为了减少因长时间坐在轮椅上而引起的压疮的风险，我们已经开发了一种用于轮椅使用者的减压运动辅助系统。我们开发的系统包括一个坐面升降装置和靠背张力协调装置。我们的系统有助于实现这两个设备的坐姿患者的适当姿势。在我们以前的工作中，我们通过分析长时间坐着的健康人的无意识身体运动来调查压疮风险的指数。根据这些分析结果，当受试者的姿势不合适时，受试者想要对他们的臀部或背部减压，并且压力集中到他们的臀部或背部上的特定位置持续固定的时间段。这些条件似乎是压疮风险的指标，在本文中，我们提出了一个自动减压运动辅助计划的基础上，这个指标。我们提出的系统帮助病人移动他的身体，以分散他的背部或背部的压力集中，并导致适当的坐姿时，这些条件得到满足。使用我们提出的辅助系统，病人可以通过自然的身体运动减压时，他想。我们的系统的性能进行了验证实验使用我们的原型。
For reducing the risk of pressure sore caused by long period sitting on a wheelchair, we have been developed a depressurization motion assistance system for a wheelchair user. Our developed system consists of a sitting surface lifting device and a backrest tension coordination device. Our system assists to realize the suitable posture of the seated patient with these two devices. In our previous works, we investigate an index of the pressure sore risk by analyzing unconscious body motions of a healthy person who sits long time. From these analysis results, subjects want to depressurize their buttock or back when their posture is not suitable and a pressure concentration to a specific position on their buttock or back continues the fixed period. These conditions seem to be an index of pressure sore risk and in this paper, we propose an automatic depressurization motion assistance scheme based on this index. Our proposed system assists a patient to move his body for distributing the pressure concentration on his buttock or back and leads the suitable sitting posture when these conditions are fulfilled. Using our proposed assistance system, the patient can depressurize by a natural body motion when he wants. The performance of our system is verified by experiments using our prototype.
