A Development of Force Distribution Measurement System Around Greater Trochanter Under Pelvic Belt

Abstract

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 pressure around greater trochanter under pelvic belt. It is reported that a pressure by tightening the belt increases the risk of tissue damage with pelvic belt. A mechanism which decreases the pressure by the tightening is required. We performed experiments that recorded pressure around greater trochanter of right and left when subjects turned body. As a result, we confirmed that the pressure of the contralateral greater trochanter of the direction tends to increase with the same direction of subject turned.
