Description

Technical Field

[0001] This utility model relates to the field of blood delivery protection technology, specifically a blood delivery protective packaging system. Background Technology

[0002] Blood delivery protective packaging systems typically refer to the safe and contamination-free transport and storage of blood in medical settings. Their core objective is to ensure that blood remains effective, avoids contamination, and is protected against abnormal temperatures and mechanical damage throughout the entire process from collection, transport, storage to transfusion.

[0003] In existing technologies, during blood delivery, collisions can easily occur inside the container, causing blood leakage and affecting the integrity of the blood delivery.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN217436475U) discloses an airdrop-type blood transport box, including a lid, a box body, and a sealing buckle. The lid is rectangular with handles on both sides and a limiting protrusion at one end. The box body is cuboid with an opening at one end and a limiting groove at the bottom. The lid and box body are connected by a locking buckle. The box body and lid are filled with polyurethane foam insulation material. The sealing buckle is connected to the lid at one end and to the box body at the other end. The sealing buckle can be adjusted to achieve a completely tight seal, significantly improving the temperature control time. The concave-convex design of the top of the lid and the bottom of the box body enhances stability during stacking during transportation, facilitating bulk airdrops. The airdrop-type blood transport box meets airdrop requirements in terms of size and material strength, and can be used with various airdrop systems. Equipped with matching phase change materials and shock-absorbing bags, it does not require a power supply and can airdrop blood to low-pressure, high-altitude, cold, and high-temperature areas.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, during the transportation of blood delivery boxes, the internal temperature of the blood is easily lost due to long-term transportation. After the temperature is lost, the blood may lose its activity, affecting its subsequent use. Utility Model Content

[0006] The purpose of this invention is to provide a protective packaging system for blood delivery, in order to solve the problem mentioned in the background art that during the transportation of blood delivery boxes, the internal temperature of the blood is easily lost due to long-term transportation, which can cause the blood to lose its activity and affect its subsequent use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a blood delivery protective packaging system, including a rotomolded outer box and a lid at the top of the rotomolded outer box. An insulated inner bag is provided inside the rotomolded outer box, and a protective packaging mechanism is provided between the insulated inner bag and the rotomolded outer box. The rotomolded outer box protects the blood bag inside the insulated inner bag through the protective packaging mechanism. A blood storage isolation bag is provided inside the insulated inner bag, and a vibration damping and heat preservation mechanism is provided between the blood storage isolation bag and the insulated inner bag. The blood storage isolation bag maintains the temperature of the blood bag while also providing vibration damping through the vibration damping and heat preservation mechanism.

[0008] Furthermore, the opening of the rotomolded outer box is provided with a latch, and the upper end of the latch is engaged with the corresponding position of the box lid.

[0009] Furthermore, the surfaces of the rotomolded outer box and the box lid are wrapped with polyester strapping, and the polyester strapping is distributed in a crisscross pattern.

[0010] Furthermore, the protective packaging mechanism is provided with an inner convex ring, and the lower end of the inner convex ring is fixedly installed on the upper end of the rotomolded outer box. The rotomolded outer box is located inside the box cover, and a sealing strip is fixedly installed inside the box cover, with the position of the sealing strip corresponding to the inner convex ring.

[0011] Furthermore, the inner walls of both the rotomolded outer box and the box cover are provided with shock-absorbing and heat-insulating plates, and the inner side of the shock-absorbing and heat-insulating plates is attached to the outer side of the heat-insulating inner package, and a layer of heat-insulating cotton is provided on the inner side of the shock-absorbing and heat-insulating plates.

[0012] Furthermore, the vibration damping and heat preservation mechanism is equipped with a buffer air column, which is positioned between the heat preservation inner bag and the blood storage isolation bag, and ice packs are provided on both the front and rear sides of the blood storage isolation bag.

[0013] Furthermore, the surface of the insulated inner bag is provided with a waterproof zipper, the front end of the insulated inner bag is provided with a storage bag, the top end of the insulated inner bag is provided with a carrying handle, and the inner wall of the insulated inner bag is provided with insulation cotton.

[0014] Furthermore, a temperature monitoring device is provided on the outside of the thermal insulation inner package, and the sensor of the temperature monitoring device is located on the inside of the thermal insulation inner package. A balance valve is provided on the right side of the rotomolded outer box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When using this blood delivery protective packaging, the shock-absorbing and heat-insulating plates installed on the rotomolded outer box and the inner wall of the box lid can form all-round buffering and temperature protection for the items inside the box. The shock-absorbing and heat-insulating plates are made of high-density sponge material, which not only has excellent impact absorption performance, but also effectively blocks external temperature conduction and maintains a constant temperature environment inside the box. The shock-absorbing and heat-insulating module meets the dual requirements of protection and heat preservation while being lightweight. A layer of heat-insulating cotton is also installed on the inner side of the shock-absorbing and heat-insulating plates. Through the cooperation of the heat-insulating cotton and the shock-absorbing and heat-insulating plates, it is not only easy to transport and handle, but also significantly reduces the risk of blood bag collision and rupture caused by shaking, ensuring the integrity and safety of blood products during transportation.

