Definitions

• the present invention concerns an improved bag for infusions and in particular a bag for infusion, said bag being suitable for the admixture of intravenously administered pharmaceuticals.
• Bags for infusion containing a non-therapeutical liquid, for example saline (9 mg per ml NaCl) or glucose (50 mg per ml) are routinely used for the administration of pharmaceuticals.
• a hospitalised patient is given a bag for infusion, connected via a cannula to suitable vein, mostly a vein on the back of the hand.
• Pharmaceuticals to be administered intravenously to the patient can then be injected in the bag for infusion.
• the pharmaceutical is prepared in the hospital pharmacy or at the ward by medical personnel, by injecting the pharmaceutical in the bag for infusion.
• US-A-5,053,012 provides an example of this: in the general context of the document, which relates to an apparatus for pressurising infusion bags (and thus only indirectly with infusion bags as such), a conventional infusion bag 12 is shown in Fig 1, fitted with an outlet port 16 adapted to be punctured by a coupler 18 of a recipient set.
• the bag 12 is furthermore fitted with an injection port 28 for the purpose of injecting a drug into the liquid in the bag to be administered.
• DE-A-3, 244,151 discloses a medical storage bag made of a flexible plastic material which has at least one outlet nozzle sealed with a mem- brane.
• the outlet nozzle has an adapter piece with an annular bead on the internal surface, which permits use of differently dimensioned connecting needles of infusion devices without having to use excessive force to penetrate the membrane.
• a transfer adapter which includes a special two-way cannula or needle having a protective cylinder, said cylinder being of a diameter adapted to the cap of the vial.
• soft bags are manufactured of poly vinyl chloride PVC
• semi-rigid bags are manufactured of one or a mixture of the polymer materials polyacetate (PA), polypropylene (PP) and polyethylene (PE)
• PA polyacetate
• PP polypropylene
• PE polyethylene
• the rigid, almost bottle-like containers are manufactured of one of the above polymer materials PA, PP and PE.
• FIG. 1 shows a bag for infusion according to the present invention
• Fig. 2 is a side view of the bag in Fig. 1,
• Fig. 3 is detailed cross-sectional view of the first inlet/outlet of the bag in Fig. 1
• Fig. 4 is detailed cross-sectional view of the second inlet/outlet of the bag in Fig. 1
• Fig. 5 shows, in perspective view, the different components; vial, transfer adapter and bag according to the present invention.
• a normal bag for infusion comprises a liquid filled cavity of a certain, suitable volume. This volume is generally in the interval of one hundred to one thousand millilitres.
• the bag further comprises means for suspension, for example a loop arranged in the bag material, above and outside the liquid filled area.
• a bag for infusion comprises one or more inlets/outlets for the addition and/or withdrawal of liquid.
• Said inlets/outlets comprise, according to the prior art, at least one membrane suitable to be penetrated with a cannula.
• the other inlet/outlet if altogether present, can be a cou- pling such as a threaded coupling or a bayonet mount for the attachment of a syringe or tubing.
• an infusion bag 10 has two inlets/outlets 20, 40 for the addition and/or withdrawal of liquid.
• the first inlet/outlet 20, shown in more detail in Fig. 3, comprises a membrane 30, and the second inlet/outlet 40, shown in more detail in Fig. 4, comprises a mechanical valve 50.
• the valve 50 opens when a syringe 100 is inserted, as illustrated in Fig. 5, and closes when said syringe 100 is removed, and the membrane 30 has a removable seal 60, adapted to be combined with both a needle and an infusion apparatus, and said membrane being enclosed in a casing 70, adapted to fit in a transfer adapter 90.
• this first and second inlet/outlet 20, 40 are extended from the liquid filled part of the bag 10 for infusion in order to avoid hindering the normal use of a transfer adapter 90. Additionally, the first and second inlet/outlet 20, 40 are arranged at a distance from each other, said distance allowing convenient access to the inlets/outlets 20, 40.
• one of these two inlets/outlets 20 comprises a penetrable membrane 30, preferably enclosed in a Tulip -type membrane holder or port, adapted for use with a so- called transfer adapter 90.
• the other inlet/outlet 40 comprises, according to one embodiment of the invention, a coupling with an outer thread, preferably the male part of a so-called Luer ® -lock.
• said inlet/outlet 40 comprising the coupling preferably comprises a valve 50 which, under mechanical influence, allows the transport of fluid in or out of the bag 10 for infusion.
• a valve 50 which, under mechanical influence, allows the transport of fluid in or out of the bag 10 for infusion.
• a valve 50 which, under mechanical influence, allows the transport of fluid in or out of the bag 10 for infusion.
• One example of such valve is an elastic plug 80, arranged in narrowing of the inlet/outlet 40, reachable with the tip of a syringe 100 when said syringe is locked to the threaded coupling. The tip of the syringe 100 compresses the elastic plug 80 and thereby the inlet/outlet 40 is held open.
• these two inlets/outlets 20, 40 are at a suitable distance from each other. Preferably they are placed at least 40 millimetres from the liquid filled part of the bag 10 for infusion. Further the centreline of each two inlets/outlets 20, 40 run parallel at the distance of at least 35 mm.
