Description

Technical Field

[0001] This invention relates to the field of placental refrigeration technology, and in particular to a device for refrigerating pregnant placenta. Background Technology

[0002] The umbilical cord and placenta are important organs for the exchange of substances between the fetus and the mother. They are organs formed by the fusion of embryonic membranes and the endometrium of the mother during human pregnancy. Research in the last ten years or so has found that the umbilical cord and placenta contain a variety of stem cells, which can be used for transplantation interventions for diseases of eight major systems or as traditional Chinese medicine.

[0003] After the umbilical cord and placenta are collected, they need to be transferred from the hospital to a liquid nitrogen tank or ultra-low temperature freezer in a storage facility for preservation, so that the placenta can be processed in the following ways: (1) the information collected from the umbilical cord and placenta can be used for pathological research; (2) the placenta can be taken back by the mother's family and eaten or buried by the mother; (3) the placenta can be washed with water and dried naturally, then ground into powder for oral administration; (4) it can be handed over to a professional institution for processing, and hematopoietic stem cells and placental biological factors can be extracted for the treatment of some congenital heart disease, blood system diseases and congenital immune system diseases, such as lupus erythematosus. Regardless of the processing method, the information of the umbilical cord and placenta needs to be recorded.

[0004] Because the refrigeration unit can hold multiple placentas, it needs to be opened and searched when a placenta is removed. This causes the opening time of the refrigeration unit to be unstable, affecting the temperature of the space inside. At the same time, the frequent opening and closing of the refrigeration unit (removing and putting in the items to be preserved) will cause the temperature of the space inside to be unstable.

[0005] Therefore, it is necessary to invent a device for refrigerating the placenta to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a placental refrigeration device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a placental refrigeration device, comprising a plurality of storage units configured to be stacked on top of each other; Each of the storage units includes a rotating frame, and each of the rotating frames is configured to have multiple independent storage cavities for storing storage racks; The rotating frame is equipped with a control device for sequentially exposing the storage cavities of the rotating frame outside the housing; The control device includes selection components corresponding to each target for selection, and a drive device corresponding to each selection component, the drive device being configured to drive the selected target to the retrieval window after the target is selected.

[0008] Optionally, the selected component is a rod-shaped structure that moves vertically relative to the rotating frame, and the rotating frame is provided with a limiting ring for limiting the circumferential position of the rod-shaped structure; The top of the rotating frame is provided with an adjustment frame that can rotate relative to the rotating frame and the selection component, and the adjustment frame extends downward into the interior of the rotating frame; The storage cavity contains a storage rack, which extends towards the center to the inner drive adjustment rack of the rotating frame for rotation.

[0009] Optionally, the adjusting frame includes a sealing cover fixed to the top of the uppermost rotating frame and a first coil spring. The bottom of the sealing cover is provided with an adjusting column that can rotate relative to the sealing cover. When the adjusting column rotates, it drives the first coil spring to store force. A rotating disk is fixedly installed on the upper outer side of the adjusting column. The rotating disk has multiple limiting through holes arranged in a ring array and corresponding one-to-one with the rod-shaped structure. When any limiting rod is pressed down, a force is applied to the inner wall of the limiting through hole, causing the rotating disk to drive the adjusting column to rotate. The outer side of the adjusting column is provided with multiple independent mounting grooves for installing driving components.

[0010] Optionally, the driving component includes an arc-shaped guide frame, a sliding plate, multiple gear teeth, and a first compression spring. The arc-shaped guide frame is fixed inside the mounting groove, and the sliding plate is slidably sleeved on the outside of the arc-shaped guide frame. The multiple gear teeth are arranged in a ring on the outside of the sliding plate. When the placement box is pushed into the storage cavity, it pushes the sliding plate to rotate counterclockwise along the arc-shaped guide frame and compresses the first compression spring. When the gear teeth are misaligned with the placement box, the first compression spring will drive the sliding plate to reset and restrict the placement box. The first compression spring is sleeved on the outside of the arc-shaped guide frame, and its two ends are in contact with the inner wall of the sliding plate and the mounting groove, respectively.

[0011] Optionally, the bottom of the gear teeth in the clockwise direction is set as an arc-shaped part, and the intersection of the arc-shaped part and the gear teeth is the center of the circle, forming a structure that pushes multiple gear teeth to rotate when the placement box is pulled out, so as to allow the placement box to be pulled out normally without affecting the position of the adjustment column.

