Abstract
The present invention includes an adjustable head set held in place on the back of a patient'"'"'s head when the patient leans back against a chair head rest. The head set includes self-preparing disposable monitors that provide good contact with the patient'"'"'s head without prior skin preparation. The monitors include a conductive tube containing conductive wires, the tips of which form a planar cushion surface for contacting thr patient'"'"'s head through a caratinaceous layer of skin. The monitors are held in adjustable holders that allow the contact force to be adjusted. The adjustable holders are mounted in holder slots of head set springs where the slots also allow adjustment of the placement of the monitors. The springs can include hinges for rotatably adjusting placement of the monitors. The disposable monitors are filled with an electrolyte solution using a disposable applicator including a puncturable film, punctured by a monitor when the electrolyte solution is being applied.
