Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a low-temperature dry ice temperature zone medical insulated box. Background Technology

[0002] In the medical field, many pharmaceuticals and biological samples require preservation and transportation in specific low-temperature environments to ensure their activity and quality. Dry ice, which can provide a low-temperature environment of around -78.5°C upon sublimation, is widely used for the preservation of medical items with extremely stringent temperature requirements. However, a drawback is that in actual use, the temperature is often lower near the dry ice or refrigeration components, while higher at locations further away, resulting in uneven temperature distribution within the insulated box. To address this drawback, existing technology (Chinese patent application number: 202120262419.X, authorized announcement date: 2021-11-26) discloses a medical refrigerated insulated box. The user first opens the box lid, then places the medical supplies to be stored into the temperature transfer placement slot. The user then closes the lid, at which point the connector is inserted into the latch, completing the closing process. A fixed temperature sensor inside the refrigerator monitors the internal temperature and transmits it to an LCD screen for display. When the temperature exceeds a certain threshold, the user can activate the exhaust fan, fan motor, and thermoelectric cooling plate via the control panel. The exhaust fan draws in outside air, while the thermoelectric cooling plate utilizes the thermoelectric effect to create a cold end and a hot end on each side. The cold end is attached to a temperature transfer slot, which rapidly conducts heat into the refrigerator, quickly lowering the temperature of medical supplies. Meanwhile, the fan motor drives the drive shaft to rotate, which in turn drives the fan blades to quickly blow the heated air around the hot end of the thermoelectric cooling plate out of the refrigerator through the ventilation mesh, further reducing the temperature of the hot end of the thermoelectric cooling plate. Simultaneously, it further reduces the temperature of the cold end of the thermoelectric cooling plate, thus enhancing the cooling effect of the device.

[0003] Existing technology uses a fan motor to rotate the fan blades, which quickly blows the heated air around the hot end of the semiconductor cooling plate out of the refrigerated box through the ventilation mesh. However, the box lacks layered management, which means that all items can only be placed in one space. It is difficult to clearly classify medical items of different types, specifications, and uses. At the same time, items of different properties and cleanliness levels cannot be effectively isolated and are prone to contact with each other, increasing the risk of cross-contamination. Therefore, we proposed a low-temperature dry ice temperature zone medical insulated box, which can effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature dry ice temperature zone medical insulated box to solve the problems mentioned in the background art, such as the lack of layered management inside the box, which makes it difficult to clearly classify medical items of different types, specifications and uses, and the inability to effectively isolate items of different properties and cleanliness levels, which easily come into contact with each other and increase the risk of cross-contamination.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature dry ice temperature zone medical insulated box, comprising a box body, a box cover hinged to the top of the box body, and a dust cover fixedly provided on the top of the box cover, an air intake fan installed inside the dust cover, and a tray connected to the bottom of the box cover; characterized in that it further comprises: partition plates provided inside the box body, and a drive plate slidably connected inside the partition plates, positioning blocks symmetrically connected inside the partition plates about the center point of the drive plate, two positioning blocks being connected to the drive plate through connecting plates, a return spring installed between the bottom of the drive plate and the inner wall of the partition plate, and positioning grooves equally spaced at both ends of the box body.

[0006] Preferably, the top of the drive plate extends beyond the upper surface of the partition plate, and the positioning block is slidably disposed inside the partition plate, with the positioning block corresponding to the position of the positioning groove.

[0007] Preferably, both ends of the connecting plate are hinged to the end of the positioning block and the outer side of the driving plate, respectively.

[0008] Preferably, a sealing strip is adhered to the bottom of the box lid, and sealing grooves are formed around the top of the box body. The sealing strip and the sealing grooves are connected by a snap-fit ​​connection.

