Description

Technical Field

[0001] This utility model relates to the field of injection equipment technology, and more specifically, to an injection device for animal treatment. Background Technology

[0002] Animal healing involves a complex process of damage and resistance to damage caused by internal or external pathogenic factors and adverse effects, manifesting as morphological changes and / or functional disorders at the local, organ, system, or systemic levels. In a healthy state, an animal maintains a dynamic balance with its environment, with its structure and function functioning normally. Disease disrupts this balance. If the damage exceeds the animal's defense capabilities, the disease worsens, potentially leading to death; conversely, the damage may be mitigated, resulting in recovery, though some adverse consequences may remain. Treatment often involves administering appropriately formulated medications via injection devices; therefore, we need an injection device for animal therapy.

[0003] Existing animal treatment injection devices rely on manual administration of medication, with the amount controlled by observing the scale on the syringe. However, sometimes the force applied is not properly controlled, resulting in excessive medication being injected into the animal, causing discomfort. Furthermore, the length of needle insertion varies depending on the size and condition of the animal, making it difficult to control the needle insertion depth and reducing the device's practicality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an injection device for animal treatment, comprising an injection tube, an injection needle mounted on the injection tube, a piston slidably and sealed inside the injection tube, a push-pull rod fixedly connected to the side end of the piston, a push-pull plate fixedly connected to the side end of the push-pull rod, a metering plate fixedly connected to the side end of the push-pull plate, a fixing plate fixedly connected to the side end of the injection tube, a first convex groove provided on the fixing plate, the metering plate slidingly engaging with the first convex groove, a second convex groove provided on the side end of the metering plate, and a sliding arrangement inside the second convex groove. There are multiple convex plates, each threaded with a first screw. Each of the multiple convex plates has a first positioning plate adapted to a first convex groove on its side end. The first convex groove has a sliding groove on its side end, and a second positioning plate is slidably disposed inside the sliding groove. A sliding rod is fixedly connected to the side end of the second positioning plate, and a pull handle is fixedly connected to the side end of the sliding rod. A tension spring is connected between the pull handle and the fixed plate to facilitate control of the piston movement and the amount of drug injected into the animal, thus avoiding excessive drug injection that could cause discomfort to the animal.

[0008] The present invention is further configured such that a first scale line is provided on the quantitative plate to facilitate observation and adjustment of the distance between two adjacent convex plates.

[0009] The present invention is further configured such that a fixed base is fixedly connected to the side end of the injection tube, an adjustment plate is slidably arranged on the fixed base, and a U-shaped plate is fixedly connected to the side end of the adjustment plate. The U-shaped plate is located outside the injection needle, which facilitates control of the length of the injection needle inserted into the animal body.

[0010] The present invention is further configured such that a second screw adapted to the adjusting plate is threaded onto the fixing base, which facilitates the fixing of the adjusting plate and the U-shaped plate.

[0011] The present invention is further configured such that the adjustment plate is provided with a second scale line, which facilitates observation of the distance between the end of the injection needle and the side end of the U-shaped plate, and facilitates control of the length of the pillow inserted into the animal's body.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an injection device for animal treatment, which has the following beneficial effects:

[0017] 1. The convex plate slides inside the second convex groove, which facilitates the adjustment of the position of the convex plate and the first positioning plate. The pull handle, slide rod and second positioning plate are moved into the first convex groove by the tension spring. When injecting drugs into animals, the cooperation of the first positioning plate and the second positioning plate facilitates the positioning of the piston and the control of the amount of drug injected into the animal, so as to avoid injecting too much drug into the animal and causing discomfort.

[0018] 2. Multiple convex plates slide within the convex groove, facilitating adjustment of the distance between adjacent convex plates. After injecting medication into one animal, pulling the handle moves the second positioning plate into the groove. Then, to inject medication into another animal, after pushing the medication a short distance, releasing the handle allows the tension spring to pull the handle, sliding rod, and second positioning plate, moving the second positioning plate into the first convex groove. When the corresponding first positioning plate contacts the second positioning plate, the appropriate amount of medication is injected into the animal. This allows for continuous injection of medication into multiple animals, ensuring the efficiency of multiple animal injections.

[0019] 3. The adjustment plate slides on the fixed base, and the adjustment plate drives the U-shaped plate to move, which makes it easy to adjust the position of the U-shaped plate, the distance between the end of the injection needle and the U-shaped plate, and the length of the injection needle inserted into the animal body, thus improving its practicality.

[0029] Please see Figures 1-5An injection device for animal treatment includes an injection tube 1, on which an injection needle 2 is mounted. A piston 3 is slidably and sealed inside the injection tube 1. An observation plate 24 is provided on the injection tube 1 for easy observation of the drug inside the injection tube 1. A third scale line 25 is provided on the observation plate 24 for easy observation of the drug dosage inside the injection tube 1. A push-pull rod 4 is fixedly connected to the side end of the piston 3. A push-pull plate 5 is fixedly connected to the side end of the push-pull rod 4. A metering plate 6 is fixedly connected to the side end of the push-pull plate 5. A first scale line 18 is provided on the metering plate 6 for easy observation and adjustment of the distance between two adjacent convex plates 10. A fixing plate 7 is fixedly connected to the side end of the injection tube 1. A first convex groove 8 is provided on the fixing plate 7. The metering plate 6 slides in conjunction with the first convex groove 8. The measuring plate 6 has a second convex groove 9 on its side end. Multiple convex plates 10 are slidably arranged inside the second convex groove 9. Each of the multiple convex plates 10 is threaded with a first screw 11. Each of the multiple convex plates 10 has a first positioning plate 12 that matches the first convex groove 8 on its side end. The first convex groove 8 has a sliding groove 13 on its side end. A second positioning plate 14 is slidably arranged inside the sliding groove 13. A sliding rod 15 is fixedly connected to the side end of the second positioning plate 14. The sliding rod 15 is slidably engaged with the fixed plate 7. A pull handle 16 is fixedly connected to the side end of the sliding rod 15. A tension spring 17 is connected between the pull handle 16 and the fixed plate 7. A limit post 26 is fixedly connected to the side end of the pull handle 16 to limit the second positioning plate 14 and prevent the second positioning plate 14 from sliding out of the sliding groove 13.

