It is not recommendedto mix old and new electrodes during use. This is because the conductivity and sensitivity of the electrodes may decrease and wear out over time. Using old and new electrodes may result in inconsistent measurements and incorrect results.

It is best to replace electrodes on a regular basis to ensure that they are always in good condition and provide accurate measurements. However, if you need to use old and new electrodes together, make sure that the electrode type and material drainage area are identical to minimize the risk of measurement errors. Before use, make sure that all electrodes are clean and free of gel residue

We recommend that you do not use different materials for the discharge surface of the electrode. 

Clean the electrode after each use with a damp cloth and a mild detergent. Do not immerse in cleaning solutions/liquids. Do not use do not use automatic cleaning devices or cleaning machines.

After cleaning, the bridge electrode is disinfected by means of wipe dis infection with a disinfectant suitable for surface disinfection of non-invasive medical devices - Do not use agents containing alcohol, peroxide, phenols and potassium permanganate for this purpose.

Yes, the covers must be changed after each use! Covers are a disposable product. These can therefore disinfected which can lead to cross-contamination in the event of multiple use, for example.

They can also be used without covers and instead with contact gel derive.

Note that after each derivation the surface of the electrode cleaned after each discharge, as residues impair the discharge.

Cleaning must be carried out after each use with a damp cloth and a mild cleaning agent take place. Gel residues can be removed with a soft brush can be removed. Do not place the plugs in liquid. The electrodes are not suitable for automatic cleaning devices.

In order to maintain the functionality and service life of the hoods, it is important to maintain the hoods according to the manufacturer's operating instructions.

Gel residues must be regularly removed from the hood and electrodes, otherwise the material loses its elasticity. Likewise, dried gel forms an
insulation layer on the electrodes, which can lead to artifacts and high impedances.

CAUTION:
To clean the ECI electrode hoods, use only the IVORY brand liquid cleaning agent
.

Other soaps or cleaning agents, especially those used in hospitals,
leave a film on the electrode metal. After just a few washes
, the soap film increases in size and surrounds the electrode. This causes excessively high contact resistances.

How to wash the electrode hood:

Remove the chin straps and wash them separately. (with brush and soap - also possible with 60° in the laundry bag in the washing machine).

Soak the hood in warm soapy water (Ivory E-16, approx. 1ml per 2 liters) for a few minutes.

Make sure that the electrode plug of the hood does not get wet.

Remove the gel residues with a manicure ( E-26 ) or cotton swab, or
cleaning brush (PUL00000) to avoid scratching the surfaces of the electrodes.

Rinse the hood thoroughly.

Dry the hood carefully with a terry towel and/or hang it
to dry. Here, too, you must make absolutely sure that the
electrode plug does not get wet or water can run into it.

Then reattach the chin straps to the hood.

In urgent cases, you can dry the hood with a hair dryer.
distance 20 cm to 30 cm and medium temperature level. Too much heat can damage or permanently destroy the material of the hood.

The hood is functional even when still wet.

Check the electrode discs regularly for gel residues and remove them thoroughly.

The Multicap and electrodes must be cleaned after each use. The dried gel forms a layer that prevents the achievement of optimal electrode impedance and qualitative EEG conduction. The FLAT and FLAT PRO electrode hoods can be cleaned without removing the electrodes from the hood. For cleaning the BASE and ELECTRODE SET electrode hoods, it is recommended to remove the MS-E-Base electrodes from the fixed rings.

After draining, carefully remove the hood from the head. For cleaning, place the hood in lukewarm water (drinking water quality) with a drop of cleaning emulsion to degrease and remove gel residues. A soft brush can also be used for this purpose.

NO LACE and USE METALLIC OBJECTS!

Then rinse the hood under running water (drinking water quality). Always make sure that the connecting plugs do not come into contact with water, otherwise they will corrode and contact problems may occur. It is best to hang both the hood and the connector next to each other at the same height on a hook to prevent liquid from entering the connector. Cleaning should take place immediately after use. Dried gel residues but also the cleaning emulsion can form an insulator, preventing the achievement of optimal electrode impedance and a high quality EEG. Therefore, please follow our recommendations so that you can also enjoy your hood for a long time.

To dry, carefully wrap the hood in a towel and lightly blot the hood. This removes the moisture and the hood can be used again immediately. Neoprene is a water repellent material, so only the hood surface will remain slightly clammy. Please store the hoods hanging.

