METHOD AND APPARATUS FOR MEASURING OF INTESTINAL POTENTIAL DIFFERENCE

摘要

The present invention relates to a method and an apparatus for producing a transmucosal potential difference (PD) signal essentially being unaffected by intestinal motor activities. This is accomplished by reducing the PD signal based on time variations in the intraluminal pressure (IP) signal. The invention also relates to different applications of such a signal, such as measurement of the total peripheral resistance (TPR), detection of abnormalities in the enterical nervous system, detection of damages in the mucosal barrier.
