Accepts healthy volunteers


In order to validate that the VIPUN, Gastric Monitoring System (GMS) is a gastric motility monitoring system, we intend to show that the VIPUN GMS can assess motility through pressure measurement similar to high-resolution manometry (HRM).

In addition, the study aims to contribute to the design and development of a position confirmation functionality integrated in the VIPUN Gastric Monitoring System by establishing volume-pressure relations in the stomach and esophagus.