[0017] Furthermore, when the lid is closed with the rotomolded outer box, a multi-point locking mechanism around the box body enables quick and easy fastening. This, combined with the crisscrossing polyester strapping system inside the box, provides double protection. The annular groove on the top of the lid and the inner convex ring at the opening of the rotomolded outer box form a precise fit. During the locking process, the sealing strip embedded in the inner wall of the lid and the inner convex ring exert a tight pressure, effectively preventing external liquid from seeping in and internal temperature from leaking out, ensuring stable internal storage conditions even in complex transportation environments.

[0018] 2. During airdrop operations, a rapid, parachute-free airdrop mode can be adopted, directly deploying the blood products via a drone platform, effectively ensuring the efficient transportation of blood products during medical rescue operations. The rotomolded outer box is made of linear low-density polyethylene, a material with excellent impact resistance and low-temperature resistance, making it particularly suitable for protecting internal supplies during airdrops. Furthermore, the corners of the box are locally thickened using the rotomolding process, further enhancing its ability to withstand the enormous impact loads of high-altitude falls. Tests have shown that this parachute-free airdrop system maintains structural integrity even when deployed at a height of 110 meters (based on a helicopter), fully ensuring the effectiveness of the internal cushioning and shock absorption system. The rotomolded outer box designed in this research significantly improves the emergency storage and transportation capabilities for blood. Its manufacturing process and transportation procedures are standardized and modularized, better meeting the medical support needs in emergency situations and holding significant strategic importance for improving the level of emergency blood supply under the new circumstances.

[0019] Furthermore, in high-altitude, frigid regions where blood supplies are needed, transporting blood to designated locations via drones and then directly airdropping it without a parachute can significantly save manpower and achieve extremely rapid delivery. This parachute-less airdrop design also features high directional stability, effectively reducing delivery location deviations and ensuring that blood products are delivered quickly and accurately to designated treatment points, buying precious time for patient rescue.

[0020] Furthermore, linear low-density polyethylene maintains its flexibility even under extreme low-temperature conditions ranging from -40°C to -60°C, effectively preventing the rotomolded outer casing from becoming brittle and cracking in high-altitude environments. This perfectly adapts to the requirements of high-altitude and low-temperature conditions, ensuring that the quality of blood after transportation fully complies with the provisions of GB18469-2021 "Quality Requirements for Whole Blood and Blood Components". This current national standard, issued by the Standardization Administration of China, mainly regulates the following: blood component preparation must comply with specific process specifications, clarifying the standards for the use of additives such as anticoagulants and glucose; blood products must undergo strict quality monitoring, including key indicators such as hemoglobin content determination and bacterial contamination detection; and blood component separation technology must meet separation efficiency and purity requirements to effectively ensure the safety and effectiveness of clinical blood use. During transportation, the WS / T400-2023 "Blood Transportation Standard" is strictly implemented. This health industry standard clearly stipulates that, according to the characteristics of different blood components, the transportation temperature must be precisely controlled within the specified range of 2℃~10℃ (whole blood and red blood cells), frozen state (plasma), and 20℃~24℃ (platelets and granulocytes). Temperature-controlled vehicles or special transport boxes must be used for transportation, and blood products with different temperature requirements must be loaded in separate boxes. It is strictly forbidden to mix them with other items during transportation to ensure that the blood quality meets the requirements after transportation.

[0021] 3. The inner insulation pack adopts a multi-layer composite structure, with high-quality insulation cotton filling the inner wall to form a continuous insulation layer. When transporting blood bags, the blood bags can be properly placed in the special blood storage isolation pack. The insulation cotton achieves continuous temperature protection for the blood bags by controlling heat conduction. The front and back sides of the blood storage isolation pack are specially equipped with detachable ice packs. These side-by-side ice packs can be filled with phase change refrigerant or customized ice blocks. Through the continuous release of refrigerant, long-term temperature control is achieved to meet the differentiated temperature requirements of different blood products during transportation.

