The patient of peripheral system disorder disease is not easy to use, therefore also it is not recommended that the elderly uses.Above several sphygmomanometers detect speed
Decompression mensuration that is slow, and being all made of is increased rapidly to the gas being slowly discharged in air bag after certain pressure value first,
Pulse wave is obtained in pressure reduction, and blood pressure is calculated by pulse wave.
When inventor applies first technology, find first technology for passing through blood using the method for being depressured measurement blood pressure
After press pump Quick-pressing to fixation pressure value, then slowly decompression, the method pressing speed is fast, increases the tensity of patient,
Comfort level is bad, to influence accuracy of measurement, and measuring speed is slower.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, the present invention provides a kind of blood pressure measurements of dynamic adjustment blood pressure pump
Method, it is fast to solve pressing speed in the prior art, increases the tensity of patient, and comfort level is bad, so that it is quasi- to influence measurement
Exactness, and the technical problem that measuring speed is slower.
A kind of blood pressure measuring method of dynamic adjustment blood pressure pump provided by the invention according to pressurization the following steps are included: refer to
It enables, control blood pressure pump conveys gas to air bag, makes airbag boost air；
In the process of increase in, the pressure value that pressure sensor detects is obtained；
The pressure value is calculated into pressure value by oscillographic method.
Optionally, specifically further include following steps after obtaining pressure value: according to pressure value, calculating accounting for for blood pressure pump
Sky compares variable quantity；
According to the revolving speed of change in duty cycle amount adjustment pump, increase air bag average rate.
Optionally, it according to the revolving speed of change in duty cycle amount adjustment pump, specifically includes: controlling the size of the blood pressure revolution speed
To the change in duty cycle amount to directly proportional.
Optionally, the specific steps that pressure value is calculated by the pressure value that oscillographic method is analyzed include: to
To pressure value be filtered to obtain pulse wave；
The peak point is calculated pressure value for the peak point by oscillographic method by the peak point for identifying the pulse wave
Pressure value is calculated by oscillographic method.
The present invention adjusts the revolving speed of blood pressure pump by dynamic, is at the uniform velocity risen with controlling the pressure value of air bag, be can be realized
Stable measurement blood pressure, improves the accuracy of measurement in pressure process；It is pressurizeed during measuring blood pressure using at the uniform velocity steady,
And suitable pressurization value is pressurized to according to the blood pressure personalization of user, improve the accuracy of measurement.
Detailed description of the invention
It, below will be to embodiment in order to illustrate more clearly of embodiment of the present invention or technical solution in the prior art
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the present invention, for those skilled in the art, without creative efforts, may be used also
To obtain other drawings based on these drawings.
Fig. 1 is a kind of process signal of embodiment of the blood pressure measuring method of dynamic adjustment blood pressure pump provided by the invention
Figure；
Fig. 2 is a kind of stream of the another embodiment of the blood pressure measuring method of dynamic adjustment blood pressure pump provided by the invention
Journey schematic diagram.
Specific embodiment
Below in conjunction with the attached drawing in the application embodiment, the technical solution in the application embodiment is carried out clear
Chu is fully described by, it is clear that described embodiment is only a part of embodiment of the application, rather than whole realities
Apply mode.Based on the embodiment in the application, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, shall fall in the protection scope of this application.
Referring to Fig. 1, Fig. 1 is a kind of embodiment of the blood pressure measuring method of dynamic adjustment blood pressure pump provided by the invention
Flow diagram.
As shown in Figure 1, the blood pressure measuring method of the adjustment blood pressure pump of dynamic described in present embodiment, including following step
It is rapid:
Step S10 is instructed according to pressurization, and control blood pressure pump conveys gas to air bag, makes airbag boost air；
Step S20 obtains the pressure value that pressure sensor detects in the process of increase in；
Step S30, the pressure value analyzed by oscillographic method, calculates pressure value.
Above method is the boosting measurement method used, i.e., pressure value is detected during boosting, this method can
The drawback in decompression measurement method is effectively eliminated, mensuration is such as depressured, is by blood pressure pump Quick-pressing to fixation pressure value
Afterwards, then slowly decompression, the method pressing speed is fast, increases the tensity of patient, and comfort level is bad, so that it is quasi- to influence measurement
Exactness, and measuring speed relatively generally at least could even complete measurement, the liter that the present invention uses at 30 seconds or more slowly more than 1 minute
It presses measurement method quick, measurement can be completed in 20-45 seconds or so, boosting measurement method is substantially than being depressured measurement method speed
Fast 30% or even 40%, whole process is very fast, and comfort level is preferable.
Referring to Fig. 2, Fig. 2 is a kind of the another real of the blood pressure measuring method of dynamic adjustment blood pressure pump provided by the invention
Apply the flow diagram of mode.As shown in Fig. 2, the blood pressure of the dynamic adjustment blood pressure pump in above embodiment is surveyed according to the present invention
Amount method, on this basis, specific further comprising the steps of after obtaining pressure value:
Step S21 calculates the change in duty cycle amount of blood pressure pump according to pressure value；
Step S22 increases air bag average rate according to the revolving speed of change in duty cycle amount adjustment pump.
The duty ratio refers to the ratio of the time that pulse occupies in one section of stream time and total time.
Further, by calculating the variable quantity of the duty ratio of the blood pressure pump signal pin in controller, dynamic is adjusted
The variable quantity of blood pressure revolution speed adjusts the revolving speed of blood pressure pump according to change in duty cycle amount, conveys gas to control blood pressure pump to air bag
The flow of body is pressurized the pressure average rate in air bag, and the change in duty cycle amount is directly proportional to the size of blood pressure revolution speed, when accounting for
When sky is bigger than variable quantity, blood pressure revolution speed is bigger；When change in duty cycle amount is smaller, blood pressure revolution speed is smaller.
The revolving speed for adjusting blood pressure pump in embodiment of the present invention by dynamic, is at the uniform velocity risen with controlling the pressure value of air bag,
It can be realized stable measurement blood pressure in pressure process, improve the accuracy of measurement；Using even during measuring blood pressure
Fast steady pressurization, and suitable pressurization value is pressurized to according to the blood pressure personalization of user, improve the accuracy of measurement.
In the above-described embodiment, it all emphasizes particularly on different fields to the description of each embodiment, without detailed in some embodiment
The part stated may refer to the associated description of other embodiment.The above are adjust blood pressure pump to dynamic provided by the present invention
Blood pressure measuring method description, for those of ordinary skill in the art, the thought of embodiment according to the present invention, specific
There will be changes in embodiment and application range, and to sum up, the contents of this specification are not to be construed as limiting the invention.
