Description

Technical Field

[0001] This invention relates to the field of disease prevention and control injection technology, specifically a continuous syringe for veterinary disease prevention and control. Background Technology

[0002] Veterinary disease prevention and control injection is a measure to prevent and control infectious diseases by vaccinating animals with biological products such as vaccines, bacterial vaccines or immune serums to stimulate the specific resistance of the animal body. It is a technical method of injecting vaccines into the animal body through a needle to achieve the purpose of treating or preventing diseases or scientific research. In veterinary disease prevention and control injection operations, the dosage control effect of traditional syringes is not good. Existing devices rely on static scale markings on the surface of the syringe. Operators need to observe the scale on the surface of the syringe multiple times and manually control the movement distance of the lever to determine the dosage when drawing the liquid. This is relatively troublesome to operate. When performing injection operations on a large number of animals continuously, fatigue can easily lead to errors in the amount of liquid drawn. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous syringe for the prevention and treatment of veterinary diseases, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a continuous syringe for veterinary disease prevention and control, comprising a syringe, a one-way valve tube connected to the end of the syringe, an injection needle inserted into the surface of the one-way valve tube, a rubber disc slidably connected to the inner wall of the syringe, a pull rod fixedly connected to the surface of the rubber disc, the end of the pull rod away from the rubber disc passing through the syringe and extending to the outer end of the syringe, a one-way valve seat connected to the top of the syringe, a storage cylinder threadedly connected to the inner wall of the top of the one-way valve seat, the storage cylinder being threadedly connected to the one-way valve seat for easy disassembly of the storage cylinder for liquid filling, a spring fixedly connected to the end of the syringe away from the one-way valve tube, and a scale limit component provided on the surface of the syringe; The scale limiting component includes a scale plate, the surface of which is fixedly connected to the surface of the syringe. A movable frame is slidably connected to the surface of the scale plate. A spring is fixedly connected to the bottom of the movable frame. A semi-circular frame is fixedly connected to the end of the spring away from the movable frame. A retaining plate is fixedly connected to the inner wall of the semi-circular frame. A retaining plate is fixedly connected to the bottom of the syringe. A fixing plate is fixedly connected to the bottom of the semi-circular frame. A baffle is fixedly connected to the end of the fixing plate away from the semi-circular frame. A pressing component is provided at the top of the syringe. A pressure component is provided on the surface of the storage cylinder.

[0005] Furthermore, the surface of the rubber disc contacts the inner wall of the syringe, and the end of the spring away from the syringe is fixedly connected to the surface of the pull rod.

[0006] Furthermore, there are two scale plates, which are symmetrically arranged with the syringe as the center. The spring is located below the syringe. The inner wall of the semi-circular frame is in contact with the surface of the slot plate, and the surface of the slot plate is in contact with the inner wall of the slot plate.

[0007] Furthermore, the end of the fixing plate away from the semicircular frame extends to the outer end of the syringe, the surface of the baffle contacts the end of the pull rod, and there are two spring pieces, which are symmetrically arranged with the semicircular frame as the center. The inner wall of the slot plate corresponds to the scale of the scale plate.

[0008] Furthermore, the pressing component includes a circular hole rod, the bottom of which is fixedly connected to the top of the syringe. A return spring is fixedly connected to the bottom of the inner wall of the circular hole rod, and a contact plate is fixedly connected to the top of the return spring. A pressing ring is fixedly connected to the surface of the contact plate, and an inclined plate is hinged to the surface of the contact plate. The end of the inclined plate away from the contact plate is hinged to the top of the pull rod. A sliding hole is formed on the surface of the circular hole rod.

[0009] Furthermore, the surface of the contact disc contacts the inner wall of the circular hole rod, the contact disc extends to the outer end of the circular hole rod through the sliding hole, and the surface of the contact disc is slidably connected to the inner wall of the sliding hole.

[0010] Furthermore, the pressing ring is located at the outer end of the circular hole rod, the end of the inclined plate away from the contact plate is inclined downward, and the hinge point between the inclined plate and the pull rod is located above the syringe.

