Overview and Technical Description

General Description

Intended Use

The Trackit Solo is intended to be used in combination with a compatible Lifelines EEG amplifier for the collection and display of video and EEG data in EEG studies.

Intended User

The intended user of the device is a healthcare professional who has the training and knowledge to undertake EEG examinations and is familiar with EEG equipment and practice.

Trackit Solo Setup and Description

The Trackit Solo is a portable data acquisition and communications system that works in tandem with Lifelines EEG amplifiers (e.g. Trackit T4A) to allow EEG and video data to be recorded locally and monitored remotely. The Trackit Solo wirelessly receives data from the EEG amplifier (via Bluetooth) and relays that data, along with video data acquired from the onboard camera, via the EEG software package which runs locally on the Trackit Solo. The data can then be relayed to an approved cloud-based software (e.g. Stratus iEEG), which allows clinical staff to access and monitor the data from any compatible device. Alternatively, the data, which is recorded locally as well, can be accessed via a remote desktop application (e.g. TeamViewer).

The Trackit Solo comprises a 10” tablet PC with a high-definition, infra-red camera. The system is powered with a medical grade power supply to ensure patient safety. The HD camera is fitted to a retractable extension pole. The Trackit Solo feature a Lithium-ion battery power source and can run on battery for up to 3 hours (EEG software dependent)

The EEG System contains several wireless connections, including Bluetooth from the Trackit Solo to the amplifier, as well as WiFi and LTE from the Trackit Solo to a remote network for data upload to the cloud-based software.

The Trackit Solo contains an infrared camera (e.g. Lifelines Neuro Trackit Cam) that can be manually repositioned to keep the patient in view. This camera is mounted to the Trackit Solo. The Trackit Solo has additional USB & Network ports available for the connection of additional or different approved cameras.

The Trackit Solo is lightweight and durable. It possesses a shoulder strap and a handle that allows it to be carried.

This allows the Trackit Solo to be moved with the patient. The Trackit Solo is designed such that it can be wirelessly connected to an ambulatory amplifier by clinical personnel, and then used by the patient for the duration of an EEG study in their home or clinical environment. After the study is completed, clinical personnel can disconnect the patient from the amplifier and retrieve the Trackit Solo.

Use with other equipment

EEG amplifier

The patient will be connected to an EEG amplifier during the EEG examination. The EEG amplifier will be connected to the Trackit Solo via Bluetooth or USB to record the data acquired by the EEG amplifier.

Other patient-connected equipment

The Trackit Solo has no patient-applied parts and so when used simultaneously with other patient-connected equipment, for example a cardiac pacemaker or other electrical stimulator, it is unlikely that a safety hazard will arise. However always consult the documentation supplied with the other patient- connected equipment to ensure that all hazards, warnings and cautions are considered before the equipment is used together.

Leakage current

This instrument is designed to comply with IEC 60601-1, the international standard for medical electronic equipment, which specifies the permissible levels of leakage current from individual products. A potential hazard exists in the summation of leakage currents caused by connecting several pieces of equipment together. Because this instrument can be used in conjunction with standard electronic devices, the total leakage current should be tested at regular intervals.

Interference

The Trackit Solo will continue to operate in the presence of radio frequency magnetic fields (RF) and the effects of electrostatic discharges (ESD) and other interference, in accordance with the requirements of IEC 60601-1-2.

However, EEG systems record signals of very low amplitude, and these signals themselves are not immune to the effects of RF, ESD and low-frequency magnetic field interference. Such interference may cause signal artefacts.

The Trackit Solo has internal Wifi, Bluetooth and LTE radios fitted. There are approved industry-standard types which present minimal risk of reciprocal interference with other equipment. However, when the equipment is operated with or without Bluetooth connected, other devices in the vicinity should be moved away or turned off to reduce the likelihood of interference to the equipment or by the equipment.

Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the Trackit Solo, includingcables specified by Lifelines Ltd. Otherwise, degradation of the performance of this equipment could result.

When in close proximity to the Trackit Solo, do not use mobile phones, transmitters, power transformers, motors, or other equipment that generates magnetic fields. Refer to the Appendix for more information.
