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.

所有手动抬起和重新定位技术都有很高的伤害护理人员的风险。 与工作有关的背部疼痛和受伤是一种广泛的流行病，很大程度上是由于 重复病人处理活动，包括搬运、转移和重新定位任务。从床到床 椅子和椅子到厕所的转移一直是身体压力最大的之一 患者和照顾者需要完成的任务。发现机械转移辅助装置 减少照顾者受伤的风险。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建立无手动升降机政策 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。 最常用的移送病人的升降机技术包括 天花板升降机、落地吊索升降机和龙门升降机。虽然这些设备允许 更安全地转移病人，他们这样做是有缺点的。架空吊索升降机需要大量的 安装可能不适合结构有缺陷或较低的家庭或建筑物 天花板。落地式吊衣升降机在护理员的操作和易用性方面有几个问题。 由于龙门式升降机的大小，其移动和存储非常困难。研究表明， 行动不便的人和照顾者都想要新的动力设备 更安全、更舒适、更自主的换乘方式。 AgileLife患者转移和转移系统(PTS)开发并 由Next Health LLC商业部署的是几种辅助技术的集成 它们一起自动将不能移动的人转移到医院病床和医院 轮椅。PTS包括一张医院病床，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 从床上下来。然而，现有的临时技术秘书处的设计并不是为了与权力一起工作 轮椅。 该项目的目标将是迭代设计，原型和测试修改后的PTS 和第三组电动轮椅，以便PTS和电动轮椅可以兼容， 允许更多的肢体残疾人士使用它。这将是 通过与包括第三组在内的最终用户重点小组一起完善设计规范来完成 轮椅使用者和照顾者。然后开发一个原型并对其进行功能测试 安全。然后，将由第三组轮椅使用者和护理员进行用户测试 配对测试原型并完成可用性调查问卷。理疗师也会给你评分 在用户测试期间传输的安全性。
