The invention relates to medical technology, namely to devices for measuring blood pressure, and is an improvement of the invention according to the author. No. 1364293.

The aim of the invention is to improve noise immunity.

The drawing shows a compression cuff for measuring blood pressure, a general view.

The compression cuff for measuring blood pressure contains a pneumatic chamber 1, a cover 2, a fastener 3, a remote main 4 and an additional 5 pulse sensors, respectively, with limiters 6 and 7 pulse noise, and a proximal additional pulse sensor 8 in limiter 9 pulse noise. Sensors 4 and 5 are at an equal distance from the distal end of the cuff for measuring blood pressure. The sensor 8 is located at a much greater distance from the distal edge of the cuff. The flanges 10 and 11 of the stops 6 and 7 are rigidly connected.

As the camera 1, the cover 2, the fastener 3, the sensors 4, 5 and 8, for example, the cuff U44447.001 and the DTK-1M sensors can be used. In the manufacture of limiters 6 and 7 of polyethylene, the connection of flanges 10 and 11 can be accomplished by welding. However, to avoid fracture of the seam from the flexible deformation during repeated dressing and cuff removal, the connection of the flanges 10 and 11 can be made hinged.

The compression cuff is used as follows.

The pulse sensors 4 and 5 are fixed in the limiters 6 and 7, the sensor 8 is in the limiter 9. Next, the sensors 4 and 5 and the limiters 6 and 7 are assembled in the distal part, the sensor 8 and the limiter are assembled.

9 - in the proximal part of the cuff on the pneumatic chamber 1 or, for example, in the pockets of the cover 2. The blood pressure measurement cycle is performed. However, limiters 6, 7 and 9 isolate the sensors 4, 5 and 8 from the pressure pulsations in the pneumatic chamber 1, limiter 9 reduces the displacement of the sensor 8 towards the pneumatic chamber 1 when exposed to a useful signal from the vessel, the connected flanges 10 and 11 of the limiters 6 and 7 significantly reduce the offset located above the vessel of the sensor 4 in the direction of the pneumatic chamber 1, the sensor 5, located away from the vessel, affects significantly less energy from the vessel. This therefore provides an increase in noise immunity during the measurement.
