Medical flushing device for external auditory canal

Abstract

The invention discloses a medical flushing device for an external auditory canal and aims to provide an electric medical flushing device for the external auditory canal, and the electric medical flushing device is novel in structure, convenient to use, comfortable and safe and has multiple operation positions. The medical flushing device comprises a flushing control device container, a flusher, a hose, a negative-pressure input control pipeline and an electrical device. The improvement is made for defects of uncontrollable temperature, pressure and angle of flushing liquid and unrecyclable mixed flushing liquid in the prior art. The key points of the technical scheme solving problems are as follows: the flushing liquid is conveyed by adopting a direct-current micro-motor pump, and optimal flushing force is realized through voltage regulation control of a direct-current silicon controlled rectifier on rotational speed of the motor and the pump; a preheating cavity is formed, so that automatic temperature control of the flushing liquid is realized; a negative-pressure cavity is formed, so that recycling of the mixed flushing liquid is realized; a liquid collection cavity is formed and the flushing liquid is used for flushing the wall of the external auditory canal at an angle of 90 degrees from an inner chamfer at an outer pipe end, so that a flushing treatment effect is improved. The medical flushing device is suitable for clinical application of cerumen in the external auditory canal, foreign matters in the external auditory canal, otitis externa and otitis media.

Description

technical field [0001] The invention relates to a medical external auditory canal irrigation device. Background technique [0002] At present, the number of patients with ear diseases is increasing in my country. Hospitals still use simple and primitive irrigation methods and utensils for the treatment of patients with external auditory canal secretions, foreign bodies, and cerumen. Uncontrollable and low curative effect and unrecoverable defects, even the direct flushing of the tympanic membrane with the flushing fluid may cause potential harm to the patient. Therefore, the existing technology should be improved, and a safe, comfortable and effective flushing device that can overcome the defects of the prior art should be developed. The external auditory canal irrigation device is used for clinical purposes. Contents of the invention [0003] The purpose of the present invention is designed to overcome the deficiencies of the prior art, and is accomplished through the foll...
