[0002] Blood delivery devices are crucial equipment for clinical blood use, emergency rescue, and the distribution of blood products. They directly affect the quality, safety, and timeliness of blood from blood banks to medical institutions and from storage points to patients. They not only maintain the low-temperature environment required for blood transportation to prevent component inactivation, but also ensure that blood is not contaminated and blood bags are not damaged through reliable protection. They are a key link connecting blood supply and clinical treatment, and play an irreplaceable role in reducing the risk of transfusion delays in emergency treatment scenarios and ensuring patient safety.

[0003] Current blood delivery devices suffer from insufficient adaptability to various scenarios. In conventional settings, these devices often utilize a single material with limited impact resistance. In emergency situations or outdoor rescue operations, drops or collisions can easily rupture the internal blood bags and damage red blood cells. The problem becomes even more pronounced in special scenarios such as emergency rescue and large-scale disaster relief. When roads are blocked and air delivery via drones or helicopters is necessary, existing devices lack reinforced protective structures adapted for aerial transport. The impact of a high-altitude descent can be directly transmitted to the internal components, leading to damage to blood components. Utility Model Content

[0015] This utility model has the following advantages due to the adoption of the above technical solution: The blood delivery device provided by this utility model includes a blood storage device, an insulated bag, a first buffer box, a second buffer box, and a third buffer box. The blood storage device includes a blood storage isolation bag, a cooling device, and a first cushioning material. The first cushioning material is used to wrap around the outside of the blood bag during low-altitude or high-altitude delivery, filling the space between the blood storage isolation bag and the blood bag. This prevents the blood bag from shaking inside the blood storage isolation bag during low-altitude or high-altitude delivery, and the first cushioning material also absorbs impact, reducing the impact on the internal blood bag. However, the first cushioning material is not necessary for short-distance transport by drone.

The combination of the first, second, and third buffer boxes, the first buffer material between the blood bag and the blood storage isolation pack, the second buffer material between the first and second buffer boxes, and the third buffer material between the second and third buffer boxes ensure that the blood and the device remain intact after delivery from a height of 100 meters. The blood delivery device provided by this utility model achieves flexible scenario adaptation through a modular structure. Different structural combinations are adopted for different aerial delivery scenarios to meet diverse protection needs such as short-distance drone delivery, 10-meter height delivery, and 100-meter height delivery scenarios.

The combination of the first, second, and third buffer boxes, the first buffer material between the blood bag and the blood storage isolation pack, the second buffer material between the first and second buffer boxes, and the third buffer material between the second and third buffer boxes ensure that the blood and the device remain intact after delivery from a height of 100 meters. The blood delivery device provided by this utility model achieves flexible scenario adaptation through a modular structure. Different structural combinations are adopted for different aerial delivery scenarios to meet diverse protection needs such as short-distance drone delivery, 10-meter height delivery, and 100-meter height delivery scenarios. There is no need to design separate devices for different delivery scenarios, which reduces research and development and production costs and improves the applicability and reliability of the device in emergency rescue, disaster relief, and other scenarios.

[0026] The following is combined with Figures 1 to 8 This invention describes a blood delivery device.

[0027] An embodiment of this utility model provides a blood delivery device, including a blood storage device 400, a first buffer box 100, an insulated bag, a second buffer box 200, and a third buffer box 300.

[0028] The blood storage device 400 includes a blood storage isolation bag 410, a cooling device, and a first cushioning material. The first cushioning material does not need to be added during short-distance transport by drone. It can be used to wrap the outside of the blood bag during low-altitude or high-altitude blood delivery. The blood bag wrapped with the first cushioning material is placed inside the blood storage isolation bag 410, and the first cushioning material fills the space between the blood bag and the blood storage isolation bag 410 to prevent the blood bag from shaking inside the blood storage isolation bag 410 during low-altitude or high-altitude delivery. When the blood storage isolation bag 410 is subjected to external impact, the first cushioning material can absorb the impact force transmitted to the blood bag, reducing the impact on the blood bag. The cooling device is located inside the blood storage isolation bag 410 to create a low-temperature environment inside the blood storage isolation bag 410 to prevent the blood components from becoming inactive. This blood storage device 400 can simultaneously achieve low-temperature blood storage and physical isolation between the blood bag and the cooling device.

[0029] The first buffer box 100 is used to place the blood storage device 400. The insulated bag can be used to hold the first buffer box 100. The first buffer box 100 and the insulated bag have good heat preservation performance, which can extend the time of maintaining the low temperature environment inside the blood storage isolation bag 410, thereby ensuring the quality of the blood delivered on the ground.

