The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the application provides a charging and discharging control method, which can be applied to electronic equipment such as a terminal or a server. As shown in fig. 1, the method includes:
In the process of controlling inflation and deflation by adopting the oscillography, the oscillography detection mode firstly carries out inflation pressurization operation until the inflation pressure reaches the pre-inflation pressure. When the blood pressure is measured through the inflation and deflation control for the first time, the pre-inflation pressure can be 160mmHg, when the blood pressure is not measured for the first time, the pre-inflation pressure can be determined according to the systolic pressure obtained by the previous blood pressure measurement and the target increment, the target increment can be 40mmHg, and if the systolic pressure obtained by the previous time is 160mmHg, the pre-inflation pressure corresponding to the current inflation and deflation control is 200 mmHg. The magnitude of the pre-charging pressure is not limited in the embodiment of the present application, and can be determined by those skilled in the art according to actual needs.
In the inflation process, the acquisition modes of the multiple target pressures can be determined according to target time points in the process of pressurizing the pre-charging pressure, for example, if the pre-charging pressure time is 10s, the pressures corresponding to the 3 rd second, the 5 th second and the 7 th second can be selected as the target pressures; or selecting the corresponding step pressure in the air charging and discharging control process as the target pressure. The type of the target pressure is not limited in the embodiments of the present application, and can be determined by those skilled in the art according to actual needs. In order to facilitate description of the technical solutions described in the embodiments of the present application, the embodiments of the present application use a step pressure as a target pressure.
The number of the corresponding step pressures in the inflation and deflation control process can be set to 6, the number of the step pressures is not limited in the embodiment of the application, and the step pressures can be determined by a person skilled in the art according to actual use requirements. When the number of the set step pressures is 6, the number of the obtained step pressures may be 6, 5, or 3, and the number of the obtained step pressures is not limited in the embodiment of the present application. The pulse wave signals corresponding to 6 step pressures are obtained to improve the accuracy of subsequent judgment results. And after obtaining a plurality of target pressures, obtaining pulse wave signals corresponding to the target pressures.
And 102, evaluating the quality of the corresponding pulse wave signals according to the pulse wave signals corresponding to each target pressure.
Optionally, in an embodiment, as shown in fig. 2, before performing the quality evaluation on the pulse wave signal, a step 104 of determining whether additional pressurization is required after reaching the pre-inflation pressure according to the pulse wave signal corresponding to the target pressure is further included.
Specifically, after determining that the pre-charge pressure is reached, whether additional pressurization is required may be: and detecting the pulse wave signal characteristics corresponding to the corresponding step pressure in the measurement process to obtain characteristic parameters such as the amplitude, the width, the interval time of adjacent pulse waves and the like of the pulse wave signal, and storing the characteristic parameters in association with the corresponding step pressure. When a plurality of sub-pulse wave signals are detected on one step pressure, taking the average value of the amplitudes of two similar sub-pulse wave signals as the amplitude of the pulse wave signal corresponding to the current step pressure; the similar sub-pulse wave signals can be determined by taking two pulse wave signals with the amplitude and width errors within 20 percent as the similar pulse wave signals;
arranging the step pressures and the pulse wave signal characteristic parameters corresponding to the step pressures in sequence to obtain a pulse wave signal sequence, and judging whether the pre-charging pressure is enough or not according to the formed envelope trend; if not, additional pressurization is required.
In the embodiment of the present application, the determination method for determining whether additional pressurization is needed in the current air charge and discharge control process according to the pulse wave signal corresponding to the target pressure may be: when the target pressure is the maximum step pressure, the pulse wave signal amplitude corresponding to the maximum step pressure is higher than the pulse wave signal amplitude corresponding to the expected systolic pressure, and the fact that extra pressurization is needed in the current inflation and deflation control process is represented; or when the step pressure is reduced, the pulse wave signal amplitude corresponding to the step pressure shows a descending trend, and the characteristic that the current inflation and deflation control process needs additional pressurization is shown.
The embodiment of the present application is not limited to the manner of determining the additional pressurization, and those skilled in the art can determine the additional pressurization according to actual needs. The pulse wave signal amplitude corresponding to the expected systolic pressure can be determined according to the maximum pulse wave signal amplitude multiplied by a target coefficient, and the maximum pulse wave signal amplitude can be obtained by directly traversing and inquiring from a stored pulse wave signal sequence or by an interpolation processing method. The target coefficient may be 0.5, and the target coefficient is not limited in the embodiments of the present application, and can be determined by those skilled in the art according to actual use needs.
