OPTOELECTRONIC INFRARED SENSOR OF PULSE WAVE Russian patent published in 2008 - IPC A61B5/24 

FIELD: medicine.

SUBSTANCE: optoelectronic infrared sensor of pulse wave contains general constructive basis with two cylindrical air channels located at an acute angle to each other, infrared light-emitting diode is placed close to the point of their mutual interaction in first cylindrical channel, gauge is structurally realised so that hemisphere from optically transparent material is used as constructive basis, infrared differential photo diode is placed in second cylindrical air channel and together with infrared light-emitting diode it is placed on the opposite side of cylindrical air channels relative to the point of their mutual position, and the infrared differential photo diode has rotation degree about the axis and is placed so that its cross-section axial line coincides with longitudinal axial line of hemisphere.

EFFECT: provision of possibility of control under phleboid level of blood-groove against capillary level.
