Description

Technical Field

[0001] This invention belongs to the field of visceral specimen preservation devices, specifically a human anatomical visceral specimen preservation device. Background Technology

[0002] Human anatomy is the science that studies the morphology, structure, location, adjacency, and structural-functional relationships of various parts of the normal human body. It is divided into gross anatomy and microscopic anatomy. For teaching purposes, visceral specimens are often used for explanation. However, during the storage and transport of visceral specimens, due to the different sizes of the specimens and the fixed capacity of the storage devices, the visceral specimens are easily damaged.

[0003] To address the aforementioned issues, Chinese patent document CN111674724B discloses a device for preserving human anatomical visceral specimens. Its structure includes a preservation box, a reinforcing sealing plate, a top cover, a magnetic strip, a handle, and a controller. The upper end of the reinforcing sealing plate is fixedly connected to the lower end of the top cover. This invention, through the arrangement of a placement rack structure and a storage box structure, uses water to move the wrapping layer towards the visceral specimen, ensuring the buffer layer adheres to the specimen. The water-driven wrapping layer effectively protects the visceral specimen from shaking and impact during transport, thus preventing damage.

[0004] However, it is difficult to control the amount of water injected into the encapsulation layer. If too little water is injected, the encapsulation layer may not be able to fully adhere to the visceral specimen. If too much water is injected, the encapsulation layer may easily compress the visceral specimen, so that the visceral specimen cannot be effectively protected in the preservation device, or may even be damaged due to the compression of the preservation device. Summary of the Invention

[0005] The purpose of this invention is to provide a device for preserving human anatomical visceral specimens, which can effectively wrap and fix the visceral specimens, avoid excessive compression of the visceral specimens, and improve the stability of the viscera in the preservation device during movement.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A human anatomical visceral specimen preservation device includes a box, a plurality of partitions are provided on the inner side wall of the box, the partitions abut against the top wall and bottom wall of the box, a connecting column is fixedly connected to the end of the partition away from the inner side wall of the box, the connecting column is fixedly connected to the bottom of the box, an elastic wrapping layer is connected between adjacent connecting columns, the elastic wrapping layer, the partitions and the inner side wall of the box form a liquid storage chamber, and the elastic wrapping layer surrounds the middle part of the box to form a placement chamber;

[0007] The top wall of the box is hinged with a cover, and the surface of the box has a placement port and a liquid injection hole. The placement port is connected to the placement chamber, and the liquid injection hole is connected to each liquid storage chamber. A refrigeration component is fixedly connected to the side wall of the box. The refrigeration component is connected to each liquid storage chamber through a circulation pipe. A solenoid valve with a passage corresponding to the number of liquid storage chambers is connected to the circulation pipe.

[0008] Each side wall of the liquid storage chamber is fixedly connected to a first strain gauge. The first strain gauge signal is connected to the same controller. The controller is connected to the solenoid valve and the refrigeration component. The controller signal is connected to an indicator component. The controller is used to receive the resistance value change signal of the first strain gauge and control the operation of the indicator component, solenoid valve and refrigeration component according to the resistance value change signal.

[0009] The technical principles of the above solution are as follows:

[0010] The visceral specimen can be placed into the placement chamber inside the box through the placement port. Then, liquid is injected into the storage chamber through the injection port. As the amount of liquid increases, the elastic wrapping layer gradually experiences increased pressure from the liquid, causing it to deform and encapsulate the visceral specimen. At the same time, the water pressure on the first strain gauge also gradually increases. Once the elastic wrapping layer comes into contact with the visceral specimen, it will be difficult for it to deform further, while the water pressure on the first strain gauge will continue to increase. When the water pressure on the first strain gauge reaches a threshold, an alert is issued by the prompting component, thereby stopping the injection of liquid to avoid excessive compression of the visceral specimen by the elastic wrapping layer. At the same time, the elastic wrapping layer will not cause excessive compression of the visceral specimen. In addition, the liquid in the storage chamber can be circulated through the cooling component to maintain the visceral specimen at a suitable temperature.

