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.
