目的探讨有效的吸痰生物力学技术。方法采用一种新型的结合运动捕捉系统的气管吸痰模拟器，计算吸痰量和吸痰动作的生物力学参数。进行了一项实验室研究，包括12名具有3年以上吸痰经验的护士和12名没有任何临床吸痰经验的护理学生。计算吸痰量、最大导管插入长度和手部运动的生物力学参数。结果有经验组平均每秒吸痰量明显大于无经验组。两组患者的吸痰量均与腕部和前臂垂直运动路径的长度以及拇指旋转角速度呈正相关。结论腕关节垂直运动和拇指旋转可提高吸痰效果，避免不安全的深吸痰。
Purpose The aim of this study was to determine the effective biomechanical technique for suctioning phlegm. Methods A novel tracheal suctioning simulator combined with a motion capture system was used to calculate the amount of simulated phlegm suctioned and the biomechanical parameters of the associated suctioning manoeuvre. A laboratory study, including 12 nurses with > 3 years of suctioning experience and 12 nursing students without any clinical suctioning experience, was conducted. The amount of phlegm suctioned, the maximum length of catheter insertion, and the biomechanical parameters of hand movement were calculated. Results The mean amount of phlegm suctioned per second was significantly larger in the experienced group than in the non-experienced group. The amount of phlegm suctioned correlated positively with the length of the vertical path of motion of the wrist and forearm, and with the angular velocity of thumb rotation in both the groups. Conclusion Greater vertical motion of the wrist and thumb rotation improved the effectiveness of phlegm suctioning and prevented the need for deep suctioning, which is unsafe.
