项目摘要

1. To investigate the influence of cold exposure to the patient with spinal cord injury, we measured the change of blood pressure, tissue blood flow and body temperature when the patient were moved in the cold room. When normal persons were exposed to cold, tissue blood flow decreased rapidly and BP increased gradually, but the spinal cord injured person's tissue blood flow and BP showed no change. So the patient has no sympathetic flow response that the core temperature of body is expected to decrease easily on the time of cold exposure.2. Not only the handicapped person but also the old-aged person who live in Hokkaido, the most northern island in Japan, are hoping for the realization on their more ourdoor activities, during the winter season when it has much snow and low temperature. Actually, most of them must be out of doors even if during the coldest season in the winter, to go shopping and hospitals, et al. The main device to transfer outdoors is wheelchairs. There are, however, many problems pointed out on wheelchairs to use during the winter ; very slippery on the road with snow and ice, casters were easy to bury in snow, and the rim of wheelchairs is too cold to handle. Therefore, it is strong necessary that the appropriate wheelchair for riding outdoors in the winter season is developed. In this work, an electric wheelchair with front-driving is developing to be satisfied with thus requirements. The design concept of it and the road ability test on iced or snowed road are reported.

1.为探讨冷暴露对脊髓损伤患者的影响，通过对脊髓损伤患者在冷室中移动时血压、组织血流量和体温的变化进行检测。正常人受冷后，组织血流量迅速下降，血压逐渐升高，而脊髓损伤者组织血流量和血压无明显变化。因此，患者无交感血流反应，在冷疗时，预期核心体温容易降低.在日本最北方的岛屿北海道，不仅是残疾人，老年人也希望在冬季多雪和低温的时候实现更多的户外活动。事实上，即使在冬天最冷的季节，他们中的大多数人也必须出门，去购物和医院等。然而，在冬季使用的轮椅上指出了许多问题;冰雪路面非常滑，脚轮容易埋在雪中，轮椅的边缘太冷而无法处理。因此，开发适合冬季户外骑行的轮椅是非常必要的。本研究所开发的电动轮椅车，正是为了满足这一需求。本文介绍了其设计思想和冰雪路面的路用性能试验。
