Description

Technical Field

[0001] This utility model relates to the field of refrigerated transport technology, specifically a refrigerated transport box for biological reagents. Background Technology

[0002] Refrigerated transport boxes play a crucial role in the storage and transport of biological reagents in the biomedical field. A refrigerated transport box is a device specifically designed to preserve biological samples requiring a low-temperature environment, ensuring the quality of biological samples during transport by maintaining a stable low temperature. The design of refrigerated transport boxes typically includes insulation layers and a cooling mechanism to effectively maintain the required low-temperature environment. However, while these refrigerated transport boxes effectively guarantee the quality of biological samples, some problems exist in practical applications. To improve ease of use and reduce costs, multiple refrigerated transport boxes are often mounted on trolleys for convenient handling. This approach does solve the problem of difficult handling, but the refrigerated transport boxes themselves are heavy, as they are usually equipped with thick insulation layers and complex cooling systems, resulting in high costs when replacing transport boxes and increasing the operational burden on hospitals. Furthermore, these refrigerated transport boxes often require charging, necessitating separate charging after each use. This not only increases equipment maintenance costs but also increases the workload of users, significantly reducing the efficiency of the transport process. Summary of the Invention

Detailed Implementation

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments. Example

[0025] like Figures 1-8As shown, a biological reagent cold transport box in one embodiment of the present invention includes a base 1 and multiple transport units 6 installed on the base 1. The transport units 6 can be installed on the base 1, and the transport units 6 can also be stacked. Multiple transport units 6 installed on the base 1 form a 1+N modular layout, which can facilitate the cold transport of multiple biological reagents.

[0026] like Figures 1-6 As shown, the base 1 includes a base plate 2. A refrigeration system 4 is fixedly connected to the lower end of the base plate 2. A first connecting post 201 matching the refrigeration system 4 is also fixedly connected to the lower end of the base plate 2. The first connecting post 201 is located around the refrigeration system 4, and its lower end face is equal to or lower than the lower end face of the refrigeration system 4. An industrial caster 3 is fixedly connected to the lower end of the first connecting post 201. A first handle 5 is fixedly connected to the base plate 2. Pushing the industrial caster 3 forces the industrial caster 3 to move the base plate 2.

[0027] To ensure the needs of outdoor use or in scenarios without external power supply, the cooling system 4 is specially equipped with an independent battery, which can provide independent power for a long time and ensure continuous cooling.

[0028] like Figures 1 to 8 As shown, a housing 7 is installed on the transfer unit 6. A connector 701 is fixedly connected to the lower end of the housing 7. A second through hole 702 matching the connector 701 is provided on the housing 7. A first groove 202 matching the connector 701 is provided on the bottom plate 2. A first through hole 203 matching the second through hole 702 is also provided on the bottom plate 2. A cooling pipe 401 matching the first through hole 203 is installed on the refrigeration system 4. The cooling air generated by the refrigeration system 4 is discharged from the cooling pipe 401, passes through the first through hole 203, and then enters the second through hole 702.

[0029] like Figures 1 to 7 As shown, the box 7 has a vent 703 that matches the second through hole 702. When cold air is input from the second through hole 702, some of the cold air enters the interior of the box 7 through the vent 703. The biological reagent is placed inside the box 7 to achieve the cooling of the biological reagent.

[0030] like Figures 1 to 7 As shown, a cover 8 is rotatably connected to the box body 7, and a second handle 803 is rotatably connected to the cover 8. The cover 8 can seal the upper opening of the box body 7.

