  • Publication number: 20230218879
    Abstract: The present invention relates to a method for disconnecting two fluid-conducting line sections of a medical device which are detachably interconnected, wherein a first line section of the two line sections has at least partially an elastic property. The method comprises the steps of enclosing a fluid volume in the two line sections, generating a reduced pressure in the two line sections, as a result of which elastic deformation from a starting position into a tensioned position takes place in and/or on the first line section, wherein a fluid volume contained in the first line section is lower in the tensioned position than a fluid volume contained in the starting position, and detaching the connection of the line sections, wherein the fluid volume contained in the first line section in the tensioned position increases. Furthermore, the invention relates to a medical device which is configured to carry out a method of this kind.
