Ambulatory EEG and Sleep

Lifelines Neuro Trackit™ has been designed at the outset with both Ambulatory EEG and Sleep applications in mind. Its small and compact footprint, when coupled with the paediatric backpack, makes the Trackit™ ideal for EEG recording applications in children and adults.

Key features include:

USB cable connection to the PC
Optional internal wireless module for Class 1 Bluetooth connection the PC
Long recording times up to 96 hours with 3 Li 9V batteries
Various battery options including Li rechargeable battery packs
PC recording software for EEG and Video EEG monitoring.
Dual recording capability to both the Trackit and the PC simulataneously

Overview

Trackit™ is available in 4 major configurations:

Trackit™ 24

for applications in Ambulatory EEG
(24 unipolar+ 4 AUX DC)

Trackit™ 32

for applications in Ambulatory EEG
(32 unipolar+ 4 AUX DC)

Trackit™ 24P

for applications in Ambulatory EEG and sleep
(20 unipolar+ 4 unipolar/Poly + 4 AUX DC)

Trackit™ 18/8

for applications in Ambulatory EEG and sleep
(18 unipolar+ 8 unipolar/Poly + 4 AUX DC)

All the models above are available with an internal wireless module as an alternative to a cabled PC connection for setup and monitoring of waveforms.

Optional software is also available for Trackit™ recorders including the Trackit™ plus with video.

Benefits

Trackit™ can be worn unobtrusively for ambulatory EEG recordings, ensuring complete patient acceptance. Size does matter!

Flexible recording inputs

With 4 high level DC, 8 bipolar DC polygraphy, and 24 mono-polar EEG ensures that a wide range of monitoring requirements can be addressed. A built in or leaded connector block can be used depending on the…

Data and recording flexibility

Trackit’s unique architecture allows the system to be configured either as an ambulatory recorder with local storage, a headbox with cable or wireless communication to a host computer (Trackit™ Plus software). Trackit also allows a dual recording capability when doing host PC recordings – the EEG data will always be backed up on the Trackits internal flash memory

Trackit™ Blue wireless EEG

Monitor and acquire EEG on the Host PC using the unique Trackit™ Blue (Bluetooth class 1) internal wireless module. Automatically switches to Ambulatory mode when out of range. Dual PC and Trackit recording is also allowed.

Robust and tamper proof

The use of a strong metal box, a lockable battery bay and the use of plug-in batteries means that long recordings can be made with more confidence.

A wide range of sampling rates

Sampling rates from 1 – 256Hz with independent sampling on selected channels (Poly and AUX only) ensures application flexibility, especially when monitoring patients with sleep disorders. 512Hz sampling is available on certain channels for sleep applications (EMG).

Signal integrity

The use of a metal box and high quality amplifier components means that Trackit™ is perfectly at home in the harshest of recording environments.

A safe recording medium

The use of Compact Flash disks ensures complete data integrity for long recordings. Compact Flash disks are more reliable than hard disks; they consume less power, resulting in longer recording times. Compact Flash is a future proof technology – a safe investment.

Removable battery compartment

A removable battery compartment ensures fast and simple removal and replacement of batteries. Select from either disposable or rechargeable batteries.

96-hour recordings

Trackit™ has been designed at the outset as a 24-hour recorder with the maximum number of EEG channels selected at EEG sampling rates <256Hz. 96 hour recordings are possible using 3 Li batteries and a 4GB compact flash card (21ch).

A completely open data format

Trackit™ stores and transmits data in European Data Format (EDF). As a consequence, data generated by Trackit™ is compatible with any commercially available EDF file, including the most popular EEG and Sleep analysis software on the market today.

Ease of operation and set-up

Trackit™ has been designed at the outset with ease of operation and set-up in mind. A simple user interface with LCD display allows parameters such as time, battery and disk life to be monitored by the technician or patient. A Microsoft Windows set-up program allows recording parameters to be configured and loaded onto the device and recordings to be made while connected to the host computer.

Easy annotation of patient events

An event button is available for the patient to time stamp points of interest during the recording, allowing faster data reduction and review by the physician.

Convenience

A built in impedance check and calibration means that no extra hardware is needed when setting up the device. It is also possible to interrogate impedance values from the device during a recording.
