Abstract
A patient lift for lifting and lowering a patient. Cable or rope may be used as the lifting element. The spool winds the lifting element in successive adjacent winds. The operator lifts the patient by pushing up on the carry bar, patient or lifting element, and lowers the patient by pushing down on such elements. The lift includes automatic loading and unloading for transition on or off the bed.
Claims13
A patient lift device for lifting and lowering a patient, the lift device comprising a motor assembly including a motor for generating lifting force, a harness for holding the patient, and a lifting element operatively connected to the motor and the harness, the motor assembly further comprising a spool operatively connected to the motor for winding and unwinding the lifting element to lift and lower the patient, the spool and lifting element being configured so that as the lifting element is wound on the spool, successive winds are positioned on the spool adjacent to one another.
A patient lift device for lifting and lowering a patient, the lift device comprising a motor assembly, a lifting element operatively connected to the motor assembly, and a harness operatively connected to the lifting element for holding the patient to be lifted and lowered, the lifting element and harness defining a load path along which a patient lift load is transmitted to the motor assembly, the device further including a load sensor along the load path configured to sense the load on the motor assembly, the device further including a controller, operatively connected to the load sensor and the motor assembly, for controlling the motor assembly, and for using an output from the sensor to cause the motor to lift the patient when an operator exerts an upward force on the patient or on the load path so as to reduce the sensed load, and to lower the patient when the operator exerts a downward force on the patient or on the load path so as to increase the sensed load.
