Problems solved by technology

[0002] Medical research has found that most (95% of BE patients and 79% of GERD patients) esophageal reflux is mixed gastric and duodenal reflux [1], duodenogastroesophageal reflux (DGER) is the cause of reflux It is an important pathogenic factor of sexual esophagitis, Barrett's esophagus, stricture, ulcer, dysplasia and even esophageal adenocarcinoma[2]. The method of measuring DGER has been poor, and there is no similar instrument for clinical use

Embodiment Construction

[0023] This gastric juice and bile reflux monitor includes a light transmitter, a light receiver, an optical fiber, a probe, an analog-to-digital conversion circuit, a system controller, a memory, a display, a communication controller, and a keyboard. Under the control of the system controller, the reference light and test light can be driven in time sharing, and the time and data of data collection can be recorded and stored:

[0024] Probe 1: It is composed of a light reflector 10, a connector 11 and an optical fiber head 12. The emitted light is emitted from the optical fiber head 12, reflected by the reflector 10, enters the optical fiber 13 and returns to the optical receiver 3. The connector 11 ensures that the distance between the reflector 10 and the optical fiber interface 12 is 2 mm.

[0025] The optical fiber 2 is composed of a multi-core optical fiber bundle. The front head 12 of the optical fiber is connected to the probe 1, and the tail part of the optical fiber 2 is...

Abstract

The invention discloses a reverse-current monitor of gastric and bile, which comprises the following parts: optical emitter, optical receiver, optical fiber, probe, modular switching circuit, system controller, memory, display, communicating controller and keyboard. The invention possesses significant auxiliary action for esophagic reverse-current disease, which provides reliable diagnosis reference for doctor.

Description

Technical field [0001] The invention relates to the technical field of medical electronic instruments, in particular to a gastric juice and bile reflux monitor that detects gastric juice and bile reflux through optical fiber detection. Background technique [0002] Medical research found that most of the esophageal reflux (95% of BE patients and 79% of GERD patients) is a mixed gastric and duodenal reflux [1], and duodenal gastroesophageal reflux (DGER) is caused by reflux. Esophagitis, Barrett’s esophagus and stenosis, ulcers, dysplasia and even esophageal adenocarcinoma [2], the World Health Organization (WHO) has listed bile reflux as a type of carcinogen, but it is accurately quantified in the human body The method for measuring DGER has been poor, and there is no similar instrument for clinical use. Summary of the invention [0003] The purpose of the present invention is to develop a bile reflux monitor device that can monitor the bile reflux in the gastric juice of a pati...
