Fluid container for use with a platen pump
First Claim
1. A flexible, generally inelastic medication container of the type for use with a compression pump for compressing the container to express a unit volume of medication therefrom, said container comprising:
- first and second opposing flexible walls for defining a chamber therebetween;
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 peripheral configuration of the medication container; and
an effluent fluid flow port on the container for providing fluid communication with said chamber;
wherein said outer peripheral configuration is generally circular.

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.
