Abstract

The present invention provides an adjustable fixed-point temperature-controlled external fixation device for lower limbs, which includes: setting the temperature of the cold compress through buttons, starting the refrigeration sheet, and the refrigeration sheet works; the sensor transmits the cooling temperature of the refrigeration sheet to the MCU through the sensor, and the MCU makes a response adjustment The voltage of the cooling plate, the pressure sensor transmits the pressure at this time to the MCU, and the MCU displays the pressure value through the OLED. Input the preset temperature value through the liquid crystal display and the key input module, and the collected voltage value is fed back to the single-chip microcomputer. After A / D conversion, the single-chip microcomputer compares the collected temperature value with the preset temperature value and judges it. Through PID calculation, it outputs PWM pulse modulation signal to the drive circuit, and then controls the heating and cooling capacity of the semiconductor refrigeration and the switching of the heating and cooling direction. The air inside the air cushion on the device is signaled by the MCU to the solenoid valve to change the state of the solenoid valve for selective inflation and deflation.

Description

technical field [0001] The invention relates to the technical field of medical surgical devices, in particular to an adjustable fixed-point temperature-controlled external fixation device for lower limbs. Background technique [0002] Ice and snow sports are a kind of world-wide sports with various forms, rich content, entertainment and fitness. Although compared with northern Europe, North America and other countries, domestic ice and snow sports are not hot enough. Although ice and snow sports are uniquely attractive, we should also pay attention to the possible sports injuries. Due to its fast speed, high intensity, and unstable motion plane, its risk factor is no less than that of strong confrontation sports such as Sanda and boxing. Sports injuries are also different from common injuries. Due to the venue of ice and snow sports, the rescue after injury is also different from the treatment of ordinary sports injuries. Therefore, we design the treatment with the characte...
