<P>PROBLEM TO BE SOLVED: To provide a coupler structure for easily filling a contact pressure sensor with a prescribed amount of air, which is a coupler structure for connecting the pressure sensor and a body, in regard to a contact pressure measuring instrument for measuring a contact pressure between a patient and bedclothes. <P>SOLUTION: This coupler structure 50 is for coupling the contact pressure sensor to the body 30 to which the pressure sensor is to be connected, the pressure sensor being equipped with sensor elements 40 filled with air therewithin for applying an air pressure to the exterior via tubes 23 connected thereto. Hard cylindrical tubes 51 are provided to ends of the tubes 23 while fit holes 38 are provided in one end of the body 30 with the cylindrical tubes 51 fit thereinto in a water-tight state. Pressure sensors are fixedly disposed in ends of the fit holes 38 to measure air pressure. When the cylindrical tubes 51 at the end of the tubes 23 are inserted into the fit holes 38, the prescribed amount of air in the fit holes 38 flows into the sensor elements 40 via the tubes 23 to fill the sensor elements 40 with the required amount of air to measure a contact pressure. <P>COPYRIGHT: (C)2011,JPO&INPIT |
