摘要

An apparatus for monitoring respiration and cardiac activity of a person lying in a bed comprises a bed mounted for polydirectional movement and subjected to a restoring force when the bed is disturbed from its normal position. Pulses originiating from the person are detected by a vertically oriented sensor and a pair of horizontally oriented sensors thereby permitting monitoring of a wide range of respiratory and cardiac activity. In one arrangement, the bed is suspended by cords or on a vertical frame from a bracket. In other arrangements, the bed is variously mounted on a gimbal mechanism, on a support column which passes through a bearing ball, by flotation, and by a universal bearing joint.
