AMBULATORY WIRELESS SLEEP MONITOR

该项目将开发和测试一种动态无线睡眠监测仪 (AWSM)系统。这是AWSM系统测量和传输生理的 用于睡眠监测和睡眠异常诊断的信号。这 将允许在不束缚受试者的情况下在家中监测睡眠 还可以在任何医院对病人进行监控 床。医院外设有专门的睡眠监测单位。 AWSM将能够记录长达12小时的生物电信号 例如EEG、EOG、ECG和EMO以及与呼吸相关信号 作为鼻腔气流(发热)和胸壁呼吸用力的测量 (Piezo)在家庭环境中对门诊患者的影响。建议数 系统利用了已经被开发的遥测技术 由克利夫兰医疗设备公司在之前的NIH第一阶段和 第二阶段SBIR赠款。所有的电极和呼吸道都是 连接到一个小型、轻便的柔性外壳，它通过 1 mW调频信号。这最大限度地减少了对患者正常生活的干扰 睡吧。这一无线功能与 现有笔记本电脑包括： *最大限度地减少睡眠期间电极的意外脱离 家居环境。 *提供可靠性更高的家庭睡眠监测器，这将减少 睡眠研究成本降低75%，并提供更自然的睡眠，消除了 “首夜效应”和置身其中的心理效应 医院。 *舒适的睡眠状况，这对 老年患者和儿童，允许患者轻松下床 在房子里四处走动。 *实用的婴儿监测系统。无线功能非常强大 在研究婴儿方面很重要，因为他们倾向于抓住和拉动 电线。 建议的商业应用：除了用于监控 睡眠时，AWSM系统可以用来传达生命体征 患者在医院或在家中不干扰类似的 其他病人的系统。同一单位有许多工业和 用于实时控制和监控的商业应用。AWSM 系统还可以用于各种市场，如进行特殊 在工作场所学习如何控制虚拟现实游戏 脑电波。

This project will develop and test an Ambulatory Wireless Sleep Monitoring (AWSM) System. This the AWSM system measures and transmits physiological signals for sleep monitoring and diagnostics of sleep abnormalities. This will allow at-home sleep monitoring without having the subject tethered with wires and also enables the patients to be monitored in any hospital bed. outside the specialized hospital sleep monitoring units. AWSM will be capable of recording up to 12 hours of bio-electric signals such as EEG, EOG, ECG, and EMO as well as respiratory related signals such as nasal airflow (thermistry) and chest-wall respiratory effort measurement (Piezo) on ambulatory patients in their home environment. The proposed system takes advantage of the telemetry technology that has already been developed at Cleveland Medical Devices Inc. under prior NIH Phase I and Phase II SBIR grants. All the electrodes and respiratory channels are connected to a small light-weight flexible case which transmits the data by 1 mW FM signals. This minimizes interference with the patient's normal sleep. This wireless feature has several advantages compared to the existing portable systems including: * Minimizing accidental detachment of the electrodes during sleep at the home environment. * Providing a higher reliability home sleep monitor which will reduce the cost for sleep studies by 75% and provide more natural sleep, eliminating "first-night effects" and the psychological effects of being in the hospital. * Comfortable sleeping condition, which is extremely important for the elderly patients and children, allowing patients to easily leave their beds and move around the house. * Practical system for infants monitoring. The wireless feature is very important in studying the infants because they tend to grab and pull the wires. PROPOSED COMMERCIAL APPLICATION: In addition to being used to monitor sleep, the AWSM system can be used to communicate the vital signs on patients iii the hospital or at home without interfering with similar systems of other patients. The same unit has numerous industrial and commercial applications for real time control and monitoring. The AWSM system can also be used for markets as diverse as conducting special studies in the workplace to controlling virtual reality games with brainwaves.
