Abstract
Abstract A releasable catheter retaining device is mounted on a pad of medical grade skin adhesive material. The device has a flange with a central hole, and a post extends from a surface of the flange opposite to the pad. An elongated tab extends from the post, there being a slot in the post for receiving the free end of the tab. With this arrangement, the tab can be passed through the slot after encircling a catheter which extends through the hole, in order to grip the catheter and to retain it in position.

Claim 1
Independent Claim
168 words
A releasable catheter retaining device comprising a substantially planar flange having a central hole therein and mounted on a pad of medical grade skin-compatible adhesive material, the flange being made in one piece with a post extending from the side of the flange opposite to the pad and with an elongated tab extending from the post, there being a slot in the post for receiving the free end of the tab, the arrangement being such that the tab can be passed through the slot after encircling a catheter which extends through the hole, and wherein the post has a resilient detent associated with the slot, the detent having a detent tooth, the detent and tooth being movable in a plane parallel to the plane of the flange between a first position in which the detent tooth grips the tab in the slot and a second position in which the tooth is disengaged from the tab and at least partially withdrawn from the slot and the tab is released.