[0030] The second buffer box 200 can be used to place at least one first buffer box 100. After one or more first buffer boxes 100 are placed inside the second buffer box 200, a second buffer material needs to be filled into the space between the inner wall of the second buffer box 200 and the outer wall of the first buffer box 100, as well as between two adjacent first buffer boxes 100. When the outside of the second buffer box 200 is subjected to an impact, the second buffer material can absorb part of the impact force to prevent the entire impact force from being transmitted to the first buffer box 100.

[0031] The third buffer box 300 is used to house the second buffer box 200. After the second buffer box 200 is placed inside the third buffer box 300, a third buffer material needs to be filled into the space between the inner wall of the third buffer box 300 and the outer wall of the second buffer box 200. When the outside of the third buffer box 300 is subjected to an impact, the third buffer material can absorb part of the impact force to prevent the entire impact force from being transmitted to the second buffer box 200.

[0032] The blood delivery device provided by this utility model can be used for blood delivery in at least the following three scenarios: First, in the scenario of short-distance delivery by drone: the first buffer box 100 is used alone and is placed in an insulated bag. Its lightweight characteristics are adapted to the drone's payload limitations. At the same time, the heat preservation performance of the first buffer box 100 and the insulated bag ensures the quality of the blood delivered upon landing.

[0033] Second, in the scenario of delivery from a height of 10 meters: a combination of a first buffer box 100 and a second buffer box 200 is used. The second buffer material between the first buffer box 100 and the second buffer box 200, as well as the first buffer material wrapped around the outside of the blood bag, can absorb the impact energy of a drop from a height of 10 meters, preventing the blood bag from breaking and ensuring the quality of the blood.

[0034] Third, in the 100-meter height delivery scenario: a three-layer combination of first buffer box 100, second buffer box 200 and third buffer box 300 is adopted. The combination of first buffer box 100, second buffer box 200 and third buffer box 300, the first buffer material between blood bag and blood storage isolation bag 410, the second buffer material between first buffer box 100 and second buffer box 200, and the third buffer material between second buffer box 200 and third buffer box 300 can ensure that the blood and device remain intact after delivery from a height of 100 meters.

[0035] The blood delivery device provided by this utility model achieves flexible scenario adaptation through a modular structure. Different structural combinations are adopted for different aerial delivery scenarios to meet diverse protection needs such as short-distance delivery by drones, delivery at a height of 10 meters, and delivery at a height of 100 meters. There is no need to design separate devices for different delivery scenarios, which reduces research and development and production costs and improves the applicability and reliability of the device in emergency rescue, disaster relief and other scenarios.

[0036] In some embodiments, the cooling device may include a housing and a water-based refrigerant encapsulated within the housing, namely an ice box 420. The ice box 420 can be frozen in a refrigerator before use.

[0037] In some embodiments, the first buffer box 100, the second buffer box 200 and the third buffer box 300 each include a box body 710, a box cover 720 and strapping straps 730.

[0038] The container 710 can be a rectangular structure with an open top, allowing objects to be placed or removed from the container 710 through its top. A lid 720 is closable on the top of the container 710, allowing the container 710 to be closed or opened. A strapping 730 is used to secure the container 710 and lid 720 assembly to the outside of the container when the lid 720 is fastened to the top of the container 710, preventing the lid 720 from opening abnormally during delivery and further ensuring the safety of blood delivery.

[0039] In some embodiments, the first buffer box 100 may be made of EPP material, the second buffer box 200 may be a rotomolded box, and the third buffer box 300 may be a honeycomb cardboard box or a corrugated cardboard box.

[0040] EPP material offers excellent thermal insulation, ensuring the quality of blood delivered upon landing. Its lightweight nature also reduces the overall weight of the blood delivery device, making it compatible with drone payload limitations. The rotomolded box boasts high impact resistance, capable of withstanding the impact of a 10-meter drop. Honeycomb or corrugated cardboard boxes break upon impact with the ground, thus dispersing the impact force.

[0041] In some embodiments, the first cushioning material may include at least a cushioning sponge and an air column bag, wherein the cushioning sponge is used to wrap around the outside of the blood bag and the air column bag is used to wrap around the outside of the sponge, thereby providing double-layer cushioning protection for the blood bag.

[0042] In some embodiments, the second and third cushioning materials may include at least one of cushioning sponge and inflatable column.

