The invention relates to a method for creating a vein access, particularly on the human body, wherein at first the area of the skin surface (1) surrounding the vein access is disinfected, than the epiderm (3) is penetrated and the vein (4) opened and wherein finally a cannula part (5) is inserted in

The invention relates to a method for creating a vein access, particularly on the human body, wherein at first the area of the skin surface (1) surrounding the vein access is disinfected, than the epiderm (3) is penetrated and the vein (4) opened and wherein finally a cannula part (5) is inserted in the vein (4). Further the invention relates to a device for implementing the method. Thereby the penetration of the epiderm (3) and/or the opening of the vein (4) are performed by a cutting device (6) operating with electromagnetic radiation.

[ I claim:] [1.] A device for access to a vein of a patient by penetration of skin of the patient, comprising:a mounting member provided with means for affixing the mounting member to skin of the patient in proximity to a vein to be accessed;connection means on said mounting member for connection of at least one unit selected from a syringe unit and an infusion unit to said mounting member;a cannula on the mounting member having an end adapted to penetrate into said vein and communicating with said connection means for interconnecting said unit with said vein;a light-conductive cutting element on said mounting member having a sleeve portion surrounding said cannula at least at said end and juxtaposed with the skin of the patient for directing a high-energy light beam of a wavelength in the visible range or a range adjacent the visible range onto the skin to pierce the skin and penetrate the vein, the cannula being insertable through a tubular cut made by said high-energy light beam into the skin and said vein;a source of high-energy light of said wavelength in the visible range or said range adjacent the visible range connected to said light conductive element, and measuring means on said mounting member for positioning said cutting element by photoelectric plethysmography to pierce said vein.
