DEVICE FOR NON-INVASIVE DETERMINATION OF HAEMOGLOBIN CONCENTRATION IN BLOOD AND METHOD FOR NON-INVASIVE DETERMINATION OF HAEMOGLOBIN CONCENTRATION IN BLOOD Russian patent published in 2024 - IPC A61B5/1455 A61B6/02 G01N21/01 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely to clinical and laboratory diagnostics, and can be used for non-invasive determination of haemoglobin concentration in blood using a colorimetric method and/or a diffuse imaging method with spatially structured light. Device includes measuring modules for colorimetric measurement and measurement using a diffuse imaging method with spatially structured light of the object of study – a portion of the skin of the patient's hand and nails, a control computer and a power supply unit for autonomous operation. Methods allow using the colorimetric method and/or the diffuse imaging method with spatially structured light for determining the blood haemoglobin concentration using the disclosed device.

EFFECT: group of inventions enables more accurate determination of the patient's blood haemoglobin level by using non-invasive methods: a colorimetric method and a diffuse imaging method with spatially structured light with the possibility of their combination.
