WHOLE BLOOD SO2 SENSOR Russian patent published in 2020 - IPC A61B5/1455 G01N21/35 G01N33/49 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment and concerns a sensor system for oxymeter to be used in a whole blood oxygen analyser. Sensor system includes a light-emitting module, a light source housing, a light detector and a cuvette unit. Light-emitting module includes a group of light sources comprising at least two light-emitting diodes (LED) of visible light and an infrared LED having a wavelength range in the near infrared wavelength range. Light source housing is shaped to truncated figure and comprises base, one or more side walls and light-emitting end opposite the base. Group of light sources is located near the base and faces the light-emitting end. On one or more side walls there is a reflecting coating. Light detector is located opposite and at a distance from the light-emitting end of the housing of the light source and faces it. Cuvette unit is located between the light emitting end of the light source housing and the light detector.

EFFECT: technical result consists in ensuring the possibility of analysing whole blood samples and improving measurement accuracy.
