项目摘要

This research consists of seven chapters. The 1st chapter clarified what ergonomic characteristics should be given to general care-taking devices and evaluated the importance of the sit-to-stand transfer device as a factor in supporting independent life. The 2nd chapter explained the response mechanism of circulatory physiology when standing up. In particular, it described measuring methods of autonomic nervous activity and cerebral circulation, both of which are necessary for physiological measurement when standing up. The 3rd chapter explained the characteristics of response of circulatory physiology when standing up and the occurrence mechanism of orthostatic hypotension (cerebral anemia) caused by such response, and then described the experiments conducted on the aged. The 4th chapter dealt with the theorization from the standpoint of circulatory physiology that the higher central nervous system plays an important role for the circulatory adjustment at the time of standing up. The 5th chapter evaluated the functions of the sit-to-stand transfer device, the seat of which is elevated and leaned forward with a button switch to help users stand up. The 6th chapter described the particular biological conditions of the aged and diabetics with lowered autonomic nervous function, and their relations with orthostatic hypotension. It further made clear what characteristic functions should be given to care-taking devices used for the aged with diabetes after conducting standing-up experiments on the aged with diabetes. The 7th chapter summarized the thesis by describing the ergonomic characteristics that are required in the design of care-taking devices, including the necessity of user-minded design, and the establishment of a design system that can deal with the user's particular condition.

本研究由七章组成。第一章阐明了一般护理设备应具备哪些人体工程学特征，并评估了坐站转换设备作为支持独立生活因素的重要性。第二章阐述了站立时循环生理的反应机制。特别是，它描述了自主神经活动和脑循环的测量方法，这两者都是站立时生理测量所必需的。第三章阐述了站立时循环生理反应的特点以及由这种反应引起的体位性低血压（脑性贫血）的发生机制，然后描述了在老年人身上进行的实验。第四章从循环生理学的角度阐述了高级中枢神经系统在站立时的循环调节中发挥重要作用的理论。第五章评估了坐站转换装置的功能，该装置通过按钮开关将座椅升高并向前倾斜以帮助用户站立。第六章阐述了老年人和糖尿病患者自主神经功能低下的特殊生物学状况及其与直立性低血压的关系。通过对糖尿病老人进行站立实验，进一步明确了糖尿病老人护理器具应具备哪些特色功能。第七章对全文进行了总结，描述了护理设备设计中所要求的人体工程学特征，包括以用户为中心的设计的必要性，以及建立能够处理用户特定情况的设计系统。
