Furthermore, the lower deflection seat 709 and the upper deflection seat 711 cooperate with each other, so that the lower rotating block 710 and the upper rotating block 712 can rotate accordingly according to the orientation and flipping requirements, which provides great convenience for adjusting the angle and orientation of the monitoring display screen 713.

The top-view camera 718 can capture the internal situation of the centrifuge 1 from above, and can obtain the situation of the centrifugation process at any time. It works in conjunction with the high-speed capture camera 705 to capture information from multiple directions, thereby improving the accuracy of information acquisition. The plasma preparation cylinder 5 includes an outer collection cylinder 501, an outer piston extractor 502, an inner collection cylinder 503, an inner piston extractor 504, and a sealing sleeve 505; An outer piston extractor 502 is movably installed inside the outer collection cylinder 501. An inner collection cylinder 503 is embedded in the middle of the outer piston extractor 502. An inner piston extractor 504 is movably installed inside the inner collection cylinder 503. A sealing sleeve 505 is installed to cover the bottom of the outer collection cylinder 501. Pistons are connected to the bottom ends of the outer piston extractor 502 and the inner piston extractor 504. The two pistons are tightly fitted to the inner walls of the outer collection cylinder 501 and the inner collection cylinder 503, respectively. Threads are provided on the outer wall of the inner collection cylinder 503 and the inner wall of the outer piston extractor 502. The inner collection cylinder 503 and the outer piston extractor 502 are connected by threads. One end of centrifuge 1 is equipped with an ambient temperature control mechanism 8; The ambient temperature control mechanism 8 includes an air inlet pipe 801, an air outlet pipe 802, an axial flow fan 803, a metal adsorption frame 804, a magnetic sealing block 805, a heating box 806, an electric heating rod assembly 807, a start controller 808, an air inlet strip hole 809, a sealing plate 810, and a temperature sensor 811. An air inlet pipe 801 is embedded at one end of the centrifuge 1, and an air outlet pipe 802 is embedded at the middle end of the centrifuge 1 away from the air inlet pipe 801. An axial flow fan 803 is installed on the surface of the centrifuge 1 at a position corresponding to the air outlet pipe 802. A metal adsorption frame 804 is fixedly installed on the edge of the surface of the axial flow fan 803. A magnetic sealing block 805 is attached to the surface of the metal adsorption frame 804. The air inlet of the axial flow fan 803 is connected to the end of the air outlet pipe 802. A magnet is embedded in the inside of the edge of the magnetic sealing block 805. The magnetic sealing block 805 and the axial flow fan 803 are magnetically attracted and connected by the magnet and the metal adsorption frame 804. A heating chamber 806 is installed on the outer wall of centrifuge 1 at a position corresponding to the air inlet pipe 801. Electric heating rods 807 are equidistantly installed inside the heating chamber 806. A starter controller 808 is equidistantly installed at one end of the heating chamber 806. An air inlet hole 809 is provided at the bottom of the heating chamber 806. A sealing plate 810 is movably embedded in the bottom of the heating chamber 806. A temperature sensor 811 is installed at one end inside the centrifuge 1. The heating chamber 806 is connected to one end of the air inlet pipe 801. The starter controller 808 is connected to the power cord of the electric heating rods 807. A sliding groove is provided at the bottom of the heating chamber 806. The two sides of the sealing plate 810 are movably embedded in the sliding groove. The axial flow fan 803 and the air inlet pipe 801 work together to make the gas inside the centrifuge 1 flow. The gas inside the heating box 806 replaces the air inside the centrifuge 1. The continuous flow of gas will have a certain cooling effect. The electric heating rod group 807 heats the air inside the heating box 806. The heated air replaces the air inside the centrifuge 1, which can effectively increase the internal temperature of the centrifuge 1. It realizes the heating and cooling operation of the internal environment of the centrifuge 1, and provides a suitable temperature environment for centrifugation preparation. Simultaneously, the controller 808 can precisely control the start-up of multiple sets of electric heating rods 807. According to the temperature requirements, the corresponding number of electric heating rods 807 can be selected to work. The control operation is simple. Furthermore, the magnetic sealing block 805 and the sealing plate 810 can be used to seal and block after the temperature regulation is completed, preventing the gas inside the centrifuge 1 from flowing out and causing temperature changes.
[0020] The working principle and usage process of this invention are as follows: First, the staff inserts an external blood collection needle into the arm of the person collecting blood. One end of the needle is connected to the bottom of the outer collection cylinder 501 through a tube. The inner piston extractor 504 is used to draw blood upwards, which can directly draw blood into the inner collection cylinder 503. After a certain amount is drawn, the outer piston extractor 502 is pulled upwards to draw blood, which will then enter the outer collection cylinder 501 for storage. The needle is removed, and the bottom of the outer collection cylinder 501 is sealed with a sealing sleeve 505. The staff places the plasma preparation cylinder 5 as a whole inside a storage cylinder 4. A stable counterweight 6 is placed inside the storage cylinder 4 at the opposite position to achieve a balanced state. The shooting notch 707 exposes part of the plasma preparation cylinder 5. The flip cover 2 is closed downwards, and the inner wall of the positioning groove 716 is tightly attached to the edge of the sealing ring 715, so that the top of the centrifuge 1 is sealed. The monitoring display screen 713 is flipped outwards, so that it rotates around the lower deflection seat 709 and moves out of the storage and protection frame 708. Then it is rotated around the upper deflection seat 711 to adjust its orientation and deflection angle. The temperature sensor 811 monitors the ambient temperature inside the centrifuge 1. A suitable temperature environment is needed for separation preparation. The start controller 808 controls the start of the electric heating rod assembly 807, selecting the number of rods to start based on temperature requirements. More rods result in longer heating time and higher temperatures, while fewer rods result in lower heating temperatures. The sealing plate 810 is then pulled outwards, and the magnetic sealing block 805 is removed from the surface of the axial flow fan 803. The axial flow fan 803 starts, generating airflow to circulate the air inside the centrifuge 1. The air is discharged outward. Affected by the airflow, the air heated by the electric heating rod group 807 inside the heating box 806 enters the centrifuge 1, replacing the air inside the centrifuge 1 and changing the ambient temperature inside the centrifuge 1. After the temperature is maintained at a certain temperature, the axial flow fan 803 and the electric heating rod group 807 are turned off. The magnetic sealing block 805 is attached to the surface of the axial flow fan 803 and is fixed to the metal adsorption frame 804. The sealing plate 810 blocks the air inlet 809 at the bottom of the heating box 806, so that the inside of the centrifuge 1 remains sealed. The centrifuge 1 utilizes a continuously rotating disc 3 inside the centrifuge at high speed to drive the plasma preparation cylinder 5 to rotate, achieving centrifugal preparation. The centrifugation process is captured by a top-view camera 718, allowing for timely adjustments to the rotation speed. After centrifugation, platelets-rich cells float to the inner collection cylinder 503, while red blood cells and white blood cells sink to the outer collection cylinder 501. Platelets are lighter in color, while red blood cells are darker, creating a color difference during centrifugation. A timer controller 714 controls the high-speed capture camera 705 to capture images at regular intervals, transmitting the captured information to a monitoring display screen 713. Staff analyze the centrifugation preparation status based on the color changes captured by the high-speed capture camera 705, accurately grasping centrifugation information and reducing human error.
