Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a nasogastric feeding tube with an anti-misaspiration function. Background Art

[0002] Nasogastric feeding tube is suitable for patients who cannot eat orally due to illness or other reasons. It mainly involves inserting one end of the nasogastric tube into the stomach through the nasal cavity, and then using a syringe to connect the other end of the nasogastric tube to inject food, medicine and water directly into the patient's stomach, providing the patient with necessary nutrients to maintain the body's nutritional needs.

[0003] During the use of the existing nasogastric feeding tube, after the food is directly injected into the stomach through the nasogastric feeding tube, a certain amount of water is injected with a syringe to clean the inner wall of the nasogastric feeding tube. However, some food will still remain on the inner wall of the nasogastric feeding tube and cannot be cleaned up. In addition, the food in the stomach will flow back into the nasogastric feeding tube. After staying in the nasogastric feeding tube, the food will cause aspiration of the patient due to delayed gastric emptying, improper body position and improper tube position, threatening the patient's life safety. Therefore, a nasogastric feeding tube with an anti-aspiration function is needed.

[0004] According to a patent document with publication number CN218853132U, an anti-blocking nasogastric tube is disclosed, including a medicine connector, one side of the medicine connector is threadedly connected with an internal thread connector, the other side of the medicine connector is plugged with a nasogastric tube body, the upper surface of the medicine connector is provided with a branch connector, the outer wall of the medicine connector is movably connected with a flexible connecting piece, and the lower end of the flexible connecting piece is movably connected with an external thread connector. In the above scheme, air in the air pump enters the air inlet cavity through the air inlet, and then enters the anti-blocking block through the air inlet cavity. The gas in the anti-blocking block enters the expansion airbag through the air port, so that the expansion airbag blocks the nasogastric tube body to prevent Air enters the medicine outlet hole, and at the same time, the gas in the expanded airbag flows to the unblocked side of the nasogastric tube body through the air outlet. The gas blows out the blockage in the nasogastric tube body, which can effectively prevent the nasogastric tube from being blocked. However, when the above-mentioned device is in use, when the airbag is inflated, the gas flows out from the air outlet to blow out the food residue in the nasogastric tube. Since the nasogastric tube is inserted into the stomach, the nasogastric tube has a certain curvature. Blowing food residues only through the air outlet cannot blow out the food residues. Instead, the food residues may be blown into the bending part of the nasogastric tube, causing the nasogastric tube to be blocked, and there is a potential risk of accidental aspiration for the patient. Therefore, a nasogastric tube with an anti-aspiration function is proposed to solve the above problem. Utility Model Content
