Abstract
Official abstract text for this publication.
A microneedle array in accordance with one embodiment comprises at least a first microneedle and a second microneedle that are inclined with respect to a support face. A tip of the first microneedle points in a first direction, and a tip of the second microneedle points in a second direction different from the first direction. The first microneedle in contact with skin is stuck into the skin while being moved along a surface of the skin in the first direction. The second microneedle in contact with the skin is stuck into the skin while being moved along the surface of the skin in the second direction.
First claim
Opening claim text (preview).
The invention claimed is: 1. A microneedle array comprising a first line composed of a plurality of first microneedles that are inclined with respect to a support face; and a second line composed of a plurality of second microneedles that are inclined with respect to the support face, wherein the first line and the second line extend radially, and wherein directions in which both the plurality of the first microneedles and the plurality of the second microneedles point are unified into a clockwise direction or a counterclockwise direction, and wherein tips of the plurality of the first microneedles point in a first direction and tips of the plurality of the second microneedles point in a second direction different from the first direction, and wherein the first microneedles in contact with skin is stuck into the skin while rotationally moving in the first direction along a surface of the skin, and the second microneedles in contact with the skin is stuck into the skin while rotationally moving in the second direction along the surface of the skin. 2. The microneedle array according to claim 1 , wherein each of the first line and the second line is arranged along an arc. 3. The microneedle array according to claim 1 , wherein at least one of the plurality of first or second microneedles positioned in a center portion of the support face is longer than at least one of the plurality of first or second microneedles positioned in a peripheral portion of the support face. 4. The microneedle array according to claim 1 , wherein at least one of the plurality of first or second microneedles positioned in the center portion of the support face is shorter than at least one of the plurality of first or second microneedles positioned in the peripheral portion of the support face. 5. The microneedle array according to claim 1 , wherein an inclination angle of at least one of the plurality of first or second microneedles positioned in the center portion of the support face is larger than an inclination angle of at least one of the plurality of first or second microneedles positioned in the peripheral portion of the support face. 6. The microneedle array according to claim 1 , wherein the support face includes a first support face and a second support face positioned outside the first support face, and after at least one of the plurality of first or second microneedles positioned in the first support face starts to be rotationally moved, at least one of the plurality of first or second microneedles positioned in the second support face starts to be rotationally moved. 7. The microneedle array according to claim 1 , wherein the support face is convex.
