Abstract
A laser perforator for perforating skin of a patient and obtaining of blood samples consists of laser light source for producing an output laser beam, a focusing arrangement for focusing the output laser beam at a skin area selected for perforation, a guiding arrangement, a power supply unit and a retaining arrangement for retaining the skin area. The retaining arrangement is formed to intensify blood circulation in the skin area selected for perforation.
Claims27
A laser perforator for perforating a skin of a patient, the perforator comprising:
- a laser light source for generating an output laser beam, a focusing arrangement COT focusing the output laser beam at a skin area selected for perforation, a power supply unit and a skin retaining arrangement for stimulating blood flow in the area of perforation and for retaining the skin area in such a manner that a contact is formed between the skin area and the skin retaining arrangement, the skin retaining arrangement having a substantially hollow inner space with at least partially flexible wall for adjusting the volume thereof and varying the pressure within said inner space.
A laser perforator for perforating a skin of a patient, the 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 power supply unit,
- a detecting arrangement for detecting an optimal distance between the focusing arrangement and the skin area selected for perforation, and an activating arrangement adapted to activate the power supply unit when the skin area selected for perforation is positioned at the optimal distance from the focusing arrangement, and
- a replaceable engaging cup having a predetermined length, said optimal distance is between the focusing arrangement and a focal point of the output laser beam, said optimal distance is achieved by selection of said replaceable engaging cup having the predetermined length.
A laser perforator for perforating a skin or a patient, the 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 power supply unit, and an optical member having a variable thickness along a longitudinal axis thereof, said optical member is made of a material having predetermined laser radiation transmission characteristics and being positioned between the skin area and the laser source,
- whereby amount of energy delivered to the skin area by the output laser beam is adjusted by movement of the optical member with respect to the output laser beam.
A laser perforator for perforating a skin of a patient, the 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 power supply unit and a skin retaining arrangement for retaining the skin area selected (or perforation, said retaining arrangement being defined by at least a side wall thereof with a substantially hollow cavity developed within the side wall, an engaging aperture provided within the side wall, the skin area protruding through the engaging aperture into the substantially hollow cavity, so that the output laser beam entering the cavity is directed transversely to the protruding skin area facilitating formation of an elongated slit within the skin area.
