Abstract

The invention relates to a tympanic membrane puncture and intratympanic injection medical institution applied in otolaryngology, and relates to the field of medical equipment. The technical problem that the effusion is not drained cleanly affects the treatment effect of the affected area. The technical solutions mainly adopted are: tympanic membrane puncture and intratympanic injection medical institutions, which include a puncture outer tube, an injection inner tube, a blocking needle, an injection device and a suction device. The front end of the puncture outer tube has a tapered first inner wall, and the tail end of the puncture outer tube is provided with a first connector; the front end of the injection inner tube has a tapered head, and the injection inner tube is inserted into the puncture outer tube and connected to the puncture outer tube. A suction channel is formed between the inner walls of the injection tube; the injection inner tube can move relative to the first connector; the plugging needle has a shape suitable for the inner wall of the injection inner tube, and the plugging needle can be inserted and pulled out relative to the injection inner tube; the injection device and the injection inner tube The tube is detachably connected; the suction device is connected to the port on the piercing outer tube.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical institution for tympanic membrane puncture and intratympanic injection applied in the Department of Otorhinolaryngology. 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 ...
