目的 探讨自制防滑脱计数握力器在ICU机械通气患者握力锻炼中的应用效果。 方法 防滑脱计数握力器由握力球、手套、闪关灯、计数器、凸球、导电胶杆、凸粒等组成。 选取2022年6月-8月杭州市某三级甲等医院重症医学科50例机械通气患者作为应用对象，采用随机数字表法随机分成试验组和对照组，各25例，试验组使用防滑脱计数握力器，对照组使用传统握力球。 比较两组患者机械通气期间握力锻炼依从性、握力和双上肢肌力、握力球平均滑脱次数及患者满意度的差异。 结果 试验组患者握力锻炼依从率为96%，优于对照组 48%，差异有统计学意义（Z=-4.65，P＜0.05）；试验组握力、双上肢肌力、患者满意度均显著高于对照组（P＜0.05），对照组握力球机械通气握力锻炼期间平均滑脱2.48次，试验组无滑脱。 结论 防滑脱计数握力器能够提高ICU机械通气患者握力锻炼依从性，从而增加患者握力、肌力，患者满意度高。

Objective To investigate the application effect of self-made anti-skid counting grip dynamometer in grip strength exercise in ICU mechanically ventilated patients. Methods Anti-skid counting grip dynamometer consists of grip ball，gloves，flashing light，counter，convex ball，conductive rubber rod，convex particle and so on. 50 patients with mechanical ventilation from the Department of Critical Care Medicine of a tertiary hospital in Hangzhou from June to August 2022 were selected as application objects，and divided into control group and experimental group by the random number table method. 25 patients were in each group. The experimental group used the anti-skid counting grip dynamometer，and the control group used the traditional grip ball. The grip exercise compliance，grip strength，muscle strength of upper limbs，slippage times of grip balls and patient satisfaction were compared between two groups. Results The compliance of the experimental group was 96% which was higher than that in the control group （48%），and the difference was statistically significant （Z=-4.65，P< 0.05）. The increase of grip strength，muscle strength，and patient satisfaction in the experimental group were significantly higher than those in the control group （P<0.05）. The average slip times of the grip ball in the control group was 2.48 times，and there was no slip in the experimental group. Conclusion The application of anti-skid counting grip dynamometer in ICU mechanically ventilated patients can improve their compliance with grip strength exercise，thereby increasing their grip strength and muscle strength，and their satisfaction.
