1 systems, the container and tubing set are attached togcther 2 in a manner which protects only their interior portions from 3 contamination. Furthermore, such freedom from contamination l~
4 is not always achieved since the process of attaching the ~;
S ~ubing set to the containcr can itself introduce contamination C into the conrainer and tubing set. Even if the attachment is 7 made without contaminating their interiors, the exterior 8 portions of the container and tubing s~t are ~xposed to 9 contamination. Additionally, after attachment, the tubing set is generally extended and left to hang from the container.
11 This not only increascs the opportunities for contaminating 12 the interior of the tubing set, it also makes the container 13 and tubing set more difficult to manage and increases the 14 possibility of entangling the tubing se~ before its use.

I Descr ption Gf the Preferred Embodiment 3 Refcrring initially to Fig. 1, it is secn that the 4 prefrrrcd err,bodirnent of the invention includes a carton gcnerally designated 10. Also seen in Fig. 1 is a cap 12 which has a flip-
6 open vent 16 pivotally associated therewith. As seen in both
7 Fig. 1 and Fig. 4, the vcnt 16 is in the open position. As seen
8 in Fig. 2 and Fig. 3, the vent 16 is in the closed position. As
9 i3 best seen in Fig. 4, the vent 16 has an air passage 17 there-
10 through and a filter clement 18 operatively disposed in the air `
11 passage 17 near the outer end of vent 16. Also seen in Fig. 4
12 is an air passage 15 that is formed into cap 12 to provide for
13 air communication between reservoir 26 and the environment when
14 vent 16 is in the open position.
16 As can be best seen in Fig. 4, th~ carton 10 is 17 provided with a fill spout 20 which is defined by fill spout ' 18 flange 22. Fill spout flange 22 is ~ttached to carton 10 by any 19 manner well known in the pertinent art, .such as by radio frequency welding. In order to cooperate with cap 12, fill spouc flange 22 21 is formed with threads 24 which threadably engagc cap 12 in a 22 m~anrler that permlts the cap 12 to be eithcr operatively associated 23 with the cartcrl 10 or disengaged from the flange 22 and rcmoved 24 from carton 10 to provide an open passagewqy at fill spout 20 through which medical solutions can be poured into reservoir 26.
26 As shown in Fig. ~, the reservoir 26 is formed within carton 10.
28 Still referring to Fig. 4, lt is seen tha~ reservoir 29 26 is provldcd wlth an output port 28. An output fitmcnt 30 is opcrativcly associated with reservoir 26 by a eonnectlon 31 which provides for fluid communication through output port 28.

Preferably, the tùbing section 6 is made of polyvinyl chloride (P~C). A sleeve 34 of macrobcre 7 tùbing which may be made of polyvinyl chloride is slLdably 8 dis?osed over tubing section 32 in order to protect tubing 9 section 32 from crimping.
'' 11 The end o tubing section 32 opposite from the end 12 which was ~oined tc output fltment 30 is joined to the extension 13 38 of drip chamber top 36 by a means well known in the art, 14 such as by solvent bonding. As can be best seen with reference to Fig. 5, drip chamber top 36 is formed wiEh a cannula 54 and 16 is operatively associated with a valve 50. Drip chamber top 17 36 is also formed with an upper passage 42 and a lower passage 18 48. Valve 50 is iormed with ~ valve passage 44 and is rigidly .
19 attached to valve handle 40 so that upon rotation of valve handle 40 in the direction of arrow 52, t~.e valve passage 44.

4 The bell shaped portion of drip chamber 64 is attached to the engagement flange 56 by radio frequency welding or by any other 6 means well known in the art. A connector 66 is formed at the 7 end of drip chamber 64 opposite ~ro~ the end where drip chamber 8 64 is attached to engagement flange 56. Connector 66 i9 bonded 9 to tubing section 68 by means known in the art such as by solvent bonding. ~ \
12 Tubing section 68, which like tubing section 32 is 13 preferably made of po1yvinyl chloride, extends from ehe connector 14 66 of drip chamber 6~ and is solvent bonded to an input connector 70. The input connector 70 has a flui.d passageway tnot shown) 16 therethrough and is formed with an input collar 72. As can be 17 seen in Fig. 1, a ring 74 is formed onto input collar 72. ~lith 18 this str~cturc,ring 74 and input collar 72 can bc operatively 19 associatcd with a retainer slot (not shown) in a peristaltic pump (not shown). As shown in Fig. 1, for illustrative purposes 21 only, a portion of a pcristaltic pump has been indicated for 22 incorporation into the system by the repre3entative block 75.
