Infa-Cap (ECI) Infant Size Single Electro-Caps

Infa-Caps from ECI (Electro-Cap International) are similar to Electro-Caps and are also made of elastic spandex-type fabric and come pre-equipped with recessed, pure tin electrodes attached to the fabric.

Infa-Caps come in different sizes and will fit newborn babies to babies; from ages of 9 to 12 months. Infa-Cap I has International 10-20 electrode placements. Standard Infa-Caps II and III have abbreviated electrode placements consisting of F1, F2, C3, C4, 01,02, T3, T4, Cz and ground. Infa-Cap III can be used for recording premature babies by using E6 Disposable Sponge Disks on all of the electrodes.

Infa-Caps and Electro-Caps are used in a variety of different applications including EEG for LTM (Long-Term Monitoring), PSG (Polysomnography), Ambulatory, Telemetry, and even animal research.

One Infa-Cap per pack.

Application note

1. Connect the Infa-Cap to the electrode board adapter.
2. Place the body harness around the chest and under the armpits of the subject.
3. Fasten the velcro straps together making sure the straps are in front and centered on the chest.
4. Measured the circumference of the head with a special color code tap measure, one inch above the nasion and one inch above the inion. The color-coded tape will indicate the color of the proper cap size.
5. Clip the earclip electrode to the subject’s earlobe.
6. Using a syringe, inject a small amount of Electro-Gel into the disc cavity of the earclip electrodes. Rock the syringe back and forth using moderate pressure. This will abrade the skin and lower the impedance.
7. To ensure proper placement of the electrodes, measure the distance of the nasion and inion to calculate the location of Fpz (10% of the distance between nasion and inion) and mark the location with a marking pen.
8. Measure the circumference of the subject’s head to determine the location of the Fp1 and Fp2 (5% of the circumference left and right of Fpz and mark these locations with a marking pen.
9. Place sponge disks over the Fp1 and Fp2 marks. These will absorb perspiration and reduce motion to the electrodes.
10. Place the Infa-Cap on the subject’s head.
11. Set the Fp1 and Fp2 into the sponge disks on the forehead.
12. Continue to work the Infa-Cap on from front to back until it is tight on the head.
13. Secure the cap straps to the body harness by crisscrossing straps and snapping them into place.
14. Double-check that the straps have been pulled tight and secured. This will reduce movement artefacts during the EEG examination.
15. Work each electrode onto the scalp to move excess hair from beneath the electrode mount. Make sure the Infa-Cap is centered on the head and fits properly.
16. Connect all electrodes to your biosignal amplifier.
17. Fill the syringe with 3-4cc of Electro-Gel.
18. Place two fingers on the electrode holder and with the syringe, inject Electro-Gel while rocking the syringe back and forth using moderate pressure until a small amount of gel comes out of the hole. Wipe off the excess gel from the electrode.
19. Check the impedances and ensure impedances are below 3 kOhms. If the impedance reads above 3 kOhms, the electrode must be refilled and the scalp re-abraded until the impedances improve. If the impedances stay above 3 kOhms, use a Quick Insert electrode which will bypass the electrode on the Electrode Board Adapter.
20. Start the EEG recording.
