  • Patent number: 4247091
    Abstract: The same hospital bed may be employed for labor, delivery and recovery by providing two different adjustable back support sections in the mattress supporting structure. The expectant mother occupies the entire bed during labor and one back support, at the head end of the bed, may be tilted upward to raise the patient's back and head to maximize comfort. Prior to delivery, the patient is moved to the foot end of the bed and a second back support is tilted upward so that the patient will be held in a semi-sitting optimum position for delivery. The patient's legs may be held at a desired elevated level by a pair of crutches. In effect, the bed is convertible from a somewhat conventional hospital bed to an obstetrical table. After delivery, the second back support may be lowered so that the entire bed may then be used by the patient for recovery.
