Abstract
The present invention discloses an anti-free flow mechanism for a finger-type peristaltic infusion pump (DDS) and methods for avoiding anti-free-flow. The mechanism comprises: a passive mechanical interface (MS) which integrally accommodates a portion of the flexible infusion tube, and an anti-free flow valve (AFFV) which is a spring-activated latch, which is incorporated within said MS. The maneuverable latch is secured in the MS either in CLOSED or OPEN configurations: in its CLOSED configuration no flow is provided, and in its OPEN configuration, a free flow is facilitated. Said anti-free flow mechanism is configured in a manner such that when the MS is not properly mounted in the DDS, said AFFV is automatically actuated via one or more integrated springs, to its CLOSED configuration. When the MS is properly mounted in the DDS, said latch is adapted to be automatically switched to the OPEN configuration.
