A61B 5/022 of 11/11/1994).

The disadvantage of this device is the complexity of the design of the mechanism for installing the sensor over the radial artery, the complexity of the sensor itself for the perception of blood pressure and the complexity of the drive element to the sensor, which ultimately reduces the accuracy of measuring blood pressure.

The closest technical solution for the combination of essential features is a device for measuring blood pressure, comprising a case in the form of a watch case, an element for attaching the case to the user's wrist, on / off elements of the device located on the case, an information indicator of the measured pressure, a pulse sensor located in the case waves with a sensitive element and a unit for analyzing the measured information (EP 0653182 according to Cl. A61B 5/024 of 10/19/1994).

The disadvantage of this device is the relatively low accuracy of measurement, the difficulty of orientation and fixing the position of the sensor on the wrist and the inability to conduct continuous monitoring.

The problem to which the claimed invention is directed, is to create a device with increased accuracy of measurement of parameters, easy to use, and the ability to conduct continuous monitoring.

Figure 7 presents a General view of the pulse wave sensor with a node for pressing the sensor to the radial artery and node for clamping the sensor to the bracelet.

The device comprises a case 1, made in the form of a watch case, an element for attaching the case to the wrist, made in the form of a bracelet 2 with the possibility of adjusting the force of its clamp. A pulse wave sensor 3 is fixed on the bracelet, in the case 4 of which there is a sensing element in the form of a console 5, a flat mirror 6 is fixed on its free end. The pulse wave sensor 3 is also equipped with a fiber-optic transducer 7 for bending the sensitive element. On the outer surface of the sensing element is fixed the pilot 8.

The node for pressing the pulse wave sensor to the radial artery is made in the form of a screw-nut system, while the screw 9 is placed in the threaded hole of the cover 10 of the case 4 of the pulse wave sensor 3. On the watch case 1 there is an information indicator made in the form of a rotary screen 11 with a tuning indicator pulse wave 12. The indicator 12 has three colors (red, yellow and green) and responds to the amplitude of the pulse wave. Red color - the signal is insufficient for shooting, yellow - you can work, green - a steady large signal.

The device also contains an electronic unit 13 connected to the memory unit 14 and a unit for analyzing the measured information, comprising an optoelectronic module 15, a low-pass filter 16, an analog-to-digital converter 17, a processor 18, a screen 19 and a voice information indicator (not shown in the drawings). The memory unit 14 is connected to the processor 18 of the measured information analysis unit.

The device is also equipped with a node for clamping the pulse wave sensor 3 to the bracelet 2, made in the form of an adjusting screw 20, located in the slot 21 of the bracelet 2 and fixed in the screw housing 9 of the node for pressing the pulse wave sensor to the radial artery.

The device operates as follows.

After placing the device for measuring blood pressure on the hand, for example, the left hand and fastening the bracelet 2, the position of the pulse wave sensor 3 in the bracelet 2 is adjusted. This operation is carried out using the adjustment screw 20 when the screen 11 of the device is tilted when it is operating in the tonometer mode. When the adjusting screw 20 is unscrewed and displaced along the slot 21, the pulse wave sensor 3 is positioned relative to the radial artery. Checking the correct position of the sensor 3 is carried out according to the shape of the pulse wave, which is visible on the rotary screen 11 of the information indicator, with the correct installation of the sensor of the pulse wave 3, it should be a two-hump (Fig. 4).

After completing the positioning, the pulse wave sensor 3 is pressed against the radial artery by tensioning the bracelet 2 by rotating the screw 9 in the threaded hole of the cover 10. If positioning and tension are selected correctly, the recording mode of the measurement results is automatically activated. In this case, the console 5 under the action of the pulse wave is bent and there is a shift in the vertical plane of the flat mirror 6. In this case, the shape of the pulse wave is determined by the electric signal.

The processed signals using an analog-to-digital Converter 17 from an analog form are converted into a digital and digital signal characterizing the amplitude of the perceived pulse waves of blood pressure, is calculated in the analysis unit of the measured information to obtain the values of systolic and dystolic blood pressure and stress index. The indicated data is displayed on the rotary screen 11.

The presence of the processor 18 and the memory unit 14 allows you to register the time and date of the measurement of blood pressure and memorize it. When lowering the rotary screen 11, the device starts to work in the mode of a conventional electronic clock.

This device allows a comfortable method to effortlessly monitor blood pressure, measure heart rate and stress, and take preventive measures to prevent a vascular accident. The device can be equipped with a voice indicator that increases the comfort of perception of information.
