 of c~nmll~ 13 to tube holder 2. As should be readily apparent, the configuration of hub 26 is such that a groove 26d is provided at essentially the lowermost portion thereof to interact with fingers 40a for fixedly WO 95/27435 ~ 1 6 4 7 ~ ~ PCT/US95/04516 retaining hub 26, and therefore c~nn~ 14, in place, after the needle assembly has been inserted to tube holder 2.
Further shown in Figure 2A is an elastic tubular sheath 12, which is somewhat different from that of the Figure 1 embodiment. Specifically, 5 sheath 12, for the Figure 2 embodiment, is held in place by means of a circumferential hanger 42 welded to the upper interior portion of tube holder 2. The top portion of sheath 12 has a circular h~nging lip 44, which mates with the support fingers 42a of holder 42. To further secure sheath 12 within tube holder 2, and to further prevent the tip of c~nmll~ 14 from 10 piercing the upper sides of sheath 12, a plastic insert 46 is pressedly fixed to the upper portion of sheath 12.
In operation, for the Figure 2A embo~liment~ as canmll~ 14 is inserted to opening 3 and later through the opening of flange 40, key 14 of hub 26 is guided within slot 15 to thereby effect a smooth and steady insertion of c~nmll~ 14 to sheath 12. As shown, the tip of c~nmll~ 14, as well as a major portion thereof, is contained within sheath 12. A circumferential nub 48 internal to sheath 12 further provides the snug guidance for c~nnlll~ 14, as it is being inserted to sheath 12.
As was the case with the Figure 1 embodiment, once c~nmll~ 14 is properly 20 inserted to tube holder 2, it is fixedly retained thereto, by means of the interaction between finger 40a of flange 40 of tube holder 2 and groove 26d of hub 26. Thus, when a VACUTAINER tube 50 is inserted to opening 5 of tube holder 2, its elastomer sealer or rubber stopper 52, even though pushing up against the tip of c~nmll~ 14, would not dislodge the same from 25 its location within tube holder 2. More precisely, as VACUTAINER tube 50 is being inserted, the top portion of stopper 52 would push against the closed portion of sheath 12. As the VACUTAINER is further pushed 70~ 8 inwards within tube holder 2, sheath 12 is slidably pushed backwards until it is pierced by the tip of c~nmll~ 14. Thereafter, the tip of cannula 14 further pierces stopper 52 so that eventually it effects a fluid communication path between the inside of VACUTAINER tube 50 and tube 8. Once 5 VACUTAINER tube 50 is withdrawn from tube holder 2, sheath 12 would return to its original state so that any blood that may have dripped from canmll~ 14 would remain inside sheath 12.
Figure 2B is a plan view of the Figure 2A embodiment and shows shield 20 and the mating of hub 26 within extension 2a of tube holder. In particular, as shown, key 14 of hub 26 is being guided within slot 15 forlned within extension 2a of tube holder 2. Groove 26d is also shown, as are fingers 40a of flange 40.
Figure 3 shows a modification to the embodiments of Figures 1 and 2. In p`articular, it shows the retention of c~nmll~ 14 within sheath 12 by means of a semi-rigid friction ring 32 that is V-shaped. Portion 30 is formed within tube holder 2, with a cup 29 for receiving hub 26. For the Figure 3 embodirnent, c~nnlll~ 14 itself is shown to be fixedly retained within sheath 12. This retention can be by itself, or it can be used in conjunction with either the snap extensions 6 of the Figure 1 embodiment or the groove/fingers interaction of the Figure 2 embo~liment Figure 4 is a plan view of a tray 60 used in conjunction with tube holder 2.
As shown, tray 60 has a first compartment 62 for storing a plurality of blood bags 30. Further shown in tray 60 are additional compartments 64 and 66, each for storing a plurality of VACUTAINER tubes 50. Fitted to the center portion of tray 60, at an approl)liate chamber 68, is tube holder 2. Further shown pivotally coupled to tray 60 is a cutter adaptable to cut tube 8 and heat seal the same. To achieve sealing of tube 8, power is applied to cutter 70, W095/27435 216 I ~ ~ ~ PCT/US95/04516 ~ .
either by AC power or a battery (not shown). Thus, once the necess~ry samples are withdrawn from blood bag 30, a user would cut tube 8 and apply heat at the cut end to seal the same. Of course, the now used tube holder 2 with the cont~min~te~l c~nm-l~ 13 fixedly ret~in~ therein can be disposed of.
