Peristaltic pump and hose cartridge therefor

摘要

A hose cartridge for removably mounting a hose on a peristaltic pump has a roller wheel for pumping a fluid through the hose in a closed loop encircling an opening through which the roller wheel extends when the hose cartridge is mounted. A method for mounting such a hose cartridge includes introducing a holding rod of the pump into a holding portion of the hose cartridge, and carrying out a rotational movement of the hose cartridge about an axis defined by the holding rod until the working position of the hose cartridge is reached. The holding rod and the fixing bar both thus extend substantially parallel to the rotation axis of the roller wheel.

1. A hose cartridge (2) for removably mounting a hose on a peristaltic pump comprising a roller wheel (3) for pumping a fluid through said hose and a holding rod(17) and a fixing bar (15), the hose cartridge (1) comprising:
parallel to a rotation axis (R) of said roller wheel (3), said hose cartridge (2) substantially describing a closed loop encircling an opening through which said roller wheel (3) extends when the hose cartridge (2) is mounted on the peristaltic pump (1), the hose cartridge (2) being rotatably clamped on the holding rod (17) of the peristaltic pump, wherein said hose cartridge is rotatable around an axis defined by said holding rod to move within said opening between an initial cartridge position and a working position in which said hose is compressed between said roller wheel and said hose cartridge, wherein said holding rod and said fixing bar extend through said opening (20).
