Special anesthetic mask for gastrointestinal decompression patient

Abstract

The invention discloses a special anesthetic mask for a gastrointestinal decompression patient. The special anesthetic mask is technically characterized by comprising a mask body, a gastrointestinal decompression tube, a clamping air bag, a breathing circuit interface, a facial air cushion and a connecting tube, wherein the breathing circuit interface and a fixing port are formed in the mask body,the clamping air bag is inlaid in the fixing port, the facial air cushion is arranged on the edge of the mask body and communicates with the clamping air bag through the connecting tube, and the clamping air bag is set as follows: when the clamping air bag expands, the gastrointestinal decompression tube is clamped and fixed by the clamping air bag, and when the clamping air bag contracts, the gastrointestinal decompression tube can move in the length direction of the tube body. When the mask of the gastrointestinal decompression patient is ventilated, air leakage caused by the gastrointestinal decompression tube is avoided, the gastrointestinal decompression can be prevented from degenerating under pressure, and risks of gastric content reflux and aspiration in the induction period of mask ventilation are reduced. Besides, inserting depth of the gastrointestinal decompression tube can be adjusted by adjusting the expanding degree of the clamping air bag, and meanwhile, the clamping air bag can be suitable for clamping the gastrointestinal decompression tubes with different sizes.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a special anesthesia mask for patients with gastrointestinal decompression. Background technique [0002] Gastrointestinal decompression refers to inserting a gastric tube into the patient's stomach from the mouth or nasal cavity, and using the principle of negative pressure suction and siphon to suck out the gas and liquid accumulated in the gastrointestinal tract through the gastric tube, which can reduce the pressure and pressure in the gastrointestinal tract. The degree of expansion is often used in emergency general anesthesia patients with full stomach, gastric dilatation, intestinal obstruction, gastrointestinal perforation repair or partial resection, and patients after biliary tract or pancreatic surgery. In general anesthesia, gastrointestinal decompression greatly reduces the incidence of gastric regurgitation and aspiration during anesthesia induction. [0003] Patient...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: 1. There is an independent inflation and deflation valve at the socket of the sealing fastener, which needs to be inflated and deflated separately during use, and the operation is cumbersome; 2. The design of the socket of the sealing fastener is complicated, and the manufacturing process requires high requirements. , the production composition is high, which increases the manufacturing cost of the mask

The disadvantages are: 1. Rubber rings are used to fasten and compress both ends of the airbag, which is prone to air leakage; 2. The inner diameter of the indwelling tube hole matches the outer diameter of the indwelling nasogastric tube, which is suitable for a single type and size of nasogastric tube, and is not applicable Suitable for various types of nasogastric tubes; 3 After the device fixes the gastric tube, the length of the gastric tube is not easy to adjust
