Abstract
A compensating valve and a drainage system for draining a body fluid from one body region to another body region. The system enables routine drainage at predetermined differential pressures, provides for pumping action, for flushing action to clear the system of obstructive material, and for resisting over-drainage which can occur when the patient makes an abrupt and relatively large change in his position. A compensating valve purpose has a valving action which is proportional to various parameters so as to enable continuous and proportional control for drainage rather than an on/off control.