[0030] Specifically, the sliding of the convex plate 10 within the second convex groove 9 facilitates the adjustment of the positions of the convex plate 10 and the first positioning plate 12. The tension spring 17 pulls the handle 16, slide rod 15, and second positioning plate 14 into the first convex groove 8. During drug injection into the animal, the cooperation of the first positioning plate 12 and the second positioning plate 14 facilitates the positioning of the piston 3, allowing for control of the amount of drug injected into the animal and preventing excessive drug injection that could cause discomfort. The sliding of multiple convex plates 10 within the convex grooves also facilitates the adjustment of adjacent convex plates 10. The spacing between them is such that after one animal is injected with the drug, the handle 16 is pulled to move the second positioning plate 14 into the interior of the slide groove 13. Then, the drug is injected into another animal. After the drug is pushed a short distance, the handle 16 is released, and the handle 16, slide rod 15 and second positioning plate 14 are moved by the tension spring 17. The second positioning plate 14 is moved into the interior of the first convex groove 8. When the corresponding first positioning plate 12 contacts the second positioning plate 14, the corresponding amount of drug is injected into the animal's body. This facilitates the continuous injection of drugs into multiple animals and ensures the efficiency of injecting drugs into multiple animals.

[0031] Please see Figure 1 and Figure 4The side end of the injection tube 1 is fixedly connected to a fixing seat 19. An adjusting plate 20 is slidably arranged on the fixing seat 19. A U-shaped plate 21 is fixedly connected to the side end of the adjusting plate 20. In order to facilitate the replacement of the injection needle 2, the size of the U-shaped plate 21 is set according to the usage requirements. The U-shaped plate 21 is located outside the injection needle 2. A second screw 22 that matches the adjusting plate 20 is threaded on the fixing seat 19 to facilitate the fixing of the adjusting plate 20 and the U-shaped plate 21. A second scale line 23 is provided on the adjusting plate 20 to facilitate the observation of the distance between the end of the injection needle 2 and the side end of the U-shaped plate 21, so as to facilitate the control of the length of the pillow inserted into the animal body.

[0032] Specifically, by sliding the adjusting plate 20 on the fixed base 19, the adjusting plate 20 drives the U-shaped plate 21 to move, which facilitates the adjustment of the position of the U-shaped plate 21, the adjustment of the distance between the end of the injection needle 2 and the U-shaped plate 21, and the adjustment of the length of the injection needle 2 inserted into the animal body, thus improving its practicality.

[0033] In summary, when using the overall equipment:

[0034] Insert the injection needle 2 into the drug compartment. Move the handle 16, push-pull rod 4, and piston 3. During piston 3 movement, the drug is drawn into the injection tube 1. Then, the air inside the injection tube 1 is expelled, allowing the amount of drug in the injection tube 1 to be injected into multiple animals. The convex plate 10 slides within the convex groove. Adjust the distance between the lower first positioning plate 12 and the second positioning plate 14 according to the amount of drug injected into the animal and the first scale line 18. Then, adjust the upper convex plates 10 and the first positioning plate 12 according to the first scale line 18. Adjust the distance between adjacent first positioning plates 12 to a suitable level according to the amount of drug injected into the animal. Tighten the first screw 11 so that its side end abuts against the side end of the second convex groove 9, fixing the corresponding convex plate 10. Adjust the position of the U-shaped plate 21 using the adjusting plate 20. The injection needle is judged by observing the scale value at the bottom surface of the fixing seat 19. The distance between the end of the head 2 and the U-shaped plate 21 is determined, and then the injection needle 2 is inserted into the animal's body. When the side end of the U-shaped plate 21 contacts the animal's skin, the insertion of the injection needle 2 into the animal's body is stopped. Then, the push-pull plate 5, the push-pull rod 4, and the piston 3 are pushed to move. When the first positioning plate 12 contacts the second positioning plate 14, a certain amount of drug inside the injection tube 1 is injected into the animal's body. Then, the injection needle 2 is replaced, and the injection needle 2 is inserted into another animal's body. Then, the pull handle 16 is pulled to move the second positioning plate 14 into the interior of the slide groove 13. Then, the drug is injected into another animal. After pushing the drug a short distance, the pull handle 16 is released. The pull handle 16, the slide rod 15, and the second positioning plate 14 are moved by the tension spring 17 to move the second positioning plate 14 into the interior of the first convex groove 8. When the corresponding first positioning plate 12 contacts the second positioning plate 14, the corresponding amount of drug is injected into the animal's body. This facilitates the continuous injection of drugs into multiple animals.
