[0029] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 4 As shown, the blood box transport box is a constant temperature device used to store and transport blood, especially a constant temperature blood box that can meet the requirements of military standards for the storage and transportation of blood required by combatants in modern anti-terrorism wars and field combat.

[0032] The blood box transport box disclosed in the present invention includes a box body 1 and a box cover 2 that can be sealed and fastened to the box body 1, and the box body 1 and the box cover 2 are fixed by means of a lock. A handle, a nameplate, a blood type label frame, etc. are provided on the outside of the box body 1. The top of the box cover 2 and the bottom of the box body 1 are designed with specified standard concave and convex ribs to meet the storage and stacking requirements. The box cover 2 and the box body 1 are matched with each other in a stepped manner, and a circle of sealing grooves is also provided on the box cover 2, and a sealing ring is embedded in the sealing groove. A circle of raised parts that can be embedded in the sealing groove and squeeze the sealing ring is provided on the box body 1, thereby forming an airtight, waterproof and sealed structure. The sealing strip is made of silicone material, which has moderate hardness, low water absorption, and is resistant to aging, and realizes pressure-free airtight sealing from the aspects of material and structural design.

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

[0034] Several hollow blood storage baskets 3 are neatly stacked in the inner cavity of the box body 1. The blood storage basket 3 can be made of steel mesh. Shock-absorbing pads 31 are fixed to the side walls and bottom walls of the blood storage basket 3, preferably silicone shock-absorbing pads. The shock-absorbing pads 31 at the bottom of the blood storage basket 3 are cylindrical blocks, which can be rotatably fixed on the blood storage basket 3. When the vehicle is bumpy or braked suddenly, the blood storage basket 3 is displaced first, avoiding collision between the blood bag and the blood storage basket 3. The setting of the shock-absorbing pads 31 avoids hemolysis caused by vibration during blood transportation, and has a certain shock-absorbing effect. It can be used to ensure that the blood station can complete the blood transportation task under harsh road conditions and improve the emergency storage and transportation and guarantee capabilities of blood.

[0035] In one preferred embodiment, blood bags are stacked using four compartmentalized blood baskets that fill a blood transport box. Each blood storage basket (3) can accommodate 25 100ml blood bags in two rows, stacked in two layers within the box to prevent squeezing. During storage, the filled blood baskets are placed into the box one by one.

[0036] A cold storage ice pack is placed between the box 1 and the blood storage basket 3. Using the box 1 for insulation, the ice pack, which contains a phase change agent, passively adjusts and controls the temperature inside the box, ensuring that the blood transport box maintains temperature control within a specified timeframe. This includes side ice packs 41 placed between the blood storage basket 3 and the side walls of the box 1, and an upper ice pack 42 placed between the top of the blood storage basket 3 and the box lid 2. A thermal insulation pad 43 is secured to the lower surface of this upper ice pack 42.

[0037] The blood transport box also includes a temperature monitoring system, which includes a temperature sensor placed in the box body 1 and a controller electrically connected to the temperature sensor. The controller has 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 in the temperature recording module. The temperature record can be reviewed before blood transfusion to ensure the safety of blood transfusion.

[0038] Furthermore, the battery selection for temperature monitoring systems also requires low-temperature adaptability. For ease of use, we selected low-temperature-resistant lithium batteries in accordance with GJB / Z 53.2-94, "Military Battery Series Lithium Batteries." To ensure safety and ease of use in cold regions at -41°C, we designed a battery storage tank within the system. This allows the internal temperature to drop to a minimum of -20°C during low-temperature operation, mitigating the impact of the -41°C temperature drop on battery performance.

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

[0040] ①Spray a shielding film layer on the controller and affix a shielding film on the display panel to eliminate dead angles and provide protection.

[0041] ②Sensor line protection: The sensor line is connected with shielded wires, and attention should be paid to the electromagnetic shielding protection at the joints;

[0042] ③Battery circuit protection: design shielding protection measures for battery box and connecting lines;

[0043] ④In PCB design, strictly implement EMC / EMI related rules.

[0044] The overall design meets the relevant requirements of GJB 151B-2013 "Electromagnetic Emission and Sensitivity Requirements and Measurements for Military Equipment and Subsystems".

[0045] The inner wall of the blood transport box body 1 is provided with raised ribs, and passages for air circulation are formed between the ribs. The blood storage bags are placed in a plurality of blood storage baskets 3. There are also gaps for air circulation between the blood storage baskets 3 through the arrangement of shock-absorbing pads 31, so that the air in the inner cavity of the box body 1 can circulate and the temperature is balanced.

[0046] The blood transport box is filled with ice packs on the periphery of the blood storage basket 3. The ice packs isolate the external temperature and have a certain temperature control ability, which can quickly make the temperature inside the box reach the required level. In addition, the side ice packs 41 are prevented from direct contact with the blood bags by the blood storage basket 3, and the upper ice packs 42 are prevented from direct contact with the blood bags by bonding with the insulation pads 43. It has refrigeration and freezing insulation properties, providing safe storage protection for whole blood and the like within a specified time.

[0047] The blood bags are packaged separately, which reduces the collision damage between the blood bags caused by bumpy road conditions during transportation. In addition, each blood storage basket 3 is cushioned and shock-absorbing by the provided shock-absorbing pads 31, which further avoids damage to the blood bags.

[0048] The box body 1 and / or lid 2 have a sandwich structure, filled with insulation panels 5. These panels are preferably vacuum insulation panels, offering excellent thermal insulation performance with a thermal conductivity of less than 0.002 W / mK, providing primary insulation. The remaining gaps in the shell are then filled with conventional insulation materials, forming a complete insulated shell system that not only meets insulation requirements but also provides support and cushioning, ensuring load-bearing and shock absorption, ensuring safe transportation. The outer and inner shells of the blood transport box are constructed from carbon fiber, meeting the performance requirements of complex service environments, achieving significant weight reduction, and exhibiting excellent resistance to high and low temperatures.

[0049] To ensure the neatness of the stacking of the blood storage baskets 3, a positioning member 6 is provided between the upper and lower blood storage baskets 3. The positioning member 6 includes angled members fixed to the four corners of the top of the lower blood storage basket 3. The angled members protrude upward from the lower blood storage basket 3. The angled members can position the two stacked blood storage baskets 3 and prevent collisions between the blood storage baskets 3 during shaking.

[0050] In one preferred embodiment, each cold storage ice row 2 covers the top of a blood storage basket 3. When taking blood, the ice row 42 on one side is opened, and the blood can be taken in pieces or in whole as needed, which is flexible and convenient.

[0051] The blood transport box has plateau adaptability requirements and can operate normally in areas with an altitude of not less than 4,500 meters. An air pressure regulating valve is designed on the short side of the blood transport box so that the packaging box can meet the needs of plateau work. An air duct 7 is provided on the side wall of the box body 1 to connect the inside and outside of the box body 1. A manual air release valve is provided at the outer end of the air duct, a breathing valve is provided at the inner end, and a waterproof and breathable membrane is provided inside the air duct. The internal breathing valve with a waterproof semi-permeable membrane is operated through a conduit and an external manual regulating valve. It is breathable but not water-permeable, meeting the watertight and breathable functions, and can be closed at the same time to ensure that the inside and outside are sealed during storage, adapting to various environmental changes, especially the pressure adjustment in the box under plateau conditions, and convenient unpacking operations.

[0052] The above are only preferred embodiments of the present invention. Any simple modification, deformation and equivalent replacement made by anyone to the present invention based on the content of the present invention shall fall within the protection scope of the present invention.
