AN OPEN/CLOSE MECHANISM OF PASSIVE MECHANICAL INTERFACE AND A FINGER-TYPE PERISTALTIC INFUSION PUMP

摘要

The present invention discloses an OPEN/CLOSE mechanism which comprises of a passive mechanical interface (MS) and a finger-type peristaltic infusion pump (DDS). The MS is an elongated member characterized by upstream and downstream opposite ends, integrally accommodating a portion of a flexible infusion-tube, the main longitudinal axis of said tube is parallel to the main longitudinal axis of said MS. The MS comprises modules selected from a group consisting (i) a saddle-like catch (saddle), located at one end of the MS, preferably the downstream end; and (ii) a toothed interface located at the opposite end of the MS, preferably the upstream end, the interface is adapted to accommodate at least one catch securely and reversibly fastening said MS in an OPEN configuration. The invention also presents methods for providing this OPEN/CLOSE mechanism.
