Abstract
Abstract An enclosure is provided for protecting a bag containing fluid used in connection with a pump for pumping the fluid to the patient. The pump closes off the opening into the enclosure. A first end of the pump is positioned within the enclosure adjacent to a retaining lip. A latch structure latches a second end of the pump to the enclosure to mount the pump to the enclosure. A bag spike chamber is provided for receiving a bag spike used to connect the pump to the bag. A platform is provided for supporting the bag above the bag spike chamber. A ridge on the front of the control module of the pump engages the enclosure during mounting of the pump to the enclosure. A ridge on the back of the control module fits into the enclosure. The enclosure further includes a pressure plate support surface for engaging a reciprocally shaped pressure plate to facilitate a mechanical fit of the pressure plate to the enclosure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A pressure plate for use with a pump comprising: body construction including: a top surface configured for receipt of a tube, the top surface including two longitudinal edges, and two side edges extending between the two longitudinal edges, the tube having a section extending in a direction generally parallel to the two longitudinal edges; a bottom surface with a first portion facing in an opposite direction to the top surface, the bottom surface including a three sided ridge configuration in a U-shape projecting outwardly from the first portion, the U-shape including first and second arms joined by a connecting section, the connecting section being a longitudinal surface extending in a direction generally parallel to the two longitudinal edges, and the first and second arms being two side surfaces extending from opposite ends of the longitudinal surface transverse to the longitudinal surface, and wherein the longitudinal surface and the first portion intersect forming a continuous, angled interface.
Claim 2
Dependent Claim
156 words

Claim 3
Dependent Claim
15 words
The pressure plate of claim 1, wherein the continuous angled interface is about 90 degrees.
Claim 4
Dependent Claim
23 words
The pressure plate of claim 1, wherein an area between the longitudinal surface and the two side surfaces is a solid, continuous surface.
Claim 5
Dependent Claim
15 words
The pressure plate of claim 1, further comprising a tube mounted to the pressure plate.
Claim 6
Dependent Claim
43 words
The pressure plate of claim 4, further comprising a back surface including an entry port for permitting the tube to enter the pressure plate, and an exit port in one of the side edges for permitting the tube to exit the pressure plate.