[0011] Furthermore, the pressure component includes a positioning plate, the surface of which is fixedly connected to the surface of the storage cylinder. A lifting frame is slidably connected to the surface of the positioning plate. A spring rod is fixedly connected to the bottom of the lifting frame. A force-bearing frame is fixedly connected to the bottom of the spring rod. A bent rod is fixedly connected to the top of the lifting frame. A sliding rod is fixedly connected to the end of the bent rod away from the lifting frame. A circular perforated plate is fixedly connected to the surface of the sliding rod. A spring spring is fixedly connected to the top of the inner wall of the storage cylinder. The bottom of the spring spring is fixedly connected to the top of the circular perforated plate.

[0012] Furthermore, the bottom of the slide rod penetrates through the storage cylinder and extends into the interior of the storage cylinder, and two circular perforated discs are provided, which are located inside the storage cylinder and arranged one above the other.

[0013] Furthermore, the surface of the circular disc contacts the inner wall of the storage cylinder, the top of the force-bearing frame is located on the upper surface of the elastic rod, the top of the force-bearing frame contacts the bottom of the pressing ring, and the lifting frame is located on the upper surface of the positioning plate.

[0014] The present invention has the following beneficial effects: The syringe of this invention has a one-way valve tube at the end with an injection needle inserted into it, facilitating needle replacement. When the lever is pulled to move outwards from the syringe, it moves a rubber disc. The negative pressure generated by the moving rubber disc is transmitted to the inside of the one-way valve seat, causing it to open. After the one-way valve seat opens, the medication in the storage cylinder enters the syringe. The injection needle is then inserted into the animal. Releasing the lever causes the lever to move the rubber disc towards the injection needle via a spring. At this point, the one-way valve tube is open under the pressure of the rubber disc, allowing the medication to be injected into the animal through the connection between the one-way valve tube and the injection needle. This makes injection convenient. When the one-way valve tube is open, the one-way valve seat is closed, facilitating continuous liquid addition from the storage cylinder into the syringe. This allows for continuous injection into animals, improving the efficiency of animal vaccination.

[0015] After the operator measures the required dosage of medication for the animal, they pull the semi-circular frame downwards. The semi-circular frame pushes the card plate away from the inner wall of the card slot plate. At this point, the operator can move the movable frame across the surface of the scale plate. When the movable frame reaches the corresponding scale, releasing the semi-circular frame will push the card plate into contact with the inner wall of the card slot plate, using the card plate to fix the movable frame. At the same time, the fixing plate pushes the baffle to move. When the pull rod is pushed to move, the pull rod will contact the baffle, thus limiting the movement distance of the rubber disc. This allows the rubber disc to draw the corresponding medication for injection into the animal, improving the convenience of the syringe during continuous operation. When the operator injects the animal with a vaccine, they only need to adjust the baffle to the corresponding position, and the pull rod will pull the rubber disc to draw the corresponding medication. The operator does not need to frequently calibrate the medication during injection.

[0016] When the present invention requires the extraction of the drug solution, the operator pushes the pressing ring downwards. As the pressing ring moves downwards, it causes the return spring to contract via the contact plate. Simultaneously, the contact plate pushes the top of the inclined plate downwards. The angle of the inclined plate changes during this movement, pushing the pull rod towards the outer end of the syringe. This improves the ease of drug extraction by pulling the rubber disc with the pull rod. Slightly releasing the pressing ring causes it to move upwards using the elasticity of the return spring. Simultaneously, the pull rod pushes the rubber disc to compress the drug solution, causing the rubber disc to expel air from the syringe and preventing residual air from harming the animal. After inserting the injection needle into the animal, the pressing ring is completely released. At this point, the pull rod, through the return spring and its elasticity, pushes the rubber disc to compress the drug solution, allowing the drug to be automatically injected into the animal. This improves the convenience of vaccination, reduces the force required for the operator to pull the pull rod to extract the drug solution, and makes the pull rod more effortless and convenient to use.

