Abstract: A manually-activated reduced pressure treatment system includes a substantially rigid housing, and an end cap slidingly received by the housing. An inner chamber is disposed between the end cap and housing, and a volume of the inner chamber is variable in amount depending on the position of the end cap within the housing. The end cap is slidingly movable between an uncompressed position at which the volume of the inner chamber is at a maximum value and a compressed position at which the volume of the inner chamber is at a minimum value. A position indicating member is associated with the end cap and housing to indicate the position of the end cap relative to the housing at predetermined positions between the uncompressed position and the compressed position.

Abstract: The present invention provides a therapeutic bed which comprises:(a) a trolley frame (1) having floor-engaging feet or wheels (2),(b) an attitude frame (3) pivotably mounted on the trolley frame so as to be pivotable through a predetermined arc about an axis extending longitudinally of the bed,(c) operating means (62, 67 & 64) for causing the attitude frame to pivot in one direction and then the other through said predetermined arc,(d) a plurality of air sacs (14) supported on said attitude frame and inflatable to a pressure sufficient to provide a resilient surface for supporting a patient thereon, said air sacs together forming a shaped cavity (31, 32, 33) within which the patient's body can be nested and supported so that the patient does not slide off the bed during turning, and(e) microprocessor control means for causing the turning movement of the attitude frame to be arrested when reaching the end of the predetermined movement in one direction and causing the operating means to reverse the direction of
