Abstract
The present invention relates to a puncture seal for sealing a blood vessel having a puncture opening in a body of a human being or an animal. The seal comprises a pressure chamber which can be attached to the body in the area of the puncture opening and subjected to an overpressure, wherein the pressure chamber has a supporting wall in an area opposite to the body. In order to create a puncture seal, in which the pressure chamber can be reliably sealed once the hypodermic needle has been removed, a sealing element made of a material with a certain elastic return force, which is at least 1 mm thick is provided and placed in the area of the support wall to be punctured by the hypodermic needle.
