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

这个小型企业创新研究第一阶段项目建议开发一种使用射频识别(RFID)技术的定制射频集成电路(IC)。该射频芯片将用于心肺监护系统。该系统使用贴纸形式的一次性MEMS传感器，通过远程射频源远程接收电力。在该系统中，通过与个人计算机(PC)节点的无线通信来获得心音和肺音。通过PC，心音和肺音被图形化地呈现、记录或分析，以供进一步使用。PC节点将成为患者监护(PM)系统的一部分。该系统工作在新的医疗频段无线医疗遥测系统(WMTS)中，具有最小的外部干扰系统干扰。射频集成电路将由微控制器、非易失性存储器、指令定序器、检测电路和基本调制电路组成。整个计划中的IC都采用微功率设计。目前，市场上还没有一种可以用于短期和长期监控的无线、无电池系统。拟议的系统使用Stethgraph应用软件，将用完全数字化、无线和基于无电池标签的系统取代用于临床患者监测和远程患者监测应用的模拟电子听诊器。如果成功，该产品将带来成本的降低、系统的简单性、更高的可靠性、无线/无电池特性、更强的坚固性和舒适性。它将满足重要的临床需求，同时为数百万人，特别是那些预算有限的人，提供一个几乎是革命性的机会，使社会广泛进行肺脏和心脏监测。

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.
