Abstract
A reusable electrode holder and associated disposable electrode unit are provided. The holder retains the electrode therein and is connectable to a vacuum source for holding the electrode against a patient's skin with vacuum suction. The holder is also connectable to an electrical lead for connection to the electrode unit. The holder has a resilient cap which is moveable to actuate a valve to open communication through the holder from the vacuum source to a chamber adjacent the skin. To prevent the transfer of contaminants from the skin to reusable parts of the holder, a first contaminant absorber is provided within a housing of the holder and a second contaminant absorber is provided as part of the electrode unit. A second valve can be provided which is actuatable to close vacuum communication when second absorber expands to a threshold contamination condition.
