PROBLEM TO BE SOLVED: To clarify the positional relationship between a specified area which is displayed on a displaying means and an actual specified area of a donor when a vein is displayed by a photographing means and the displaying means by projecting an infrared ray to a living body.SOLUTION: A vein displaying apparatus 10 includes a near infrared LED 38 which projects light including wavelengths of a near infrared ray region to the arm 12 of the donor, a lamp 40 which projects light including wavelengths of the near infrared ray region and a visible light region, a lens 42 which makes the light projected to a spot projection section 100 of a spot shape to the arm 12, a near infrared ray camera 34 which photographs the arm 12, an infrared ray filter 36 which is installed on the front surface of the near infrared ray camera 34 and shields the visible light, and a monitor 20 which displays an image having been photographed by the near infrared ray camera 34.COPYRIGHT: (C)2010,JPO&INPIT【課題】赤外線を生体に照射して撮像手段及び表示手段によって静脈を表示させる際に、表示手段に表示された所定部位と実際のドナーの所定部位との位置関係を明確にする。【解決手段】静脈表示装置10は、ドナーの腕12に対して近赤外線領域の波長を含む光を照射する近赤外線LED38と、近赤外線領域及び可視光領域の波長を含む光を照射するランプ40と、腕12に対して光をスポット形状のスポット照射部100に照射させるレンズ42と、腕12を撮像する近赤外線カメラ34と、近赤外線カメラ34の前面に設けられて可視光を遮蔽する赤外線フィルター36と、近赤外線カメラ34で撮像された画像を表示するモニタ20とを有する。【選択図】図1
