Therefore, these devices are widely used in animal experiments.

[0003] A search revealed that patent CN221511909U discloses a blood collection and positioning device for animal experiments; however, this device has the following shortcomings in use:

[0004] While the clamps can hold an animal by its neck, the clamping pressure cannot be monitored during the clamping process, which can easily cause discomfort or injury when securing the animal. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, which, although they can clamp an animal's neck with clamping blocks, cannot detect the clamping pressure during the clamping process, which can easily cause discomfort or injury when fixing the animal. Therefore, this invention proposes a blood collection positioning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A blood collection positioning device includes a base, a frame welded to the top of the base, the frame being U-shaped, and movable grooves formed on both inner walls of the frame. The inner walls of the two movable grooves are slidably connected to the same frame. A second concave plate is fixedly installed on one inner wall of the frame. The top and bottom inner walls of the frame are slidably connected to the same first concave plate. Both the first and second concave plates are concave. Clamping blocks for gripping the neck of an animal are placed inside both the first and second concave plates.

[0008] A clamping mechanism is installed on the frame to drive the first concave plate to move and clamp the animal's neck;

[0009] An adjustment mechanism, mounted on the frame, is used to adjust the height of the clamping blocks.

[0010] The testing mechanism is located inside the first concave plate and is used to test the clamping force.

[0011] In a possible design, the clamping mechanism comprises an electric push rod for driving the first concave plate to move, a fixed portion of the electric push rod is fixedly connected with an inner wall of one side of the frame body, and an extension portion of the electric push rod is fixedly connected with one side of the first concave plate.

[0012] In a possible design, the adjusting mechanism comprises a motor, a threaded rod and a moving block, a recess is formed in an inner wall of one side of the moving groove, the bottom of the motor is fixedly connected with the top of the frame body, the top end and the bottom end of the threaded rod are rotationally connected with the bottom inner wall and the top inner wall of the recess respectively, the output end of the motor penetrates through the top of the frame body and is fixedly connected with the top end of the threaded rod, one side of the moving block is slidably connected with one side of the inner wall of the recess, a threaded hole is formed in the moving block, the threaded rod is threadedly connected with the threaded hole of the moving block, and one side of the moving block is fixedly connected with one side of the frame body.

[0013] In a possible design, the detecting mechanism comprises a pressure sensor for detecting pressure and a pressure display for displaying a pressure value, one side of the pressure sensor is fixedly connected with an inner wall of one side of the first concave plate, one side of the first concave plate is provided with a through hole for facilitating the connection of a connecting line, one side of the pressure display is fixedly connected with one side of the frame body, and the pressure sensor is electrically connected with the pressure display.

[0014] In a possible design, the clamping block is made of rubber.

[0015] In a possible design, the top inner wall and the bottom inner wall of the frame body are both provided with a sliding groove for reducing friction generated by the movement of the first concave plate, and the top and the bottom of the first concave plate are both fixedly provided with a sliding block, one side of the sliding block is slidably connected with the inner wall of the sliding groove.

[0016] In the application, before use, the electric push rod and the motor are controlled by an external controller, a PLC controller can be used, then an external power supply is connected, the animal is pulled to the base, the height of the two clamping blocks is adjusted according to the position of the neck of the animal, the motor is started, and the output end of the motor drives the threaded rod to rotate. Since the moving block is in threaded connection with the threaded rod, the moving block will move along the axial direction of the threaded rod, and the movement of the moving block drives the frame body to slide up and down in the moving groove, so that the height of the clamping block is adjusted. When the height of the clamping block is adjusted to the position, the neck of the animal is stretched into the two clamping blocks, the electric push rod is started, and the telescopic part of the electric push rod starts to extend and retract, pushes the first concave plate to move towards the second concave plate, and the clamping blocks in the first concave plate and the second concave plate gradually approach and clamp the neck of the animal, so that the animal is positioned, and personnel can conveniently take blood from the animal. The clamping force of the clamping block on the neck of the animal is monitored in real time through the pressure sensor, and pressure data is transmitted to the pressure display. The operator can judge whether the clamping force is moderate by observing the numerical value on the pressure display, so as to avoid unnecessary harm to the animal. When the animal needs to be released in an emergency, the telescopic rod is retracted by controlling the electric push rod. Through the motor and the electric push rod, manual adjustment of the clamping block and the height is not needed, the labor intensity and operation time of the experimental personnel are effectively reduced, and the experimental efficiency is improved. Since the clamping block is placed in the first concave plate and the second concave plate, different clamping blocks can be replaced, different types and sizes of animals can be adapted, and the device can also be used in other experimental scenes requiring animal fixation, such as injection and measurement. The device can be used in animal experiments in the fields of biomedicine, veterinary medicine and pharmacology, improves the experimental efficiency and data accuracy, and is used as a teaching tool in medical colleges and scientific research institutions to help students better master animal experiment skills. The device can be repeatedly used, the consumption of experimental consumables is reduced, and the experimental cost is reduced. At the same time, due to the improvement of operation precision, the experimental failure rate and the animal mortality rate are reduced, and the experimental cost is further reduced. Through the improvement of the experimental efficiency and the data accuracy, the device helps researchers to obtain research results faster, thereby increasing the conversion rate and commercial value of research results.