[0017] When the pressing ring moves downward, it pushes the elastic rod downward through the force-bearing frame. As the elastic rod moves downward, it pushes the sliding rod downward through the connection between the lifting frame and the bent rod. The sliding rod then pushes the perforated disc downward inside the storage cylinder. During this movement, the perforated disc compresses and mixes the liquid, preventing sedimentation. Simultaneously, the downward movement of the perforated disc provides pressure to the liquid, ensuring it flows stably through the one-way valve seat into the syringe. The positioning plate limits the lifting frame, improving its stability during movement. The elastic rod's elastic extension allows the force-bearing frame to extend downward. When the pressing ring moves upward, the elastic spring pulls the perforated disc upward, causing it to reciprocate up-and-down with the pressing ring, thus improving the stability of the liquid supply from the storage cylinder to the syringe.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-10 As shown, the present invention is a continuous syringe for veterinary disease prevention and control, comprising a syringe 1, a one-way valve tube 8 connected to the end of the syringe 1, an injection needle 2 inserted into the surface of the one-way valve tube 8, a rubber disc 5 slidably connected to the inner wall of the syringe 1, a pull rod 6 fixedly connected to the surface of the rubber disc 5, the end of the pull rod 6 away from the rubber disc 5 passing through the syringe 1 and extending to the outer end of the syringe 1, a one-way valve seat 3 connected to the top of the syringe 1, a storage cylinder 4 threadedly connected to the inner wall of the top of the one-way valve seat 3, a spring 7 fixedly connected to the end of the syringe 1 away from the one-way valve tube 8, and a scale limiting component 9 provided on the surface of the syringe 1. The scale limiting component 9 includes a scale plate 20, the surface of which is fixedly connected to the surface of the syringe 1. A movable frame 21 is slidably connected to the surface of the scale plate 20. A spring piece 22 is fixedly connected to the bottom of the movable frame 21. A semi-circular frame 23 is fixedly connected to the end of the spring piece 22 away from the movable frame 21. A retaining plate 27 is fixedly connected to the inner wall of the semi-circular frame 23. A retaining groove plate 25 is fixedly connected to the bottom of the syringe 1. A fixing plate 24 is fixedly connected to the bottom of the semi-circular frame 23. A baffle 26 is fixedly connected to the end of the fixing plate 24 away from the semi-circular frame 23. After the operator measures the required dosage for the animal, he pulls the semi-circular frame 23 downwards, and the semi-circular frame 23 pushes the retaining plate. 27 separates from the inner wall of the slot plate 25. At this time, the operator can push the moving frame 21 to move on the surface of the scale plate 20. After the moving frame 21 moves to the corresponding scale, the semicircular frame 23 is released and the semicircular frame 23 will push the slot plate 27 to contact the inner wall of the slot plate 25. The slot plate 27 is used to fix the moving frame 21. At the same time, the baffle 26 is pushed to move through the fixing plate 24. When the pull rod 6 is pushed to move, the pull rod 6 will contact the baffle 26 to limit the movement distance of the rubber disc 5 so that the rubber disc 5 can draw the corresponding medicine for injection into the animal. The top of the syringe 1 is provided with a pressing component 10, and the surface of the storage cylinder 4 is provided with a pressure component 11.

[0024] The surface of the rubber disc 5 is in contact with the inner wall of the syringe 1, and the end of the spring 7 away from the syringe 1 is fixedly connected to the surface of the pull rod 6.

[0025] There are two scale plates 20, which are symmetrically arranged with the syringe 1 as the center. The spring 22 is located below the syringe 1. The inner wall of the semi-circular frame 23 is in contact with the surface of the slot plate 25, and the surface of the card plate 27 is in contact with the inner wall of the slot plate 25.

[0026] The fixed plate 24 extends from the end away from the semicircular frame 23 to the outer end of the syringe 1. The surface of the baffle 26 contacts the end of the pull rod 6. There are two spring pieces 22, which are symmetrically arranged with the semicircular frame 23 as the center. The inner wall of the slot plate 25 corresponds to the scale of the scale plate 20.

