  • An extended portion 3d is formed to be wider to the left and right so as to be made, and the lower body portion 102 has a predetermined height H2 at a predetermined width W2 at a position corresponding to the pressure sensing region A. Protrude downward).
  • the tube When combined with the upper body portion 7 and the lower body portion 102 by the position of the above-described protruding pressure sensor 4 and the action of the pressure plate 7a, the tube is connected by the pressure sensor 4 and the pressure plate 7a. It is pressed up and down so that the pressure sensor 4 can detect the pressing force of the tube, and the tube down and down as much as it is expanded to the left and right extension portion 3d is formed so as not to disturb the flow of the fluid. .
  • the control unit 120 is one of the signals received from the pressure sensor 4 is a preset pressure set value If it is out of the range, it is preferable to stop the operation of the motor (M) or to generate a warning sound.
  • According to the present invention can prevent the flow of medical fluid such as fluid or fluid flowing inside the tube in the open state of the tube cover regardless of the pumping operation to continue the flow of a smooth flow, the constant pressure is maintained by the roller and tube support Applied to the tube has the advantage that a smooth pumping operation is possible.
  • the present invention provides a flow monitoring device for a medical liquid pumping device that can be prevented and has excellent durability and operability.
