[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of the present invention will now be described.

[0025] A blood sample collection and preservation device, such as Figure 1 As shown, a blood sample collection and preservation device includes a lower preservation box 1, an upper preservation box 2 on top of the lower preservation box 1, and blood collection tube grooves 3 on the top of both the upper and lower preservation boxes 1. A protective cover 8 is provided at one end of the top of the upper preservation box 2. Blood collection tubes 7 are provided inside the blood collection tube grooves 3. A secondary fixing frame 5 is fixed to one side of the blood collection tube 7 on the top of the upper preservation box 2, and a main fixing frame 4 is provided to the other side of the blood collection tube 7 on the top of the upper preservation box 2. A connecting rod 6 is fixedly connected to one side of the main fixing frame 4, and a movable rod 29 penetrating the protective cover 8 is fixed to one end of the connecting rod 6. The main fixing frame 4 and the secondary fixing frame 5 cooperate with each other, and both the main fixing frame 4 and the secondary fixing frame 5 are provided with grooves that cooperate with the blood collection tubes 7. The diameter of the blood collection tube groove 3 is larger than the diameter of the blood collection tube 7.

[0026] By directly cooperating with the main fixing frame 4 and the auxiliary fixing frame 5 set on both sides of the blood collection tube groove 3, the blood collection tube 7 can be fixed and released when the moving rod 29 with the connecting rod 6 is moved, making the blood collection tube 7 easy to pick up and put down.

[0027] Please refer to this carefully. Figure 2 and Figure 3 A ratchet 12 is provided on one side of the end of the moving rod 29. A pawl 13 that cooperates with the ratchet 12 is rotatably connected inside the protective cover 8. A lever 10 is fixed on one side of the pawl 13. A lever groove 9 that cooperates with the lever 10 is provided at the top of the protective cover 8.

[0028] The cooperation between the pawl 13 and the ratchet 12 ensures that the moving rod 29 cannot move to the side of the blood collection tube 7 due to the ratchet during transportation, thus preventing the main fixing frame 4 from leaving the blood collection tube 7 and improving the fixation effect of the sample during transportation.

[0029] Please refer to this carefully. Figure 1 , Figure 4 and Figure 5 The upper storage box 2 has fixed posts 16 on both sides, and the ends of the fixed posts 16 are rotatably connected to the first connecting rod 17. The other end of the first connecting rod 17 is fixedly connected to the telescopic rod 27. The lower storage box 1 has first sliding grooves 19 on both sides, and the sliding block 21 is slidably connected inside the first sliding groove 19. The end of the sliding block 21 is rotatably connected to the second connecting rod 18. The end of the second connecting rod 18 has a moving groove 11. One end of the moving groove 11 is fixedly connected to the first spring 28, which is fixedly connected to the telescopic rod 27. The moving groove 11 and the telescopic rod 27 cooperate with each other. The top and one side of the lower storage box 1 are provided with fixed grooves 15. The bottom and one side of the upper storage box 2 are provided with fixed blocks 14 that cooperate with the fixed grooves 15.

[0030] Through the above design, the upper storage box 2 can be moved upward, so that the fixing block 14 at the bottom of the upper storage box 2 leaves the fixing groove 15 at the top of the lower storage box 1. Then, the upper storage box 2 is moved to one side, causing the slider 21 to slide and causing the second connecting rod 18 and the telescopic rod 27 to move. When the upper storage box 2 moves to one side of the lower storage box 1, the upper storage box 2 is pushed to the lower storage box 1, so that the fixing block 14 on the side of the upper storage box 2 is installed into the fixing groove 15 on the side of the lower storage box 1, and the fixing is completed. At this time, the lower storage box 1 can also be used for sample storage.

[0031] Please refer to this carefully. Figure 4 and Figure 6 The slider 21 has a second groove 22 inside, and a second spring 25 is fixed to one end of the second groove 22. A slide rod 23 that passes through the slider 21 is slidably connected inside the second groove 22, and a lever 26 is fixed to one end of the slide rod 23. A fixing ring 24 connected to the other end of the second spring 25 is provided on the outside of the slide rod 23. Both ends of the first groove 19 are provided with slots 20 that cooperate with the slide rod 23.

[0032] The above design ensures that the slider 23 can only leave the slot 20 after the lever 26 is pulled, at which point the slider 21 can slide. That is, the slot 20 fixes the slider, preventing the upper storage box 2 from separating from the lower storage box 1.

[0033] Please refer to this carefully. Figure 1 The top of the upper storage box 2 is provided with a protective cover, and the protective cover is surrounded by a heat insulation component, which includes a compressor, a condenser, a dryer filter, a capillary tube, and an evaporator.

[0034] The design of the insulation components around the protective cover allows the blood sample to be kept at a temperature of 4°C.

[0035] The working principle of this invention is as follows: First, open the protective cover. Then, move the lever 10 to move the pawl 13 away from the ratchet 12. Next, push the moving rod 29 into the upper storage box 2 to disengage the main fixing frame 4 from the blood collection tube 7. Then, take out the blood collection tube 7 to store the blood sample. When the upper storage box 2 is full of blood sample, move the pawl 13 again to move it onto the ratchet 12. Then, pull the moving rod 29 outward to fix the main fixing frame 4 to the blood collection tube 7. Next, pull the lever 26 outward and slightly move the second connecting rod to disengage the sliding rod 23 from the slot 20. Then, move the upper storage box 2... The storage box 2 is lifted upwards, causing the first connecting rod 17 and the second connecting rod 18 to move. Then, the upper storage box 2 is moved to one side to the side of the lower storage box 1. Next, it moves to the lower storage box 1, locking the fixing block 14 into the fixing groove 15. Then, the push block 26 is pushed inwards again to fix the sliding rod 23 in the slot 20, thus completing the fixation of the upper storage box 2 and the lower storage box 1. The above actions are repeated to complete the storage of blood samples in the lower storage box 1. After the lower storage box 1 is full, the above process is repeated to move the upper storage box 2 to the top of the lower storage box 1 and cover it with the protective cover to complete the blood sample storage.