[0009] Preferably, sliders are fixed on both the left and right sides of the tray, and the tray is slidably disposed at the bottom of the box cover by the two sliders. Limiting grooves are provided on the sides of the sliders. Limiting blocks are slidably connected to the left and right sides inside the box cover, and tension springs are installed between the outer side of the limiting blocks and the inner wall of the box cover.

[0010] Preferably, the slider is T-shaped, the limiting block is C-shaped, and the limiting block and the limiting groove are connected by an insertion.

[0011] Preferably, the interior of the housing is provided with a reflective layer, and a pressure balancing component is installed on the left side of the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This low-temperature dry ice temperature zone medical insulated box adopts a novel structural design, the specific details of which are as follows:

[0013] (1) The multiple partitions can be used to divide the interior of the box into multiple independent partitions, which is convenient for classifying and storing different types of medical items. By pulling the drive plate upward and using the two connecting plates to drive the two positioning blocks to move relative to each other, the partitions are separated from their initial positioning slots, and the partitions can be moved. The size of the internal space of the box can be adjusted according to the size of the medical items, which is convenient for storing medical items of different sizes. Furthermore, after the partitions are moved, the drive plate is released so that it is reset under the elastic force of the return spring. The two connecting plates can drive the two positioning blocks to move in opposite directions so that they are inserted into the corresponding positioning slots, thus fixing the moved partitions.

[0014] (2) When the lid is placed on the box body, the sealing strip is inserted into the sealing groove, thereby improving the sealing of the connection between the lid and the box body. The dry ice sublimation absorbs the heat in the surrounding environment, thereby making the inside of the insulated box reach a low temperature state, providing the necessary low temperature environment for storing medical items. The low temperature gas is pushed to all parts of the box body by the rotation of the intake fan. Furthermore, the reflective layer can reflect the heat back, reducing the heat entering the box through radiation, and further enhancing the heat preservation effect.

[0015] (3) The pressure balancing component can open the one-way valve when the pressure inside the chamber is lower than the external pressure, allowing outside air to enter the chamber through the filter membrane to balance the pressure inside the chamber. At the same time, the filter membrane can prevent dust, bacteria and other impurities from entering the chamber. When the pressure inside the chamber is higher than the external pressure, the one-way valve closes to prevent gas leakage inside the chamber.

[0016] (4) When it is necessary to replace the dry ice, simply pull the two limit blocks outward to separate them from the limit groove, which can release the limit on the slider and pull the tray to separate it from the box cover, so as to facilitate the removal and replacement of the dry ice to ensure the subsequent cooling effect.

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a low-temperature dry ice temperature zone medical insulated box;

[0026] Example 1: To address the problem in the prior art where the interior of the housing 1 lacks layered management, resulting in all items being placed in a single space, making it difficult to clearly classify medical supplies of different types, specifications, and uses, and preventing effective isolation of items of different properties and cleanliness levels, thus increasing the risk of cross-contamination, the following solution is disclosed. Please refer to the following for details. Figures 1-3 and Figure 6 As shown, the device includes a housing 1, with a lid 2 hinged to the top of the housing 1. A dust cover 3 is fixedly installed on the top of the lid 2, and an intake fan 4 is installed inside the dust cover 3. A tray 5 is connected to the bottom of the lid 2. The device also includes partitions 10 inside the housing 1, with a drive plate 11 slidably connected inside each partition 10. Positioning blocks 12 are symmetrically connected inside each partition 10 about the center point of the drive plate 11. Both positioning blocks 12 are connected to the drive plate 11 via connecting plates 14, with both ends of the connecting plates 14 connected to the positioning blocks 12. The ends of the drive plate 11 and the outer side of the drive plate 11 are hinged. A return spring 13 is installed between the bottom of the drive plate 11 and the inner wall of the partition plate 10. Positioning grooves 15 are equally spaced at the front and rear ends of the box body 1. The top of the drive plate 11 extends out of the upper surface of the partition plate 10. The positioning block 12 is slidably set inside the partition plate 10. The positioning block 12 corresponds to the position of the positioning groove 15. A sealing strip 7 is glued to the bottom of the box cover 2. A sealing groove 8 is opened around the top of the box body 1. The sealing strip 7 and the sealing groove 8 are engaged.

