SBIR Phase I: Smartphone-based Automated External Defibrillator

小型企业创新研究(SBIR)第一阶段项目的更广泛影响/商业潜力是通过智能手机上安装的微型自动体外除颤器的普及来拯救生命。心脏骤停(SCA)今年将导致超过325,000名美国人在医院外死亡。如果不在几分钟内得到治疗，SCA可能会导致死亡。如果有AED，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，可以拯救的人数增加了27%。嵌入在智能手机壳中的微型AED可以通过使AEDs更容易获得并确保紧急医疗服务可以到达携带AEDs的人来拯救生命。该战略是为执法部门、消防员、EMS人员和潜在的公民急救人员配备这种设备，并使用智能手机技术确保当他们靠近正在经历SCA的人时可以联系到他们。它为第一反应提供了一个新的范式：可以在SCA的第一个关键时刻定位的AED携带者。通过这项研究，每年可以拯救数十万人的生命。这个小企业创新研究(SBIR)第一阶段项目将证明符合监管规定的微型AED的概念，该概念与智能手机集成。这项工作包括研究和设计部件和电子产品，以创造这种关键的医疗设备，并实现三个总体目标：(1)设计和开发在第二阶段实现手持AED智能手机外壳所需的小型化部件、互连、固件和软件，方法是评估高压电源和开关电子设备，并完成能够从机载锂离子电池产生所需能量并支持双相波形的电源转换器和开关设计；(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，并向EMS发送GPS信息，使其能够定位近端的第一响应者；(3)将硬件和软件集成到一个原型中，该原型展示了在第二阶段中实现外形因数功能单元的途径。作为这一努力的一部分，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微型化提供洞察力。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势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.
