Patent Images
1. A peristaltic pump hose cassette, comprising:
- a cassette housing with a circular segment and at least one pump connection surface for engagement with a peristaltic pump for connection to the peristaltic pump for use and for disconnection from the peristaltic pump for disposal;
a flexible hose extending through said cassette housing, said flexible hose being guided in said cassette housing along said circular segment, said cassette housing having a cutout for the engagement of a roller wheel of a peristaltic pump into the interior of said circular segment;
tool-less connection elements connected to the cassette housing for connecting said cassette housing connection surface to the peristaltic pump and disconnecting said cassette housing connection surface from the peristaltic pump for disposal; and
a displaceable hose leg portion connected to said flexible hose, said displaceable hose leg portion extending adjacent to said circular segment, said displaceable hose leg portion being moveable relative to said cassette housing and displacing said flexible hose to hold said flexible hose in one of a mounting position and an operating position in the cassette housing.

Abstract
A hose cassette (1), for a peristaltic pump (2), includes a cassette housing (3) and a flexible hose (4) extending through cassette housing (3). The hose (4) is guided in the cassette housing (3) along a circular segment. The cassette housing (3) has a cutout (5) for the engagement of a roller wheel (6) of a peristaltic to pump (2) into the interior of said circular segment. The hose cassette has connection elements (7), (8) for connecting the cassette housing (3) to the peristaltic pump (2). At least one hose leg (9), (10) to be connected to the circular segment is displaceably held between a mounting position and an operating position in the cassette housing (3).
