Abstract:
1. A needle electrode comprising a base element, a needle element mounted on said base element, connection means for connecting said needle electrode to external electronic equipment, and a cover element which is displaceable between at least two positions: an “active” position where the tip of the needle element is exposed and a “secure” position where the tip of the needle element is hidden within the cover element, wherein the needle electrode has at least two different active positions where different lengths of the needle are exposed, and the needle electrode is arranged such that the needle element, due to frictional or locking engagement between the base element and the cover element, is prevented from displacing from any of its positions with respect to the cover element during insertion of the needle into a patient's skin, wherein the cover element comprises a hollow cylinder with at least one slot arranged in the side of the cylinder along at least a portion of a longitudinal axis of the cylinder, wherein the base element is arranged inside the cylinder, and wherein the connection means are accessible through said slot.
