All manual lifting and repositioning techniques have a high-risk for injury to caregivers. Work-related back pain and injuries are a widespread epidemic and due in large part to repeated patient handling activities, including lifting, transferring, and repositioning tasks. Bed to chair and chair to toilet transfers are consistently ranked among the most physically stressful tasks required of patients and caregivers. Mechanical transfer assist devices were found to reduce the risk of injury to caregivers. Consequently, the United States (US) government passed a bill in 2006 requiring all hospitals to establish a no manual lift policy for staff members who interact directly with patients to reduce the risk of work-related musculoskeletal disorders. The most commonly used lift technologies for dependent transfers of patients include the overhead ceiling lift, the floor-based sling lift, and the Gantry lift. While these devices allow for safer transfer of patients, they do so with shortcomings. Overhead sling lifts require extensive installation that may not be suitable for homes or buildings with structural deficiencies or a low ceiling. Floor-based sling lifts have several issues with caregiver manipulation and ease of use. Gantry lifts are very difficult to move and store due to their size. Research has demonstrated that people with mobility impairments and caregivers both desire new, powered devices for safer and more comfortable and independent transfers. The AgileLife Patient Transfer and Movement System (PTS) developed and commercially deployed by Next Health LLC is an integration of several assistive technologies that together automate the transfer of immobile individuals to and from a hospital bed and a wheelchair. The PTS includes a hospital bed, an integrated and detachable wheelchair/commode chair, a docking system, and a transfer ‘sheet’ that moves the individual to and from the bed. However, the existing PTS has not been designed to work with a power wheelchair. The goals of this project will be to iteratively design, prototype and test a modified PTS and group 3 power wheelchair so that the PTS and power wheelchairs could be compatible, allowing it to be used by a greater number of people with physical disabilities. This will be accomplished by refining design specifications with a focus group of end user including group 3 wheelchair users and caregivers. Then developing a prototype and testing it for functionality and safety. User testing will then be conducted by having group 3 wheelchair users and caregiver pairs trial the prototype and complete usability questionnaires. A physical therapist will also rate the safety of the transfers during the user testing.

所有手动提升和重新定位技术都有对护理人员造成伤害的高风险。 与工作相关的背痛和伤害是一种普遍存在的流行病，很大程度上是由于 重复患者搬运活动，包括举起、转移和重新定位任务。床到 椅子和椅子到厕所的转移一直被列为身体压力最大的事情之一 患者和护理人员所需的任务。机械转移辅助装置被发现 降低护理人员受伤的风险。因此，美国（US）政府 2006年通过一项法案，要求所有医院为工作人员制定无手动电梯政策 他们直接与患者互动，以降低与工作相关的肌肉骨骼疾病的风险。 用于患者转移的最常用移位技术包括 天花板式升降机、地面吊索式升降机和龙门式升降机。虽然这些设备允许 虽然为了更安全地转移病人，他们这样做也有缺点。高架吊索升降机需要大量 可能不适合结构缺陷或低矮的住宅或建筑物的安装 天花板。地面吊索移位机在护理人员操作和易用性方面存在一些问题。 龙门式升降机由于其尺寸而非常难以移动和存放。研究表明 行动不便的人和护理人员都渴望新的电动设备 更安全、更舒适、更独立的接送服务。 AgileLife 患者转移和移动系统 (PTS) 开发并 Next Health LLC 的商业部署是多种辅助技术的集成 一起自动将无法移动的人员转移到医院病床和从医院病床转移出来 轮椅。 PTS 包括一张病床、一个集成的、可拆卸的 轮椅/马桶椅、对接系统以及将个人移动到的转移“床单” 并从床上。然而，现有的 PTS 并未设计为与电源一起工作。 轮椅。 该项目的目标是迭代设计、原型化和测试修改后的 PTS 和第 3 组电动轮椅，以便 PTS 和电动轮椅兼容， 让更多的身体残疾人士能够使用它。这将是 通过与最终用户焦点小组（包括第 3 组）完善设计规范来完成 轮椅使用者和护理人员。然后开发原型并测试其功能和 安全。然后由第 3 组轮椅使用者和护理人员进行用户测试 两人一组试用原型并完成可用性调查问卷。物理治疗师也会评价 用户测试期间传输的安全性。
