Detailed Description
For the convenience of understanding, the technical solution of the present invention is further described in detail below by way of embodiments with reference to the accompanying drawings:
as shown in figures 1-4, a device for injecting surface anesthetic at the nasal and throat comprises a body 1, an injection tube 2, a medicine storage tank 3, a sealing plug rod 4 and a medicine extruding thin rod 5.
A medicine storage tank 3 is arranged in the body 1.
The front end of the medicine storage tank 3 is provided with a medicine spraying pipe 2, the front end of the medicine spraying pipe 2 is provided with a medicine spraying head 19, and the medicine spraying head 19 is provided with a plurality of medicine spraying holes 14.
A medicine inlet hole is arranged on the medicine storage tank 3, and a medicine inlet sealing plug 15 is arranged at the medicine inlet hole of the medicine storage tank 3. The medicine storage tank 3 is a small-measuring medicine storage tank, and preferably adopts a five-milliliter medicine storage tank.