[0011] During the movement of the carrying device, the internal organs may sway due to the shaking of the container. When the internal organs sway towards a certain liquid storage chamber, the pressure of the internal organs on the elastic wrapping layer in the direction of swaying increases due to the pressure of the water in the corresponding liquid storage chamber on the first strain gauge. This causes the pressure on the first strain gauge to exceed the threshold, and the controller controls the solenoid valve to stop the liquid circulation in the corresponding liquid storage chamber. This allows the elastic wrapping layer of the corresponding liquid storage chamber to have a greater restoring force to buffer the shaking of the internal organs, reduce the shaking of the internal organs in the placement chamber, and make the internal organs more stably protected during the carrying and moving process.

[0012] The above approach has the following beneficial effects:

[0013] 1. This method uses a first strain gauge to detect the liquid pressure in the storage chamber and stops adding liquid when the pressure reaches a threshold. Compared with adding liquid directly without any basis, it is easier to control the amount of liquid added. It can effectively avoid the problem of excessive liquid adding causing compression to the visceral specimen, and the problem of insufficient liquid adding failing to effectively wrap the visceral specimen.

[0014] By circulating and cooling the liquid in the storage chamber, the visceral specimens are preserved at a suitable temperature. Compared to cooling directly in the placement chamber, the elastic wrapping layer adheres to the surface of the visceral specimens, allowing the cooled liquid to directly apply the cooling temperature to the surface of the visceral specimens through heat exchange, thus improving the temperature control effect. At the same time, the storage chamber effectively reduces heat exchange between the visceral specimens and the outside air, thereby avoiding the influence of the outside temperature on the visceral specimens.

[0015] 2. This solution uses the elasticity of the elastic wrapping layer and the buffering force of the liquid storage chamber after the liquid is added to buffer the shaking of the internal organs during the movement of the device. In addition, during the movement of the device, the internal organ specimen squeezes the liquid storage chamber, and the pressure in the liquid storage chamber will increase after being squeezed. That is, the pressure on the corresponding first strain gauge will increase. When the resistance value of the first strain gauge changes beyond the threshold due to the sudden pressure change, the controller controls the solenoid valve to close the liquid cooling cycle in the corresponding liquid storage chamber, so that the liquid storage chamber has a greater buffering force to buffer the shaking of the internal organ specimen.

[0016] Meanwhile, because the liquid in the remaining storage chambers is continuously refrigerated, the pressure on the visceral specimen is less than that in the storage chambers where the refrigeration cycle has stopped. Therefore, it can promote the rapid repositioning of the visceral specimen and improve the stability of the viscera during movement.

[0017] In summary, this method effectively encapsulates and secures visceral specimens, avoiding excessive compression and improving the stability of the viscera within the preservation device during transport.

[0018] Furthermore, a horizontal plate is movably connected to the bottom of the placement chamber, and several spring plates are installed in the gap between the horizontal plate and the placement chamber. A second strain gauge is installed below the spring plates located at the edge. The second strain gauge is connected to the controller signal, and the controller is also used to receive the resistance value change signal of the second strain gauge.

[0019] Beneficial effects: During the movement of the viscera, shaking the horizontal plate in the corresponding direction will cause it to tilt in that direction and contact the spring plate. The spring plate cushions the tilt of the horizontal plate, thereby further improving the stability of the viscera specimen during movement. In the initial stage of placing the viscera specimen into the placement chamber and during movement, if the viscera specimen shakes too much or its position shifts significantly, the second strain gauge will be squeezed by the spring plate. When the second strain gauge is squeezed, the controller will promptly alert the user through the prompting component, allowing the user to adjust the position of the viscera specimen in time and avoid damage to the viscera specimen.

[0020] Furthermore, a protective flange is provided on the edge of the horizontal plate, and the top of the protective flange has an arc-shaped structure.

