ABSTRACT:
A convertible wheelchair is provided along with a separable lift module for engaging and elevating the convertible wheelchair to a selected elevation. A coupling assembly is operative associated with the lift module and adapted to extend therefrom to where the coupling assembly attaches to the convertible wheelchair. In one embodiment, the coupling assembly comprises a three-point attachment that results in the wheelchair being connected to the coupling assembly and hence the separable lift system at three points. Once coupled to the lift system, the convertible wheelchair, with a patient supported therein, can be raised to a selected elevation. Thereafter, the wheelchair can be converted from a chair configuration to any one of several examination configurations.
