Technical Field
[0001] This disclosure relates to the field of epidemic prevention technology, and in particular to an injection gun that automatically disinfects needles. Background Technology
[0002] In livestock farms, vaccination is necessary to prevent the spread of infectious diseases. A large number of animals are often raised on the same farm at once, and it's uncertain whether individual animals carry pathogens or what pathogens they may carry. To prevent cross-infection between different animals, traditional vaccination procedures require frequent needle changes, which significantly reduces efficiency and also increases immunization costs due to needle replacements. Utility Model Content
[0003] By using the device disclosed herein, needles can be automatically disinfected during use, which improves injection efficiency and reduces immunization costs.
[0004] To address the aforementioned technical problems, this disclosure provides an automatic needle sterilization injection gun. The needle includes a mounting end and an injection end. The injection gun comprises a gun body, a connector, and a sterilization device connected in sequence. The mounting end is connected to the connector, and the injection end extends into the sterilization device. The sterilization device includes:
[0005] The first tube has a connecting end at one end and a limiting end at the other end. The connecting end is connected to the connector, and the limiting end extends toward the axis of the first tube to form a reduced diameter section.
[0006] The second tube has a first end at one end and a second end at the other. The first end is slidably disposed within the first tube, and a protrusion is provided on the outer wall surface of the first end. The protrusion cooperates with the reduced-diameter portion to restrict the second tube from sliding out of the first tube. An end cap is detachably connected to the second end, and the end cap has a first through hole. The second tube has a receiving cavity inside capable of accommodating the sterilization component, and a second through hole is provided on the wall surface of the receiving cavity opposite to the end cap.
[0007] An elastic element is disposed within the first tube and is used to provide a restoring force to the second tube, causing the second tube to return to its reset state; wherein...
[0008] As the second tube gradually slides from the reset state into the first tube, the needle tip can slide out from the receiving cavity through the first through hole.
[0009] In some embodiments, the first tube further includes a first element detachably connected to the first tube at one end remote from the limiting end.
[0010] In some embodiments, the elastic element is a spring.
[0011] In some embodiments, a first slot is provided on the first part at the end that contacts the elastic member, and a second slot is provided on the first end at the point where it contacts the elastic member, and both ends of the elastic member are respectively engaged in the first slot and the second slot.
[0012] In some embodiments, the elastic element is fixedly connected to the first element or the second tube.
[0013] In some embodiments, the first tube is a reducing tube, wherein the cross-sectional area of the reducing tube decreases from the connecting end to the limiting end.
[0014] In some embodiments, the reducing pipe includes 2 to 5 sections of pipe with different diameters connected in sequence.
[0015] In some embodiments, an opening is provided on the side wall of the receiving cavity.
[0016] In some embodiments, there are two openings, namely a first opening and a second opening, wherein the diameter of the first opening is larger than the diameter of the second opening.
[0017] In some embodiments, the end cap is connected to the second pipe thread.
[0018] The present disclosure provides an injection gun for automatic needle disinfection, wherein a second tube is slidably connected to a first tube, and the second end of the second tube extends out of the first tube. When injecting an animal, the second end is pressed against the animal's skin, and external force is applied to the injection gun, causing the second tube to retract into the first tube, exposing the needle. A receiving cavity is provided in the second tube to accommodate the disinfection component. After injection, under the action of an elastic element, the second tube gradually returns to its unpressed state. During the transition of the second tube's state, the disinfection component in the receiving cavity disinfects the needle, that is, the part of the needle that came into contact with the animal. This improves injection efficiency and reduces immunization costs. Attached Figure Description

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.
[0033] The following is in conjunction with the appendix Figures 1-6 The apparatus involved in this disclosure will be described.
[0034] In some embodiments, the injection gun for automatic needle sterilization includes a needle 20 comprising a mounting end and an injection end. The injection gun includes a gun body 11, a connector 13, and a sterilization device connected in sequence. The mounting end is connected to the connector 13, and the injection end extends into the sterilization device. The sterilization device includes:
[0035] The first tube 30 has a connecting end at one end and a limiting end at the other end. The connecting end is connected to the connecting member 13, and the limiting end extends toward the axis of the first tube 30 to form a reduced diameter section.
