Abstract

A laser perforator (10) for perforating skin (36) of a patient and obtaining of blood samples consists of laser light source (12) for producing an output laser beam, a focusing arrangement (14) for focusing the output laser beam at a skin area selected for perforation, a guiding arrangement, a power supply unit (16) and a retaining arrangement (18) for retaining the skin area. The retaining arrangement (18) is formed to intensify blood circulation in the skin area selected for perforation.
