Abstract

PURPOSE:To simultaneously measure the secretory state of gastric juice in addition to the presence of the abnormality of intracoelomic tissue and the degree of the damage thereof, by providing an opening part allowing body fluids to fill and an ion responsive sensor measuring the concn. of the ion of the body fluids to the leading end of an intracorporeal insert part. CONSTITUTION:When the examination of intracoelomic tissue, for example, a gastric ulcer is performed using this intracoelomic examination apparatus, the leading end of an insert part 2 is inserted in the stomach while the body cavity is observed to perform the photographing of the walls of the stomach. The opening part 11 at the leading end of the insert part 2 is filled with secreting fluid such as gastric acid. An ion responsive type field-effect transistor (ISFET) 7 reacts with the secreting fluid to generate electric output proportional to the concn. of the ion of the secreting fluid. This electric output is led out to a display apparatus 20 through a signal wire 9 to perform amplification, A/D conversion, numerical conversion to ion concn., display or memory. Therefore, simultaneously with the observation of the tissue in the body cavity being the inherent purpose of an endoscope, the secretory state of the secreting fluid such as gastric acid considered to be the cause of the damage of the tissue can be also known.
