[0025] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Reference Figures 1 to 5 As shown, a preferred embodiment of the present application of a blood preservation box includes a box body 1, a box lid 2, a test tube rack 3, and a shock-absorbing support structure 4. The box lid 2 is connected to the box body 1 to form a receiving cavity 10. The box lid 2 can be rotated open. The two opposite sides of the receiving cavity 10 are provided with shock-absorbing support structures 4. The test tube rack 3 is disposed in the receiving cavity 10 and is mounted on the shock-absorbing support structure 4. The test tube rack 3 is used to load test tubes containing blood.

[0027] Specifically, the blood preservation box with the above structure transports blood. The test tube rack 3 loads test tubes containing blood. The test tube rack 3 is located in the receiving cavity 10 and mounted on the shock-absorbing support structure 4. Based on this, during the transportation of blood, the vibration of the test tube rack 3 can be reduced due to the setting of the shock-absorbing support structure 4, thereby effectively reducing the occurrence of hemolysis.

[0028] In this embodiment, the shock-absorbing support structure 4 includes a connecting plate 41, a mounting column 42, a spring 43, and a floating seat 44. The connecting plate 41 is connected to the side surface of the receiving cavity 10, and the thickness direction of the connecting plate 41 extends vertically. The mounting column 42 is connected to the top surface of the connecting plate 41, and the length direction of the mounting column 42 extends vertically. The top surface of the mounting column 42 is provided with a mounting hole 4201, and the spring 43 is inserted into the mounting hole 4201. The floating seat 44 is connected to the end of the spring 43 away from the connecting plate 41 along its length direction. The test tube... The frame 3 is mounted on the top surface of the floating seat 44. Specifically, the spring 43, as the core shock-absorbing element, can absorb and buffer vibration energy through elastic deformation before the vibration is transmitted to the test tube frame 3. When external vibration occurs, the spring 43 is compressed or stretched, converting the kinetic energy of the vibration into its own elastic potential energy, thus preventing the vibration from directly acting on the test tube frame 3 mounted on the floating seat 44. This effectively protects the blood sample in the test tube, reduces hemolysis caused by vibration, ensures the quality of the blood sample, and provides reliable protection for subsequent medical operations such as testing.

[0029] In addition, the spring 43 is installed by mounting post 42, which has a simple structure, is easy to install, and has high connection stability.

[0030] Furthermore, the floating seat 44 has a mounting groove 4401 on the side facing the connecting plate 41. The spring 43 is connected to the bottom surface of the mounting groove 4401, and the mounting post 42 is inserted into the mounting groove 4401. At this time, the mounting post 42 can play a limiting role, which can constrain the position of the floating seat 44 in the horizontal direction and prevent it from lateral shaking or displacement due to transportation vibration, thus ensuring high reliability.

[0031] Preferably, the outer peripheral surface of the mounting column 42 contacts the side surface of the mounting groove 4401. In this case, the floating seat 44 can only move in the vertical direction, which can reduce the horizontal shaking of the test tube rack 3 and help reduce the occurrence of hemolysis.

[0032] It should be noted that the number of shock-absorbing components formed by the mounting column 42 and the spring 43 can be multiple, which can improve the shock absorption capacity. This application does not limit this.

[0033] Furthermore, the shock-absorbing support structure 4 also includes a first shock-absorbing pad 45, which is connected to the side of the cavity 10 and positioned above the connecting plate 41. The first shock-absorbing pad 45 abuts against the test tube rack 3. Specifically, the first shock-absorbing pad 45 is made of a highly elastic, high-damping material, such as silicone, rubber, or memory foam. It absorbs vibration through elastic deformation, further reducing the vibration energy transmitted to the test tube rack 3, which helps to reduce the occurrence of hemolysis. Additionally, such as... Figure 2From a certain perspective, the first shock-absorbing pad 45 abuts against the test tube rack 3, and there is friction between the first shock-absorbing pad 45 and the test tube rack 3, which can prevent the test tube rack 3 from shaking back and forth and up and down.

[0034] The first shock-absorbing pad 45 can be connected to the side of the cavity 10 by adhesive bonding, which is simple in structure and easy to install.

