Description

A gastric air pressure monitoring and inflation device

Technical Field

The utility model relates to a medical air pressure monitoring and inflation device, in particular to an intragastric air pressure monitoring and inflation device.

Background technique

CT-guided percutaneous gastrostomy is a minimally invasive medical technology used to solve a variety of gastrointestinal problems. It can be used to treat gastric emptying disorders, relieve nausea and vomiting symptoms in cancer patients, manage emptying needs after gastric surgery, conduct experimental treatments, or in the pre- and post-operative preparation stage. Gastric cavity inflation is a very important part of this technology. Proper gastric inflation makes the gastric wall fit with the anterior abdominal wall, making it easier to determine the location of the fistula.

At present, gastric inflation generally adopts a three-way valve connected to a medical syringe for inflation. According to the different switch positions of the three-way valve, the whole inflation process is broken down into the following steps: 1. Adjust the three-way valve: the three-way valve connects the medical syringe with the outside air; 2. Vacuum: pull the syringe piston backward and fill the syringe with gas; 3. Adjust the three-way valve: the three-way valve connects the medical syringe barrel and the gastric tube; 4. Inflate: push the syringe piston forward, and the gas in the syringe is injected into the gastric cavity through the gastric tube.

The above-mentioned inflation process relies on the switching of the three-way valve to achieve the purpose of distributing the gas flow direction. The entire inflation process requires repeated switching of the three-way valve, which will have the following three problems: 1. Low inflation efficiency: The entire gastric cavity inflation process requires frequent switching of the three-way valve, and the inflation process is not continuous enough; 2. Blind operation during the inflation process: The entire inflation process completely relies on the experience of the operating physician, and real-time monitoring of the intragastric air pressure cannot be achieved, which poses certain risks; 3. The gastric filling condition cannot be obtained in real time: The specific filling condition of the stomach is not clear during the operation, and it relies entirely on CT tomography, but the latter lacks real-time performance.

Therefore, the applicant proposed the present utility model.

Summary of the invention

The plug is connected to a medical plug, the second outlet of the medical tee is sealed and docked with one end of the medical delivery tube three, the other end of the medical delivery tube three is sealed and docked with the valve inlet of the medical one-way valve two, the valve core of the medical one-way valve two is always opened only during the process of exhausting the medical syringe, the valve outlet of the medical one-way valve two is sealed and docked with one end of the medical delivery tube four, the other end of the medical delivery tube four is sealed and docked with the medical gastric tube interface, a medical gastric tube interface cap is detachably sealed and sleeved on the medical gastric tube interface, and a medical pressure gauge for real-time detection of the air pressure value in the tube is provided on the medical delivery tube four.

The utility model provides a gastric air pressure monitoring and inflation device, in which two medical one-way valves are used to realize continuous inflation of the gastric cavity by a medical syringe. The specific operation and principle are as follows: first, remove the medical gastric tube interface cap originally on the medical gastric tube interface, and seal the medical gastric tube interface with the gastric tube; second, remove the medical plug originally at the valve inlet of the medical one-way valve one; third, pull the piston core rod of the medical syringe backward, which is the process of the medical syringe inhaling air. At this time, the valve core of the medical one-way valve one is always open, and the outside air passes through the medical one-way valve one, the medical delivery tube two, the first outlet and the inlet of the medical three-way, and the medical delivery tube one, and then enters the syringe through the nipple on the syringe of the medical syringe for accumulation; finally, push the piston core rod of the syringe forward, which is the process of the medical syringe exhausting air. The air originally gathered in the syringe passes through the medical delivery tube one, the inlet and the second outlet of the medical three-way, the medical delivery tube three, the medical one-way valve two and the medical delivery tube four, and then is injected into the stomach cavity through the gastric tube.
