摘要

#CMT# #/CMT# Pneumatic control for pressurized air-driven decubitus system comprises a drive unit and a pneumatic valve system. The drive used is an electrically driven rotational motor (2) and is positively coupled with one or more pneumatic linear multiple-switch-over valves. #CMT#USE : #/CMT# For prevention of bed sores (decubitus ulcer) in patient having long-term bed confinement. #CMT#ADVANTAGE : #/CMT# Has complete valve system made air-tight in order to make do with the smallest possible air sealing unit. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# A side-view of a control device is given. 2 : Motor 3,4 : Fixture holders 5 : Shaft 6 : Eccentric movement 10 : Pressurized air supply cylinder.
