Abstract
Description
Technical Field
[0001] This application belongs to the field of blood collection equipment technology, specifically a blood collection detection device. Background Technology
[0002] In the testing and related experiments of swine fever live vaccines, porcine circovirus disease vaccines, and porcine pseudorabies vaccines, blood is frequently drawn from the anterior vena cava of experimental pigs, and serum is separated from the whole blood to detect the antibody levels. Typically, the restraint method for piglets involves one restraint person standing or squatting on the ground or a table, using one hand to hold the pig's two hind legs, bending them downwards or lifting them vertically upwards to control the hindquarters from struggling, and using the other hand to hold the pig's foreleg on the same side and lift it vertically upwards to expose one side of the chest. Another restraint person stands or squats on the opposite side of the pig, using one hand to hold the pig's foreleg on the same side and lift it vertically upwards to expose the other side of the chest, and using the other hand to press down on the pig's jaw to control the head from struggling.
[0003] Current technology requires the pig's body to remain in a straight line and symmetrical on both sides during blood collection. This facilitates the exposure and symmetry of the two anterior chest pits, making it easier to collect blood from the anterior vena cava. However, during the blood collection process, the personnel restraining the experimental pigs cannot free their hands to assist with blood collection or pass items. The entire blood collection process, including restraining the experimental pigs, requires at least four people. For pigs weighing over 40 kg, which are larger, even more people are needed for blood collection, making the blood collection and testing time-consuming and laborious, thus affecting the usability of the product. Utility Model Content
[0004] The purpose of this application is to address the aforementioned issues that during blood collection, the pig's body needs to remain in a straight line and symmetrical on both sides to facilitate exposure and symmetry of the two anterior chest pits, which is more conducive to blood collection from the anterior vena cava. Furthermore, during blood collection, personnel restraining the experimental pigs cannot free their hands to assist with blood collection or pass items, requiring at least four people for the entire process, including restraining the experimental pigs. For pigs weighing over 40 kg, which are larger, even more personnel are needed, leading to time-consuming and labor-intensive blood collection and testing, thus affecting usability. Therefore, this application provides a blood collection and testing device.

The movement of the moving block drives the horizontal plate to move, and the movement of the horizontal plate drives the clamping plate to move. The movement of the clamping plate then drives the pad plate to move and clamp the animal body on both sides. After that, the blood collection tube is pulled, and at this time the clamping block moves into the spring groove, and the blood collection tube is released from fixation. Then, blood is collected from the animal body, which solves the problem of difficulty in blood collection to a certain extent.

[0010] By adopting the above technical solution and setting four support legs, the base plate can be stably supported, reducing the occurrence of base plate swaying.
[0011] In a preferred embodiment, a hanging plate is fixedly fitted on the surface of the blood collection tube. The hanging plate is circular in shape and is placed above the U-shaped clamp.
[0012] By adopting the above technical solution and setting a hanging plate, the blood collection tube can be placed on the U-shaped clamp, thereby placing the blood collection tube inside the U-shaped clamp.

[0014] By adopting the above technical solution and by setting a spring, the clamping block can move into the spring groove after being squeezed until the blood collection tube is completely inserted into the U-shaped clamping plate. At this time, the spring resets and pushes the clamping block to move and lock the blood collection tube.
[0015] In a preferred embodiment, the front and back sides of the clamp are tilted at a certain angle.
[0016] By adopting the above technical solution and setting up clamping blocks, it is possible to facilitate the movement of the clamping blocks by squeezing the blood collection tube, and push the clamping blocks into the spring groove.
[0017] In a preferred embodiment, a railing is fixedly connected to the back of the clamp, and the number of railings is several.
[0018] By adopting the above technical solution and setting up several railings, the animal's sides can be protected.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0020] 1. In this application, the animal body is first driven into the clamping plates, then the motor is turned on. The motor drives the bidirectional threaded screw to rotate. The rotation of the bidirectional threaded screw drives the moving block to move using the threaded cylinder. The movement of the moving block drives the horizontal plate to move. The movement of the horizontal plate drives the clamping plate to move. The movement of the clamping plate then drives the pad plate to move and clamp the animal body on both sides. Then, the blood collection tube is pulled. At this time, the clamping block moves into the spring groove, and the blood collection tube is unfixed. Blood is then collected from the animal body, which solves the problem of difficulty in blood collection to a certain extent. Attached Figure Description

The inner wall of the U-shaped clamp 9 is equipped with a blood collection tube 8, and the inner wall of the blood collection tube 8 is equipped with a push rod 12. First, the animal body is driven into the clamp 4, then the motor 7 is turned on. The motor 7 drives the bidirectional threaded screw 16 to rotate. The rotation of the bidirectional threaded screw 16 drives the moving block 14 to move through the threaded cylinder 15. The movement of the moving block 14 drives the horizontal plate 3 to move. The movement of the horizontal plate 3 drives the clamp 4 to move. The movement of the clamp 4 then drives the pad 6 to move and clamp the animal body on both sides. Then, the blood collection tube 8 is pulled. At this time, the clamping block 10 moves into the spring groove 18, and the blood collection tube 8 is released from fixation. Then, blood is collected from the animal body, which solves the problem of difficulty in blood collection to a certain extent.
[0030] Reference Figure 1-2 The pad 6 is made of rubber. By setting the material of the pad 6 to rubber, the pad 6 can protect the animal body when the clamp 4 is clamping and restricting its movement, and prevent the clamp 4 from scratching the animal's skin.
