Description
Technical Field
[0001] The utility model relates to the technical field of animal medical treatment, in particular to a long-distance large-dose injection device for large animals. Background Art
[0002] In wildlife veterinary clinics, drug injections are often required in large animals. However, existing syringes have limited injection doses and require close contact with the animal, posing significant safety risks to animal care and veterinary staff. Therefore, developing a needle device that can accurately deliver large doses to large animals over long distances and automatically detach after injection is crucial. Utility Model Content
[0003] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide a long-distance large-dose injection device for large animals.
[0004] The technical solution adopted by the utility model to solve the technical problem is: a long-distance large-dose injection device for large animals, comprising:
[0005] Fixing clip, injection needle, infusion tube and long pole;
[0006] The two ends of the fixing clamp are respectively a first end and a second end, the second end of the fixing clamp is connected to the end of the long rod, the first end of the fixing clamp clamps and fixes the injection needle, one end of the infusion tube is connected to the injection needle, and the other end of the infusion tube is connected to the syringe;
[0007] The fixing clamp includes a first clamp body and a second clamp body, the middle portion of the first clamp body and the middle portion of the second clamp body are connected via a rotating shaft, and the second end of the first clamp body is fixedly connected to the end portion of the long rod;
[0008] An elastic member is provided between the first jaw body and the second jaw body, and the elastic member presses the first jaw body and the second jaw body together to keep the first end of the fixing clamp in an open state;
[0009] The second end of the second clamp body is provided with a lock buckle. When the injection needle is fixed to the first end of the fixing clamp, the second end of the second clamp body approaches the second end of the first clamp body, and the lock buckle is fastened to the second end of the first clamp body, so that the first end of the fixing clamp remains in a clamped state.
[0010] An unlocking rod is provided on one side of the fixing clamp, and the unlocking rod is slidably connected along one side of the fixing clamp, the first end of the unlocking rod is facing the first end of the fixing clamp, and the second end of the unlocking rod is facing the lock buckle. When the injection needle penetrates the animal, the first end of the unlocking rod is pressed against the surface of the animal and pushed toward one end of the lock buckle, and the second end of the unlocking rod contacts the lock buckle and pushes the lock buckle open, so that the fixing clamp is released from the fastening state and the injection needle is separated from the fixing clamp.
[0011] The main working principle is as follows: An operator draws the liquid medication to be injected into a large syringe (which can be one or more), then connects the syringe to the other end of the injection hose, fills the infusion tube with liquid medication, and places the injection needle connected to the infusion tube on the first end of the fixed clamp, ensuring that the injection needle is stably placed in it. Before the fixed clamp clamps the injection needle, the elastic member pushes the first end of the first clamp body and the second end of the second clamp body away from each other, leaving the first end of the fixed clamp in an open position. Then, the operator pulls the second end of the first clamp body and the second end of the second clamp body, causing the second end of the first clamp body and the second end of the second clamp body to rotate toward each other along the rotation axis. Similarly, the first end of the first clamp body and the second end of the second clamp body move closer together, clamping the injection needle. At this time, the locking catch of the second clamp body is operated to engage the locking catch of the second end of the second clamp body with the second end of the first clamp body, keeping the fixed clamp in a clamped state, thereby firmly fixing the injection needle. Then, one end of the long rod is connected to the second end of the fixed clamp to ensure a secure connection.
[0012] During operation, the operator holds the other end of the long pole and aims the entire device at the large animal to be injected, while maintaining a certain distance. Due to the design of the long pole, the operator can perform the injection while being away from the animal, which improves safety.
