摘要： A seizure detection system including one or more circuits, the one or more circuits configured to receive an electroencephalogram (EEG) signal generated based on electrical brain activity of a patient and determine different types of metrics based on the EEG signal, the different types of metrics indicating non-linear features of the EEG signal. The one or more circuits are configured to determine whether one or more of the different types of metrics exhibit changes over time that meet a predefined level of statistical significance, generate a user interface, the user interface including a real-time trend of the EEG signal and the one or more of the different types of metrics, and cause a user interface device to display the user interface.

摘要： Systems, devices and methods for advanced electrode management in neurological monitoring applications include receiving sockets configured to receive connectors having groups of electrodes. The physician is not required to manually map each electrode with its corresponding input channel. Electrodes are coupled to the corresponding input channels in groups through connectors having a unique identification (ID). The system is configured to read the unique ID of each connector and establish its identity. Based on the ID, the system configures itself to automatically correlate or associate each electrode with its corresponding input channel when the connectors are first inserted into the receiving sockets, and again if the connectors are removed and re-inserted into different positions in the receiving sockets, to insure the electrodes are always mapped to the same input channels.

摘要： Apparatus, including an enclosure having a base and a cover with respective conductive layers. The conductive layers connect to form a shield attenuating electromagnetic radiation originating outside the enclosure in a range of 10 kHz-100 kHz by at least 20 dB within the enclosure. An adapter circuit within the enclosure processes electrophysiological signals to generate an output signal. A first connector passing through the enclosure connects to a probe to receive the electrophysiological signals and convey them to the adapter circuit. A second connector passing through the enclosure receives the output signal from the adapter circuit and conveys it to a console. A control input receives a control signal indicative of a frequency within the range, and a sensing circuit senses a magnetic field within the enclosure and outputs a warning signal when the magnetic field at the frequency indicated by the control signal exceeds a preset threshold.

摘要： The present disclosure facilitates capture of biosignal such as biopotential signals in microvolts, or sub-microvolts, resolutions that are at, or significantly below, the noise-floor of conventional electrocardiographic and biosignal acquisition instruments. In some embodiments, the exemplified system disclosed herein facilitates the acquisition and recording of wide-band phase gradient signals (e.g., wide-band cardiac phase gradient signals, wide-band cerebral phase gradient signals) that are simultaneously sampled, in some embodiments, having a temporal skew less than about 1 μs, and in other embodiments, having a temporal skew not more than about 10 femtoseconds. Notably, the exemplified system minimizes non-linear distortions (e.g., those that can be introduced via certain filters) in the acquired wide-band phase gradient signal so as to not affect the information therein.

摘要： A blood pressure monitoring device configured to attach and supply air to a blood pressure cuff can include a housing having an interior, a port configured to enable fluid communication between the interior of the housing and an interior of the blood pressure cuff, and an air intake configured to allow ambient air to enter the interior of the housing and further configured to inhibit liquids from entering the interior of the housing. The air intake can define a non-linear passageway for ambient air to enter the interior of the housing. The housing can have a first side and a first inner wall. The air intake can be defined by a first opening in the first side and a second opening in the first inner wall. The first opening can be not aligned with the second opening.

摘要： Fast recovery electrocardiogram (ECG) signal method and apparatus are provided. In one embodiment, an ECG apparatus includes an input for receiving a biometric cardiogram signal, such as a Wilson Central Terminal (WCT) signal, and a combiner, such as an adder, for producing a compensated signal. Processing circuitry produces an ECG reflective of the compensated signal and also outputs a signal corresponding to high frequency response of the compensated signal to compensate for low response of the biometric cardiogram signal to high frequency spikes. A resultant ECG is produced by the processing circuitry having pacing signal contribution within the biometric cardiogram signal cancelled.

摘要： The present disclosure lies in the general field of clinical electrocardiography (ECG), more specifically in ECG methods comprising precordial ECG amplitude measurements. The present invention relates to methods of determining a subject's corrected precordial ECG amplitude from an ECG measurement, which corrections are based on intraindividual changes such as the rotation position of the heart on the horizontal plane, and/or changes in body mass index. The methods are thus useful for adjustment of intraindividual changes over time in precordial ECG amplitudes, such as between two ECG measurements. The present invention further relates to a device, an apparatus and a computer program product, and to uses of said device, apparatus and computer program product in a method of determining a subject's corrected precordial ECG amplitude from an ECG measurement, and for improving the accuracy of electrocardiographic methods depending on precordial ECG amplitude measurements. For example, the methods and the device, apparatus or product can be advantageously used in a method of diagnosing left ventricular hypertrophy and/or hypertension in a subject.
