Technical Field

[0002] Serum sample is the liquid part extracted from blood, usually obtained by centrifugation after blood coagulation. Serum is mainly composed of water, electrolytes, proteins (such as immunoglobulins and albumin), hormones and metabolites, and has the function of transporting nutrients, waste and hormones.

[0003] Serum samples are stored frozen to extend their shelf life and maintain their biological activity. Low temperatures inhibit microbial growth and slow biochemical reactions, preventing degradation or deterioration of sample components. Frozen storage also helps preserve the integrity of proteins and other biomolecules in serum, improving the accuracy and reliability of subsequent analyses.

[0026] Specifically, when it is necessary to store the sample in the test tube 15, the push plate 6 is pulled to squeeze the spring 8, driving the fixed rod 9 to move forward, driving the transmission plate 10 to move forward, and under the action of the fixed rod 11, the slide plate 12 and the clamping plate 14 are driven to move to the left, and the test tube 15 is placed in the horizontal position of the clamping plate 14. The push plate 6 is released and, under the elastic force of the spring 8, the slide plate 12 and the clamping plate 14 are driven to move to the right to clamp and fix the test tube 15, thereby reducing the possibility of damage to the sample. The spring 8 limits the range of the push plate 6, and the slide rail 13 limits the offset of the slide plate 12. When storing the test tube 15, the freezing environment generated by the refrigeration plate 3 achieves the effect of improving the sample storage stability. When the device needs to be moved, the handle 2 facilitates the movement of the box 1.

[0027] Reference Figure 3 , the front outer wall of the slide rod 7 is fixedly connected to the rear outer wall of the fixed plate 5, the front outer wall of the spring 1 8 is fixedly connected to the rear outer wall of the fixed plate 5, and the lower surface of the slide rail 13 is fixedly connected to the upper surface of the fixed plate 5;

[0028] Specifically, the outer wall of the slide bar 7 limits the sliding of the push plate 6 to achieve the effect of limiting the offset, and the spring 1 8 limits the range of the push plate 6 to achieve the effect of limiting the range.
