ABSTRACT:
A patient lift system incorporates a transverse bar which carries a patient lift system for movement between two laterally extending bars. The transverse bar is mounted at the same vertical height as the laterally extending bars and carries a motor for lifting and lowering the patient. Since the transverse bar is at the same vertical height additional patient lift height is provided as compared to prior art systems. In a further feature of the present invention, the frame includes an improved corner bracket and also includes vertical adjustment for the legs to achieve leveling of the overall frame. In another feature of this invention, a patient lift bar includes four lift points, with two forward lift points spaced by a greater distance than the two rearward lift points. This provides greater support to the rear of the patient, while the additional distance in the front facilitates entry and removal of the patient lift system. In addition, an inventive sling provides a support for attachment to the lift bar which comfortably lifts the patient. In other aspects of this invention, a solid state motor control allows easy control of the speed of the motor for the patient lift system. In other features, the motor control incorporates a remote control that receives a low voltage and current such that the remote control is relatively safe to use. In a second embodiment sling, a head portion supports the patient's head, and is to the rear lift points described above. Other improvements are disclosed in the application.
