Title:
The pressure gauge for medical science
Document Type and Number:
Japanese Patent JP6099611
Kind Code:
B2
Abstract:
Provided is a pressure gauge capable of being effectively used for internal pressure measurement of a balloon catheter and capable of providing easy monitoring of a pressure value even when measuring internal pressure of an extracorporeal circulation circuit. The pressure gauge measures internal pressure of a balloon catheter used for treatment and diagnosis or pressure of a body lumen of a living body and includes a coil-shaped tube 2 to elastically deform. One end of the tube 2 is set as an open fixed end and the other end is set as a sealed free end and pressure introduced from the open fixed end can be measured based on a displacement position of the tube 2 due to the pressure.
