Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a gastrointestinal decompression device. Background Art

[0002] As we all know, gastrointestinal decompression is often used in gastroenterology. Gastrointestinal decompression utilizes the principles of negative pressure suction and siphoning to insert a gastric tube through the oral or nasal cavity. The tube then sucks out gas and fluid accumulated in the gastrointestinal tract. This can reduce the pressure and expansion of the gastrointestinal tract in patients with gastrointestinal obstruction, prevent gastrointestinal contents from leaking into the abdominal cavity through the rupture in patients with gastrointestinal perforation, and facilitate the healing of the anastomosis after gastrointestinal anastomosis. However, one end of the gastric tube is usually connected to a pressure plate. If there is too much fluid inside the pressure plate, the negative pressure suction capacity of the gastric tube will be greatly reduced. In addition, during the replacement of the pressure plate, the fluid inside the gastric tube can easily flow out of the gastric tube, making the bed sheets near the gastric tube easily contaminated. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art that when there is too much liquid inside the pressure plate, the negative pressure suction ability of the gastric tube will be greatly reduced, and during the process of replacing the pressure plate, the liquid inside the gastric tube will easily flow out along the gastric tube, making the bed sheets near the gastric tube easily contaminated. A gastrointestinal decompression device is proposed to solve the shortcomings of the prior art that when there is too much liquid inside the pressure plate, the negative pressure suction ability of the gastric tube will be greatly reduced, and during the process of replacing the pressure plate, the liquid inside the gastric tube will easily flow out along the gastric tube, making the bed sheets near the gastric tube easily contaminated.

[0010] Preferably, a handle is provided on one side of the collection tank.

[0011] Preferably, a retaining ring is provided in the housing.

[0012] The gastrointestinal decompression device proposed by the present invention has the following beneficial effects: when medical staff replace the collection canister, the weight block will squeeze the connecting tube, so that the bottom of the weight block contacts the top of the discharge tube, so that the discharge hole at the discharge tube and the discharge hole at the connecting tube are in a misaligned state, so that the liquid inside the shell will not continue to be discharged through the connecting tube, thereby making the area around the device cleaner; and when the negative pressure component inside the shell is working, the inside of the shell is still in a negative pressure state, so that during the replacement of the collection canister, the negative pressure inside the shell will continue to absorb gastric fluid into the gastric tube.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figure 1-6 The top of the shell 3 is provided with a groove 11, and the bottom of the shell 3 is provided with a groove 12. The bottom of the shell 3 is provided with a groove 13, and the bottom of the shell 3 is provided with a groove 14. The groove 14 is provided with a groove 16. The bottom of the shell 3 is provided with a groove 17. The bottom of the shell 3 is provided with a groove 18.

[0022] After the patient's gastric tube is connected to the connecting tube 4 on the device, the negative pressure component 18 is started, so that the cavity inside the shell 3 is in a negative pressure state, so that the shell 3 will absorb gastric fluid from the gastric tube, etc., so that the patient's stomach and intestines are in a decompression state, and the liquid inside the shell 3 will reach the collection tank 9 through the discharge hole 8 at the discharge pipe 5 and the connecting pipe 6 for collection, so that the device can collect gastric fluid in large capacity, thereby reducing the number of times medical staff discharge and replace the gastric fluid. When the collecting tank 9 is removed, the weight block 7 will squeeze the connecting pipe 6, so that the bottom of the weight block 7 contacts the top of the discharge pipe 5, so that the discharge hole 8 at the discharge pipe 5 and the discharge hole 8 at the connecting pipe are in a misaligned state, so that when the negative pressure component 18 is working, the inside of the shell 3 is still in a negative pressure state, so that during the replacement of the collecting tank 9, the liquid inside the shell 3 will not continue to be discharged through the connecting pipe 6, and the negative pressure inside the shell 3 will continue to absorb gastric fluid from the gastric tube.

[0023] Example 2: Based on Example 1, optimization is performed, referring to Figure 1-6 A card slot 14 is provided on one side of the top of the connecting seat 10, and a card block 15 is installed on one side of the bottom of the connecting plate 12. In one state, the card slot 14 cooperates with the card block 15, and the card slot 14 is not connected to the groove 11. The inner wall of the groove 11 is provided with a wear-resistant coating, a handle 16 is provided on one side of the collection tank 9, and a retaining ring 17 is provided in the shell 3.

[0024] The wear-resistant coating is formed by nitriding treatment, so that the mechanical properties of the connecting seat 10 at the groove 11 are improved, the groove 11 of the connecting seat 10 is more wear-resistant, and the service life of the connecting seat 10 is increased.

[0025] The provided slot 14 and the block 15 cooperate to squeeze the connecting plate 12 onto the connecting seat 10, putting the elastic member 13 in a squeezed state. Combined with the handle 16, it is more convenient to take the collection tank 9. The provided retaining ring 17 prevents the liquid in the connecting pipe 4 from reaching the negative pressure component 18.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