[0021] Beneficial effect: The protective flange limits the position of the visceral specimen on the horizontal plate, restricting its displacement.

[0022] Furthermore, the refrigeration component includes a housing fixedly connected to the side wall of the enclosure, a refrigeration plate is installed inside the housing, and a water inlet and a water outlet are provided on the side wall of the housing. The water inlet and the water outlet are respectively connected to a circulation pipe, and a circulation pump is connected to the water inlet or the water outlet. The circulation pump is signal connected to the controller.

[0023] Beneficial effects: By using cooling plates to circulate the liquid in each storage chamber, the temperature of the cooled liquid can more directly affect the surface of the visceral specimen.

[0024] Furthermore, the prompting components include a display and a buzzer. The display is fixedly connected to the outer wall of the enclosure, and the buzzer is embedded in the enclosure. Both the display and the buzzer are connected to the controller signal. The display is used to show the water pressure in each liquid storage chamber, and the buzzer is used to sound when the water pressure in the liquid storage chamber exceeds a threshold.

[0025] Beneficial effects: Through the display, users can intuitively observe data such as the pressure inside the liquid storage chamber of the box, and the buzzer will prompt the user, making it easier for the user to accurately control the amount of liquid added to the liquid storage chamber.

[0026] Furthermore, a temperature and humidity sensor is installed in the placement chamber. The temperature and humidity sensor is connected to the controller signal, and the display is also used to display the temperature and humidity data collected by the temperature and humidity sensor.

[0027] Beneficial effects: The temperature and humidity inside the placement chamber are displayed on a monitor for the user to view, making it easy for the user to adjust the temperature and humidity inside the placement chamber.

[0028] Furthermore, a first sealing cover and a second sealing cover are provided on the contact surface between the cover and the top wall of the box, and the positions of the first sealing cover and the second sealing cover correspond to the positions of the injection hole and the placement port, respectively.

[0029] Beneficial effects: The first and second sealing caps prevent convection between the liquid storage chamber and the placement chamber and the outside air, reducing the loss of cold air from the liquid storage chamber and the placement chamber.

[0030] Furthermore, a shut-off solenoid valve is connected inside the injection hole, and the shut-off solenoid valve is connected to the controller signal.

[0031] Beneficial effect: When the water pressure on the first strain gauge exceeds the threshold, the controller's solenoid valve closes to prevent the user from failing to stop the addition of liquid in time, which could cause excessive compression of the visceral specimen.

[0032] Furthermore, the sidewall of the placement opening has a V-shaped cross-section.

[0033] Beneficial effects: The V-shaped placement opening protects the internal organs during insertion and removal, preventing damage to the internal organs.

[0034] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0044] The following detailed description illustrates the specific implementation method:

[0045] The reference numerals in the accompanying drawings include: cover 1, box 2, refrigeration assembly 3, outer shell 31, refrigeration element 32, first strain gauge 4, connecting column 5, elastic wrapping layer 6, display 7, second sealing cover 8, first sealing cover 9, liquid injection hole 10, placement port 11, partition 12, circulation pipe 13, solenoid valve 14, horizontal plate 15, limiting flange 16, spring plate 17, and second strain gauge 18.

[0046] Example 1

[0047] As attached Figure 1 As shown: A device for preserving human anatomical visceral specimens includes a rectangular box 2. Handles are fixedly connected to the left and right side walls of the box 2 for easy carrying. Several partitions 12 are fixedly connected to the inner side wall of the box 2. The partitions 12 abut against the inner top and bottom walls of the box 2. A connecting post 5 is fixedly connected to the end of the partition 12 away from the inner side wall of the box 2. The connecting post 5 is fixedly connected to the bottom of the box 2. An elastic wrapping layer 6 is connected between adjacent connecting posts 5. The elastic wrapping layer 6 can be made of natural rubber film.

