Problems solved by technology

[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

Embodiment Construction

[0005] As an example of the present invention, according to the principle of hydrostatics, in a closed space, the static pressure of the fluid will propagate in all directions, and its magnitude will not change. The positive pressure higher than the ambient air pressure of the human body will squeeze the pharyngeal opening of the Eustachian tube, and the normal soft tissue around the paranasal sinus opening will expand the sinus opening centrifugally. When the pressure is greater than the pharyngeal opening of the tympanic tube, the normal soft tissue around the opening of the paranasal sinus expands the sinus ostium centrifugally. The lumen is opened when the pressure exceeds the ventilatory resistance of the Eustachian tube including tissue tension closing the Eustachian tube. Experiments have confirmed that the mask pressure is consistent with the tympanic pressure at this time.

[0006] The method of the present invention is that the airway is pressurized by 4.0-8.0Kpa th...

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...