[0031] In the above embodiment, although the refrigeration system 4 can deliver cold air to the biological reagent, some of the cold air will be discharged through the upper end of the second through-hole 702, and the housing 7 is not sealed. To solve the above problem, such as... Figures 1-6As shown, a first sealing mechanism 9 and a second sealing mechanism 13 are fixedly connected inside the second through hole 702. The first sealing mechanism 9 is located at the upper part of the second through hole 702, and the second sealing mechanism 13 is located at the lower part of the second through hole 702. A first sealing mechanism 9 is also fixedly connected inside the first through hole 203. This arrangement allows the first sealing mechanism 9 and the second sealing mechanism 13 to precisely cooperate to control the opening and closing of the cold air passage when the transfer unit 6 is spliced ​​with the base 1 or when the transfer units 6 are stacked together, ensuring both effective cold air delivery and preventing leakage.

[0032] When the housing 7 is inserted into the base 1 via the plug-in post 701, the first sealing mechanism 9 on the base plate 2 contacts the second sealing mechanism 13 on the housing 7, and the two cooperate to connect the first through hole 203 and the second through hole 702, thereby controlling the cold air delivery. When the two transfer units 6 are stacked, the second sealing mechanism 13 on the upper housing 7 cooperates with the first sealing mechanism 9 on the lower housing 7 to connect the two second through holes 702.

[0033] like Figures 1-6 As shown, the first sealing mechanism 9 includes a first connecting frame 704, a second connecting post 11 slidably connected to the first connecting frame 704, a first sealing member 10 fixedly connected to the lower end of the second connecting post 11, a first circular handle 1101 fixedly connected to the upper end of the second connecting post 11, and a first spring 12 sleeved on the second connecting post 11, located between the first connecting frame 704 and the first circular handle 1101. In the initial state, the first sealing member 10 is in contact with the first connecting frame 704. During the contact process between the first sealing member 10 and the first connecting frame 704, the first sealing member 10 can seal the upper end of the second through hole 702 or the air conditioning pipe 401.

[0034] like Figures 1-6 As shown, the second sealing mechanism 13 includes a second connecting frame 14, a third connecting post 15 slidably connected to the second connecting frame 14, a second sealing member 16 fixedly connected to the lower end of the third connecting post 15, a second circular handle 1501 fixedly connected to the upper end of the third connecting post 15, a second spring 17 sleeved on the third connecting post 15, the second spring 17 being located between the second connecting frame 14 and the second sealing member 16, and a protruding ring 7021 matching the second sealing member 16 fixedly connected to the inner wall of the second through hole 702. In the initial state, the second spring 17 pushes the second sealing member 16 into contact with the protruding ring 7021. Thus, the lower part of the second through hole 702 is blocked by the first sealing mechanism 9, and the upper part of the second through hole 702 is blocked by the second spring 17.

[0035] like Figures 1-6As shown, a protruding post is fixedly connected to the lower end of the second sealing member 16. When the transfer unit 6 is spliced ​​onto the base plate 2, the protruding post contacts the first circular handle 1101 first. Continuing to press the transfer unit 6 downwards causes the first spring 12 to deform, creating a gap between the first connecting frame 704 and the first sealing member 10. At this time, the first sealing mechanism 9 is in the open state. At this point, the first spring 12 is fully deformed. Continuing to press the transfer unit 6 downwards causes the second spring 17 to deform, creating a gap between the second sealing member 16 and the protruding ring 7021. At this time, the second sealing mechanism 13 is in the open state. Thus, the first through hole 203 and the second through hole 702 can communicate with each other, as well as the second through hole 702 and the second through hole 702 can communicate with each other.

[0036] like Figures 1 to 8 As shown, the cover 8 has a second groove 801 that matches the insertion post 701, and a third through hole 802 that matches the second through hole 702. When the two transfer units 6 are spliced, the insertion post 701 is inserted into the second groove 801, and the second through hole 702 and the third through hole 802 communicate with each other.

