Handheld uniform medicine spraying device for otolaryngology department

Abstract

The present invention relates to a handheld uniform medicine spraying device for an otolaryngology department. The device comprises a liquid storage tank and an insertion tube, a cover bin is movably mounted at the top of the liquid storage tank, the insertion tube is arranged at the top of the cover bin, and a liquid extraction tube with one end penetrating and extending into the insertion tube is fixedly connected to the inner top wall of the cover bin; a pressing mechanism is arranged on the cover bin and used for enabling liquid medicine in the liquid storage tank to flow into the insertion pipe from the liquid pumping pipe, and a plurality of rectangular movable holes are formed in the peripheral wall of the insertion pipe; and a movable pipe is further arranged in the insertion pipe, a plurality of bristles are fixedly connected to the peripheral wall of the movable pipe, and the bristles penetrate through the rectangular movable holes correspondingly. After the liquid medicine is discharged through the rectangular movable hole, the insertion pipe can be rotated to drive the bristles to rotate, the bristles adhere to the liquid medicine so that the liquid medicine can be coated in an affected part, the bristles rotate to coat the liquid medicine, the liquid medicine can be uniformly coated in the affected part, and the coating effect is better and more uniform.

Description

technical field [0001] The invention relates to the technical field of medicine spraying devices for otolaryngology, in particular to a hand-held uniform medicine spraying device for otolaryngology. Background technique [0002] "Otorhinolaryngology" is the surgery that diagnoses and treats the ear, nose, pharynx, larynx, and related head and neck areas. The emergence of microsurgery, ear neurosurgery, lateral skull base surgery, audiology and balance science, nasal endoscopic surgery, nasal neurosurgery, head and neck surgery, laryngeal microsurgery, voice and speech disorders, pediatric otolaryngology, etc. Greatly enriched the content of Otorhinolaryngology. [0003] When spraying the otolaryngology area, it needs to be extended into the ear canal, nasal cavity or throat for spraying. The existing spraying devices are all sprayed by squeezing or pressing, and the droplets are scattered, so they cannot be accurately sprayed. Spray to the affected area, and if there are u...
