Description

Gastric juice collector

Technical Field

The utility model belongs to the technical field of medical equipment manufacturing, and particularly relates to a gastric juice collector matched with a gastroscope for use.

Background

Gastric juice analysis can understand the secretion function, emptying condition, bleeding and the like of the stomach, but has been abandoned gradually since the wide popularization of gastroscopes. However, in clinical and scientific work, it is still necessary to collect gastric juice from patients for analysis, to assist diagnosis of diseases or to conduct scientific research. The traditional collection method is to independently use a gastric tube to extract gastric juice, and during operation, the gastric tube is fed into the stomach from the nose or mouth of a patient to extract gastric juice, and the extracted gastric juice is input into a liquid collecting bag. The method has the technical defects that the operation is complicated, the gastric juice is difficult to extract when the amount of the gastric juice is small, and the patient is painful and difficult to accept, so the method is not easy to develop. How to improve the traditional collection method and the corresponding tools thereof so as to smoothly extract gastric juice and relieve the pain of patients is a problem which is continuously researched in the field in recent years.

Disclosure of Invention

The utility model provides a gastric juice collector, which aims to be matched with a new gastric juice collecting method, thereby overcoming the technical defects of more complicated operation, difficulty in extracting gastric juice when the amount of gastric juice is small, more pain of a patient and difficulty in acceptance in the prior art. The purpose is realized by the following technical scheme:

the utility model provides a gastric juice collector, includes that the bottleneck of stock solution bottle, feed liquor pipe, stock solution bottle is equipped with sealed lid, and in the feed liquor pipe ran through sealed lid and extended to the stock solution bottle, still included the negative pressure pipe, the negative pressure pipe ran through sealed lid and extended to the stock solution bottle in, feed liquor pipe outer lane and gastroscope suction connector phase-match.

The basic technical concept of the utility model is as follows: when the gastroscope examination is performed on a patient, the pumped gastric juice is pumped into the gastric juice collector by the way of the gastroscope clamp channel, so that the outer opening of the liquid inlet pipe of the gastric juice collector is required to be matched with the gastroscope suction connector. The traditional gastric juice collector or the liquid collecting bag can not meet the requirement due to different structures. In addition, the utility model can extract gastric juice of patient without need of extracting gastric juice for patient, so it can reduce pain of patient.

On the basis of the above technical solutions, the following technical means can be added to the present invention to better or more specifically solve the technical problems to be solved by the present invention:

the gastroscope suction connector is characterized by also comprising a hose, wherein the hose is used for hermetically communicating the outer opening of the liquid inlet pipe with the gastroscope suction connector.

Furthermore, the liquid storage bottle is provided with scale marks which can indicate the volume of gastric juice.

Furthermore, the outer opening of the negative pressure tube is in a conical shape and can be hermetically communicated with a suction tube of a negative pressure device matched with the gastroscope system.

Further, the surface of the hose is provided with a carbon fiber film layer.

Detailed Description

The technical scheme of the utility model is described in detail by one embodiment and the accompanying drawings.

As shown in fig. 1, a gastric juice collector comprises a liquid storage bottle 1, a sealing cover 2, a liquid inlet pipe 3, a negative pressure pipe 4 and a hose 5, wherein the sealing cover 2 is hermetically covered at the bottle mouth of the liquid storage bottle 1, an inner mouth 301 of the liquid inlet pipe and an inner mouth 401 of the negative pressure pipe penetrate through the sealing cover 2 and extend into the liquid storage bottle 1, an outer mouth 302 of the liquid inlet pipe is hermetically communicated with a gastroscope suction joint (also called as a suction nozzle, not shown in the figure) through the hose 5, and an outer mouth 402 of the negative pressure pipe is hermetically communicated with a negative pressure device suction pipe (not shown in the figure) matched with a gastroscope system, and has the function of forming negative pressure in the liquid storage bottle 1.

As shown in fig. 2, in the present embodiment, the tube wall of the hose 5 has a double structure, that is, the surface of the hose 5 is provided with a carbon fiber film layer. Specifically, the inner layer 501 of the tube wall of the hose 5 is made of silica gel and has a thickness of 0.15mm, and the outer layer 502 of the tube wall of the hose 5 is a carbon fiber film layer and has a thickness of 0.05 mm. Carbon fiber film layer elasticity is good, and intensity is big, and is harmless to the human body, sets up the intensity of carbon fiber film layer multiplicable hose 5, is convenient for take out the liquid storage bottle 1 with the gastric juice.

The structural features of one embodiment of the present invention are described in detail above with reference to the accompanying drawings, and the method of use thereof is further described below:

endoscope doctor operates gastroscope inserting portion and inserts patient's stomach cavity, and the gastroscope tip is close to the mucus paste under the direct vision (gastric acid gathers in the mucus paste, generally is located the big curved side in the fundus of stomach), presses the attraction button on the gastroscope operating portion and can starts the negative pressure, and the mucus paste gastric juice enters into the pliers pipeline export of gastroscope tip because the suction effect of negative pressure, behind the pliers pipeline of flowing through, enters into after the suction joint outflow of following the pliers pipeline in the feed liquor pipe 3 to flow into by feed liquor intraductal mouthful 301 in the stock solution bottle 1. After the gastric juice is collected, the sealing cover 2 on the liquid storage bottle 1 can be taken down, and the aseptic outer cover is covered for clinical analysis or scientific research. The operation is simple and quick, and is convenient for the operation of an endoscope doctor.
