Description

Technical Field

[0001] This application relates to the field of mobile medical cabin and its insulation module. Background Technology

[0002] A mobile medical unit is an integrated medical facility, typically designed as a portable, modular structure capable of rapid deployment and providing temporary medical services. It is widely used in emergency situations such as disaster relief, epidemic prevention and control, battlefield medicine, and medical services in remote areas. Especially when traditional medical facilities are difficult to establish quickly, mobile medical units can effectively fill gaps in medical resources. Through flexible configuration, mobile medical units can be set up as emergency rooms, operating rooms, intensive care units, laboratories, etc., to meet the medical needs of different scenarios.

[0003] In existing technologies, many mobile medical cabins use conventional insulation materials, such as polyurethane foam, to ensure stable temperature inside the cabin. However, these traditional insulation materials have limitations in dealing with extreme environmental conditions, especially when external energy is suddenly interrupted (such as power outages, fuel shortages, or air conditioning system malfunctions), they cannot effectively maintain stable temperature inside the cabin. Particularly when external ambient temperatures fluctuate drastically, traditional insulation materials often cannot continuously provide sufficient heat or cooling, leading to excessively high or low temperatures inside the cabin, severely impacting the normal operation of medical equipment and the work efficiency of medical staff. Utility Model Content

[0004] Therefore, this application provides a mobile medical cabin and its insulation module to solve the problem in the prior art that it is impossible to effectively maintain the stable temperature inside the cabin under extreme environmental conditions, especially the failure of temperature control when external power is interrupted.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A thermal insulation module suitable for mobile medical cabins includes a shell for connecting to the inner wall of the mobile medical cabin. The shell has a receiving cavity for containing a phase change fluid. The shell has an injection port communicating with the receiving cavity and for injecting the phase change fluid. The shell is detachably connected to the inner wall of the mobile medical cabin via a connecting assembly.

[0007] Optionally, the shell is a rectangular body, the side wall of the rectangular body is bent to form a relief groove, the liquid injection port is located on the groove wall of the relief groove, and the groove wall of the relief groove forms a liquid injection pipe that cooperates with the liquid injection port at the liquid injection port.

[0008] The connecting component includes multiple first threaded holes formed in the shell and penetrating through itself, and multiple fasteners that cooperate with the first threaded holes. The multiple first threaded holes and the multiple fasteners correspond one-to-one. The inner wall of the mobile medical cabin is provided with multiple second threaded holes that cooperate with the first threaded holes. The multiple first threaded holes and the multiple second threaded holes correspond one-to-one.

[0009] Optionally, the plate shell has gripping holes on its opposite sides that penetrate through it and are easy for a person to grip.

[0010] Optionally, the dimensions of the rectangle are 380*290*25mm.

[0011] Optionally, the shell is made of HDPE material, and the phase change fluid is a mixture of resin and nanocapsules.

[0012] Optionally, the phase transition point of the nanocapsule is 26°C or 17°C, and the enthalpy of the nanocapsule is greater than 150 kJ / kg.

[0013] This application also discloses a mobile medical cabin, wherein the inner wall of the mobile medical cabin is connected to the heat insulation module as described above.

[0014] Compared with the prior art, this application has at least the following beneficial effects:

[0015] The thermal insulation module of the mobile medical cabin provided in this application forms a continuous temperature control barrier by sequentially laying and connecting multiple shell panels to the inner wall of the cabin, thereby effectively insulating the internal environment of the cabin. Each shell panel contains a cavity filled with a phase change fluid. The phase change fluid has the characteristics of a phase change material, capable of absorbing or releasing a large amount of heat when the temperature changes. When the external temperature is low, the phase change fluid can absorb heat from the surrounding environment and undergo a phase change, storing thermal energy; while when the external temperature rises, the phase change fluid releases the stored heat, helping to maintain a stable internal temperature.

[0016] Because phase change fluids have high energy storage density and long-term heat release capabilities, they can effectively prevent drastic temperature fluctuations during temperature regulation, thereby ensuring the comfort and safety of equipment, medicines, and personnel within the mobile medical unit. This phase change energy storage technology enables the mobile medical unit to maintain a suitable temperature range of 18-25℃ for extended periods, even when the external environment undergoes drastic changes, ensuring the smooth operation of various medical activities within the unit.

