Description

Technical Field

[0001] This application relates to the field of syringes, and more specifically, to an adjustable syringe for veterinary use. Background Technology

[0002] A veterinarian is a doctor who prevents, diagnoses, and treats diseases in animals. Specifically, a veterinarian is a professional who uses medical methods to promote harmony between the animal's (including wild animals, poultry, livestock, and aquatic animals) body, microorganisms, and the natural environment. A syringe is one of the medical devices used by veterinarians. For example, Chinese patent application number CN202020342888.8 describes a veterinary drug syringe with an adjustable nozzle, comprising a syringe body with a needle attached to its tip. First, because two sliding rods contact the injection site first during injection, and these two sliding rods form a protective structure for the needle, needle breakage due to animal agitation during injection can be prevented. Second, because the needle passes through sterile cotton during injection, and the sliding rods, sterile seat, sterile cotton, and elastic element together form an elastic sliding sterilization structure for the needle, automatic needle sterilization can be achieved.

[0003] However, the above solution still has certain drawbacks: First, the handle and the syringe body are an integrated structure, which is inconvenient to adjust according to the needs of users due to the different sizes of their hands, resulting in low applicability. Second, when injecting different drugs, the injection head needs to be separated from the animal to change the drug, which is cumbersome and reduces its practicality. Utility Model Content

[0004] To overcome the above shortcomings, this application provides an adjustable veterinary syringe, which aims to improve the related technology where the handle and syringe body are integrated into one structure. Since users have different hand sizes, it is inconvenient to adjust according to the needs of use, resulting in low applicability. Secondly, when injecting different drugs, the injection head needs to be separated from the animal to change the drug, which is cumbersome and reduces the practicality of the technology.

[0005] This application provides an adjustable veterinary syringe including an injection component and an adjustment component.

[0006] The injection assembly includes an injection cylinder, a piston rod, a first valve, an injection head, a limiting frame, a knob, a reservoir, and a second valve. The piston rod is slidably connected to the injection cylinder. The first valve is located at one end of the injection cylinder. The injection head communicates with the injection cylinder. The limiting frame is located on both sides of the injection cylinder. The knob is connected through both sides of the limiting frame. Both reservoirs communicate with the injection cylinder. The second valve is located at one end of the reservoir. The adjustment assembly includes a grip plate, an arc-shaped handle, and an elastic retainer. The grip plate is slidably connected to the limiting frame. The knob is threadedly connected to the grip plate. The elastic retainer is fixedly connected to the arc-shaped handle and slidably engaged with the limiting frame.

[0007] In one specific implementation, the limiting frame has several through holes on both sides, and the knob is slidably connected to the through holes.

[0008] In the above implementation process, several through holes are provided on both sides of the limiting frame, which can serve as a connection.

[0009] In one specific implementation, the liquid storage cylinder includes a cylinder body, a cylinder cap, and a connecting tube. The cylinder cap is disposed at one end of the cylinder body, and the connecting tube is disposed at one end of the cylinder body and communicates with the syringe.

[0010] In the above process, the cylinder is used to store the drug, and when the drug inside the cylinder is extracted, the cap is separated from the cylinder.

[0011] In one specific implementation, a connecting block is provided at one end of the grip plate, the connecting block is slidably connected to the limiting frame, a screw hole is provided on one side of the connecting block, and the knob is threadedly connected to the screw hole.

[0012] In the above implementation process, a connecting block is provided at one end of the gripping plate. The connecting block and the screw hole can serve as a connection.

[0013] In one specific implementation, the grip plate has several slots on both sides.

[0014] In the above implementation process, several slots are provided on both sides of the grip plate, which can serve as a locking mechanism.

[0015] In one specific implementation, the elastic card holder includes a fixed block, a spring, and a protruding block. The spring is disposed on both sides of the fixed block, the protruding block is slidably connected to the fixed block, the protruding block is fixedly connected to the spring, and the protruding block is slidably connected to the card slot.

[0016] In the above implementation process, when it is necessary to adjust the position of the arc-shaped handle, by squeezing the protruding block, the protruding block is squeezed to compress the spring and move into the fixed block, so that the protruding block is misaligned with the slot. Then the fixed block can be moved until the spring force pushes the protruding block into the slot at the appropriate position.

[0017] In one specific implementation, a cylinder is provided on one side of the fixing block, and the arc-shaped handle is fixedly connected to the cylinder.

