Technical Field
[0001] This invention relates to the field of animal treatment technology, and in particular to a puncture device for treating livestock and veterinary animals. Background Technology
[0002] Animal therapy is an important part of veterinary medicine. It refers to the application of professional knowledge and skills by veterinarians to diagnose, treat, and care for sick animals. The aim is to restore animal health, improve production performance, alleviate pain, and control the spread of diseases. Targeted treatment eliminates the root cause of diseases, relieves symptoms, and restores the animal's physiological balance. After treatment, animals can eat, grow, or reproduce better, improving the economic benefits of animal husbandry, preventing the spread of diseases in herds or the environment, and protecting the health of other animals and humans. When animals are sick, antibiotics can be injected into the pleural cavity to treat pleurisy, and anti-inflammatory drugs can be injected into the joint cavity to treat arthritis, increasing the local drug concentration and reducing systemic side effects. In cases of abdominal infection, physiological saline can be injected through puncture to flush out pus and necrotic tissue and promote healing.
[0003] During traditional puncture procedures, animals may tremble due to pain. When the animal trembles, the needle of the traditional puncture device may not remain stable and may deviate from the target position, affecting the drug injection effect. Needle displacement may result in the drug not being accurately injected into the target tissue or organ, or even injected into the wrong site, causing treatment failure or animal discomfort. When administering drugs with traditional puncture devices, the operator needs to visually observe whether the drug injection is finished, which is prone to errors. The operator may stop the drug injection too early, resulting in insufficient drug dosage. Therefore, a new puncture device for animal treatment in animal husbandry and veterinary medicine is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability of the needle in traditional puncture devices to remain stable when animals tremble due to pain, thus deviating from the target position and affecting the drug injection effect. Needle displacement may lead to inaccurate drug injection into the target tissue or organ, or even injection into the wrong site, resulting in treatment failure or animal discomfort. In addition, traditional puncture devices require operators to visually observe whether the drug injection is completed, which is prone to errors. Therefore, this invention proposes a puncture device for animal treatment in animal husbandry and veterinary medicine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A puncture device for treating livestock and veterinary animals includes a cylindrical body, a piston movably connected to the inner side of the cylindrical body, a first spring shared between the piston and the cylindrical body, a movable cylinder movably connected to the end of the cylindrical body, a needle mounted on the side of the movable cylinder away from the cylindrical body, a connecting tube shared between the cylindrical body and the movable cylinder, and a puncture assembly on the cylindrical body. The puncture assembly includes a second movable plate mounted on the outer side of the movable cylinder, a first movable rod slidably disposed on the inner side of the cylindrical body, a locking unit on the cylindrical body connecting the second movable plate and the first movable rod, a prompting plate slidably disposed on the inner side of the cylindrical body, an impact head mounted on the side of the prompting plate, and a hollow tube mounted on the inner side of the cylindrical body. A transparent window is mounted on the outer side of the cylindrical body. When the needle is inserted into the patient's body, the locking unit releases the second movable plate. The locking of the movable plate and the first movable rod makes the movable cylinder and the cylinder body movably connected, enabling the movable cylinder and needle to move with the animal's shaking. This effectively avoids needle displacement caused by animal shaking, ensuring smooth drug injection and improving the success rate of drug injection when the animal is uncooperative. It adapts to various states that animals may encounter in actual use. The first spring automatically resets and drives the piston to move for drug injection. When the first movable rod moves, it presses the indicator plate to the transparent window, and at the same time, the impact head presses the hollow tube to emit an indicator sound. Through the combination of visual and auditory prompts, operators can quickly and intuitively observe whether the drug injection is completed, avoiding operational errors or delays that may occur due to the inability to judge the drug injection progress in time, thus improving work efficiency and accuracy.
[0006] The above technical solution further includes: A universal ball is movably connected to one end of the cylinder near the movable cylinder. A first telescopic rod is installed on the outside of the universal ball. The end of the first telescopic rod away from the universal ball is fixedly connected to the movable cylinder. The movable cylinder and the needle can move in accordance with the shaking of the animal by the multi-directional movement of the universal ball and the telescopic nature of the first telescopic rod.
[0007] A round rod is mounted on the side of the piston, and the end of the round rod away from the piston is fixedly connected to the circular plate of the movable plate. The first movable rod is mounted on the side of the first movable rod close to the round rod.
[0008] The locking unit includes a fixed rod movably connected to the inner side of the second movable plate, a third movable rod installed at the upper end of the fixed rod, and a second spring installed between the third movable rod and the second movable plate. The second spring is sleeved on the outer side of the fixed rod, and after the second spring resets, it drives the fixed rod and the third movable rod to move upward.