[0012] Optionally, the storage rack includes a box body, a rubber pad, a gear plate, and a handle. The box body is removable and placed inside the storage cavity, and the opening of the box body is sealed after insertion. The rubber pad is bonded to the outside of the box body and is squeezed after the box body is pulled in. The gear plate is fixed to the rear side of the box body and extends into the interior of the rotating frame to mesh with the gear teeth. During the process of pulling the box body out, the gear teeth and the sliding plate are adjusted. The handle is located on the front side of the box body.

[0013] Optionally, the rod-shaped structure includes a lifting rod, a pressing head, a second compression spring, a truncated cone, and a force-receiving head. The lifting rod is located on the outside of the sealing cover and passes downward through the rotating disk and multiple limiting rings to the interior of the lowest rotating frame. The force-receiving head is fixed to the bottom of the lifting rod and, when the lifting rod is pressed down, drives the force-receiving head to correspond with the driving device. After the driving device is started, the lifting rod drives the corresponding box to rotate to the window. The pressing head is fixed to the top of the lifting rod. The second compression spring is sleeved on the outside of the lifting rod, and its two ends are fixedly connected to the pressing head and the sealing cover, respectively. When the pressing head is pressed down, it compresses the second compression spring. The truncated cone is fixed on the outside of the lifting rod, and the size of the truncated cone increases sequentially from bottom to top, forming a truncated cone that compresses the inner wall of the limiting through hole when it descends, driving the rotating disk to rotate and moving the truncated cone below the rotating disk. After passing through, the rotating disk resets and limits the truncated cone.

[0014] Optionally, the drive device includes a main shaft, a rotating disk, and a pushing protrusion. The main shaft is fixed to the output end of the motor and extends to the center of the rotating frame. The rotating disk is fixed to the top of the main shaft. The pushing protrusion is fixed to the outside of the rotating disk and drives the pushing protrusion of the corresponding height to rotate to the window when the rotating disk rotates.

[0015] Optionally, it also includes a base, a second coil spring, a housing, and a support ring; the base is placed flat on the ground, the housing is fixed to the outside of the base and encloses multiple rotating frames inside, the L-shaped ring plate is fixed to the bottom of the lowest rotating frame, and the two ends of the second coil spring are fixedly connected to the L-shaped ring plate and the housing, respectively.

[0016] Optionally, the interior of the outer shell is fixedly equipped with multiple dividing rings that correspond one-to-one with the rotating frame. The dividing rings are located in contact with the lower surface of the rotating frame and transport the internal cold air into the interior of the box.

[0017] The technical effects and advantages of this invention are as follows: 1. This invention allows for the rapid selection of the appropriate box to be opened by pressing down the lifting rod, while other boxes remain sealed. This reduces the loss of cold air during the removal and placement of boxes, preventing unstable internal temperatures in other boxes from affecting the refrigeration of the placenta.

[0018] 2. This invention rotates the corresponding box to the window by pressing the corresponding lifting rod, which facilitates the quick retrieval and removal of the placenta, saving the time required for placenta placement and removal. At the same time, after the box is pushed back, the lifting rod will be released from its restriction, allowing the box to rotate to the corresponding position for easy retrieval next time. This also eliminates the need for the user to press the rod again, avoiding the impact of the user forgetting to press it. Attached Figure Description

[0021] 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, and 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.

[0022] This invention provides, for example Figure 1-8A placental refrigeration device for pregnancy is shown, comprising multiple storage units configured to be stacked on top of each other. Each storage unit includes a rotating frame 3, and each rotating frame 3 is configured to have multiple independent storage cavities 4 for storing storage racks; The rotating frame 3 is equipped with a control device for sequentially exposing the storage cavities of the rotating frame 3 outside the housing; The control device includes a selection component corresponding to each target for selecting a target to be retrieved, and a drive device corresponding to each selection component. The drive device is configured to drive the selected target to the retrieval window after the target is selected. Each selectable component is a rod-shaped structure that moves vertically relative to the rotating frame 3. The rotating frame 3 is provided with a limiting ring 11 for limiting the circumferential position of the rod-shaped structure. The top of the rotating frame 3 is provided with an adjustment frame that can rotate relative to the rotating frame 3 and the selection component, and the adjustment frame extends downward into the interior of the rotating frame 3; The storage chamber contains a storage rack, which extends towards the center to rotate the inner drive adjustment rack of the rotating frame 3.

