SBIR Phase I: RFID tags for cardiopulmonary monitoring in clinical setting

这项小型企业创新研究第一阶段项目建议使用射频识别（RFID）技术开发定制射频（RF）集成电路（IC）。该射频集成电路将用于心肺监测系统。该系统使用粘贴标签形式的一次性MEMS传感器，通过远程射频源远程接收电源。在该系统中，通过与个人计算机（PC）节点的无线通信获得心肺音。使用PC机，心肺声音以图形形式呈现，记录或分析以供进一步使用。PC节点将成为患者监测（PM）系统的一部分。该系统工作在新型医疗频带无线医疗遥测系统（WMTS）中，对外界干扰系统的干扰最小。射频集成电路将由微控制器、非易失性存储器、指令排序器、检测电路和基本调制电路组成。微电源设计贯穿整个集成电路规划。目前，市场上还没有一种可用于短期和长期监测的无线、无电池系统。采用听诊仪应用软件的拟议系统将取代模拟电子听诊器，用于临床病人监测和远程病人监测应用，采用完全数字化、无线和无电池标签的系统。如果成功，该产品将带来成本降低、系统简单、可靠性更高、无线/无电池功能、更强的稳健性和舒适性。它将满足一项重要的临床需求，同时为广泛的社会肺和心脏监测提供几乎革命性的机会，使其惠及数百万人，特别是那些预算有限的人。

This Small Business Innovation Research Phase I project proposes to develop a customized radio frequency (RF) integrated circuit (IC) using radio frequency Identification (RFID) technology. This RF IC will be used in cardiopulmonary monitoring system. The system uses a disposable MEMS sensor in the form of adhesive tags that receive power remotely through a remote radio frequency source. In this proposed system, heart and lung sounds are obtained through wireless communication with a personal computer (PC) node. With the PC, heart and lung sounds are presented graphically, recorded or analyzed for further use. The PC node will be part of a patient monitoring (PM) system. The system operates in the new medical frequency band wireless medical telemetry system (WMTS) with a minimum interference from external interference system. The RF IC will consist of a microcontroller, nonvolatile memory, instruction sequencer, detection circuit, and basic modulation circuitry. Micro-power designs are used throughout the planned IC.At present a wireless, battery-less system that can be used for short term and long term monitoring is not available on the market. The proposed system, using Stethographics applications software, will replace analog electronic stethoscopes for clinic patient monitoring and remote patient monitoring applications with a fully digitized, wireless and battery-less tag-based system. If successful this product bring reduction in cost, simplicity of the system, higher reliability, wireless/ battery-less features, greater robustness and comfort. It will meet an important clinical need while providing an almost revolutionary opportunity for widespread societal lung and heart monitoring reaching millions of people including in particular those with limited budgets.
