Abstract

The invention relates to the field of otolaryngological medical equipment, in particular to a medical device for tympanocentesis and intratympanic injection and mainly aims to solve the technical problem of puncture pain intensification caused by medicine backflow resulted from two pores formed in secondary needle insertion for medicine injection after paracentesis in the prior art. The technical scheme mainly includes that the medical device for tympanocentesis and intratympanic injection 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 second connector; the injection device comprises an injector and a fourth connector. When the medical device is in a first use state, the third connector of the suction device is connected with the second connector of the second puncture device. When the medical device is in a second use 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 ear, nose and throat medical equipment, in particular to a medical device 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 h...
