Embodiment Construction

[0007] Take a multi-functional upper laryngeal ventilation mask, inject air through the air bag gas injection pipeline 14 to check that there is no air leakage as a whole, then pump out the gas of the highly airtight air bag 10, insert the insertion guide through the outlet end 6a of the esophageal drainage channel and fix it on the fixed On the handle 8, apply lubricant to the back of the mask body end 5 and the esophageal drainage channel esophageal section 6d, fix the head with the left hand, insert the guide with the right hand, and insert the multi-functional upper-laryngeal ventilation mask into the oral cavity, and wait until the insertion encounters resistance At the same time, use the right thumb to move the regulating valve on the insertion guide to adjust the up and down movement angle of the esophageal segment 6d of the esophageal drainage channel to reduce resistance. When it is inserted in place, there will be greater resistance. After auscultation, the breath sou...

Abstract

The invention provides a multifunctional on-throat vent hood, which can eminently show the advantages of an on-throat vent device. Each sub function device has the following design and functions that the composite functions of an esophagus drainage passage, a secreta collection suction passage, a sub ventilation passage and a high-tightness air bag are utilized for reaching the effects of more effectively preventing the backflow aspiration by mistake and air passage blockage; the composite functions of a special operation passage and the secreta collection suction passage can be used for sucking a great amount of bleeding at the throat part for reducing the suction by mistake and the asphyxia, and in addition, the operation view sight can be sufficiently exposed; through the design of a high-tightness air bag and a cover body side wall case, the normal ventilation can still be maintained when the head and neck parts have a greater moving range, and in addition, the vent hood is suitable for eastern and western people; through the application of a built-in guide device, the vent device has the advantages that the placing speed is higher, the accuracy is higher, in addition, the stimulation on the oropharynx and the throat parts of patients is less, and the like, so the multifunctional on-throat vent hood actually becomes a safe and efficient respiratory tract maintaining device.

Description

technical field [0001] The invention relates to a multifunctional upper-larynx ventilation mask. Background technique [0002] Endotracheal intubation is a very safe way to establish a breathing channel, but it is difficult to avoid defects such as difficult intubation for various reasons and strong stimulation of the patient during endotracheal intubation. In 1981, the British anesthesiologist Brain invented the standard laryngeal mask airway and put it on the market in 1988, and the management of the airway entered a new era. The laryngeal mask is a safe and effective upper laryngeal airway ventilation device that is less irritating to the patient, and can quickly and conveniently establish a breathing channel for the patient. With its excellent performance in dealing with common and difficult airways, the laryngeal mask has replaced endotracheal intubation as the mainstream medical device for maintaining unobstructed airways in some countries in the United States and Wes...
