Title:
カテーテル・シミュレーター用拍動流生成ポンプ
Document Type and Number:
Japanese Patent JP6927480
Kind Code:
B2
Abstract:
The pump (10) includes a cylinder (13) provided inside with a piston performing a reciprocating motion; a driving motor (15) causing the piston to perform a reciprocating motion; a link mechanism (19) converting the rotational motion of the driving motor (15) to the reciprocating motion of the piston; an extrusion port (86b), through which a liquid inside the cylinder is extruded to the outside by the piston; a suction port (86a), through which a liquid from the outside is sucked into the cylinder; and a control unit 70 for controlling the rotation of the driving motor 15. The control unit 70 controls the driving motor 15 so as to output pulsatile flows at a rate of 20 times to 200 times per minute.
