The pouch 1 may be ,' ! 12 AL 3 2 I
` 4 -, , i. manufactured from two sheets of the plastics material l which are joined together along their edges 3, 4 and a 'J, one end 5 for example by welding. Alternatively the two sheets may be former from the so-called 'afloat"
S tubing which is sealed at the one end 5. If required it the lay-flat tubing may also be welded along the edges t 3, 4. The one end of the pouch 1 is sealed in such a way that means are provided whereby the container can be suspended with the one end 5 uppermost in use. In `! lo the embodiment shown in Figure 1 a second weld line is provided Jo surround a flat portion 7 through which a I; hole 8 is punched so what, in use, the container may be , suspended by the hole 8.
The synthetic plastics material from which the pouch 1 is manufactured may be any material which is suitable for use in contact with the fluids used in l medical treatment (for example plasLicised Jo polyvinyl chloride, ethylene-vinyl acetate co polymers, j biaxially oriented polypropylene). Alternatively the 20 pouch may be manufactured from laminated or co-extruded medically acceptable plastics materials.
5' `~:
'I The member 2 is mounded for example by injection I mounding techniques from a material which is medically acceptable (for example plasticized polyvinyl chloride, 25 ethylene-vinyl acetate co-polymers or polypropylene co-polymers) and which is capable of being joined to the material of the pouch 1 in any suitable manner.
The member 2 comprises two ports 9, 10 separated by a web if. Planar flanges 12, 13 extend outwardly from Jo 3Q the ports 9, 10 in the same plane as the web if. The lot, flanges 12, 13 extend to the full width of the pouch 1.
The member 2 also comprises two removable tabs 14, 15 Jo which are connected to the web if and flanges 12, 13 by relatively thin sections 16, 17 of the member which are 35 cozily broken to enable the tabs to be removed from the Jo .
' - 5 ~L213~
member 2. To enable the tabs to be removed individually a further relatively thin section 18 is provided between the tabs 14, 15. Each tab 14, 15 has a frusto-conical passageway 19, 20 formed integrally ~here~Ji~h. The smaller diameter ends of these passageways 19, 20 are coaxial with the ports 9, 10 respectively. At the junction of the ports 9, 10 and the passageways I 20 there are sections of reduced thickness aye, aye to facilitate removal of the tabs 14, 15. The large diameter ends of the passageway are sealed by covers 21, 22. These covers are applied after filling the container as will be described hereinafter.
The ports 9, 10 will now be described in more detail. The port 9 as shim in Figure 4 is tubular and of circular cross-sectionO That part 23 of the bore of the port 9 which is directed into the container is of smaller diameter than that part I of the bore which communicates with the passageway 19. ennui the ccn~ainer is assembled prior to filling the bore of the port 9 is not obstructed but after filling a cup-shaped closure 25, the base of which forms a rupture able membrane, is inserted and sealed into the larger diameter part 24 of the bore to seal the colltainer as I will be described hereinafter. As the closure is inserted to its correct position it contacts the shoulder 26 formed jury the two parts 23, 24 of the burp meet.
The port 10 as shown in Figure 5 is tubular and of circular cross-section. The bore 27 is occluded by a membrane 28 which is integrally-moulded as the member 2 is formed. The membrane 28 is of such a thickness that it can be punctured by a needle and is preferably of a resilient material so that when the needle is removed the puncture hole tends to close to prevent egress of - 6 - ~2~2~
the contents of the container. The port 10 is intended Jo to be used to add additional materials such as ` medicaments Jo the contents of the container. To Jo prevent leakage of any liquid which does escape to ought $ 5 the puncture hole the portion of the bore 27 of the port 10 located outward of the membrane I receives a resilient plug 29 which is a friction fit in the bore and which is sufficiently resilient to seal any puncture hole made there through by a needle. The plus 10 29 may be cylindrical as shown in Figure 5 or it may by ,1 spherical prior to insertion and may be squashed after I! insertion to seal the port 10. So that the needle punctures the plug and membrane centrally a needle guide 30 is inserted outward of the plug 29. The 15 needle guide 30 is tubular and has a central bore of , sufficient diameter to enable a needle to pass easily 'I there through. The outermost ends 31 of the bore are ¦ flared to facilitate the correct insertion of the needle. Roth ends are flared to as to obviate the need 20 to orientate the needle guide before insertion. The needle guide may conveniently be made from a harder I' synthetic plastics material than the member 2.
