Electrode element for attachment to human body to pick up signals for electrocardiogram uses suction cup with flexible lips, incorporating flat plate with array of projecting electrodes

摘要

The electrode plate (16) is circular and generally flat, with an array of shallow projections, with a maximum height of between 0.1 to 2 mm, to make contact with the skin. The suction cup (18) surrounds the electrode and has an inner fastening rim (42), a flexure (44) and a sealing lip (46) engaging a groove (26) in a shoulder (24) on a housing (10). The suction cup has a flexure (48) joining the sealing lip to a conical or bowl-shaped portion (50). A flexure (52) at its outer edge joins it to an inward-extending lip (54). There is a connection for a suction hose (20).
