Ambulatory Real Time High Channel Count Electroencephalograph

描述(由申请人提供)：一种名为超宽带(UWB)的新无线网络标准使动态脑电图仪(EEG)仪器的创建成为可能，该仪器可以实时传输160个全带宽(DC到7.5 kHz)通道或256个临床带宽通道。它将采用模块化放大器设计，允许低噪声临床带宽或增强的宽带。它将在与系留系统进行的人体测试中进行比较评估。开发的UWB无线系统将适用于高通道数头皮脑电、皮质栅极、多接触深度电极和用于多个单单元记录的细丝微电极等应用。拟议的UWB无线脑电系统将首次能够记录自由行为和抓取人类的单个神经元细胞外动作电位(AP)和局部场电位(LFP)。它还将消除对患者移动的限制，以及对拴系系统造成的运动中人工制品的敏感性。超宽带(UWB)是一种快速崛起的无线电技术，具有在无线通信领域取得重大进展的潜力。UWB标准正式指定为IEEE 802.15.3a。大带宽的利用使UWB能够传输大量数据。癫痫是最常见的神经系统疾病之一。癫痫指的是无缘无故发作的倾向，包括许多不同的综合征。它的患病率为0.5%到1%。这相当于美国大约有200万人。此外，3%到5%的人口会在一生中的某个时候出现非发热性癫痫发作。多年来，脑电的无线电遥测一直被认为是癫痫监测界的一个目标。超宽带在脑电监测中的应用具有创新性。与速度较慢的现有技术相比，它将为该领域提供重大改进。目前还没有类似的设备可用。

DESCRIPTION (provided by applicant): A new wireless network standard called Ultra-Wideband (UWB) makes possible the creation of an ambulatory electroencephalograph (EEG) instrument that can transmit 160 full-bandwidth (DC to 7.5 kHz) channels or 256 clinical bandwidth channels in real time. It will be designed with modular amplifiers that allow either a low noise clinical bandwidth or an enhanced wide bandwidth. It will be comparatively evaluated in human tests against a tethered system. The developed UWB wireless system will be suitable for applications such as high channel count scalp EEG, cortical grid electrodes, multi-contact depth electrodes, and fine wire microelectrodes for multi-single-unit recording. The proposed UWB wireless EEG system will make possible for the first time recording single neuron extra-cellular action potential (AP) and local field potential (LFP) from freely behaving and seizing humans. It will also remove restrictions imposed on patient movement and susceptibilities to artifact from movement caused by a tethered system. Ultra-wideband (UWB) is a fast emerging radio technology with the potential for major advances in wireless communications. The UWB standard is officially designated IEEE 802.15.3a. The utilization of large bandwidth allows UWB to transmit large amounts of data. One of the most common neurological diseases is epilepsy. Epilepsy refers to the tendency to have unprovoked seizures, and encompasses a number of different syndromes. It has a prevalence of 0.5 to one percent. This translates to approximately two million persons in the United States. Furthermore, three to five percent of the population will have non-febrile seizures at some point in their life. Radio- telemetry of EEG has been recognized as a goal in the epilepsy monitoring community for many years. The application of UWB to EEG monitoring is new and innovative. It will offer a significant improvement to the field over the slower existing technology. No comparable device is currently available.
