External end device for permanent catheters suitable for isolating liquid flow

摘要

An external end device for a permanent catheter that is suitable for isolating liquid flow from the environment can be connected on one side to two catheters (2, 2) and on the other side a closure lid (8 ) Or a main body (1) connectable to processing equipment. The body (1) is provided with two valves that block the flow of liquid in the two catheters in the form of so-called pinch valves (10, 10). The body (1) is a pinch valve sleeve. Two, functioning as pinch valve sleeves, compressible until their lumens are closed and located downstream of their respective catheters (2, 2) and upstream of their respective connectors (18, 18). A base element (6) housing the elastic tube (36, 36) and two elastic tubes (36, 36) to achieve closing and opening of the elastic tube by sandwiching and releasing the elastic tube, respectively; A cover element (7) for accommodating two flow control units (10, 10) for the pinch valve in an interacting position, That.
