摘要

PURPOSE: To enable elimination of blocking of a catheter and deposits around an orifice to be effectively carried out by flushing the catheter to be controllable. CONSTITUTION: This device is equipped with a drive unit 2 to drive a piston of a syringe by almost constant prescribed pressure and the syringe 12 is made to be filled with flushing liquid and to be connected to a port to flush the catheter.
