Abstract：
UNASSIGNED: Pressure ulcers (PUs) are prevalent among immobile bed or wheelchair-reliant individuals who experience prolonged sedentary positions. Pressure relief and frequent repositioning of body posture help to mitigate complications associated with PUs. Adherence with regular repositioning is difficult to maintain due to nursing labour shortages or constraints of in-home caregivers. Manual repositioning, transferring, and lifting of immobile patients are physically demanding tasks for caregivers. This review aimed to explore and categorize these devices, discuss the significant technical challenges that need addressing, and identify potential design opportunities.
UNASSIGNED: In this review, a literature search was conducted using PubMED, Science Direct, Google Scholar and IEEE Xplore databases including studies from 1995 until Feb 2023 with keywords such as pressure ulcer, assistive device, pressure relief, repositioning, transfer, etc. Both commercial and research-level devices were included in the search.
UNASSIGNED: 142 devices or technologies were identified and classified into four main categories that were further subcategorized. Within each category, the devices were investigated in terms of their mechanical design, actuation methods, control strategies, sensing technologies, and level of autonomy. Limitations of current technologies are design complexity, lack of patient comfort, and a lack of autonomy requiring caregivers frequent intervention.
UNASSIGNED: Several devices have been developed to help with prevention and mitigation of PUs. There remain challenges that hinder the widespread accessibility and use of current technologies. Advancements in assistive technologies for pressure ulcer mitigation could lie at the intersection of robotics, sensors, perception, user-centered design, and autonomous systems.
Future advancements in assistive technologies for pressure ulcer mitigation could lie at the intersection of robotics, sensors, perception, user-centered design, and autonomous systems.Most existing technologies for prevention of pressure ulcers are focused on the mechanical advantage rather than user’s needs and preferences. Future designers, engineers, and product developers must be educated to conduct user needs studies concurrently with the development of technology to design the devices based on the user’s needs to ensure a balanced design outcome.

摘要：
■压力性溃疡（PU）在长期久坐不动的卧床或轮椅依赖者中普遍存在。压力释放和身体姿势的频繁重新定位有助于减轻与PU相关的并发症。由于护理劳动力短缺或家庭护理人员的限制，很难维持定期重新定位的坚持。手动重新定位,转移,对于护理人员来说，解除不动的病人是一项要求很高的身体任务。这篇综述旨在探索和分类这些设备，讨论需要解决的重大技术挑战，并确定潜在的设计机会。
■在这篇评论中，使用PubMED进行文献检索，科学直接，GoogleScholar和IEEEXplore数据库，包括1995年至2023年2月的研究，关键字包括压疮，辅助装置,泄压,重新定位,转让,等。搜索中包括商业和研究级设备。
■对142种设备或技术进行了识别，并将其分为四个主要类别，并进一步细分。在每个类别中，这些设备根据其机械设计进行了研究，驱动方法，控制策略,传感技术，和自治水平。当前技术的局限性是设计复杂性，缺乏患者的舒适感，缺乏自主性，需要护理人员频繁干预。
■已经开发了几种设备来帮助预防和缓解PU。仍然存在阻碍当前技术的广泛获取和使用的挑战。缓解压疮的辅助技术的进步可能在于机器人技术的交叉点，传感器,感知，以用户为中心的设计，和自治系统。对康复的影响未来缓解压力性溃疡的辅助技术的进步可能在于机器人技术的交叉点，传感器,感知，以用户为中心的设计，和自治系统。大多数预防压疮的现有技术都集中在机械优势上，而不是用户的需求和偏好。未来的设计师，工程师,产品开发人员必须接受教育，在技术发展的同时进行用户需求研究，根据用户的需求设计设备，以确保平衡的设计结果。