23 Attached to input collar 72 on a side opposite from lnpu~
24 connector 70 is one end of a rubber tubing 76 which ls disposed in operative contact with A peristaltic roller asse~bly shown 26 generally at 77. Rubber tubing 76 is preferably made of a 27 matcrial, such as silicone rubber, which i9 well knowm in the 28 art as belng suited for operation in a perisealtic action. The 29 other end of rubber tubing 76 is attachcd to an output connector 80 havlng a fluid passagcw~y tnot shown) thcrethrough. Output ~_ J r ~ 3 ~ j .. ~i"'~ .i :
1 connector 80 is formed with an output collar 78 and output 2 collar 78 is held into the block 75, which represents a 3 peristaltic pump, by a retainer slot (not shown). At this 4 point it should be recognized that the ring 74 makes input '~ S collar 72 a differcnt size than the outpue collar 78. Both j 6 input collar 72 and output collar 78 are preferably madP with ¦ 7 polyethylene, and their difference in size as well as the 1 8 difference in size of their respective retainer slots (not ¦ 9 shown) allow for placement of the rubber tubLng 76 into the peristaltlc pump, represented by block i5, only in the direction 11 which results in fluid flow from the reservoir 26 and to the 12 patient during operation of the ~eristaltlc pump represented 13 by block 75.
Output connector 80 provides means for attachment 16 with ;ubing section 82. This connection is accompllshed by 17 any n~nner well known in the art, such as by solvent bonding.
18 l'ubing scctlon 82 is thcn connected to a patient's nasogastric 19 fitment (not shown) whlch ln turn is attached to the patient's nasogastric or 3ejuneostimy tube neither o which are shown in 21 dotail but w~ich arc shown in general configuration by the 22 reference character 81 in Fig. 1.

S nest 112. As formed into intcrdivider panel 94, the valve 6 nest 110 and valve handlc nest 114 are adapted to receive valve 7 handle 40 in a manncr which ensures that the valve passage 44, 8 and thus valve 50, are in the closed position as shown in Fig. 5.
9 As thus described, the drip chamber 64 and the assorted tubing sections o~ the prcscnt invention can be held within cnclosure 11 84 by a tear strip 86. Tear strip 86 is preferably an adhesive 12 coated gas permeable Tyvek paper, such as the type m~nufactured 13 by Oliver Products Company, which is heat sealed lnto position 14 as shown in Fig. 2 to provide a bacterial seal for the enclosure 84.
16 Fig. 3 shows that the tear strip 86 can be removed from 17 carton 10 to expose enclosure 84 by grabbing a corner of the tear 18 strip 86 and rotating it in a direction shown by thc arrow 88.
19 This brings tear strip 86 into an open posicion as shown in Fig. 3 for exposure of the contents held in enclosure 84.
22 Referring now to Fig. 6, lt can be appreciated that 23 the carton 10 is initially thermoformed from a single shcet of 24 a scmi-rigid transparent plastic, preferably from 25 ml PETg (polyethylene teripheilate, glycoal 1~odified3. As shown ln 26 ~ig. 6, the carton 10 comprises a front panel 90, ~ back panel 27 92, and an interdividcr panel 94. As will become apparerlt in 28 the furcher description of thc preferred cmbodiment, the front 29 panel 90 is thcrmoformcd intermediate che back panel 92 and intcrdivlder panel 94. Also formed into the c~rton 10 is a 31 I~
32 ~ I r~
~A3~
' 1 fold hinge 100 connecting interdivider panel 44 with front 2 panel 90 and folc! hinge 102 connecting front panel 90 with 3 back panel 92. During construction o the carton 10~ the 4 int:erdivider panel 94 is rotated about thc fold hinge 100 in 4 5 a direction indicated by the arrow 96 to bring interdivider 6 panel 94 into contact with the front panel 90, and weld line 7 106 is aligned with weld line 104. lt can be appreciated that 8 this connection forms the reservoir 26. In this position 9 interdivider panel 94 i9 attached to front panel 90 at the ~unc~ion or weld line 104 and weld line 106 in a manner well .
11 known in the art, such as by heat sealing or radio ~requency 12 welding.
14 The next step in construction of the carton 10 requires the rotation of back panel 92 about the fold hinge 16 102 in the direction of the arrow 98 as shown in Fig. 8. This 17 operaticn brings back panel 92 into contact with interdivider 18 panel 94 for dcfining the enclosure 84. With the carton 10 1 ¦
19 now intcrconnccted as shown in Fig. 8, the front panel 90, thc ~ ¦
back panel 92, and the intcrdividcr panel 94 are sealed together ' 21 along the weld line 108 as ~hown in Fig. 8 in any manner well 22 known in the art such as by heat sealing or radio frequcncy ~ ' 23 welding. ~ ¦
26 Opcration ~7 23 In opcration, the carton 10 i8 assembled with drip 29 chnmber 64 placcd into thc enclosurc 84 and fitted into drip chamber nest 112. Tl-c vnlvc handle 40 associated with drLp ~ ~, .. _. - : i ' -' .! ', 1 chamber 64 is also placed into enclosure 84 and is oriented 2 with rcspect to drip chamber 64 so as to fit into valve nest 3 110 and valve handle nest 114. As is seen in Fig. S wlth valve 4 handle 40 in the above described orientation, the valve 50 is closed, thus, valve passage 44 is not aligned with the upper 6 passage 42 and the lower passage 48, and t~ere is no fluid 7 comm~nication bet~een tubing section 32 and the drip chamber 8 64. Also placed into the enclosure 84 are tubing sectLons 32 9 and 63, rubber tubing 7i3, and tubing section 82. Tnese sections are placed into ~nclosure 84 in any su$table m~nner, such as by 11 coiling around the drip chamber 64. Tear strip 86 is heat 12 sealed onto carton 10 in such a msnner that the drip chamber 13 64 and the associated tubing sections are held in enclosurc 84 14 until carton 10 i5 ready to be placed into operation.
