SBIR Phase I: Smartphone-based Automated External Defibrillator

这个小企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力是通过连接到智能手机的小型化自动外部充电器的扩散来拯救生命。心脏骤停（SCA）今年将在医院外杀死超过32.5万美国人。如果不及时治疗，SCA会导致死亡。如果AED可用，它可以挽救一个人的生命;一些估计表明，如果AED可用并在需要时使用，可以挽救的人数增加27%。嵌入智能手机外壳的微型AED可以通过使AED更容易获得并确保携带它们的人能够获得紧急医疗服务来挽救生命。该策略是为执法人员、消防队员、EMS人员和潜在的公民第一响应者配备这种设备，并使用智能手机技术确保他们在遇到SCA的人附近时可以联系到。它提供了一个新的范例在第一反应的机会：AED载体可以在SCA的第一个关键时刻被定位。通过这项研究，每年可以挽救数十万人的生命。这个小企业创新研究（SBIR）第一阶段项目将证明与智能手机集成的符合法规的小型AED的概念。这项工作包括研究和设计组件和电子器件，以实现这一关键医疗设备的创建，并实现三个总体目标：（1）设计和开发封装的元器件、互连线，固件和软件实现手-通过评估高压电源和开关电子器件，并完成能够产生所需电压的电源转换器和开关设计，该系统包括：（1）从车载锂离子电池获得能量并支持双相波形;（2）开发实现设备本身所需的智能手机软件和固件，通过紧急协议引导用户，并将GPS信息发送到EMS，以允许他们定位近距离的第一响应者;（3）将硬件和软件集成到原型中，演示第2阶段中形状因子功能单元的路径。作为这项工作的一部分，互连和封装方法的研究和设计将为医疗领域内外的无数电子产品的小型化提供深入的见解。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR)Phase I project is to save lives through the proliferation of miniaturized automated externaldefibrillators that attach to smartphones. Sudden cardiac arrest (SCA) will kill more than 325,000Americans this year outside of the hospital. An SCA can cause death if it is not treated inminutes. If an AED is available, it can save a person's life; some estimates suggest a 27% increasein the number of people who could be saved if AEDs are available and used when needed. Aminiaturized AED embedded in a smartphone case could save lives by making AEDs moreavailable and ensuring those who carry them are reachable by emergency medical services. Thestrategy is to equip law enforcement, firefighters, EMS personnel, and potential citizen first responderswith this device and use smartphone technology to ensure they are reachable whenin proximity to someone experiencing an SCA. It provides an opportunity for a new paradigm infirst response: AED carriers that can be located during the first critical moments of an SCA.Through this research, hundreds of thousands of lives can be saved each year.This Small Business Innovation Research (SBIR) Phase I project will prove out the concept of aregulatory-compliant miniaturized AED that integrates with a smartphone. The work includesresearching and designing components and electronics that will enable creation of this criticalmedical device and accomplish three overarching goals: (1) design and develop the miniaturizedcomponents, interconnects, firmware and software necessary to implement the hand-held AEDSmartphone case in Phase Two by evaluating high voltage power supply and switchingelectronics and completing a power converter and switching design capable of generating therequired energy from an on-board lithium-ion battery and supporting a bi-phasic waveform; (2)develop the smartphone software and firmware necessary to implement the device itself, guidea user through the emergency protocol, and send GPS information to EMS to allow them tolocate proximal first responders; (3) integrate the hardware and software into a prototype thatdemonstrates a path to a form factor function unit in Phase 2. Research and designs ofinterconnects and encapsulation methods developed as part of this effort will offer insight intothe miniaturization of myriad electronics both within and outside the medical domains.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
