Method and apparatus for assembling an electrode cap
First Claim
1. Apparatus for assembly of an electroencephalographic electrode cap of the type comprising a generally hemispherical cap of stretchable fabric adapted to provide a close fit to a patient'"'"'s head and a plurality of electrode assemblies comprising at least first and second portions having axial apertures and adapted to snap together with a portion of said fabric between said first and second portions, comprising:
- a block having a shape corresponding generally to a patient'"'"'s head, a plurality of rods each having a first end embedded in said block and a second end extending a short distance from said block, said rods positioned at preselected locations corresponding to desired locations of said electrode assemblies said rods receiving and locating said first portions of said electrode assemblies at said preselected locations,whereby an electrode cap may be assembled by placing said first portions of said electrode assemblies on said rods, positioning a cap over said block, and pressing said second portions of said electrode assemblies onto said rods and into snap engagement with said first portions, respectively.

Abstract
An improved biomedical electrode comprising two snap together portions which may be assembled with a layer of elastic fabric between the two portions. At least one of the portions carries a conductive electrode and a lead for making connection to a recording system. An improved electrode cap comprises an elastic cap carrying a plurality of the snap together electrodes. An improved method of assembly includes the use of a generally head shaped block having a plurality of rods extending from the surface to hold one portion of the electrodes while the elastic cap is stretched over the block so that the rods may be used for alignment of the electrode second portions with the first portions and allow the assembly to be snapped together and simultaneously permanently mounted on the cap.
