SKIN-PERFORATING MICROPROTRUSIONS SUPPLIED WITH MEANS FOR CONTROLLING THE DEPTH OF PERFORATION Russian patent published in 2008 - IPC A61B17/20 

FIELD: medicine.

SUBSTANCE: the present innovation deals with introducing trasdermal substances and/or sampling the analyzed substances. The suggested device for forming a number of microincisions in animal skin at the preset depth of perforation contains the first element supplied with a great number of projecting skin-perforating microprotrusions, moreover, these microprotrusions are designed with the ability to perforate skin for the preset depth of perforation, and a stopping device of perforation depth interacting with either one or more microprotrusions being located in the preset location between the ending and the surface of a sheet. The stopping device restricts the perforation with microprotrusions for the preset depth. Each microprotrusion contains the surface of a sheet, unperforating part, perforating part with the edge, the ending and frontal surface. Perforating part's length corresponds to L2, and a microprotrusion's length - L1 being the distance from the sheet's surface up to the end of the microprotrusion in question. The innovation provides the chance for more successive, uniform and reliable penetration of the device suggested into body surface and, also, decreased risk for too deep perforation with the microprotrusion.

EFFECT: higher efficiency.
