Referring to fig. 1, the present application provides a blood pressure detecting system 101 according to an embodiment, where the blood pressure detecting system 101 includes a blood pressure detecting device 102, a terminal 104, and a server 105. The blood pressure detecting device 102 may be worn on the left arm or the right arm of the user.
The terminal 104 establishes communication connections with the blood pressure detection apparatus 102 and the server 105, respectively. Wherein, the terminal 104 can establish a wired connection or a wireless connection with the blood pressure detecting device 102, and the terminal 104 can establish a wireless connection with the server 105.
The terminal 104 of the present embodiment 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 105 may be an intelligent computer system distributed in a network or a cloud.
The present application provides an information sharing method of an embodiment, which is applied to a blood pressure detection system 101, as shown in fig. 2, and the information sharing method specifically includes the following steps:
s201: blood pressure test data and treatment plans of a plurality of users are obtained.
The server 105 may establish communication with a plurality of blood pressure detection devices 102, one blood pressure detection device 102 may be worn by each user; in other embodiments, each user may wear multiple blood pressure detection devices 102. The server 105 controls the plurality of blood pressure detection devices 102 to respectively detect the blood pressure detection data of the corresponding users, and receives the blood pressure detection data of the plurality of users through the terminal 104, so that the server 105 acquires the blood pressure detection data of the plurality of users; the blood pressure detection data may include blood pressure, brain waves, or blood oxygen saturation, etc.
Wherein the user can record the treatment plan on the terminal 104, the server 105 can obtain the treatment plan of the user from the terminal 104.
S202: and respectively generating a blood pressure curve of each user along with the change of time according to the blood pressure detection data.
The server 105 respectively generates a blood pressure curve of each user along with the change of time according to the blood pressure detection data; that is, the server 105 may establish a coordinate system, with time as the abscissa of the coordinate system, and blood pressure detection data as the ordinate of the coordinate system; the server 105 generates a blood pressure curve varying with time on a coordinate system from the blood pressure detection data of each user to form a plurality of blood pressure curves. The server 105 further monitors the blood pressure detection data of the user in real time, and can remind the user when the blood pressure detection data is abnormal. Wherein the blood pressure curves may include blood pressure curves without a treatment regimen and blood pressure curves with a treatment regimen applied.
S203: the treatment protocol was labeled on the blood pressure curve.
The server 105 marks the treatment plan on the blood pressure curve according to the time of the treatment plan. For example, the treatment plan may include the name and amount of the drug, which the server 105 marks on the blood pressure curve according to the time of administration.
Wherein the server 105 marks the treatment plan on the blood pressure curve on which the treatment plan is applied. Specifically, the server 105 may determine a time point at which the user applies the treatment plan, and intercept a partial blood pressure curve of a predetermined period of time subsequent to the time point from the blood pressure curve at which the treatment plan is not applied; the server 105 correlates the truncated partial blood pressure curve with the blood pressure curve for applying the treatment plan to allow the user to display the blood pressure curve for applying the treatment plan and the partial blood pressure curve simultaneously. That is, the terminal 104 is used for the user to simultaneously display the blood pressure curve and the partial blood pressure curve for applying the treatment plan, and the user can know the effect of the treatment plan through the blood pressure curve and the partial blood pressure curve for applying the treatment plan.
S204: and receiving a transmission instruction of the user, and transmitting the marked blood pressure curve to other user terminals.
The server 105 receives the transmission instruction of the user and transmits the marked blood pressure curve to other user terminals. That is, the user inputs a transmission instruction through the terminal 104, and the server 105 receives the transmission instruction of the user from the terminal 104 and transmits the marked blood pressure curve to other user terminals according to the transmission instruction. For example, the server 105 obtains the marked blood pressure curve of the user a, and receives a sharing instruction (i.e., a transmission instruction) of the user a; the server 105 may send the marked blood pressure curve of the user a to the terminal 104 of the user B according to the sharing instruction, so that the user B obtains the marked blood pressure curve of the user a through the terminal 104.
The embodiment shares the marked blood pressure curve among the users, that is, the users can share the marked blood pressure curve to other users for reference of other users, thereby promoting communication among the users and improving activity of the users.
