Description

Technical Field

[0001] This utility model belongs to the field of injector technology, specifically an injection device for preventing and treating periodontitis. Background Technology

[0002] Periodontitis is a localized bacterial infection caused by pathogenic microorganisms in the periodontal pockets. In the prevention and treatment of periodontitis, a periodontal injector is often used to inject therapeutic drugs into the inner side of the periodontium to prevent and treat periodontitis. This periodontal injector is similar in shape to an ordinary syringe, but the difference is that it has an L-shaped injection needle at the end, which makes it easier to inject drugs into the inner side of the periodontium.

[0003] Existing injection devices for the prevention and treatment of periodontitis typically involve fixing an L-shaped needle to the output end of a syringe, inserting the L-shaped needle into the periodontal pocket, and manually pressing the plunger. This causes the plunger to move the piston along the inside of the syringe, pushing the medication through the L-shaped needle and injecting it into the periodontal pocket, thus achieving drug injection into the inner periodontal tissue.

[0004] However, in actual use, because the L-shaped needle tube is higher than the surface of the syringe, the tip of the L-shaped needle tube may come into contact with the table when the syringe is placed on the table, causing the L-shaped needle tube to be contaminated with bacteria on the table, resulting in bacterial infection in the patient. Utility Model Content

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: an injection device for preventing and treating periodontitis, including a syringe 1, an L-shaped needle tube 2 on one side of the syringe 1, a support device 3 on one side of the syringe 1, the support device 3 including a perforated rod 31, an adjustment device 4 between the perforated rod 31 and the syringe 1, a spring rod 33 slidably connected to the inner wall of the perforated rod 31, the other end of the spring in the spring rod 33 being fixedly connected to the perforated rod 31, and a support plate 34 fixedly connected to one end of the spring rod 33, the surface of the support plate 34 being higher than the L-shaped needle tube 2. By setting the support device 3, the spring rod 33... Under the reaction force of the spring, the spring rod 33 continuously pushes the support plate 34 to move closer to the L-shaped needle tube 2, so that the support plate 34 can be positioned on the side of the syringe 1 near the L-shaped needle tube 2 to provide oblique support for the syringe 1. This causes the side of the syringe 1 near the L-shaped needle tube 2 to tilt upward, preventing the L-shaped needle tube 2 from contacting the table. This achieves the protection of the L-shaped needle tube 2 when it is placed on the table, reducing the contact between the needle tip of the L-shaped needle tube 2 and the table when the syringe 1 is placed on the table. This reduces the risk of the L-shaped needle tube 2 being contaminated with bacteria on the table, which could lead to bacterial infection in the patient. This improves the cleanliness of the L-shaped needle tube 2 when it is placed.

[0027] Specifically, such as Figure 2 and Figure 3As shown, a reinforcing block 36 is fixedly connected to the side of the spring rod 33 near the support plate 34. The reinforcing block 36 is fixedly connected to the support plate 34. By setting the reinforcing block 36, the connection strength between the spring rod 33 and the support rod can be increased, reducing the possibility of separation between the support rod and the spring rod 33. An iron sheet 32 ​​is fixedly connected to one side of the hole rod 31. A magnet 37 is fixedly connected to the end of the spring rod 33 away from the support plate 34. By setting the magnet 37, when the support plate 34 is squeezed during the use of the syringe 1, the support plate 34 pushes the spring rod 33 and the magnet 37 towards the iron sheet 32, so that the magnet 37 fixes the support plate 34 by adsorbing with the iron sheet 32, reducing the possibility of the support plate 34 affecting the person injecting the drug. A rubber pad 35 is fixedly connected to one side of the support plate 34. The surface of the rubber pad 35 has multiple protrusions. By setting the rubber pad 35, the rubber pad 35 can increase the fit between the support plate 34 and the table, and at the same time increase the friction between the support plate 34 and the table, reducing the possibility of the support plate 34 sliding.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, the adjusting device 4 includes a collar 41, which is sleeved on the syringe 1 and fixedly connected to the orifice rod 31. A rectangular tube 42 is fixedly connected to the side of the collar 41 away from the orifice rod 31. A screw 43 is threadedly connected to the inner wall of the rectangular tube 42. One end of the screw 43 is rotatably connected to a pressure plate 44 via a bearing. The pressure plate 44 is located inside the rectangular tube 42. By setting the adjusting device 4, the collar 41 is first manually moved, causing it to slide along the surface of the syringe 1 and drive the orifice rod 31 and the support plate 34 to move. When the support plate 34 moves to the designated position, the screw 43 is manually rotated, causing it to move up and down along the inside of the rectangular tube 42. This causes the screw 43 to drive the pressure plate 44 to move closer to the syringe 1, so that the pressure plate 44 moves to the position of squeezing the surface of the syringe 1 and fixing the position of the collar 41. This achieves the position adjustment of the support plate 34, allowing the position of the support plate 34 to be adjusted and supported according to different syringe tubes, further improving the flexibility of the support device 3.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, an operating block 46 is fixedly connected to the end of the screw 43 away from the pressure plate 44. By setting the operating block 46, the operating area of ​​the screw 43 can be increased, and the convenience of manually rotating the screw 43 can be improved. An anti-slip pad 45 is fixedly connected to one side of the pressure plate 44. The surface of the anti-slip pad 45 is provided with multiple protrusions. By setting the anti-slip pad 45, the friction and fit between the pressure plate 44 and the surface of the syringe 1 can be increased, while reducing the wear caused by the pressure plate 44 on the surface of the syringe 1.

[0030] The working principle of this utility model is as follows:

[0031] S1. First, fix the L-shaped needle tube 2 to the output end of the syringe 1. Then, insert the L-shaped needle tube 2 into the periodontal pocket and manually press the plunger to make the plunger drive the piston to move along the inside of the syringe 1 and push out the liquid medicine inside through the L-shaped needle tube 2, so that the liquid medicine is injected into the periodontal pocket through the L-shaped needle tube 2, thereby achieving drug injection on the inner side of the periodontium.

[0032] S2. First, manually move the collar 41 so that it slides along the surface of the syringe 1 and drives the orifice rod 31 and the support plate 34 to move. When the support plate 34 moves to the designated position, manually rotate the screw 43 so that the screw 43 moves up and down along the inside of the rectangular cylinder 42. The screw 43 drives the pressure plate 44 to move closer to the syringe 1 so that the pressure plate 44 moves to the position of squeezing the surface of the syringe 1 to fix the position of the collar 41, thereby achieving the position adjustment of the support plate 34.

[0033] S3. At this time, under the reaction force of the spring in the spring rod 33, the spring rod 33 always pushes the support plate 34 to move closer to the L-shaped needle tube 2, so that the support plate 34 can be positioned on the side of the syringe 1 close to the L-shaped needle tube 2 to provide oblique support for the syringe 1, so that the side of the syringe 1 close to the L-shaped needle tube 2 is tilted up, so that the L-shaped needle tube 2 does not contact the table, thereby achieving the placement protection of the L-shaped needle tube 2.
