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:
- applying a predetermined force to stretch a tubing segment;
- cutting the tubing segment at a predetermined length;
- and
- attaching the tubing segment to at least one connector to form a peristaltic pump cassette.
1 more element
A method for forming a peristaltic pump cassette, the method comprises;
- applying a force to a tubing segment to stretch the tubing segment to a predetermined length;
- cutting the tubing segment at a position correlated with the force necessary to stretch the tubing segment to the predetermined length;
- and
- attaching the tubing segment to at least one connector to form a peristaltic pump cassette.
1 more element
A method of improving accuracy in a pump cassette, the method comprising:
- selecting bulk tubing;
- stretching a segment of the tubing;
- cutting the segment of the tubing;
- and
- attaching at least one end of the segment of the tubing to a connector to form a pump cassette.
