Description

Technical Field

[0001] This invention belongs to the field of animal husbandry technology, specifically an animal vaccination device. Background Technology

[0002] Animal vaccination is a core means of preventing animal infectious diseases, ensuring animal health, public health safety, and the economic benefits of animal husbandry and aquaculture. By introducing a "safe form of pathogen (or its components)," the animal's immune system is activated to produce specific resistance. Specialized vaccination devices are used when administering animal vaccines.

[0003] A Chinese patent with publication number CN116602786B discloses an animal vaccination device, which includes a vehicle body. It uses limiting rod one and limiting rod two and a rubber panel on them to limit the chicks. Under the action of the positioning frame, the position of the drip bottle can be adjusted to ensure that the distance between the drip bottle outlet and the chick's eyes is within the calibrated limit value.

[0004] The above-mentioned technical solution achieves precise positioning of animals by pre-limiting them during use, which facilitates vaccination. However, the equipment is large in size, and the animal needs to be fixed for each vaccination. After vaccination, the animal needs to be separated from the device, which consumes a lot of time and results in low vaccination efficiency.

[0005] Therefore, the present invention provides an animal vaccination device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown in the embodiment of the present invention, an animal vaccination device includes a medicine box 1. A positioning frame 11 is fixed at the bottom of the medicine box 1. A drug extraction tube 121 is provided inside the positioning frame 11. A needle 127 is installed at the bottom of the drug extraction tube 121. A piston 125 is provided inside the drug extraction tube 121. A push rod 126 is fixed at the top of the piston 125. An movable hole 14 is opened in the middle of the medicine box 1. Fixing plates 142 are fixed on both sides inside the movable hole 14. Lifting rods 122 are fixed on both sides at the top of the drug extraction tube 121. A lifting plate 124 is fixed in the middle of the lifting rod 122. A first spring 123 is fixed at the top of the lifting plate 124. The top of the first spring 123 is fixedly connected to the bottom of the fixing plate 142. A triggering component is provided below the lifting plate 124. Positioning is achieved by pressing the positioning frame 11 onto the surface of the animal's skin, and by triggering the first spring 123 to push the lifting plate 124, thereby causing the needle 127 to be inserted into the animal's body. In animal husbandry, to prevent animals from contracting serious diseases, they are vaccinated at a young age to prevent death from severe illnesses. During vaccination, staff inject the vaccine into the animal. Before vaccination, the inside of the medicine box 1 is disinfected, and then the vaccine is poured into it. The staff then picks up the medicine box 1 and aligns the bottom of the positioning frame 11 with the skin area to be injected. The positioning frame 11 is pressed against the animal's skin surface, at which point the first spring 123 is compressed. Simultaneously, the triggering component blocks the bottom of the lifting plate 124. The staff then activates the triggering component, separating it from the lifting plate 124. At this point, the first spring 123 is compressed. 3. The spring force pushes the lifting plate 124 downward, which in turn drives the lifting rod 122 downward. The lifting rod 122 pushes the drug extraction tube 121 downward, which in turn pushes the needle 127 downward, allowing the needle 127 to quickly penetrate the animal's body. The spring force allows the needle 127 to penetrate faster, reducing the pain experienced by the animal during injection. Then, the staff presses the push rod 126 downward, which pushes the piston 125 to squeeze the medicine inside the drug extraction tube 121 and inject it into the animal's body through the needle 127. Depending on the animal's size, the injection time lasts for 5-10 seconds. After the injection is completed, the entire medicine box 1 is pulled to remove the needle 127 from the animal's body. At this point, a vaccination is completed. This method allows for rapid vaccination of animals and improves vaccination efficiency.

