Example 1
Fig. 1 is a flowchart of a pulse wave data collection method according to an embodiment of the present invention. The embodiment of the invention provides a pulse wave data acquisition method, specifically referring to fig. 1, the pulse wave data acquisition method comprises the following steps S101-S109.
S101, setting a plurality of air pressure sampling points in a preset air pressure sampling range.
In specific implementation, a preset air pressure sampling range is divided to obtain a plurality of air pressure sampling points, wherein the air pressure sampling points refer to time points for collecting data of a user, and when the air pressure sampling points are located, the monitoring device works to obtain pulse wave data of the user. Dividing a plurality of air pressure sampling points so as to obtain pulse wave data of a user for further processing for the monitoring device to work.
In one embodiment, the step S101 specifically includes: and setting a plurality of air pressure sampling points in the air pressure sampling range according to the same air pressure interval.
In a specific implementation, the preset air pressure sampling range is uniformly and equally divided, so that more accurate sampling data can be obtained.
S102, selecting an air pressure sampling point from a plurality of air pressure sampling points as a target sampling point according to the sequence from small to large.
In specific implementation, after the sphygmomanometer is started, the air pressure of the pressurizing device is increased at a constant speed, based on the divided air pressure sampling points, the air pressure sampling point is selected from the air pressure sampling points from small to large to serve as a target sampling point, and the currently selected target sampling point is further processed.
S103, adjusting the air pressure of the pressurizing device to the target sampling point.
In a specific implementation, after the air pressure value of the pressurizing device is determined to be adjusted to the air pressure value of the target sampling point, the air pressure in the pressurizing device is stopped from being increased.
S104, acquiring pulse wave signals of the arm of the user at the target sampling point.
In specific implementation, a pulse wave signal of the arm of the user at the target sampling point is acquired through a monitoring device. After dividing a plurality of target sampling points, acquiring pulse wave signals of the arm of the user at the target sampling points, wherein the accuracy of the pulse wave signals can be determined by the number of more divided target sampling points, and the number of divided target sampling points can be specifically set according to an actual scene, for example, in an embodiment, 100 target sampling points are divided, and then 100 pulse wave signals of the arm of the user are finally acquired.
S105, judging whether pulse wave signals of the arm of the user at the target sampling point contain interference signals or not.
In a specific implementation, based on the pulse wave signal of the arm of the user at the target sampling point, whether an interference signal is included is judged, wherein the interference signal comprises body shake, heart beating acceleration caused by emotional agitation and the like. The pulse wave signal can be detected according to a preset algorithm to judge whether the pulse wave signal contains an interference signal or not, or an inductor is arranged, a user is monitored through the inductor, and when the inductor monitors the movement and the shaking of the user, the output signal is the interference signal.
In one embodiment, the step S105 specifically includes: and detecting whether pulse wave signals of the arms of the user at the target sampling point contain interference signals or not according to a preset interference detection algorithm.
In a specific implementation, according to a preset interference detection algorithm, pulse wave signals of the arm of the user at the target sampling point are detected, the current state of the user can be detected, for example, heart beating acceleration of the user caused by emotion agitation when the pulse wave signals of the arm of the user at the target sampling point are obtained, and then the user heart rate is too fast can be calculated through the preset interference detection algorithm, wherein the pulse wave signals of the arm of the user at the target sampling point comprise interference signals.
In an embodiment, the interference detection algorithm comprises: system air leakage algorithm: when the pressure of the expected pulse sampling point is reached, the pump valve is in a closed state, the pressure trend is not changed in theory (except for pulse), but a certain air leakage exists in a general system, the air leakage degree can be calculated according to the change of the pressure trend line, the measurement is carried out within an acceptable range, and otherwise, the error prompt is carried out when a certain threshold value is reached. Anti-motion algorithm: the pulse is generated by pumping blood of the heart, and the systolic phase, diastolic phase, and beat-to-beat intervals of the human heart are all strictly within a certain range, and are also in different cases for different people. The pulse is taken as the expression form of heart pumping blood and has the characteristic of irregular law, and the rising period, the falling period, the pulse interval and the amplitude of the pulse are all strictly limited in a certain range. The anti-motion algorithm is realized based on the method, and the rising period, the falling period, the interval and the amplitude are calculated by continuously identifying the fluctuation of the pressure, the fluctuation which does not accord with the pulse characteristics of the human body belongs to interference, and although different motion models have different parameter characteristics, the probability of accord with the pulse characteristics is very low, and the motion models accord with the pulse characteristics can be completely ignored. Pulse abnormality recognition: when measuring blood pressure, a patient is usually required to rest for a period of time, but often the waiting time is insufficient, and the heart activity is still in the process of gradually recovering to calm in the measuring process, and in addition, the heart activity changes caused by mood swings in the measuring process, and the like, which cause the pulse characteristics to change. A plurality of pulses can be continuously monitored on the pressure step, and the variation of the pulse characteristics can be identified by comparing the differences. It should be noted that the system air leakage algorithm, the anti-motion algorithm and the pulse fluctuation recognition listed in the above-mentioned interference detection algorithm are merely examples, and the specific interference detection algorithm process may be determined by referring to the existing data, so the present invention is not limited in detail.
