Gastric tube for gastroenterology

Abstract

The invention relates to the technical field of medical instruments, in particular relates to a stomach tube used for the department of gastroenterology. The stomach tube comprises a stomach tube body. The stomach tube comprises a feeding main tube. The inner wall of one side of the feeding main tube is provided with a balloon-type decompression tube. The balloon-type decompression tube is made of double layer tubes, and an air cavity is formed between the double layer tubes. A tube orifice, stanching out of the feeding main tube, of the balloon-type decompression tube is provided with a chuck. An air inlet is formed in the upper portion of the balloon-type decompression tube, the air inlet is connected with a balloon arranged at the top of one side of the feeding main tube, and a through hole C is formed in the bottom of the balloon-type decompression tube. Protruding heads are arranged at the left side and the right side of the upper portion of the feeding main tube oppositely, grooves with threads are formed in the outer sides of the protruding heads, and clamping devices are arranged on the protruding heads. According to the stomach tube used for the department of gastroenterology, the structure is simple, installation is convenient, when air inflation is conducted on the balloon-type decompression tube, a large-diameter decompression tube is formed, when the air in the decompression tube is exhausted, the diameter of the feeding main tube cannot be influenced, using by a patient is convenient, and working efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of medical appliances, in particular to a stomach tube for gastroenterology. 【Background technique】 [0002] The traditional gastric tube is inserted directly into the stomach from the patient's nasal cavity. Then the gastric tube is fixed with adhesive tape, but due to the rejection of the foreign body by the human pharynx and spout, dryness and vomiting are prone to occur, which can easily lead to prolapse of the gastric tube, resulting in frequent and repeated re-intubation, which brings great harm to the patient. pain and discomfort. In addition, the main function of the gastric tube is to input nutrients through it, and also to perform decompression. Therefore, the general gastric tube adopts a double-tube structure with a main tube and a decompression tube in the main tube. However, the existing decompression tube is very thin and very thin. It is difficult to decompress the contents of the stomach...

AI Technical Summary

Problems solved by technology

Then the gastric tube is fixed with adhesive tape, but due to the rejection of the foreign body by the human pharynx and spout, dryness and vomiting are prone to occur, which can easily lead to prolapse of the gastric tube, resulting in frequent and repeated re-intubation, which brings great harm to the patient. pain and discomfort

In addition, the main function of the gastric tube is to input nutrients through it, and also to perform decompression. Therefore, the general gastric tube adopts a double-tube structure with a main tube and a decompression tube in the main tube. However, the existing decompression tube is very thin and very thin. It is difficult to decompress the contents of the stomach, but if the decompression tube is thickened, the feeding tube will be relatively narrowed, affecting nutrient delivery, prone to blockage, inconvenient, and low work efficiency