[0036] The second tube 40 has a first end at one end and a second end at the other. The first end is slidably disposed within the first tube 30. A protrusion 43 is provided on the outer wall of the first end, which cooperates with the reduced diameter portion to restrict the second tube 40 from sliding out of the first tube 30. An end cap 44 is detachably connected to the second end, and the end cap 44 has a first through hole. The second tube 40 has a receiving cavity 45 inside, capable of accommodating the sterilization component. A second through hole is provided on the wall of the receiving cavity 45 opposite to the end cap 44.
[0037] An elastic element 50, disposed within the first tube 30, provides a restoring force to the second tube 40, causing the second tube 40 to return to its reset state; wherein...
[0038] When the second tube 40 gradually slides from the reset state into the first tube 30, the needle tip can slide out from the receiving cavity 45 through the first through hole.
[0039] In the diagram, 111 represents the measuring tube. When injecting an animal, the second end presses against the animal's skin. Upon applying external force, the second tube contracts into the first tube, initiating the injection. By incorporating a cavity within the second tube to hold a sterilizing element, the second tube gradually returns to its unstressed state after injection, thanks to an elastic element. During this transition, the sterilizing element in the cavity disinfects the needle. This eliminates the need for frequent needle replacements, significantly improving work efficiency and reducing immunization costs.
[0040] In some embodiments, the first tube 30 further includes a first element 33, which is detachably connected to the first tube 30 at one end away from the limiting end. This design prevents the second tube from detaching from the first tube when the sterilization device is removed.
[0041] This application does not impose any special limitations on the elastic element; those skilled in the art can make reasonable selections according to the needs of use. For example, in some embodiments, the elastic element 50 is a spring. In some embodiments, a first slot is provided on the first element 33 at the end in contact with the elastic element 50, and a second slot is provided on the first end at the point of contact with the elastic element 50. Both ends of the elastic element 50 are respectively engaged in the first slot and the second slot. This structural design, by appropriately limiting the elastic element, can further increase the stability of the device operation, improve the smoothness of the device operation, and at the same time prevent the elastic element 50 from falling out of the device.
[0042] To prevent parts from falling off during disassembly, in some embodiments, the elastic element 50 is fixedly connected to the first element 33 or the second tube 40.
[0043] To appropriately reduce the size of the device and save raw materials, in some embodiments, the first pipe 30 is a reducing pipe, wherein the cross-sectional area of the reducing pipe decreases from the connecting end to the limiting end. The number of pipe segments of different diameters in the reducing pipe can be selected according to actual needs. In some embodiments, the reducing pipe includes 2 to 5 pipe segments of different diameters connected sequentially. This structural design not only makes the equipment more compact but also saves certain raw materials, thereby reducing the cost of raw material consumption, and making the device lighter.
[0044] As the injection process continues, the sterilization effect of the sterilized component in the receiving cavity 45 may gradually decrease. In some embodiments, an opening is provided on the side wall of the receiving cavity 45. By providing the opening, sterilizing agent can be directly added through the opening as needed, that is, sterilizing agent can be added without removing the end cap 44, so that the sterilized component maintains a good sterilization effect for a long time. In some embodiments, there are two openings, namely a first opening and a second opening, the diameter of the first opening is larger than the diameter of the second opening. The first opening serves as a sterilizing agent replenishment hole, and the second opening serves as a sterilizing agent outflow hole. The different hole diameters ensure sufficient contact between the sterilizing agent and the sterilized component.
[0045] This application does not impose any special limitations on the connection methods between the various components. Those skilled in the art can make reasonable choices according to actual usage needs, such as threaded connections, snap-fit connections, etc. In some embodiments, the end cap 44 is threadedly connected to the second tube 40.
[0046] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
[0047] While specific embodiments of this disclosure have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of this disclosure. Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this disclosure. In particular, as long as there is no structural conflict, the technical features mentioned in the various embodiments can be combined in any manner.
