Intended Use
The QP-160AK Trend program is a software-only device intended to be installed on the EEG-1200A series electroencephalograph to record, calculate, and display EEG data obtained from the EEG-1200A system. This device is intended to be used by qualified medical practitioners, trained in Electroencephalography, who will exercise professional judgment when using the information. The intended use for each of the software's outputs is as follows: - . The EEG and aEEG waveforms are intended to help the user monitor the state of the brain. - . The user-defined Fast Fourier Transform (FFT) parameters of this software (FFT power) are intended to help the user analyze the EEG waveform. - The burst suppression parameters of this software (interval and bursts per . minute) are intended to aid in the identification and characterization of areas of burstsuppression pattern in the EEG. This device does not provide any diagnostic conclusion about the patient's condition to the user.

More Information

Not Found

No
The document describes standard EEG processing and trending features (aEEG, FFT, burst suppression) without mentioning any AI or ML algorithms. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".

No
The device is described as software that records, calculates, and displays EEG data to help monitor and analyze the state of the brain. It does not provide any diagnostic conclusions or indicate any treatment function.

No

The text explicitly states: "This device does not provide any diagnostic conclusion about the patient's condition to the user." It is intended to help users monitor, analyze, and identify patterns in EEG data.

No

The device is described as a software program installed on an existing electroencephalograph (EEG) system (EEG-1200A Series). While the QP-160AK itself is software, its function is entirely dependent on and integrated with the hardware of the EEG system to acquire and process the data. Therefore, it is not a standalone software-only medical device.

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

Here's why:

  • IVDs analyze samples taken from the human body (like blood, urine, tissue). This device analyzes electrical signals from the brain (EEG data) obtained directly from the patient via electrodes.
  • The intended use is to monitor and analyze EEG data to help qualified medical practitioners assess the state of the brain. While this information is used in a clinical context, it's not about analyzing a biological sample in vitro (outside the body).
  • The device description focuses on processing and displaying EEG waveforms and trends. This aligns with the function of an electroencephalograph accessory, not an IVD.

Therefore, the QP-160AK Trend program is a software accessory for an electroencephalograph, not an IVD.
