1A1-A22 Basic Study on Development of Capsule-type Intestinal Treatment Device Using Vibration

Abstract

Many patients suffer from complications caused by surgical operations. The ileus which comparatively happens frequently is one of the complications. The cause of the ileus after a surgical operation is debility of peristalsis. Therefore, we propose the vibratory capsule device which activates the peristalsis of small intestine from the inside of patient's body, and make a prototype of vibratory capsule device. Moreover, the vibration spread characteristic to the surrounding of a flexible thing was measured as a technological approach. First of all, the experiment that used the gelatinizer was conducted, the experiment that used pig's enteric canal was executed afterwards, and the results were compared.
