基于智能病房的监控系统设计

Monitoring System Design Based on Intelligent Wards

为了实现医疗监护智能化的发展,提高不同状态监护的可靠性,采用Zigbee技术研制了可满足一般病房监护需求的医用设备。系统以SON1303心率传感器准确检测心率,以MPX5050GP压力传感器为核心部件来检测血压,用抗干扰性强的热敏电阻检测呼吸,用结构简单易于实现的红外传感器检测点滴速度。结合强大的ZigBee无线传感网络,采集了人体的4个健康体征信息:心率、血压、呼吸、脉搏等生理数据,并且完成病人的自动控制输液和报警功能。

In order to implement the intelligent development of medical monitoring and improve the monitoring reliability under different conditions , this article developed a medical device that meets normal demands of ward monitoring based on Zigbee technology . In this system, an SON1303 heart-rate sensor is used to precisely detect heart rates, an MPX5050GP pressure sensor is regarded as a core component in order to detect blood pressure, a few high-interference thermistors are used to detect breath, and an infrared sensor, with simple structure that can be easily implemented, is used to detect dropping speed. Combining ZigBee wireless sensor network （WSN）, the device collects four kinds of health condition information of human body： heart rate, blood pressure, breathing and pulse rate, etc. Furthermore, the device comprehends attached functions, such as transfusion automatic control and alarming for patients .
