Abstract
DESCRIPTION (provided by applicant): People who use wheelchairs (clients), caregivers, and professional staff have identified the need for a lift device to help people in wheelchairs, who cannot or have difficulty transferring independently, transfer from a wheelchair into and out of a bathtub. LifterMate is an assistive transfer device that will help clients and caregivers transfer more easily from wheelchair to bed to toilet to bathtub. Currently available commercial lift devices become unstable as the cl ient is moved outside the dimensions of the base. LifterMate incorporates an innovative stabilizing design that allows the movement of the client in three dimensions, which will allow movement into and out of a bathtub, onto and off the floor, as well as o nto and off a bed under which there is no room for the base of current lifters. Current options for tub transfers require major installation or permanent renovation. LifterMate is relatively inexpensive, easily maneuvered from room to room, easily installe d for single or multiple transfers, easily removed and relocated to new facilities, and appropriate for short or long- term use. Two design concepts for the stabilizer component will be evaluated in Phase I to demonstrate feasibility. Focus groups of stake holders-clients, caregivers, and professional staff-will provide guidance on their concerns and issues on the usability of lifters, evaluate design drawings, and then evaluate full-scale models of the two designs. Bench models of the two stabilizer designs will be prepared incorporating the stakeholder feedback. Engineering analyses of the bench models will be conducted and their ability to move a 113 kg human dummy in a path simulating a transfer from a wheelchair into and out of a bathtub determined. Feas ibility requires both stakeholder and engineering support for one or both stabilizer designs. Phase II will focus on the development of prototypes of the stabilizers and the evaluation of the units with human subjects, including, once safety has been demon strated, clients. It will also include the design, development and evaluation of the arm and base components as well as their integration with the stabilizers. The preparation and evaluation of full LifterMate prototypes will complete Phase II and precede Phase III commercialization. Project Relevance The LifterMate, developed by Criterion Health, Inc., will provide a low-tech solution to a serious and often costly problem for individuals in wheelchairs, who cannot or have difficulty transferring independen tly, and their caregivers. The Hoyer Lift, which has remained virtually unchanged since its 1958 patent and Hoyer-style lifts are commonly used to perform basic transfers, but they are not able to transfer people in and out of the tub, or lift a person fro m the floor. Both of these transfers are common in everyday living and can cause serious injury to the caregiver or patient if not done properly. The LifterMate will improve the quality of life for both caregivers and patients with a creative solution to a challenge of daily functioning for people with disabilities and their families.