[0023] In this embodiment, the rotating frame 3 is divided into multiple independent spaces by the storage cavity 4, so that the storage and retrieval of the corresponding placenta will not affect each other. At the same time, the storage list or placenta that only needs to be temporarily stored can be placed inside the storage cavity 4 corresponding to the window. By rotating the rotating frame 3, the storage cavity 4 can be aligned with the window in sequence, so that the placenta can be properly placed and removed from the storage cavity 4. The limiting ring 11 can limit the rotation frame 3 and the rod structure, so that the rod structure can drive the rotation frame 3 to rotate synchronously when it is subjected to force.

[0024] In some embodiments of the present invention, reference is made to... Figure 2 The adjustment frame includes a sealing cover 6 fixed to the top of the uppermost rotating frame 3 and a first coil spring 7. The bottom of the sealing cover 4 is provided with an adjustment column 5 that can rotate relative to the sealing cover 6. When the adjustment column 5 rotates, it drives the first coil spring 7 to store force. A rotating disk 8 is fixedly installed on the upper outer side of the adjustment column 5. The rotating disk 8 has multiple limit through holes 9 arranged in a ring array and corresponding one-to-one with the rod-shaped structure. When any limit rod is pressed down, a force is applied to the inner wall of the limit through hole 9, causing the rotating disk 8 to drive the adjustment column 5 to rotate. The outer side of the adjustment column 5 is provided with multiple independent mounting grooves 10 for mounting the driving component.

[0025] In this embodiment, the sealing cover 6 limits and guides the up and down movement of the rod-shaped structure; the first coil spring 7 drives the rotating disk 8 to quickly reset after the rotational force on the rotating disk 8 disappears, so that the rotating disk 8 limits the rod-shaped structure after rotation; the force rotation of the rotating disk 8 drives the adjusting column 5 to rotate, so that the adjusting column 5 can normally drive the coil spring 7 to store force. The limiting through hole 9 allows the rod-shaped structure to pass through normally, while the rotating disk 8 can properly restrict the position of the rod-shaped structure; the mounting groove 10 provides space for the installation of the drive component, allowing the drive component to be properly adjusted inside the mounting groove 10.

[0026] In some embodiments of the present invention, reference is made to... Figure 5 and Figure 6 The driving component includes an arc-shaped guide frame 12, a sliding plate 13, multiple gear teeth 14, and a first compression spring 15. The arc-shaped guide frame 12 is fixed inside the mounting groove 10. The sliding plate 13 is slidably sleeved on the outside of the arc-shaped guide frame 12. The multiple gear teeth 14 are arranged in a ring on the outside of the sliding plate 13. When the placement box is pushed into the storage cavity, it pushes the sliding plate 13 to rotate counterclockwise along the arc-shaped guide frame 12 and squeezes the first compression spring 15. When the gear teeth 14 are misaligned with the placement box, the first compression spring 15 will drive the sliding plate 13 to reset and restrict the placement box. The first compression spring 15 is sleeved on the outside of the arc-shaped guide frame 12, and its two ends are in contact with the sliding plate 13 and the inner wall of the mounting groove 10, respectively. The bottom of the gear teeth 14 in the clockwise direction is set as an arc-shaped part 2, and the intersection of the arc-shaped part 2 and the gear teeth 14 is the center of the circle. This forms a structure that pushes multiple gear teeth 14 to rotate when the placement box is pulled out, thereby affecting the position of the adjustment column 5 and allowing the placement box to be pulled out normally.

[0027] In this embodiment, the arc-shaped guide frame 12 serves as a guide for the sliding plate 13, preventing the sliding plate 13 from becoming misaligned during sliding and affecting the normal driving process later. The sliding plate 13 drives the gear teeth 14 to rotate and adjust their position when subjected to force, so that the gear teeth 14 will not affect the normal loading and unloading of the storage rack under certain conditions, ensuring the normal use of the storage rack and not affecting the use of other storage racks. By setting the gear teeth 14, the storage rack is pushed into the later stage, which drives the adjustment column 5 to rotate, so that the rotating disk 8 can release the restriction on the rod structure, and the rod structure can drive the rotating frame 3 to rotate and reset normally. The first compression spring 15 provides space for the sliding plate 13 to slide by compression. At the same time, after the sliding plate 13 slides, the first compression spring 15 stores force. After the driving force on the sliding plate 13 disappears, it can drive the sliding plate 13 to quickly reset, ensuring the normal movement of the sliding plate 13 next time. At the same time, the storage rack can only be taken out normally after the force on it reaches a certain level, which increases the stability of the storage rack. The arc-shaped part 2 provides conditions for the rotation of the gear teeth 14, allowing the gear teeth 14 to release the restriction on the storage rack through rotation. At the same time, a coil spring can be set between the gear teeth 14 and the sliding plate 13 to increase the external force required for the rotation of the gear teeth 14. Meanwhile, the gap between each two adjacent gear teeth 14 is limited, which restricts the rotation angle of the gear teeth 14.

