The present application firstly proposes a blood pressure pulse condition detecting system, as shown in fig. 1, a blood pressure pulse condition detecting system 101 of this embodiment includes a blood pressure pulse condition detecting device 102, a terminal 103 and a server 104, the terminal 103 establishes communication connection with the blood pressure pulse condition detecting device 102 and the server 104 respectively, the blood pressure pulse condition detecting device 102 is used for detecting blood pressure pulse condition detection data of a human body, the terminal 103 is used for receiving the blood pressure pulse condition detection data from the blood pressure pulse condition detecting device 102, the terminal 103 forwards the blood pressure pulse condition detection data to the server 104, the server 104 analyzes the blood pressure pulse condition detection data and obtains human body health information according to an analysis result, the server 104 returns the health information to the terminal 103, and the terminal 103 displays the health information.
The terminal 103 may include a mobile phone, a tablet computer, a notebook computer, a palm top computer, a personal digital assistant, a wearable device, and the like, and the server 104 is an intelligent computer system distributed in a network or a cloud.
The terminal 103 of this embodiment may establish a connection or a wireless connection with the blood pressure pulse condition detection device 102, and the terminal 103 may establish a wireless connection with the server 104.
The server 104 of this embodiment analyzes the blood pressure pulse detection data forwarded by the terminal 103 to obtain the health information of the human body, and the terminal 103 can display the health information returned by the server 104 and the blood pressure pulse detection data detected by the blood pressure pulse detection device 102.
Since the human health information is usually obtained by abundant empirical data and inference rules, the server 104 can obtain abundant blood pressure pulse condition detection data and has strong data processing capability, so that the blood pressure pulse condition detection data is analyzed by the server 104 to obtain the human health information, and the accuracy of blood pressure pulse condition detection and data processing can be improved. In addition, the terminal 103 of the embodiment displays the health information and the blood pressure and pulse condition detection data, so that the user can know the self health condition in time and reduce the risk of diseases.
Specifically, the server 104 may pre-store the blood pressure pulse condition detection data, which may include a normal blood pressure pulse condition detection data range, a plurality of blood pressure pulse condition detection data of the same human body, a plurality of blood pressure pulse condition detection data of human bodies, and the like. The server 104 may also pre-store other physiological data and mapping relationship between the other physiological data and the blood pressure pulse condition detection data. The server 104 can analyze the blood pressure pulse detection data forwarded by the terminal 103 according to the pre-stored blood pressure pulse detection data to obtain the health information of the human body. For example, the server 104 may compare the blood pressure pulse condition detection data of the human body a forwarded by the terminal 103 with the normal blood pressure pulse condition detection data range, or compare the blood pressure pulse condition detection data of the human body a forwarded by the terminal 103 with the past blood pressure pulse condition detection data of the human body a, or compare the blood pressure pulse condition detection data of the human body a forwarded by the terminal 103 with the blood pressure pulse condition detection data of the human body B, and the like, to obtain the health information of the human body a according to the comparison result.
The blood pressure pulse condition detection data comprises pulse waves, wherein the pulse waves are generated by pushing blood to move along a tube by the heart and are periodic pressure waves. 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.
Alternatively, in order to improve the accuracy of the health information, the server 104 needs to perform filtering processing on the plurality of pulse waves after acquiring the plurality of pulse waves from the terminal 103 to remove the interference noise.
Specifically, the server 104 obtains the amplitude of the pulse wave, and determines whether the amplitude is within a preset amplitude range, if so, the server 104 determines that the pulse wave with the amplitude within the preset range is the first pulse wave, and filters out the pulse waves except the first pulse wave. Further, the server 104 may obtain the amplitude of the feature point of the first pulse wave, which may include a reflected wave point, a peak point, a valley point, or other extreme or inflection point of the first pulse wave.
Certainly, in another embodiment, the server may further obtain a period of the pulse wave, and filter out the pulse wave whose period is not within a preset period to obtain the first pulse wave, that is, the period is used as the filtering condition. Of course, in other embodiments, the amplitude and the period of the pulse wave can be used as the filtering condition.
Different human bodies or the same human body in different health states generate different pulse waves, i.e. different pulse conditions. The pulse conditions of traditional Chinese medicine are various, such as the smooth pulse, the pulse-promoting pulse, the chordal pulse, the Pingtai pulse, the superficial pulse, the deep pulse, the slow pulse, the rapid pulse, the deficient pulse, etc., and the waveforms of each pulse condition are different, as shown in fig. 2, and the waveforms of the smooth pulse, the pulse-promoting pulse, the chordal pulse and the Pingtai pulse are all different.
Different pulse conditions represent different health conditions of the human body, and in order to improve the accuracy of the health information, the server 104 of the embodiment further performs pulse condition (waveform) recognition on the first pulse wave.
Specifically, the server 104 of the present embodiment stores preset waveforms, which at least include a smooth pulse waveform, a pulse promoting waveform, a chordal pulse waveform, a flat pulse waveform, or the like. The server 104 matches the first pulse wave with a preset waveform after filtering the plurality of pulse waves forwarded by the terminal 103; the server 104 further obtains a preset waveform matched with the first pulse wave as a first preset waveform, and obtains health information according to the first preset waveform. For example, if the server 104 determines that the first pulse wave forwarded by the terminal 103 matches a preset smooth pulse waveform, it determines that the first pulse wave is a smooth pulse; the server 104 may further transmit the first pulse wave or the first predetermined waveform and the health information "slippery pulse" back to the terminal 104.
