Description

Technical Field

[0001] This utility model relates to the field of vaccine injection technology, and in particular to an auxiliary injection device for animal and veterinary vaccines. Background Technology

[0002] In the field of animal husbandry and veterinary medicine, vaccination is a key link in the prevention and control of animal diseases, and therefore a vaccine injection auxiliary device for animal husbandry and veterinary medicine is needed.

[0003] Existing livestock, such as pigs, have different body sizes at different ages, and pigs of different sizes need to be injected with different doses of vaccines. For example, small pigs are injected with a dose of 15ml, while large pigs are injected with a dose of 25ml. However, conventional injection methods mainly rely on manual push-type syringes, which require manual adjustment of the piston to the appropriate position with the scale each time. However, the piston position is not precise each time, resulting in insufficient dose control accuracy. To solve the above problems, this application proposes an auxiliary injection device for livestock and veterinary vaccines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary injection device for animal husbandry and veterinary vaccines. By inserting the insert rod and the adsorption block into different ports, the vaccine injection dosage can be adjusted, and the amount of vaccine injected each time is equal, resulting in high precision in vaccine injection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A livestock and veterinary vaccine auxiliary injection device includes a first arc-shaped plate, a second arc-shaped plate rotatably connected to the first arc-shaped plate, a reset mechanism between the first and second arc-shaped plates, a fixed arc-shaped plate fixedly connected to the end of the first arc-shaped plate near the second arc-shaped plate, a plurality of insertion ports extending through the fixed arc-shaped plate, a rod inserted into one of the insertion ports, an adsorption block fixedly connected to the end of the rod, a piston cylinder fixedly connected to the end of the second arc-shaped plate away from the first arc-shaped plate, a piston slidably connected to the piston cylinder, a connecting rod fixedly connected to the side wall of the piston, the connecting rod extending through the second arc-shaped plate and slidably connected to it, a limiting rod fixedly connected to the connecting rod coaxially, two limiting grooves formed on the first arc-shaped plate, the front and rear ends of the limiting rod respectively extending through the corresponding limiting grooves, a connecting pipe fixedly connected to the top of the piston cylinder, a vaccine storage box fixedly connected to the top of the connecting pipe, and a liquid outlet pipe fixedly connected to the end of the piston cylinder away from the second arc-shaped plate, a needle inserted into the end of the liquid outlet pipe.

[0007] Preferably, the reset mechanism includes a fixed rod fixedly connected to the first arc-shaped plate, the fixed rod passing through the second arc-shaped plate and rotatably connected to it, and two torsion springs sleeved on the outer wall of the fixed rod, with each torsion spring having its two ends fixedly connected to the first arc-shaped plate and the second arc-shaped plate respectively.

[0008] Preferably, the second arc-shaped plate has a through opening, and the fixed arc-shaped plate is provided through the through opening.

[0009] Preferably, the plurality of the sockets are distributed at equal intervals, the fixed arc plate is made of iron, and the adsorption block is made of magnet.

[0010] Preferably, the vaccine storage box includes a lower shell and an upper shell, the lower shell and the upper shell are threaded together, and an arc-shaped block is fixedly connected to the top of the upper shell.

[0011] Preferably, a first check valve is fixedly connected to the outer wall of the connecting pipe, and a second check valve is fixedly connected to the outer wall of the outlet pipe.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] Staff can adjust the insertion of the rod into different ports. The suction force of the suction block firmly attaches the rod and the suction block to the fixed arc plate. This allows the staff to adjust the distance between the first and second arc plates and the range of the piston within the piston cylinder, thereby adjusting the amount of vaccine injected each time. Inserting the rod into the fixed port ensures that the amount of vaccine injected each time is equal.

[0014] In summary, by inserting the plunger and adsorption block into different ports, the vaccine injection dosage can be adjusted, and the amount of vaccine injected each time is equal, resulting in high precision in vaccine injection. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A livestock and veterinary vaccine auxiliary injection device includes a first arc plate 1, a second arc plate 2 rotatably connected to the first arc plate 1, and a reset mechanism between the first arc plate 1 and the second arc plate 2. The reset mechanism includes a fixed rod 3 fixedly connected to the first arc plate 1, the fixed rod 3 passing through the second arc plate 2 and rotatably connected to it, and two torsion springs 4 sleeved on the outer wall of the fixed rod 3. The two ends of each torsion spring 4 are fixedly connected to the first arc plate 1 and the second arc plate 2 respectively. The torsion springs 4 can make the first arc plate 1 and the second arc plate 2 move away from each other, and the torsion springs 4 have a large torque, which can drive the piston 10 to move inside the piston cylinder 9.

