A handle, a nameplate, a blood type label frame and the like are arranged outside the box body 1. The top of the box cover 2 and the bottom of the box body 1 are designed with a specified standard concave-convex rib to meet the storage stacking requirements. The box cover 2 and the box body 1 are engaged with a stepped surface, and a sealing groove is further arranged on the box cover 2, a sealing ring is embedded in the sealing groove, and a protruding part capable of being embedded in the sealing groove and pressing the sealing ring is arranged on the box body 1, thereby forming an airtight and waterproof sealing structure. The sealing rubber strip is made of silica gel material, which has moderate hardness, low water absorption and aging resistance, and realizes pressureless airtight sealing from the aspects of material and structural design.

[0033] The side wall, the bottom wall of the inner cavity of the box body 1 and the inner surface of the box cover 2 are provided with protruding ribs arranged at intervals, and channels for air flow are formed between the ribs.

[0034] A plurality of hollow blood storage baskets 3 are neatly arranged in the inner cavity of the box body 1, the blood storage baskets 3 can be made of steel wire mesh, and shock absorbing pads 31 are fixed on the side wall and the bottom wall of the blood storage baskets 3, preferably silica gel shock absorbing pads. The shock absorbing pad 31 at the bottom of the blood storage basket 3 is a cylindrical block, which is rotatably fixed on the blood storage basket 3. When jolting or sudden braking occurs, the blood storage basket 3 will preferentially displace, thereby avoiding impact between the blood bags and the blood storage basket 3. The arrangement of the shock absorbing pad 31 avoids hemolysis caused by vibration during blood transport, and has a certain shock absorbing effect, which can be used to ensure the blood transport task of the blood station under harsh road conditions and improve the blood emergency storage and transportation and protection capacity.

[0035] In a preferred embodiment, four blood baskets are used to fill one blood transport box, each blood storage basket 3 can accommodate 25 blood bags of 100ml, and the blood bags are stacked in two layers in the box to avoid mutual extrusion. When stored and used, the blood-filled baskets are sequentially placed in the box.

[0036] The box body 1 and the blood storage basket 3 are filled with cold storage ice blocks, the box body 1 is used for temperature insulation, the cold storage ice blocks are filled with phase change agent, and the temperature in the box is adjusted and controlled passively, so that the blood transport box can meet the temperature control requirements within a certain time. The side ice blocks 41 are filled between the blood storage basket 3 and the side wall of the box body 1, the upper ice blocks 42 are filled between the top of the blood storage basket 3 and the box cover 2, and the lower surface of the upper ice blocks 42 is fixed with a temperature insulation pad 43.

[0037] The blood transport box also comprises a temperature monitoring system, which comprises a temperature sensor arranged in the box body 1 and a controller electrically connected with the temperature sensor, the controller having a temperature recording module, an alarm module and a display panel arranged on the outer wall of the box body 1, when the temperature sensor detects that the temperature in the box is higher than the set value, the controller controls the alarm module to send an alarm signal, and stores the temperature value detected by the temperature sensor on the temperature recording module, so that the temperature record can be reviewed before blood transfusion, and the safety of blood transfusion is ensured.

[0038] In addition, in the temperature monitoring system, the selection of the battery also has a low-temperature adaptability requirement. We select a low-temperature-resistant lithium battery in accordance with GJB / Z 53.2-94 Military Battery Series Lithium Battery from the perspective of operational convenience. In order to meet the safety requirements in the cold region at-41℃ and facilitate use, we design the battery storage tank in the inner cavity, so that the internal minimum temperature is-20℃ when used in low temperature, thereby reducing the influence of-41℃ temperature on the performance of the battery.

[0039] The electromagnetic compatibility protection of the temperature monitoring system is relatively easy:

[0040] ①Spray a shielding film layer on the controller, and paste a shielding film on the display panel, without dead angles, which also plays a protective role;

The outer shell and the inner shell body of the blood transportation box are made of carbon fiber material, which can meet the performance needs in relatively complex service environments, realize the demand of greatly reducing the weight, and has good high and low temperature resistance.

[0049] In order to ensure the neatness of the storage of the blood storage baskets 3, the positioning piece 6 is arranged between the upper and lower blood storage baskets 3, the positioning piece 6 comprises an angular piece fixed to the top four corners of the lower blood storage basket 3, the angular piece protrudes upward from the lower blood storage basket 3, and the two blood storage baskets 3 stacked up and down are positioned by the angular piece, and the collision between the blood storage baskets 3 during shaking is also prevented.

[0050] In one preferred embodiment, each block of cold storage ice row 42 covers one blood storage basket 3, and when blood is taken, one side of the ice row 42 is opened, and the ice row 42 can be taken as a whole or by zero according to the needs, which is flexible and convenient.

[0051] The blood transportation box has high altitude adaptability and can normally work in an area with an altitude of not less than 4500 m. The short side of the blood transportation box is provided with an air pressure adjusting valve, so that the packaging box meets the needs of high altitude work. The air guide pipe 7 is arranged on the side wall of the box body 1 and communicates the inside and outside of the box body 1, a manual air release valve is arranged at the outer end of the air guide pipe, an air breathing valve is arranged at the inner end, and a waterproof air permeable diaphragm is arranged in the air guide pipe.
