Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a veterinary injection device. Background Art

[0002] Veterinary syringes are a common livestock medical device. They are mainly used to help veterinarians treat sick livestock. Usually, liquid medicine can be injected into the body of livestock through a needle to provide treatment for sick livestock and restore them to health.

[0003] During the injection process of large livestock, the livestock often resist violently due to the pain stimulation, which makes the needle break easily, not only damaging the syringe but also causing harm to the livestock. Therefore, it is necessary to fix the livestock in advance during the injection process of large livestock. Announcement No. CN110946668B provides a veterinary treatment injection fixation device, but this fixation device is not only large in size and inconvenient to transport, but also cumbersome to operate, and may also cause livestock injuries during the fixation process.

[0004] Therefore, in view of the above problems, a veterinary injection device is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims at the deficiencies of the prior art and develops a veterinary injection device. The utility model can perform injection treatment on livestock and can prevent needle displacement and damage caused by livestock's resistance due to stimulation.

[0006] The technical solution of the utility model to solve the technical problem is: a veterinary injection device, including a needle tube, the needle tube is detachably arranged in an auxiliary tube, the needle tube and the auxiliary tube are coaxially arranged, the needle tube and the auxiliary tube are connected by a limiting structure, and the auxiliary tube is provided with a locking structure and a fixing structure.

[0007] The needle tube is fixed to the livestock through an auxiliary tube to prevent the livestock from violently resisting due to pain stimulation during the injection process, causing the needle tube to fall off or bend. A limiting structure is set between the needle tube and the auxiliary tube to prevent the needle tube from shifting during the injection process, and a locking mechanism helps to install the needle tube and the auxiliary tube.

[0008] Preferably, the limiting structure includes a limiting groove, a limiting ring and a push plate. The limiting groove is symmetrically arranged on the upper part of the auxiliary tube. The push plate is slidably connected in the limiting groove. The push plate is connected to the needle tube. The needle tube is slidably connected in the limiting ring. The limiting ring is coaxially arranged in the auxiliary tube. The limiting ring is connected to the auxiliary tube through multiple connecting rods.

[0009] The push plates on both sides of the needle tube are slidably connected in the limiting grooves, the rotation of the needle tube is limited by the limiting grooves, and the deviation of the needle tube is limited by the limiting rings.

[0010] Preferably, the locking structure includes a mounting block, a locking hole and a bevel block. The mounting block is arranged on the outside of the auxiliary tube. The mounting blocks are symmetrically arranged on both sides of the lower part of the limiting groove. A locking hole is arranged on the side of the mounting block close to the limiting groove. The bevel block is slidably connected in the locking hole. The bevel block has an inclined surface facing upward. The lower end of the bevel block is located on the push plate. The bevel block is connected to the reset structure.

[0011] During injection, the needle tube is pushed downward along the limit groove. When the needle tip is inserted into the skin of the livestock, the push plate squeezes the inclined surface of the inclined block, and the inclined block is forced to move toward the locking hole. After the push plate passes over the inclined block, the inclined block is reset under the drive of the reset structure. At this time, the movement of the push plate is restricted to achieve a locking effect. Even if the livestock resists due to pain, the needle tube cannot be separated from the auxiliary tube.

The tension spring is located between the mounting block and the retaining ring.

[0013] When the inclined block moves toward the limit groove, the limit shaft drives the tension spring to continue to stretch. After the push plate passes over the inclined block, the tension spring contracts and drives the limit shaft and the inclined block to move as a whole, thereby achieving a reset effect.

[0014] Preferably, the fixing structure includes an annular cushion, a mounting groove, a connecting head and a fixing belt. The annular cushion is arranged at the lower end of the auxiliary tube. The mounting grooves are symmetrically arranged on both sides of the annular cushion. The connecting head is arranged in the mounting groove. The connecting head is connected to the auxiliary tube.
