Intended Use

The OmniPro™ System is intended for the measuring, recording and analysis of the electrical activity of a patient's brain through the attachment of multiple electrodes at various locations to aid in monitoring and diagnosis as routinely found in clinical setting for EEG/EMG/EOG/ECG/Air Flow/Oximetry.

Device Story

OmniPro™ is a dual-purpose amplifier system for polysomnography (PSG) and electroencephalography (EEG) in clinical settings. It captures physiological signals—EEG, EMG, EOG, ECG, nasal airflow, and oxygen saturation (SpO2)—via patient-attached electrodes and sensors. Signals travel to an amplifier module, then through a shielded multiconductor cable to an interface module and a PC-based data acquisition (DAQ) board. The system supports remote monitoring by transmitting data from a patient-side PC to a remote PC via modem over the public switched telephone network (PSTN). Clinicians use the remote PC to verify signal quality and electrode placement during collection and to analyze/store data post-recording. The system provides automated event logging and annotations to assist in clinical diagnosis. By enabling continuous monitoring and data recording, the device aids healthcare providers in assessing neurological and sleep-related conditions, facilitating timely clinical decision-making.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing, including safety testing per IEC 60601-1, electromagnetic compatibility and immunity testing per IEC 60601-1-2, and software compliance testing against design requirements.

Technological Characteristics

System consists of a 25-channel isolated differential amplifier module, interface module, and PC with DAQ board. Features include programmable montage selection (up to 1000), selectable digital filters, master notch filter, and electrode impedance check via LED indicators. Sampling rate up to 1080 Hz/channel. Connectivity via shielded multiconductor cable (up to 50 ft) and modem for remote monitoring. Power supplied via DAQ board. Software performs data acquisition, storage, and analysis.

Indications for Use

Indicated for patients requiring clinical monitoring and diagnosis of electrical brain activity, including EEG, EMG, EOG, ECG, airflow, and oximetry measurements.

Regulatory Classification

Identification

An electroencephalograph is a device used to measure and record the electrical activity of the patient's brain obtained by placing two or more electrodes on the head.

#### 6. Description:

The OmniAmp is a dual-purpose amplifier system for use in polysomnogram (PSG) and electroencephalogram (EEG) studies in a hospital or diagnostic center.

The system hardware consists of an amplifier module with electrode inputs, an interface module and a personal computer (PC) with a data acquisition (DAQ) board. Electrodes

{1}------------------------------------------------

and sensors on the patient are connected to the amplifier module, which in turn is connected via a multiconductor cable to an interface box. The interface box is connected via a second multiconductor cable to the DAQ board in the PC, which is used to process display and store the EEG or PSG data. DC power to the amplifier is supplied from the DAQ board through the multiconductor cable. The PC at the patient location is connected to a second PC at a remote monitoring center via modem over the public switched telephone network (PSTN). In EEG studies, the remote PC is used to monitor the waveform data as it is collected by the patient PC to ensure adequate electrode placement and signal quality. At the end of the recorded data is transferred from the patient PC to the remote PC. where it is analyzed and stored.

The amplifier module comes in PSG and EEG versions. These modules utilize the same internal amplifier hardware. They differ in terms of the configuration of the electrode inputs to the amplifier channels. Both versions of the amplifier modules have male safety electrode receptacles for connection of each electrode. They have a graphic panel to indicate the location and name for each electrode connection. The PSG amplifier module has an OEM oximetry module that works with a finger sensor to detect the oxygen saturation (SPO2) and pulse rate. Both versions utilize the same interface cable to connect the amplifier module to an interface module located next to the PC. The interface cable may be up to 50 feet long and is shielded to reduce EM1. Both versions may have a clip to secure the box to the bed covers and may have a means to connect a lanyard for hanging the module from the patient's neck to allow for patient mobility.

The amplifier module has twenty-five electrically isolated differential amplifier channels. Twenty-one of the amplifier channels has the same gain and bandwidth settings and is used for the EEG. EMG, and EOG signals. The amplifier has one channel set for ECG, two channels set for interface with the respiratory effort piezoelectric belt sensors and one channel set to interface with the nasal airflow thermal type sensors. In the PSG mode, the electrode box connects thirteen (twelve in home use configuration) EEG/EMG/EOG amplifier channels, one ECG channel and the three respiratory amplifier channels to patient electrodes. In the EEG mode, the electrode box connects twenty-one amplifiers, set for EEG signals, and one ECG amplifier to the appropriate patient electrodes. The output cable connects all twenty-five-amplifier channels to the DAQ board where the system selects the channels for use in the patient study.

The interface cable carries status information between the interface module and the amplifier module in addition to the measured signals and power In the EEG mode, a iumper in the electrode cap receptacle indicates when it is connected. A digital line from the DAQ card activates the calibration signal to the amplifier channels. These digital inputs and outputs are connected from the amplifier to the DAQ board in the PC via the interface cable. If necessary, the Digital Input/Output (DIO) lines from the DAQ board in the PC will be used to select between PSG and EEG modes and to select the gain of the amplifier channels. The cable from the amplifier module to the PC DAQ board can be up to 50 feet long. It is shielded and has wires grouped to separate sensitive signal wires from the oximeter serial data, any DIO lines and +5V power for the amplifier