[0028] In some embodiments of the present invention, reference is made to... Figure 7 and Figure 2 The storage rack includes a box body 16, a rubber pad 17, a gear plate 18, and a handle 19. The box body 16 can be pulled out and placed inside the storage cavity 4, and the opening of the box body 16 is sealed after insertion. The rubber pad 17 is bonded to the outside of the box body 16 and is squeezed after the box body 16 is pulled in. The gear plate 18 is fixed to the rear side of the box body 16 and extends into the interior of the rotating frame 3 to mesh with the gear teeth 14. During the process of pulling out the box body 16, the gear teeth 14 and the sliding plate 13 are driven to adjust. The handle 19 is located on the front side of the box body 16.

[0029] In this embodiment, the placement of the placenta is ensured by the setting of the box body 16, and sufficient external force is applied to the box body 16 with the cooperation of the handle 19 so that the box body 16 can be pulled normally and can be taken out and put in normally. The rubber pad 17 can wrap the box 16, so that the box 16 can be properly sealed inside the storage cavity 4. At the same time, it should be compressed so that the box 16 can be pushed a distance further after insertion, so that the gear teeth 14 and the gear plate 18 can be misaligned. The gear plate 18 allows the box 16 to be pushed in or pulled out, which in turn drives the teeth 14 of the gear, making the movement of the box 16 synchronize with the rotation of the rotating frame 3.

[0030] In some embodiments of the present invention, reference is made to... Figure 2The rod-shaped structure includes a lifting rod 20, a pressing head 21, a second compression spring 22, a frustum 23, and a force-receiving head 24. The lifting rod 20 is located on the outside of the sealing cover 6 and extends downward through the rotating disk 8 and multiple limiting rings 11 to the interior of the lowest rotating frame 3. The force-receiving head 24 is fixed to the bottom of the lifting rod 20 and, when the lifting rod 20 is pressed down, drives the force-receiving head 24 to correspond with the driving device. After the driving device is started, the lifting rod 20 drives the corresponding box 16 to rotate to the window position. The pressing head 21 is fixed. The second compression spring 22 is sleeved on the outside of the lifting rod 20 and its two ends are fixedly connected to the pressing head 21 and the sealing cover 6 respectively. When the pressing head 21 presses down, it squeezes the second compression spring 22. The truncated cone 23 is fixed on the outside of the lifting rod 20, and the truncated cone 23 increases from bottom to top. When the truncated cone 23 descends, it squeezes the inner wall of the limiting through hole 9, driving the rotating disk 8 to rotate, so that the truncated cone 23 moves below the rotating disk 8. After passing, the rotating disk 8 resets and limits the truncated cone 23.

[0031] In this embodiment, the corresponding box 16 that needs to be opened is quickly selected by pressing down the lifting rod 20, while other boxes 16 remain sealed, reducing the cold air lost when taking out and putting in the box 16, and avoiding the unstable internal temperature of other boxes 16, which would affect the refrigeration of the placenta. Pressing the corresponding lifting lever 20 rotates the corresponding box 16 to the window, facilitating quick retrieval and removal of the placenta, saving time required for placenta placement and removal. When the box 16 is pushed back, the lifting lever 20 is released from its restriction, allowing the box 16 to rotate to the corresponding position for easy retrieval next time. This eliminates the need for the user to press the lever again, avoiding the impact of the user forgetting to press it. The setting of the pressing head 21 enables external force to press down the lifting rod 20 normally, causing the lifting rod 20 to drive the force receiving head 24 to descend, and squeezing the second compression spring 22 during the pressing down, so that the second compression spring 22 is compressed synchronously. After the limiting force and pressure on the lifting rod 20 disappear, the lifting rod 20 is driven to rise, and the force receiving head 24 is driven to reset. The force-bearing head 24 descends in accordance with the driving device, and under the drive of the driving device, the rotating frame 3 rotates at a corresponding angle, so that the corresponding box 16 rotates to the window. The truncated cone 23 presses against the inner wall of the limiting through hole 9 during descent, causing the rotating disk 8 to drive the adjusting column 5 to rotate. At the same time, the upper part of the truncated cone 23 is flat, and after the truncated cone 23 passes the limiting through hole 9, it will be limited by the rotating disk 8, so that the rotating disk 8 restricts the height of the truncated cone 23 and the lifting rod 20.

