Method for opening auditory tube by face-masked pressure respiration

Abstract

The invention relates to a method of face mask (or nose mask) forcing breathe opening eustachian tube which using the face mask of mouse and nose to pressurize respiratory tract more than aeration resistance of eustachian tube with non body countermeasure, and then loading the gas of face mask into middle ear cavity to prevent and cure middle ear negative pressure illness.

Description

Technical field [0001] The invention relates to a method for pressurizing a breathing Eustachian tube with a mask. Background technique [0002] At present, there are three types of passive opening methods for the Eustachian tube. One is to directly insert a catheter into the Eustachian tube opening through the anterior nasal cavity, and the high pressure created is limited to the tube opening. Tube ventilation resistance is greater, introduced by CieIand in 1741, the defect of this method is that it must be completed by a specialist. The second type is to close the front and rear nostrils and create a relatively high pressure in the whole nasal cavity. This method was advocated by Adam PoIitzer in 1863. This method has the effect of actively opening when the patient swallows. The defect of this method is that it also needs to be completed by a specialist. The third category is to pinch the nose and blow air. When shrinking the dense chest cavity, it creates a high pressure...

[0002] At present, there are three types of passive opening methods for the Eustachian tube. One is to directly insert a catheter into the Eustachian tube opening through the anterior nasal cavity, and the high pressure created is limited to the tube opening. Tube ventilation resistance is greater, introduced by CieIand in 1741, the defect of this method is that it must be completed by a specialist

The second type is to close the front and rear nostrils and create a relatively high pressure in the whole nasal cavity. It was advocated by Adam PoIitzer in 1863. This method has an active opening effect when the patient swallows. The defect of this method is that it also needs to be completed by a specialist

The third category is to pinch the nose and inflate the air. When shrinking the dense chest cavity, it creates a high pressure from the nasal cavity to the chest cavity. It was introduced by VaIsoIva in 1704. The disadvantage of this method is that it is difficult to control the pressure and time, and some people cannot complete it independently.
