摘要：
The invention relates to medical devices intended for functional non-invasive diagnosis of cardiovascular system of the patient. The apparatus comprises two sensors, analog-to-digital signal converter and a unit for collecting, processing, display and data transmission. Each sensor includes a sensor element structure with a coplanar strip transmission line forming the working channel encoder, an asymmetric stripline transmission line signal forming the reference sensor channel, the hub of electromagnetic energy and a dielectric substrate (1). On one surface of the substrate (1) applied to an electrically conductive ground plane (2) and the printing path (3) of the working channel. On the opposite surface of the substrate coated printing track (4) of the supporting channel. Electromagnetic energy concentrator is formed as a conductive shield (5) mounted on the ground plane layer (2). The screen (5) forms a closed structure around the printing track (3). When using a screen (5) reduced dimensions of the sensor sensitivity zone to a controlled portion of the skin of the patient cover sizes. The screen (5) can be electrically isolated from the ground plane (2), or electrically connected thereto. The screen (5) formed as a thin-walled rectangular box shape. The height of the screen (5) is selected in the range of 0.5 to 10 mm, and a thickness - of 0.1 to 1 mm. As the screen material (5) is used copper or copper alloy. The technical result is to increase the accuracy of determination of the pulse wave velocity and ensuring the reliability of the measurement results by improving the noise immunity of repeated reactions sensors and sensors from false positives caused by the movement of tissue and blood vessels near the controlled portions of the arteries. 7 ZP f ly-2-yl.Полезная модель относится к медицинской технике, предназначенной для функциональной неинвазивной диагностики сердечнососудистой системы пациента.
