INFUSION PUMP
First Claim
1. An apparatus for delivering fluid at a substantially constant flow rate, the apparatus comprising:
- a pair of substantially rigid surface elements for defining a volume that is variable according to constrained separation of the pair of surface elements;
a support member disposed within the volume defined by the pair of surface elements; and
a holding reservoir disposed within the volume defined by the pair of surface elements, the holding reservoir being attachably fastened at a first end to the support member and attachably coupled at a second end to the pair of surface elements by a hinge assembly comprising at least one hinge and a receptacle for receiving the second end of the holding reservoir.

Abstract
An apparatus for delivering fluid at a substantially constant flow rate includes a pair of substantially rigid surface elements for defining a volume that is variable according to constrained separation of the pair of surface elements. The apparatus further includes a support member disposed within the volume defined by the pair of surface elements; and a holding reservoir disposed within the volume defined by the pair of surface elements. The holding reservoir is attachably fastened at a first end to the support member and attachably coupled at a second end to the pair of surface elements.

21. An infusion pump comprising:
-
a pair of substantially rigid surface elements for defining a volume that is variable according to constrained separation of the pair of surface elements; a generally cylindrical fixed-length support member disposed within the volume defined by the pair of surface elements, wherein a first end of the support member is attachably fastened to the pair of surface elements and a second end of the support member extends through the volume defined by the surface elements without coming into contact with any portion of the pair of surface elements; and a holding reservoir disposed within the volume defined by the pair of surface elements, wherein a first end of the holding reservoir is attachably fastened to the first end of the support member and a second end of the holding reservoir is attachably coupled to the pair of surface elements by a hinge assembly comprising at least one hinge and a receptacle for receiving the second end of the holding reservoir.