[0032] In some embodiments of the present invention, reference is made to... Figure 2The drive device includes a main shaft 25, a rotating disk 26, and a push protrusion 27. The main shaft 25 is fixed at the output end of the motor and extends to the center of the rotating frame 3. The rotating disk 26 is fixed at the top of the main shaft 25. The push protrusion 27 is fixed on the outside of the rotating disk 26 and drives the push protrusion 27 to rotate to the window when the rotating disk 26 rotates.

[0033] In this embodiment, the main shaft 25 is fixedly connected to the output end of the motor, and the main shaft 25 rotates one revolution each time it is driven. The rotating disk 26 makes the main shaft 25 and the pushing protrusion 27 rotate synchronously. By pushing the protrusion 27 to contact the force-bearing head 24 during rotation, the lifting rod 20 and the rotating frame 3 are driven to rotate synchronously by a certain angle under the action of the force-bearing head 24.

[0034] In some embodiments of the present invention, reference is made to... Figure 3 It also includes a base 28, a second coil spring 29, a housing 30, and a support ring 31; the base 28 is placed flat on the ground, the housing 30 is fixed to the outside of the base 28 and encloses multiple rotating frames 3 inside, the L-shaped ring plate 31 is fixed to the bottom of the lowest rotating frame 3, and the two ends of the second coil spring 29 are fixedly connected to the L-shaped ring plate 31 and the housing 30 respectively. Multiple dividing rings 32, corresponding one-to-one with the rotating frame 3, are fixedly installed inside the outer shell 30. The dividing rings 32 are located on the lower surface of the rotating frame 3 and are in contact with it, transporting the internal cold air to the inside of the box 16.

[0035] In this embodiment, the base 28 ensures the placement and fixation of the device; at the same time, the rotating frame 3 is wrapped with the outer shell 30 and the rotation of the rotating frame 3 is limited, while the storage cavity 4 on the rotating frame 3 is sealed. The second coil spring 29 is installed to drive the rotating frame 3 to reset after the rotating frame 3 rotates, so that the rotating frame 3 can determine its position next time and avoid the position being confused. The rotating frame 3 is supported by the support ring 31, and at the same time the force of the second coil spring 29 can be applied to the rotating frame 3 normally. The multiple rotating frames 3 are divided by the dividing ring 32. At the same time, the dividing ring 32 is equipped with air guide pipes. The multiple air guide pipes are not connected to each other and do not affect each other. The cold zone is transported to the bottom of the box 16 and enters through the opening at the bottom of the box 16. At the same time, the part corresponding to the window does not need to be provided with an opening.

[0036] The working method of this invention: When in use, determine the corresponding placenta placement position as needed, and then press the corresponding pressing head 21 according to the placenta position. The pressing head 21 drives the lifting rod 20 to descend, and drives the truncated cone 23 and the force-bearing head 24 to descend synchronously. When the pressing head 21 descends, it will also squeeze the second compression spring 22. When the truncated cone 23 descends, it will press against the inner wall of the limiting through hole 9, causing the rotating disk 8 to rotate under the pressure, and driving the adjusting column 5 to rotate synchronously. At the same time, the first coil spring 7 will store force. Meanwhile, due to the restriction of the gear plate 18, the gear teeth 14 will rotate relative to the adjusting column 5 to ensure the normal rotation of the adjusting column 5. When the truncated cone 23 passes the limiting through hole 9, the first coil spring 7 will drive the adjusting column 5 and the rotating disk 8 to reset and restrict the truncated cone 23. At the same time, the force-bearing head 24 will descend to the same height as the pushing protrusion 27. Then start the motor, so that the motor drives the rotating disk 26 and the pushing protrusion 27 to rotate one revolution. During the rotation, the pushing protrusion 27 contacts the force receiving head 24, and pushes the force receiving head 24 and the lifting rod 20 to rotate synchronously. During the rotation, the motor squeezes the inner wall of the limiting through hole 9 and the limiting ring 11, so that the rotating disk 8 drives the adjusting column 5 to rotate synchronously, and the limiting ring 11 drives the rotating frame 3 and the sealing cover 6 to rotate synchronously. The rotating frame 3 drives the corresponding box 16 to move to the opening. When the rotating frame 3 rotates, the second coil spring 29 stores power as the supporting ring 31 rotates. Pull the box 16 to move it out of the storage cavity 4. As the box 16 moves, the sliding plate 13 rotates along the arc-shaped guide frame 12 under the action of the gear teeth 14. When it contacts the inner wall of the mounting groove 10, the gear teeth 14 start to rotate, so that the gear plate 18 passes over the gear teeth 14 normally, allowing the box 16 to be moved out of the storage cavity 4. Then, the placenta is taken out or the placenta is put into the inside of the box 16. After the placenta is removed or placed into the box 16, the box 16 is pushed into the storage cavity 4. During this process, the gear plate 18 pushes the gear teeth 14, causing the gear teeth 14 to rotate the sliding plate 13 along the arc-shaped guide frame 12. This causes the arc-shaped guide frame 12 to compress the first compression spring 15. When the first compression spring 15 is compressed to its limit, the adjusting column 5 and the sliding plate 13 are pushed to rotate synchronously. During this process, the box 16 is also pushed to compress the rubber pad 17. When the adjusting column 5 rotates, it causes the rotating disk 8 to rotate in the opposite direction, aligning the center of the limiting through hole 9 with the center of the lifting rod 20. The first compression spring 15 then causes the lifting rod 20 to rise, which in turn causes the truncated cone 23 and the force-bearing head 24 to rise. This causes the gear teeth 14 and the gear plate 18 to become misaligned. The sliding plate 13 then quickly resets under the action of the first compression spring 15. The rubber pad 17 then causes the box 16 to reset, and finally, the second coil spring 29 causes the rotating frame 3 to rotate and reset.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

