Fluid container for use with platen pump
First Claim
1. A compressible medication container for use in delivering fluid medication, said container comprising:
- first and second opposing flexible walls for defining a variable volume chamber therebetween, said chamber adapted to contain fluid medication;
an elongate seam for joining said first and second opposing walls to enclose the chamber therebetween, said seam extending generally in a plane through said container and defining an outer generally circular peripheral configuration of the medication container; and
an effluent fluid flow port on the container for providing fluid communication with said chamber, said fluid flow port being integral with said container and having an integral outlet tube extending from said port, said container adapted to be placed in and removed from a compression pump, wherein said container is sufficiently compressible to deliver a unit volume of medication from within said chamber when a force is exerted upon the compressible container by the compression pump.

Abstract
Disclosed is an infusion pump and a fluid container for expelling a fluid from the fluid container to a patient. The pump comprises a housing having a chamber therein for receiving the fluid reservoir. A first wall is provided on the housing for contacting the fluid reservoir, and a second wall is movable from a first position distanced from the first wall to form the chamber therebetween, and a second position relatively closer to the first wall. Advancing the movable wall from the first position to the second position expels fluid from the collapsible reservoir. Preferably, the first and second walls are provided with non-planar complementary surface configurations for contacting the collapsible reservoir. Retraction mechanisms for retracting the movable wall from the second position to the first position, and user readable indicium of the status of the dispensation cycle are also disclosed.

9. A collapsible fluid delivery bag, said collapsible bag of the type for removable insertion into a spring driven platen pump for compressing a pouch to expel fluid therefrom under a compressive force over a delivery cycle, said bag comprising:
-
a collapsible circular pouch formed by two circular layers circumferentially sealed to one another, said pouch adapted to enclose a volume of fluid between said circular layers;
an outlet tube integrally attached to said pouch and in fluid communication with the inside of said pouch; and
a restricted orifice attached to an outlet end of said outlet tube to restrict fluid flow to a precise level. - View Dependent Claims (10, 11)
