[0002] The Eustachian tube is curved in an arch shape, with a length of 35 to 39 cm. It consists of two parts: the cartilage part and the bone part. The cartilage part is usually closed and only opens when swallowing or yawning to balance the air pressure in the middle ear and the outer ear, which is conducive to the normal vibration of the eardrum. The Eustachian tube is one of the important organs to ensure the normal function of the ear. Its function is to maintain the balance of external air pressure and regulate the air pressure in the tympanic chamber. It is also an important organ for keeping the ear clean (drainage), defense and sound production.

[0003] However, the existing Eustachian tube inflator is large in size and complicated to use. When using a single-nostril inflator, the patient needs to press the other nostril with the hand, which causes discomfort to the patient. If medicine needs to be injected into the nostril during use, the inflator needs to be taken out and put back again, which increases the patient's pain. Utility Model Content