5 Any additional blood to be taken from blood bag 30 can be done by reopening the heat sealed tube and inserting a new c~nn~ thereto.
Figure 5 is an illustration of a retainer block 22 in which a number of VACUTAINER tubes 50 may be inserted to the respective holes 24. Block 22 thereby enables a user to quickly mate c~nn-ll~ 14 to a number of 10 VACUTAINER tubes by pushing tube holder 2 over those tubes. This easily enables a user to obtain the apl)fopliate number of samples of blood.
Tn~mllch as the present invention is subject to many variations, modifications and changes in detail, it is intended that all matter described throughout this s`pecification and shown in the accolllpallyii1g drawings be interpreted as 15 illustrative only and not in a limiting sense. Accordingly, it is intended that the invention be limited only be the spirit and scope of the hereto appended claims.
This invention relates to blood collection devices and more particularly to a safety tube holder to be used for blood collection. The invention further relates to a tray to be used with the tube holder and its associated blood bags and ev~cll~te~l blood collection tubes.

Molded around the upper portion of c~nmll~ 13 is a housing or hub 26 20 having a key 14 extending longi~ lin~lly therealong. The horizontal dimension of hub 14 is such that it is somewhat larger than the distance separating the two tips 6a of snap extensions 6. Accordingly, when cannula 13 is inserted to opening 3, as hub 26 is guided along tube holder 2 by key 14 through a slot 15 (shown in Figure 2A), hub 26 would force snap 25 extensions 6 slightly apart, as its sides make contact with tips 6a of snap extensions 6. When fully inserted, as for example when bottom surface 26a of hub 26 makes contact with top surface 16a of grornmet 16, hub 26 is fully positioned within space 27 defined by snap extensions 6. Once the top portion of hub 26, particularly top surface 26c, passes tips 6a, snap extensions 6 would return to their original position to thereby fixedly retain hub 26 within space 27. Of course, inasmuch as c~nmll~ 13 is molded to hub 26, and since it has passed through grornmet 16 into elastomer sheath 12 as hub 26 is fixedly retained by extensions 6, it is completely enveloped by sheath 12. Thus, any cont~min~te~ blood that would have dripped from c~nmll~ 13 is collected within sheath 12, as sheath 12 acts as a septurn for preventing any fluid from passing therethrough.
To enable tube holder 2 to stand upright so that a user does not necessarily has to hold onto it, an optional circumferential flange 15 (shown in dotted line) extending from the edge of opening 5, may be integrated to tube holder 2.
Figures 2A-2B illustrate a second embodiment of the instant invention. Parts which function similarly or are the same as those described in Figure 1 are labelled the same.
With reference to Figure 2A, tube holder 2 now is shown to have an added portion 2a extending from the main tube portion of tube holder 2. Integrated to extension 2a is the escutcheon protective shield 20. Tnste~(l of internal flange 10 per the Figure 1 embodiment, an internal circumferential lip 40 is provided between the intersection of the main tube portion and extension 2a of tube holder 2. Instead of snap extensions 6 as shown in the Figure 1 embodiment, lip 40 has extending fingers 40a, which act to secure hub 26 of c~nmll~ 13 to tube holder 2. As should be readily apparent, the configuration of hub 26 is such that a groove 26d is provided at essentially the lowermost portion thereof to interact with fingers 40a for fixedly WO 95/27435 ~ 1 6 4 7 ~ ~ PCT/US95/04516 retaining hub 26, and therefore c~nn~ 14, in place, after the needle assembly has been inserted to tube holder 2.
Further shown in Figure 2A is an elastic tubular sheath 12, which is somewhat different from that of the Figure 1 embodiment. Specifically, 5 sheath 12, for the Figure 2 embodiment, is held in place by means of a circumferential hanger 42 welded to the upper interior portion of tube holder 2. The top portion of sheath 12 has a circular h~nging lip 44, which mates with the support fingers 42a of holder 42. To further secure sheath 12 within tube holder 2, and to further prevent the tip of c~nmll~ 14 from 10 piercing the upper sides of sheath 12, a plastic insert 46 is pressedly fixed to the upper portion of sheath 12.
