Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular, to a medical cold chain transport box. BACKGROUND

[0002] In the field of medical devices, biological products (such as blood, vaccines, medicines, etc.) often need to be transported under the premise of maintaining a certain temperature range, which requires the use of carriers such as cold chain transport vehicles, medical cold chain transport boxes, etc. to complete the transportation work. Medical cold chain transport boxes have inherent advantages in short-distance and small-scale transportation and are widely used. Convenience, speed, flexibility, and low cost are its main features.

[0003] Medical cold chain transport boxes generally use ice blocks, ice crystal boxes, ice bags, and dry ice as passive cold sources to achieve the purpose of keeping the biological products in the box warm. The conventional medical cold chain transport boxes on the market all place biological products at the bottom of the box, and the upper layer is used to place cold sources such as ice blocks, ice crystal boxes, and ice bags. This results in a lower temperature at the upper layer and a higher temperature at the bottom of the medical cold chain transport box, with the surrounding temperature being intermediate, and the overall temperature uniformity being poor. In order to ensure the overall temperature uniformity, cold sources can be placed on each face inside the medical cold chain transport box. Although the temperature uniformity is guaranteed, the operation is more troublesome and inefficient.

[0004] Therefore, there is a need in the art for a medical cold chain transport box with good temperature uniformity. SUMMARY

[0005] The purpose of the present application is to provide a medical cold chain transport box with good temperature uniformity.

[0006] In order to achieve the above purpose, the present application provides a medical cold chain transport box, which comprises a box body, a box cover, a cold conducting device, and a cold source placing structure for placing a cold source. The box body and the box cover are respectively formed by a heat preservation material. The box body is provided with a containing cavity. The cold source placing structure is detachably installed in the containing cavity. The cold conducting device is made of a material with high heat conduction efficiency. The cold conducting device is arranged in the containing cavity or embedded in the box body. The cold conducting device is detachably connected to the cold source placing structure, so that the cold energy of the cold source placed in the cold source placing structure is released into the containing cavity through the cold conducting device.

[0007] Specifically, the cold conducting device is a net basket detachably arranged in the containing cavity. The medical cold chain transport box comprises a medical biological product placing structure for placing medical biological products. The medical biological product placing structure is arranged in the cold conducting device. The cold source placing structure is detachably supported on the top of the cold conducting device.

[0008] Specifically, the cold source placement structure is a tray made of plastic, the medical biological product placement structure is a tray made of heat preservation material, and the cold conducting device is made of metal.

[0009] Specifically, the medical biological product placement structure is provided with a flow guide hole penetrating through itself, and the medical cold chain transportation box further comprises a flow guide pipe in abutment with the flow guide hole, and the top of the flow guide pipe is close to the bottom of the cold source placement structure.

[0010] Specifically, the top of the cold conducting device is provided with a handle.

[0011] Specifically, the box body comprises a thin-walled part and a thick-walled part arranged in sequence from shallow to deep, a step is formed between the thin-walled part and the thick-walled part, the cold source placement structure is a tray detachably supported on the step, and the cold conducting device comprises a plurality of cold conducting pieces embedded in the thick-walled part in sequence along the inner wall of the thick-walled part, and the top of the cold conducting piece is detachably abutted against the bottom of the cold source placement structure at the step.

[0012] Specifically, the thick-walled part is provided with a groove between adjacent cold conducting pieces, and the cold source placement structure is provided with a through hole corresponding to the groove.

[0013] Specifically, the medical cold chain transportation box comprises a positioning mounting seat and a remote monitoring module for collecting working state information of the medical cold chain transportation box and transmitting to a monitoring terminal, and the outer part of the box body is provided with a mounting recess for mounting the positioning mounting seat, the positioning mounting seat is mounted in the mounting recess, and the remote monitoring module is mounted in the positioning mounting seat.

[0014] Specifically, the positioning mounting seat is provided with a mounting position for mounting the remote monitoring module, and the remote monitoring module is detachably mounted in the mounting position.

[0015] Specifically, the positioning mounting seat comprises a base mounted in the mounting recess and a flip cover pivotally connected to the base, and the mounting position is arranged in the base.

