AI Technical Summary
The existing injection methods of pig herds have problems such as pustules, a high proportion of needle breakage, and a difficult long-distance injection of complex pens. This is mainly due to irregular disinfection before injection, the problem of needle breakage and needle curve caused by the rigid connection between the syringe and the pig herd, and the difficulty of accurately removing needles caused by the injection site being far away from the operator.
A veterinary injection needle was designed, using the method of adding a handle and a sponge sleeve to the injection end. The colored disinfectant is absorbed in the sponge sleeve, and disinfection and marking are completed simultaneously during injection to ensure that the injection position and disinfection position are consistent. At the same time, a hose for extension is installed at the end of the needle, which solves the problem of long-distance injection and reduces the chance of breaking and bending the needle through soft connections.
Synchronous disinfection and labeling of the disinfectant in the sponge sleeve during injection is reduced, which reduces the pustule problem caused by bacterial infection; the hose connection achieves long-distance injection, and reduces the problem of broken needles and bent needles caused by stress movement of pigs, improving the accuracy and efficiency of injection.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0046] The core of the utility model is to provide a veterinary injection needle. Another core of the utility model is to provide a veterinary syringe including the veterinary injection needle.
[0047] Please refer to Figure 1 , Figure 1 A veterinary injection needle, comprising:
[0048] The needle end 1 comprises a handle 101 for holding, a needle 103 fixed to the handle 101, and a sponge cover 102 covering the needle 103, wherein the sponge cover 102 can be compressed backward to leak out the needle 103;
[0049] A hose 3 connected to the drug inlet end of the needle 103.
[0050] When performing an injection, first connect the hose 3 to the liquid medicine delivery device, hold the handle 101 to perform the needle insertion action of the needle end 1, wherein the sponge cover 102 should be pre-absorbed with a colored disinfectant, such as iodine tincture, during the needle insertion process, the injection position is disinfected and marked, ensuring that the injection position and the disinfection position are unified, and there will be no problem of only disinfection and missing injection or missing marking after injection;
[0051] After the injection is completed, the handle 101 is released, and the drug delivery device is remotely controlled to deliver the drug. The drug enters the needle 103 through the hose 3 and then enters the pig's body to complete the injection. Afterwards, the hose 3 can be pulled or the handle 101 can be held to remove the needle.
[0052] During the acupuncture, the needle 103 needs to pierce the sponge cover 102. At this time, the disinfectant in the sponge cover 102 can disinfect the needle 103, thereby reducing the cross-infection problem caused by repeated use of the needle 103. At the same time, during the acupuncture, after the needle 103 pierces the pig's epidermis, it will squeeze the sponge cover 102 backward to deform and compress, and can squeeze out part of the disinfectant in the sponge cover 102, thereby ensuring the disinfection effect of the injection position, and avoiding the problem of incomplete disinfection of the injection position caused by the reduction of the disinfectant content at the front end of the sponge cover 102 after repeated use. At the same time, since the sponge cover 102 wraps the needle 103, the needle 103 comes out of the sponge cover 102 during injection, and the position where the needle 103 pierces the pig's skin must contact the sponge cover 102, thereby ensuring that the injection position is consistent with the disinfection position and the marking position, and ensuring that the injection position is marked synchronously, and there will be no problems of wrong marking or missing marking.
[0053] It is worth noting that there is no limitation on the fixing method of the needle 103, the sponge cover 102 and the handle 101, and there is no limitation on the connection method of the needle 103 and the hose 3. That is, any form of the fixing method of the needle 103, the sponge cover 102 and the handle 101, and the connection method of the needle 103 and the hose 3 should be protected by this application.
[0054] like Figure 1 and Figure 2 In some embodiments, the end of the handle 101 is provided with:
[0055] A clamping plate 1012 for fixing the sponge cover 102;
[0056] A limiting plate 1011 for limiting the position of the sponge cover 102;
[0057] The sponge sleeve 102 is sleeved on the outside of the clamping plate 1012 , and the end of the sponge sleeve 102 abuts against the limiting plate 1011 for limiting.
[0058] In this embodiment, the sponge sleeve 102 is sleeved on the outer circumference of the clamping disk 1012 and fixed by an interference fit between the two. At the same time, the end of the sponge sleeve 102 is limited by the limiting disk 1011 to prevent the sponge sleeve 102 from moving to the rear end after being squeezed and deformed during the acupuncture process, thereby ensuring the stability of its position.
[0059] In some embodiments, the sponge cover 102 is directly bonded to the handle 101 with glue or tied from the outside with a fixing ring, which can also avoid the problem of the sponge cover 102 and the handle 101 being detached or relatively displaced, and also falls within the scope of protection of the present application.
[0060] When replacing the needle 103, it is only necessary to detach the sponge cover 102 from the front end to expose the needle 103, thereby replacing the needle.
[0061] In some embodiments, a mounting cylinder 1013 is disposed inside the handle 101 , and a Luer head that is connected to both the needle 103 and the hose 3 is fixedly disposed inside the mounting cylinder 1013 .
[0062] In this embodiment, the handle 101 is not provided with a channel for delivering the drug solution, and is only used for holding and fixing the needle 103. The needle 103 can be used alone after being separated from the handle 101, and a standard Luer head can be used, thereby reducing equipment mold opening costs and lowering production costs.
[0063] The handle 101 , the mounting cylinder 1013 and the needle 103 are coaxially arranged, and the hose 3 passes through the cavity at the axis of the handle 101 .
