To more efficiently enhance the patient transfer skills of nursing students, this study aims to integrate a transfer skills evaluation system and a robot patient. The evaluation parameters, namely, the translational acceleration of the waist, rotational speed of the chest, and joint angles of the shoulder, hip, and knee, were selected on the basis of the pre-experimental results obtained with a simulated patient acted by the human individuals. To measure these parameters, inertial measurement unit (IMU) and angular position sensors were installed on the robot patient. An experiment was conducted with four nursing teachers to verify whether the robot patient could distinguish the incorrect methods of the transfer skills, determined to be a common mistake made by the nurses. According to the results, most transfer steps had the same effect on the simulated patient and the robot patient, which demonstrates that the robot patient is a suitable substitute for an actual patient. However, in certain steps, the robot patient was not able to distinguish between the correct and incorrect methods using the chosen parameters owing to the differences being insignificant. These insignificant differences were mostly attributed to the passive joint design of the robot patient.

配备惯性测量单元和角度位置传感器以评估护士转移技能的机器人患者的开发和验证

为了更有效地提高护理学生的患者转移技能,本研究旨在整合转移技能评估系统和机器人患者。评估参数,即腰部的平移加速度,胸部的旋转速度以及肩部,髋部和膝盖的关节角度,是根据模拟患者在实验中获得的实验结果而选择的。人类个体。为了测量这些参数,在机器人患者身上安装了惯性测量单元(IMU)和角位置传感器。对四名护理老师进行了一项实验,以验证机器人患者是否可以区分错误的传递技巧方法,这被确定为护士的常见错误。根据结果​​,大多数转移步骤对模拟患者和机器人患者具有相同的效果,这表明机器人患者可以替代实际患者。但是,在某些步骤中,由于差异不明显,机器人患者无法使用所选参数区分正确和错误的方法。这些微不足道的差异主要归因于机器人患者的被动关节设计。
