detailed description

As shown in Figures 1 and 2, the utility model provides a cavity mucosal anesthesia atomization device, which includes: a body 1 with a liquid outlet 1a and a liquid inlet 1b; a nozzle 7 detachably connected to the liquid outlet 1a; The liquid storage handle 3 detachably connected to the liquid inlet 1b; the water pump assembly 2 installed in the body 1 for pumping the anesthetic liquid in the liquid storage handle 3 to the nozzle 7, the water pump assembly 2 has a liquid outlet 2a and a liquid inlet Port 2b; a wrench 4 installed on the body 1 to control the work of the water pump assembly 2; wherein, the liquid outlet 2a communicates with the nozzle 7 through the liquid outlet pipe 5; the liquid inlet 2b communicates with the liquid storage handle 3 through the liquid inlet pipe 6 .

The nozzle 7 and the liquid outlet 1a of the utility model are preferably threaded or clamped, which is convenient for disassembly and replacement after use, and avoids nozzle blockage due to repeated use or cross-infection between patients.

The liquid storage handle 3 of the utility model is threadedly connected with the liquid inlet end 1b, so that the liquid storage handle 3 can be disassembled to configure the liquid medicine according to needs, and the liquid storage handle 3 can be used as a holding part to facilitate one-handed operation.

The working principle of the present utility model is described in detail below in conjunction with accompanying drawing.

As shown in FIG. 3 , the water pump assembly 2 includes: a liquid circulation cavity 21 ; and a piston rod 22 . Wherein, one end of the piston rod 22 is located in the liquid circulation chamber 21 and is equipped with a spring 25 capable of contacting the wall of the liquid circulation chamber 21 , and the other end of the piston rod 22 protrudes out of the liquid circulation chamber 21 to contact the wrench 4 .

The liquid circulation cavity 21 has a liquid outlet 2a and a liquid inlet 2b. A one-way liquid outlet valve 23 is arranged at the liquid outlet 2a, and a one-way liquid inlet valve 24 is arranged at the liquid inlet 2b.