[0016] The medical cold chain transportation box of the present application has the advantages of good heat preservation uniformity because the cold conducting device made of material with high heat conduction efficiency is arranged in the containing cavity of the box body or embedded in the box body, so that when the cold source placement structure is installed in the containing cavity and the cold source is placed on the cold source placement structure, the cold conducting device will be connected to the cold source placement structure, and therefore the cold energy of the cold source placed on the cold source placement structure can be uniformly released into the containing cavity through the cold conducting device.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0021] ​​​It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0023] This invention provides a medical cold chain transport box, specifically, as follows: Figures 1 to 5 As shown, the medical cold chain transport box includes a box body 1, a box lid 2, a cooling device 3, and a cold source placement structure 4 for placing a cold source 9. The box body 1 and the box lid 2 are respectively molded from insulation material. The box body 1 is provided with a receiving cavity. The cold source placement structure 4 is detachably installed in the receiving cavity. The cooling device 3 is made of a material with high thermal conductivity. The cooling device 3 is disposed in the receiving cavity or embedded in the box body 1. The cooling device 3 is detachably connected to the cold source placement structure 4 so that the cold energy of the cold source 9 placed in the cold source placement structure 4 can be released into the receiving cavity through the cooling device 3.

[0024] The medical cold chain transport box of the present invention includes a cooling device 3 made of a material with high thermal conductivity. The cooling device 3 is disposed in or embedded in the receiving cavity of the box body 1. Therefore, when the cold source placement structure 4 is installed in the receiving cavity and the cold source 9 is placed on the cold source placement structure 4, the cooling device 3 will connect to the cold source placement structure 4. Thus, the cold energy of the cold source 9 placed on the cold source placement structure 4 can be evenly released into the receiving cavity through the cooling device 3. It can be seen that the medical cold chain transport box of the present invention has the advantage of good heat preservation uniformity.

[0025] It should be noted that the specific structural forms and material types of the box body 1, box lid 2, cooling device 3, cold source placement structure 4, and accommodating cavity, the specific implementation method of detachably installing the cold source placement structure 4 in the accommodating cavity, and the specific arrangement method of the cooling device 3 can all be configured as needed. These are all within the scope of the technical concept of this invention. For example, the box body 1 and box lid 2 can be molded from EPP foam. Furthermore, it should be noted that the medical cold chain transport box of this invention can be used for cold chain transport of biological products such as blood, vaccines, and pharmaceuticals.

[0026] In a first specific embodiment of the medical cold chain transport box of the present invention, specifically, as follows: Figure 2 and Figure 3 As shown, the cooling device 3 is a wire basket detachably installed in the accommodating cavity. The medical cold chain transport box includes a medical biological product placement structure 5 for placing the medical biological product 10. The medical biological product placement structure 5 is installed inside the cooling device 3. The cold source placement structure 4 is detachably supported on the top of the cooling device 3. Thus, the staff can place the medical biological product 10 that needs to be transported by cold chain into the medical biological product placement structure 5, then support the cold source placement structure 4 on the top of the cooling device 3, then place the cold source on the cold source placement structure 4, and finally install the cooling device 3 together with the medical biological product placement structure 5 and the cold source placement structure 4 into the accommodating cavity and close the box lid 2, thereby realizing the cold chain preservation of the medical biological product 10 (this is the working state of the medical cold chain transport box of the present invention).

[0027] More specifically, in the medical cold chain transport box of the present invention, the cold source placement structure 4 is a tray made of plastic, the medical biological product placement structure 5 is a tray made of insulating material (e.g., EPP foam), and the cooling device 3 is made of metal (e.g., copper, aluminum, or alloy materials). Therefore, the cold source placement structure 4 can reduce the efficiency of cold energy transfer to the cooling device 3, preventing the cooling device 3 from becoming too cold and causing damage to the medical biological products in direct contact with the cooling device 3.

[0028] It should be noted that in other specific embodiments, the cooling device 3 may also have other specific structural forms. For example, the cooling device 3 may be a thin-walled metal box that is attached to the inner wall of the box 1.

