Description

Technical Field

[0001] The utility model belongs to the technical field of livestock infusion, and in particular relates to a livestock infusion fixing device capable of preventing excessively deep puncture. Background Art

[0002] Livestock sometimes need intravenous infusion treatment when they are sick. However, livestock are difficult to control and tend to move around during the infusion process, which can easily cause the infusion needle to puncture too deep or fall off. Therefore, the infusion needle or the livestock's body needs to be fixed during the livestock infusion process.

[0003] The Chinese patent authorization announcement number CN207545252U discloses a livestock infusion fixing device for animal husbandry and veterinary medicine, including a supporting base plate, a groove is provided at the bottom of the supporting base plate, a bearing is fixedly connected to the top of the inner wall of the groove, the inner wall of the bearing is fixedly connected to one end of a rotating rod, the other end of the rotating rod is fixedly connected to the top of a movable pulley, and the movable pulley passes through the groove and extends to the outside of the groove. The livestock infusion fixing device for animal husbandry and veterinary medicine, through the arrangement of a supporting frame, an electric push rod, a connecting plate, a limit clamp block, a slider and a slide groove, can better fix the livestock during infusion, thus solving the problem of manually fixing the livestock for infusion, so that the livestock will not shake during infusion, avoiding the problem of secondary injury to the livestock caused by the infusion needle being inserted off-center when the livestock shakes, thus saving manpower and time for infusing the livestock.

[0004] The livestock infusion fixing device provided by the above patent is used to fix the body of the livestock, not to fix the infusion needle. When veterinarians perform infusion treatment on livestock, they often insert the infusion needle into the vein at the neck of the livestock. The reason for this is that the vein at the neck of the livestock is easy to find, and the neck has a smaller range of motion than the limbs, so the infusion needle is more stable when inserted into the neck. However, during the infusion process, the back-and-forth movement of the livestock's neck or the livestock's neck rubbing against foreign objects may cause the infusion needle to puncture too deeply or cause the infusion needle to fall off, affecting the normal infusion of the livestock. At present, there is no infusion needle fixing device suitable for livestock on the market. Utility Model Content
