DETAILED DESCRIPTION

[0020] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] Figure 1 The internal structure diagram of the deep vein cold and hot compress leg physiotherapy device provided by the present invention is as follows: Figure 1 As shown, the deep vein hot and cold compress leg physiotherapy device includes a hot and cold compress bag 1, a suction pump module 2, an electromagnetic switch module 3, a temperature sensor module 4, a heating device module 5, a refrigeration device module 6, a display module 7, a power module 8, a single-chip computer module 9 and a catheter 10.

[0022] The hot and cold compress bag 1 has four liquid inlets 101 and four liquid outlets 102. Pressure blocks 103 and retractable massage points 104 are provided on the inner surface of the hot and cold compress bag 1 at positions corresponding to leg acupuncture points such as Chengshan, Zusanli, and Weizhong, and magnetic therapy and massage can be selectively performed on leg acupuncture points. According to the massage intensity and massage time set by the user on the touch screen, the magnetic field intensity is adjusted through the PWM function of the single-chip microcomputer module 9STM32. When the massage time is met, the PWM duty cycle is set to 0, and the pressure block 103 stops working.

[0023] When the hot / cold pack 1 is filled with liquid, Figure 2 As shown, the massage points will be protruded, and when the liquid in the hot or cold compress bag 1 is discharged, the massage points will shrink, and the massage of the corresponding acupuncture points can be achieved by repeating the cycle.

[0024] Figure 3 A schematic diagram of a leg wrapping device for deep vein cold and hot compress leg physiotherapy provided by the present invention, Figure 4 This is a schematic diagram of the detection system structure of the deep vein hot and cold compress leg therapy device provided by the present invention.

[0025] An electromagnetic switch is connected to each liquid inlet and outlet 102 of the cold and hot compress bag 1, and the four liquid inlets 101 are combined into a conduit 10 after passing through the electromagnetic switch, and the four liquid outlets 102 are combined into a conduit 10 after passing through the electromagnetic switch. The electromagnetic switch is used to cooperate with the liquid suction pump module 2 to transport liquid to the cold and hot compress bag 1. The opening and closing of the electromagnetic switch is controlled by outputting a signal through an IO port of the STM32. When the electromagnetic switch of the liquid outlet 102 is turned on, the liquid suction pump is turned on, and the liquid in the cold and hot compress bag 1 is discharged; when the electromagnetic switch of the liquid inlet 101 is turned on, the liquid suction pump is turned on, and the liquid is transported to the cold and hot compress bag 1; thereby realizing the self-circulation of the liquid in the cold and hot compress bag 1.

[0026] The temperature sensor module 4 is connected to the catheter 10 where all the liquid outlets 102 of the cold or hot compress bag 1 are combined, and is used to measure the temperature of the liquid in the catheter 10 .

[0027] One end of the heating device module 5 and the cooling device module 6 are connected to the temperature sensor, and the other end is connected to the liquid suction pump module 2. It is used to heat or cool the liquid before delivering it to the hot and cold compress bag 1, so as to control the liquid temperature in the hose at 5°C-40°C. The PWM output function of the STM32 timer is used in combination with the PID algorithm to compare the difference between the temperature measured by the temperature sensor and the set temperature. If the measured temperature is lower than the set temperature, the heating device is turned on, and the specific operating time is dynamically adjusted after the PID algorithm is calculated; similarly, if the measured temperature is higher than the set temperature, the cooling device is turned on, and the specific operating time is dynamically adjusted after the PID algorithm is calculated.

[0028] One end of the suction pump module 2 is connected to the temperature sensor module 4, and the other end is connected to the catheter 10 after all the liquid inlets 101 of the cold and hot compress bag 1 are combined, and is used to cooperate with the electromagnetic switch pump module to realize the liquid self-circulation of the cold and hot compress bag 1. When the device is running, the STM32 drives the suction pump to work through the motor driver board. Its main principle is to use the PWM output function of the STM32 timer to control the start and stop of the suction pump. The electromagnetic switch of the liquid outlet 102 is turned on, the suction pump is turned on, and the liquid in the cold and hot compress bag 1 is discharged; the electromagnetic switch of the liquid inlet 101 is turned on, the suction pump is turned on, and the liquid is transported to the cold and hot compress bag 1; adjust the drainage time, the liquid inlet time, and the interval between the two, so as to control the massage intensity and frequency.

[0029] The display device is used for users to start and stop the device, select massage mode, massage intensity, temperature and duration, and display information such as temperature and massage duration in real time. STM32 is connected to the touch screen and FSMC technology is used to realize data transmission. LVGL is used to build a GUI interface to achieve simplicity and ease of operation of the human-computer interaction interface.

[0030] The power module 8 is used to supply power to other modules.

[0031] The single chip computer module 9 is used to receive temperature value information from the temperature sensor module 4 and the touch screen module, and send control signals to the liquid suction pump module 2, the electromagnetic switch module 3, the heating device module 5, and the refrigeration device module 6 according to the set value.
