Abstract
A microneedle for intradermal injection or diagnostics, constructed as a protrusion above a substrate and whose shape is defined by a pair of vertical side surfaces, configured to be symmetrical about a vertical plane of symmetry and to meet along a vertical leading edge, and by an inclined surface, intersecting the side surfaces, the microneedle also including a vertical bore, located centrally between the two side surfaces and substantially near the leading edge, wherein each of the side surfaces is divided, sequentially along the front-to-back direction, into at least two contiguous planar segments, forming pairs of corresponding segments along the respective side surfaces; each pair of corresponding segments mutually form an acute angle, the angle being between 40 and 70 degrees for the pair of segments adjacent the leading edge and less than 35 degrees for the pair of segments farthest from the leading edgeand wherein the leading edge is formed so that its profile includes an arc, joined to the side surfaces.