[0064] The needle 103 is arranged coaxially with the handle 101. When injecting, the operator holds the needle in the same way as a traditional rigidly connected syringe, which is convenient for the operator to use. Passing the hose 3 through the hollow area of the handle 101 can prevent the hose 3 from being accidentally squeezed during the injection and avoid bending of the hose 3 at the Luer head to avoid breakage there.
[0065] See also Figure 3 and Figure 4 In another embodiment, a medicine delivery channel is provided inside the handle 101, and one end of the medicine delivery channel connected to the needle 103 is provided with:
[0066] A Luer head connected to the needle 103;
[0067] A Luer lock 1015 for locking the needle 103;
[0068] The other end of the medicine delivery channel is provided with a pagoda head 1014 for connecting the hose 3.
[0069] That is, the drug delivery channel is integrated inside the handle 101, and the front end of the handle 101 is integrated with a Luer head connected to the needle 103, and the rear end is integrated with a pagoda head 1014 connected to the hose 3, that is, the handle 101 is used as a part of the drug liquid transmission process, and at the same time, a Luer lock 1015 is embedded in the handle 101 to lock the needle 103, thereby preventing the needle 103 from being separated from the Luer head during the injection process. At the same time, the design of the pagoda head 1014 is also to prevent the handle 101 from being separated from the hose 3. In some embodiments, the pagoda head 1014 is replaced by a Luer head, which also belongs to the protection scope of the present application. However, compared with the raised structure at the end of the pagoda head 1014, the anti-detachment performance of the ordinary Luer head is reduced, which is not conducive to pulling the hose 3 to remove the needle after the injection is completed. During the process, the hose 3 may be separated from the handle 101, while the needle 103 is still in the pig's skin.
[0070] In some embodiments, the gripping portion of the handle 101 is provided with friction patterns, and the friction patterns are bamboo-jointed protrusions arranged along the axis of the handle 101;
[0071] The purpose of setting friction patterns on the surface of the handle 101 is to increase the anti-slip performance. During the acupuncture process, the main force is the force along the axial direction. Adding bamboo node protrusions can effectively increase the axial friction force. Similarly, setting other forms of friction patterns such as knurling patterns should also fall within the protection scope of this application.
[0072] See also Figure 1 and Figure 3 The needle 103 is completely wrapped by the sponge sleeve 102 or partially wrapped at the root.
[0073] There are many schemes for designing the position relationship between the needle 103 and the sponge cover 102. In some embodiments, the needle 103 is completely wrapped by the sponge cover 102 to avoid contact between the needle 103 and the outside and reduce the chance of contamination. At the same time, when the needle is inserted, the sponge cover 102 contacts the injection position first to complete the disinfection. Then, the needle 103 can penetrate the pig's skin only after passing through the sponge cover 102. Before penetrating the pig's skin, the needle 103 passes through the sponge cover 102. The needle 103 is contacted with the disinfectant in the sponge cover 102, and the needle 103 is disinfected once. During the process, the sponge cover 102 can be compressed and retreated. Here, the sponge cover 102 is preferably a low-density sponge, which has a small rebound force after deformation and will not pull out the needle 103. When the needle is pulled out, the sponge cover 102 can automatically restore its original shape, and the needle 103 retracts into the sponge cover 102. During the retraction process, the needle 103 is contacted with the disinfectant in the sponge cover 102 again, and the secondary disinfection of the needle 103 is completed.
[0074] In other embodiments, the root of the needle 103 is partially wrapped by the sponge cover 102, such as Figure 1 , the needle tip of the needle 103 is partially exposed outside the sponge cover 102. Compared with the previous embodiment, this embodiment can clearly sense the position of the needle in actual operation to ensure the accuracy of the needle position. However, since the needle is exposed to the air for a long time and the sponge cover 102 cannot directly sterilize the needle tip, the needle tip should be kept clean and sterile before injection, or the needle tip should be sterilized separately before the injection.
[0075] When the needle end 1 of this embodiment is used for acupuncture, the needle tip first penetrates the pig's skin, and then the sponge cover 102 contacts the injection position. As the needle 103 penetrates deeper, the sponge cover 102 is compressed and retreats. During the process, the injection position and the part of the needle 103 wrapped by the sponge cover 102 are disinfected. After the acupuncture is completed, the clamping force of the pig's subcutaneous muscles on the needle 103 is used to ensure that the needle 103 remains in the muscle layer. At this time, the handle 101 is released and the drug delivery device is pushed at the distal end to complete the drug injection. During the process, the drug injection device and the needle end 1 are softly connected by a hose 3 to minimize the interference of the pig's stress movement on the drug injection, and reduce drug waste and problems such as broken and fallen needles.
[0076] A veterinary injection device, comprising:
[0077] The above-mentioned veterinary injection needles;
[0078] An injection end 2 connected to a free end of a hose 3;
[0079] The injection end 2 is a disposable syringe or a continuous syringe.
[0080] This embodiment includes all the technical solutions of the above-mentioned veterinary injection needle and has all the technical effects of the above-mentioned technical solutions, which will not be elaborated here.
[0081] At the same time, the injection end 2 uses a disposable syringe, which can reduce the mutual interference between drugs during multiple injections. For the injection of the same drug, a continuous syringe is used to improve the injection efficiency and reduce the injection cost.
[0082] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0083] The above is a detailed introduction to a veterinary injection needle and a veterinary injection device provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
