Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a mobile terminal human body continuous blood pressure monitoring device and method:
example one
As shown in figure 1, the human body continuous blood pressure monitoring device at the mobile terminal is used for being installed on the mobile terminal. The mobile-end human continuous blood pressure monitoring device comprises a data acquisition module, a data judgment module, a data analysis module and a data storage module.
The data acquisition module is used for reading the blood pressure data acquired by the continuous blood pressure sensor in real time after the mobile terminal is successfully matched and connected with the continuous blood pressure sensor.
In some embodiments, the mobile terminal and the continuous blood pressure sensor are paired through bluetooth, for example, the mobile terminal and the continuous blood pressure sensor are paired and connected based on bluetooth low energy 4.0, and currently, both an Android mobile phone and an iPhone mobile phone support the bluetooth, so that the use is very convenient.
Generally, the mobile terminal is a mobile device such as a smart phone. Because the smart phone has various platforms (such as Android, iOS and the like), a Qt development library can be adopted to complete cross-platform operation, and the purpose that software codes of Android, iOS and windows platforms can be edited and compiled for multiple times to generate mobile phone software is achieved.
The data judgment module is used for judging whether the blood pressure data read by the data acquisition module is valid data. For example, if the received blood pressure data is a random piece of data or the amplitude difference between the received blood pressure data and the baseline is smaller than the set threshold, the blood pressure data is considered to be invalid data, and the subsequent processing is not performed on the blood pressure data (e.g., the calculation of the systolic pressure and the diastolic pressure is not performed on the blood pressure data).
In some embodiments, the method for determining whether the blood pressure data is valid data is as follows: and setting a data sliding window, arranging the received blood pressure data into data lines (each blood pressure data is taken as a data point) according to the receiving time, sliding the data sliding window along the data lines, and judging whether the blood pressure data in the data sliding window is valid data or not. The step length of each sliding of the data sliding window contains less data points than the whole data sliding window, so that omission of data points is avoided in the sliding process of the data sliding window along the data line.
The data analysis module is used for extracting the data characteristics of the blood pressure data judged as effective data by the data judgment module and obtaining the systolic pressure, the diastolic pressure and the heart rate according to the data characteristics. Typically, the data features include one or more of maxima, minima, peaks and peaks in the original signal waveform formed by the blood pressure data, and a frequency spectrum.
In some embodiments, the data analysis module performs preprocessing on the blood pressure data before performing data feature extraction on the blood pressure data, where the preprocessing includes smoothing the blood pressure data, removing waveform burrs, reducing noise interference, and the like.
The data storage module is used for storing the systolic pressure, the diastolic pressure and the heart rate which are obtained by the data analysis module so as to carry out trend detection on the blood pressure of the human body for a long time.
In some embodiments, the mobile terminal human continuous blood pressure monitoring device further includes a waveform generation module, and the waveform generation module is configured to generate an original signal waveform according to the blood pressure data acquired by the data acquisition module, and display the original signal waveform to a user.
For example, the data acquisition module acquires original blood pressure data by reading the data of bluetooth at a speed of every 50 milliseconds, the waveform generation module generates an original signal waveform according to the blood pressure data, because the systolic pressure and the diastolic pressure in clinic correspond to the maximum value and the minimum value in the original signal waveform, in order to ensure the accuracy of continuous measurement, the data of 1 second is analyzed in the analysis to acquire the clinical blood pressure data, the acquired original waveform is shown in fig. 2, the abscissa of fig. 2 represents the specific time of continuous detection, and the ordinate represents the amplitude of the human blood pressure.
Example two
As shown in fig. 3, a method for monitoring continuous blood pressure of a mobile terminal is applied to the device for monitoring continuous blood pressure of a mobile terminal in the first embodiment. The method for monitoring the continuous blood pressure of the human body at the mobile terminal comprises the following steps:
s1, the mobile terminal and the continuous blood pressure sensor are connected in a matched mode.

And S13, selecting continuous blood pressure sensors needing to be paired from the displayed target equipment which can be paired currently for pairing connection.
And S2, reading the blood pressure data collected by the continuous blood pressure sensor after the pairing connection is successful.
In some embodiments, after reading the blood pressure data collected by the continuous blood pressure sensor, a raw signal waveform is generated according to the blood pressure data, and the raw signal waveform is displayed to the user. The maxima and minima in the raw signal waveform correspond to the systolic and diastolic blood pressure in the clinic.
And S3, judging whether the blood pressure data is valid data.
For example, if the received blood pressure data is a random piece of data or the amplitude difference between the received blood pressure data and the baseline is smaller than the set threshold, the blood pressure data is considered to be invalid data, and the subsequent processing is not performed on the blood pressure data (e.g., the calculation of the systolic pressure and the diastolic pressure is not performed on the blood pressure data).
In some embodiments, the method for determining whether the blood pressure data is valid data is as follows: setting a data sliding window; sliding the data sliding window along a data line formed by blood pressure data, and judging whether the blood pressure data in the data sliding window is valid data; the data line formed by the blood pressure data is a data line formed by the blood pressure data according to the receiving time sequence, and each blood pressure data is a data point in the data line. And when the data sliding window is positioned at the initial position, the data sliding window protects the data point representing the first read blood pressure data. The step length of each sliding of the data sliding window contains less data points than the whole data sliding window, so that omission of data points is avoided in the sliding process of the data sliding window along the data line.
And S4, if the blood pressure data is valid data, extracting the data characteristics of the blood pressure data.
Typically, the data features include one or more of maxima, minima, peaks and peaks in the original signal waveform formed by the blood pressure data, and a frequency spectrum.
In some embodiments, before extracting the data feature of the blood pressure data, the step of preprocessing the blood pressure data is further included, and the preprocessing the blood pressure data includes smoothing the blood pressure data, removing waveform burrs, reducing noise interference and the like.
