[0002] Liver disease treatment is a series of medical measures taken for liver diseases caused by various reasons. For some liver diseases that require surgical intervention, such as liver cancer and liver abscess, surgical treatment may be required. Surgical treatment can treat the disease by removing diseased tissue, repairing liver damage, and transplanting the liver.

[0003] The liver transplantation cooling and transport box for liver disease treatment is a medical device that integrates multiple functions such as refrigeration, heat preservation, and shockproof. It is specially used for the preservation and transportation of the liver during liver transplantation. It maintains a low temperature environment (usually 0°C to 4°C) inside the box through a built-in refrigeration mechanism and temperature control system to inhibit the decomposition rate of liver cells, prolong the storage period of the liver, and reduce damage caused by temperature changes. Because it has the advantages of prolonging the storage period of the liver, reducing liver damage and facilitating transportation, it is widely used in the field of liver transplantation transportation.

[0004] In the "A liver transplantation liver cooling transport box" with the patent CN116530504A, it includes a box body, a balancing component, a first cover plate, a second cover plate, a driving component and a clamping component. A barrel groove is opened inside the box body, a cooling device is arranged inside the barrel groove, an opening is opened at the top of the box body, a first cover plate and a second cover plate are hinged on both sides of the opening, two clamping components are arranged at the bottom of the first cover plate and the second cover plate, the two clamping components are connected to the driving components inside the two cover plates, a balancing component is arranged inside the barrel groove, a liver source is placed inside the balancing component and immersed in a protective liquid, the cooling device cools the inside of the barrel groove, and when the box body tilts, the balancing component keeps the liver source balanced to prevent the liver source from being damaged due to the tilt of the box body;

[0005] In the "A Uniformly Temperature-Controlled Movable Liver Transport Box" with the patent publication CN112833602A, it includes: a transport box with a refrigeration module, the refrigeration module is used to refrigerate the liver carried by the transport box; a transport module installed on the transport box, the transport module drives the transport box to move; a telescopic motion module, the telescopic motion module is installed in the transport box, the telescopic motion module can drive the liver to move and be cooled evenly; and a control module and a power module, the control module controls the refrigeration power of the refrigeration module, the telescopic stroke and frequency of the telescopic motion module. The beneficial effects are: the uniformly temperature-controlled movable liver transport box is used in the transportation of livers of liver transplant donors, which not only avoids the problem of local freezing of the liver, but also cools the liver evenly, has a simple structure and strong operability; and maintains a slight movement frequency of the liver under low temperature conditions, avoiding the problem of manual repeated turning and massaging of the liver;

[0006] In the patent CN114847273A, a liver transplantation liver cooling and transport box is disclosed, which includes a box body and a cover body hinged on the upper part of the box body, the side wall of the box body is provided with a power box, the inside of the box body is provided with a slip ring, the slip ring is a square frame structure, the upper end of the slip ring is fixedly connected with four soft rubber plates, the cover body at one end of the multiple soft rubber plates away from the slip ring is fixedly connected with a bottom bracket, an arc plate is placed on the upper end of the bottom bracket, the side wall of the box body is rotatably connected with multiple groups of rollers, each group of rollers includes two roller rods, one group of rollers is located on both sides of the soft rubber plate, the lower inner wall of the box body is fixedly connected with a winding wheel, and the slip ring is fixedly connected with a traction rope. The advantages are: the liver to be transplanted is placed on the arc plate in the box body, and the refrigeration device in the refrigeration bin absorbs heat from the heat exchange tube, thereby taking away the heat in the box body, realizing the refrigeration of the liver in the box body, and avoiding liver damage caused by excessive temperature;

[0007] In the existing cooling transfer box, when performing liver transplantation, the inner box is usually placed manually inside the box. When taking out the inner box, it is inconvenient to take it out and place it later because the exposed surface of the inner box is small, which is very time-consuming and laborious. At the same time, the preservation fluid may be contaminated due to manual handling, which is not convenient for the stable transportation and use of the transfer box later.

[0008] Therefore, we propose a liver transplantation cooling transport box for liver disease treatment to solve the above-mentioned problems. Summary of the invention

When the sealing cover is flipped and closed, the placement rack will be lowered by the weight of the inner box. At this time, the two positioning plates can be separated from the two mounting rods by the principle of magnetic field repulsion. Then, the two rows of first squeezing springs will clamp and position the placed inner box through the anti-slip pads by their own elastic force, so as to avoid the inner box from loosening and deviating during the movement and transportation of the box body, thereby improving the placement stability of the inner box.

[0025] (4) A single-rotation reciprocating screw is provided, and the single-rotation reciprocating screw is installed by rotating the single-rotation reciprocating screw through the transmission belt by using the grooves at both ends of the inner body, and then a driving motor is connected to the bottom of the single-rotation reciprocating screw at the left end, and the two single-rotation reciprocating screws can be driven to rotate by the transmission belt while the driving motor rotates. At this time, the refrigeration plates connected by the outer threads of the two single-rotation reciprocating screws will move back and forth at the same time, and then the two refrigeration plates can perform reciprocating refrigeration on both sides of the inner box, thereby avoiding the traditional box refrigeration range being too single, which may cause frostbite of the liver placed in the inner box;

[0026] (5) A limit block is provided, and a positioning belt is provided at the left end of the box, and then the other end of the positioning belt is extended to the outside of the right end of the box. When medical staff need to carry and transport the box, they only need to carry the box on their backs through the positioning belt, and then pull the positioning belt to tighten the box, which saves the physical strength of medical staff.

