System for the measurement of the content of a gas in blood, in particular the oxygen saturation of blood

摘要: The system comprises a mounting device and two holding members detachably fastened to the device, each member comprising measuring head. Each head light receiver sources adapted emit signals at various wave lengths least one heat radiator bodily region, particularly skin region in which oxygen saturation of blood is measured, by irradiation waves. If heads are positioned during measurement on opposite sides part be examined, then will able receive reflection dispersed back from as well transmission permeating through part, thus yielding good accuracy. power output waves emitted controlled pulse width control way have parameter representing measure for heart cause changes intensity coming out body reaching receivers so predetermined desired value. An adequate heating guaranteed, without any tissue damages occurring due overheating.
