技術說明

本發明為一種影像式血氧濃度的檢測裝置及方法，該方法包含下列步驟：提供發射複數道交替出現並均勻分佈的紅光與紅外光，其中該選定皮膚區域具有複數個座標點；控制該複數道紅光與紅外光輪流照射至該選定皮膚區域上，以具有一紅光期與一紅外光期；接收反射自該皮膚區域上之複數道紅光與複數道紅外光；及分析計算該複數道經反射之紅光與紅外光之光強度，以得到該選定皮膚區域上各座標點之一血氧濃度指數，並建立血氧濃度分佈。藉由本發明之裝置及方法，血氧濃度之測量較不受外界訊號強度與人體末稍循環不良之影響，且可單次完成皮膚表面大面積的測量。 The present invention provides an image based oxygen saturation measuring device and method thereof. The method comprises steps of providing a plurality of red lights and a plurality of infrared lights arranged uniformly and alternatively and turned on alternatively, the selected skin area having a plurality of coordination points; controlling the plurality of red lights and infrared lights to incident onto the selected skin area of a testee to have a red light turn-on period and an infrared light turn-on period; receiving a reflected version of the plurality of red lights and infrared lights from the selected skin area; and analyzing the plurality of reflected red lights and infrared lights to acquire an oxygen saturation index with respect to each of the coordination points. By means of the present invention, the measurement of oxygen saturation may be much exempted from effects brought from exterior interference and poor blood circulation.