[0035] In this embodiment, the test tube rack 3 includes a rack body 31 and connecting ears 32. The rack body 31 has multiple receiving holes 3101 for loading test tubes. Connecting ears 32 are connected to opposite sides of the rack body 31. The bottom surface of the connecting ears 32 is mounted on the floating seat 44. The side of the connecting ears 32 facing away from the rack body 31 abuts against the first shock-absorbing pad 45. This type of test tube rack 3 has a simple structure and can cooperate with the shock-absorbing support structure 4 to reduce the occurrence of hemolysis in blood samples. It should be noted that a silicone ring is connected to the hole wall of the receiving hole 3101. The test tube is inserted into the silicone ring and the silicone ring fixes the test tube to the rack body.

[0036] Furthermore, the blood preservation box also includes a second shock-absorbing pad 5, which is connected to the bottom surface of the receiving cavity 10. The test tube rack 3 is mounted on the top surface of the second shock-absorbing pad 5. Specifically, the second shock-absorbing pad 5 is made of a highly elastic and high-damping material, such as silicone, rubber, or memory foam. Similarly, the second shock-absorbing pad 5 also absorbs vibration through elastic deformation. The test tube rack 3 is mounted on the top surface of the second shock-absorbing pad 5, which can reduce the vibration energy transmitted to the test tube rack 3 and help reduce the occurrence of hemolysis.

[0037] In this embodiment, the blood preservation box also includes a heating element 6; the two opposite sides of the receiving cavity 10 are provided with receiving grooves 101, and the receiving grooves 101 are provided with heating elements 6. Specifically, based on the setting of the heating element 6, in practical applications, when the external ambient temperature is too low (such as during winter transportation or storage), the heating wire can help maintain the temperature inside the box, prevent the blood from freezing, and ensure the quality of the blood sample.

[0038] For example, the heating element 6 includes a housing and a heating wire disposed inside the housing, which is energized to generate heat.

[0039] Furthermore, the blood preservation box can also be equipped with a temperature sensor and a controller. The temperature sensor and controller are connected to the box body 1. The temperature sensor is used to monitor the temperature of the containing cavity 10. The heating wire is linked with the temperature sensor and controller. When the temperature inside the box is lower than the set threshold, heating is automatically started and stopped after the threshold is reached to avoid temperature overshoot. The controller can be a microcontroller or a PLC, which is the prior art and will not be described in detail in this application.

[0040] In practical applications, the placement of the heating wire, temperature sensor, controller, and related electrical connection wires is determined according to the specific application, which is a technology well known to those skilled in the art, and this application does not impose any restrictions on it.

[0041] Preferred, such as Figure 4 As shown, the cavity side of the receiving cavity 10 connected to the shock-absorbing support structure 4 is referred to as the first cavity side. The first cavity side is provided with a receiving groove 101, and the front and rear sides of the shock-absorbing support structure 4 are provided with receiving grooves 101. At this time, the front and rear sides of the shock-absorbing support structure 4 are provided with heating elements 6, which can ensure that the temperature of the receiving cavity 10 is uniform and is conducive to ensuring the quality of blood samples.

[0042] In this embodiment, the lid 2 is connected to the front side of the box body 1. With this structure, the test tube rack 3 is placed into the receiving cavity 10 from front to back, which is convenient for operation.

[0043] It should be noted that the front and rear sides of the shock-absorbing support structure 4 are based on the installation positions of the housing 1 and the cover 2. That is, the side of the housing 1 with the cover 2 is the front side, and the opposite side is the rear side.

[0044] Furthermore, the box body 1 is filled with a first insulation layer 7, and the box cover 2 is filled with a second insulation layer 8. The first insulation layer 7 and the second insulation layer 8 surround the receiving cavity 10. Specifically, the setting of the first insulation layer 7 and the second insulation layer 8 can ensure the temperature inside the receiving cavity 10 is stable, reduce heat loss, and help ensure the quality of blood samples.

[0045] For example, the first insulation layer 7 and the second insulation layer 8 are made of polyurethane.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
