Description

Technical Field

[0001] This utility model belongs to the field of biomedical testing technology, and in particular relates to a magnetic bead separator for medical test samples. Background Technology

[0002] The medical testing sample magnetic bead separation rack is a key device in the medical testing field that uses a magnetic field to achieve rapid separation of magnetic beads and samples. It is widely used in nucleic acid extraction, protein purification, and cell sorting experiments. Its core principle is to use specific groups modified on the surface of the magnetic beads to bind with the target substance. Then, the magnetic field generated by the device adsorbs the magnetic beads and the bound target substance to the container wall, thereby achieving separation from other components in the sample solution. This provides high-purity target samples for subsequent testing and is an important tool for improving the efficiency and accuracy of medical testing.

[0003] Early magnetic bead separation devices were simple in structure, mostly consisting of a single permanent magnet and a fixed tray. The tray could only accommodate test tubes of specific sizes and lacked an effective fixing structure. During operation and transfer, the test tubes were prone to shaking or even tipping over, leading to sample spillage and unstable magnetic bead separation results. To solve these problems, existing magnetic bead separation racks have adopted an adjustable slot design, using elastic buckles or silicone pads to fix test tubes of different sizes, and optimizing the layout of magnetic components to improve magnetic field uniformity. During operation, these fixing structures can firmly lock the test tubes, preventing shaking from affecting the separation accuracy during operation. However, during transportation, because the magnetic components, tray, and base of the device are mostly rigidly connected, and the buffer space between the test tube and the slot is limited, when subjected to bumps or impacts, the test tube will collide hard with the edge of the slot, resulting in breakage, sample loss, and experimental delays. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic bead separator for medical test samples, which aims to solve the technical problem in the prior art where, during transportation, test tubes will collide hard with the edge of the slot when subjected to bumps or impacts, resulting in breakage, sample loss, and experimental delays.

[0041] Reference Figure 1 , Figure 2 and Figure 3 Handles 2 6 are fixedly connected to the front and rear sides of the outer wall of the hollow block 1. Handles 2 6 facilitate the carrying of the device from the front and rear directions to improve portability. Observation windows 7 are fixedly connected to the left and right ends of the front side of the hollow block 1.

An alarm 9 is fixedly connected to the rear end of sensor 8. The alarm 9 can sound an alarm when sensor 8 detects an abnormality to remind the operator to deal with it in time.

[0042] Specifically, the hollow block 1 provides the mounting base for the second handle 6, the observation window 7, the sensor 8, and the alarm 9. The second handle 6, fixed to the front and rear sides of the outer wall of the hollow block 1, facilitates the transport of the device from the front and rear directions, thereby improving portability.

The alarm 9, fixed to the rear end of the sensor 8, works in conjunction with the sensor 8 to issue an alarm when the sensor 8 detects an abnormality, so as to remind the operator to deal with it in time. The components work together to realize the functions of convenient transport of the device, observation of internal status, and monitoring and alarm of internal environmental anomalies, ensuring the convenience and safety of the device during use.

[0043] Working principle: When the instrument needs to be transported, the top cover 202 is closed. During the closing process of the top cover 202, the isolation plate 203 at the bottom will be precisely embedded inside the sample box 201. The reserved holes on the isolation plate 203 correspond one-to-one with the test tubes, so that each test tube is independently in an isolated space. When encountering external impact during transportation, the spring 206 converts the hard impact into elastic potential energy, which greatly reduces the impact force transmitted to the test tubes. The isolation plate 203 floats slightly with the top cover 202, and forms a dynamic buffer with the extension and contraction of the spring 206 to avoid rigid compression between the isolation plate 203 and the top of the test tube. In addition, the rubber block 207 covers the outer wall and bottom of the sample box 201, which can further absorb the external impact force. When the instrument is hit from the side or bottom, the rubber block 207 wraps the sample box 201 through the elastic deformation of its own material, reducing its direct collision with the external structure, and at the same time weakening the vibration energy transmitted to the internal test tubes.

[0044] Furthermore, when the instrument needs to be closed, the cover plate 303 flips towards the top of the hollow block 1 under the rotation of the damping hinge 301. The damping hinge 301 provides uniform resistance, allowing the cover plate 303 to be suspended at any angle, facilitating precise alignment with the top edge of the hollow block 1. The cover plate 303 and the two magnets 304 on the hollow block 1 attract each other due to magnetic force, forming a tight lock to prevent the cover plate 303 from loosening during movement. In the closed state, the corrugated plate 302 acts as a rigid protective layer covering the top of the hollow block 1. External impact forces are evenly distributed through the cover plate 303, reducing collisions caused by shaking of internal components. At the same time, the compact structure of the hollow block 1 achieves volume compression. When it needs to be opened, the handle 305 is pulled, the damping hinge 301 releases the rotational resistance, and the cover plate 303 slowly flips open with the pulling force, avoiding component impact caused by sudden drop in gravity.

[0045] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
