无线血压计设计及其数据加密方法

Design of Wireless Blood Pressure Monitor and Its Data Encryption Method

为方便对病人的血压进行测量,并对测量的数据进行安全可靠传输,该文设计了一种无线血压测量系统。通过掌上电脑(PDA)、射频设别技术(RFID)、蓝牙技术,实现了对病人信息及血压、心率数据的读取和统计分析等功能。使用IDEA和RSA联合算法对患者的数据和IDEA算法的密钥进行加密,以保证患者数据的安全性。经某病区试用表明,该系统测量数据精度高,传输安全可靠,并提高了护士的工作效率。

A wireless blood pressure measurement system was designed to facilitate the measurement of the patient＇s blood pressure and to transmit the measured data safely and reliably. Through PDA, radio frequency identification technology（RFID） and bluetooth technology, the function of reading patients＇ information and statistics and analysis of blood pressure, heart rate data was realized. The IDEA and RSA joint algorithms were used to encrypt the patients＇ data and the key of the IDEA algorithm to ensure the security of the patient＇ data. The test results showed that the system had high accuracy of measurement data, safe and reliable transmission, and improved the nurses＇ work efficiency.
