Medical equipment for auripuncture and intratympanic injection

Abstract

The invention relates to medical equipment for auripuncture and intratympanic injection applied to the department of otorhinolaryngology, relates to the field of medical equipment and aims to solve the technical problem that the treatment effect on an affected part is affected by incomplete hydrops discharge due to communication of a suction channel and an injection channel of the conventional medical device in the needle position. The main technical scheme is that the medical equipment for auripuncture and intratympanic injection comprises a puncture outer tube, an injection inner tube, a plug needle, an injection device and a suction device, wherein a conical first inner wall is formed at the front end of the puncture outer tube, and a first connector is arranged at the tail end of the puncture outer tube; a conical head is arranged at the front end of the injection inner tube, the injection inner tube is inserted into the puncture outer tube, and a suction channel is formed betweenthe injection inner tube and the inner wall of the puncture outer tube; the injection inner tube can move relative to the first connector; the plug needle is in a shape adaptive to the inner wall of the injection inner tube, and can be inserted and extracted relative to the injection inner tube; the injection device is detachably connected with the injection inner tube; the suction device is connected with a port in the puncture outer tube.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical equipment for tympanic membrane puncture and intratympanic injection used in otolaryngology. Background technique [0002] Secretory otitis media is an inflammatory disease of the middle ear characterized by tympanic effusion and hearing loss. The main cause of the disease is the obstruction of the Eustachian tube, and the secretions in the tympanic cavity cannot be drained to the pharynx, forming a tympanic effusion. Tympanic effusion is mostly a mixture of transudate, exudate, and exudate. Clearing the tympanic effusion is the key to the treatment of secretory otitis media. Myringocentesis is the most commonly used treatment for otitis media, and it is simple and easy to do. Among them, in the treatment of secretory otitis media, it is necessary to insert the needle for the second time to inject medicine after the conventional puncture, sometimes forming ...
