隨著社會老齡化的日益加劇,對老年人健康的關(guān)心已經(jīng)成為重要的社會問題。另外,一些突發(fā)性疾病和家庭保健,如心血管疾病、孕婦、胎兒、嬰兒、幼兒的保健也需要*的家庭監(jiān)護。所以,研究基于公用網(wǎng)絡(luò)的家庭醫(yī)療監(jiān)護,建立小區(qū)醫(yī)療網(wǎng)絡(luò),從而組成一個醫(yī)院護理系統(tǒng)網(wǎng)絡(luò),不僅可以增加病人的安全性和改善人們的生活質(zhì)量,還能使醫(yī)院更有效地提高管理人員、醫(yī)生和護士的工作效率,協(xié)調(diào)相關(guān)部門有序工作。
在某些情況下,使用有線方式的監(jiān)護系統(tǒng)的實施成本將遠遠超過購買監(jiān)護設(shè)備所花費的費用。例如,在一個多社區(qū)醫(yī)療監(jiān)護網(wǎng)絡(luò)中,把實時監(jiān)護病人的生理參數(shù)傳輸?shù)竭h程監(jiān)控中心及所有數(shù)據(jù)的遠程備份,都是一筆龐大的開支,維護成本更是驚人。雖然引入無線監(jiān)護網(wǎng)絡(luò),可以解決一些問題,但基于藍牙、GPRS 等技術(shù)的社區(qū)醫(yī)療監(jiān)護系統(tǒng)存在相應(yīng)的不足之處,如無線輻射的安全性、無線終端的快速移動、無縫漫游和無線網(wǎng)絡(luò)成本等等。

ZigBee 技術(shù)的出現(xiàn)為傳感器信號的無線傳輸提供了新的解決方案。ZigBee節(jié)點有幾十米的覆蓋范圍,且可以增加路由節(jié)點,擴展覆蓋范圍,另外它還具無線輻射小、傳輸數(shù)據(jù)安全和成本低等優(yōu)點,因此適用于家庭住宅。同時由于生理監(jiān)護信號的數(shù)據(jù)傳輸流量不大,傳輸速率為250kbit/s的ZigBee能夠滿足生理數(shù)據(jù)傳輸要求。ZigBee傳感節(jié)點可自由靈活地加入和離開網(wǎng)絡(luò),具有低功耗和低成本的特點。此外,電力線具有高速(骨干網(wǎng)速度已經(jīng)達到了上百Gbit/s)、以電力輸電線路作為傳輸載體(目前我國擁有*長度*二的電力輸電線路)等優(yōu)點,并且電力線載波通信被國外傳媒喻為“未被挖掘的金山”。我們可以看到,如果把ZigBee和PLC技術(shù)有機的結(jié)合起來,它不僅彌補現(xiàn)有社區(qū)醫(yī)療監(jiān)護系統(tǒng)的一些弊端,緩解了居民對醫(yī)療監(jiān)護的需求,還很符合并不富裕的中國。