[0018] In the above implementation process, a cylinder is provided on one side of the fixed block, which can serve as a connection.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: First, the piston rod injects the drug inside the syringe. The two reservoirs are used to store different drugs. By closing the first valve and opening the second valve, one or both drugs from the two reservoirs can be drawn out. Then, the first valve is opened again and the second valve is closed, and the drug is injected by the piston rod. The position of the two grip plates can be adjusted by a knob, and the function of the arc-shaped handle can be adjusted by sliding the elastic seat until it is moved to a suitable position. This allows for easy adjustment of the grip plates and arc-shaped handle according to the user's needs, resulting in high applicability. At the same time, different drugs can be injected without separating the injection head from the animal, making it more convenient to use and thus improving its practicality.

[0027] Please see Figure 1-4 This application provides an adjustable veterinary syringe including an injection component 100 and an adjustment component 200.

[0028] Please see Figure 1-2 The injection assembly 100 includes an injection cylinder 110, a piston rod 120, a first valve 130, an injection head 140, a limiting frame 150, a knob 160, a reservoir 170, and a second valve 180. The piston rod 120 is slidably connected to the injection cylinder 110. The first valve 130 is located at one end of the injection cylinder 110. The injection head 140 communicates with the injection cylinder 110. The limiting frame 150 is located on both sides of the injection cylinder 110. The knob 160 passes through and connects to both sides of the limiting frame 150. Both reservoirs 170 communicate with the injection cylinder 110. The second valve 180 is... The liquid storage cylinder 170 is located at one end, and the limiting frame 150 has several through holes 151 on both sides. The knob 160 is slidably connected to the through holes 151. The through holes 151 can serve as a connection. The liquid storage cylinder 170 includes a cylinder body 171, a cylinder cover 172, and a connecting tube 173. The cylinder cover 172 is located at one end of the cylinder body 171, and the connecting tube 173 is located at one end of the cylinder body 171. The connecting tube 173 is connected to the syringe 110. The cylinder body 171 is used to store drugs. When the drugs inside the cylinder body 171 are drawn out, the cylinder cover 172 is separated from the cylinder body 171.

[0029] Please see Figure 1 , Figure 3 and Figure 4The adjustment assembly 200 includes a grip plate 210, an arc-shaped handle 220, and an elastic seat 230. The grip plate 210 is slidably connected to the limiting frame 150, and the knob 160 is threadedly connected to the grip plate 210. The elastic seat 230 is fixedly connected to the arc-shaped handle 220 and slidably engaged with the limiting frame 150. One end of the grip plate 210 is provided with a connecting block 211, which is slidably connected to the limiting frame 150. One side of the connecting block 211 is provided with a screw hole 212, and the knob 160 is threadedly connected to the screw hole 212. The connecting block 211 and the screw hole 212 serve as a connection. Several slots 213 are provided on both sides of the grip plate 210, which serve as a locking mechanism.

[0030] In some specific implementations, the elastic seat 230 includes a fixed block 231, a spring 232, and a protruding block 233. The spring 232 is disposed on both sides of the fixed block 231. The protruding block 233 is slidably connected to the fixed block 231 and fixedly connected to the spring 232. The protruding block 233 is slidably connected to the slot 213. When it is necessary to adjust the position of the arc-shaped handle 220, the protruding block 233 is squeezed, causing the protruding block 233 to squeeze the spring 232 and move into the fixed block 231, causing the protruding block 233 to be misaligned with the slot 213. Then the fixed block 231 can be moved until the elastic force of the spring 232 pushes the protruding block 233 to slide into the slot 213 at the appropriate position. A cylinder 2311 is provided on one side of the fixed block 231. The arc-shaped handle 220 is fixedly connected to the cylinder 2311. The cylinder 2311 can serve as a connection.

[0031] The working principle of this adjustable veterinary syringe is as follows: During use, the piston rod 120 injects the medication inside the syringe 110. Two reservoirs 170 store different medications. By closing the first valve 130 and opening the second valve 180, one or both medications can be drawn from the two reservoirs 170. Reopening the first valve 130 and closing the second valve 180 allows the medication to be injected via the piston rod 120. When drawing medication from the syringe 171, the cap 172 is separated from the syringe 171. The position of the two grip plates 210 can be adjusted using the knob 160. When the curved handle 220 is in position, by squeezing the protrusion 233, the protrusion 233 compresses the spring 232 and moves into the fixed block 231, causing the protrusion 233 to be misaligned with the slot 213. Then the fixed block 231 can be moved until the elastic force of the spring 232 pushes the protrusion 233 into the slot 213 in the appropriate position. This makes it easy to adjust the grip plate 210 and the curved handle 220 according to the user's needs, making it highly adaptable. At the same time, different drugs can be injected without separating the injection head 140 from the animal, making it more convenient to use and thus improving its practicality.