[0027] The pressing component 10 includes a circular rod 30, the bottom of which is fixedly connected to the top of the syringe 1. A return spring 34 is fixedly connected to the bottom of the inner wall of the circular rod 30, and a contact plate 33 is fixedly connected to the top of the return spring 34. A pressing ring 32 is fixedly connected to the surface of the contact plate 33, and a ramp 31 is hinged to the surface of the contact plate 33. The end of the ramp 31 away from the contact plate 33 is hinged to the top of the pull rod 6. A sliding hole 35 is provided on the surface of the circular rod 30. When the ramp 31 moves, its angle changes, pushing the pull rod 6 towards the outer end of the syringe 1, thus increasing the pressure. The lever 6 facilitates the extraction of medication by pulling the rubber disc 5. When the pressing ring 32 is slightly released, it moves upward using the elasticity of the return spring 34. At the same time, the lever 6 pushes the rubber disc 5 to squeeze the medication, causing the rubber disc 5 to expel air from the syringe 1. This prevents residual air in the syringe 1 from harming the animal. After the injection needle 2 is inserted into the animal's body, the pressing ring 32 is completely released. At this time, the lever 6, through the elasticity of the return spring 34 and spring 7, pushes the rubber disc 5 to squeeze the medication, allowing the medication to be automatically injected into the animal's body.

[0028] The surface of the contact plate 33 contacts the inner wall of the circular hole rod 30. The contact plate 33 extends to the outer end of the circular hole rod 30 through the sliding hole 35, and the surface of the contact plate 33 is slidably connected to the inner wall of the sliding hole 35.

[0029] The pressing ring 32 is located at the outer end of the circular rod 30, and the end of the inclined plate 31 away from the contact plate 33 is inclined downward. The hinge of the inclined plate 31 and the pull rod 6 is located above the syringe 1.

[0030] The pressure component 11 includes a positioning plate 46, the surface of which is fixedly connected to the surface of the storage cylinder 4. A lifting frame 43 is slidably connected to the surface of the positioning plate 46. A spring rod 44 is fixedly connected to the bottom of the lifting frame 43. A force-bearing frame 45 is fixedly connected to the bottom of the spring rod 44. A bent rod 42 is fixedly connected to the top of the lifting frame 43. A sliding rod 41 is fixedly connected to the end of the bent rod 42 away from the lifting frame 43. A circular perforated plate 40 is fixedly connected to the surface of the sliding rod 41. A spring is fixedly connected to the top of the inner wall of the storage cylinder 4. Spring 47, the bottom of spring 47 is fixedly connected to the top of the circular plate 40. When spring rod 44 moves downward, it pushes slide rod 41 downward through the connection between lifting frame 43 and bent rod 42. When slide rod 41 moves downward, it pushes circular plate 40 downward inside storage cylinder 4. When circular plate 40 moves, it can squeeze and mix the medicine to avoid precipitation. At the same time, when circular plate 40 moves downward, it will provide pressure to the medicine, so that the medicine can stably enter the syringe 1 through one-way valve seat 3.

[0031] The bottom of the slide bar 41 passes through the storage cylinder 4 and extends into the interior of the storage cylinder 4. There are two circular hole discs 40, which are located inside the storage cylinder 4 and are arranged one above the other.

[0032] The surface of the circular plate 40 is in contact with the inner wall of the storage cylinder 4, the top of the force-bearing frame 45 is located on the upper surface of the elastic rod 44, the top of the force-bearing frame 45 is in contact with the bottom of the pressing ring 32, and the lifting frame 43 is located on the upper surface of the positioning plate 46.

