Abstract

The invention discloses an auripuncture and intratympanic injection medical device and relates to the field of ear-nose-throat medical equipment and mainly aims to solve the technical problems in the prior art that two holes are formed by secondary needle-inserting drug injection after tapping, and consequently drug regurgitation happens and the puncture pain of a patient is increased. Main technical scheme is as follows: the auripuncture and intratympanic injection medical device comprises a first puncture device, a second puncture device, a suction device and an injection device, wherein the first puncture device comprises a puncture needle and a first connecting head; the second puncture device comprises an injection needle and a second connecting head; the suction device comprises a negative-pressure mechanism and a third connecting head; the injection device comprises an injector and a fourth connecting head. When the medical device disclosed by the invention is in a first service state, the third connecting head of the suction device is connected with the second connecting head of the second puncture device; when the medical device disclosed by the invention is in a second service state, the fourth connecting head of the injection device is connected with the second connecting head 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...
