A61M 31/00

US Classification:

604500000, 604506000

Abstract:

An applicator that has an elastic band to snap a microneedle array against the skin with a predetermined force and velocity. The microneedle array, which may be pre-loaded with drug(s), is attached to the elastic band such that the band can be secured in place (e.g., wrapped around a person's arm), pulled away from the arm, and released from a suitable distance so that the microneedle array snaps back against the arm with sufficient force to cause the intended amount of penetration of the microneedles. Also, a microneedle application device that has an elastic band, a microneedle device, and means for attaching the band to the microneedle device.