[0033] In use, the injection needle 2 is inserted into the surface of the one-way valve tube 8 at the end of the syringe 1, which facilitates the replacement of the injection needle 2. When the pull rod 6 is pulled to move to the outside of the syringe 1, the pull rod 6 will pull the rubber disc 5 to move. The negative pressure generated by the movement of the rubber disc 5 will be transmitted to the inside of the one-way valve seat 3 to open it. After the one-way valve seat 3 is opened, the medicine in the storage cylinder 4 will enter the inside of the syringe 1. At this time, after the injection needle 2 is inserted into the animal's body, the pull rod 6 is released. The pull rod 6 pushes the rubber disc 5 to move towards the injection needle 2 through the elasticity of the spring 7. At this time, the one-way valve tube 8 is in the open state under the pressure of the rubber disc 5. The medicine can be injected into the animal's body through the connection between the one-way valve tube 8 and the injection needle 2, which is more convenient for injection. When the one-way valve tube 8 is in the open state, the one-way valve seat 3 will be in the closed state, which facilitates the liquid inside the storage cylinder 4 to enter the inside of the syringe 1 for continuous liquid addition. This makes it convenient for the syringe 1 to perform continuous injection operations on animals and improves the efficiency of animal vaccination. After the operator measures the required dosage of medication for the animal, they pull the semicircular frame 23 downwards. The semicircular frame 23 pushes the card plate 27 to separate from the inner wall of the card slot plate 25. At this time, the operator can push the movable frame 21 to move on the surface of the scale plate 20. When the movable frame 21 moves to the corresponding scale, the semicircular frame 23 is released. The semicircular frame 23 will then push the card plate 27 to contact the inner wall of the card slot plate 25, using the card plate 27 to fix the movable frame 21. At the same time, the baffle 26 is moved by the fixing plate 24. When the pull rod 6 is moved, the pull rod 6 will contact the baffle 26, thereby limiting the movement distance of the rubber disc 5. This allows the rubber disc 5 to draw the corresponding liquid medication for injection into the animal, improving the convenience of the syringe 1 during continuous operation. When the operator injects the animal with a vaccine, they only need to adjust the baffle 26 to the corresponding position, and the pull rod 6 will pull the rubber disc 5 to draw the corresponding liquid medication. The operator does not need to frequently calibrate the liquid medication during injection. When medication needs to be drawn, the operator pushes the pressing ring 32 downwards. As the pressing ring 32 moves downwards, it pushes the return spring 34 to contract via the contact plate 33. Simultaneously, the contact plate 33 pushes the top of the inclined plate 31 downwards. The angle of the inclined plate 31 changes during this movement, pushing the pull rod 6 towards the outer end of the syringe 1. This improves the ease with which the pull rod 6 pulls the rubber disc 5 to draw medication. Slightly releasing the pressing ring 32 causes it to move upwards using the elasticity of the return spring 34. At the same time, the pull rod 6 pushes the rubber disc 5 to... The squeezing of the medicine causes the rubber disc 5 to push the air inside the syringe 1 out, preventing residual air in the syringe 1 from harming the animal. After the injection needle 2 is inserted into the animal's body, the pressing ring 32 is completely released. At this time, the lever 6 will push the rubber disc 5 to squeeze the medicine through the elasticity of the return spring 34 and the spring 7, so that the medicine can be automatically injected into the animal's body, improving the convenience of vaccination for animals and reducing the force required for the operator to pull the lever 6 to extract the medicine. The lever 6 is more labor-saving and convenient to use. When the pressing ring 32 moves downward, it pushes the elastic rod 44 downward through the force-bearing frame 45. When the elastic rod 44 moves downward, it pushes the sliding rod 41 downward through the connection between the lifting frame 43 and the bent rod 42. When the sliding rod 41 moves downward, it pushes the circular disc 40 downward inside the storage cylinder 4. When the circular disc 40 moves, it can squeeze and mix the liquid medicine to avoid precipitation. At the same time, when the circular disc 40 moves downward, it provides pressure to the liquid medicine, so that the liquid medicine can stably enter the syringe 1 through the one-way valve seat 3. The positioning plate 46 limits the lifting frame 43 to improve the stability of the lifting frame 43 during movement. The elastic rod 44 has the function of elastic extension, so that the force-bearing frame 45 has the function of downward extension. When the pressing ring 32 moves upward, the elastic spring 47 will pull the circular disc 40 upward, so that the circular disc 40 can follow the pressing ring 32 to move up and down, improving the stability of the liquid supply from the storage cylinder 4 to the syringe 1.