[0037] In the above embodiments, when the transfer unit 6 is spliced ​​with the base 1 or when the transfer units 6 are stacked together, the opening process of the cold air passage is precisely achieved in two steps:

[0038] Step 1: During the initial pressing and splicing, the lower protrusion of the second sealing member 16 of the upper transfer unit 6 first contacts the first circular handle 1101 of the lower first sealing mechanism 9. Continuing to press downwards, the protrusion pushes the first circular handle 1101, causing the second connecting post 11 to move downwards. The first spring 12 is compressed and deformed, separating the first sealing member 10 from the first connecting frame 704, creating a gap. At this point, the first sealing mechanism 9 switches to the open state.

[0039] Step 2: When the pressure continues to be applied downwards to make the transfer unit 6 fully seated, the second spring 17 is further compressed and deformed. The third connecting column 15 drives the second sealing member 16 to move upwards. The second sealing member 16 separates from the convex ring 7021 and forms a gap. The second sealing mechanism 13 then switches to the open state.

[0040] The design of the first sealing mechanism 9 and the second sealing mechanism 13 ensures that the channel between the base 1 and the transfer unit 6 or adjacent transfer unit 6 is only opened after they are fully spliced ​​in place, minimizing the loss of cold air.

[0041] In other words, when the transfer unit 6 is attached to the base 1, or when the transfer unit 6 is attached to the transfer unit 6, the cold air in the refrigeration system 4 can be delivered to multiple transfer units 6 to ensure the cooling of the biological reagents in the transfer unit 6.

[0042] The beneficial effects of this embodiment are:

[0043] Compared to the traditional design of one transfer box and one refrigeration mechanism, this solution combines a unified refrigeration system 4 with a controllable sealed channel to provide a stable cold source for N transfer units 6 with a single refrigeration mechanism. This avoids equipment redundancy caused by multiple refrigeration mechanisms, and the sealing mechanism precisely controls the distribution of cold air, ensuring that each transfer unit 6 receives uniform cooling. It also reduces equipment procurement costs and maintenance complexity, and solves the problems of high energy consumption and poor consistency associated with traditional multiple refrigeration systems 4.

[0044] Furthermore, the modular layout improves transport efficiency, and the stacked design allows for flexible adaptation to the simultaneous transport of multiple reagents. Compared to traditional single-unit transport boxes, the transport volume can be adjusted as needed, significantly reducing the cost of multiple transports. Simultaneously, the optimized first sealing mechanism 9 and second sealing mechanism 13 reduce energy consumption. The dual sealing of the first sealing mechanism 9 and second sealing mechanism 13 initially prevents cold air leakage, and the channel is only opened after they are fully assembled, solving the cold air leakage problem of traditional structures. Combined with independent battery power, the refrigeration endurance is extended. The combination of industrial casters 3 and the first handle 5 enables convenient movement, and the independent battery adapts to scenarios without external power, meeting the transport needs of various scenarios such as outdoor use and emergency rescue. The interconnected design of the vent 703 and the second through hole 702 allows cold air to diffuse evenly into the interior of the box 7, and with the sealing of the lid 8, ensures the stability of the reagent storage environment and improves the safety of reagent transport. Example

[0045] An air vent 18 is installed inside the housing 7, forming a placement cavity 19 between the air vent 18 and the housing 7. A cooling radiator is installed inside the placement cavity 19. In actual use, the cooling radiator can refrigerate biological reagents for a certain period of time in a non-contained state.

[0046] When the transfer unit 6 is detached from the base 1, in scenarios such as reagent transfer between departments, short-distance point-to-point transport, and temporary sample storage, the cooling radiator in the placement chamber 19 can directly release cold energy to maintain the low temperature inside the cabinet 7, eliminating the need for additional independent refrigeration equipment. This significantly expands the applicable scenarios of the transfer unit 6 and reduces reliance on fixed refrigeration facilities. In other words, it can stably release cold energy in the non-connected state, maintaining the low-temperature environment inside the cabinet 7 for 2-4 hours, fully meeting the needs of short-distance independent transport between departments within the hospital, and between laboratories and testing rooms, avoiding the risk of reagent activity degradation or deterioration due to lack of continuous cooling.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
