Abstract

The invention relates to a tympanum-puncture and intratympanic-injection medical device, and relates to the field of ear-nose-throat medical equipment. The tympanum-puncture and intratympanic-injection medical device mainly aims at solving the technical problems that in the prior art, medicine regurgitation is caused by a second hole formed by second needle-inserting injection after puncture liquid suction, and the puncture pain of a patient is increased. According to the technical scheme, the tympanum-puncture 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 anda second connector; the suction device comprises a negative pressure mechanism and a third connector; the injection device comprises an injector and a fourth connector. When the tympanum-puncture andintratympanic-injection medical device is in the first using state, the third connector of the suction device is connected with the second connector of the second puncture device; when the tympanum-puncture and intratympanic-injection medical device is in the second using state, the fourth connector of the injection device is connected with the second connector of the second puncture device.

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 ...
