Vein , artery or other living body for the non-invasive visualization of the object of the subcutaneous tissue and in vivo , or a disposable light source device for monitoring the acceleration of venous insertion and extraction of fluids , biological surface the optically coupled by bonding with , comprises a adaptation layer for adhering the device to the biological part , and a main light source for irradiating the living body leads to near-infrared light through the adaptation layer , disposable light source device . The disposable light source device may also include a light transmitting electrically insulating layer electrically insulates the placed the main light source from said biological contact adaptation layer between the main power supply and the body contact adaptation layer . The disposable light source device also may include a proximity sensor that also the light source to control the operation of the first light source to start only when the adaptation layer is adjacent to the body surface . [ Selection Figure ] Figure 4B静脈、動脈、またはその他の生体の皮下組織および生体内の対象物の非侵襲性可視化のための、または、流体の静脈挿入や抽出の促進と監視のためのディスポーザブル光源装置であって、生体表面と接合して光結合し、前記装置を前記生体部分に接着する適合層と、近赤外光を前記適合層を通して導き前記生体を照射する主光源とを備える、ディスポーザブル光源装置。前記ディスポーザブル光源装置はまた、前記主電源と前記生体接触適合層との間に配置され前記主光源を前記生体接触適合層から電気的に絶縁する光透過性電気絶縁層を備え得る。前記ディスポーザブル光源装置はまた、前記光源が前記適合層が前記生体表面に近接したときのみ起動するように前記第1の光源の作動を制御する近接センサも備え得る。【選択図】図4B
