Description

Technical Field

[0001] The invention relates to the field of animal medicine, in particular to a blood sample collection device for animal disease detection. Background Art

[0002] Animal disease prevention and control centers at all levels across the country monitor and detect the prevention and control of major animal diseases such as foot-and-mouth disease, swine fever, and avian influenza in livestock and poultry in their jurisdictions all year round. Animal quarantine departments also conduct inspections and quarantines on livestock and poultry that are sold, trafficked, and slaughtered. Blood sampling can detect most animal diseases. However, existing blood sampling devices often require operators to cooperate with both hands to complete blood sampling. In this case, it is difficult for operators to effectively control animals alone, so multiple people must cooperate to complete blood sampling; and blood often needs to be collected from multiple tubes in order to fully understand the animal situation.

The present invention provides a technical solution: a blood sample collection device for animal disease detection, comprising a cover body 1, a needle 3, and a blood sampling tube 5. The needle 3 is installed on the cover body 1, and the blood sampling tube 5 can enter the cover body 1. The needle 3 can pierce the upper cover of the blood sampling tube 5 to collect blood. The end of the cover body 1 away from the needle 3 is slidably connected to the sample tube box 6, and a handle 2 is fixedly connected to the bottom of the cover body 1 for easy grasping. The cover body 1 is detachably connected to the needle box 4, and a number of unused needles are stored in the needle box 4. One side of the cover body 1 is rotatably connected to a turntable 9, and the turntable 9 can be disassembled. A number of blood sampling tubes 5 are installed on the turntable 9. A clamp 7 and a lever 8 are arranged in the cover body 1. The blood sampling tube 5 is clamped and moved by the clamp 7. After the blood sampling tube 5 completes blood sampling, the blood sampling tube 5 is pushed by the lever 8 and falls into the sample tube box 6. The turntable 9 is connected to the ratchet 10 and driven to rotate by the ratchet 10. The clamp 7, the lever 8, and the ratchet 10 are all arranged in the cover body 1; The plate 7 is driven by the trigger 201, and the clip 7 pushes the lever 8 and the ratchet 10 to move during the movement; when in use, first prepare, remove the turntable 9 from the cover body 1, and then install a number of blood collection tubes 5 on the turntable 9. After the installation is completed, install the turntable 9 back on the cover body 1, remove the needle box 4, and place a number of needles 3 therein. The inner diameter of the needle box 4 is consistent with the needles 3, that is, the needles 3 can only be arranged vertically in one row in the needle box 4. After placing the needles 3, install the needle box 4 back on the cover body 1, and then install the sample tube box 6 on the cover body 1. The sample tube box 6 can adopt a detachable connection method including but not limited to slot block plug-in. In order to facilitate the removal of the blood collection tube 5, a slot can be opened on the sample tube box 6 so that the blood collection tube 5 can be taken away in time.

At this time, the clip 7 does not drive the lever 8 to move. The clip 7 moves to clamp the blood collection tube 5 and pushes the blood collection tube 5 forward, so that the upper cover of the blood collection tube 5 is pierced by the needle 3, and the blood sample flows into the blood collection tube. In order to facilitate clamping, a groove or a baffle can be provided on the blood collection tube 5 to ensure the stability of the clamping; when the blood collection volume requirement is reached, the trigger 20 is released. 1, the trigger 201 is reset under the action of the spring. During this process, the clip 7 first drives the blood collection tube 5 to retreat. After the blood collection tube 5 retreats to its original position, the clip 7 releases the blood collection tube 5, and the clip 7 continues to retreat. At this time, the clip 7 first passes the position of the lever 8 and drives the lever 8 to move, so that the lever 8 moves the blood collection tube 5, so that the blood collection tube 5 is separated from the turntable 9. The blood collection tube 5 falls to the sample tube box 6 under the action of gravity, and then the clip 7 continues to retreat. The clip 7 drives the ratchet 10 to rotate at a certain angle, the ratchet 10 drives the turntable 9 to rotate, and the turntable 9 drives the blood collection tube 5 on it to rotate, but the blood collection tube 5 does not reach the bottom of the needle 3, so as to prepare for the replacement of the next blood collection tube 5. Repeat the above operation to collect multiple blood samples from the same blood collection object. When the blood collection object is replaced, the ring rack 307 is moved to discard the used needle 3, and the needle box 4 is pressed again to install a new needle 3. At this time, the needle replacement is completed and blood can be collected from the lowered object. When the blood collection is completed, remove the sample tube box 6 and take out the blood collection tube for testing.

The ring sleeve sprocket 305, the ring sleeve gear 306, and the ring sleeve rack 307 are rotatably connected in the cover body 1, and the ring sleeve rack 307 is partially exposed from the cover body 1. A spring is arranged between the ring sleeve rack 307 and the cover body 1. When in use, the operator toggles the ring sleeve rack 307, and while the ring sleeve rack 307 slides and stretches the spring, the ring sleeve rack 307 drives the ring sleeve gear 306 to rotate, and the ring sleeve gear 306 drives the ring sleeve sprocket 305 to rotate, and the two ring sleeve sprockets 305 rotate synchronously through the chain, and the ring sleeve sprocket 305 drives the needle ring sleeve 302 to rotate, and the needle ring sleeve 302 drives the ring sleeve rod 303 connected thereto to rotate, and the ring sleeve rod 303 drives the needle clamp rod 304 to rotate, and the needle clamp rod 304 drives the ring sleeve rod 303 at the other end to rotate, and the ring sleeve rod 303 drives the needle ring sleeve 302 to rotate, so that multiple needle ring sleeves 302 rotate together. The needle ring sleeve 302 drives the needle clamping rod 304 to rotate several circles, and the used needle 3 is pushed out of the cover body 1. When the replacement is completed and discarded, the ring sleeve rack 307 is loosened, and the ring sleeve rack 307 is reset under the action of the spring; when a new needle 3 is replaced, the needle 3 pushes the needle clamping rod 304, so that the needle ring sleeve 302 rotates a certain angle, so that the next needle clamping rod 304 just enters the groove of the needle 3 to clamp the needle 3. At this time, although the ring sleeve rack 307 moves a certain distance, the elastic force of the spring cannot offset the friction between the ring sleeve rack 307 and the cover body 1, so the needle 3 can be stably clamped.

A spring is arranged between the needle box rack 403 and the needle box 4. When the needle box needs to be replaced, the needle box pressure rod 402 is pressed. Since the spring under the needle box rack 403 is larger than the spring stiffness coefficient between the needle box 4 and the needle box sleeve 401, the needle box pressure rod 402 first drives the needle box 4 to move downward. When the needle box 4 moves to the bottom, the needle 3 at the lower end of the needle box 4 is just opposite to the needle ring 301. The needle box pressure rod 402 continues to be pressed, and the needle box pressure rod 402 and the needle box 4 slide relative to each other.