[0048] As attached Figure 2 As shown, the elastic wrapping layer 6, the partition 12 and the inner wall of the box 2 form a liquid storage chamber. A drain outlet is provided at the bottom of the liquid storage chamber (not shown in the attached figure). The elastic wrapping layer 6 surrounds the middle part of the box 2 to form a placement chamber. The liquid storage chamber has a trapezoidal structure and the placement chamber has a regular hexagonal structure.

[0049] A rectangular cover 1 is hinged to the top wall of the box 2, which completely covers the top of the box 2. The surface of the box 2 has a placement port 11 and a liquid injection hole 10. The placement port 11 communicates with the placement chamber, and the liquid injection hole 10 communicates with each liquid storage chamber. A first sealing cover 9 and a second sealing cover 8 are fixedly connected to the contact surface between the cover 1 and the top wall of the box 2. The positions of the first sealing cover 9 and the second sealing cover 8 correspond to the positions of the liquid injection hole 10 and the placement port 11, respectively. During the process of closing the cover 1, the liquid injection hole 10 and the placement port 11 can be sealed simultaneously through the first sealing cover 9 and the second sealing cover 8, thereby preventing the exchange of internal and external gases.

[0050] A refrigeration assembly 3 is fixedly connected to the side wall of the housing 2. The refrigeration assembly 3 is connected to each liquid storage chamber through a circulation pipe 13. A solenoid valve 14 with a corresponding number of liquid storage chambers is connected to the circulation pipe 13. In this embodiment, the number of liquid storage chambers is six. Therefore, a six-way solenoid valve 14 can be used, or two three-way solenoid valves 14 can be used to control the liquid circulation in the three liquid storage chambers on the corresponding side.

[0051] As attached Figure 6 As shown, the refrigeration component 3 includes an outer shell 31 fixedly connected to the side wall of the housing 2. The width of the outer shell 31 is the same as the width of the housing 2, which can ensure the circulating water volume while increasing the simplicity of the appearance of the housing 2 for easy carrying. A cooling plate 32 is fixedly connected inside the outer shell 31. Water inlet and water outlet are respectively opened on the upper and lower sides of the side wall of the outer shell 31. The water inlet and water outlet are respectively connected to the circulation pipe 13, and a circulation pump (not shown in the figure) is connected to the water inlet or water outlet. The circulation pump is connected to the controller signal. The operation of the circulation pump can realize the circulation of liquid in the storage chamber. At the same time, the circulation pipe 13 of the corresponding chamber can be opened and closed by the solenoid valve 14 to realize targeted cooling circulation of liquid in a certain part of the water storage chamber.

[0052] As attached Figure 1 As shown, each side wall of the liquid storage chamber is fixedly connected to a first strain gauge 4. The first strain gauge 4 is connected to the same controller. The controller is connected to the solenoid valve 14, the cooling element 32 in the cooling assembly 3, and the circulation pump. The controller receives the resistance value change signal of the first strain gauge 4 and controls the operation of the prompting assembly, the solenoid valve 14, and the cooling assembly 3 according to the resistance value change signal.

[0053] To facilitate users in obtaining the compressive force on the first strain gauge 4 in each water storage chamber, a prompting component is connected via a controller signal. The prompting component includes a display 7 and a buzzer. The display 7 is fixedly connected to the outer wall of the housing 2, and the buzzer is embedded in the housing 2. Both the display 7 and the buzzer are connected to the controller signal. The display 7 displays the water pressure in each liquid storage chamber, and the buzzer is used to sound when the water pressure in the liquid storage chamber exceeds a threshold.

[0054] The side wall of the aforementioned placement port 11 has a V-shaped structure, which can protect the visceral specimen during the process of placing and removing the visceral specimen. Secondly, the injection hole 10 is connected to a shut-off solenoid valve 14, which is connected to the controller signal. When the resistance value change signal of the first strain gauge 4 exceeds the threshold, the shut-off solenoid valve 14 is closed by the controller, thereby preventing liquid from being injected into the storage chamber.

