Device for determining oxygen saturation in the blood of an individual, the method to determine the oxygen saturation in the blood of an individual, and the computer program

摘要

Summary device for determining oxygen saturation in the blood of an individual, the method to determine the oxygen saturation in the blood of an individual, and computer program of the present invention refers to a device and a method for determining the oxygen saturation. The blood of an individual.The device proposed comprises an interface (32) for receiving a data stream (26) derived from electromagnetic radiation detected (16) emitted or reflected from one or more portions of the skin of the individual (12), and the said data stream (26) comprises a signal: The per pixel of the skin to a plurality of pixels of the skin of said one or more portions of the skin.A data signal that represents the electromagnetic radiation detected (16) emitted or reflected from the respective pixel of skin over time, an analyzer (34) to determine the change in oxygen saturation in the blood of the plurality of pixels based on the signs of skin Data from said plurality of pixels in the skin.A picker (36) for selecting a group of pixels of the skin which comprises both the pixels of skin showing the change more rapidly in the saturation of oxygen in blood, as the said plurality of pixels of the skin, except for the pixels of skin showing the change more slowly on satur The action of oxygen in the blood.And a processor (38) to determine oxygen saturation in the blood of the individual based on the data signals of the selected group of pixels of the skin. 1 / 1