[0022] Furthermore, an array of buffer air columns is embedded in the gap between the insulated inner bag and the blood storage isolation bag. These air columns are formed by a high-strength composite film through a precision inflation process. Through the elastic support of the air columns, a flexible protective layer is formed between the box and the blood bag. This design not only enhances the overall insulation performance, but also effectively alleviates vibration and impact during transportation through the deformation absorption mechanism of the air columns, providing double protection for the blood bag and minimizing the probability of blood bag damage due to bumps and collisions, thus ensuring the quality and safety of blood products during long-distance transportation.

[0023] Furthermore, an intelligent temperature monitoring device is integrated on the left side of the insulated inner enclosure. This device integrates a main control display module, a high-precision temperature recording module, and a digital sensor, which can monitor and display the internal temperature data in real time. The temperature curve and extreme value records are clearly presented on the LCD screen on the surface of the device. The built-in balance valve structure is designed for high-altitude and low-pressure environments. Before opening the enclosure, the air pressure can be adjusted through the balance valve to achieve safe depressurization, effectively avoiding the enclosure from bursting open or operator injury due to excessive internal and external pressure difference. This significantly improves the safety and convenience of use in special areas such as high-altitude regions. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1: As Figures 1-5 The technical solution shown is a blood delivery protective packaging system. In order to solve the problem of poor protective effect, the system discloses: a rotomolded outer box 1 and a box cover 2 set at the upper end of the rotomolded outer box 1. The rotomolded outer box 1 is provided with an insulated inner bag 10 inside, and a protective packaging mechanism is provided between the insulated inner bag 10 and the rotomolded outer box 1. The rotomolded outer box 1 protects the blood bag inside the insulated inner bag 10 through the protective packaging mechanism. The insulated inner bag 10 is provided with a blood storage isolation bag 11 inside.

[0036] The opening of the rotomolded outer box 1 is provided with a latch 3, and the upper end of the latch 3 is engaged with the corresponding position of the box cover 2. The surfaces of the rotomolded outer box 1 and the box cover 2 are wrapped with polyester strapping 4, and the polyester strapping 4 is distributed in a crisscross pattern. The protective packaging mechanism is provided with an inner convex ring 7, and the lower end of the inner convex ring 7 is fixedly installed on the upper end of the rotomolded outer box 1. The rotomolded outer box 1 is located inside the box cover 2. A sealing strip 8 is fixedly installed inside the box cover 2, and the position of the sealing strip 8 corresponds to the inner convex ring 7. The inner walls of the rotomolded outer box 1 and the box cover 2 are provided with shock-absorbing and heat-insulating plates 9, and the inner side of the shock-absorbing and heat-insulating plates 9 is attached to the outer side of the heat-insulating inner package 10. A layer of heat-insulating cotton is provided on the inner side of the shock-absorbing and heat-insulating plates 9.

