Medical puncture closure or plug, especially for use when blood vessels are punctured for medical procedures, has means for creating a counter- pressure chamber which is connected to a pressure chamber during use

摘要

Puncture closure has a pressure chamber (5) for the receipt of the body's own blood and an elastic cover element (4). The pressure chamber is at least partially surrounded by the glue element (3). The elastic cover element has means (6a) for forming a counter-pressure chamber (6) which is linked to the pressure chamber during use so that the counter- pressure chamber can be filled with blood during use. The counter-pressure chamber has counter-pressure surface (8) that exerts a pressure force towards the body or the glue layer during use.
