Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a medical device case for use in high-temperature environments. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body. Their efficacy is mainly obtained through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role.

[0003] Excessive temperature can cause problems such as material degradation, chemical decomposition, reduced battery life, and electrostatic interference in medical devices. Therefore, medical devices need to be kept within a reasonable temperature range during logistics, distribution, and storage.

[0004] Existing medical device incubators use complex heating and cooling devices for temperature control, which not only has a complex structure but also makes electronic components prone to damage, requiring regular maintenance. Summary of the Invention

[0005] The purpose of this invention is to provide a medical device box for high-temperature environments that can achieve a cooling effect with only a simple structure, thus reducing structural complexity.

[0006] A medical device case for high-temperature environments includes: an inner shell, an outer shell, a temperature sensor, a controller, and a top cover; The inner housing is disposed within the outer housing; the upper cover is used to cover the inner housing and the outer housing; a medical device is placed inside the inner housing; Both the temperature sensor and the controller are disposed inside the inner housing; the temperature sensor is used to acquire the temperature value inside the inner housing in real time and send it to the controller. A heat dissipation cavity is provided between the outer shell and the inner shell; a plurality of heat conduction grooves are provided on the bottom surface of the outer shell; Each outer wall of the inner shell is provided with a heat dissipation structure; the heat dissipation structure is located inside the heat dissipation cavity. The heat dissipation structure includes a fan and several heat dissipation fins; the heat dissipation fins are aligned with the heat conduction groove; The outer casing has several ventilation openings on its side wall; the heat conduction groove is connected to the outside through the ventilation openings.

[0007] Optionally, both the inner shell and the outer shell are provided with sealing strips at their upper ends.

[0008] Optionally, a plurality of ventilation windows are provided on the side wall of the outer casing; a waterproof and breathable membrane is provided at the ventilation windows.

[0009] Optionally, each of the ventilation openings is provided with a waterproof and breathable membrane.

[0010] Optionally, an ultraviolet germicidal lamp is also provided inside the inner shell.

[0011] Optionally, the heat dissipation cavity is further provided with a plurality of shock-absorbing components; the inner shell and the outer shell are connected by the shock-absorbing components.

[0012] Optionally, the lower end of the outer casing is provided with a plurality of casters.

[0013] Optionally, a handrail is provided on the outer wall of the outer casing.

[0014] The effects of this invention are as follows: This invention relates to a medical device case for high-temperature environments. A temperature sensor acquires the internal temperature of the inner casing and sends it to a controller. When the temperature is below a set temperature, the fan shuts off, and passive cooling via heat sink fins meets the storage temperature requirements of the medical device. When the temperature exceeds the set temperature, the fan activates, with its exhaust direction perpendicular to the heat sink fins and aligned with the heat conduction channels. This achieves efficient heat dissipation through a combination of fin heat conduction and directional fan exhaust, ultimately removing heat through the ventilation openings. The fan alone is sufficient to achieve highly efficient heat dissipation, meeting the storage temperature requirements of the medical device. Attached Figure Description

[0017] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0018] Figure 1This invention relates to a medical device box structure for high-temperature environments. Figure 1 ; Figure 2 This invention relates to a medical device box structure for high-temperature environments. Figure 2 ,like Figure 1 and Figure 2 As shown, the present invention provides a medical device box for high-temperature environments, which includes: an inner shell 1, an outer shell 2, a temperature sensor, a controller, and a top cover 3.

[0019] Both the inner shell 1 and the outer shell 2 are hollow structures with openings at the top. The inner shell 1 is disposed inside the outer shell 2; the upper cover 3 is used to cover the inner shell 1 and the outer shell 2; the medical device is placed inside the inner shell 1. Specifically, the upper cover 3 is rotatably connected to the outer shell 2, and the upper cover 3 can rotate relative to the outer shell 2.

[0020] Preferably, in this embodiment, the outer shell 2 is made of high-strength ABS. Specifically, the interior of the inner shell 1 is divided into several accommodating cavities, each used to hold a medical device. Each accommodating cavity is equipped with a fixing bracket to secure the medical device and prevent it from sliding and causing damage.

