Abstract
We purpose to designed system that be able to measure long time and non-invasive the bowel motility. It is because there is no device that is appropriate for measurements of the bowel motility. Therefore, the method of using the sound was devised and examined it. The sound of bowel is assumed to be in activity. Moreover, it made comparative study of the cycle of the interdigestive migrating motility complex(MMC) with the sleep cycle. As a result, the periodicity of the bowel motility was able to be measured according to the borborygmi. Additionally, the measurement of the bowel motility by the borborygmi was able to be confirmed. The relativity of the interdigestive migrating motility complex(MMC) and sleep cycle was not able to be confirmed.
