Abstract
A compact, lightweight, power lifting unit assists the operator of a mobile patient transporter in raising or lowering the patient bed to the desired height required in transporting or transferring a patient. The power lifting unit may also be used to 'collapse' the transporter to its lowest height. The power lifting unit is adaptable and may be installed on virtually any existing 'X' frame transporter. Electronic controls allow a single operator to raise or lower the patient bed or allow the patient bed to coast gently to a rest position. In particular, in one embodiment the power lifting unit includes a jog pulse circuit that prevents operators from jamming the transporter. In another embodiment, the power lifting unit includes a jog-off high limit circuit that prevents operators from attempting to raise the transporter beyond its maximum height. In yet another embodiment, a power lifting unit includes a low battery detection circuit that provides both an audible and a physical indication (i.e., a pulsating response) to operators of a low battery condition (i.e., when battery voltage decreases below a predetermined level).