16 For gas sterilization of the rlgid medical solutions 17 carton 10, cap 12 is threadably engaged to fill spout flange 22 18 and vent 16 is rotated to the open posltion for air communlcation 19 between the reservoir 26 and the ambient atmosphere through filter element 18. Use of a gas per~eable papcr for tear strip 21 86 allows for the ga3 sterilization of carton 10 in the above 22 described orientation. Carton 10 can now be gas sterilized.
23 Af ter ~as sterilization the vent 16 ls rotated into the closed 24 posltion. It should also be understood that carton 10 can bc radiation sterillzed. In the latter csse there is no real 26 need for the vent 16 to be in the open posltion.
28 ~ue to the closed configuration of carton 10, filllng 29 of the reservoir 26 can be accomplished by removal o~ thc cap 12 from carton 10. Thls exposes fill ~pout 20 or th~ introductio , 1 of fluids into the rcservoir 26. After the medical solutions 2 or fluids have been introduccd into the reservoir 26, the cap 3 12 with vcnt 16 in thc closed position is agnin threadably 4 engagcd with fill spout flange 22. The carton 10 can now be s~ackcd or carried by use of a handle 116 which has been formed 6 into the cnrton 10. Carton 10 is ready for use in the 7 administration of medical solutions contained in reservoir 26.
9 For the adminis~ration of meciical solutions, the carton 10 is prepared by removing the tear strip 86 from the ; ,`
11 back of carton 10. This exposes the drip chamber 64 anci the 12 associated tubing sections. Carton 10 ean be suspended from 13 an IV pole (not shown) or any other convenient structure ~hich 14 is available for use. Rubber tubing 76 is no~ plaeed into operative association with a peristaltic pump, such as the 16 one represented in Fig. 1 by block 75. This is accomplished 17 by fitting the input collar 72 and output collar 78 into 18 retainer slots (not shown) on the peristaltic pump represen-19 ta~ively sho~m as block 75. Rubber tubing 76 is then operatively associatcd with the peristaltic roller assembly generally shown 21 as 77 in Fig. 1. Tubing section a2 is then joined with the 22 nasogastric fltment 81. Vent 16 is rotated to the open position 23 to provide air passage through the vent 16 and through the 24 filter ele~ent 18 disposed therein. Fluid passage from the reservoir 26 through tubing section 32 and through chamber 64 26 ls accomplislled by rotation of valve handle 40 in the direction 27 of arro~ 52 to align the valve passage 44 into the position 46 2a sho a in Flg. 5 and allow fluid communlcation between the upper, 29 pas.lge 42 and the lower passage 48. Drlp chamber 64 can be 3~ pinche~d by the operator to allow the oartial accumulation of . , ,' .' \.' "~,' ' '.
1 fluid within drip chamber 64. The peristaltic pu~p represented 2 by bloclc 75 can now be adjusted for the controlled pumping of 3 medical solutions through the rubber tubing section 76.
It must be understood that disclosure of the peristaltic 6 pump represcnted by block 75 was for illus~rative purposes only.
7 In an alternate cmbodiment of the present invention, there is no .. ;
8 necd for thè structure dcscribed herein for opera~ive association 9 with block 75. Indeed an embodiment wherein rubber tubing 76, inpu~ connector 70, input collar 72, ring 74, output collar 78 \ 11 and output connector 80 are omitted i3 ~1SO op~rational as a 12 gravity device. On the other hand, it must also be understood I I
13 that pumps other than a peristaltic pump can be used ~n ~ ¦
14 combination with the present invention. For example, an IV
pump as disclosed in U.S. Patent Number 3,985,133 may be used.
17 While the particular rigid medical solution con~ainer 18 and associated tubing set as herein shown and disclosed in 19 deeail is fully capable of obtaining the objects and providing thc advantagcs herein before stated, it is to be understood 21 that it is merely illustra~ive of the presently preferrcd 22 embodiment of the invention and tha~ no limi~a~ions are 23 intended to the details of construction or design herein 24 shown other than as defincd in the apended claims.
