Abstract
Description
Technical Field
[0001] This utility model relates to the field of anesthesia devices, specifically a veterinary anesthesia device. Background Technology
[0002] Veterinarians are professionals who use medical methods to promote the harmony between the organisms of animals (including wild animals, poultry, livestock, and aquatic animals) and their microorganisms and natural environment. The discipline that supports the veterinary profession is veterinary science, which, in addition to directly ensuring livestock production, has expanded into fields such as public health, environmental protection, human disease models, and the pharmaceutical industry.
[0003] Existing patent CN217014331U discloses a veterinary remote anesthesia device, including an anesthesia needle, an anesthesia component located within the needle, and a remote launching component for launching the anesthesia component. This veterinary remote anesthesia device places the anesthesia component in a chamber on one side of the launching tube. The anesthetist blows gas into the launching tube through a silicone nozzle, propelling the anesthesia component. A helical groove within the launching tube applies lateral pressure, causing the anesthesia component to rotate in the same direction as the helical groove. Until it leaves the launching tube, it maintains stable flight throughout its effective range. The balancing feathers minimize the impact of air on the anesthesia component, maintaining its trajectory and making it easier to hit the target for anesthesia.
[0004] However, this anesthesia device still has some drawbacks. When loading the anesthetic, the locking mechanism needs to be disassembled, and after loading, the sliding plug needs to be pushed into the anesthesia needle tube, which makes the operation cumbersome. In addition, most of the existing needle tubes and needles are connected by a mating connection, which can detach when the pressure inside the needle tube is too high, thus affecting the use of the device. At the same time, when using the existing device, the friction between the silicone sleeve and the needle can affect the needle insertion effect, resulting in incomplete needle insertion and affecting the anesthesia effect.
[0005] Based on this, a veterinary anesthesia device is now provided that eliminates the drawbacks of existing devices. Utility Model Content
[0006] The purpose of this invention is to provide a veterinary anesthesia device to solve the problems of cumbersome anesthetic loading, unstable needle and syringe connection, and poor needle insertion effect in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A veterinary anesthesia device includes a needle tube with a sliding groove on the left side and opening grooves on both sides of the sliding groove. A spring is installed inside the needle tube on the left side.
[0009] A connecting assembly is installed on the right side of the needle tube. The connecting assembly includes a support ring, which is installed on the right side of the needle tube. A threaded ring is installed in the middle of one side of the needle tube. A sealing ring is also installed on one side of the support ring. A needle insertion assembly is threadedly connected to the outer side of the threaded ring.
[0010] The sliding groove has a sliding connection with a pushing component.
[0011] Based on the above technical solutions, this utility model also provides the following optional technical solutions:
[0012] In one alternative: the outer side of the threaded ring is fitted with threads for connection, and the sealing ring is made of nitrile rubber.
[0013] In one alternative embodiment: the needle insertion assembly includes a connecting tube threaded to the outside of a threaded ring, a needle is mounted on one side of the connecting tube, a recessed groove is provided on the left side of the needle, the diameter of the recessed groove is smaller than the diameter of the needle, an outlet hole is opened on the top right side of the needle, and a silicone sleeve is slidably connected to the outside of the needle.
[0014] In one alternative: four anti-dislodgement components are installed on the right side of the needle.
[0015] In one alternative: the anti-detachment component is composed of a barb.
[0016] In one alternative: the pushing assembly includes a push rod slidably connected inside a sliding groove, a sliding plug is installed on the right side of the push rod, and a pushing sleeve is installed on the left side of the push rod.
[0017] In one alternative: the inner side of the push rod is rotatably connected to a limit assembly.
[0018] In one alternative: the limiting assembly includes a rotating ring rotatably connected to the inside of the push rod, and two limiting blocks are installed on both sides of the rotating ring.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. This utility model uses the connecting component and the needle insertion component together to connect the needle and the needle tube through threads, avoiding the problem of easy detachment in conventional insertion installation, and improving the stability of the connection. At the same time, the needle insertion component has a recessed groove design. When the silicone sleeve enters the recessed groove, the diameter is reduced, which makes the silicone sleeve slide smoothly in the recessed groove, avoiding the problem of high resistance affecting the needle insertion effect.
[0021] 2. This utility model avoids the problem of the needle being squeezed out by the anesthetic fluid during injection by using the anti-drop component, thus improving the anesthetic effect of the device. By using the push component and the limiting component together, after the anesthetic is filled, the rotating ring is rotated and the limiting block is used to limit the position, so as to push the silicone sleeve to the position of the liquid outlet for sealing, thus improving the convenience of adding anesthetic to the device.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0028] In one embodiment, such as Figures 1-4 As shown, a veterinary anesthesia device includes: a needle tube 1, a sliding groove 11 on the left side of the needle tube 1, opening grooves 12 on both sides of the sliding groove 11, and a spring 13 installed inside the left side of the needle tube 1.
