专为医疗技术产品设计的单芯片无线平台

由一家工程咨询公司研发的无线电控制通信体系十分适用于植入物及其它的医疗产品。该产品名为SubQore,由Cambridge Consultants(Cambridge, UK; www.cambridgeconsultants.com) 推出,专为片上系统集成设计。它以医疗可植入服务(MICS)频段操作,而后者正逐渐成为全球医疗频段标准。

无线电结构体系融合低能耗和无线通信的能力, 适用于植入式产品的整合。

根据产业分析家的报告,全球植入设备市场以两位数增长的势头将持续到2007年。无线通信的发展为这一领域揭开了全新纪元,Cambridge Consultants无线商务部主管Richard Traherne如此说道。

电子技术的进步正在带动一系列新的植入应用方法。他还指出,SubQore的设计迎合了3大趋势:超低能耗,更加智能化,以及小型化。再结合MICS频段带来的机遇,我们看到适用于大量医疗产品的单芯片无线平台拥有庞大的市场需求。

低能耗是SubQore设计中的一项关键因素。其在0.05%工作循环和400kb/s的双向通讯速率情形下,平均消耗电流小于1A (峰值1.7mA)。在标准起搏器中,该装置借助一节锂电池可工作10年以上,且机器还能在短脉冲群内进行大量的数据传输。植入皮下时,其通信范围达2m。

Cambridge Consultants公司所预期的应用包括植入式起搏器、去纤颤器、遥控监视器、整形外科设备、泵控制器、神经刺激器及可吞入诊断产品。公司还计划对集成式芯片核心进行调整以适应不同应用领域。
