Improved EEG Patient Interface

描述：该SBIR的长期目标是将噪声干扰降至最低 并改善患者在脑电图（EEG）过程中的移动性， 一个新的轻量级头戴式接口。脑电图记录通常用于 诊断和评估许多神经系统疾病，包括癫痫，睡眠 呼吸暂停和脑炎。现有的EEG仪器包括复杂的 硬件和软件，但它们仍然受到严重限制， 患者头皮上的电极和测量之间的接口 系统这限制了移动性并损害了信号完整性， 连接可靠性。BIOMEC建议设计一种小型化的 放大器/处理器安装在柔性板的形状轻，薄 患者佩戴的头带。头带将与任何带有USB接口的PC连接 消除了中间计算机卡和软件。在第一阶段，我们设计了一个 32-通道微型系统，构建了单通道样机，并进行了测试 在实验室和五名患者身上的概念，结果达到或超过 预期在第二阶段提案中，我们将优化电路布局， 设计头带包装，开发固件和软件驱动程序， 制造一个商业样机，并在12台机器上测试整个系统。 患者最终产品承诺将为一个新的类别设定标准， 小型化的EEG硬件将允许患者的全范围活动， 简化了设置，提高了可靠性和信号质量。 拟议商业应用：不可用

DESCRIPTION: The long-term goal of this SBIR is to minimize noise interference and improve patient mobility during Electroencephalogram (EEG) procedures with a new lightweight head-worn interface. EEG recordings are routinely used in diagnosing and evaluating many neurological disorders including epilepsy, sleep apnea, and encephalitis. Existing EEG instruments include sophisticated hardware and software, but they are still severely limited by inadequate interfaces between the electrodes on the patient's scalp and the measurement system. This restricts mobility and compromises signal integrity and connections reliability. BIOMEC proposes to design a miniaturized amplifier/processor mounted on flexible boards in the shape of a light and thin headband worn by the patient. The Headband will interface with any PC with USB eliminating intermediate computer cards and software. In Phase I, we designed a 32-channel miniature system, constructed a single channel prototype, and tested the concept on the bench and on five patients with results that met or exceeded expectations. In this Phase II proposal, we will optimize the circuit layout, design the headband packaging, develop fimware and software drivers, manufacture a commercial prototype, and test the complete system on 12 patients. The final product promises to set the standard for a new class of miniaturized EEG hardware that will permit full range of patient activity, simplifies setup, and improves reliability and signal quality.
