[0002] In medical procedures such as hemodialysis or continuous hemodiafiltration, ECMO (Extracorporeal Membrane Oxygenation) or IABP (Intra-Aortic Balloon Pump), it is often necessary to connect two catheters.

[0003] A transparent protective cover is installed at the catheter connection point to seal the connection interface and prevent it from being directly exposed to the air. However, existing transparent protective covers for hemodialysis can only be used to fix one type of catheter. The fixing groove of the transparent protective cover does not match the catheter size. Various bacteria, viruses, and other microorganisms present in the air can come into contact with the catheter connection point through the gap between the fixing groove and the catheter and enter the bloodstream, increasing the risk of infection for the patient.

[0004] Therefore, how to design a transparent protective cover for hemodialysis that can be used with catheters of different sizes, effectively blocking airborne microorganisms from entering the interior of the protective cover and greatly reducing the risk of infection caused by exposure of the catheter connection is a technical problem that urgently needs to be solved by those skilled in the art.
