A development of force distribution measurement system around greater trochanter under pelvic belt

A pelvic belt is a tool of first aid for the pelvic fracture patients. This belt can stabilize the unstable pelvis and control bleeding from the arteries and organs inside the pelvis. The purpose of this study is to develop an evaluation system for the pelvic belt. Especially we evaluate the press around the greater trochanter under the pelvic belt. It has been reported that a pressure by tightening the belt increases the risk of tissue damage with pelvic belt. A mechanism which decreases the pressure of the tightening is required. We performed experiments that recorded pressure around the greater trochanter of right and left when subjects turned body. As a result, we confirmed that the pressure of the ipsilateral greater trochanter of the direction tends to increase with the same direction of subject turned.