[0027] During use, medical staff put different types of medical supplies into the box body 1. The multiple partition boards 10 provided can divide the interior of the box body 1 into multiple independent compartments, facilitating the classified storage of different types of medical supplies. By pulling up the driving plate 11 upward and using the two connecting plates 14 to drive the two positioning blocks 12 to move relatively, they are separated from the positioning grooves 15 in the initial position, releasing the limit on the partition board 10. At this time, the partition board 10 can be moved, so as to adjust the internal space size of the box body 1 according to the size of the medical supplies, facilitating the storage of medical supplies of different sizes. Then, when the movement of the partition board 10 is completed, release the driving plate 11, and it will reset under the elastic force of the return spring 13. The two connecting plates 14 can drive the two positioning blocks 12 to move in the opposite direction, making them insert into the corresponding positioning grooves 15 to fix the moved partition board 10. Then cover the box cover 2. At this time, the sealing strip 7 on the box cover 2 is inserted into the sealing groove 8, thereby improving the sealing performance of the connection position between the box cover 2 and the box body 1. The sublimation of dry ice absorbs the heat in the surrounding environment, so that the inside of the incubator reaches a low temperature state, providing the required low temperature environment for storing medical supplies, and through the rotation of the intake fan 4, the low temperature gas is pushed to各处 inside the box body 1.

[0028] Embodiment 2: Different from Embodiment 1, this embodiment can facilitate the replacement of the dry ice inside the tray 5 to ensure the subsequent refrigeration effect. Specifically refer to Figure 1 and Figure 3 As shown, sliders 6 are fixed on both the left and right sides of the tray 5, and the tray 5 is slidably arranged at the bottom of the box cover by means of the two sliders 6. Limiting grooves are provided on the sides of the sliders 6. Limiting blocks 9 are slidably connected to both the left and right sides inside the box cover 2, and a tension spring is installed between the outer sides of the limiting blocks 9 and the inner walls of the box cover 2. The sliders 6 are arranged in a "T" shape, the limiting blocks 9 are arranged in a "匚" shape, and the limiting blocks 9 and the limiting grooves are in an insertion connection.

[0029] When dry ice needs to be replaced, medical staff only need to pull the two limiting blocks 9 outward to separate them from the limiting grooves, releasing the limit on the sliders 6, and pull the tray 5 to separate it from the box cover 2, thereby facilitating the removal and replacement of the dry ice to ensure the subsequent refrigeration effect. Then, clean the remaining dry ice inside the tray 5, pour in new dry ice, and insert the tray 5 into the card slot on the box cover 2 through the sliders 6. Then release the limiting blocks 9, and the limiting blocks 9 will reset under the elastic force of the tension spring and insert into the corresponding limiting grooves, which can fix the sliders 6 and complete the replacement of the dry ice.

[0030] Embodiment 3: Different from Embodiment 2, this embodiment uses the provided reflective layer 16 to reduce the heat entering the box by radiation, further enhancing the heat preservation effect. Specifically refer to Figure 5As shown, a reflective layer 16 is provided inside the box 1, and a pressure balancing component 17 is installed on the left side of the box 1.

[0031] The reflective layer 16 reflects heat back, reducing the amount of heat entering the chamber 1 through radiation and further enhancing the insulation effect. The pressure balancing component 17 opens the one-way valve when the pressure inside the chamber 1 is lower than the external pressure, allowing outside air to enter the chamber through the filter membrane to balance the pressure inside the chamber 1. At the same time, the filter membrane prevents dust, bacteria and other impurities from entering the chamber 1. When the pressure inside the chamber 1 is higher than the external pressure, the one-way valve closes to prevent gas leakage from the chamber.
