Instrument for external auditory canal observation and earwax cleaning

Abstract

The invention discloses an instrument for external auditory canal observation and earwax cleaning. The instrument comprises a cleaning tube, a piezoelectric ceramic plate, a connecting tube, a reflecting mirror, a transparent lens, a rubber bladder, an LED lamp and an end cap. The cleaning tube comprises a hollow transparent tube body, and the piezoelectric ceramic plate is arranged at the end of the cleaning tube. The rubber bladder is arranged on the bottom surface of the connecting tube, an observation window of the transparent lens is arranged on the side face of the connecting tube, and the reflecting mirror is arranged inside the connecting tube. The reflecting mirror is a cylindrical solid glass column with a small-size through hole, the end of the reflecting mirror is designed as a slope with a 45-degree inclination angle, and silver light powder is arranged on the slope. The end cap is arranged at the end of the connecting tube and used for fixing the LED lamp. Small-amplitude ultrasonic vibration is formed on the cleaning tube by the aid of excitation of piezoelectric ceramics to be used for peeling earwax, and shed earwax is removed by the aid of atmospheric negative pressure. The instrument is simple in structure and convenient to operate, and has wide application prospects in the medical field.

Description

technical field [0001] The invention relates to an instrument for observing the external auditory canal and cleaning cerumen, which belongs to the medical field. Background technique [0002] Cerumen is a light yellow, sometimes viscous substance secreted by the cerumen glands of the skin of the external auditory canal, commonly known as earwax. Cerumen tends to dry out when exposed to air, forming small flakes. If too much cerumen blocks the external auditory canal, it may affect hearing or cause other symptoms, so it should be removed as soon as possible. Traditional ear picks are often made of relatively hard metal or plastic, coupled with incorrect angles and unknown depths, it is easy to pierce the thin skin and hair follicles of the external auditory canal, resulting in otitis externa, or pushing earwax deep into the ear. The inflamed ear canal epidermis often loses the ability to automatically remove earwax, resulting in more and more earwax accumulation. Contents...
