Gastroscopy equipment for internal medicine

Abstract

The invention discloses gastroscopy equipment for internal medicine, and belongs to the technical field of electronic gastroscopes. The gastroscopy equipment comprises a guide tube, a camera is mounted at the head end of the guide tube, a positioning seat is mounted on the inner wall of the guide tube, a sampling bag is arranged on the positioning seat, a first liquid guide tube is arranged at one end of the sampling bag, a second liquid guide tube is arranged at the other end of the sampling bag, the first liquid guide tube and the second liquid guide tube both communicate with the sampling bag and are both fixed on the positioning seat through a clamping and limiting mechanism, and an extrusion mechanism is arranged above the sampling bag. According to the gastroscopy equipment for the internal medicine, the guide tube is inserted into the gastric cavity of a patient, the sampling bag is extruded through the extrusion mechanism, gastric juice in the body of the patient enters the sampling bag through the first liquid guide tube in a negative pressure state, and the first liquid guide tube is clamped by the clamping and limiting mechanism, so that a gastric juice sample in the sampling bag is prevented from being completely leaked from the first liquid guide tube, gastric juice in the body of the patient can be sampled, and the diagnosis accuracy of doctors is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electronic gastroscopy, in particular to a gastroscopic inspection device for internal medicine. Background technique [0002] Electronic gastroscope is a medical electronic optical instrument that can be inserted into the human gastric cavity for direct observation, diagnosis and treatment of gastrointestinal diseases. It is mainly composed of an objective lens system, an image array photoelectric sensor, and an A / D conversion integrated module. The object in the gastric cavity is imaged on the image array photoelectric sensor through the tiny objective lens system, and then the received image signal is transmitted to the image processing system, and finally the processed image is output on the monitor. Electronic gastroscopy can obtain high-definition images, and various image processing can be performed through the computer, such as three-dimensional imaging, measurement of mucosal blood flow, local h...

Problems solved by technology

[0003] Gastroscopy equipment for internal medicine sometimes needs to sample the gastric juice in the patient's body when examining the patient to improve the accuracy of the doctor's diagnosis. Sampling will affect the doctor's diagnosis. Therefore, there is an urgent need for a gastroscopy device for internal medicine to solve the above problems.
