The invention describes a connection system comprising at least a male connecting element and a female connecting element which can be connected to each other, as well as the male connecting element and the female connecting element. The location of contact of the two connecting elements is preferably provided with a disinfecting adhesive so that an aseptic or sterile connection can be established. Therein both connecting elements have predetermined breaking points which in the connected state are arranged one above the other so that only one breaking point within the tube is obtained via which an aseptic fluid guidance through two tubes from one sterile system to another sterile system can be carried out. Thereby a particularly simple and cost-saving connection is created which fulfills the highest sterility requirements. Furthermore, also the use of such a connection system is described.
A connection system for the connection of in particular two or more sterile systems, comprising at least a male connecting element (2) forming a closed end of a sterile, fluid-containing system and at least a female connecting element (1) forming the closed end of a second sterile, fluid-containing system which can be aseptically connected to one another,
A connection system according to one or more of the preceding claims, characterized in that the connecting elements (1, 2) can be connected to each other by means of a screw thread.
A connection system according to one or more of the preceding claims, characterized in that the connecting elements (1, 2) can be connected to each other by means of a snap-in connection.
A connection system according to one or more of the preceding claims, characterized in that the connecting elements (1, 2) can be connected to each other by means of an adhesive connection.
A connection system according to one or more of the preceding claims, characterized in that the adhesive connection is a quick-hardening adhesive.
A connection system according to one or more of the preceding claims, characterized in that a disinfectant is provided between the contacting contact surfaces (9, 11) of the connecting elements (1, 2).
A connection system according to the preceding claim, characterized in that the disinfectant has bonding properties.
A connection system according to the preceding claim, characterized in that the disinfectant is a quick-hardening adhesive.
A connection system according to one or more of the preceding claims, characterized in that cyanoacrylate is provided for connecting the two connecting elements (1, 2).
A connection system according to one or more of the preceding claims, characterized by a protective cap (22) the external contour of which is matched to the male connecting element.
A connection system according to one or more of the preceding claims, characterized by a protective cap (22) in the form of a male connecting element that is connectable to the female connecting element (1) for the protection thereof.
A female connecting element (1) which forms the closed end of a fluid-containing system, for the connection with a male connecting element (2) which forms the end of a second fluid-containing system, characterized in that the female connecting element (1) has a predetermined breaking point (8).
A male connecting element (2) which forms the closed end of a fluid-containing system, for the connection with a female connecting element (1) which forms the end of a fluid-containing system, characterized in that the male connecting element (2) has a predetermined breaking point (7).