The multiple gear teeth are arranged in a ring on the outside of the sliding plate. When the placement box is pushed into the storage cavity, it pushes the sliding plate to rotate counterclockwise along the arc-shaped guide frame and compresses the first compression spring. When the gear teeth are misaligned with the placement box, the first compression spring will drive the sliding plate to reset and restrict the placement box. The first compression spring is sleeved on the outside of the arc-shaped guide frame, and its two ends are in contact with the inner wall of the sliding plate and the mounting groove, respectively.

5. The placental refrigeration device according to claim 4, characterized in that: The bottom of the gear teeth in the clockwise direction is set as an arc-shaped part, and the intersection of the arc-shaped part and the gear teeth is the center of the circle. This forms a structure that pushes multiple gear teeth to rotate when the placement box is pulled out, so as to allow the placement box to be pulled out normally without affecting the position of the adjustment column.

6. The placental refrigeration device according to claim 1, characterized in that: The storage rack includes a box body, a rubber pad, a gear plate, and a handle. The box body is removable and placed inside the storage cavity, and the opening of the box body is sealed after insertion. The rubber pad is bonded to the outside of the box body and is squeezed after the box body is pulled in. The gear plate is fixed to the rear side of the box body and extends into the interior of the rotating frame to mesh with the gear teeth. During the process of pulling the box body out, the gear teeth and the sliding plate are adjusted. The handle is located on the front side of the box body.

7. The placental refrigeration device according to claim 1, characterized in that: The rod-shaped structure includes a lifting rod, a pressing head, a second compression spring, a truncated cone, and a force-receiving head. The lifting rod is located on the outside of the sealing cover and passes downward through the rotating disk and multiple limiting rings to the interior of the lowest rotating frame. The force-receiving head is fixed to the bottom of the lifting rod and, when the lifting rod is pressed down, drives the force-receiving head to correspond with the driving device. After the driving device is started, the lifting rod drives the corresponding box to rotate to the window. The pressing head is fixed to the top of the lifting rod. The second compression spring is sleeved on the outside of the lifting rod, and its two ends are fixedly connected to the pressing head and the sealing cover, respectively. When the pressing head is pressed down, it compresses the second compression spring. The truncated cone is fixed on the outside of the lifting rod, and the size of the truncated cone increases sequentially from bottom to top, forming a truncated cone that compresses the inner wall of the limiting through hole when it descends, driving the rotating disk to rotate and move the truncated cone below the rotating disk. After passing through, the rotating disk resets and limits the truncated cone.

8. The placental refrigeration device according to claim 1, characterized in that: The drive device includes a main shaft, a rotating disk, and a pushing protrusion. The main shaft is fixed at the output end of the motor and extends to the center of the rotating frame. The rotating disk is fixed at the top of the main shaft. The pushing protrusion is fixed on the outside of the rotating disk and drives the pushing protrusion to rotate to the window at a corresponding height when the rotating disk rotates.
