摘要
目的研制一种用于对正在接受肿瘤放射治疗的患者实施实时监护的系统。方法选用蓝牙无线脉搏血氧饱和度仪、笔记本电脑、键盘视频鼠标延长器等设备和器材,通过系统集成的方法实现对正在接受放射治疗患者的脉搏血氧饱和度和脉率的实时监测。结果测试结果显示,本监护系统脉搏血氧饱和度在98%、90%、85%和80%、75%、70%的检测误差分别为±1.2%和±2.9%;脉率在8个测试点的检测误差范围是±2 bpm;血氧和脉率变化的平均响应时间为7~8 s;在医用直线加速器出射线和不出射线两种状态下的测量结果无明显差异。结论本设计能够实时监测肿瘤患者在放射治疗中的脉搏血氧饱和度和脉率,在保障患者安全、减少医疗纠纷方面具有较好的临床应用价值,且配置成本低、操作简单,易于推广使用。
Objective To develop a system of real-time monitoring for patients during radiotherapy. Methods Bluetooth wireless pulse oximeter, laptop, keyboard and video mouse extender and other devices were selected frstly. Then, real-time monitoring of pulse oxygen saturation and pulse rate of patients during radiotherapy was achieved through systematic integration. Results The monitoring system test results showed that the measurement error of pulse oxygen saturation in the scale of 98%, 90%, 85% and 80%, 75%, 70% was ±1.2% and ±2.9%, respectively. Pulse rate detection error range was ±2 bpm. The average response time of SpO2 and pulse rate changes was between 7-8 s. There was no signifcant difference between the results of the two states of the accelerator beam on and the beam off. Conclusion This design can in real-time monitor the pulse oxygen saturation and pulse rate of tumor patients during radiotherapy, and has good clinical application value in protecting patients’ safety and reducing medical disputes. In addition, it is low cost of confguration and simple operation, and is easy to popularize and use.
