Two-chamber larynx cover

Abstract

The invention belongs to the field of medical devices and provides a double-cavity laryngeal mask. The double-cavity laryngeal mask comprises an aeration conduit, an inflatable hood and an air duct. A stainless steel wire spring is inserted in the pipe wall of the aeration conduit; the aeration conduit is connected with a feeding conduit in parallel and can be fixedly connected with the inflatable hood; the end of the air duct is connected to a one-way valve through an indicating gas bubble; and the inflatable hood is connected with an outer bow-shaped air bag base into a whole by a hollow cylindrical air bag. The invention has the advantages of reasonable structure, soft and proper pipe body and low manufacturing cost; the stainless steel wire spring can enhance the strength of the pipe wall of the aeration conduit, so that the aeration conduit is bent along the arbitrary direction or can still keep in the smooth state when being bitten by patients and can be placed in the laryngeal pharynges of the patients safely and quickly; and the aeration conduit has small stimulation to the patients and small mechanical obstruction to a respiratory passage when being placed, therefore, the double-cavity laryngeal mask not only can be used for the patients suffering from conventional operation, but also can be used for the situation that trachea cannulas meet difficulties as an emergent air duct processing device or the patients whose cardio-pulmonary resuscitation needs first aid, and provides great convenience for popularization and use in the medical clinic.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a double-chamber laryngeal mask with simple structure, low cost and soft and suitable tube body. Background technique [0002] The laryngeal mask is widely used in medicine as a medical device used to maintain the patient's breathing during anesthesia and rescue of critically ill patients. However, the existing laryngeal mask has the following deficiencies in structure: 1. The effectiveness of the seal Not enough, sometimes not enough to achieve positive pressure ventilation; Second, it cannot solve the problem of reflux of the contents in the patient's stomach, and at the same time it will affect the comfort of the patient's throat; Third, it cannot be used at one time, and there are concerns about hygienic use and operation. Also not simple enough, can't keep unobstructed state all the time, four, the structure is complex, it is difficult to really achieve the most si...

[0002] The laryngeal mask is widely used in medicine as a medical device used to maintain the patient's breathing during anesthesia and rescue of critically ill patients. However, the existing laryngeal mask has the following deficiencies in structure: 1. The effectiveness of the seal Not enough, sometimes not enough to achieve positive pressure ventilation; Second, it cannot solve the problem of reflux of the contents in the patient's stomach, and at the same time it will affect the comfort of the patient's throat; Third, it cannot be used at one time, and there are concerns about hygienic use and operation. Also not simple enough, can't keep unobstructed state all the time, four, the structure is complex, it is difficult to really achieve the most simplified part, and the production cost is still higher, as Chinese patent 200610129405.0 discloses a kind of disposable silicon plastic laryngeal mask, the laryngeal mask of this type The mask is firmly connected and safe to use, but the price of the laryngeal mask is relatively expensive, which brings a lot of inconvenience in use, and it is still difficult to apply and promote it in a large area