[0037] When using this blood delivery protective packaging, the lid 2 is closed onto the rotomolded outer box 1. The lid 2 is secured by the latches 3 between the rotomolded outer box 1 and the lid 2, and further secured by the crisscrossing polyester straps 4. This firmly protects the blood bag inside the rotomolded outer box 1. When the lid 2 is installed on the rotomolded outer box 1, the groove at the top of the lid 2 engages with the inner protruding ring 7 on the rotomolded outer box 1. At this time, the sealing strip 8 on the inner wall of the lid 2 presses against the inner protruding ring 7, achieving a seal and ensuring sealing efficiency. The sealing design between the rotomolded outer box 1 and the lid 2 effectively isolates moisture and salt spray corrosion, protecting the blood inside the rotomolded outer box 1. The shock-absorbing and heat-insulating plates on the inner walls of the rotomolded outer box 1 and the lid 2 further enhance the seal. The rotomolded outer box 1 is designed to protect the contents inside. The shock-absorbing and heat-insulating plate 9 is made of sponge, which provides both protection and insulation, meeting practical needs. The sponge is also lightweight, making it easier to handle and reducing the risk of blood bags rupturing upon impact. An inner layer of insulation cotton is also added to the shock-absorbing and heat-insulating plate 9. Through the combined action of the insulation cotton and the shock-absorbing and heat-insulating plate 9, the internal temperature can be maintained between 2 and 10 degrees Celsius for up to 12 hours, significantly enhancing the insulation effect. Furthermore, it allows for rapid, umbrella-less airdrops from drones, ensuring blood transport and enabling quick delivery during medical disaster relief. The rotomolded outer box 1 is made of linear low-density polyethylene. Made from this material, which possesses superior impact resistance and low-temperature resistance, it is suitable for protecting internal supplies during airdrops. Furthermore, the rotomolded outer casing 1 is thickened at its corners through a rotomolding process, further enhancing its ability to withstand the immense impact of high-altitude falls. It can withstand a drop of up to 110 meters without a parachute (this data is based on the height from the bottom of the blood delivery protection system to the ground), effectively ensuring the cushioning and shock absorption effect inside the rotomolded outer casing 1 during parachute-less airdrops. The rotomolded outer casing 1 used in this study significantly improves the emergency storage and transportation capabilities of blood. Moreover, its manufacturing and transportation processes can be standardized and modularized, better enabling medical support under emergency conditions. This is of great significance for improving emergency blood supply capabilities in the new era. Linear low-density polyethylene can withstand temperatures as low as -60 degrees Celsius. Even in extreme low-temperature environments, linear low-density polyethylene (LLDPE) maintains its flexibility, preventing the rotomolded outer box from becoming brittle and cracking during airdrops without parachutes in high-altitude environments. This ensures the transported blood meets the requirements of GB18469-2021, a currently effective national standard entitled "Quality Requirements for Whole Blood and Blood Components." Issued by the Standardization Administration of China, this standard regulates the quality control requirements for whole blood and blood components by blood banks. It primarily covers the following core requirements: blood component preparation must comply with specific process specifications, including the standards for the use of additives such as anticoagulants and glucose; blood products must undergo rigorous quality monitoring, such as hemoglobin content and bacterial contamination testing.Blood component separation technology must meet requirements for separation efficiency and purity to ensure the safety and effectiveness of clinical blood use. During transportation, the industry standard WS / T400-2023 must be followed. WS / T400-2023 is a national health industry standard, officially titled "Blood Transportation Standard," which mainly regulates the transportation requirements of blood between different institutions or different branches of the same institution. This standard specifies key aspects of blood transportation, including temperature control, transportation methods, and equipment requirements. Temperature control: Depending on the blood type and composition, the transportation temperature must be strictly controlled within the range of 2℃~10℃ (whole blood and red blood cells), frozen state (plasma), and 20℃~24℃ (platelets and granulocytes). Transportation methods: Temperature-controlled vehicles or special transport containers must be used, and blood with different temperature requirements must be transported separately. Mixing with other items is prohibited. In high-altitude, frigid regions where blood is needed, it can be transported to the designated location by drone and then airdropped directly. This saves manpower, has a high delivery speed, and the umbrella-less airdrop design makes it less likely to deviate from the designated location, ensuring that blood is quickly delivered to the designated location for patient assistance.

[0038] Example 2: Figures 1-9 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of poor heat preservation: a vibration damping and heat preservation mechanism is provided between the blood storage isolation bag 11 and the heat preservation inner bag 10, and the blood storage isolation bag 11 maintains the temperature of the blood bag through the vibration damping and heat preservation mechanism.

[0039] The vibration damping and heat preservation mechanism is equipped with a buffer air column 15, which is positioned between the heat preservation inner bag 10 and the blood storage isolation bag 11.

A balance valve 6 is provided on the right side of the rotomolded outer box 1.

[0040] An insulated inner bag 10 is installed inside the rotomolded outer box 1. The insulated inner bag 10 can be used alone or used with the rotomolded outer box 1 for high-altitude delivery. The insulated inner bag 10 is lined with insulating cotton. When transporting blood bags, the blood bags are placed inside the blood storage isolation bag 11 inside the insulated inner bag 10. The insulating cotton keeps the blood bags warm. Ice pack bags 16 are installed on the front and back sides of the blood storage isolation bag 11. Ice can be placed inside the side-by-side bags to keep the blood bags warm. At the same time, a buffer air column 15 is installed between the insulated inner bag 10 and the blood storage isolation bag 11. The buffer air column 15 is filled with air from the existing plastic film to support and protect the insulated inner bag 10 and the blood storage isolation bag 11. It has both insulation and protection effects, reducing the risk of blood bags breaking upon impact. The surface of the insulated inner bag 10 is sealed with a waterproof zipper 12. The opening and closing mechanism is simple and convenient to operate. A storage bag 13 is located at the front of the insulated inner bag 10, allowing for the storage of some items. A carrying handle 14 is located at the top of the insulated inner bag 10, enabling convenient carrying and transport. It provides effective insulation. A temperature monitoring device 5 is located on the outside of the insulated inner bag 10. This device includes a main control display module, a temperature recording module, and sensors, displaying the internal temperature of the insulated inner bag 10. The device displays the internal data on a screen on its surface. A balance valve 6 is located on the right side of the rotomolded outer box 1. This valve meets the needs of high-altitude operations, facilitating opening the box. It automatically depressurizes before opening the rotomolded outer box 1, preventing it from being unable to open.
