The blood pressure pulse detection data may include a pulse wave generated by the movement of the heart to push blood along the tube, which is a periodic pressure wave. The pulse wave of a human body contains rich physiological information, such as blood pressure, heart rate, cardiovascular information and the like. Through the analysis of the pulse waveform, the cardiovascular health information can be acquired so as to reduce the occurrence of cardiovascular diseases.
During the pressurizing stage of the blood pressure pulse condition detecting device 10, the controller 111 controls the air pump 113 to inflate the air bag 122 through the air pump driving circuit 115, and the air release valve 114 is closed; the controller 111 monitors the pressure of the gas in the gas passage 121 in real time through the pressure sensor 112. When the controller 111 determines that the pressure of the gas is the preset first pressure threshold value, that is, the blood pressure pulse condition detecting device 10 is pressurized to the high pressure value of the human blood pressure, the controller 111 controls the air pump 113 to stop working, that is, the air pump 113 stops inflating the air bag 122. At this time, the pressure of the air bag 122 of the cuff 12 is in a steady state, and the waveform of the pulse wave is not disturbed by the outside, so the controller 112 detects a plurality of pulse waves through the pressure sensor 112, for example, the controller 112 collects 5-15 pulse waves through the pressure sensor 112, and sends the collected pulse waves to the terminal 20 through the interface 110.
As shown in fig. 4, the terminal 20 further establishes communication with the server 30, the terminal 20 transmits the plurality of pulse waves to the server 30, and the server 30 filters the plurality of pulse waves to remove the interference noise. The server 30 obtains the amplitude of each pulse wave, and determines whether the amplitude is within a preset amplitude range; if yes, the server 30 determines the pulse wave with the amplitude within the preset range as the first pulse wave, and filters out the pulse waves except the first pulse wave. The server 30 may obtain the amplitude of the feature point of the first pulse wave, where the feature point may include a reflected wave point, a peak point, a valley point, or other extreme points or inflection points of the first pulse wave.
In other embodiments, the server 30 may further obtain a period of each pulse wave, and filter out pulse waves having periods that are not within a preset period to obtain the first pulse wave, that is, the server 30 uses the period as a filtering condition. Of course, in other embodiments, the amplitude and the period of the pulse wave can be used as the filtering condition.

The server 30 obtains an analysis result from the waveform corresponding to the first pulse wave and transmits the analysis result to the terminal 20 to display the analysis result on the terminal 20. For example, if the server 30 determines that the first pulse wave matches a predetermined smooth pulse waveform, the server 30 determines that the first pulse wave is a smooth pulse; the server 30 further obtains an analysis result from the slippery pulse and transmits the analysis result to the terminal 20.
The server 30 matches the first pulse wave with a preset waveform as described in detail below:
specifically, the server 30 obtains first characteristic information of the first pulse wave and second characteristic information of the preset waveform, respectively, and if a difference between the first characteristic information and the second characteristic information is smaller than a preset difference, the server 30 determines that the first pulse wave is matched with the preset waveform. The characteristic information may include waveform period and waveform stagnation (including extreme point and inflection point) information of the first pulse wave. The waveform stagnation point information includes information such as the number of waveform stagnation points and time intervals between adjacent waveform stagnation points. For example, the difference between the waveform period of the pulse-promoting wave and the waveform periods of other pulse conditions is larger, and if the server 30 determines that the difference between the waveform period of the first pulse wave and the preset waveform period of the pulse-promoting wave is smaller than the preset difference, the server 30 may determine that the first pulse wave is the pulse-promoting wave. If the server 30 determines that the difference is greater than the preset difference, the server 30 determines whether the number of the waveform extreme points of the first pulse wave is 2, wherein the number of the waveform extreme points of the slippery pulse is 2, and determines whether the position of the second waveform stagnation point is lower than the position of the first waveform stagnation point; if yes, the first pulse wave can be judged as the smooth pulse. If the server 30 determines that the number of the waveform extreme points of the first pulse wave is 3, the server 30 further determines whether the interval time between the first waveform stagnation point and the second waveform stagnation point of the first pulse wave is less than a preset time, wherein the preset time is the time interval between the first waveform stagnation point and the second waveform stagnation point of the chordal pulse; if yes, the server 30 determines that the first pulse wave is a string pulse.
The blood pressure pulse condition detection device 10 collects a plurality of pulse waves in the pressurizing stage, so that the collection time of the pulse waves can be shortened, and the detection efficiency of the blood pressure pulse condition detection device 10 is improved; further, the blood pressure pulse condition detecting device 10 collects a plurality of pulse waves when the pressure of the gas is a preset first pressure threshold, the pressure of the air bag 122 of the cuff 12 is in a stable state, the waveform of the pulse waves is not interfered by the outside, and the collection precision of the pulse waves is improved; the server 30 obtains an analysis result according to the waveform corresponding to the first pulse wave, so that the non-medical staff can know the health state of the non-medical staff through the analysis result, and the user experience can be improved.
The present application further provides the blood pressure pulse condition detecting device of the fourth embodiment, wherein the air bag 122 may include reserved air, that is, the air bag 122 still retains the reserved air when the blood pressure pulse condition detecting device 10 completes the decompression phase. Specifically, when the controller 111 controls the deflation valve 114 to deflate the airbag 122, the controller 111 monitors the pressure sensor 112 in real time, and when the controller 111 determines that the pressure of the pressure sensor 112 is the second pressure threshold, the controller 111 controls the deflation valve 114 to stop deflating, so that the airbag 122 retains the reserved gas.
The controller 111 performs pressure detection on the reserved gas through the pressure sensor 112, and judges whether to start blood pressure pulse condition detection according to a pressure detection result; if yes, the blood pressure pulse condition detection device 10 detects the blood pressure pulse condition. Specifically, the controller 111 determines the pressure variation amplitude of the gas within a preset time interval according to the pressure detection result, and when the controller 111 determines that the pressure variation amplitude is greater than a preset variation amplitude threshold, the controller 111 starts the blood pressure pulse condition detection to obtain the blood pressure pulse condition detection data.
In other embodiments, the controller 111 further obtains the pressure detection result and the pressure variation amplitude of the second pressure threshold, and when the controller 111 determines that the pressure variation amplitude is greater than the preset variation amplitude threshold, the controller 111 starts the blood pressure pulse condition detection.

The controller 111 further obtains the pressurization rate of the gas in the airbag 122 based on the static pressure and compares the pressurization rate with a constant rate; when the controller 111 judges that the pressurization rate is less than the constant rate, the controller controls the rotation speed of the air pump 113 to increase; when the controller 111 determines that the acceleration rate is greater than the constant rate, the controller 111 controls the rotation speed of the air pump 113 to decrease so that the pressurization rate is the constant rate. Therefore, the controller 111 controls the air pump 113 to inflate the airbag 122, and further controls the air pump 113 to inflate at a constant speed through the air passage 121, so as to ensure the accuracy of the pulse wave obtained by the controller 111.
