Abstract
A cryotherapy system using cold air was developed. The developed system had superior low-temperature characteristics with various flow rates and nozzle sizes, and used R-404A, as a coolant, which has no destructive effects of Ozone layers. Flow rates and the treatment time can be easily altered during the operation. In addition, and alarm system was designed for the overload, overheat, and over-charge of the machine. For clinical applications, skin temperatures, intra-articular temperatures of the knee joint and intra-muscluar temperatures of the gluteal muscles were measured during and after the cryotherapy. After a 5-minute therapy, skin and intra-articular temperatures decreased by
신냉매인 R-404A를 사용하여 저온특성이 우수한 한냉물리치료기를 개발하였다. 임상평가를 통해서 침온도계를 슬관절 강 내 및 둔부근육 내에 삽입하여 직접 근육온도를 측정하였고, 적외선체열촬영기를 이용하여 표피온도를 객관적으로 측정하였다. 슬관절 부위에 대한 5분 동안의 한냉물리치료에 따른 표피 및 관절강 내 온도변화를 측정한 결과, 표피는 23.3
