摘要： 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. Said seal comprises a pressure chamber (23) which can be attached to the body in the area of the puncture opening and subjected to an overpressure, wherein the pressure chamber (23) has a supporting wall (21) in an area opposite to the body. In order to create a puncture seal, in which the pressure chamber (23) can be reliably sealed once the hypodermic needle has been removed, a sealing element (25) 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 supporting wall (21) to be punctured by the hypodermic needle.
