Abstract
This invention provides a device and method for perforation of skin for the purpose of drawing blood or administering pharmaceuticals. The device incorporates a laser which produces a laser beam at an appropriate wavelength which is specifically focused to perforate the skin of a patient. Optionally a container can be incorporated in the device for collecion of blood from the perforated tissue.
Claims50
A laser perforator device for perforating skin comprising
- a) a lasing element which emits a pulsed beam;
- b) a power source;
- c) a high voltage pulse-forming network linked to the power source;
- d) a means for exciting the lasing element, linked to the pulse-forming network;
- e) a laser cavity;
- and
- f) a focusing means which focuses the beam from said lasing element to at least one beam shaped as an ellipse at the focal point of the beam.
