Abstract

The invention relates to the field of otolaryngology medical equipment, in particular to tympanocentesis and intratympanic injection medical equipment, and mainly aims at solving the technical problem that in the prior art, medicine backflow is caused by a secondary hole formed when a needle is inserted to inject medicine for the second time after puncture and aspiration, and puncture pain of a patient is increased. According to the adopted technical scheme, the tympanocentesis and intratympanic injection medical equipment comprises a supporting frame, a fixing device, a connecting block and a tympanocentesis and intratympanic injection medical device; the tympanocentesis and intratympanic injection medical device comprises a first puncture device, a second puncture device, a suction device and an injection device, the first puncture device comprises a puncture needle and a first connector, the second puncture device comprises an injection needle and a second connector, the suction device comprises a negative pressure mechanism and a third connector, and the injection device comprises an injector and a fourth connector. The tympanocentesis and intratympanic injection medical device has a suction state and an injection state.

Description

technical field [0001] The invention relates to the technical field of ENT medical equipment, in particular to a medical equipment for tympanic membrane puncture and intratympanic injection. 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 two holes, and the ...
