[0037] The connecting member includes two fixing plates 7, which correspond to each other and are fixedly connected to the outer surface of the medicine outlet tube 4, and a connecting plate 8 is rotatably connected between the two fixing plates 7. A supporting plate 9 is fixedly connected to one side of the connecting plate 8, and the side edges of the supporting plate 9 are all rounded.

[0038] Two sliding assemblies are symmetrically arranged on the medicine outlet pipe 4 , and the sliding assemblies drive the two slide plates 13 to slide on the upper and lower sides of the medicine outlet pipe 4 respectively.

[0039] One end of the slide plate 13 is fixedly connected to a push plate 14, and two push rods 17 are fixedly connected between the push plate 14 and the nozzle 6. A connecting rod 15 is hinged between one side of the slide plate 13 and the support plate 9.

[0040] The sliding assembly includes two sliding rods 20. The end of the slide plate 13 away from the push plate 14 is fixedly connected to the moving plate 16, and the two sliding rods 20 are fixedly connected to the side of the moving plate 16 away from the slide plate 13. The ends of the four sliding rods 20 located on the medicine outlet tube 4 are fixedly connected by a U-shaped operating rod 22.

[0041] The medicine outlet tube 4 is provided with a limit assembly of a slide bar 20. Two limit assemblies are provided, and the slide assembly cooperates with the limit assembly.

[0042] The limiting assembly includes a first limiting plate 18 and a second limiting plate 19, which are respectively fixedly connected to the two ends of the outer surface of the medicine outlet tube 4, and the first limiting plate 18 is located between the second limiting plate 19 and the movable plate 16. Two sliding rods 20 on one side of the movable plate 16 slide through the corresponding first limiting plate 18 and second limiting plate 19 in sequence.

[0043] Two springs 21 are fixedly connected between the first limiting plate 18 and the movable plate 16 , and two sliding rods 20 on one side of the movable plate 16 pass through the corresponding springs 21 , respectively.

[0044] The medicine outlet pipe 4 is provided with a positioning assembly of a slide plate 13. Two positioning assemblies are provided, and the sliding assembly cooperates with the positioning assembly.

[0045] The positioning assembly includes a positioning plate 10, which is fixedly connected to the outer surface of the medicine outlet tube 4.

The two sliders 12 are slidably connected to the corresponding positioning grooves 11 respectively.

[0046] Working principle:

[0047] When in use, pour the anesthetic into the spray bottle 1. Move the spray bottle 1 to the patient's mouth, then the patient opens his mouth, and move the spray head 6 to the patient's oral cavity, and the fixing plate 7 is located at the lips in the oral cavity.

[0048] The operating rod 22 is pushed toward the side away from the spray bottle 1, so that the slide bar 20 passes through the second limiting plate 19 and the first limiting plate 18, and pushes the moving plate 16. The slide plate 13 and the push plate 14 slide on one side of the positioning plate 10, and the slider 12 slides inside the positioning groove 11, and the spring 21 is stretched.

[0049] The push plate 14 pushes the nozzle 6 toward the pharynx of the patient through the push rod 17 , and the movement of the nozzle 6 toward the pharynx will lengthen the telescopic tube 5 .

[0050] The slide plate 13 drives one end of the connecting rod 15 to slide toward the direction close to the spray head 6, so that the connecting rod 15 rotates, and the connecting plate 8 rotates between the two fixed plates 7. The other end of the connecting rod 15 pushes the supporting plate 9, and then the connecting rod 15 pushes the two supporting plates 9 to rotate toward the two sides of the medicine outlet pipe 4. The two supporting plates 9 rotate toward the upper and lower sides of the medicine outlet pipe 4, that is, the angles between the medicine outlet pipe 4 and the two supporting plates 9 gradually increase.

[0051] Until the ends of the two support plates 9 away from the fixing plate 7 are respectively in contact with the upper and lower jaws of the patient, the patient's mouth is opened, and the nozzle 6 moves to the pharynx of the patient. The angle of the support plates 9 can be adjusted according to the patient's condition.

[0052] After adjustment, the handle 3 is pressed to allow the anesthetic drug in the spray bottle 1 to enter the drug outlet tube 4 through the delivery tube 2, and then pass through the telescopic tube 5 and spray to the patient's pharynx through the spray head 6. During the spraying process, the doctor can check the spraying status of the pharynx through both sides of the drug outlet tube 4.

[0053] After spraying is completed, the hand releases the operating lever 22, and under the action of the elastic force of the spring 21, the movable plate 16 is pulled toward the side close to the first limit plate 18, so that the slide bar 20 passes through the first limit plate 18 and the second limit plate 19. At the same time, the slide plate 13 and the push plate 14 are driven to slide on one side of the positioning plate 10, and the slide block 12 slides in the positioning groove 11.

[0054] The push plate 14 will pull the spray head 6 toward the side close to the medicine outlet pipe 4 through the push rod 17, and the telescopic tube 5 will gradually shorten and recover.

[0055] The slide plate 13 drives one end of the connecting rod 15 to slide toward the first limit plate 18, so that the connecting rod 15 rotates, and the other end of the connecting rod 15 pulls the supporting plate 9 to rotate toward the outer surface of the medicine outlet tube 4, and the connecting plate 8 rotates between the two fixing plates 7. The ends of the two supporting plates 9 are respectively separated from the upper and lower jaws of the patient until they are restored to the initial state. The telescopic tube 5 also returns to the initial state.

[0056] The support plate 9 and the spray head 6 are removed from the patient's oral cavity, and the spray device is disinfected for reuse.

[0057] Example 2

[0058] like Figure 8 As shown, the difference between this embodiment and embodiment 1 is that a delivery pipe 2 is fixedly arranged inside the spray bottle 1, an inverted conical bottom plate 23 is fixedly connected to the bottom of the inner cavity of the spray bottle 1, and the bottom end of the delivery pipe 2 is fixedly connected to the medicine outlet at the bottom of the bottom plate 23 through a medicine receiving pipe 24. The delivery pipe 2 is a hose.

[0059] Working principle:

[0060] When adding medicine to the interior of the spray bottle 1, the anesthetic will flow to the top of the bottom plate 23.

[0061] When spraying the medicine, the handle 3 is pressed to allow the medicine on the top of the bottom plate 23 to enter the inside of the delivery tube 2 through the medicine receiving tube 24, and then enter the inside of the medicine outlet tube 4 and be sprayed out. The bottom plate 23 is an inverted cone, which can make most of the medicine on the bottom plate 23 flow into the medicine receiving tube 24, reducing the situation where there is a lot of medicine left at the bottom of the spray bottle 1, and reducing the waste of anesthetic drugs.
