A novel laryngeal mask with a temperature measuring mode

Abstract

The invention discloses a novel laryngeal mask with a temperature measuring mode, including a drain hole, an inflatable soft cover bag, a temperature probe hole, a ventilation pipe connection pipe anda ventilation pipe, wherein the drainage hole penetrates the inflatable soft cover bag, the top of the inflatable soft cover bag is provided with a vent pipe connecting tube, the temperature measureprobe hole is arranged at that top of the ventilation pipe connection pipe, a temperature measuring line channel is arranged in the ventilation pipe ventilation pipe, an inflation channel is arrange at one end of the temperature measuring line channel, a drainage channel is arranged between the inflation channel and the temperature measuring line channel, and one end of the ventilation pipe ventilation pipe is connected with the ventilation pipe through a connecting sleeve. The laryngeal mask is easy to be inserted into the airway, and when the tube is placed, the stress surface is an arc surface, which reduces the probability of scratching the mucosa, forms a sealed type closer to the airway surface, is convenient for mechanical ventilation, and can be used for measuring the temperature in the airway at any time, has strong practicability and is suitable for widespread popularization.

Description

technical field [0001] The invention relates to the technical field of medical device manufacturing, in particular to a novel laryngeal mask with a temperature measuring type. Background technique [0002] Laryngeal mask (Laryngea I Mask Airway, LMA) is an artificial airway developed by British doctor Brain in 1981 based on the anatomy of the adult throat mechanism. It was formally put into production in 1988 and applied to clinic. It was approved by the FDA for clinical use in 1991, and the number of patients using it in 2003 was greater than 100 million. [0003] According to the time and purpose of the invention of the laryngeal mask, it is divided into three categories: the first generation is ordinary laryngeal mask (KMA). The second generation is intubating laryngeal mask (LMA-Fastrach, Intubating LMA, ILMA). The third generation is reinforced laryngeal mask Mask or double tube laryngeal mask (ProSeaI-LMA). [0004] The existing first-generation, second-generation, ...

AI Technical Summary

Problems solved by technology

A series of pathophysiological changes caused by hypothermia are closely related to complications such as perioperative myocardial ischemia, coagulation disease, wound infection, and delayed recovery, which increase hospitalization costs, have a great impact on the prognosis of patients, and often lead to postoperative death rate increase