In one embodiment, step S201 further includes: the server 105 obtains individual characteristics of the user, the individual characteristics including at least one or a combination of age, height, weight, and body fat rate. The terminal 104 may store the individual characteristics of the user in advance, and the server 105 acquires the individual characteristics of the user from the terminal 105; alternatively, the server 105 stores the individual characteristics of all users in advance, and further obtains the individual characteristics of the users.
In step S203, the server 105 marks an individual characteristic, for example, the individual characteristic is a weight, on the blood pressure curve to which the treatment plan is applied, and the server 105 marks the weight of the user and the treatment plan together on the blood pressure curve to which the treatment plan is applied, so as to improve accuracy.
In other embodiments, the main execution body of the present application may be the terminal 104, which is not described herein again.
The present application provides an information sharing method according to another embodiment, as shown in fig. 3, the information sharing method includes the following steps:
s301: blood pressure test data and treatment plans of a plurality of users are obtained.
S302: and respectively generating a blood pressure curve of each user along with the change of time according to the blood pressure detection data.
Steps S301 to S302 are the same as steps S201 to S202, and are not described again here.
S303: the blood pressure curves of different users without treatment protocols are similarity matched.
The server 105 similarity matches the blood pressure curves of different users without treatment. For example, the server 105 may select at least one blood pressure curve from a plurality of blood pressure curves without the treatment plan as a template curve, and construct a discretized first index; the server 105 constructs a second index at the same time point according to the blood pressure curve to be matched to which the treatment plan is not applied, and calculates a similarity according to a first index and a second index, which may be any one of blood pressure, brain wave, and blood oxygen saturation, to perform similarity matching on the blood pressure curves of different users.
Alternatively, the server 105 may perform similarity matching on blood pressure curves without treatment application, for which the difference between the individual features is smaller than a preset difference threshold. For example, if the individual characteristic is a weight, the preset difference threshold may be 5kg, the weight of the first user is 75kg, the weight of the second user is 73kg, and the weight of the third user is 60kg, the server 105 performs similarity matching between the blood pressure curve of the first user without the therapy and the blood pressure curve of the second user without the therapy.
S304: and recommending friends among users with the similarity larger than a preset similarity threshold.
The server 105 carries out friend making recommendation among users with the similarity larger than a preset similarity threshold; specifically, the server 105 recommends the same chat group to users whose similarity is greater than the similarity threshold; that is, the server 105 may preset a plurality of chat groups, and recommend the same chat group to users with a similarity greater than a similarity threshold (the similarity threshold may be 80%), so that users with a similarity greater than the similarity threshold join the same chat group through the terminal 104.
Or the server 105 recommends friends among users with the similarity greater than the similarity threshold, and the users with the similarity greater than the similarity threshold can make friends with other users with the similarity greater than the similarity threshold.
Through the mode, the user can communicate with and share other users, such as a blood pressure curve applying a treatment scheme or the treatment scheme, so that a friend making function is realized, and the activity of the user is improved; in addition, friend making recommendation is carried out among users with the similarity greater than a preset similarity threshold, and the precision of friend making can be improved.
S305: the treatment protocol was labeled on the blood pressure curve.
S306: and receiving a transmission instruction of the user, and transmitting the marked blood pressure curve to other user terminals.
Steps S305-S306 are the same as steps S203-S204 and will not be described herein.
How the server 105 acquires the health information of the human body is described in detail below.
Since the human health information is often obtained by using rich empirical data and inference rules, the server 105 can acquire rich blood pressure detection data and has strong data processing capability, so that the server 105 can analyze the blood pressure detection data to acquire the human health information, and accuracy of blood pressure detection and data processing can be improved. In addition, the terminal 104 of the embodiment displays the health information and the blood pressure detection data, so that the user can know the health condition of the user in time, and the risk of diseases is reduced.
