Kind Code:
A1
Abstract:
Provided is a pressure gauge that can be effectively used to measure the internal pressure of a balloon catheter, and with which it is possible to readily confirm the pressure value when measuring the internal pressure of an extracorporeal circulation circuit. A pressure gauge for measuring the internal pressure of a balloon catheter used in treatment or diagnosis, or for measuring the pressure of internal lumen of a living body; provided with an elastically deforming tube 2 having a coil shape. One end of the tube 2 acts as an open fixed end 4, while the other end acts as a sealed free end 3, and the pressure is measured from the displacement position of the tube 2 due to the pressure introduced from the open fixed end.
