介绍了一种新型膝关节免载矫形器,其可以在下肢伸展时通过大腿托向上牵拉膝关节以承担部分载荷。为了增强其免载荷能力,采用在大腿托与皮肤接触的表面上增加硅胶防滑凸起的改进方法。利用传感器、蓝牙无线通信模块以及LabVIEW搭建了一套实时无线温湿度监测系统,记录大腿托所覆盖皮肤表面的温湿度随时间变化的趋势,并分析在环境温度较高时不同密度的防滑凸起对皮肤表面温湿度的影响程度。结果显示,温度较高时越密的防滑凸起对皮肤散热透气的阻碍越大,湿热舒适性越差,且越容易造成出汗打滑的现象。
A new knee-free orthotic device is introduced which can pull the knee upwards through the thigh support for partial load as the lower limb is extended. In order to enhance its load-free ability, an improved method of adding silicone anti-slip protrusions on the surface of the thigh support in contact with the skin is adopted. A set of real-time wireless temperature and humidity monitoring system was set up with sensors, Bluetooth wireless communication module and LabVIEW to record the trend of the temperature and humidity over the skin covered by the thigh caretakers over time, and analyzed the different density of anti-skid bulge The degree of influence on the temperature and humidity of the skin surface. The results showed that the higher the temperature is, the more dense the non-slip protrusions on the ventilation of the skin the greater the impediment, the worse the comfort of hot and humid, and the more likely to cause sweating and skidding phenomenon.
