Intended Use
The Trex HD is an Electroencephalograph intended to be used to acquire, display, store and archive electroencephalographic signals, intended for electroencephalographic (EEG) or level 1-2 polysomnographic (PSG) recordings. The Trex HD amplifier is designed to be used with Natus NeuroWorks™or Natus SleepWorks™ software.
Device Description
The Trex HD headbox is similar to the cleared Trex headbox (K042150). It contains a complete data acquisition system that has built-in amplifiers, A/D Converters, Digital Signal Processors, and storage devices. Trex HD, as the predicate device, is composed of 24 Referential Inputs, 2 DC Inputs, 3 Differential Inputs, Oximeter / Photic Connection, Patient Event Switch Connection, USB Connection, and Video Interface box. The wireless adapter is a part of Trex HD system. It connects to Camera (Camcorder) via LANC port. It is used to synchronize video frames with the EEG study recorded in Trex HD. It communicates wirelessly with the headbox and can store video synchronization internally in non-volatile memory in case the wireless communication is not possible. The Trex HD headbox is designed to work with an XLTEK computer system running NeuroWorks (K090019) or SleepWorks software (K090277). A camcorder can be used to record video. A (Trex HD) Video Interface Box is needed in order to synchronize video recording (on the camcorder) and EEG recording (on the Trex HD headbox).
More Information

No
The summary describes a data acquisition system for EEG/PSG recordings and associated software for display, storage, and archiving. There is no mention of AI or ML algorithms being used for analysis, interpretation, or any other function.

No.
The "Intended Use" states that the device is "intended to be used to acquire, display, store and archive electroencephalographic signals", which describes a diagnostic rather than a therapeutic function.

Yes

The intended use explicitly states that it is an electroencephalograph for acquiring, displaying, storing, and archiving electroencephalographic signals for EEG or polysomnographic (PSG) recordings, which are diagnostic procedures.

No

The device description explicitly details hardware components such as amplifiers, A/D Converters, Digital Signal Processors, storage devices, inputs, connections, a wireless adapter, and a headbox. While it works with software, it is not solely software.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is used to acquire, display, store, and archive electroencephalographic signals for EEG and PSG recordings. This involves measuring electrical activity from the body (specifically the scalp/face and body), not analyzing samples taken from the body (like blood, urine, or tissue).
  • Device Description: The description details a system for acquiring physiological signals (EEG and PSG) and synchronizing them with video. It does not mention any components or processes related to analyzing biological samples.
  • Lack of IVD Characteristics: The description does not mention any reagents, assays, or procedures typically associated with in vitro diagnostics.

In summary, the Trex HD is a device for measuring and recording physiological signals directly from the patient, which falls under the category of in vivo diagnostics or physiological monitoring, not in vitro diagnostics.

Hardware Set Up

The Trex HD headbox is designed to work with an XLTEK computer system running NeuroWorks (K090019) or SleepWorks software (K090277).

A camcorder can be used to record video. A (Trex HD) Video Interface Box is needed in order to synchronize video recording (on the camcorder) and EEG recording (on the Trex HD headbox).

Image /page/3/Figure/4 description: The image shows a diagram of a medical device setup. The diagram includes an XLTEK DT Computer connected via a USB to mini-USB cable to a camcorder and a USB 2.0 cable to a Trex HD Headbox. The camcorder is also connected to the Trex HD Video Interface Box via a LANC cable, and the Trex HD Headbox is connected to Patient Leads, with optional connections to a Patient Event Switch, Oximeter, and Photic Simulator.

Device-patient interaction. Accessories List:

The table below lists all accessories to the subject device. Accessories (1) to (8) enter in contact with the patient. Accessories (1) to (8) are to be connected at different regions of the scalpfface and body as illustrated on the image below. These sensors guarantees acquisition of the physiological signals and passively transfer them to the headbox. Characteristics of the sensors vary and are described (cleared) under their respective 510K submissions (see table).

Image /page/4/Figure/3 description: This image shows a diagram of a polysomnography (PSG) setup, which is a sleep study. The diagram includes various sensors attached to a person, such as EEG disc electrodes, body position sensors, respiratory effort sensor, and pulse oximeter sensor. The sensors are connected to a Trex HD Headbox, which is connected to a computer and other devices such as a camcorder and photic stimulator. A table provides descriptions and 510K numbers for the different components of the PSG setup.
