[0023] The blood testing separation and sampling device of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] This embodiment discloses a blood testing separation and sampling device. The design of the liquid aspiration component 2 allows blood to be drawn into the sampling tube 1. (Refer to...) Figures 1-6 The device mainly includes a sampling tube 1, inside which is a liquid aspiration component 2 for drawing blood. A moving rod 3 is slidably connected to the middle of the liquid aspiration component 2. A sealing head 6 for sealing the lower end of the sampling tube 1 is fixedly connected to the lower end of the moving rod 3. A mounting plate 4 is fixedly connected to the upper end of the moving rod 3. Lifting components 5 for lifting the mounting plate 4 are symmetrically fixedly connected to both sides of the upper end of the sampling tube 1. Through the coordinated design of the moving rod 3, mounting plate 4, lifting components 5 and sealing head 6, blood layers of different heights can be sampled, improving the practicality of the device. It can also simultaneously complete the tasks of sampling and preliminary storage, reducing the operation steps and time during blood transfer, thereby improving the overall work efficiency.

[0026] In order to collect blood samples. In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The aspiration assembly 2 includes a piston 201, a mounting block 202, and a pull rod 203. The piston 201 is slidably connected to the inner wall of the sampling tube 1. The mounting block 202 is fixedly connected to the middle of the upper end of the piston 201. The pull rod 203 is threadedly connected to both sides of the upper end of the mounting block 202 through threaded holes. In actual use, the mounting block 202 and the piston 201 are moved by the pull rod 203, thereby drawing blood into the sampling tube 1 to sample the blood. The pull rod 203 is threadedly connected to the mounting block 202, so the pull rod 203 can be disassembled, effectively preventing the blood in the sampling tube 1 from being squeezed out due to external force.

[0027] In order to move the sealing head 6 up and down. In this embodiment, refer to Figure 3 and Figure 4 The lower end of the moving rod 3 passes through the mounting block 202 and the piston 201 from top to bottom and is fixedly connected to the sealing head 6. The sealing head 6 can be moved up and down by the moving rod 3, which facilitates the control of the opening and closing of the lower end of the sampling tube 1.

[0028] To ensure the airtightness of piston 201, in this embodiment, refer to... Figure 3 and Figure 4 A sealing ring 7 is installed at the contact point between the lower end of the piston 201 and the moving rod 3. The sealing ring 7 can effectively prevent the airtightness of the piston 201 from being affected by the moving rod 3.

[0029] To facilitate the sealing of the lower end of the sampling tube 1 by the sealing head 6, in this embodiment, referring to... Figure 1 , Figure 5 and Figure 6 The lifting assembly 5 includes a mounting cylinder 501, a strong spring 502, and a T-shaped rod 503. The mounting cylinder 501 is fixedly connected to the upper end of the sampling tube 1. The lower end of the mounting cylinder 501 is fixedly connected to the strong spring 502, and the upper end of the strong spring 502 is fixedly connected to the T-shaped rod 503. The upper end of the T-shaped rod 503 is fixedly connected to the lower end of the mounting plate 4. When the mounting plate 4 is no longer pressed, the T-shaped rod 503 moves upward under the elastic force of the strong spring 502, thereby resetting the mounting plate 4, the moving rod 3, and the sealing head 6, which facilitates the sealing of the lower end of the sampling tube 1, making it convenient and quick.

[0030] To prevent the lower end of the T-shaped rod 503 from sliding out of the mounting sleeve 501, in this embodiment, refer to... Figure 6 The upper end of the mounting cylinder 501 is equipped with a retaining ring 504 to prevent the lower end of the T-shaped rod 503 from sliding out. By setting the retaining ring 504, the lower end of the T-shaped rod 503 can be blocked, thereby effectively preventing the lower end of the T-shaped rod 503 from sliding out of the mounting cylinder 501.

[0031] To achieve a better sealing effect at the lower end of sampling tube 1, in this embodiment, refer to... Figure 1 , Figure 3 and Figure 4 The plugging head 6 is a concentric reducing head and is adapted to the lower end of the sampling tube 1. The ingenious design of the plugging head 6 as a concentric reducing head not only facilitates the up and down movement of the plugging head 6, but also enables effective plugging, resulting in a better plugging effect.

[0032] To facilitate the removal of the sampled pull rod 203 from the mounting block 202, in this embodiment, refer to... Figure 1 , Figure 2 , Figure 3 and Figure 5 The upper diameter of the sampling tube 1 is larger than the middle diameter, which makes it easier for staff to turn the pull rod 203 and thus make it easier to remove the pull rod 203.

[0033] The working principle of this blood testing separation and sampling device is as follows: When blood needs to be sampled, the operator places the lower end of the sampling tube 1 in the blood to be sampled and manually presses down the mounting plate 4, causing the moving rod 3 and the sealing head 6 to move downwards until the sealing head 6 no longer blocks the lower end of the sampling tube 1. At this time, the pulling rod 203 is pulled to move the mounting block 202 and the piston 201 upwards, thereby drawing the blood to be sampled into the sampling tube 1. After sampling is completed, the mounting plate 4 is no longer pressed. Under the elastic force of the strong spring 502, the T-shaped rod 503 moves upwards, causing the mounting plate 4 to move upwards, thereby resetting the moving rod 3 and the sealing head 6, so that the sealing head 6 blocks the lower end of the sampling tube 1. This device can not only sample blood at different heights, but also pre-store the blood, reducing the operation steps and time in the blood transfer process, thereby improving the overall work efficiency.

[0034] During the initial blood storage process, turning the pull rod 203 allows it to be removed from the mounting block 202, effectively preventing the blood in the sampling tube 1 from being squeezed out due to external force.
