<P>PROBLEM TO BE SOLVED: To provide a liquid circulation or injection device into the living body, effective in cooling the spinal cord, brain or esophagus locally and continuously. <P>SOLUTION: The liquid circulation or injection device includes: a synchronous alternating function two-tube parallel type syringe type pump which consists of two syringe type pumps, and can repeat a reciprocating motion in an opposite direction by turns at the same period, and in which pressure monitoring is possible; and a pressure resistance circuit in which two Y-shape branch tubes which have one-way valves of a reverse direction made into a pair with each branched part and two Y-shape branch tubes which do not have a valve are combined. The liquid circulation or injection device can correctly control the flow rate and the flowing pressure of circulating cooling water, can assure high flowing pressure, and is effective in cooling the spinal cord, brain or esophagus locally and continuously. <P>COPYRIGHT: (C)2012,JPO&INPIT |
