[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Referring to Figures 1-4 , an embodiment provided by the present utility model: an anesthetic drug spraying device, including a spraying box 1, a pull rod 7 is slidably connected to the left side of the top of the spraying box 1, a piston 10 is fixedly connected to the bottom of the pull rod 7, a metering box 22 is fixedly connected to the top inner wall of the spraying box 1, a one-way valve 11 is fixedly connected to the bottom inner wall of the metering box 22, a spraying pipe 8 is fixedly connected to the left outer wall of the spraying box 1, the spraying pipe 8 penetrates through the left inner wall of the metering box 22, a micro motor 6 is fixedly connected to the top of the spraying box 1, a rotating shaft 13 is fixedly connected to the driving end of the micro motor 6, stirring blades 14 are evenly fixedly connected to the four sides of the outer wall of the rotating shaft 13, an observation port 5 is fixedly connected to the front end of the spraying box 1, scale lines 21 are engraved on the inner wall of the metering box 22, a box cover 3 is rotatably connected to the top of the spraying box 1, a conduit 12 is fixedly connected to the bottom of the one-way valve 11, and a handle 2 is fixedly connected to the top of the spraying box 1.

[0024] Specifically, the handle 2 fixedly connected to the top of the spraying box 1 facilitates lifting the spraying box 1 for movement. The box cover 3 rotatably connected to the top of the spraying box 1 can ensure the overall sealing performance. The support frame 4 fixedly connected to the top can fix the spraying pipe 8 when not in use, playing a role of supporting and organizing. The micro motor 6 on the top of the spraying box 1 is mainly small in size and light in weight. Starting the micro motor 6 drives the rotating shaft 13 fixedly connected to the driving end to rotate, and the rotating shaft 13 will drive the stirring blades 14 on the four sides of the outer wall to rotate, thereby stirring the anesthetic drug, replacing the situation of manually shaking the drug before use. Pulling the pull rod 7 drives the piston 10 to move upward, so that the anesthetic drug enters the metering box 22 by pressure. The one-way valve 11 on the conduit 12 can prevent the anesthetic drug from flowing back into the spraying box. At this time, the position of the anesthetic drug reaching the scale line 21 can be observed through the observation port 5 to determine the amount of dosage. The observation port 5 is a piece of transparent glass fixed in front of the spraying box 1.

[0025] A spray head 15 is slidably connected to the right side of the spray pipe 8. Four sides of the left end of the spray head 15 are fixedly connected with buckles 17. Inner walls of the left ends of the buckles 17 are fixedly connected with springs 20. Upper and lower sides of the springs 20 are fixedly connected with clamping blocks 19. The clamping blocks 19 are slidably connected to the inner walls of the buckles 17. The top of the spray box 1 is fixedly connected with a support frame 4. The top end of the support frame 4 is clamped with the spray pipe 8. The outer diameter of the right side of the spray pipe 8 is threadedly connected with a spray cover 16. Four sides of the right end of the spray pipe 8 are provided with clamping grooves 18. The shape of the clamping grooves 18 is matched with the shape of the buckles 17.

[0026] Specifically, the spray head 15 on the right side can be directly inserted into the spray pipe 8 on the left side, and then the spray head 15 is clamped by the buckle 17 structure on the left side of the spray head 15 and the clamping groove 18 on the right side of the spray pipe 8. When replacement is needed, just pull it out forcefully. The main structure of the buckle 17 is that the upper and lower clamping blocks 19 are slidably connected to the inner wall of the buckle 17 and are fixed in the middle by a spring 20. When the buckle 17 moves towards the clamping groove 18, the upper and lower clamping blocks 19 will be squeezed together. When the buckle 17 reaches the bottom of the clamping groove 18, the upper and lower clamping blocks 19 will be reset in the clamping groove 18 under the action of the spring 20 and be clamped. The triangular clamping blocks 19 are convenient for not getting stuck when clamping, and when replacing the spray head 15, just pull it out with force, which facilitates the replacement of the spray head 15 to face different scenarios and the convenient disassembly of the spray head 15 for cleaning in the later stage.

[0027] Working principle: First, open the box cover 3, pour the anesthetic drug into the spray box 1, screw on the box cover 3, then start the micro motor 6. The micro motor 6 drives the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, the stirring blades 14 on the outer walls of its four sides rotate, so that the anesthetic drug is evenly mixed, reducing the habit of manual shaking. At this time, according to how much anesthetic drug the patient needs, just pull the pull rod 7. The pull rod 7 drives the piston 10 fixedly connected to the bottom to move upward, and the anesthetic drug can enter the metering box 22 from the conduit 12. The one-way valve 11 at the bottom of the metering box 22 can prevent the anesthetic drug from flowing back into the spray box 1. At this time, just observe the scale line 21 through the observation port 5 to take out an appropriate amount of anesthetic drug dose, so as to make the anesthetic effect on the patient good and reduce the discomfort of the patient with the anesthetic effect. Then pick up the spray pipe 8, align the spray cover 16 with the patient's mouth. The spray cover 16 can prevent the patient from sneezing and the like, reducing the spread of the patient's virus. After that, align the spray head 15 with the part of the patient that needs to be anesthetized, open the control valve 9, press down the pull rod 7, and spraying can be carried out. The spray head 15 that can be conveniently disassembled can be used to face different parts of the patient with different-shaped spray heads 15, reducing the difficulty of the doctor's anesthetic process and being convenient for direct disassembly and cleaning in the later stage.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
