Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please refer to Figures 1-4. The present invention provides a technical solution: a portable cryogenic organ preservation and transport box that can bridge kidney repair surgery, including a box body 110. The four corners of the bottom of the box body 110 are equipped with pulleys, and a handle 111 is installed on one side of the box body 110. A sealing cover 120 is snapped onto the top of the box body 110. The box body 110 is divided into a refrigeration area and a control area by a partition 112. A refrigeration component 130 and a battery pack 131 that are electrically connected to each other are symmetrically fixed at the bottom of the inner wall of the control area. The output end of the refrigeration component 130 passes through the partition 112 and communicates with the refrigeration area. A U-shaped air guide 132 is fixedly installed on the inner wall of the refrigeration area. Air inlets 133 are provided at the top of both sides of the air guide 132. A storage box 140 is slidably installed on the inner wall of the refrigeration area. A lifting component is installed at the bottom of the storage box 140.

[0027] In some specific implementations, the refrigeration component 130 uses a miniature refrigeration compressor to achieve the refrigeration function. Ventilation screens are symmetrically arranged on both sides of the control area, and a buffer pad is installed at the bottom of the miniature refrigeration compressor. The ventilation screens provide good heat dissipation for the miniature refrigeration compressor during operation, ensuring stable operation, extending its service life, and thus ensuring the continuous and reliable refrigeration function of the transport box. The buffer pad installed at the bottom of the miniature refrigeration compressor reduces vibration and noise generated during compressor operation, avoiding unnecessary impact on the kidney donor inside the transport box, and also reducing the wear and tear on the equipment itself.

[0028] In some specific implementations, the air guide 132 is U-shaped, with grooves on its inner wall. A temperature sensor 134 and a Bluetooth transmission module are installed on the inner wall of these grooves. A controller is installed on the inner wall of the control area, and the controller is electrically connected to the temperature sensor 134, the miniature refrigeration compressor, and the Bluetooth transmission module. The U-shaped air guide 132 design guides the cold air generated by the refrigeration component 130 to flow evenly within the refrigeration zone, preventing uneven temperature distribution and ensuring a stable low-temperature environment for all parts of the donor kidney, thus better preserving its viability. Through the Bluetooth transmission module, medical personnel can remotely obtain temperature data from the refrigeration zone, allowing them to monitor the donor kidney's preservation environment even when not physically present, facilitating subsequent operations and decision-making.

[0029] In some specific implementations, the lifting assembly includes an electric push rod 141. The electric push rod 141 is fixedly installed at the bottom of the inner wall of the control area. The output end of the electric push rod 141 passes through the partition 112 and the flow guide 132 and is fixedly connected to the bottom of the storage box 140. The electric push rod 141 is electrically connected to the controller and is located at the center of the control area. Electrical connection to the controller enables precise control of the electric push rod 141, allowing for flexible adjustment of the height of the storage box 140 according to actual needs, meeting the usage requirements of different scenarios.

[0030] In some specific implementation schemes, the sealing cap 120 has symmetrical grooves on both sides, and a sealing ring 121 is fixedly installed at the bottom of the sealing cap 120. The top of the housing 110 has an annular groove that matches the sealing ring 121, and a magnetic ring is fixedly installed at the bottom of the sealing ring 121. An iron ring piece matching the magnetic ring is located at the bottom of the inner wall of the annular groove. The symmetrical grooves on both sides of the sealing cap 120 facilitate the opening and closing of the sealing cap by medical personnel, improving operational convenience. The sealing ring 121 at the bottom of the sealing cap 120 fits tightly with the annular groove at the top of the housing 110, effectively preventing outside air from entering the cold storage area, reducing heat exchange, maintaining a stable low-temperature environment within the cold storage area, and ensuring the preservation effect of the kidney. The magnetic ring at the bottom of the sealing ring 121 attracts the iron ring piece at the bottom of the inner wall of the annular groove, further enhancing the sealing effect. Even if bumps or vibrations occur during transportation, the sealing cap can be kept tightly fitted to the housing, preventing cold air leakage.

