SLEEP
Electrode cap SLEEP is the textile cap with pre-installed Ag/AgCl sintered MCScap‑T electrodes with DB‑25M common connector. The electrode cap is designed for use with electroencephalographs and biological signal amplifiers.
Electrode cap SLEEP can be used for general EEG practice, EEG monitoring, PSG, tmsEEG.
Textile cap is made of elastic material, preserving the shape and size. The cap provides the exact position of the electrodes on the head without additional measurements and adjustments. Large holes are provided for ventilation and access to the electrodes and patient’s skin.The cap is fixed on the head with the chin or chest belt. The caps are marked according to the 10-10 system. Size identification is carried out by the color of the material or by the color of the seam.
MCScap‑T is a thin cup Ag / AgCl sintered electrode for EEG recording. MCScap‑T is designed for maximum patient comfort during examination in lying down position, for example, during sleep EEG or for examination of newborns. The design of this electrode is the most preferred for conducting combined TMS-EEG studies. The Ag / AgCl sintered electrode material guarantees minimum polarization and long-term signal stability, as well as an increased electrode life. The conductive surface of the MCScap electrodes is not in direct contact with the skin. Contact is provided by a conductive substance. A hole in the electrodes is provided to add a conductive gel. Use with conductive paste is possible. Electrode have additional labeling what makes easy to rearrange them to new textile base.