[0044] The box body 1 has grooves at both ends inside and drive gears 17 are rotatably installed, and the two drive gears 17 are symmetrically arranged about the vertical center line of the box body 1, and the outer ends of the two drive gears 17 extend through and extend to the top sides of the box body 1, the outer sides of the two drive gears 17 are meshed and connected to the placement rack 6 through racks 16, and the two racks 16 are arranged on both sides of the placement rack 6.

[0045] like Figure 1-Figure 5 As shown, when the liver needs to be stored and transported, it is only necessary to manually open the sealing cover 2, and then the pull ropes 5 connected at both ends of the bottom of the sealing cover 2 will simultaneously pull the two driving gears 17 to rotate through the guide wheels, and then the two driving gears 17 will simultaneously drive the placement rack 6 to move upward through the two racks 16, so that the inner box 8 can be quickly placed and positioned, and then the sealing cover 2 can be flipped over to close it, and the inner box 8 can be quickly taken and placed later. At this time, the two driving gears 17 will drive the inner box 8 to move downward through the two racks 16, and the operation is more time-saving and labor-saving.

[0046] Embodiment 2 is different from Embodiment 1 in that the inner box 8 can be automatically clamped and positioned after placement, and the buffering and protective performance of the liver inside the inner box 8 can be improved to prevent the liver from shaking and being damaged due to later movement and transportation. The following is disclosed:

[0047] The top plate 7 has swing rods 13 at both ends of its bottom connected by movable shafts, and the two swing rods 13 are inclined, and the bottoms of the two swing rods 13 are connected to moving blocks 14 through movable shafts, and the two moving blocks 14 are slidably installed on both sides of the bottom of the placement rack 6 through reset springs 15.

[0048] The top plate 7 has mounting rods 20 installed at both ends of its top by screws, and the first magnets 21 are arranged on the outer sides of the tops of the two mounting rods 20, and the outer ends of the two first magnets 21 correspond to the second magnets 22, and the two second magnets 22 are arranged at the bottom of the two positioning plates 9, and the outer sides of the two single-rotation reciprocating screw rods 18 are threadedly penetrated and connected with refrigeration plates 19, and the two refrigeration plates 19 are slidably installed on both sides of the inner wall of the box body 1, and the outer sides of the two refrigeration plates 19 correspond to the two sides of the inner box 8.

[0049] like Figure 1-Figure 8 As shown, after the inner box 8 is placed on the top plate 7 arranged at the bottom of the placement rack 6, the inner box 8 will drive the top plate 7 to be squeezed and lowered through the two damping rods 12. The two damping rods 12 can increase the buffering and protection performance of the liver inside the inner box 8 to prevent the liver from being damaged by collision due to movement and transportation. When the top plate 7 is squeezed and lowered, the two mounting rods 20 will also be driven to lower their positions, so that the first magnet 21 and the second magnet 22 can disappear. Then, the two rows of first squeezing springs 11 will clamp and position the two positioning plates 9 through the anti-slip pads 10 to the position of the inner box 8 after placement through their own elastic force, so as to prevent the inner box 8 from loosening and deviating due to transportation and movement in the later stage, thereby improving the placement stability of the inner box 8.

[0050] After the inner box 8 is stably placed inside the box body 1, the temperature inside the box body 1 is monitored by the temperature control unit. When the temperature inside the box body 1 is monitored to be too high, the temperature control unit will start the drive motor through the signal module to drive the two single-rotation reciprocating screws 18 to rotate through the transmission belt at the same time. At this time, the two single-rotation reciprocating screws 18 will simultaneously drive the two refrigeration plates 19 to move back and forth, so as to increase the refrigeration range of the two refrigeration plates 19, avoid the traditional refrigeration equipment can only be used for cooling the same position, and improve the practicality of the box body 1.

[0051] Embodiment 3 is different from Embodiment 2 in that the box 1 can be carried and transported by means of a positioning belt 4 to save the physical strength of medical staff. It discloses:

[0052] The box body 1 has a second extrusion spring 25 provided in a groove inside the right end thereof, and the outer end of the second extrusion spring 25 is connected to the limiting block 23, and the outer end of the second extrusion spring 25 is connected to the limiting block 23, and the limiting block 23 is rotatably installed inside the right side of the box body 1, the limiting block 23 is in an arc shape, and the outer side of the limiting block 23 is connected in sequence with a row of limiting grooves 24, and the row of limiting grooves 24 are all arranged at equal intervals on the outer side of the positioning belt 4.

[0053] The limit block 23 has a torsion spring 27 slotted inside, and a shaft 26 is wound around the inner side of the torsion spring 27 , and the shaft 26 is rotatably mounted inside the limit block 23 , and the outer end of the shaft 26 extends through to the outside of the box body 1 .

[0054] like Figure 1-Figure 10 As shown, when the medical staff needs to carry and transport the box 1, one end of the positioning belt 4 is extended to the outside of the right end of the box 1. At this time, the second extrusion spring 25 will use its own elastic force to pop out the limit blocks 23 into a row of limit grooves 24 in sequence, and then the pulled positioning belt 4 can be slid and limited to avoid the positioning belt 4 from loosening and falling off during the later stage of carrying and transportation, and the positioning belt 4 can be better tightened to facilitate the medical staff to carry and transport the box 1;

[0055] When it is necessary to pull out and reset the positioning belt 4, it is only necessary to manually rotate the rotating shaft 26 to drive the limit block 23 to separate from the limit groove 24. At this time, the positioning belt 4 can be separated from the box body 1, and then the positioning belt 4 can be pulled out and reset. Finally, the elastic force of the torsion spring 27 can be used to elastically reset the position of the rotating shaft 26 after rotation, so that it can be repeated in the future, thereby completing a series of tasks.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
