[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0024] The embodiment of the present utility model discloses a local irrigation and medicine application device for periodontitis.

[0025] The present utility model provides a Figures 1-3 shown local irrigation and medicine application device for periodontitis, including a syringe barrel 1. A partition board 2 is fixedly connected inside the syringe barrel 1. The partition board 2 divides the interior of the syringe barrel 1 into two medicine storage cavities. Two pistons 3 are slidably arranged inside the two medicine storage cavities. A first adjustment mechanism is arranged inside each of the two medicine storage cavities. The two pistons 3 move respectively through the corresponding first adjustment mechanism. One end of the syringe barrel 1 is fixedly connected with a mounting frame 4. A driving mechanism is arranged inside the mounting frame 4. The two first adjustment mechanisms are both matched with the driving mechanism. A second adjustment mechanism is arranged on one side of the driving mechanism. The driving mechanism moves through the second adjustment mechanism.

[0026] By using the driving mechanism, the first adjustment mechanism can drive the corresponding piston 3 to move, so that the liquid medicine inside the corresponding medicine storage cavity can be discharged. Subsequently, through the second adjustment mechanism, the driving mechanism can drive another first adjustment mechanism to work, so that the liquid medicine inside another medicine storage cavity can be discharged, thus facilitating the user to carry out the irrigation work.

[0027] In order to move the piston 3, as Figures 2-3As shown in the figure, the first adjustment mechanism includes two lead screws 5, two sleeves 6 and two first gears 7. The two lead screws 5 are respectively rotatably connected to one side of the corresponding medicine storage cavity. The two sleeves 6 are respectively threadedly sleeved on the outer surfaces of the corresponding lead screws 5. The two sleeves 6 are respectively fixedly connected to one side of the corresponding piston 3. One ends of the two lead screws 5 respectively penetrate through one side of the corresponding medicine storage cavity. The two first gears 7 are respectively fixedly sleeved on the outer surfaces of the corresponding lead screws 5. The driving mechanism includes a U-shaped plate 8, a motor 9 and a second gear 10. The U-shaped plate 8 is slidably arranged inside the mounting frame 4. The motor 9 is fixedly connected to the inner wall of the U-shaped plate 8. The second gear 10 is fixedly sleeved on the output end of the motor 9. The second gear 10 is matched with the two first gears 7.

[0028] Start the motor 9 to make the second gear 10 rotate, and then drive the meshing first gear 7 to rotate. Subsequently, the corresponding lead screw 5 can be rotated, so that the sleeve 6 can drive the corresponding piston 3 to move.

[0029] In order to facilitate the staff to adjust the types of the ejected liquid medicine, such as Figures 1-3 As shown in the figure, the adjustment mechanism includes a telescopic rod 11, a spring 12, a connecting rod 13 and a button 14. The telescopic rod 11 is fixedly connected between the mounting frame 4 and the U-shaped plate 8. The spring 12 is slidably sleeved on the outer surface of the telescopic rod 11. The connecting rod 13 is fixedly connected to the upper surface of the U-shaped plate 8. The upper end of the connecting rod 13 penetrates through the upper surface of the mounting frame 4 and is fixedly connected to the button 14. Two limit blocks 15 are fixedly connected to the inner wall of the mounting frame 4. The U-shaped plate 8 is arranged between the two limit blocks 15.

[0030] Press the button 14, and then the U-shaped plate 8 can be moved. Next, the U-shaped plate 8 can be blocked by the lower limit block 15. At this time, the second gear 10 can mesh with the other first gear 7, so that the other piston 3 can push the corresponding liquid medicine to be ejected.

[0031] Finally, in order to prevent the two kinds of liquid medicine from mixing, as shown in Figure 2, medicine outlet holes are provided on one side of each of the two medicine storage cavities, and one-way valves 16 are arranged inside the medicine outlet holes.

[0032] The one-way valve 16 can be used to prevent the two kinds of liquid medicine from mixing together.
