Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an ear pressure auxiliary training device. Background Art

[0002] Due to rapid changes in potential energy, such as those experienced in airplanes, diving, high-rise sightseeing elevators, and high-altitude work, as well as primary Eustachian tube disorders, pressure differentials between the inside and outside of the eardrum can cause intense and persistent ear fullness, tinnitus, hearing loss, and even ear pain in some people, severely impacting their quality of life. These patients often require self-training to restore pressure inside and outside the eardrum. The most commonly used method is the "nose pinching and inflating" technique, in which the patient pinches the nostrils with their fingers, closes the anterior nostrils, holds their breath, and blows forcefully to create positive pressure inside the eardrum, causing it to bulge outward. Alternatively, the patient covers their ears with their palms, then quickly releases them, creating a transient negative pressure inside the ear canal, causing it to bulge inward. However, these treatments are often imprecise and ineffective, sometimes causing discomfort and discomfort for the patient. Furthermore, many patients struggle to adhere to these methods, resulting in suboptimal results. Utility Model Content

The inner side of the earmuffs 2 is provided with an ear cavity 3, and the edge of the cavity opening of the ear cavity 3 is provided with a sponge layer 11. When the earmuffs are put on the patient's ear, the sponge layer is in contact with the ear, which makes the patient feel more comfortable. The bottom of the ear cavity 3 is provided with a fixed channel 4 connected to the outside, and the patient's ear is in the ear cavity; a filling and suction tube 5 is fixed in the fixed channel 4, and a cavity 6 is provided in the filling and suction tube 5.

[0020] The elastic piston 8 includes a rod body 12 disposed in the hollow chamber 6, with a push plate 13 fixed to the inner end of the rod body 12; the air pressure chamber 9 is composed of the push plate 13 and the hollow chamber 6, and the inner end of the push plate 13 conflicts with the movable end of the shift adjustment assembly 10; the outer end of the rod body 12 has a push button 14 located outside the filling and suction tube 5, and a spring 15 is connected between the end of the filling and suction tube 5 and the push button 14, which mainly plays the role of resetting the rod body; the patient presses the push button at one end of the rod body to move the rod body inward, pushing the air in the air pressure chamber into the ear canal, increasing the air pressure in the ear canal, and releasing the push end, the rod body resets under the action of the spring, the air pressure chamber expands, and the air in the ear canal is extracted, reducing the air pressure in the ear canal. The outer end surface of the push button 14 is a semi-arc structure, which improves the feel of pressing and improves the stability when pressing.
