ELECTRONIC SPHYGMOMANOMETER Russian patent published in 2015 - IPC A61B5/22 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. An electronic sphygmomanometer contains a cuff, a unit for air filling and release, a pressure detection unit and a unit of arterial pressure calculation. One or two sensors of the pressure detection unit of are located on the first main surface of an internal circuit board. Air channels of the pressure sensors protrude on the second main surface, which is an opposite side of the internal circuit board from the first main surface. An air tube of the pressure sensors is connected with air channels. A branching air tube branches from a cuff air tube and is connected with the air tube of the pressure sensors. The air tube of the pressure sensors has connecting heads of the first and second air channels respectively, connected with the first and second air channels respectively. The internal circuit board has the first and the second protecting plates, which are located at the specified distance from the second main surface and in which respectively provided are the first and the second holes, which bring the first and the second air channels respectively on the side of the second main surface. At least one protruding element of the connecting heads of the first and the second air channels respectively mesh with the internal surface of the protective plates in the holes, when external surfaces of the connecting heads are connected with the air channels.

EFFECT: application of the inventions will make it possible to increase the accuracy of arterial pressure measurement.