[0023] like Figures 1 to 4 As shown, the triggering component includes sliding grooves 143 on both sides of the movable hole 14. A telescopic rod 131 is slidably connected inside the sliding groove 143. A locking plate 132 is fixed to one end of the telescopic rod 131. The locking plate 132 can be placed at the bottom end of the lifting plate 124. A push plate 13 is fixed to the other end of the telescopic rod 131. When the needle 127 is not inserted into the animal's body, the first spring 123 remains compressed. At this time, the first spring 123 pushes the lifting plate 124 to press against the top of the clamping plate 132, thereby keeping the needle 127 in a ready-to-fire state. When the needle 127 needs to be inserted into the animal's body, the push plates 13 on both sides are pressed at the same time. The push plates 13 push the telescopic rod 131 to move the clamping plate 132 away from the bottom of the lifting plate 124, thereby releasing the first spring 123 and driving the needle 127 into the animal's body. Pressing only one side of the push plates 13 on both sides will not trigger the first spring 123, which can reduce the risk of accidentally triggering the first spring 123 and causing the needle 127 to extend during the handling of the medicine box 1, thus affecting the safety of the staff.

[0024] like Figures 1 to 4 As shown, a lifting frame 12 is fixed to the top of the lifting rod 122, and a push rod 126 is located in the middle of the lifting frame 12; After the needle 127 is removed from the animal, the aspiration tube 121 and the needle 127 need to be reset. At this time, pull the lifting frame 12. The lifting frame 12 drives the needle 127 to retract into the positioning frame 11 through the lifting rod 122. At the same time, the first spring 123 is compressed, and the locking plate 132 is moved to the bottom of the lifting plate 124 to lock the lifting plate 124 again, which is more convenient for subsequent inoculation.

[0025] like Figures 1 to 4 As shown, a slope 134 is provided on one side of the card plate 132, and the top of the lifting plate 124 can contact the surface of the slope 134. When the lifting frame 12 is pulled upward, it causes the lifting plate 124 to rise, and the lifting plate 124 pushes the clamping plate 132 to one side through the inclined surface 134. When the lifting plate 124 is pulled upward, it will contact the surface of the inclined plane 134. The inclined plane 134 pushes the clamping plate 132 to move, so that the clamping plate 132 automatically makes way for the lifting plate 124. Then the clamping plate 132 moves to the bottom of the lifting plate 124 to limit the lifting plate 124, making it easier for the clamping plate 132 to return to the bottom of the lifting plate 124.

[0026] like Figures 1 to 4 As shown, a second spring 133 is fixed to one side of the card plate 132, and the other end of the second spring 133 is fixedly connected to the inner wall of the sliding groove 143. When the lifting plate 124 pushes the clamping plate 132 to move through the inclined plane 134, the second spring 133 is compressed. When the lifting plate 124 moves above the clamping plate 132, the elastic force of the second spring 133 pushes the clamping plate 132 to automatically reset, thereby making the clamping plate 132 automatically move below the lifting plate 124, so that the clamping plate 132 automatically limits the bottom of the lifting plate 124.

[0027] like Figures 1 to 3 As shown, a liquid inlet 128 is provided on one side of the bottom end of the drug drawing tube 121. The end of the liquid inlet 128 is connected to an infusion tube 141. The top end of the infusion tube 141 is connected to the inside of the medicine tank 1. A one-way valve plate is provided inside the liquid inlet 128 that only opens when liquid is drawn in. A one-way valve plate is provided at the bottom end of the drug drawing tube 121 that only opens when liquid is discharged. After use, the drug extraction tube 121 is reset. At this time, the piston 125 is at the bottom of the drug extraction tube 121. Then, the push rod 126 is pulled upward to drive the piston 125 to rise from the inside of the drug extraction tube 121. During this process, the one-way valve at the bottom of the drug extraction tube 121 is closed, and the one-way valve at the inlet 128 is opened. The vaccine liquid inside the medicine box 1 can be drawn into the inside of the drug extraction tube 121 through the infusion tube 141, so as to quickly replenish the vaccine liquid into the inside of the drug extraction tube 121.

[0028] like Figures 1 to 5As shown, housings 2 are fixed on both sides inside the positioning frame 11. An alcohol swab 23 is provided inside the housing 2 and is attached to the outside of the needle 127. When the needle 127 is returned to the inside of the positioning frame 11, the needle 127 needs to be disinfected. At this time, the alcohol swab 23 comes into contact with the outside of the needle 127. The alcohol inside the alcohol swab 23 can disinfect the needle 127, thereby achieving rapid disinfection for subsequent use.

