Probe electrode cable for medical e.g. electro cardiogram test - uses carbon fibre-impregnated plastic insulating coating as cover, with lead coupled to test equipment

摘要

The electrode comprises a disc of material (1) with a flat ring (1) surrounding a central thickened portion (2). A terminal (3) is formed centrally on the thick part of the electrode. The terminal comprises a stud with a reduced neck which is intended to clip into a corresponding socket (8) in the end fitting (7) of a lead (6). The connection lead is used to link the electrode to an electroencephalograph or an electrocardiograph. The lead is covered with an insulating coating, but is made from a similar material to that of the electrode - for example a plastic with carbon embedded in it such as polythene containing carbon ADVANTAGE - Electrode and lead are completely transparent fibres. ADVANTAGE - Electrode and lead are completely transparent to x-rays and do not interfere with x-ray imaging.