[0055] The specific implementation process is as follows:

[0056] As attached Figure 3As shown, firstly, the cover 1 is opened and the visceral specimen is placed into the placement chamber through the placement port 11. Liquid is injected into each storage chamber through the injection port 10. As the liquid in the storage chamber increases, the elastic wrapping layer 6 gradually deforms and covers the visceral specimen. When the elastic wrapping layer 6 comes into contact with the visceral specimen, as liquid continues to be added to the storage chamber, the compression on the first strain gauge 4 will continue to increase. When the resistance value change signal caused by the compression of the first strain gauge 4 exceeds the threshold, the shut-off solenoid valve 14 closes, so that liquid can no longer be added through the injection port 10. This ensures that the elastic wrapping layer 6 neither over-compresses the visceral specimen nor fails to effectively wrap the visceral specimen.

[0057] Subsequently, the liquid in the storage chamber is transported to the outer shell 31 by a circulation pump, where it comes into contact with the cooling chip 32 and is cooled before being transported back to the storage chamber. The cooled liquid then comes into contact with the elastic wrapping layer 6, which in turn comes into contact with the visceral specimen, thereby maintaining the temperature of the visceral specimen.

[0058] During the movement of the device, when the visceral specimen shakes to one side and compresses the elastic wrapping layer 6 on one side, the compressive force on the first strain gauge 4 in the corresponding liquid storage chamber suddenly increases. The controller stops the cyclic cooling of the corresponding liquid storage chamber by controlling the solenoid valve 14, while the other liquid storage chambers can continue to cool and circulate. The buffering effect of the liquid storage chamber that stops cooling and circulating is greater than that of the other liquid storage chambers that continue cooling and circulating, thereby promoting the repositioning of the visceral specimen, reducing the shaking of the visceral specimen in the liquid storage chamber, and improving the stability of the visceral specimen during the movement of the device.

[0059] Example 2

[0060] As attached Figure 4-5 As shown, compared with Embodiment 1, the difference is that: a horizontal plate 15 is ball-jointed at the bottom of the placement chamber, and several spring plates 17 are fixedly connected in the gap between the horizontal plate 15 and the placement chamber. In this embodiment, the spring plates 17 are fixedly connected to the bottom of the placement chamber, and a second strain gauge 18 is fixedly connected below the spring plate 17 located at the edge. The second strain gauge 18 is connected to the controller signal. The controller receives the resistance value change signal of the second strain gauge 18. When the resistance value change signal of the second strain gauge 18 exceeds the threshold, the liquid cooling cycle in the corresponding liquid storage chamber is also stopped, thereby further improving the stability of the visceral specimen during the movement of the device.

[0061] In addition, to reduce the displacement of visceral specimens on the horizontal plate 15, a protective flange is fixedly connected to the edge of the horizontal plate 15, and the top of the protective flange has an arc-shaped structure.

[0062] The specific implementation process is as follows:

[0063] When the visceral specimen is shaken in a certain direction, when the shaking reaches a certain amplitude, the spring plate 17 will squeeze the second strain gauge 18. When the resistance value change signal of the second strain gauge 18 exceeds the threshold, the liquid cooling cycle in the corresponding liquid storage chamber will also stop, thereby further improving the stability of the visceral specimen during the movement of the device.

[0064] Example 3

[0065] Compared with Embodiment 2, the difference is that a temperature and humidity sensor is fixedly connected in the placement chamber, the temperature and humidity sensor is connected to the controller signal, and the display 7 displays the temperature and humidity data collected by the temperature and humidity sensor.

[0066] The specific implementation process is as follows:

[0067] When using this storage device, the temperature and humidity sensor monitors the temperature and humidity inside the storage chamber and displays it on the display 7. The user can obtain the temperature and humidity data inside the storage device without opening the cabinet 2.

[0068] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific structures and / or characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
