LIGHTWEIGHT, PORTABLE EEG EVOKED POTENTIAL SYSTEM

描述(改编自申请人的摘要)：调查员建议 为了开发一种轻便、真正便携的多道电生理 一种可进行全方位常规临床脑电及诱发的系统 可能的手术范围很广，包括住院病人， 门诊患者，以及电池供电或完全供电的环境 电气隔离是必要的。该系统将有24个高增益脑电 通道，4个中等增益EOG或EMG通道，4个单端 仪器输入，2个GSR通道，2个专用听觉脑干反应 通道、1个专用EKG通道和2个阻抗气体描记通道。 CPU将是一台具有高分辨率VGA屏幕的笔记本计算机， 拥有450兆字节的数据存储和集成的高速数字 信号处理器。该系统将为用户提供可调整的过滤， 自动阻抗检查和自动放大器校准。它是 预计体重在20磅以下，与身体状况大致相同 连接盒的尺寸，并能够使用电池电源运行 7到8个小时。预计零售价约为18,000.00美元。

DESCRIPTION (Adapted from applicant's abstract): The investigator proposes to develop a lightweight, truly portable multi-channel electrophysiological system capable of doing full-scale routine clinical EEG and evoked potential procedures in a wide range of setting, including inpatient, outpatient, and environments where either battery power or complete electrical isolation is necessary. The system is to have 24 high-gain EEG channels, 4 intermediate-gain EOG or EMG channels, 4 single-ended instrument inputs, 2 GSR channels, 2 dedicated auditory brain stem response channels, 1 dedicated EKG channel, and 2 impedance pneumograph channels. The CPU is to be a notebook computer with a high resolution VGA screen, with 450 mega-bytes of data storage and an integrated high speed digital signal processor. The system is to provide user adjustable filtering, automatic impedance checking, and automatic amplifier calibration. It is expected to weigh less than 20 pounds with the approximate physical dimensions of an attach case and be capable of operating on battery power for 7 to 8 hours. A retail price of approximately $18,000.00 is projected.
