Method for monitoring changes in pulse wave propagation change rate using the portable sensory modules, working within the system of dispersed wireless network of a body area

摘要

the subject of the invention is a way of monitoring changes in the pulse wave propagation speed pwv using portable sensory modules, operating in the distributed wireless network area wban body.during the initiation module (1) sends the current state of its wireless real-time clock module peripheral (2) during a transmission (3) shorter than the period of sampling signals by a peripheral module (2), in order to achieve synchronization of clocks is not worse than the time trwani a single sample, and a peripheral module (2) positioned on the basis of a real time clock,then after synchronization modules shall accede to the data collection and the module (1) monitor ecg and detects the appearance of it r and remembers state clock at the time of his appearance.then from the detection module (1) r was awaiting the emergence of face wave pulse on the ear person monitored and precisely determines the moment the face that wave and remembers the clock at that moment, in turn a peripheral module (2) monitors the pulse wave on the limb person b adanej (wave distal) awaiting the appearance with this waveand when the calculated moment of his appearance of memorizing condition, real-time clock,then the information of arrival wave pulse along with the clock at this time is sent to the transmission (3) to the module a (1), and after receiving the information from the peripheral module (2) module (1) shall be calculated on the basis of an overriding memorised the clock at the time of it r and state of the clock in time arrival wave pulse proksymalnego obtained from peripheral module (2), andstate of the clock with the pulse wave propagation time dystalnego, ptt (pulse ptt heart - heart - hand and ear, ptt ptt ear - hand), then dividing the distance between locations of sensors adopted by the calculated time propagation ptt ear - hand stays in the module (1) yliczona current pulse wave propagation speed pwv.
