METHOD AND SYSTEM FOR PROVIDING ADJUSTABLE COMPRESSION FORCE ON A TUBE IN A PERISTALTIC PUMP
First Claim
1. A cassette for use in a peristaltic pump, the cassette comprising:
- a cassette frame configured to mount to a peristaltic pump and to receive a tube;
a cam;
a cam position selector switch; and
a biasing member mounted to the cam and to the cassette frame and operably coupled with the cam position selector switch so that movement of the cam position selector switch adjusts a position of the cam relative to the cassette frame.

Abstract
A cassette for use in a peristaltic pump is provided. The cassette includes a cassette frame, a cam, a cam position selector switch, and a biasing member. The cassette frame mounts to the peristaltic pump. The biasing member mounts to the cam and to the cassette frame and operably couples with the cam position selector switch. Moving the cam position selector switch in a first direction releases the cam position selector switch from the cassette frame. Moving the cam position selector switch in a second direction after releasing the cam position selector switch from the cassette frame adjusts a position of the cam relative to the cassette frame. The second direction is approximately perpendicular to the first direction.

18. A method of adjusting a position of a cam in a peristaltic pump, the method comprising:
-
mounting a cassette to a peristaltic pump, the cassette comprising a cassette frame;
a cam;
a cam position selector switch; and
a biasing member mounted to the cam and to the cassette frame and operably coupled with the cam position selector switch;
moving the cam position selector switch in a first direction to release the cam position selector switch from the cassette frame; and
moving the cam position selector switch in a second direction after releasing the cam position selector switch from the cassette frame to adjust a position of the cam relative to the cassette frame, wherein the second direction is approximately perpendicular to the first direction.