[0013] When the injection needle penetrates the animal's body, one end of the unlocking lever presses against the animal's skin surface. As the injection progresses, the unlocking lever, pushed by the animal, begins to slide along one side of the retaining clamp and gradually moves toward the lock buckle. When the unlocking lever contacts the lock buckle, it pushes the lock buckle open, releasing the lock buckle from the second end of the first clamp body, thereby releasing the retaining clamp from its locked state. Once the retaining clamp is unlocked, the pressure on the elastic member is eliminated, causing the elastic member to elastically recover, pushing the first end of the first clamp body and the first end of the second clamp body apart again. The injection needle is no longer clamped by the retaining clamp and is automatically separated from the retaining clamp. The injection needle remains in the animal's body, and another operator applies pressure to the syringe connected to the back of the infusion tube to inject a large dose of medicine. After the medicine in one syringe is injected, another syringe containing the medicine is replaced. When all the medicine is injected into the infusion tube, the remaining medicine in the infusion tube is pressed into the animal's body by inhaled air or injection water. After the injection is completed, the operator pulls the infusion tube to remove the injection needle from the animal's body to complete the injection of the medicine. In summary, the utility model realizes large-dose injection of long-distance and large animals through the combined design of a fixing clamp, an injection needle, an infusion tube and a long rod, and automatically detaches the injection needle after the injection, thereby improving the accuracy and safety of the injection and simplifying the operation process.
[0014] Preferably, a sliding ring is provided on one side of the fixing clamp, the unlocking rod is inserted into the sliding ring, and the unlocking rod moves back and forth along the sliding ring.
[0015] Preferably, the number of the sliding ring is not less than one, and not less than one sliding ring is arranged along the moving direction of the unlocking rod.
[0016] Preferably, the two ends of the unlocking rod are respectively a first tightening part and a second tightening part, and the end of the first tightening part and the end of the second tightening part both extend outward away from the fixing clip, and the first tightening part is located at the end of the unlocking rod facing the injection needle, and is pressed against the animal; the second tightening part is located at the end of the unlocking rod facing the lock buckle, and is pressed against the lock buckle.
[0017] Preferably, a fixing hole is provided at the second end of the second pliers body, and the lock buckle is provided with a fixing block, which passes through the fixing hole and extends outward, and the width of the fixing hole is greater than the width of the fixing block, and the extended part of the fixing block is provided with a limit block, and the width of the limit block is greater than the width of the fixing hole.
[0018] Preferably, a locking hole is provided at the second end of the first clamp body, and a locking groove is provided on the side of the lock buckle facing the injection needle. The lock buckle passes through the locking hole, and the locking groove and the locking hole are clamped to each other, thereby achieving mutual fastening between the first clamp body and the second clamp body.
[0019] Preferably, the length of the locking hole is greater than the width of the lock buckle, and the width of the locking hole is not less than the thickness of the lock buckle.
[0020] Preferably, the first end of the second clamp body is bent toward the side facing away from the first clamp body, and when the second clamp body and the first clamp body clamp the injection needle, the first end of the second clamp body remains parallel to the first end of the first clamp body.
[0021] Preferably, when the injection needle is clamped and fixed by the fixing clip, the needle tip of the injection needle extends to the outside of the first end of the fixing clip.
[0022] Compared with the prior art, the beneficial effects of the present invention are:
[0023] The long rod design of this utility model allows the operator to perform injections while standing away from the animal, thus avoiding potential dangers caused by sudden animal movement or attack. The combination of the retaining clip and locking catch ensures the stability of the injection needle during the injection process, improving injection accuracy. The unlocking lever design automatically releases the needle after the needle penetrates the animal, allowing it to remain in the animal's body while the retaining clip can be easily retrieved. This feature avoids the inconvenience and risks associated with manual needle removal in traditional injection methods.
