Abstract: The present disclosure provides a method for hemodialysis of blood, comprising providing a hemodialysis catheter having a low recirculation distal tip, a first and a second extension tubes that are configured to be connected to a dialysis machine, providing a hemodialysis machine with an arterial patient connector and a venous patient connector; conducting hemodialysis with the first extension tube connects to the arterial patient connector of the dialysis machine, and the second extension tube connects to the venous patient connector of the dialysis machine; and periodically reversing the first and second extension tubes connections to the arterial and venous patient connectors of the dialysis machine in a subsequent hemodialysis. The present disclosure also provides a hemodialysis catheter, comprising a switchable connection indicator indicating connection to arterial or venous flow path. The switchable connection indicator can be integrated with a clamp.
