本文介绍了我们对手指康复装置的开发研究，特别是我们新设计的用于手指康复的气动执行器原型。由于尼龙薄膜作动器可以在低气压下作动，因此，小体积的泵甚至可以作动尼龙薄膜作动器。包括尼龙膜致动器和由直流电机驱动的气泵的手指康复装置将适合于希望随时随地携带它的人在家中进行康复，因为致动器和气泵小而轻。尼龙薄膜驱动器设计用于两种手指运动。一个是对于手部瘫痪的人来说最重要的延伸。另一种是用于屈曲，每个关节角度和关节之间的致动器的长度可以针对个人进行调整。该致动器在低气压下被致动，并且即使由低功率DC马达驱动的小体积空气泵被用于驱动单元也辅助手指运动。在我们制作尼龙膜致动器的原型之前，我们考虑使用现有的由弹性体制成的软气动致动器之一用于康复装置。但是，在低气压驱动装置下，它没有被激活。与以往的弹性体驱动器的重量约为30克相比，我们开发的尼龙膜驱动器的重量约为10克。因此，由致动器组成的设备将为人们的身体提供更少的压力，并允许他们在更长的时间内继续手指康复。由尼龙薄膜驱动器和小型驱动单元组成的康复装置也将是便携式和可穿戴的。此外，由于尼龙膜便宜且致动器易于制造，因此它比弹性体致动器更容易获得。
This paper presents our study on a development of a finger rehabilitation device, especially a prototype of pneumatic actuator we newly designed for a finger rehabilitation. Because the actuator made from nylon film can be actuated under low air pressure, a a-little-volume pump can even actuate the nylon-film actuator. The finger rehabilitation device including the nylon-film actuator and the air pump driven by a DC motor will be suitable for the rehabilitation at home for people who want to carry it anywhere and anytime because the actuator and the air pump are small and light. The nylon-film actuator is designed for two kinds of finger motions. One is for the extension that is most important to people with hand paralysis. Another is for the flexion, which each joint angle and the actuator's lengths between joints can be adjusted for individuals. The actuator is activated under low air pressure and assists finger motions even if a little volume air pump driven by a low power DC motor is used for a drive unit. Before we made a prototype of the nylon-film actuator, we considered using one of the existing soft pneumatic actuators made from elastomer for the rehabilitation device. However, it was not activated at under low air pressure drive unit. In contrast to the weight of the previous elastomer actuator that is approximately 30g, the nylon-film one we developed is approximately 10g. So, the device consisted of the actuators will give less stress for people's bodies and allow them to continue finger rehabilitation for extended periods of time. The rehabilitation device consisted of the nylon-film actuator with small drive unit will be also portable and wearable. Moreover, because the nylon film is cheap and the actuator can be easily made, it is more accessible than the elastomer actuator.