[0024] In summary, the present invention provides a safe, accurate and efficient long-distance large-dose injection device for large animals, which brings significant convenience and improvement to the work in related fields. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of this application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0034] Example 1
[0035] This embodiment discloses a long-distance large-dose injection device for large animals, such as Figure 1-Figure 5As shown, the clamp comprises a fixing clamp 1, an injection needle 2, and a long rod 3. The fixing clamp 1 is designed with two ends: a first end 10 for clamping the injection needle 2; and a second end 11 connected to the end of the long rod 3. A lock 13 is provided at the second end 11 of the fixing clamp 1. When the injection needle 2 is placed on the first end 10 and clamped, the lock 13 fastens the two sides of the fixing clamp 1, thereby securing the injection needle 2. A release lever 12 is also provided on one side of the fixing clamp 1. The release lever 12 can slide along one side of the fixing clamp 1. One end of the release lever 12 faces the first end 10, and the other end faces the lock 13. When the injection needle 2 penetrates the animal, one end of the release lever 12 presses against the surface of the animal and is pushed toward one end of the lock 13. The release lever 12 contacts the lock 13 and pushes it open, releasing the locking state of the fixing clamp 1 and allowing the injection needle 2 to detach from the fixing clamp 1.
[0036] During operation, an operator draws the liquid medicine to be injected into a large syringe (which can be one or more), then connects the syringe 4 to the other end of the injection hose, fills the infusion tube 5 with the liquid medicine, places the injection needle 2 connected to the infusion tube 5 on the first end of the fixing clamp 1, and ensures that the injection needle 2 is stably placed therein. Before the fixing clamp 1 clamps the injection needle 2 during operation, due to the tightening effect of the elastic member, the first end of the first clamp body 16 and the second end of the second clamp body 15 are separated from each other, so that the first end of the fixing clamp 1 is in an open state as a whole. Subsequently, the operator pulls the second end of the first clamp body 16 and the second end of the second clamp body 15, causing the second ends of the first clamp body 16 and the second ends of the second clamp body 15 to rotate closer to each other along the rotation axis. Similarly, the first end of the first clamp body 16 and the second end of the second clamp body 15 are closer to each other and the injection needle 2 is clamped. At this time, the lock 13 of the second clamp body 15 is operated to snap the lock 13 of the second end of the second clamp body 15 onto the second end of the first clamp body 16, so that the entire fixing clamp 1 remains clamped, thereby firmly fixing the injection needle 2. Then, one end of the long rod 3 is connected to the second end of the fixing clamp 1 to ensure a stable connection.
[0037] During operation, the operator holds the other end of the long rod 3 and aims the entire device at the large animal to be injected, and keeps a certain distance. Due to the design of the long rod 3, the operator can perform the injection when away from the animal, which improves safety.
[0038] When the injection needle 2 penetrates the animal's body, one end of the unlocking lever 12 presses against the animal's skin surface. As the injection progresses, the unlocking lever 12 receives the animal's thrust and begins to slide along one side of the fixing clamp 1, gradually moving toward the end of the lock catch 13. When the unlocking lever 12 contacts the lock catch 13, the unlocking lever 12 pushes the lock catch 13 open, and the lock catch 13 releases the engagement with the second end of the first clamp body 16, thereby releasing the locked state of the fixing clamp 1. Once the fixing clamp 1 is unlocked, the pressure on the elastic member is eliminated, and the elastic member elastically recovers, pushing the first end of the first clamp body 16 and the first end of the second clamp body 15 apart again. The injection needle 2 is no longer clamped by the fixing clamp 1, and is automatically separated from the fixing clamp 1. The injection needle 2 remains in the animal's body, and another operator applies pressure to the syringe 4 connected to the back of the infusion tube 5 to inject a large dose of medicine. After the medicine in one syringe 4 is injected, another syringe 4 containing medicine is replaced. When all the medicine is injected into the infusion tube 5, the remaining medicine in the infusion tube 5 is pressed into the animal's body by inhaled air or injection water. After the injection is completed, the operator pulls the infusion tube 5 to remove the needle 2 from the animal's body to complete the injection of the medicine. In summary, the utility model realizes long-distance, large-dose injection of large animals through the combined design of the fixing clamp 1, the injection needle 2, the infusion tube 5 and the long rod 3, and automatically detaches the injection needle 2 after the injection, thereby improving the accuracy and safety of the injection and simplifying the operation process.
[0039] In some optional embodiments, a sliding ring 14 is provided on one side of the fixing clamp 1, and the unlocking rod 12 is inserted into the sliding ring 14, and the unlocking rod 12 can reciprocate along the sliding ring 14. This design can ensure the stability of the unlocking rod 12 during movement and prevent it from deviating from the predetermined trajectory.