[0021] Both the temperature sensor and the controller are housed within the inner casing 1; the temperature sensor is used to acquire the temperature value inside the inner casing 1 in real time and send it to the controller. In this embodiment, the temperature sensor is any one of a PT1000 platinum resistance thermometer, an NTC thermistor, and a digital temperature sensor.

[0022] like Figure 3 As shown, a heat dissipation cavity 4 is provided between the outer shell 2 and the inner shell 1; several heat conduction grooves 5 are provided on the bottom surface of the outer shell 2, such as... Figure 5 As shown. Specifically, the heat dissipation cavity 4 is formed by separating the four sides and bottom of the inner shell 1 from the outer shell 2 at a predetermined distance.

[0023] A heat dissipation structure is provided on each outer wall of the inner shell 1; the heat dissipation structure is located inside the heat dissipation cavity 4.

[0024] like Figure 4As shown, the heat dissipation structure includes a fan 6 and several heat dissipation fins 7; the heat dissipation fins 7 are aligned with the heat conduction grooves 5, that is, the gas flow direction of the heat dissipation fins 7 is towards the heat conduction grooves 5. The heat dissipation fins 7 are designed to increase the heat dissipation area, and the material of the heat dissipation fins 7 is aluminum alloy. Preferably, the fan 6 is a miniature silent fan. Specifically, each heat dissipation fin 7 is evenly distributed on the outer side wall of the inner shell 1, and each heat dissipation fin 7 is aligned with its corresponding heat conduction groove 5. Preferably, the heat dissipation structure has 10 heat dissipation fins 7, which are evenly arranged in three rows on the outer side wall of the inner shell 1. The first row has 3 heat dissipation fins 7, the second row has 4 heat dissipation fins 7, and the third row has 3 heat dissipation fins 7. The heat dissipation fins 7 in the first row and the second row are intersected in the vertical direction, and the heat dissipation fins 7 in the second row and the third row are intersected in the vertical direction.

[0025] Specifically, the heat dissipation fins 7 are elongated and connected to the outer wall of the inner shell 1, with a set angle between them so that the heat dissipation fins 7 are aligned with the heat conduction groove 5.

[0026] Several vents 8 are provided on the side wall of the outer casing 2; the heat conduction groove 5 is connected to the outside through the vents 8. The heat conduction groove enables the directional discharge of heat and avoids heat backflow.

[0027] Preferably, sealing strips are provided at the upper ends of both the inner shell 1 and the outer shell 2. The sealing strips are used to achieve a seal between the upper cover 3 and the inner shell 1, and between the upper cover 3 and the outer shell 2, thereby achieving heat insulation and preventing dust from entering.

[0028] Furthermore, several ventilation windows are provided on the side wall of the outer casing 2; a waterproof and breathable membrane is installed at each ventilation window. A waterproof and breathable membrane is also installed at each of the 8 ventilation openings. The dustproof rating of the waterproof and breathable membrane is IP54.

[0029] In order to achieve both heat preservation and sterilization of medical devices, an ultraviolet germicidal lamp is also installed inside the inner shell 1 to sterilize and disinfect the stored medicines and medical devices.

[0030] Preferably, a plurality of shock-absorbing components 9 are also provided inside the heat dissipation cavity 4; the inner shell 1 and the outer shell 2 are connected by the shock-absorbing components 9. Specifically, each corner of the four sides and the bottom of the inner shell 1 is connected to the outer shell 2 by the shock-absorbing components 9.

[0031] To facilitate the movement of the medical device case, several casters 10 are provided at the lower end of the outer shell 2. Handrails 11 are provided on the outer wall of the outer shell 2.

[0032] The specific principle of this invention is as follows: The installation of casters 10 and handles 11 facilitates the movement of the entire enclosure. A temperature sensor acquires the temperature value inside the inner shell 1. The controller judges the temperature value; when it is lower than the set temperature, the fan 6 is turned off. In this case, passive heat dissipation by the inner shell 1 itself and the heat sink 7, along with heat dissipation through the vents, is sufficient to meet the temperature requirements. When the temperature is greater than or equal to the set temperature, the fan 6 is turned on, blowing heat from the heat sink 7 into the heat conduction channel 5, and finally exhausting it through the vent 8, achieving active heat dissipation. In other words, this invention only requires a fan 6 to meet the heat dissipation needs, greatly reducing the complexity of the components.

[0033] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