Attention: It is essential to avoid liquid penetrating the plugs or the collector plug of the electrodes!

Preparation of the scalp is important because it can affect the quality and accuracy of EEG measurements. A properly prepared scalp can help the EEG electrodes adhere better and reduce electrical resistance, making measurements more accurate and reliable.

Hair removal: Removing hair from the area around the electrodes to be placed helps to facilitate the application of the electrodes and ensure that they adhere well.

Cleaning: Cleaning the scalp of dirt, oil and other debris before attaching the electrodes helps maximize electrical conductivity and minimize interference.

Removing the horny layer: Removing the horny layer of the scalp by gentle scraping or peeling before attaching the electrodes increases the adhesion of the electrodes and the signal quality.

Remover is used by most users to remove the Collodion.

The users generously moisten the additionally applied "plasters" with the aid of a syringe and blunt cannulas. In some cases, they also pierce the pre-punched holes and try to moisten the attached "plaster" from below. Then the patient's head is wrapped with a towel and the whole thing is left to soak in for about 30-45 min. In this way, most electrodes can be removed wonderfully easily.

To remove residues of SAC2 paste or electrode paste, we recommend that you moisten a cloth with lukewarm water to remove the adhesive residues.

Determination of brain death requires the performance of specific neurological and neurophysiological tests aimed at verifying the functioning of the brain and spinal cord. One of the most common methods for determining brain death is to perform electroencephalograms (EEG).

EEG electrodes are applied to the patient's scalp and measure the electrical activity of the brain. Brain death is confirmed when the EEG shows a flat line with no brain activity.

There are different types of EEG electrodes such as scalp needles that can be used to perform brain death determination, most of them are Ag-AgCl electrodes, these are particularly suitable because they have good conductivity and long life.

In principle, artifacts can never be completely ruled out, since many factors such as error possibilities on the device itself, biological artifacts (e.g. ECG, tongue and jaw movement, sweat, trembling or even eye movement) or technical artifacts (e.g. pacemaker, AC voltage or also high or low frequency interference from cell phones etc.) have and can have an influence.

Equipment faults can usually be reduced by a preliminary check; in the case of biological artifacts, detailed patient education and comfortable positioning of the patient in rooms with normal temperature serve to eliminate the greatest number of faults. In the case of technical artifacts, malfunctions largely result from defective accessories. Therefore, a new set of electrodes should always be available.

A check of the discharge electrodes to see whether they have been carefully applied should be carried out in advance. If this does not correct the error, it is advisable to degrease the discharge surface again using alcohol or acetone and then lightly roughen it with an abrasive paste such as our NEURPREP to remove impurities and dead cells.

The shelf life of gels and pastes may vary depending on the type of product and storage conditions.

To maximize the shelf life of gels and pastes, they should be stored in a cool and dry place, away from direct sunlight and heat sources.

If the product starts to dry out or lose its conductivity, you should stop using it and replace it with a new product instead.

There are several reasons for using an adhesive electrode as the ground compared to a needle electrode:

Safety: Adhesive electrodes are safer to use than needle electrodes because they pose no risk of injury or infection.

Convenience: Adhesive electrodes are easier to use than needle electrodes because they do not need to be inserted into the skin. They can be easily applied to the skin and removed.

Accuracy: Adhesive electrodes typically provide higher accuracy than needle electrodes because they compensate for the electrical resistance of the skin, minimizing signal interference.

Flexibility: Adhesive electrodes can be applied to different parts of the body, while needle electrodes usually need to be placed in a specific location.

Corkscrew electrodes with shield are a special type of electrodes used for performing EEG examinations. They have an advantage over other types of EEG electrodes, such as Ag-AgCl electrodes, which are commonly used.

Reduction of electrical interference: The shield on the top of the corkscrew electrode helps reduce electrical interference from external sources such as electrical equipment and light sources, which improves the accuracy of EEG measurements.

Convenience: Corkscrew electrodes with shield allow the electrodes to be comfortably placed and fixed on the head without slipping or falling off.

Precision: Corkscrew electrodes with screen allow to isolate the EEG signal from a specific region of the brain, which increases the precision of measurements.

Easy to use: corkscrew electrodes with umbrella are easy to use and handle, and can also be easily placed on the scalp.
