WaveGuard Connect - 19 Channel EEG Cap

WaveGuard Connect’s exceptional comfort is achieved through the use of soft silicone electrode cups instead of the hard, uncomfortable plastic cups that are commonly used in competing caps

WaveGuard Connect EEG caps feature hidden wiring and high density connectors, making the use and maintenance of the caps quick, safe, and easy. They're perfect for routine diagnostics where good signal quality is crucial for valid assessment.

Maximum comfort for patients

The breathable Coolmax™ fabric in combination with soft silicone electrode cups ensure comfortable fit over extensive periods of time. While being soft to the skin, the durable fabric includes an effective fiber-based moisture management system which takes care of derivation of perspiration away from the body in warm environments. The soft electrode rings lessen the pressure from the electrode sensors, which is essential in reducing skin irritations that are caused by many other available EEG caps in the market.

Optimal signal quality

Tin has been widely used for many years in clinical and research areas with good longevity and signal quality. It is the most commonly used electrode sensor material in clinical applications as it has proved to be very reliable in AC coupled clinical recordings with frequency range higher than 0.5 Hz. waveguard connect electrode sensors are made of pure, solid tin which provide the user with optimal signal quality at all times.

Quick and easy application

All cap electrodes are pre-positioned according to the international 10/20 system. Thanks to the pre-positioned electrodes, the application of the caps is easy and the preparation time for each patient is significantly reduced as compared to placing each electrode individually. The entire procedure from preparation and gelling to recording is achieved in less than 10 minutes!

Straightforward connection

The waveguard connect caps are compatible with all major EEG amplifiers used in clinical environments, such as NicoletOne and Mitsar. The EEG caps come by default with a D-SUB 25 connector for a quick and straightforward connection. A D-SUB to single point touch-proof adapter can be additionally purchased for interaction with other third-party amplifier head-boxes.

WaveGuard Connect EEG Cap Frequently Asked Questions

Q: How many times can I reuse my WaveGuard Connect cap?
A: The number of times that a cap can be used with all electrodes intact and without compromising signal quality depends upon many factors. Careful handling and thorough cleaning are most important. The electrode sensors, the fabric, and all other parts and materials have been selected and designed to reach more than 500 cycles of recording and cleaning.

Q: What is the main difference between Tin(Sn) and Ag/AgCl electrodes?
A: When selecting sensor material for EEG electrodes, the most important aspect is its ability to withstand corrosion and preserve conductance. Tin and Ag/AgCl-Electrodes have been widely used in clinical and research areas with overall good longevity and signal quality. However, tin electrodes tend to attenuate low frequencies more than Ag/AgCl electrodes. Other sources have found no difference between these two electrodes especially for measuring ERPs and SCPs . It's widely agreed, that the filtering caused by the electrode is no more severe than the typical filter setting of an EEG amplifier. Either tin or Ag/AgCl electrodes are adequate for clinical use, but Ag/AgCl may be preferred when very slow potentials are being recorded. 

Q: What are the advantages of an EEGcap with pre-positioned electrodes over loose electrodes?
A: The pre-positioned electrodes are positioned following the international standard 10/20-System. This is the most usual montage setting and covers the frequently used electrode positions. Due to the pre-positioned electrodes in WaveGuard Connect, the preparation time for each patient is significantly reduced. The WaveGuard Connect electrodes are covered by two fabric layers to guarantee best protection for the electrode body and cables. It increases the longevity of the whole electrode system and saves cost and reduce waste due to less frequent purchasing of equipment supply.

Q: Can the electrodes be removed from the cap?
A: The pre-positioned electrodes of WaveGuard are covered by two fabric layers to guarantee best protection for the electrode body and cables. The electrodes can be manually removed, but then the warranty would forfeit. In case an electrode is not required, just deactivate these electrode channels in the recording and/or analysis software.

Q: Is the WaveGuard Connect cap clinically tested?
A: WaveGuard EEG caps are compliant to the international standards for medical devices. The WaveGuard EEG cap is a medical device CE marked according to EU regulation. In the USA, WaveGuard EEG caps have FDA 510(k) clearance, and in Canada WaveGuard caps are registered as medical device according to the C-MDR.

EEG recording with WaveGuard Connect caps

Q: How can I check if the electrodes are working properly?
A: Before you start recording, make sure all electrodes are functioning properly. A well-functioning electrode will correctly record the EEG signal with low impedance and high Signal-to-Noise-Ratio (SNR). Both parameters can be easily checked in your EEG recording software.

Q: How long can I record data without re-gelling the subject?
A: Once the gel is applied, there is no need to re-gel the subject for at least 6 hours. 

Q: Is it possible to re-gel the electrodes during the experiment?
A: Yes, it is always possible to re-gel, however, it is necessary to pause the recording in order to avoid any needle related artifacts or electrode movement artifacts.

Q: How long can I record with a WaveGuard Connect cap?
A: As the cap is made of breathable fabric and flexible electrode rings, it assures optimal comfort even in long recordings. The recommended maximum duration of a single recording is 6 hours. 

Cleaning and Maintenance

Q: How do I disinfect the WaveGuard Connect cap?
A: Make sure that the cap is adequately cleaned prior to the disinfection procedure. High-level disinfectants are recommended, whereas for your normal clinical use a ‘lower-level’ product may suffice. Consult with your local infection-control officer about acceptable products or allowances in e.g. reduced concentration levels and/or shorter submerging times for the caps. Other than this, the disinfectant’s instructions for use and rinsing must be followed strictly at all times. Plastic parts, such as labels, flex-rings and the fabric, may bleach slightly over time. This is normal and does not interfere with the normal usage of the cap. The use of disinfectant may slightly reduce the normal lifespan of the caps. 

Please note that alcohol is not an adequate solution for disinfecting electrodes. The local and hospital regulations for cleaning should not be neglected in the process and must be followed. For any questions, do not hesitate to contact us.

Q: Can the cap connectors get wet?
A: The connectors must not get in contact with water under any circumstances. Avoid any moisture near the connectors in order to completely prevent possible short-circuits or corrosion. In the event that you need to clean the connectors, use a cotton stick slightly damp with alcohol (do NOT use this on the electrodes).

Q: How long does a WaveGuard cap need to dry?
A: Do not try to wring or squeeze the cap. Gently dab the cap fabric using a towel, or hold the cap between two towels. With the constant breeze of a fan aimed at the cap, drying time should be about 20 minutes.

Q: Can I record data with a wet cap?
A: No. WaveGuard EEG caps must be used only when clean and dry.
