[0003] At present, the temperature control is generally carried out by using cold storage agent (ice block or ice bag), but the placement and fixing mode of the cold storage agent in many heat preservation boxes in the prior art is not scientific enough, the cold storage agent is placed randomly in the heat preservation box, and the influence of the distribution of the cold storage agent on the temperature in the box is not fully considered. This leads to the fact that a uniform low-temperature environment cannot be formed in the heat preservation box, the temperature in some areas is too high or too low, and the stability and activity of the samples are seriously affected. Moreover, the cold storage agent is not fixed well, and is easy to shake during transportation, which not only causes temperature fluctuation, but also greatly increases the risk of collision with the samples, causing damage to the samples.

[0027] A medical testing biological sample insulator, such as Figures 1-8 As shown, the device includes a box body 2, with an opening at the top and a hollow chamber 18 inside. A lid 3 is connected to the opening. The box body 2 includes two sets of symmetrically arranged long side plates 4 and short side plates 5, which are connected in sequence. Two protruding prisms 6 are symmetrically arranged on the inner wall of the long side plate 4. A first ice block 14 is inserted vertically between the two prisms 6 on the same long side plate 4. A second ice block 15 is inserted vertically between the short side plate 5 and its two adjacent prisms 6. A gap 17 is left between the top of the prisms 6 and the top opening of the box body 2. Two third ice blocks 16 are placed side by side in the gap 17.
[0028] The opposite side of the two prisms 6 on the long side plate 4 is provided with an inclined surface 7, which is inclined from the cavity 18 to the long side plate 4. The two inclined surfaces 7 and the inner wall of the long side plate 4 form an outer narrow and inner wide clamping groove 8, so that the first ice block 14 is fixed in the clamping groove 8 after being inserted from the top of the clamping groove 8 and is not easy to move. More preferably, the corners of the prisms 6 are smoothly transitioned.
[0029] The cross section of the clamping groove 8 is an isosceles trapezoid, as shown in Figure 8 The length of the long side of the trapezoid is the distance d1 between the innermost ends of the two inclined surfaces 7 on the same long side plate 4, the length of the short side of the trapezoid is the distance d2 between the outermost ends of the two inclined surfaces 7 on the same long side plate 4, the length of the height of the trapezoid is the distance d3 between the outermost end and the innermost end of the same inclined surface 7, the length L1 of the first ice block 14 is greater than the length of the short side of the trapezoid and less than the length of the long side (d1 < L1 < d2), and the width L2 of the first ice block 14 is less than the length of the height of the trapezoid (L2 < d3).
[0030] The length of the second ice block 15 is the same as the length of the short side plate 5, and the width of the second ice block 15 is the distance between the short side plate 5 and the adjacent prism 6. The height of the first ice block 14 and the second ice block 15 is the same as the height of the prism 6, so that the first ice block 14 and the second ice block 15 are flush with the top surface of the prism 6, and the third ice block 16 is stably and horizontally placed above the prism 6.
[0031] The length of the third ice block 16 is the same as the length of the short side plate 5, the width of the third ice block 16 is half the length of the long side plate 4, and the thickness of the third ice block 16 is not greater than the height of the interval. The third ice block 16 is placed in the interval and does not affect the opening and closing of the box cover 3.
[0032] As shown in Figure 4 The box cover 3 is provided with a placement groove 9 at the top, and a temperature recorder (not shown in the figure) is fixedly connected in the placement groove 9. An opening 10 is formed in the bottom of the placement groove 9, and the temperature probe of the temperature recorder extends into the box body 2 to measure the temperature. By fixing the temperature recorder in the placement groove 9 at the top of the box cover 3, the temperature probe and the wire of the temperature recorder extend from the opening 10 to avoid the cavity inside the box body, which is convenient for the staff to check the temperature in the insulation box 1 in real time during transportation, and does not need to open the box cover frequently, avoiding the pollution of external microorganisms, dust and other pollutants into the box, and causing pollution to the sample. The temperature recorder adopts the product in the prior art, such as Jingchuang RCW-260, and its structure and use method are not repeated here.
[0033] As shown in Figure 2 and Figure 5As shown, the edge of the top opening of the box body 2 is provided with a double-layer sealing groove 12, and the bottom edge of the box cover 3 is provided with a double-layer sealing ring 13 matched with the sealing groove 12. By providing a double-layer sealing structure, the sealing performance of the heat preservation box 1 is ensured, air exchange is isolated, and the temperature control efficiency is improved.
[0034] The top opening edge of the box body 2 is provided with a buckle 11 at the diagonal of both sides, which facilitates the opening and closing of the box cover 3. In other embodiments, corresponding buckles can also be provided between the box cover 3 and the box body 2 to enhance the fixation and sealing performance of the box cover 3.
[0035] Specifically, the box body 2 is made of EPP (expanded polypropylene) material by foaming process, which has the characteristics of light weight, firm structure, excellent heat preservation performance, etc.
[0036] Preferably, the application also includes a heat shield box (not shown in the figure) matched with the heat preservation box, which is matched in size with the heat preservation box 1. The heat shield box includes a non-woven fabric outer layer, an aluminum film pearl wool heat preservation layer and an aluminum foil inner layer. The heat shield box is opened and closed by means of zipper, magic tape or buckle, etc., which plays a sealing and fixing role for the heat preservation box. The heat shield box is provided with a transparent window at the position corresponding to the placement groove 9 on the top, which facilitates the staff to check the temperature in the heat preservation box 1. The heat shield box is provided with a handle or a shoulder strap outside, which facilitates carrying.
[0037] The first, second and third ice blocks 14, 15 and 16 are all placed in an environment below-15℃ for freezing for more than 24 hours to make the cold storage agent solid, and then placed in a room temperature environment (15-25℃) for 30-60 minutes to make the cold storage agent produce a small amount of liquid. The two first ice blocks 14 are respectively inserted between the prisms 6 of the two long side side plates 4, and the two second ice blocks 15 are respectively inserted between the prisms 6 adjacent to the two short side side plates 5. After the biological sample is placed in the chamber 18 of the box body 2, the two third ice blocks 16 are placed side by side in the space between the top of the prism 6 and the opening of the box body 2, and the box cover 3 is sealingly connected to the top opening of the box body 2. Thus, the ice blocks are arranged around the biological sample to form a refrigeration environment, and the position of the ice blocks is fixed and not easy to move.
