Reinforced nasal gastrointestinal tube and use method thereof

Abstract

The invention discloses a reinforced nasal gastrointestinal tube and a using method thereof. The reinforced nasal gastrointestinal tube comprises a main tube, a clamping groove, a tube head assembly, a nasal plug assembly, a spring, a first balloon, a connector, a water injection tube, a second balloon and a one-way valve. The use method comprises the following steps: step 1, assembling parts; 2, inserting a main pipe; 3, fixing the main pipe; step 4, putting into use; the spring is arranged in the main tube, the main tube can be prevented from being flattened and folded after being placed into a human body, the balloon is arranged at the head of the main tube, the head of the main tube can form a heavy head by injecting substances such as normal saline, and then the main tube can be fixed through the gravity of the head and gastrointestinal motility. The main tube naturally passes through parts which are difficult to pass through such as pylorus and duodenum, so that intubation is convenient; the tube head assembly is designed, the suction hole can be prevented from being easily adsorbed and blocked by the stomach wall, the nasal plug assembly is designed, the position of the main tube can be fixed, use is more convenient, and the skin cannot be injured.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a reinforced nasogastric tube and its application method. Background technique

[0002] The role of the nasogastric tube is to extract gastric juice, or deliver nutrients to the patient's esophagus, stomach or duodenum, to provide nutrition for the patient, because the cost of nutrients in the intestine or stomach is much lower than that of intravenous injection Nutrients can reduce the economic burden of patients; however, the existing nasogastric tubes are not lined with reinforcement ribs, so the nasogastric tubes are easily crushed and folded, so that the nutrient solution cannot be delivered or the tube needs to be re-placed The situation occurs; and the front end of the existing nasogastric tube is smooth, and it is extremely difficult for the tube body to pass through the pylorus, duodenum and other parts, and it is difficult to place the tube; the existing nasogas...