For example, when the target pressure is the maximum step pressure, and when the amplitude of the pulse wave signal corresponding to the maximum step pressure is greater than the preset amplitude of the pulse wave signal, indicating that additional pressurization is required in the current inflation and deflation control process, the pulse wave signal corresponding to the maximum step pressure is subjected to additional pressurization operation. When the current inflation and deflation control process does not need to be additionally pressurized according to the pulse wave signal corresponding to the maximum step pressure, the current inflation and deflation control process is subjected to pressure release operation, and when the next step pressure is released, the corresponding pulse wave signal can be the pulse wave signal corresponding to the next step pressure or the pulse wave signal corresponding to the next step pressure and the maximum step pressure.
The quality evaluation of the corresponding pulse wave signals can be performed by pre-establishing and storing an association table of the pulse wave signals with different characteristic parameters and the quality evaluation result, and when the pulse wave signals corresponding to the target pressure in the current inflation and deflation control process are obtained, the corresponding quality evaluation result is obtained by traversing the association table according to the characteristic parameters of the pulse wave signals; or determining a corresponding quality evaluation result according to a comparison result of the obtained characteristic parameter of the pulse wave signal and the target parameter value, for example, when the amplitude of the pulse wave signal is larger than the target amplitude value, which indicates that the pulse wave signal may be interfered by the outside, the corresponding quality evaluation result is poor. The quality evaluation method of the pulse wave signal is not limited in the embodiment of the application, and can be determined by a person skilled in the art according to actual use needs.
And 103, executing corresponding additional pressurization operation according to the evaluation result obtained by the quality evaluation.
According to the evaluation result obtained by the quality evaluation, the corresponding additional pressurization operation can be executed in a mode of executing two operations of additional pressurization and no additional pressurization according to different evaluation results, and the additional pressurization value can be preset; it is also possible to perform the pressurizing operation at different additional pressurizing values according to different evaluation results. Taking the evaluation results as "good" and "normal" as examples, when the evaluation result is "good", the pressurization value may be selected to be 30mmHg, and when the evaluation result is "normal", the pressurization value may be selected to be 15mmHg, or the pressurization value may be selected to be 0. The additional pressurization operation mode is not limited in the embodiments of the present application, and can be determined by those skilled in the art according to actual needs.
As an alternative embodiment of the present application, when it is determined that additional pressurization is required, as shown in fig. 2, the method further comprises:
105, carrying out diastolic pressure detection operation on the current blood pressure test process;
And step 108, finishing the air charge and discharge control.
For example, the diastolic pressure detection operation may be performed by sequentially determining whether additional pressurization is required in the current inflation and deflation control process for the pulse wave signals corresponding to each step pressure, performing diastolic pressure detection when additional pressurization is not required, performing deflation operation until the next step pressure is reached when no diastolic pressure is detected, performing additional pressurization determination and evaluation operation for the pulse wave signals corresponding to the next step pressure, performing diastolic pressure detection again when it is determined that additional pressurization is not required, stopping deflation operation until the diastolic pressure is detected, and ending the inflation and deflation control.
As an optional embodiment of the present application, if additional pressurization is required, the quality evaluation of the corresponding pulse wave signal is performed, as shown in fig. 3, and specifically includes:
1031, obtaining the target characteristic parameters of the pulse wave signals.
Illustratively, the target characteristic parameters of the pulse wave signal in the embodiment of the present application may include: the interval time of the pulse wave signals, the amplitude of the pulse wave signals, the width of the pulse wave signals and the number of included sub-pulse wave signals. The category of the target characteristic parameter of the pulse wave signal is not limited in the embodiment of the present application, and can be determined by those skilled in the art according to the actual use requirement.
1032, evaluating the corresponding pulse wave signals according to the target characteristic parameters.
For example, according to the target characteristic parameters, the corresponding pulse wave signals may be evaluated in a manner that an association relationship table between different target characteristic parameters and evaluation results is established in advance, and when the target characteristic parameters of the corresponding pulse signals are detected, the evaluation results of the corresponding pulse wave signals may be obtained according to the association relationship table.
When the corresponding pulse wave signal is a pulse wave signal corresponding to a single step pressure, the corresponding pulse wave signal may be evaluated according to the target characteristic parameter, or according to a set evaluation criterion, so as to obtain a corresponding evaluation result. In the present embodiment, the evaluation methods in the present embodiment are described by taking the evaluation results "BAD", "COMMON", and "GOOD" as examples:
for example, if at least two similar sub-pulse wave signals are not detected within the set time T, the evaluation result of the pulse wave signal corresponding to the step pressure is "BAD", and the set time T may take any time of [6,10] s. The setting time is not limited in the embodiment of the application, and can be determined by a person skilled in the art according to actual use needs;
if at least two similar sub-pulse wave signals are detected within the set time T, the pulse wave signals can be evaluated according to the following formula;
R＝(RA+RW+RT+RN)/4
wherein RA is the ratio of the minimum pulse wave signal amplitude to the maximum pulse wave signal amplitude; RW is the ratio of the maximum pulse wave signal width to the minimum pulse wave signal width; RT is the ratio of the minimum time interval to the maximum time interval of adjacent pulse wave signals, and if there are only two pulse waves, RT is 1; RN is a constant, and for the current step pressure, the total number of pulse wave signals detected from the beginning to the detection of at least two similar pulse wave signals is assumed to be N0, if N0 is greater than 6, the constant RN is 0.4, otherwise, the constant RN is 0.8.
