[0002] "Otorhinolaryngology" is a surgical discipline that diagnoses and treats the ears, nose, pharynx, larynx, and related head and neck areas. An ear canal drug delivery device is required when the inside of the patient's ear canal needs to be cleaned or when medication is required due to inflammation.

[0003] Existing ear canal medication devices are mostly directly squeezed into the ear through a squeeze bottle. The amount of medicine applied needs to be controlled by controlling the force of squeezing the squeeze bottle. Since the internal space of the ear canal is small, too much medicine squeezed in at a time will directly block the ear canal and cause discomfort to the patient. Therefore, an ear canal medication device for otolaryngology care is proposed to solve the above problem. Utility Model Content

[0006] Preferably, a sealing plug is sleeved on the upper end of the medicine delivery tube, and the sealing plug and the squeeze bottle are both made of transparent soft rubber material.

[0007] Preferably, the valve port of the lower one-way valve is located at an end away from the airbag, and the valve port of the upper one-way valve is located at an end close to the push rod.

[0008] Preferably, the push rod is connected to the valve port plate of the upper one-way valve.

[0009] Preferably, a slide groove is provided on the surface of the squeeze bottle and the push rod is slidably connected to the slide groove.

[0010] Preferably, a top plate is fixed to the upper end of the side plate, and the top plate is made of transparent acrylic material.

[0011] Preferably, a filling port is fixed on the bottom of the squeeze bottle, and a sealing cap is rotatably connected to the surface of the filling port through a thread.

[0012] Compared with the related art, the ear canal medication device for ENT nursing provided by the utility model has the following features:

[0013] Beneficial effects:

[0014] The utility model fixes the amount of squeezed liquid medicine by connecting the upper one-way valve and the lower one-way valve to the air bag, so that the liquid medicine can be applied inside the ear canal without causing the ear canal to be blocked by water and causing discomfort, which is convenient for medical staff to administer medicine to the ear canal.
