A lifting mechanism for invalid patients, confined to wheel chairs is disclosed. The device is integrally connected to the wheelchair rather than being fixed in one place. This permits the patient to be moved within a home, doctor's office or hospital without having to bring the patient to such a fixed-in-place lifting device. The invention uses an outrigger support to ensure stability of the wheel chair while the device is in operation. The device is typically powered by the battery commonly found on self propelled wheelchairs. Of course, for manual wheelchairs, a battery can be installed if needed. The device uses a sling to cradle the patient. The sling is attached to a lifting bar, which is placed at the end of the lift cable. A motor is used to retract or extend the cable as needed and to lift and hold the patient. The patient is lifted to a safe height above the chair, and the motor is slid along a track to the end of a cantilever beam. The patient can then be lowered to a bed, jacuzzi, or other treatment facility as needed. To return the patient to the wheelchair, the reverse procedure is employed. The device is designed to disassemble for travel in vans or airplanes.