Jo Polycarbonate and unplasticised polyvinyl chloride are , examples of suitable synthetic plastics materials from ; 25 which the needle guide 30 ma be fabricated. In an alternative embodiment (not shown the needle guide may be provided with a contoured outer surface so that the needle guide is positioned more 'securely within the `.~ port 10. For example the ends of the outer surface of I 30 the needle guide may be provided with shoulders.
I, . In an alternative embodiment (no shown! the port i 10 of the member 2 is identical Jo the port 9 as I described above and is sealed after filling by a } cup-shaped closure similar to that described above by I` 35 reference numeral 25. The plug 29 and needle guide 30 `;
. , !
are then inserted into the interior of the closure as described above.
The web 11~ and flanges 12, 13 may extend the full length of the ports 9, 10 as shown in Figure 2 or the innermost ends of the ports 9, 10 may extend into the , interior of the container as shown in Figure 3.
In a further embodiment illustrated in Figures 9 and 10 the member 2 carries two ports pa, boa which taper towards the interior of the bag as shown in Figure boa. In Figures 9, 10 aye and 11b the components which have already been described are identified by the same reference numerals as used herein before. In Figures and 10 the tabs 14 and 15 are joined at their central edges to a central 1 15 projection 36 by relatively thin sections aye and 18b Jo The provision of a central prniection 36 minimizes the risk that during the removal of one of the tabs, the integrity of the sterile seal funned by the other of the tabs is jeopardized. the embodiment of Figure 9 has apertures 37 in the tabs 14, 15 Jo facilitate the removal of the tabs. Similar apertures may be provided in the embodiments illustrated in Figures 2 and 3 as shown by the dotted lines in those Figures.
. -To further facilitate the removal of the tabs 14, lo the flanges 12, 13 may be provided with apertures to ; enable the user to obtain a firmer grip. Alternatively the outer surfaces of the flanges or the material forming the pouch which covers them may be patterned or roughened to provide a firmer grip.
After the member 2 has been formed the unfilled container is assembled. The member 2 is placed between the sheets of plastics material or inside the "afloat" tubing and the end 5 of the pouch, and, if _ _ - I
required, the edges 3, 4 of the pouch are sealed.
Simultaneously the sheets or tubing are sealed to the member 2 to provide the container. The sheets ox tubing may be sealed to the member 2 by, for example, (a) sealing the sheets 32, 33 on opposite aces of the member 2 as shown in Figure 6 or (b) by sealing one - sheet 34 to one face of the member 2 and sealing the other sheet 35 to the sheet 34 below the member 2 as shown in figure 7.
after the container has been formed it is filled with liquid via the port 9. After filling the closure I is inserted into the port 9 and sealed wherein for example by radio frequency welding and if required a similar closure is inserted into the port 10. The plug 29 and needle guide 30 are then inserted into the port and the covers 21, 22 are placed over the passageways 19, 20 respectively.
As an alternative to the use of the covers 21, 22 the larger diameter end of the passageways 19, 20 may be flattener and sealed as shown in Figures pa and 8b which show the passageway 19 on the port 9 before and err such treatment. In a similar manner the tapered ports pa, Iota illustrated in Figure 10 may be flattened and sealed as is depicted in Figures aye and 1lb. In this latter case the portion of the sealed passageway shown in Figure 1lb by dotted lines is removed after sealing After filling the container and its contents may be sterilized, for example, by heat sterilization. The filled container maybe over wrapped by a material which minimizes the loss of contents of the container by diffusion through the material of the container either before or after sterilization.

A spike, connected to a giving set which is ' used to administer the contents of the container to a it, S patient, is inserted into the port 9 and ruptures the Jo bate of the closure 25. The container may then be I;', suspended by the aperture 8 to permit the contents to be dispensed. If it is desired to add a medicament to -I the contents of the container the tab 15 is removed in :;.
' 10 a similar manner to that described above to expose tune outer end of the needle guide 30. The medicamerlt may then be added for example from a syringe by passing the needle through the bore of the needle guide 30, the plug 29 and into the container.
Winnie the tabs 14, 15 are in a position prior to use the outermost ends of the ports 9, 10 are maintained in a stroll environment. Removal of the tabs 14, 15 provides access to the ports in a , convenient manner which minimizes the possibility of 'I I the user touching and contaminating the outer ends of the ports. If the member 2 is manufactured by injection mounding techniques the thickness of the thin `. sections I aye, 17, aye, 18, aye and 18b can be , controlled so that the tabs 14, 15 can be easily i 25 removed when necessary but cannot be removed ! inadvertently. The presence of the member at said other end of the container enables the user to maintain a grip on the container when manipulating the tabs.
