Description

Technical Field

[0001] The invention relates to the technical field of medical external ear cleaning, and in particular to an easy-to-use external ear cleaning device for otolaryngology. Background Art

[0002] The otolaryngology department mainly diagnoses and treats diseases related to the ear, nose, and throat. Common ear diseases include deafness, tinnitus, otosclerosis, motion sickness, blast-induced deafness, and otitis media. When these inflammations are severe or secretions block the ear canal, hearing will be seriously affected. Therefore, the external auditory canal needs to be cleaned when there is inflammation in the external auditory canal.

[0003] Based on the above, the existing external ear cleaning device has the following shortcomings:

[0004] Since the flushing fluid is drawn out through a syringe and injected into the patient's ear canal through a hose for flushing, the flushing fluid can easily enter the deep outer ear and reach the eardrum, which can easily cause discomfort. In addition, the waste fluid after flushing cannot be effectively collected. The waste fluid flowing out of the ear canal will flow along the patient's ears and neck to soak the patient's clothes, causing discomfort. Summary of the invention

[0016] 2. By sleeved the cleaning sleeve on the outside of the central axis, and when the operating tube and the central axis are combined, the rear side of the control gear at the bottom of the driving disk and the inner gear ring at the top of the inner wall of the cleaning sleeve are meshed, so that the driving disk is driven to rotate by the driving shaft at the bottom of the driving motor, and the cleaning sleeve is driven to rotate by the meshing of the control gear of the driving disk and the inner gear ring, so that the cleaning bristles and the cleaning liquid clean the earwax in the external auditory canal through the rotation of the cleaning sleeve, so as to better improve the cleaning effect of the external ear.

[0017] 3. By connecting the connecting plug and the through hole at the bottom of the operating cylinder with the connecting plug at the top of the central axis rod and the top of the inflation tube, a connection is formed, and the fixed plug rod passes through the fixed hole and is clamped in the fixed ring groove, and the top of the connecting plug is connected to the inner ring groove and passes through the return suction pipe, so that the quick-connect plug at the top of the return suction pipe and the external extraction device are matched to form a negative pressure extraction structure with the return liquid pipe connected to the bottom of the connecting plug, so that when cleaning the external ear, the cleaning liquid and earwax are extracted through the return liquid pipe inlet located at the top of the closed air bag, making the cleaning operation easier.