[0021] A fixed arc plate 5 is fixedly connected to one end of the first arc plate 1 near the second arc plate 2. The second arc plate 2 has a through opening, and the fixed arc plate 5 has multiple through holes 6. A rod 7 is inserted into one of the through holes 6, and an adsorption block 8 is fixedly connected to the end of the rod 7. The multiple through holes 6 are evenly spaced. The fixed arc plate 5 is made of iron, and the adsorption block 8 is made of magnet. The adsorption force of the magnet can firmly install the adsorption block 8 and the rod 7 on the fixed arc plate 5. By inserting the rod 7 into different through holes 6, the final distance of the piston 10 in the piston cylinder 9 can be adjusted, thereby adjusting the injection volume of the vaccine and allowing vaccination of livestock of different sizes, such as pigs.

[0022] A piston cylinder 9 is fixedly connected to the end of the second arc plate 2 away from the first arc plate 1. A piston 10 is provided inside the piston cylinder 9 and is slidably connected to it. The piston cylinder 9 is provided with scale lines. A connecting rod 11 is fixedly connected to the side wall of the piston 10. The connecting rod 11 passes through the second arc plate 2 and is slidably connected to it. A limiting rod 12 is provided through the connecting rod 11 and is coaxially fixedly connected to it. Two limiting grooves 13 are opened on the first arc plate 1. The front and rear ends of the limiting rod 12 are respectively set through the corresponding limiting grooves 13. By sliding the limiting rod 12 in the limiting grooves 13, the connecting rod 11 and the piston 10 can slide left and right.

[0023] A connecting pipe 15 is fixedly connected to the top of the piston cylinder 9. A first one-way valve 16 is fixedly connected to the outer wall of the connecting pipe 15. The first one-way valve 16 allows unidirectional flow, allowing the vaccine in the vaccine storage box 14 to be injected into the piston cylinder 9. The top of the connecting pipe 15 is fixedly connected to the vaccine storage box 14. The vaccine storage box 14 includes a lower shell and an upper shell. The lower shell and the upper shell are threaded together to replenish the vaccine. An arc-shaped block is fixedly connected to the top of the upper shell. A liquid outlet pipe 17 is fixedly connected to the end of the piston cylinder 9 away from the second arc-shaped plate 2. A second one-way valve 18 is fixedly connected to the outer wall of the liquid outlet pipe 17, allowing unidirectional flow of air and liquid, so that liquid can only be injected from the piston cylinder 9 into the needle 19. A needle 19 is inserted into the end of the liquid outlet pipe 17.

[0024] In this invention, the operator first pinches the arc-shaped block to rotate and open the upper shell, pouring the vaccine liquid into the lower shell. Finally, the upper shell is rotated to seal the two shells. When it is necessary to inject the vaccine into the pig, the operator holds the device, twisting the first arc-shaped plate 1 with their thumb and pinching the second arc-shaped plate 2 with their other four fingers. The pinching motion of the hand moves the first arc-shaped plate 1 and the second arc-shaped plate 2 closer together. During this process, the torsion spring 4 is engaged, and the proximity of the first arc-shaped plate 1 and the second arc-shaped plate 2 moves the connecting rod 11 and the piston 10. The piston 10 moves within the piston cylinder 9, injecting the vaccine through the needle 19. After the vaccine injection is completed, the first arc-shaped plate 1 and the second arc-shaped plate 2 are released. Under the action of the stored torsion spring 4, the first arc-shaped plate 1 and the second arc-shaped plate 2 move away from each other until... The insertion rod 7 and the adsorption block 8 abut against the outer wall of the second arc plate 2, limiting the first arc plate 1 and the second arc plate 2. During this process, the piston 10 slides inside the piston cylinder 9 and moves towards the second arc plate 2, injecting the vaccine liquid in the vaccine storage box 14 into the piston cylinder 9 through the connecting tube 15, ready for the next vaccine injection. The needle 19 can be replaced before injection. The staff can adjust the insertion rod 7 into different insertion ports 6. The adsorption force of the adsorption block 8 firmly adsorbs the insertion rod 7 and the adsorption block 8 onto the fixed arc plate 5, thereby adjusting the distance between the first arc plate 1 and the second arc plate 2, adjusting the range of the piston 10 within the piston cylinder 9, and thus adjusting the amount of vaccine injected each time. Inserting the insertion rod 7 into the fixed insertion port 6 ensures that the amount of vaccine injected each time is equal.
