Medical Connector With A Reversibly Deformable Lobe

摘要

A connector for coupling to a base of medical device equipped with a circular hub having a circumferential recess. The connector includes a cap having a top surface, a bottom surface, a central region, and a circumferential region. The cap defines at least two slots extending from the circumferential region towards the central region, the slots defining the cap into at least one lobe. The at least one lobe has an outward projecting lift tab and an inward projecting catch. Positioning the connector on the circular hub and depressing the connector engage the catch with the circumferential recess of the circular hub so the connector can rotate completely about the circular hub. Lifting the one lift tab to reversibly displace the lobe and its respective catch radially to disengage from the circumferential recess decouples the connector.

主权项

1. A connector for coupling a medical fluid supply tube to the head of a catheter device having a circular hub with a circumferential recess defined in a side surface of the circular hub, the connector comprising:
a cap having a top surface, a bottom surface, a central region, and a circumferential region; the cap defining at least two slots, each slot extending from the circumferential region of the cap towards the central region, the slots defining at least one lobe, the at least one lobe including:
an outwardly projecting lift tab,an inwardly projecting catch that is configured to releasably engage the circumferential recess, andat least a resilient region; wherein the connector is free to rotate completely about the circular hub, and wherein the connector decouples from the circular hub by lifting at least one lift tab to reversibly displace the lobe and its respective catch radially by deforming the resilient region, in order to disengage from the circumferential recess.
