Cerumen rinser

Abstract

The present invention relates to the technical field of medical devices, in particular to a cerumen flusher, which includes a cylinder with a double-layer structure, which includes an outer cylinder and an inner cylinder, and an airtight seal is formed between the outer cylinder and the inner cylinder. The cavity is equipped with a heating device, a temperature sensor and a controller; the two ends of the cylinder are respectively provided with a first opening and a second opening, and both the first opening and the second opening make the inner cavity of the inner cylinder communicate with the outside world. The first opening is connected with a conduit, and one end of the conduit is located outside the cylinder, and is connected with a hose; a piston and a push rod motor are installed in the inner cavity of the inner cylinder, and the piston is slidingly connected with the inner cylinder, and the inner cavity of the inner cylinder is divided into Two chambers that are not connected to each other. The two chambers correspond to the first opening and the second opening one by one. The push rod motor is installed in the chamber where the second opening is located and connected to the piston. The push rod motor drives the piston along the inner cylinder. The wall slides. The invention has a simple, complete and compact structure and can reduce the damage to the external auditory canal.

Description

【Technical field】 [0001] The invention relates to the technical field of medical devices, in particular to a cerumen rinser. 【Background technique】 [0002] At present, when treating diseases in the ear canal, first use an ear speculum to observe the situation in the ear. According to the observation, if it is necessary to rinse the cerumen in the ear canal, it should be done with another special ear canal irrigation device. . The external auditory canal is a curved duct from the outer ear door to the tympanic membrane, with a total length of about 2.1-2.5cm. It is one of the high-incidence parts of the human body. It is mainly caused by various inflammations. The clinical manifestations are ear itching, ear discomfort, congestion, swelling, and watery appearance. secretions etc. Hearing can be severely affected when the inflammation is severe or when the ear canal is blocked by secretions. Due to the small size of the ear canal and the sensitivity of the tympanic membran...

Problems solved by technology

However, sometimes children will move around at will, or the patient will move around when the hard needle pricks the patient, and because the needle is hard, it will also hurt the patient's ear canal, especially for children.

Furthermore, the existing cerumen flushing device is not highly automated or has a complex structure, which is inconvenient to use. Therefore, it is necessary to improve the existing flushing device to facilitate people's use.
