| 摘要 |
The invention discloses an anti-free flow mechanism for a finger-type peristaltic infusion pump (DDS) comprising: a passive mechanical interface (MS) which integrally accommodates a portion of a flexible infusion-tube, and an anti-free flow valve (AFFV) which is a spring-activated latch incorporated with the (MS). The maneuverable latch is secured in the (MS) either in a closed or opened configuration: in its closed configuration no flow is provided and in its opened configuration, a free flow is facilitated. The anti-free flow is configured in a manner that when the (MS) is not properly mounted in the (DDS), the (AFFV) is automatically actuated to its closed configuration, and vice versa that when the (MS) is properly mounted in the (DDS), the latch is adapted to be automatically switched to the opened configuration The invention also presents methods for avoiding anti-free flow in finger-type peristaltic infusion pumps. |
