DOPPELT HYDRAULISCHES KRANKENHAUSBETT MIT UMGEHUNGSKREIS.

摘要

The bed has its head and thigh/leg elevation functions performed by hydraulic cylinders. A control circuit meters the introduction and removal of hydraulic fluid from the cylinders so an occupant of the bed is not subjected to any sudden movement. In case of an emergency requiring the bed occupant to be in a supine position, the normal control circuit is bypassed by an emergency circuit that allows much faster than normal lowering of the head and thigh/leg portions of the bed. A bed control panel is provided which includes a member of electrical switches for lighting, bed position and emergency control. In an emergency solenoid valves are used to quickly lower the bed portions.
