An air injection tube connects the body and the cuffs to transmit the compression air. Since the apparatus is capable to apply stimulation to several regions of the patient at the same time, the optimum stimulation is selected according to the feature of the patient.

Abstract: 본 발명은 전분을 이용한 펄프용기와 플라스틱등의 대체재료에 관한 것이다. 
     플라스틱, 합성수지등은 편리한 점도 있지만 공해물질배출등 그 폐해가 크다. 또 펄프용기등은 산림을 훼손하여 환경을 파괴시키는 주범이 되고 있다. 
     여기에 착안하여 전분과 천연수지와 인체에 해롭지 않는 합성수지를 혼합하여 고온합축하여 펄프용기와 플라스틱등의 대체재료로 사용한다. 천연재료를 사용하기 때문에 사용후에는 소각하거나 매립할 경우에도 환경오염을 일으키지 않는 환경친화적인 대체재료라 하겠다.
