SCBA OXIMETRY FOR FIRE FIGHTER PHYSIOLOGIC MONITORING

理想的电子火场管理系统应该包括传感器，这些传感器可以检测环境危险，监控在极端高温和劳累条件下工作的消防员的生理状态，并持续显示所有人员的身份和位置。人们寻求技术解决方案，因为消防服务中出现了令人无法接受的死亡、受伤和伤残率。拟议的项目重点是通过基于SCBA的血氧仪系统、无线电遥测和处理软件对佩戴个人防护装备的人员进行远程生理状态监测。在第一阶段，BioAsyst将根据经验优化血氧计传感器发射器和探测器元件之间的距离，以确保额部反射模式下的信号可靠性。BioAsyst将设计、建造和验证少量感应式SCBA面具，并针对这一应用改进处理算法。然后，硬件和软件将用于一系列实验，以识别预测参数，并用于实时火场监测。第二阶段将根据个人生理反应校准警报级别，从而形成可靠的、用户定制的远程监控系统。第三阶段将监督最初的生产和营销。BioAsyst将继续扩展该设备的功能，在成熟后加入额外的传感功能。拟议的商业应用：该设备的商业市场包括国内外消防人员、危险物质应急人员、战斗和危险任务、军事、采矿、有限空间作业和基础研究应用。

An ideal electronic fireground management system will incorporate sensors that can detect environmental hazards, monitor the physiologic status of fire fighters working under conditions of extreme heat and exertion, and continuously display the identities and location of all personnel. Technology solutions are sought because of the unacceptable death, injury and disability rates seen in the fire service. The proposed project focuses on remote physiologic status monitoring of personnel wearing PPE through SCBA-based oximetry systems, radio-telemetry and processing software. During Phase I, BioAsyst will empirically optimize the distance between the oximeter's sensor emitters and detector elements to ensure signal reliability in reflectance mode at the forehead. BioAsyst will design, construct, and validate a small number of sensorized SCBA masks and refine processing algorithms for this application. The hardware and software will then be used in a series of experiments to identify predictive parameters with utility for real time fire ground monitoring. Phase II will calibrate alarm levels to individual physiologic responses, resulting in a reliable, user-customized remote monitoring system. Phase III will oversee initial production and marketing. BioAsyst will continue to expand the capabilities of the device, incorporating additional sensing capabilities as they mature. PROPOSED COMMERCIAL APPLICATION: The commercial markets for this device include foreign and domestic fire service personnel, hazmat responders, the combat and hazardous duty military, mining, confined space operations, and basic research applications.