[0043] In some embodiments, a temperature detection device is also provided on the first buffer box 100, which is used to detect the temperature inside the blood storage isolation pack 410. The temperature detection device includes a temperature probe and a display screen. The temperature probe is inserted into the blood storage isolation pack 410 to detect the temperature inside the blood storage isolation pack 410. The display screen is located on the outside of the first buffer box 100 and is communicatively connected to the temperature probe. The display screen can be used to display the real-time temperature inside the blood storage isolation pack 410. Medical personnel can confirm whether the temperature inside the blood storage isolation pack 410 is within the temperature range for blood storage before blood collection, so as to predict the blood quality.

[0044] In addition, a label bar 600 is provided on the outside of the first buffer box 100. The label bar 600 is used to insert labels, and the labels are used to record blood information and time information.

[0045] The following will disclose the simulation methods for different usage scenarios of this blood delivery device: First, short-range drone delivery scenarios Remove the ice pack 420 and blood bag from the refrigerator. Open the blood storage isolation bag 410 and place the blood, which needs to be delivered by drone over a short distance, into it in an orderly manner. Place the ice pack 420, which has been equilibrated at room temperature for 5 minutes, on top of the blood storage isolation bag 410. Open the first buffer box 100 and place the blood storage isolation bag 410 inside. Before placing it in, insert the probe of the temperature detection device into the blood storage isolation bag 410. Place the blood storage isolation bag 410 flat on the first buffer box 100, close the lid, and finally secure it with the strapping 730. Then, place the first buffer box 100 into the insulated bag for delivery.

[0046] Second, the 10-meter low-altitude delivery scenario. Remove the ice pack 420 and blood bag from the refrigerator. Wrap the standard blood bag with a cushioning sponge folded into a bag shape for protection. The opening of the sponge bag should face the same direction as the blood bag. Place the entire bag into a 30% inflated air column bag, ensuring that the openings of the sponge bag and air column bag are facing upwards and the blood bag is facing upwards when placed into the blood storage isolation pack 410. Finally, place the ice pack 420, which has been equilibrated at room temperature for 5 minutes, into the top and bottom of the blood storage isolation pack 410.

[0047] Open the first buffer box 100 and put in the blood storage isolation bag 410. Before putting it in, the probe of the temperature detection device should be inserted into the blood storage isolation bag 410. After placing the blood storage isolation bag 410 flat on the first buffer box 100, close the lid and finally tie it securely with the strapping 730.

[0048] Then open the rotomolded box, i.e. the second buffer box 200. Place a sponge block at the bottom of the second buffer box 200. Put the first buffer box 100 from the previous scene into the second buffer box 200. Lay sponge blocks on the top and sides. Then put in another first buffer box 100. Add sponge blocks on the top and sides. Fasten the box lid 720. Finally, reinforce the rotomolded box with straps 730.

[0049] The container module was subjected to a 10-meter drop test, with one drop. The ground conditions were gravel and hard cement. After the test, the container module did not break apart, the packaging was undamaged, and the blood bags inside were undamaged. The blood quality after storage and transportation met GB18469-2012, and the hemolysis rate was less than 0.8%.

[0050] Third, the 100-meter high-altitude delivery scenario. Repeat the steps from the previous scenario, assemble the honeycomb cardboard into a box shape, and secure it firmly with tape. Leave the top opening open temporarily, and insert inflatable columns or sponges for protection at the bottom.

[0051] Place the bundled blood delivery device, which is delivered from a height of 10 meters, into the honeycomb cardboard box. Add air columns or sponges for protection on the top and sides. Seal the top cover of the honeycomb cardboard box to form a third buffer box 300 and secure it with tape. Finally, reinforce the third buffer box 300 with strapping 730.

[0052] The container module was subjected to a 100-meter safety drop test, with one drop. The ground conditions were gravel and hard cement. After the test, the container module did not break apart, the packaging was undamaged, and the blood bags inside were undamaged. The blood quality after storage and transportation met the requirements of GB18469-2012, with a hemolysis rate of less than 0.8%.

[0053] The blood quality test results showed that the hemolysis rate gradually increased with the extension of storage time during the storage period. In particular, the hemolysis rate rose rapidly in the short period after airdrop, showing a significant difference from that before airdrop, indicating that airdrop caused a certain degree of hemolysis. By the end of the storage period, the hemolysis rate of suspended red blood cells in the 10m airdrop group remained between 0.035% and 0.328%, and the hemolysis rate of suspended red blood cells in the 100m airdrop group remained between 0.035% and 0.337%, both meeting the quality requirements of GB18469-2012 for whole blood and blood components (<0.8% of total red blood cells).

[0054] The above embodiments are only examples of suspended red blood cells. In practice, this delivery device can also be applied to the delivery of whole blood, etc.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
