Abstract

This paper introduces a 4-electrode gastric-emptying measurement system using an electrical bio-impedance method by which gastric-emptying experiments of 24 healthy volunteers have been carried out. The test results show that the base impedance is stable, the average GET/2 is 8.78 +/- 1.76 min. The new system provides a new non-invasive measurement method for the clinical study on gastric-emptying functions.

摘要

本文介绍了一种采用生物电阻抗法的四电极胃排空测量系统，利用该系统对24名健康志愿者进行了胃排空实验。测试结果表明，基础阻抗稳定，平均半排空时间为8.78±1.76分钟。该新系统为胃排空功能的临床研究提供了一种新的非侵入性测量方法。