[0029] In the medical cold chain transport box of the present invention, more specifically, the center of the medical biological product placement structure 5 is provided with a through-hole, and the medical cold chain transport box also includes a guide pipe 6 connected to the guide hole. The top of the guide pipe 6 is close to the bottom of the cold source placement structure 4. Thus, when the medical cold chain transport box of the present invention is in operation, the relatively high temperature gas located between the inner bottom wall of the cavity and the bottom of the medical biological product placement structure 5 can flow through the guide pipe 6 to the bottom of the cold source placement structure 4 to achieve cooling, thereby further improving the heat preservation uniformity of the medical cold chain transport box of the present invention.

[0030] In the medical cold chain transport box of the present invention, preferably, the top and bottom of the guide tube 6 are provided with radial side holes so that the gas can diffuse better; the top of the cooling device 3 is provided with a handle 31 so that the staff can install the cooling device 3 together with the medical biological product placement structure 5 and the cold source placement structure 4 into the receiving cavity and take it out of the receiving cavity.

[0031] In a second specific embodiment of the medical cold chain transport box of the present invention, specifically, as follows: Figure 4 and Figure 5 As shown, the housing 1 includes a thin-walled portion 11 and a thick-walled portion 12 arranged sequentially from shallow to deep. A step is formed between the thin-walled portion 11 and the thick-walled portion 12. The cold source placement structure 4 is a tray made of plastic that is detachably supported on the step. The cooling device 3 includes a plurality of cooling conductive elements 32 sequentially embedded in the thick-walled portion 12 along the inner wall of the thick-walled portion 12. The top of the cooling conductive element 32 is detachably abutted against the bottom of the cold source placement structure 4 at the step. The cooling conductive element 32 is made of a material with high thermal conductivity (such as copper, aluminum, or other metals or alloys), so that workers can transport medical and biological products that require cold chain transportation. The medical biological product 10 is placed in the deeper part of the cavity (i.e., the cavity formed by the thick-walled part 12 and the inner bottom wall of the box body 1), and then the cold source placement structure 4 is supported on the step (at this time, the top of the cooling conductor 32 will abut against the bottom of the cold source placement structure 4). Then, the cold source is placed on the cold source placement structure 4, and finally the box cover 2 is closed, thereby realizing the cold chain preservation of the medical biological product 10 (this is the working state of the medical cold chain transport box of the present invention). In addition, since the staff can easily place and take out the medical biological product 10 and the cold source placement structure 4, the above-described second specific embodiment of the medical cold chain transport box of the present invention also has the advantage of being easy to use.

[0032] More specifically, in the medical cold chain transport box of the present invention, the thick-walled portion 12 is provided with a groove between adjacent cold-conducting elements 32, and the cold source placement structure 4 is provided with a through hole corresponding to the groove, thereby improving the diffusion efficiency of cold energy.

[0033] In the medical cold chain transport box of the present invention, preferably, as shown below, Figure 2 As shown, the medical cold chain transport box includes a positioning mounting base 7 and a remote monitoring module 8 for collecting the working status information of the medical cold chain transport box and transmitting it to a monitoring terminal. Thus, the working status information of the medical cold chain transport box of the present invention can be collected and transmitted to the monitoring terminal through the remote monitoring module 8. Furthermore, the exterior of the box body 1 is provided with a mounting recess for installing the positioning mounting base 7. The positioning mounting base 7 is installed in the mounting recess, and the remote monitoring module 8 is installed in the positioning mounting base 7. Because the positioning mounting base 7 and the remote monitoring module 8 are installed in the mounting recess (i.e., the positioning mounting base 7 and the remote monitoring module 8 are embedded in the box body 1), it facilitates the installation and transportation of the medical cold chain transport box of the present invention while also protecting the remote monitoring module 8 from damage by external forces.

[0034] In the medical cold chain transport box of the present invention, specifically, the positioning mounting base 7 is provided with a mounting position for installing the remote monitoring module 8. The remote monitoring module 8 is detachably installed in the mounting position, so that the staff can disassemble and assemble the remote monitoring module 8 as needed for charging and other operations.

[0035] More specifically, in the medical cold chain transport box of the present invention, the positioning mounting base 7 includes a base 71 mounted in the mounting recess and a flip cover 72 pivotally connected to the base 71. The mounting position is located on the base 71, so that the remote monitoring module 8 can be further protected by the flip cover 72, making it difficult to be damaged by external forces.

[0036] The preferred embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0037] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0038] Furthermore, various different implementations of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed in this application.