[0029] A connecting assembly is installed on the right side of the needle tube 1. The connecting assembly includes a support ring 14, which is installed on the right side of the needle tube 1. A threaded ring 15 is installed in the middle of one side of the needle tube 1. A sealing ring 16 is also installed on one side of the support ring 14. A needle insertion assembly is threadedly connected to the outer side of the threaded ring 15.
[0030] The sliding groove 11 has a sliding connection with a pushing component.
[0031] In this embodiment, the spring 13 inside the needle tube 1 resets, thereby driving the pushing component to push the anesthetic drug out. The support ring 14 supports the threaded ring 15. The threaded connection between the threaded ring 15 and the needle insertion component improves the stability of the connection. The sealing ring 16 seals the connection to avoid leakage.
[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, the outer side of the threaded ring 15 is fitted with threads for connection, and the sealing ring 16 is made of nitrile rubber, which seals the gaps.
[0033] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the needle insertion assembly includes a connecting tube 2, which is threaded to the outside of a threaded ring 15. A needle 21 is installed on one side of the connecting tube 2. A recessed groove 22 is provided on the left side of the needle 21. The diameter of the recessed groove 22 is smaller than the diameter of the needle 21. An outlet hole 23 is opened on the top right side of the needle 21. A silicone sleeve 24 is slidably connected to the outside of the needle 21. The silicone sleeve 24 seals the outlet hole 23. The design of the recessed groove 22 reduces the resistance of the silicone sleeve 24 after it leaves the outlet hole 23, thus avoiding the problem of excessive resistance affecting the needle insertion effect.
[0034] In one embodiment, such as Figure 1 and Figure 3 As shown, four anti-drop components are installed on the right side of the needle 21, which prevent the needle from falling off.
[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, the anti-dislodgement component is composed of a barb 25. The design of the barb 25 avoids the problem of the needle 21 being pushed off due to the injection of anesthetic after insertion.
[0036] In one embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the pushing assembly includes a push rod 3, which is slidably connected inside the sliding groove 11. A sliding plug 31 is installed on the right side of the push rod 3, and a pushing sleeve 32 is installed on the left side of the push rod 3. The connection between the push rod 3 and the sliding plug 31 facilitates the filling of anesthetic by driving the device.
[0037] In one embodiment, such as Figure 1 and Figure 4 As shown, a limiting component is rotatably connected to one side of the push rod 3, and the push rod 3 is limited by the limiting component.
[0038] In one embodiment, such as Figure 1 and Figure 4 As shown, the limiting component includes a rotating ring 33, which is rotatably connected to the inside of the push rod 3. Two limiting blocks 34 are installed on both sides of the rotating ring 33. By rotating the rotating ring 33, the limiting blocks 34 are rotated, which prevents the push rod 3 from moving due to the spring 13, thereby facilitating the adjustment of the position of the silicone sleeve 24.
[0039] The above embodiment discloses a veterinary anesthesia device. By pulling the push rod 3, the sliding plug 31 moves to the left inside the needle tube 1, causing the spring 13 to contract and draw anesthetic into the needle tube 1. Rotating the rotating ring 33 causes the limiting block 34 to rotate, pressing against the left side of the needle tube 1, thus limiting the push rod 3 and preventing the spring 13 from automatically rebounding and causing the anesthetic to flow out. This pushes the silicone sleeve 24 to the outside of the outlet hole 23, sealing the outlet hole 23. Rotating the rotating ring 33 causes the limiting block 34 to move to the position corresponding to the opening groove 12. During use, the device... After the needle 21 is inserted, the silicone sleeve 24 is pushed away from the liquid outlet 23, allowing it to enter the interior of the recessed groove 22. The smaller diameter of the recessed groove 22 reduces the resistance of the silicone sleeve 24, avoiding the problem of poor needle insertion due to excessive resistance. When the liquid outlet 23 is opened, the spring 13 pushes the sliding plug 31 to discharge the anesthetic from the liquid outlet 23, thus completing the injection. The threaded connection between the connecting tube 2 and the threaded ring 15 improves the firmness of the connection between the needle tube 1 and the needle 21. The sealing ring 16 seals the gap, preventing the anesthetic from leaking and improving the practicality of the device.
[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
