Compliant rotor for an improved cartridge for drug infusion pump |
摘要 |
An improved rotor for use with a segmented peristaltic cartridge comprising a housing and a cover for assembly, said assembled housing and cover defining a pumping chamber which holds the improved rotor, a rotor sleeve and a section of flexible tubing wrapped around the rotor and connected to respective inlet and outlet ports of the cartridge. The flexible rotor includes an eccentric structure wherein flexible beam members provided on an outer surface of the rotor form a compliant member which improves the flexibility of the rotor assembly to avoid excessive compression loads or high torque and/or dynamic leak back or low torque for the tubing in the cartridge.
