目的 设计有创血压监测换能器固定装置,评价其应用效果。方法 换能器固定器包括调节带、固定底座、气泡水平尺三部分组成。选取2021年4月—2022年4月重症监护室行有创血压监测的患者60例,采用回顾性对照研究。对照组使用床旁固定杆固定压力传感器,试验组使用换能器固定装置将压力传感器固定进行测压。比较两组患者在不同体位血压监测的准确性、换能器移位或滑脱率、皮肤损伤及护士满意度情况。结果 两组患者不同角度的固定方法对有创血压和无创血压的影响,差异无统计学意义（P>0.05）;试验组换能器脱落率为0、偏移（0.80±1.45）cm、医疗器械相关性压力损伤的发生率为0,显著低于对照组（P<0.05）;护士总体满意度优于对照组。结论 有创血压监测换能器固定装置在确保测压准确性的同时,应用安全、便捷,护士满意度高。
Objective To design a transducer fixation device for invasive blood pressure monitoring and evaluate its application effect. Methods The transducer fixator was composed of adjustment belt,fixed base and bubble level. A total of 60 patients who underwent invasive blood pressure monitoring in intensive care unit from April 2021 to April 2022 were selected,and a retrospective control study was conducted. The pressure sensor was fixed by the bedside fixed rod in the control group,and the pressure sensor was fixed by the transducer fixation device in the experimental group for pressure measurement. The accuracy of blood pressure monitoring,the rate of transducer displacement or slip-off,skin injury and nurses' satisfaction were compared between the two groups. Results There was no significant difference between the two groups in the effect of different angle fixation methods on blood pressure（P>0.05）. The rate of transducer shedding in the experimental group was 0%,displacement was（0.80±1.45）cm and incidence of medical device-related pressure injury was 0%,which were significantly lower than those in the control group（P<0.05）. The overall satisfaction of nurses was better than that of the control group. Conclusion The invasive blood pressure monitoring transducer fixation device ensures the accuracy of pressure measurement,and is safe and convenient to use,with high satisfaction of nurses.