[0017] Furthermore, the mobile medical module is designed for disassembly and reassembly. Therefore, the insulation module's shells can be easily disassembled and reassembled using connecting components, allowing for rapid maintenance, cleaning, or component replacement when needed. The injection port design on each shell allows for the injection or replacement of phase change fluid as required. When the phase change fluid fails, it can be easily replaced through this injection port, extending the module's lifespan and maintaining optimal thermal regulation. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0027] refer to Figure 1-4 This application discloses a thermal insulation module suitable for mobile medical cabins, including a shell 1 for connecting to the inner wall of the mobile medical cabin 2. The shell 1 has a receiving cavity 17 for containing phase change fluid, and the shell 1 has an injection port 12 that communicates with the receiving cavity 17 and is used for injecting phase change fluid. The shell 1 is detachably connected to the inner wall of the mobile medical cabin 2 through a connecting assembly.

[0028] The thermal insulation module of the mobile medical cabin 2 provided in this application forms a continuous temperature control barrier by sequentially laying and connecting multiple shell panels 1 to the inner wall of the cabin, thereby effectively insulating the internal environment of the cabin. Each shell panel 1 has a receiving cavity 17 filled with a phase change fluid. The phase change fluid has the characteristics of a phase change material, which can absorb or release a large amount of heat when the temperature changes. When the outside temperature is low, the phase change fluid can absorb heat from the surrounding environment and undergo a phase change to store thermal energy; when the outside temperature rises, the phase change fluid releases the stored heat to help maintain a stable temperature inside the cabin.

[0029] Because phase change fluids have high energy storage density and long-term heat release capabilities, they can effectively prevent drastic temperature fluctuations during temperature regulation, thereby ensuring the comfort and safety of equipment, medicines, and personnel within the mobile medical unit. This phase change energy storage technology enables the mobile medical unit 2 to maintain a suitable temperature range of 18-25℃ for extended periods, even when the external environment undergoes drastic changes, ensuring the smooth operation of various medical activities within the unit.

[0030] Furthermore, the mobile medical module 2 is designed for disassembly and reassembly. Therefore, the insulation module's shell 1 can be easily disassembled and reassembled via connecting components, allowing for rapid maintenance, cleaning, or component replacement when needed. The injection port 12 on each shell 1 allows for the injection or replacement of phase change fluid as required. When the phase change fluid fails, it can be easily replaced through this injection port 12, extending the module's lifespan and maintaining optimal thermal regulation.

[0031] It should be noted that this insulation module is not only suitable for the Mobile Medical Container 2, but can also be applied to other places that require temperature regulation, such as temporary medical facilities, disaster relief stations, and field operation sites, as needed.

[0032] In some embodiments, multiple shells 1 can be prepared and heated by external devices so that the insulation module can store heat or cold before use. After the shells 1 are heated or cooled to a predetermined temperature, they are installed in the mobile medical cabin 2 to ensure that the temperature inside the cabin is stable.

[0033] In some embodiments, the shell 1 can store heat through heating or cooling of the mobile medical cabin 2 itself.

[0034] The shell 1 is a rectangular body. The side wall of the rectangular body is bent to form a relief groove 11. The liquid injection port 12 is located on the groove wall of the relief groove 11, and the groove wall of the relief groove 11 has a liquid injection pipe 13 that cooperates with the liquid injection port 12 at the liquid injection port 12.

[0035] The connecting component includes multiple first threaded holes 14 that are opened in the shell 1 and pass through it, and multiple fasteners 15 that cooperate with the first threaded holes 14. The multiple first threaded holes 14 and the multiple fasteners 15 correspond one-to-one. The inner wall of the mobile medical cabin 2 is provided with multiple second threaded holes that cooperate with the first threaded holes 14. The multiple first threaded holes 14 and the multiple second threaded holes correspond one-to-one.

