Abstract
A method for forming peristaltic pump cassettes includes cutting tubing segments to different lengths based on the physical properties of the individual tubing segments. The size variations compensate for the physical parameters of the tube and improve accuracy in a peristaltic pump using the cassettes.
Claims20
A method for forming a peristaltic pump cassette, the method comprising:
- attaching at least one connector to a tubing segment;
- applying a predetermined force to stretch the attached tubing segment;
- cutting the attached tubing segment at a predetermined length;
- and
- attaching the at least one connector with the tubing segment to the peristaltic pump cassette.

A method for forming a peristaltic pump cassette, the method comprising:
- attaching a connector to a tubing segment;
- applying a force to the attached tubing segment to stretch the tubing segment to a predetermined length;
- cutting the attached tubing segment at a position correlated with the force necessary to stretch the tubing segment to the predetermined length;
- and
- attaching the connector with the tubing segment to the peristaltic pump cassette.
2 more elements
A method of improving accuracy in a pump cassette, the method comprising:
- selecting bulk tubing;
- attaching a first connector to a first end of the tubing;
- stretching a segment of the attached tubing;
- cutting the segment of the attached tubing;
- and
- forming the pump cassette by attaching a second end of the tubing to a second connector.