[0040] In some optional embodiments, the number of sliding rings 14 is not less than one, and these sliding rings 14 are arranged along the moving direction of the unlocking rod 12. The design of multiple sliding rings 14 can further increase the stability of the movement of the unlocking rod 12, ensuring that it can slide smoothly and unlock when pushed by an animal.
[0041] In some optional embodiments, the unlocking lever 12 is configured with a first pressing portion 120 and a second pressing portion 121 at each end. The first pressing portion 120 faces the first end 10 and is used to press against the surface of the animal. The second pressing portion 121 faces the latch 13 and is used to press against the latch 13 and push it open. This design ensures that the unlocking lever 12 can effectively transmit force when pushed by the animal, while also utilizing the elastic force of the spring 6 to achieve the unlocking function.
[0042] In some optional embodiments, the retaining clamp 1 comprises a first jaw 16 and a second jaw 15, which are connected at their midpoints by a rotating shaft. The second end 11 of the first jaw 16 is fixedly connected to the end of the long rod 3. This design allows the retaining clamp 1 to be securely connected to the long rod 3 while maintaining a certain degree of flexibility.
[0043] In some optional embodiments, such as Figure 5 As shown, the second end 11 of the second pliers 15 is provided with a fixing hole 150, and the lock buckle 13 is provided with a fixing block 131. The fixing block 131 passes through the fixing hole 150 and extends outward. The width of the fixing hole 150 is greater than the width of the fixing block 131. The extension of the fixing block 131 is provided with a limit block 132. The width of the limit block 132 is greater than the width of the fixing hole 150. The limit block 132 can be connected to the fixing block 131 by threads, and can also be welded. After the fixing block 131 passes through the fixing hole 150, it is directly welded to the extension of the fixing block 131. The width of the fixing hole 150 is greater than the width of the fixing block 131, which ensures that the fixing block 131 has a certain range of movement in the fixing hole 150. During the unlocking process of the lock buckle 13, the fixing block 131 moves in the fixing block 131, which can further unlock the lock buckle 13. At the same time, since the width of the limiting block 132 is greater than the width of the fixing hole 150, it ensures that the fixing block 131 will not fall off from the fixing hole 150 during the movement in the fixing hole 150.
[0044] In some optional embodiments, a locking hole 161 is provided at the second end 11 of the first clamp body 16, and a locking groove 130 is provided on the side of the locking buckle 13 facing the injection needle 2. After the locking buckle 13 passes through the locking hole 161, the locking groove 130 and the locking hole 161 are locked together, thereby achieving the mutual fastening between the first clamp body 16 and the second clamp body 15. This design ensures that the fixing clamp 1 can firmly clamp the injection needle 2, preventing it from loosening or falling off during the injection process.
[0045] In some optional embodiments, the length of the locking hole 161 is designed to be greater than the width of the lock buckle 13, while the width of the locking hole is not less than the thickness of the lock buckle 13. This design allows the lock buckle 13 to easily pass through the locking hole 161 and be locked therewith, while also ensuring the stability of the lock buckle 13 in the locking hole 161.
[0046] In some optional embodiments, the first end 10 of the second clamp body 15 is bent toward the side facing away from the first clamp body 16. When the second clamp body 15 and the first clamp body 16 clamp the injection needle 2, the first end 10 of the second clamp body 15 remains parallel to the first end 10 of the first clamp body 16. This design allows the fixing clamp 1 to clamp the injection needle 2 more securely and also facilitates the placement and removal of the injection needle 2.
[0047] In some optional embodiments, after the injection needle 2 is clamped and secured by the retaining clip 1, the tip of the injection needle 2 extends beyond the first end 10 of the retaining clip 1. This design ensures that the needle can smoothly penetrate the animal's body for injection. The above description is merely a preferred embodiment of the present invention and does not constitute any formal limitation on the present invention. Therefore, any modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
