一种采用光学多道分析技术配合胃镜快速、无创伤地测定胃粘膜血供参数（ 血氧饱和度、血红蛋白和氧合血红蛋白） 的新型装置。介绍了测量原理、仪器结构以及在临床上的一些测量结果，表明仪器在胃体不同部位和胃溃疡部位进行测量，能为临床诊断提供依据。
A novel device for the rapid and non-invasive measurement of gastric mucosal blood supply parameters (oxygen saturation, hemoglobin, and oxyhemoglobin) using optical multichannel analysis techniques combined with gastroscopy. The measurement principle, instrument structure, and some measurement results in the clinic were introduced. It is shown that the instrument is used to measure different parts of the stomach and gastric ulcer, which can provide a basis for clinical diagnosis.
