MICRONEEDLE DEVICE

摘要

A microneedle device for delivery or sampling of fluids to or from intradermal layers of the skin of a mammalian subject includes a skin contact configuration defining an orientation of the device and a number of microneedles. The microneedles are deployed relative to the skin contact configuration so that, when deployed against the skin, a first region of a peripheral surface of the microneedle is deployed roughly parallel to the initial plane of the skin. A fluid flow bore intersects the first region of the peripheral surface.