[0036] The shell 1 adopts a rectangular structure. Its regular geometry facilitates the alignment of multiple adjacent rectangles, effectively avoiding installation difficulties or large gaps caused by irregular shapes. The bend in the sidewalls of the rectangles to form a clearance groove 11 protects the position of the injection pipe 13 to a certain extent, preventing positional interference between the injection pipe 13 and adjacent rectangles. During installation, the injection pipe 13 is located within the clearance groove 11 and can be connected to an external connecting pipe. Phase change fluid is injected into the receiving cavity 17 within the shell 1 through the injection pipe 13. The injection pipe 13 can be threaded into the external connecting pipe, allowing the phase change fluid to flow smoothly into the receiving cavity 17.

[0037] Fasteners 15 (such as bolts) are threaded into the first threaded hole 14 and the second threaded hole, allowing the shell 1 to be stably installed on the inner wall of the container and facilitating disassembly. At the same time, the design of the first threaded hole 14 does not affect the sealing performance of the shell 1's receiving cavity 17, because the first threaded hole 14 is manufactured using a molding process such as rectangular casting, which does not affect the cavity's sealing performance.

[0038] It should be noted that the bolts are made of the same material as the shell 1, which helps to improve the durability and stability of the entire insulation module and avoids loosening of the connection due to the different expansion coefficients of different materials.

[0039] In some embodiments, the shell 1 may also be other shapes that facilitate alignment and splicing.

[0040] The shell 1 has gripping holes 16 on its opposite sides that pass through it and are easy for people to grip.

[0041] The shell panel 1 has gripping holes 16 on opposite sides, which penetrate the panel and are easy for personnel to grasp, facilitating operation of the shell panel 1 during installation, disassembly, or maintenance. The gripping holes 16 provide a convenient gripping position, allowing installers to easily remove the shell panel 1 from the inner wall of the container or reinstall it. The gripping holes 16 are formed in a similar manner to the first threaded hole 14, typically through processes such as casting or molding.

[0042] The dimensions of the rectangle are 380*290*25mm.

[0043] The shell 1 is made of HDPE material, and the phase change fluid is a mixture of resin and nanocapsules.

[0044] The outer shell 1 is made of HDPE (high-density polyethylene). HDPE material has high chemical stability, excellent impact resistance, and good weather resistance, effectively resisting the corrosion of chemicals such as acids, alkalis, and salts in the environment. It also possesses strong mechanical strength, ensuring the long-term stability and durability of the outer shell 1. Due to the low density and good processability of HDPE, it not only provides the necessary structural support but also maintains a relatively light weight, making the insulation module more convenient to transport and install.

[0045] The phase change fluid is composed of a mixture of resin and alkane nanocapsules. The alkane nanocapsules are the main component of the liquid fluid, exhibiting good flowability and viscosity control, ensuring uniform distribution within the cavity 17 of the injection shell 1. The resin itself maintains a certain degree of flowability at low temperatures, and when needed, it can interact with the phase change material within the nanocapsules, absorbing and releasing energy through a phase change process. The mixture of resin and alkane nanocapsules forms a phase change fluid with high energy storage density. When the external temperature changes, the phase change material within the alkane nanocapsules undergoes a phase change, releasing or absorbing heat, effectively regulating the temperature control of the shell 1.

[0046] The phase transition point of the nanocapsules is 26℃ or 17℃, and the enthalpy of the nanocapsules is greater than 150 kJ / kg.

[0047] Depending on the ambient temperature, a suitable phase change point is selected to achieve optimal temperature control. For example, when the ambient temperature is 5-10℃, a nanocapsule material with a phase change point of 26℃ is chosen. In this case, after the insulation module of the nanocapsules with a phase change point of 26℃ is preheated and placed in the medical cabin, these phase change materials will release the stored heat over the next 180 minutes, maintaining the cabin temperature within a suitable range of 18-25℃, ensuring that medical equipment, medicines, etc., are kept within a safe temperature range.

[0048] When the ambient temperature is 30-35℃, nanocapsule materials with a phase change point of 17℃ are selected. Under these conditions, the insulation module of the nanocapsules with a phase change point of 17℃ is cooled. After the pre-cooled insulation module is placed into the medical cabin, these phase change materials can maintain the cabin temperature stable between 18-25℃ for the next 180 minutes, preventing the cabin temperature from becoming too high.

[0049] This application also discloses a mobile medical cabin, wherein the inner wall of the mobile medical cabin 2 is connected with the heat preservation module as described above.

[0050] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0051] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