[0029] like Figures 1 to 6 As shown, an unwinding shaft 21 is rotatably connected to the upper part of the housing 2. One end of the alcohol swab 23 is wound around the outside of the unwinding shaft 21. A take-up shaft 22 is rotatably connected to the lower part of the housing 2. The other end of the alcohol swab 23 is wound around the outside of the take-up shaft 22. A guide roller 24 is rotatably connected to the side of the housing 2 near the needle 127 via a support frame. The alcohol swab 23 is attached to the outside of the guide roller 24. A connecting plate 129 is fixed to one side of the lifting rod 122. A take-up wheel 221 is provided on one side of the take-up shaft 22. A pull rope 224 is wound inside the take-up wheel 221. The top end of the pull rope 224 is fixedly connected to the connecting plate 129. When the lifting rod 122 is raised, it drives the needle 127 to pass through the alcohol cotton strip 23, and the connecting plate 129 pulls the pull rope 224 to cause the winding wheel 221 to drive the winding shaft 22 to wind up the alcohol cotton strip 23. When disinfecting the needle 127 with alcohol swab 23, if only one area of ​​the alcohol swab 23 is used to contact the needle 127, the disinfection effect will be worse in subsequent use. Therefore, when the lifting rod 122 is raised, it will pull the pull rope 224 through the connecting plate 129. The pull rope 224 drives the winding wheel 221 to rotate. The winding wheel 221 drives the winding shaft 22 to wind up the alcohol swab 23. The alcohol swab 23 can continuously roll while wiping the outside of the needle 127 through the guide roller 24, so that different areas of the alcohol swab 23 are used each time the needle 127 is wiped, thereby improving the disinfection effect of the alcohol swab 23 on the needle 127.

[0030] like Figures 1 to 6 As shown, a connecting disc 223 is fixed to the end of the take-up shaft 22 near the take-up wheel 221. The connecting disc 223 is connected to the take-up wheel 221 through a ratchet structure. A coil spring 222 is fixed to one side of the take-up wheel 221, and the other side of the coil spring 222 is fixedly connected to the housing 2. When the pull rope 224 pulls the winding wheel 221, the ratchet and ratchet teeth engage; when the coil spring 222 drives the winding wheel 221 to reset, the ratchet and ratchet teeth disengage. When the needle 127 moves downward and inserts into the animal's body, the coil spring 222 drives the take-up wheel 221 to rotate in the opposite direction to take up the pull rope 224. At the same time, the ratchet teeth of the take-up wheel 221 and the connecting disc 223 separate, which can prevent the take-up shaft 22 from reversing and unwinding the used alcohol swab 23. This achieves automatic reset of the pull rope 224, which is convenient for subsequent take-up of the alcohol swab 23.

[0031] like Figures 1 to 7 As shown, a rotating disk 211 is fixed to the end of the unwinding shaft 21. Multiple slots 212 are equally spaced on one side of the rotating disk 211. A positioning plate 213 is provided on one side of the rotating disk 211. The positioning plate 213 is fixedly connected to the housing 2. Multiple third springs 214 are equally spaced inside the positioning plate 213. A steel ball 215 is fixed to one side of the third spring 214. The steel ball 215 can be inserted into the slot 212. If the alcohol swab 23 is loose during unwinding of the unwinding shaft 21, it will affect the wiping effect of the alcohol swab 23 on the needle 127. In order to prevent the alcohol swab 23 from being loose, it needs to be tightened. A rotating disk 211 is fixed at the end of the unwinding shaft 21. When the unwinding shaft 21 is pulled and rotated, the unwinding shaft 21 drives the slot 212 to rotate through the rotating disk 211. At this time, the edge of the slot 212 squeezes the steel ball 215, so that the steel ball 215 is squeezed into the interior of the positioning plate 213. At the same time, the third spring 214 is squeezed. At this time, the friction force of the third spring 214 pushing the steel ball 215 to contact the rotating disk 211 can provide a certain damping for the unwinding of the unwinding shaft 21, so that the unwinding shaft 21 keeps the alcohol swab 23 taut, thus preventing the alcohol swab 23 from being loose and affecting the wiping effect on the needle 127.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