In operation, for the Figure 2A embo~liment~ as canmll~ 14 is inserted to opening 3 and later through the opening of flange 40, key 14 of hub 26 is guided within slot 15 to thereby effect a smooth and steady insertion of c~nmll~ 14 to sheath 12. As shown, the tip of c~nmll~ 14, as well as a major portion thereof, is contained within sheath 12. A circumferential nub 48 internal to sheath 12 further provides the snug guidance for c~nnlll~ 14, as it is being inserted to sheath 12.
As was the case with the Figure 1 embodiment, once c~nmll~ 14 is properly 20 inserted to tube holder 2, it is fixedly retained thereto, by means of the interaction between finger 40a of flange 40 of tube holder 2 and groove 26d of hub 26. Thus, when a VACUTAINER tube 50 is inserted to opening 5 of tube holder 2, its elastomer sealer or rubber stopper 52, even though pushing up against the tip of c~nmll~ 14, would not dislodge the same from 25 its location within tube holder 2. More precisely, as VACUTAINER tube 50 is being inserted, the top portion of stopper 52 would push against the closed portion of sheath 12. As the VACUTAINER is further pushed 70~ 8 inwards within tube holder 2, sheath 12 is slidably pushed backwards until it is pierced by the tip of c~nmll~ 14. Thereafter, the tip of cannula 14 further pierces stopper 52 so that eventually it effects a fluid communication path between the inside of VACUTAINER tube 50 and tube 8. Once 5 VACUTAINER tube 50 is withdrawn from tube holder 2, sheath 12 would return to its original state so that any blood that may have dripped from canmll~ 14 would remain inside sheath 12.
Figure 2B is a plan view of the Figure 2A embodiment and shows shield 20 and the mating of hub 26 within extension 2a of tube holder. In particular, as shown, key 14 of hub 26 is being guided within slot 15 forlned within extension 2a of tube holder 2. Groove 26d is also shown, as are fingers 40a of flange 40.
Figure 3 shows a modification to the embodiments of Figures 1 and 2. In p`articular, it shows the retention of c~nmll~ 14 within sheath 12 by means of a semi-rigid friction ring 32 that is V-shaped. Portion 30 is formed within tube holder 2, with a cup 29 for receiving hub 26. For the Figure 3 embodirnent, c~nnlll~ 14 itself is shown to be fixedly retained within sheath 12. This retention can be by itself, or it can be used in conjunction with either the snap extensions 6 of the Figure 1 embodiment or the groove/fingers interaction of the Figure 2 embo~liment Figure 4 is a plan view of a tray 60 used in conjunction with tube holder 2.
As shown, tray 60 has a first compartment 62 for storing a plurality of blood bags 30. Further shown in tray 60 are additional compartments 64 and 66, each for storing a plurality of VACUTAINER tubes 50. Fitted to the center portion of tray 60, at an approl)liate chamber 68, is tube holder 2. Further shown pivotally coupled to tray 60 is a cutter adaptable to cut tube 8 and heat seal the same. To achieve sealing of tube 8, power is applied to cutter 70, W095/27435 216 I ~ ~ ~ PCT/US95/04516 ~ .
either by AC power or a battery (not shown). Thus, once the necess~ry samples are withdrawn from blood bag 30, a user would cut tube 8 and apply heat at the cut end to seal the same. Of course, the now used tube holder 2 with the cont~min~te~l c~nm-l~ 13 fixedly ret~in~ therein can be disposed of.
5 Any additional blood to be taken from blood bag 30 can be done by reopening the heat sealed tube and inserting a new c~nn~ thereto.
Figure 5 is an illustration of a retainer block 22 in which a number of VACUTAINER tubes 50 may be inserted to the respective holes 24. Block 22 thereby enables a user to quickly mate c~nn-ll~ 14 to a number of 10 VACUTAINER tubes by pushing tube holder 2 over those tubes. This easily enables a user to obtain the apl)fopliate number of samples of blood.
Tn~mllch as the present invention is subject to many variations, modifications and changes in detail, it is intended that all matter described throughout this s`pecification and shown in the accolllpallyii1g drawings be interpreted as 15 illustrative only and not in a limiting sense. Accordingly, it is intended that the invention be limited only be the spirit and scope of the hereto appended claims.
