Specialists from the MEPhI Institute of Cyber Intelligence Systems and Engineering centre have offered a device, which allows conduct distant daily monitoring of patient’s blood pressure. The suggested device will be more autonomous in comparison with analogues, will become more convenient and effective for use in ambulatory conditions, at the same time there will be a possibility of one-time measuring of blood pressure and real-time distant monitoring by a specialist.

Blood pressure is an important health indicator; human well-being and health often depend on it. But there are situations when one-time measuring of this indicator is not enough. For the past ten years there have appeared methods, which allow constantly measure the level of blood pressure – ambulatory blood pressure monitoring (ABPM).

There are many systems of pressure monitoring, which contain a device for measuring pressure, control unit, and memory, where measuring is stored. The disadvantage of such systems is that the data is stored on a special device, and there is no possibility to give it to the doctor straightaway, which doesn’t allow monitor the patient’s state in real time.

What’s more, modern devices have disadvantages, which limit user’s convenience. For example, the process unit is spaced apart from the measurement unit, so the user has either to be constantly in the bond distance with the processing unit or to carry it everywhere. Otherwise the device has to have a lot of nutrition elements, which leads to the enhancement of the device mass and inconvenience for the user. Or it may not contain an autonomous system of emergency depressuring, which requires constant control on behalf of the user, and others.  

The device for blood pressure monitoring, suggested by MEPhI specialists, is highly autonomous, which allows make the procedure of 24-hour monitoring more convenient for the patient: he can do his daily routine during the monitoring. The device uses oscillometric method of pressure measuring with step-by-step release and storage of records about pressure in the cuffs. The used algorithms for calculation of statistical indicators of blood pressure and pulse rate do not require special design. There is a possibility of one-time measuring of blood pressure and real-time remote monitoring by a specialist.

At the current stage there is a prototype of a device, which is being tested to confirm the efficiency and reliability of autonomous work. In future it is planned to conduct the update of the logarithm and device construction with an aim to minimize the dependence of the quality of pressure measuring from the patient’s body position during monitoring.
