Clamp for connection of membrane lung in extracorporeal circulation

The invention discloses a clamp for connection of a membrane lung in an extracorporeal circulation, and belongs to the technical field of medical appliances. The clamp comprises a fixed clip seat and a membrane lung connecting flange, wherein the fixed clip seat comprises a lifting cap, an upper end cap, a lifting plate and a lower end cap which are sequentially connected from top to bottom, and four vertical clip columns are uniformly distributed on the annular circumference of the lower surface of the lifting plate; the lower end cap is connected with the upper end cap by virtue of a flange; four horizontal clip columns are uniformly distributed on the cylindrical side surface of the lower end cap; the membrane lung connecting flange is a round cylinder with a bottom, and a fixed hole connected to the membrane lung is formed in the bottom; a connector is arranged on the inner surface of the round cylinder; the membrane lung connecting flange and the fixed clip seat are detachably connected by virtue of the connector. According to the clamp, the membrane lung can be quickly assembled and disassembled by virtue of the membrane lung quick connecting flange only by means of lifting and rotating two actions, so that the membrane lung can be assembled and disassembled quickly and conveniently, and the operation time can be greatly reduced.
