摘要
目的:研制一种跟踪观测仪器对CT、MRI增强扫描后的患者生命体征进行实时监测,对患者不适及过敏反应自动预警。方法:该仪器主要由分机、主机及大屏幕显示屏3个部分构成。采用超低功耗数字式血氧板LPDSPO2V1.4及指套传感器采集患者血氧饱和度及心率体征数据,采集到的数据经NRF24L01无线数据传输模块以无线方式发送到主机,主机接收到数据自动分析、保存数据,超限自动报警,并将数据发送到大屏幕电子显示屏上显示。结果:该仪器能较好地监测患者血氧饱和度及心率体征,对过敏反应及时提出预警。经临床应用1 a,观察到轻度过敏反应患者87例,严重过敏反应3例,未发生死亡病例。结论:该仪器安全有效,减少了CT和MRI增强扫描后严重过敏反应的发生,进一步保障了患者安全,值得临床推广应用。
Objective To develop a tracking monitor for patient vital signs after CT and MRI enhanced scanning so as to execute auto alarm in case of patient discomfort and allergic reactions.Methods The monitor composed of a sub machine,a principal machine and a large-screen display used ultra-low power digital blood oxygen plate LPDSPO2V1.4 and fingertip sensor to acquire data on blood oxygen saturation and heart rate,the acquired data were transmitted to the principal machine with NRF24L01 wireless transmission module,and then the principal machine executed data auto analysis,storage,auto alarm for out-of-limit data and sent the data to the display.Results The monitor could be used for checking blood oxygen saturation and heart rate as well as implement early warning against allergic reactions.One-year trials proved that there were no death in case 87 cases of minor allergic reactions and 3 severe ones occurred.Conclusion The monitor proves its safety and efficiency by decreasing the incidence rate of severe reactions after CT and MRI enhanced scanning,and thus is worthy promoting clinically
