PURPOSE:To enable uniform sampling of blood sanitarily free from skill of sampling without accompanying pains by performing a pinpoint irradiation of the surface of skin with a laser beam having a specified wavelength, a pulse width and energy to obtain blood at an irradiation point. CONSTITUTION:A resonator 1 has a solid laser inside and is built into the body 2. A power source and a controller are provided on a separate controller 3. A lens hood 4 is provided on the output side of a laser beam of the body 2 and a condenser lens 5 is provided inside the lens hood 4 to condense the laser beam to be outputted from the resonator 1 with the condenser lens 5. Thus, a pinpoint irradiation of the surface of skin is performed with the laser beam having a wavelength of 1.5-3.0mum, a laser pulse width of 100-300usc., an energy of 1-1.5J/pulse to obtain blood at an irradiation point. |
