AI Technical Summary
The existing anesthesia mask cannot be tightly worn on the face of patients with gastric tubes, which leads to the mask being prone to air leakage and cannot ensure the smooth progress of positive pressure ventilation. It is especially dangerous for the elderly with poor oxygen reserves and those with difficulty lifting the jaw.
An anesthesia mask specially designed for patients with gastric tubes is designed, including oxygen masks, oxygen tubes, air bags and gastric tube indwelling tunnels. The airbag is made of elastic material, and there are flaps in the gastric tube remaining in the tunnel. When the gastric tube is embedded in the tunnel, it fits with its inner surface to ensure that the mask is in close contact with the face and avoids air leakage.
By setting up gastric tube indwelling tunnels and live flaps, the problem of air leakage caused by the mask is not in close contact with the face, ensuring the smooth progress of positive pressure ventilation, and improving the stability of the anesthesia effect, especially for the elderly and other difficult groups.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to an anesthesia mask specially used for inducing anesthesia for patients with a gastric tube. Background Art
[0002] Anesthesia is a reversible functional inhibition of the central nervous system and / or peripheral nervous system produced by drugs or other methods. The main characteristic of this inhibition is the loss of sensation, especially pain. Anesthesia mask is a medical device used to give patients general anesthesia. At present, when anesthetizing patients, medical staff will use anesthesia masks, but the existing anesthesia masks are simple in structure, usually consisting of a mask with an adapter and a connecting tube, with a single function. For patients with gastrointestinal nutrition tubes, it is impossible to wear the mask tightly on the patient's face. Therefore, the mask is prone to leaking during anesthesia induction, and positive pressure ventilation cannot be ensured to proceed smoothly. This not only reduces the effect of anesthesia, but also is more dangerous for the elderly with poor oxygen reserves and those who have difficulty lifting their jaws. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide an anesthesia mask specially used for inducing anesthesia for patients with a gastric tube.
[0004] In order to solve the above technical problems, the technical solution provided by the utility model is an anesthesia mask specially used for inducing anesthesia for patients with gastric tubes: it includes an oxygen mask and an oxygen tube arranged on the oxygen mask, an inflatable bag is provided on the bottom edge of the oxygen mask, a gastric tube indwelling tunnel is provided on the left or right end of the lower side of the inflatable bag, and valves are symmetrically provided on both sides along the middle of the lower side of the gastric tube indwelling tunnel, the inflatable bag is made of elastic material, and the valve is made of elastic material. When the gastric tube is embedded in the gastric tube indwelling tunnel, the gastric tube fits the inner surface of the gastric tube indwelling tunnel and the inner surface of the valve.
[0005] The advantages of the utility model compared with the prior art are: the utility model arranges a gastric tube indwelling tunnel at the lower part of the oxygen mask, so the gastric tube can be easily embedded therein, the operation is convenient, the oxygen mask can be better fitted to the face, the comfort is good, and it is not easy to shift; and two valves are arranged at the lower end of the gastric tube indwelling tunnel, so that it can be ensured that the gastric tube can be embedded and can limit the gastric tube to a certain extent after embedding, and can also avoid leaving a gap between the gastric tube indwelling tunnel and the face during use, thereby avoiding air leakage and ensuring smooth positive pressure ventilation; the structure is simple and reasonable, can be manufactured, and has good practicality.
