Intended Use
This device is intended for use in a sleep laboratory for the acqusition, display, storage, and analysis of polysomnography data obtained from a polygraph with IRIG compatible outputs. It's purpose is to assist a qualified sleep practitioner in the diagnosis of sleep disorders in patients 13 years of age and older. To use the analysis capabilities, there must be at least two EEG channels, two rapid eye movement channels (electroocculograms), a chin EMG (electromyogram) channel, a leg EMG channel, an airflow channel, two respiratory effort channels, and an oxygen desaturation channel. This device is to be used only under the direction of a physician or qualified sleep technician.
Device Description
POLYSMITH is a polysomnography data acquisition, analysis, display, and storage system, which accepts polysomnography data and allows the operator to view the data on the computer monitor. The device also automatically analyzes the data to determine the sleep stage for each thirty-second epoch and to detect apneas and hypopneas. The hardware consists of a personal computer with an enclosed analog-todigital converter and a connector block for conveniently connecting the input data leads. The device is designed to input data from a polygraph that has IRIG-compatible outputs. To use all analysis capabilities, there should be at least two EEG channels, two rapid eye movement channels (electro-occulograms), a chin EMG (electromyogram), a leg EMG, an ECG, airflow, two respiratory effort channels and an oxygen saturation channel. The software, which is running under the NT operating system, will display all of the acquired data on the computer screen for reviewing and operator editing. The automated analysis feature, designed tor subjects 13 years of age and older, generates multiple reports, including a sleep stage summary, describing the sleep data.

Unknown
The description mentions "automatically analyzes the data to determine the sleep stage for each thirty-second epoch and to detect apneas and hypopneas," which could potentially involve AI/ML, but the document does not explicitly state the use of these technologies. The lack of mention of training or test sets for AI/ML models further contributes to the uncertainty.

No
The device is described as a system for the acquisition, display, storage, and analysis of polysomnography data, intended to assist in the diagnosis of sleep disorders. It does not provide treatment.

Yes
The intended use explicitly states, "It's purpose is to assist a qualified sleep practitioner in the diagnosis of sleep disorders."

No

The device description explicitly states that the hardware consists of a personal computer with an enclosed analog-to-digital converter and a connector block, indicating it includes hardware components beyond just software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: This device acquires, displays, stores, and analyzes polysomnography data. This data is obtained from a polygraph which measures physiological signals directly from the patient's body (EEG, eye movements, muscle activity, airflow, respiratory effort, oxygen saturation). It is not analyzing samples taken from the body.
  • Intended Use: The intended use is to assist in the diagnosis of sleep disorders by analyzing physiological signals, not by analyzing biological samples.

Therefore, this device falls under the category of a medical device used for physiological monitoring and analysis, not an In Vitro Diagnostic device.

Description of the test set, sample size, data source, and annotation protocol

The system performance was evaluated by analyzing six all-night sleep records recorded to optical disk at the Henry Ford Sleep Diagnostic Center (HFSDC) in Detroit, Michigan and comparing the results obtained with the predicate device. In addition, the device performance was compared to human scoring, using two all night sleep recordings, from the HFSDC, of patients with severe sleep apnea. Each recording contains two EEG channels (central and occipital), two eye channels, a chin EMG channel, a leg EMG channel, an airflow channel, and one respiratory effort channel.

Warning:

_网站

The POLYSMITH software derives a description of a night's sleep from raw polysomnography data presented to the system. It is possible for the summary data to be incorrect for reasons including bad or missing polysomnography data, power failure, inaccurate calibration, and clinical data, to which the system has not been exposed. The POLYSMITH maintains all of the raw data. All summary data should be verified by examining the raw data on the computer monitor. The data can be viewed with the same resolution as a 10mm/sec. polygraph recording by viewing the data in the 10-second screen display mode. Since some of the sleep-staging criteria are based on specified amplitude levels, the EEG and EOG signals must be calibrated for accurate sleep It is recommended that a signal with known staging. waveform characteristics, such as a calibration signal, be included at the beginning or end of the recording as verification that the calibration was done.

Assessment of Performance Data

The device performance was compared with that of a predicate device, the Oxford SAC system. The system performance was evaluated by analyzing six all-night sleep records recorded to optical disk at the Henry Ford Sleep Diagnostic Center (HFSDC) in Detroit, Michigan and comparing the results obtained with the predicate device.