If R is smaller than the target value S1, the evaluation result of the pulse wave signal corresponding to the step pressure is BAD; if R is greater than or equal to the target value S2, the evaluation result of the pulse wave signal corresponding to the step pressure is "GOOD"; otherwise, the evaluation result of the pulse wave signal corresponding to the step pressure is "COMMON". Where S1< S2, the target value S1 may be 0.5, and the target value S2 may be 0.75. The target value is not limited in the embodiments of the present application, and can be determined by those skilled in the art according to actual use requirements.
As an alternative embodiment of the present application, as shown in fig. 4, step 103 includes;
and 1041, obtaining a comprehensive evaluation result according to the evaluation result of the corresponding pulse wave signal.
For example, the comprehensive evaluation result may be obtained by extracting the corresponding evaluation result from a database storing the evaluation result of the pulse wave signal corresponding to each step pressure for which quality evaluation has been performed and the target characteristic parameter of the pulse wave signal, counting the evaluation result corresponding to each step pressure, and using the number of "GOODs" as the evaluation index of the comprehensive evaluation result. For example, taking the number of step pressures as 6 as an example, the overall evaluation result of pulse wave signals including more than 3 "GOODs" may be determined as "GOOD", and the overall evaluation result of pulse wave signals including 3 or less "GOODs" may be determined as "normal";
as an alternative embodiment of the present application, step 1041 includes:
firstly, constructing a pulse wave signal sequence according to the target pressure and the corresponding pulse wave signal; and acquiring the number of adjacent pulse wave signals meeting abnormal conditions in the pulse wave signal sequence.
Exemplarily, taking the target pressure as the step pressure in the process of controlling the air charge and discharge, the abnormal condition is not limited in the embodiment of the present application, and can be determined by a person skilled in the art according to actual needs, where the abnormal condition is that if the pressure difference between two adjacent step pressures is within 15mmHg and the ratio of the pulse wave signal amplitudes is greater than 5 or less than 0.25; or the pressure difference between two adjacent step pressures is within 15mmHg, the width difference of the corresponding pulse wave signals is more than 15 or less than-15, and the number N1 of the pulse wave signals meeting the abnormal condition is obtained.
Secondly, the number of pulse wave signals satisfying the bulge condition in the pulse wave signal sequence is obtained.
For example, the number of the bumps in the pulse wave signal sequence can be corresponding to the magnitude of the step pressureThe pulse wave signal amplitudes are sequentially arranged to obtain the number of the bulges N2.

firstly, a reference blood pressure value and a pre-charging pressure in the current air charging and discharging control process are obtained.

And secondly, executing corresponding additional pressurization operation according to the reference pressure value, the pre-charging pressure in the current air charging and discharging control process and the comprehensive evaluation result.
For example, according to the reference pressure value, the pre-charge pressure and the comprehensive evaluation result, the additional pressurization operation may be performed according to the comprehensive evaluation result and the target range in which the reference pressure value and the pre-charge pressure are located. For example, when the comprehensive evaluation result is "GOOD" and the reference pressure value and the pre-charging pressure value are in a first target range, the reliability of the analysis result of the envelope trend of the pulse wave signal is high, additional pressurization can be directly performed according to the analysis result and the set pressurization value, and the inflation and deflation control is completed; when the comprehensive evaluation result is "COMMON" or "BAD" and the reference pressure value and the pre-charge pressure value are in the second target range, indicating that the current measurement process may be subjected to external disturbance, the pressurization operation with a pressurization value of 0 may be performed according to the analysis result.

In the actual use process, the determination mode of the dynamic blood pressure monitor and the non-dynamic blood pressure monitor can be determined according to the type parameters manually input into the blood pressure monitor, or according to the change condition of the multiple air charge and discharge control results, for example, if the blood pressure value measured by the blood pressure monitor changes within the target fluctuation range within the target duration, the dynamic blood pressure monitor can be determined. When the reference pressure value is in the invalid state, the reference pressure value may be set to "null" or set to "0" to characterize the invalid state.

Wherein, the target pressure increase value DeltaP4 can take any value of [20, 40], and the DeltaP4 in the embodiment of the application takes 30 mmHg; the next step pressure is equal to the current step pressure — pressure change amount DeltaP3, DeltaP3 generally takes any value of [5,15] mmHg.