In an embodiment, referring to fig. 2, after the above step S105, step S110 is further included: if the pulse wave signal of the arm of the user at the target sampling point contains an interference signal, the air pressure of the pressurizing device is kept at the target sampling point, and after a preset time interval, the process goes to step S104.
In a specific implementation, if the pulse wave signal of the arm of the user at the target sampling point includes an interference signal, the air pressure of the pressurizing device is continuously maintained at the target sampling point, that is, the air pressure in the pressurizing device is kept unchanged, the step S104 is skipped after waiting for a preset time, and the specific preset time may be set according to an actual scene, for example, the step S104 is skipped after waiting for 3S. And the measurement is carried out after waiting for the preset time, so that the influence of interference signals can be avoided, the accuracy of acquiring pulse wave signals is improved, and the time can be flexibly set according to actual scenes.
And S106, if the pulse wave signal of the arm of the user at the target sampling point does not contain an interference signal, taking the pulse wave signal of the arm of the user at the target sampling point as sampling data of the target sampling point, and storing the sampling data of the target sampling point.
In specific implementation, whether the interference signal is contained is further judged for the target sampling point, if the interference signal is contained, the pulse wave signal of the current air pressure is obtained after waiting for the preset time, the pulse wave signal of the interference signal under the current air pressure can be effectively eliminated, and the fact that the pulse wave signal obtained by the target sampling point, namely the current air pressure, does not contain the interference signal is ensured. Thus, the sampled data stored at the target sampling point are all free of interference signals.
S107, judging whether all the air pressure sampling points finish sampling.
In specific implementation, it is determined whether the air pressure sampling point is selected from the plurality of air pressure sampling points from small to large to the maximum air pressure sampling point.
S108, if the air pressure sampling points do not finish sampling, selecting the next air pressure sampling point of the target sampling points as a new target sampling point according to the sequence from small to large, and turning to the step of adjusting the air pressure of the pressurizing device to the target sampling point and acquiring pulse wave signals of the arm of the user at the target sampling point.
In a specific implementation, if the maximum air pressure sampling point is not selected, that is, pulse wave data of the user of all divided air pressure sampling points is not acquired, the next air pressure sampling point currently selected as the target sampling point is further needed to be used as a new target sampling point, and the step S103 is skipped. The divided air pressure sampling points are ensured to collect pulse wave data of the user, so that the blood pressure of the user is measured more accurately.
And S109, if all the sampling points finish sampling, taking the sampling data of all the target sampling points as pulse wave data of the user.
In the implementation, if all the sampling points finish sampling, that is, it is judged that the air pressure sampling point is selected from the air pressure sampling points from small to large to the largest air pressure sampling point, the blood pressure of the user can be measured according to the collected pulse wave data of all the users, and the blood pressure measurement is finished.
In one embodiment, the step S109 specifically includes: and if all the sampling points finish sampling, controlling the pressure release valve to be conducted.
In the specific implementation, if all sampling points finish sampling, namely data acquisition is finished, the pressurizing device does not need to pressurize the arm of a user, and the pressure release valve can be controlled to be conducted to release the air pressure in the pressurizing device so as to finish blood pressure measurement.
Dividing the pulse wave data into a plurality of air pressure sampling points, judging whether an interference signal is received or not when the air pressure sampling points are reached, if the interference signal is received, continuing to measure after waiting for a preset time interval, wherein the air pressure is not increased in the waiting process until the interference signal is not received, and storing the pulse wave data of a user corresponding to the current air pressure, thereby eliminating the pulse wave data containing the interference signal, but the air pressure boosting process corresponding to all the acquired pulse wave data is still linearly increased, finally obtaining the blood pressure result of the user by calculating according to an oscillography method, and realizing the effect that the pulse wave data of the user is not influenced by interference factors such as body shaking of the user in the process of acquiring the pulse wave data of the user.

And secondly, sorting pulse wave data corresponding to each pressure point according to the size of the pressure point to form an envelope trend line of pulse amplitude changing along with the pressure. And fitting the discrete curves by adopting a preset fitting algorithm to form a smoother envelope trend line, wherein the fitting principle of the fitting algorithm can be specifically determined by referring to the existing data, and the invention is not particularly limited.
