A dressing (10) for effecting haemostasis at the site (32) of a vascular puncture after withdrawal of a needle or cannula comprises a base strip (12) having an adhesive undersurface protected by removable panels (14, 16) and having mounted thereon a pad (18). An eye (26) is secured above the strip (12) and has passing therethrough the shank (44) of a draw strip (20) which, after being drawn to approximate the end portions of the strip (12), may have its free and (20b) adhered to the upper surface of its root portion (20a). After application of the dressing (10) the skin (36) under the pad (18) is subjected to a pressure sufficient to restrict flow through the punctured vessel (32) and achieve haemostasis. Alternatively the end portions of the base strip (12) may be approximated by opposed draw members. Other arrangements for generating a pressure over the puncture site are disclosed. |
