Microneedle formulation administration member and microneedle formulation rapid administration device for placement of target substance in dermis

摘要

The object of the invention is to prevent overdose due to repeated administration within the therapeutic range of the skin, and more reliably administer a prescribed amount of growth factor into the dermis of any desired depth of the skin, and to achieve the desired effect To provide a microneedle preparation device that avoids the side effects of pigmentation. The means for solving the problems includes a guide cylinder, a pedestal that is at least partially housed in the guide cylinder and sliding in the length direction, and a drive that drives the pedestal toward the tip of the guide cylinder. A microneedle formulation administration device in which the microneedle formulation is mounted on the distal end surface of the pedestal and the microneedle formulation is pushed out from the distal end portion of the guide tube, the microneedle formulation having a distal end portion. A microneedle preparation having a first part containing a target substance and a second part having a base part and no target substance, wherein the impact pressure against the skin of the distal end surface of the pedestal is 30 N to 200 N per square centimeter It is an administration device.
