Improved EEG Patient Interface

描述：此SBIR的长期目标是将噪声干扰降至最低 并在脑电(EEG)过程中改善患者的机动性 一个新的轻巧的头戴式界面。脑电记录经常用于 诊断和评估许多神经疾病，包括癫痫、睡眠 呼吸暂停和脑炎。现有的脑电仪器包括尖端的 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和 连接可靠性。BIOMEC建议设计一种微型 放大器/处理器安装在轻薄形状的柔性电路板上 病人佩戴的发带。该头带可与任何带有USB接口的PC连接 消除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，搭建了单通道样机，并进行了测试 替补席上的概念和五名结果达到或超过的患者 期望值。在这个第二阶段的方案中，我们将优化电路布局， 设计发带包装，开发Fimware和软件驱动程序， 制造商业原型，并在12月12日测试完整的系统 病人。最终的产品承诺为一个新的类别设定标准 小型化的脑电硬件将允许患者进行全方位的活动， 简化了设置，提高了可靠性和信号质量。 建议的商业应用：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.
