Abstract
Rapid, high-volume, intradermal infusion with minimal pain, is achived by applying an array of 10 to 30 hollow microneedles having a length of greater than 100 um to less than 1 mm into the skin of a patient, with a microneedle spacing of no less than 1.5 mm on average between adjacent microneedles, and pumping greater than 200 uL of fluid through the hollow microneedles at a rate of greater than 20 uL/min.
