Claim:
A laser skin perforator comprising: a laser light source for generating an output laser beam, a focusing arrangement for focusing the output laser beam at a skin area selected for perforation, a retaining arrangement for retaining said skin area, said retaining arrangement being formed to intensify blood circulation within said skin area selected for perforation and a device for preventing an accidental activation of the laser source when said laser skin perforator does not engage said skin area; said device including a forwardly positioned engaging cup comprising a plurality of independent engaging segments slidably arranged along a longitudinal axis thereof, a distal portion of each said segment forming a part of a switch operable between open and closed positions thereof, wherein in the open position of the switch the distal portions of engaging segments are spaced from a conductive plate positioned rearwardly of the engaging cup, so as to disconnect electric supply from said laser source, and in said closed position the distal portions of the engaging segments engage the conductive plate so as to activate the electric supply.