[0031] In some specific implementations, sliders 142 are symmetrically fixedly installed on both sides of the storage box 140. The sliders 142 are T-shaped, and symmetrical grooves matching the sliders 142 are provided on the inner wall of the refrigeration compartment. The T-shaped sliders 142 cooperate with the grooves on the inner wall of the refrigeration compartment, making the storage box 140 more stable during sliding, less prone to displacement or shaking, ensuring the safety of the donor kidney within the storage box 140, and preventing damage to the donor kidney due to instability of the storage box 140. This design facilitates the installation and disassembly of the storage box 140, makes cleaning and maintenance of the refrigeration compartment easier, and maintains a hygienic environment for the donor kidney storage.

[0032] In some specific implementation schemes, a dust-free box 143 is slidably installed on the inner wall of the storage box 140, and a support ring 144 is fixedly installed on the top of the dust-free box 143. Handles 145 are symmetrically fixedly installed on the top of the support ring 144. The dust-free box 143 effectively prevents dust and other impurities from contacting the donor kidney, providing a cleaner storage environment, reducing the risk of contamination, and helping to maintain the quality of the donor kidney. The handles 145 at the top of the support ring 144 allow for easy removal or placement of the dust-free box 143 from the storage box 140, facilitating examination and treatment of the donor kidney by medical personnel and improving work efficiency.

[0033] Please refer to Figure 5. A protective frame 150 is fixedly installed on the bottom outer side of the box 110. Buffer springs 151 are symmetrically fixedly installed on all four sides of the protective frame 150. A baffle 152 is fixedly installed at one end of each spring 151, and guide rods 153 are symmetrically fixedly installed on one side of each baffle 152. The protective frame 150 has round holes that match the guide rods 153. Buffer frames, made of rubber, are installed on all four sides of the protective frame 150. These rubber buffer frames on all four sides of the protective frame 150 further enhance the shock absorption capacity of the transport box, providing comprehensive protection for the donor kidney and reducing the risk of damage during transport.

[0034] Working principle: The operator holds the handle 111 and uses the pulleys installed at the four corners of the bottom of the box 110 to easily move the transfer box, which facilitates the rapid transport of organs between different locations.

[0035] For refrigeration and temperature control, battery pack 131 powers the refrigeration component 130 (miniature refrigeration compressor), which then activates refrigeration. The cold air generated by refrigeration enters the refrigeration zone through its output end and channels on partition 112. The air guide 132 is U-shaped, and its top-side air inlets 133 ensure even distribution of cold air into the refrigeration zone, maintaining the organs within the cleanroom box 143 at low temperatures. Temperature sensor 134 monitors the temperature within the refrigeration zone in real time and transmits the data to the controller via Bluetooth. When the temperature exceeds the set value, the controller controls the miniature refrigeration compressor to increase its refrigeration power; when the temperature falls below the set value, the controller controls the miniature refrigeration compressor to reduce its power or stop operating to maintain a stable low-temperature environment within the refrigeration zone.

[0036] When organs need to be retrieved or placed, the dust-free box 143 can be removed by opening the sealing cover 120 and using the handle 145.

[0037] Meanwhile, during kidney repair surgery, the electric push rod 141 is controlled by the controller. The output end of the electric push rod 141 extends or retracts, causing the storage box 140 to rise, raising it to a temporary operating table for convenient surgery. Alternatively, a sterile sheet can be laid on a table, and a dust-free box 143 (containing the kidney) can be placed on it and sterile ice cubes can be added. Then, the kidney repair surgery can be performed.

[0038] The protective frame 150, buffer spring 151, baffle 152, and guide rod 153 at the bottom outer side of the housing 110 form a buffer protection structure. When the transport box is impacted, the baffle 152 compresses the buffer spring 151, causing the spring to deform and absorb the impact force. The guide rod 153 slides within the circular hole of the protective frame 150, ensuring the smooth movement of the baffle 152 and preventing the transport box from being subjected to severe impact, thus protecting the internal organs and equipment. The rubber buffer frames on all four sides of the protective frame 150 also play a role in buffering and shock absorption.

[0039] Internal storage: A cleanroom box 143 is slidably installed inside the storage box 140, allowing organs to be placed inside to reduce contamination from dust and other impurities. The cleanroom box 143 can be easily removed or placed in using the handle 145 at the top of the support ring 144.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