[0009] The locking unit also includes a second fixing groove on the inner side of the cylinder and a first fixing groove on the upper part of the first movable rod. The first fixing groove and the second fixing groove are movably connected to the fixing rod. The size of the opening of the first fixing groove and the second fixing groove are adapted to the size of the fixing rod. After the fixing rod moves up, it moves to the outside of the first fixing groove and the second fixing groove.
[0010] A sliding groove is provided on the inner side of the cylinder, and the first movable rod is slidably disposed on the inner side of the sliding groove.
[0011] An annular groove is provided on the inner side of the cylinder, and the annular groove is connected to the sliding groove. A second telescopic rod is symmetrically installed on the inner side of the annular groove, and the ends of the two second telescopic rods are fixedly connected to the indicator plate.
[0012] A first magnet is symmetrically installed on the side of the indicator board near the hollow tube, and a second magnet is symmetrically installed on the side of the hollow tube near the indicator board. The first magnet and the second magnet attract each other.
[0013] The indicator panel is positioned on the movement trajectory of the first movable rod, and the hollow tube is positioned on the movement trajectory of the impact head. After the first movable rod moves, it presses against the indicator panel.
[0014] The positions of the two first magnets and the second magnet correspond to each other.
[0015] The present invention has the following beneficial effects: 1. In this invention, during puncture, the connection between the first movable rod and the cylinder can be quickly released, and the drug injection is automatically triggered. Then, the movable cylinder and the cylinder become movable. When the animal shakes, the movable cylinder and the needle can move with the animal's shaking, effectively avoiding needle displacement caused by the animal shaking, ensuring the smooth progress of the drug injection, improving the success rate of drug injection when the animal is uncooperative, and adapting to various states that animals may encounter in actual use.
[0016] 2. In this invention, during the injection process, the indicator plate is pressed by the first movable rod. When the indicator plate moves, its outer red side is exposed. The hollow tube is struck by the impact head to emit an indicator sound. Through the combination of visual and auditory prompts, the operator can quickly and intuitively observe whether the injection process is complete, avoiding possible operational errors or delays due to the inability to judge the injection progress in a timely manner, thus improving work efficiency and accuracy.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1 like Figure 1 - Figure 6As shown, the present invention proposes a puncture device for animal treatment in livestock and veterinary medicine, comprising a cylindrical body 1, a piston 2 movably connected to the inner side of the cylindrical body 1, a first spring 4 installed between the piston 2 and the cylindrical body 1, a movable cylinder 7 movably connected to the end of the cylindrical body 1, a needle 8 installed on the side of the movable cylinder 7 away from the cylindrical body 1, a connecting tube 9 installed between the cylindrical body 1 and the movable cylinder 7, and a puncture assembly provided on the cylindrical body 1. The puncture assembly includes a second movable plate 15 installed on the outer side of the movable cylinder 7, a first movable rod 11 slidably disposed on the inner side of the cylindrical body 1, a locking unit on the cylindrical body 1 connecting the second movable plate 15 and the first movable rod 11, a prompting plate 22 slidably disposed on the inner side of the cylindrical body 1, an impact head 24 installed on the side of the prompting plate 22, a hollow tube 25 installed on the inner side of the cylindrical body 1, and a transparent window 20 installed on the outer side of the cylindrical body 1. The needle 8 is inserted into the patient's body, and the locking unit... The locking mechanism of the second movable plate 15 and the first movable rod 11 is released, and the movable cylinder 7 and the cylinder body 1 become movably connected. This allows the movable cylinder and the needle to move with the animal's shaking, effectively preventing the needle from shifting due to the animal's shaking, ensuring the smooth progress of the injection, improving the success rate of injection even when the animal is uncooperative, and adapting to various states that animals may encounter in actual use. The first spring 4 automatically resets and drives the piston 2 to move for injection. When the first movable rod 11 moves, it presses the indicator plate 22 to the transparent window 20, and at the same time, the impact head 24 presses the hollow tube 25 to emit an indicator sound. Through the combination of visual and auditory prompts, the operator can quickly and intuitively observe whether the injection is finished, avoiding operational errors or delays that may occur due to the inability to judge the injection progress in time, thus improving work efficiency and accuracy.
[0021] A universal ball 5 is movably connected to one end of the cylinder 1 near the movable cylinder 7. A first telescopic rod 6 is installed on the outside of the universal ball 5. The end of the first telescopic rod 6 away from the universal ball 5 is fixedly connected to the movable cylinder 7. The movable cylinder 7 and the needle 8 can move with the shaking of the animal due to the multi-directional movement of the universal ball 5 and the telescopic nature of the first telescopic rod 6.
[0022] A round rod 3 is mounted on the side of the piston 2. The end of the round rod 3 away from the piston 2 is fixedly connected to the circular plate 10 of the movable plate. The first movable rod 11 is mounted on the side of the first movable rod 11 close to the round rod 3.