Optionally, the server 104 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 104 determines that the first pulse wave is matched with the preset waveform.
Specifically, the characteristic information of the present embodiment may include a waveform period and a waveform stagnation point (including an extreme point and an 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. As shown in fig. 2, the difference between the waveform period of the pulse-promoting wave and the waveform periods of other pulse conditions is large, and if the server 104 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 first pulse wave can be determined as the pulse-promoting wave; if the server 104 determines that the difference is greater than the preset difference, it further determines whether the number of waveform extreme points of the third pulse wave is 2 (the number of waveform extreme points of the preset smooth pulse is 2), and determines whether the amplitude of the second waveform stagnation point is larger and lower than the position of the first waveform stagnation point, if so, it may determine that the third pulse wave is a smooth pulse; if the server 104 determines that the number of the waveform extreme points of the third pulse wave is equal to 3, it may further determine whether the interval time between the first waveform stagnation point and the second waveform stagnation point of the third pulse wave is less than a preset time (a time interval between the first waveform stagnation point and the second waveform stagnation point of the preset chordal pulse), if so, it may determine that the first pulse wave is a chordal pulse, and so on.
The pulse condition (waveform) of the pulse wave can be identified through the waveform period and the waveform stagnation point information of the pulse wave. Of course, in other embodiments, the pulse condition (waveform) of the pulse wave can be identified according to other characteristic information of the pulse wave.
Of course, the server may filter the acquired waveform stagnation point before performing pulse recognition to reduce noise interference.
The pulse diagnosis is one of the four diagnostic methods in TCM diagnostics, and is a unique diagnostic method. It mainly uses the finger sense to analyze the pulse 'position, number, shape and potential' characteristics to judge the functional state of viscera, thus realizing the purpose of non-invasive diagnosis and having positive significance for the diagnosis and treatment of diseases.
Although the existing pulse condition instrument can achieve the process of feeling pulse and graphically display pulse waves, so that a user can visually know the pulse conditions through the pulse waves, the health information is obtained from the pulse conditions, and abundant clinical experience is needed, so that non-medical personnel or non-professional medical personnel are difficult to accurately obtain the health information from the pulse condition waveforms.
To solve the above problem, the server 104 of this embodiment further analyzes the first pulse wave to obtain more specific human health information from the first pulse wave, where the health information of this embodiment includes information such as blood pressure, pulse strength, pulse rate, and reflected wave enhancement index (AI) reflecting elasticity of artery in addition to the pulse condition information.
Specifically, the server 104 obtains several pulse waves with the largest pulse wave amplitude in the whole measurement process, for example, 3 pulse waves, and obtains the pulse strength of the human body according to the average value of the amplitudes of the peak points. The larger the amplitude of the mean value is, the larger the pulse strength is, and the magnitude of the pulse strength represents the strength of the human physique; the server 104 may also obtain pulse rate, AI value, and the like from the first pulse wave.
The server 104 transmits the acquired health information back to the terminal 102, and the terminal 102 displays the health information as shown in fig. 3 and 4.
Further, the server 104 stores a preset range, and determines whether the health information is in the preset range; if yes, controlling the health information display state on the terminal 103 to be normal; if not, the health information display state on the terminal display 103 is abnormal.
The server 104 may also transmit the first pulse wave or the pulse waveform corresponding to the first pulse wave, the type of the first pulse wave, the blood pressure data, etc. back to the terminal 103, and the terminal 103 displays the pulse waveform, the type, and the blood pressure data.
Optionally, the server 104 of this embodiment further obtains health information of the blood vessel elasticity of the human body according to the reflected wave point and the peak point, for example, if the server 104 determines that the reflected wave point is on the right side of the peak point (as shown in fig. 3), the obtained health information is good blood vessel elasticity, and if the server 104 determines that the reflected wave point is on the left side of the peak point (as shown in fig. 4), the obtained health information is poor blood vessel elasticity; the server 104 can also acquire health information such as bradycardia or tachycardia, arrhythmia and the like according to the heart rate data; the server 104 may also obtain arterial health information based on the AI values, and so on. The terminal 103 may also display such health information.
Different from the prior art, the server 104 analyzes the blood pressure pulse condition detection data to obtain the health information of the human body, so that the accuracy of blood pressure pulse condition detection and data processing can be improved; in addition, the terminal 103 of the embodiment can display detailed health information, not just pulse waves, so that non-medical personnel can clearly know the health status of the non-medical personnel through the health information.

The air passage 121 may extend to the host 11, and the air passage 121 may be connected to the pressure sensor 112, the air pump 113, and the air release valve 114, respectively. The air pump driving circuit 115 is connected between the air pump 113 and the controller 111 for driving the air pump 113, i.e., the controller 111 drives the air pump 113 through the air pump driving circuit 115 to fill the air bag 122 with air.
