  • Publication number: 20110147380
    Abstract: A sterile container is provided which may be used for receiving and storing surgical instruments or surgical material. The sterile container comprises a receiving space formed by a container bottom and container walls, a lid for closing the receiving space, and a sterile barrier comprising a first carrier and a second carrier facing the first carrier. The first carrier and the second carrier define a sterile flow path therebetween in the form of a Pasteurian loop which establishes a fluid connection between the receiving space and an environment outside the sterile container. One of the first carrier and the second carrier are movable relative to the other of the first carrier and second carrier from a sterile position defining the sterile flow path to a overpressure position defining an overpressure flow path in which the one carrier has moved away from the other carrier.

  • Patent number: 7172740
    Abstract: The invention relates to a sterile container, in particular for the receipt and sterile storage of surgical instruments or material, comprising a receiving chamber and a gas exchange opening that can be sealed using a sterile filter. The aim of the invention is to prevent undesired liquid from reaching the sterile filter. To achieve this, the exterior of the lid is provided with at least one inflow edge, which faces away from the gas exchange opening, and falls away towards the exterior in relation to a lid plane.
