Description

Wearable skin temperature control and heat dissipation device and method Technical Field

[0001] The present invention relates to the technical field of physiological indicator monitoring, and in particular to a wearable skin temperature control and heat dissipation device and method, and a human health detection system and method. Background Art

[0002] In recent years, with rising public awareness of health and the rapid development of medical technology, smart health monitoring devices have become an integral part of people's lives. From oximeters and blood pressure monitors to heart rate monitors, these multifunctional devices provide individuals with real-time health data in their daily lives. Through these devices, people can conveniently monitor physiological indicators such as blood oxygen, blood pressure, blood sugar, and heart rate, gaining real-time insights into their health and enabling them to take timely health management measures. They also provide important diagnostic evidence for medical professionals.

[0003] However, the accuracy and reliability of these smart health monitoring devices are often affected by ambient temperature. Physical movement and activity can cause a transient increase in body temperature, especially after strenuous exercise. This can lead to errors in the recording and interpretation of temperature changes by smart health monitoring devices, thus affecting the accuracy of the data.

[0004] To address these issues, a wearable skin temperature control and heat dissipation device has been added to the existing photoelectric physiological indicator detection equipment. Through precise temperature control technology, the wearable skin temperature control and heat dissipation device can provide a stable operating temperature range for health testing, ensuring the accuracy of data collection.

[0005] However, the heat dissipation methods of these wearable skin temperature control and heat dissipation devices are unsatisfactory. Some wearable skin temperature control and heat dissipation devices do not add additional heat dissipation modules, and dissipate the heat of the wearable skin temperature control and heat dissipation devices into the air. However, this method has very low heat dissipation efficiency and is very easy to damage the wearable skin temperature control and heat dissipation devices when working for a long time. Some wearable skin temperature control and heat dissipation devices dissipate heat by adding cooling fans, but the cooling fans generate noise when running, which is considered to be disturbing and uncomfortable in medical treatment. In addition, the cooling fans are relatively large, which may pose a challenge in some lightweight or small devices.

[0006] Currently, no effective solutions have been proposed to address the problems of low heat dissipation efficiency, large size due to the use of cooling fans, and high heat dissipation noise in wearable skin temperature control and heat dissipation devices in related technologies.

[0180] Example 4

[0181] This embodiment relates to a specific implementation of the wearable skin temperature control and heat dissipation device of the present invention.

[0182] As shown in Figures 9 to 11, a wearable skin temperature control and heat dissipation device according to one embodiment of the present invention includes a heat-conducting metal sheet 1A, a semiconductor cooling sheet 1B, a heating metal sheet 1C, a heat-conducting layer 2B, and a control module. Heat-conducting layer 2B is disposed between heat-conducting metal sheet 1A and semiconductor cooling sheet 2B, and between heating metal sheet 1C and semiconductor cooling sheet 1B.

[0183] The semiconductor refrigeration sheet 1B achieves heat transfer and temperature difference through the Peltier effect. In cooling / heating mode, the semiconductor refrigeration sheet 1B cools / heats the human skin through the heating metal sheet 1C, and the semiconductor refrigeration sheet 1B dissipates heat / cools through the heat-conducting metal sheet 1A.

[0184] The heat-conducting metal sheet 1A is mainly used to dissipate heat for the semiconductor cooling sheet 1B to increase the stability of the semiconductor cooling sheet 1B.

[0185] Generally, the material of the heat-conducting metal sheet 1A is not limited, and is preferably copper, but other materials with good thermal conductivity may also be used.

[0186] Generally, the material of the semiconductor refrigeration plate 1B is not limited, and is preferably a bismuth selenide semiconductor material, and other materials with good thermoelectric properties can also be used.

[0187] The heating metal sheet 1C is mainly used to heat or cool human skin.

[0188] Generally, the material of the heating metal sheet 1C is not limited, and is preferably a copper sheet, but other materials with good thermal conductivity may also be used.

[0189] The heat-conducting layer 2B is used to transfer heat between the heat-conducting metal sheet 1A, the semiconductor cooling sheet 1B, and the heating metal sheet 1C.

[0190] Generally, the material of the heat-conducting layer 2B is not limited, and is preferably thermal grease (mainly composed of silicone oil, silicon oxide, stabilizer and additives). Other materials with good thermal conductivity can also be used.

[0191] The control module includes a control circuit 3A, a power module 3B, a driver module 3C, and a temperature detection module 3D. The power module 3B is connected to the control circuit 3A for power supply. The driver module 3C is connected to the control circuit 3A and the semiconductor cooling plate 1B, respectively, to apply forward and reverse voltages to the semiconductor cooling plate 1B under the control of the control circuit 3A. The temperature detection module 3D is connected to the control circuit 3A for detecting human skin temperature and the temperature of the heating metal plate 1C.

[0192] Furthermore, the control module also includes a storage module. The storage module is connected to the control circuit 3A and is used to store a temperature control algorithm to dynamically adjust the output power of the semiconductor cooling plate 1B. Generally, the temperature control algorithm is a PID algorithm.

[0193] The method of using this embodiment is as follows:

[0194] Set a temperature value T1 and place the wearable skin temperature control and heat dissipation device on the skin. If the skin temperature T2>T1 at this time, the cooling mode is turned on, otherwise the heating mode is turned on.

[0195] In cooling mode, the control module applies a forward bias to the semiconductor cooling chip 1B. One side of the heating metal sheet 1C is connected to the cold surface of the semiconductor cooling chip 1B via the thermally conductive layer 2B, while the other side can be connected to the surface of human skin 2A. Due to the heat conduction effect, the cold surface of the semiconductor cooling chip 1B absorbs heat from the surface of human skin 2A, thereby cooling the skin locally. One side of the thermally conductive metal sheet 1A is connected to the hot surface of the semiconductor cooling chip 1B via the thermally conductive layer 2B, while the other side can be connected to human skin 2A. Due to the heat conduction effect, the hot surface of the semiconductor cooling chip 1B dissipates heat to the skin 2A, thereby dissipating heat from the semiconductor cooling chip 1B.

[0196] In heating mode, the control module applies a reverse bias to the semiconductor cooler 1B. One side of the heating metal sheet 1C is connected to the hot side of the semiconductor cooler 1B via the thermally conductive layer 2B, and the other side can be connected to the surface of human skin 2A. Due to the heat conduction effect, the hot side of the semiconductor cooler 1B will dissipate heat to the surface of human skin 2A, thereby warming the skin locally. One side of the thermally conductive metal sheet 1A is connected to the cold side of the semiconductor cooler 1B via the thermally conductive layer 2B, and the other side can be connected to human skin 2A. Due to the heat conduction effect, the cold side of the semiconductor cooler 1B will transfer heat from the human skin 2A to the semiconductor cooler 1B, thereby equalizing the heat.

[0197] The control module includes a temperature detection module 3D, which can detect the temperature of the heating metal plate 1C and call the temperature control algorithm of the built-in storage module to dynamically adjust the output power of the semiconductor refrigeration plate 1B to maintain the local skin temperature of the human body stable at the preset temperature value T1.
