Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable gastrointestinal decompressor. Background Art

[0002] A gastrointestinal decompression device is a medical device that primarily utilizes the principles of negative pressure suction and siphoning to remove gas and fluid accumulated in the gastrointestinal tract through a gastric tube, thereby reducing pressure within the GI tract, improving blood circulation within the gastrointestinal wall, and promoting the recovery of digestive function. Gastric fluid samples are typically collected for subsequent laboratory analysis. Currently, during treatment, a negative pressure device is required to completely aspirate the gastric fluid and then collect samples for testing. This is time-consuming, and squeezing the negative pressure device to release the gastric fluid can easily splash onto medical staff and patients, making it difficult to clean up.

DETAILED DESCRIPTION

[0019] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application, as follows.

[0020] Please refer to Figure 1 and Figure 2 The utility model provides a disposable gastrointestinal decompression device, including an upper cover 100, an outer tube 200, a lower cover 300, a covered liquid / gas outlet 400, a fixing belt 500, a spring 600, a valve three-way pipe 700, a liquid inlet 800, an inner tube 900 and a drainage tube 1100; the fixing belt 500 is arranged at the center above the upper cover 100; the outer tube 200 is arranged between the upper cover 100 and the lower cover 300; the upper cover 100 and the lower cover 300 are connected by a spring 600 in the middle; the inner tube 900 is arranged outside the spring 600; the liquid inlet 800 is arranged above the upper cover 100; the covered liquid / gas outlet 400 is arranged at the lower end of the outer tube 200; the drainage tube 1100 is connected to the liquid inlet 800; the valve three-way pipe 700 is arranged on the drainage tube 1100.

[0021] Preferably, the outer tube 200 and the inner tube 900 are made of PVC material. The material is relatively soft and tough, which can ensure that gastric juice does not leak out and is convenient for squeezing the gastrointestinal decompression device.

[0022] Preferably, the upper cover 100 and the lower cover 300 can be buckled together, saving space and being more convenient to carry.

[0023] Preferably, the outer cylinder 200 is provided with a scale, so that medical staff can observe the amount of gastric juice more clearly and intuitively.

[0024] Preferably, the valve tee 700 includes a tee 801 , a knob 802 , a valve tube 803 and a cover 804 .

[0025] Preferably, both ends of the valve tube 803 of the valve tee 700 are provided with threads.

[0026] The side hole of the tee pipe 801 of the valve tee pipe 700 is provided with an internal thread, and the inner side of the cover 804 is also provided with an internal thread.

[0027] The threads at both ends of the valve tube 803 of the valve tee 700 match the internal threads of the tee 801 and the cover 804 .

[0028] The lower end of the knob 802 is hollow and is vertically arranged in the middle of the valve tube 803. The part of the knob 802 placed in the valve tube 803 is provided with two identical circular holes in front and back, and the diameter of the circular holes is the same as the inner diameter of the valve tube 803.

[0029] When extracting gastric juice, first open the drainage / gas port 400, and by squeezing the upper cover 100 and the lower cover 300, the spring 600 is contracted, driving the air in the gastrointestinal decompression device to be discharged, so that the gastrointestinal decompression device is in a negative pressure state, and then close the drainage / gas port 400. Then the medical staff inserts one end of the sterilized gastric tube into the stomach through the nose or mouth, and connects the other end to one end of the valve three-way pipe 700. Then release the gastrointestinal decompression device to make the spring 600 rebound. The gastric juice is attracted by the negative pressure and extracted from the stomach through the gastric tube into the gastrointestinal decompression device. At this time, turn the knob 802 on the valve three-way pipe 700 to allow the gastric juice to pass through the round hole The gastric juice flows out through the valve tube 803, the cover 804 is opened, and the gastric juice is sampled. After the sampling is completed, the knob 802 is turned back, the cover 804 is closed, and a certain amount of gastric juice is sampled for inspection. After the gastric juice is extracted, the amount of gastric juice is observed by the scale, and it is added to the gastric juice sampled before and recorded. Then the covered drain / air vent 400 at the lower end of the outer cylinder 200 is opened to discharge the gastric juice to prevent the gastric juice from splashing. At the same time, the fixing belt 500 above the upper cover 100 can be more conveniently fixed to the patient's pillow to prevent the gastrointestinal decompression device from falling off due to factors such as the patient's bed head being too high or turning over.
