Abstract
A lens shield system for shielding a laser source of a system used for collecting capillary blood or fluid from skin, the lens shield comprising a strap apparatus releasably emplaceable around a member of a living being, the member having skin thereon and blood therein, and a lens shield member connected to the strap and disposed for receiving and for transmission therethrough of a laser beam from the laser source directed at the skin. A removable lens shield for shielding a laser source of a collection system used for perforating skin and collecting blood or fluid therein or therebeneath, the collection system in a housing, the lens shield comprising a body sized and configured for removable emplacement in the housing of the collection system between the laser source and the skin, and a window in the body through which the laser beam is transmissible prior to contacting the skin. A method for collecting fluid from a living being has been invented which uses the devices mentioned above. A new laser perforator has been invented for perforating skin with a perforation to permit blood under a surface of the skin to flow out, the perforator in one embodiment having a laser light source…