[0023] The locking unit includes a fixed rod 16 movably connected to the inner side of the second movable plate 15, a third movable rod 18 installed at the upper end of the fixed rod 16, and a second spring 17 installed between the third movable rod 18 and the second movable plate 15. The second spring 17 is sleeved on the outer side of the fixed rod 16. After the second spring 17 is reset, it drives the fixed rod 16 and the third movable rod 18 to move upward.
[0024] The locking unit also includes a second fixing groove 14 on the inner side of the cylinder 1 and a first fixing groove 13 on the upper part of the first movable rod 11. The first fixing groove 13 and the second fixing groove 14 are movably connected to the fixing rod 16. The size of the opening of the first fixing groove 13 and the second fixing groove 14 is adapted to the size of the fixing rod 16. After the fixing rod 16 moves up, it moves to the outside of the first fixing groove 13 and the second fixing groove 14.
[0025] A sliding groove 12 is provided on the inner side of the cylinder 1, and the first movable rod 11 is slidably disposed on the inner side of the sliding groove 12.
[0026] In this embodiment, when puncture is required, the cylinder 1 can be held while the thumb presses the third movable rod 18. The third movable rod 18 drives the fixed rod 16 to move downwards. At this time, the second spring 17 retracts. When the third movable rod 18 moves downwards, it simultaneously inserts into the first fixed groove 13 and the second fixed groove 14, maintaining the lock between the second movable plate 15 and the first movable rod 11 and the cylinder 1. Then, the movable cylinder 7 is inserted into the animal body. At this time, the third movable rod 18 can be quickly released, and the second spring 17, which is in the retracted state, will return to its original position. After the second spring 17 returns to its original position, it drives the fixed rod 16 and the third movable rod 18 to move upwards. After the fixed rod 16 moves upwards, it moves into the first fixed groove 13 and the second fixed groove 14. Outside the fixed groove 14, the movable cylinder 7 is no longer fixed to the cylinder body 1 by the second movable plate 15. At the same time, the movable cylinder 7 and the cylinder body 1 are movably connected. At this time, the first movable rod 11 is no longer locked to the piston 2 by the movable plate circular plate 10 and the circular rod 3. At the same time, the first spring 4 is reset. The force generated after the first spring 4 is reset drives the piston 2 to move. When the piston 2 moves, it drives the liquid medicine to move and is injected into the animal body through the connecting tube 9 and the needle 8. When the animal shakes, the movable cylinder 7 and the needle 8 can move with the animal's shaking by the multi-directional movement of the universal ball 5 and the telescopic nature of the first telescopic rod 6, so as to avoid the needle 8 from shifting due to the shaking of the animal and affecting the injection work.
[0027] Example 2 like Figure 1 - Figure 6 As shown, based on Embodiment 1, an annular groove 19 is provided on the inner side of the cylinder 1. The annular groove 19 is connected to the sliding groove 12. Second telescopic rods 21 are symmetrically installed on the inner side of the annular groove 19. The ends of the two second telescopic rods 21 are fixedly connected to the indicator plate 22.
[0028] A first magnet 23 is symmetrically installed on the side of the indicator plate 22 near the hollow tube 25, and a second magnet 26 is symmetrically installed on the side of the hollow tube 25 near the indicator plate 22. The first magnet 23 and the second magnet 26 attract each other.
[0029] The indicator plate 22 is positioned on the movement trajectory of the first movable rod 11, and the hollow tube 25 is positioned on the movement trajectory of the impact head 24. After the first movable rod 11 moves, it presses against the indicator plate 22.
[0030] The positions of the two first magnets 23 and the second magnet 26 correspond to each other.
[0031] In this embodiment, after the fixed rod 16 moves upward and reaches the outside of the first fixed groove 13, the first spring 4 resets and drives the piston 2 to move. When the piston 2 moves, it drives the first movable rod 11 to move along the sliding groove 12 through the round rod 3 and the movable plate 10. After the first movable rod 11 moves, it presses the indicator plate 22. After being pressed, the indicator plate 22 moves along the annular groove 19 until the indicator plate 22 moves to the annular groove 19. Since the outside of the indicator plate 22 is red, when the indicator plate 22 moves to the position of the annular groove 19, the drug injection work is completed. At the same time, the indicator plate 22 moves to the point where the first magnet 23 and the second magnet 26 attract each other, increasing the speed of the indicator plate 22. Then, the impact head 24 and its hollow tube 25 emit a warning sound. By observing the red color of the indicator plate 22 at the annular groove 19 and the warning sound emitted by the hollow tube 25, the end of the drug injection work can be quickly observed.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
