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 client 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 onto 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 installed 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 stakeholders-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. Feasibility 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 demonstrated, 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 independently, 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 from 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.

描述（由申请人提供）：使用轮椅的人（客户），护理人员和专业工作人员已经确定需要一个升降装置来帮助轮椅上的人，他们不能或难以独立转移，从轮椅转移到浴缸中。LifterMate是一种辅助转移设备，将帮助客户和护理人员更容易地从轮椅转移到床上，厕所到浴缸。当前可用的商用升降机装置在客户移动到基座的尺寸之外时变得不稳定。LifterMate采用了创新的稳定设计，允许客户在三维空间内移动，这将允许移动进出浴缸，上和下的地板，以及上和下的床，其中没有空间的基础目前升降机。目前的浴缸转移选择需要重大安装或永久性翻新。LifterMate相对便宜，很容易从一个房间到另一个房间，很容易安装单次或多次转移，很容易拆卸和搬迁到新的设施，适合短期或长期使用。稳定器部件的两个设计概念将在第一阶段进行评估，以证明其可行性。焦点小组的患者，客户，护理人员和专业人员将提供指导，他们的关注和问题的可用性升降机，评估设计图纸，然后评估两个设计的全尺寸模型。两种稳定器设计的台架模型将结合利益相关者的反馈意见进行准备。将对台架模型进行工程分析，并确定其在模拟从轮椅进出浴缸的路径中移动113 kg人体假人的能力。可行性要求利益相关者和工程支持的一个或两个稳定器的设计。第二阶段将侧重于稳定器原型的开发，以及对人体受试者（一旦安全性得到证明，包括客户）的单位进行评估。它还将包括臂和基座组件的设计、开发和评估，以及它们与稳定器的集成。完整LifterMate原型的准备和评估将完成第二阶段，并在第三阶段商业化之前完成。项目相关性LifterMate，由标准健康公司开发，将为坐轮椅的人及其护理人员提供一种低技术解决方案，解决一个严重且往往昂贵的问题，这些人不能或难以独立转移。自1958年获得专利以来，Hoyer Lift几乎保持不变，Hoyer式升降机通常用于执行基本转移，但它们不能将人转移到浴缸内外，也不能将人从地板上抬起。这两种转移在日常生活中很常见，如果操作不当，可能会对护理人员或患者造成严重伤害。LifterMate将改善护理人员和患者的生活质量，为残疾人及其家人的日常功能挑战提供创造性的解决方案。
