Disclosed herein are devices and methods related to UV disinfection of a transfer catheter during peritoneal dialysis. The transfer catheter comprises a first and second end, the second end comprising a transfer valve. The transfer valve body comprises an inlet, outlet, and a flush hole. The valve core comprises a notch configured to allow fluid flow between the various flow paths. The valve core and body are positioned off axis with respect to the fluid flow path. The transfer catheter can allow for a small volume kill zone, which can minimize the amount of UV required to disinfect the catheter.

Transfer catheter for ultraviolet disinfection

Systems and methods of disinfection of catheter connections are provided. A transfer catheter connector can include a UV-transparent window at its distal end and a sealing plunger proximal to the UV-transparent window. A solution set connector can be inserted inside a portion of the transfer catheter connector to connect a solution set and transfer catheter. The solution set connector comprises a lumen covered by a leading membrane surface; a sealing surface configured to sealingly engage the window surface, and a piercing member configured to pierce the membrane surface. The sealing plunger, membrane surface, and window define a disinfection zone. The connectors can be connected in a disinfection position configuration in which flow is not permitted between the catheters and the connectors are irradiated with UV light. After disinfection, the connectors are advanced to a flow position in which the piercing member pierces the membrane surface, enabling flow between the catheters.
