nurse method to use hand Pressure Sensor 圧力測定センサ

项目摘要

The characteristics of nurse's method to use hand has been studied using pressure as a parameter. As a result, it was revealed that their method to use hand is different between the experienced nurses and beginners (student nurse), and laterality in their method to use hand varies depending on the area of supporting surface. Furthermore, in order to understand the change of pressure with time, a 'Glove Pressure Sensor' was made by method of trial, in which pressure-sensitive and conductive rubber (Inaba Rubber Co. Ltd : SF4L) was patched on the inner surface of the cloth glove, and its characteristics was investigated. In this experiment, 28 points were set in one hand so as to measure in multiple points. As a result, linear relationship between pressure and output voltage was confirmed in the area ranging 625 to 2500 g/cm^2 except for the 3rd distal phalanx, while output voltage was tended to be saturated in the range over 2500 g/cm^2. The reason may be that the pressure is absorbed b … More y the cloth because the glove is between the sensor and the palm. So, there remains the problem for a practical use that detection range for pressure is limited, and currently improvement of the glove is tackled.In tandem with improvement of the glove, pressure measurement was attempted using the method without the glove. This was the method to measure the pressure applied to nurse's hand (right-handed), on whose palm the sensor is directly attached with a medical tape, when the nurse is lifting the simulation model of the human lower extremity. As a result, although the pressure applied to the palm when lifting the lower extremity varies depending on the nurses, there was a tendency that the pressure is supported focusing on '3 points' consisting of the 1st proximal phalanx, the palm below the 3rd proximal phalanx of the left hand and the palm below the 1st proximal phalanx of the right hand. The site immediately below the 2nd proximal phalanx of the left hand is used in place of the 3rd proximal phalanx of the left hand, or they are used concurrently.Based on the above, it was considered that the nurses support by dispersing their force in 'the triangle' or ensure the stability using '4 points' by further adding to these 3 points other one site immediately below the 2nd proximal phalanx of the left hand when lifting the lower extremity.

以压力为参数，研究护士用手方法的特点。结果显示，有经验的护士和初学者（实习护士）使用手的方法不同，并且他们使用手的方法的偏侧性取决于支撑表面的面积。此外，为了了解压力随时间的变化，通过试验方法制作了“手套压力传感器”，其中压敏和导电橡胶（稻叶橡胶有限公司：SF 4L）贴在布手套的内表面上，并研究了其特性。在该实验中，在一只手上设置28个点，以便在多个点中测量。结果表明，在625 ~ 2500 g/cm^2范围内（第3远节指骨除外），压力与输出电压呈线性关系，而在2500 g/cm^2以上范围内，输出电压趋于饱和。原因可能是压力被吸收了B ...更多信息因为手套在传感器和手掌之间。因此，在实际应用中，存在压力的检测范围有限的问题，目前正在努力改进手套，与手套的改进相结合，尝试使用不戴手套的方法进行压力测量。这是当护士举起人体下肢的模拟模型时，测量施加到护士的手（右手）上的压力的方法，在护士的手掌上直接附着有医用胶带。结果，虽然在抬起下肢时施加到手掌的压力根据护士而变化，但是存在压力集中在由左手的第一近节指骨、第三近节指骨下方的手掌和右手的第一近节指骨下方的手掌组成的“3点”上的趋势。用左手第二近节指骨正下方的部位代替左手第三近节指骨，或同时使用。基于上述情况，认为护士通过在“三角形”中分散力量进行支撑，或通过在左侧第二近节指骨正下方的这3个点上进一步增加另一个点，使用“4点”来确保稳定性抬起下肢时，用手。少