Specifically, the server 105 may pre-store blood pressure detection data, which may include a normal blood pressure detection data range, a plurality of blood pressure detection data of the same human body, a plurality of blood pressure detection data of human bodies, and the like. The server 105 may also pre-store other physiological data and mapping relationship between the other physiological data and the blood pressure detection data. The server 105 may analyze the blood pressure detection data forwarded by the terminal 104 according to the pre-stored blood pressure detection data to obtain the health information of the human body. For example, the server 105 may compare the blood pressure detection data of the human body a transferred by the terminal 104 with the normal blood pressure detection data range, or compare the blood pressure detection data of the human body a transferred by the terminal 104 with the past blood pressure detection data of the human body a, or compare the blood pressure detection data of the human body a transferred by the terminal 104 with the blood pressure detection data of the human body B, and obtain the health information of the human body a according to the comparison result.
The blood pressure detection data may include a pulse wave generated by the heart pulse pushing blood along the blood vessel, 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.
Alternatively, in order to improve the accuracy of the health information, the server 105 needs to perform filtering processing on the plurality of pulse waves after acquiring the plurality of pulse waves from the terminal 104 to remove the interference noise.
Specifically, the server 105 acquires the amplitude of the pulse wave, and determines whether the amplitude is within a preset amplitude range; if yes, the server 105 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. Further, the server 105 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 point or inflection point of the first pulse wave.
Of course, in another embodiment, the server may further obtain a period of the pulse wave, and filter 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. 4, 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 105 of the embodiment further performs pulse condition (waveform) recognition on the first pulse wave.
Specifically, the server 105 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 105 matches the first pulse wave with a preset waveform after filtering the plurality of pulse waves forwarded by the terminal 104; the server 105 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 105 determines that the first pulse wave forwarded by the terminal 104 matches a preset smooth pulse waveform, it determines that the first pulse wave is a smooth pulse; the server 105 may further transmit the first pulse wave or the first preset waveform and the health information "slippery pulse" back to the terminal 104.
Optionally, the server 105 obtains first feature information of the first pulse wave and second feature information of the preset waveform, respectively, and if a difference between the first feature information and the second feature information is smaller than a preset difference, the server 105 determines that the first pulse wave matches the preset waveform.
Specifically, the feature information of the present embodiment may include the waveform period and the waveform stagnation point (including the extreme point and the 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. 4, the difference between the waveform period of the pulse-promoting waveform and the waveform periods of other pulse conditions is large, and if the server 105 determines that the difference between the waveform period of the first pulse wave and the preset waveform period of the pulse-promoting waveform is smaller than the preset difference, the first pulse wave can be determined as the pulse-promoting. If the server 105 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 first waveform stagnation point; if yes, the third pulse wave can be determined as the smooth pulse. If the server 105 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 (the time interval between the first waveform stagnation point and the second waveform stagnation point of the preset chordal pulse); if yes, the first pulse wave can be judged as a string pulse.
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 105 may filter the acquired waveform stagnation points before performing pulse recognition to reduce noise interference.
Pulse diagnosis is one of the four diagnostic methods in diagnostics of traditional Chinese medicine, 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 the pulse wave, so that a user can visually know the pulse condition through the pulse wave, health information is obtained from the pulse condition, 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 waveform.
To solve the above problem, the server 105 of this embodiment further analyzes the first pulse wave to obtain more specific human health information from the first pulse wave, and 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 105 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 105 may also obtain pulse rate, AI value, and the like from the first pulse wave.
The server 105 returns the acquired health information to the terminal 104, and the terminal 104 displays the health information, as shown in fig. 5 and 6.
Further, the server 105 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 104 to be normal; if not, the health information display state on the terminal 104 is abnormal.
The server 105 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 104, and the terminal 104 displays the pulse waveform, the type, and the blood pressure data.
Optionally, the server 105 of this embodiment further obtains health information of the elasticity of the blood vessel of the human body according to the reflected wave point and the peak point, for example, if the server 105 determines that the reflected wave point is on the right side of the peak point (as shown in fig. 5), the obtained health information is that the elasticity of the blood vessel is better; if the server 105 determines that the reflected wave point is on the left side of the peak point (as shown in fig. 6), the acquired health information is that the elasticity of the blood vessel is poor.
The server 105 can also acquire health information such as bradycardia or tachycardia and arrhythmia according to the heart rate data; the server 105 may also obtain arterial health information from the AI values. The terminal 104 may also display such health information.
