ABSTRACT:
A perforating device for dermal administration of medicine is disclosed. The device includes skin perforating members provided with a plurality of needles and received in a casing. The skin perforating members have alternately arranged needle discs and spacer discs which easily and evenly perforates the skin to a depth, suitable for dermal administration of medicine, by simply rolling the assembly on the skin. The device also includes a biasing mechanism for elastically vertically moving the assembly during skin perforating and thereby preventing the skin perforating members from excessively perforating the skin. The device informs the user of the excessive pressure of the assembly and thereby preventing possible skin damage.
