Basic body function indicators of the human body include heart rate and respiratory rate. Wherein the heart rate is both reflective of the health of the heart of the person and is also useful for assessing the condition of the cardiovascular system. Pulse waves are formed by periodic pulsations of the heart that propagate outward along arterial blood vessels and blood flow, and thus the contractions of the heart can be inferred from the pulse waves. The pulse wave can represent the pathological and physiological information of human body, and is happy to hurt heart and slow to pulse, and is angry to hurt liver and urgent to pulse, and is surprised to pulse.

Fig. 1 is a flow chart illustrating a method for monitoring index data according to an embodiment of the disclosure. As shown in fig. 1, the method for monitoring index data may include:
s1: and acquiring a pulse wave signal of the target object by using a wearable pulse wave sensor worn by the target object.
The target subject is made to wear the wearable pulse wave sensor before the index data of the target subject (e.g., target person) needs to be monitored.
When index data of a target object is required to be monitored, pulse wave signals of the target object are acquired through the wearable pulse wave sensor.
S2: based on the pulse wave information, heart rate information of the target subject is determined. The heart rate information may include information and RR interval values, among others.
S3: and determining the breathing information of the target object based on the deformation information of the elastic restraint belt, which is worn by the target object and caused by the mechanical movement of the chest cavity, of the target object in the breathing process by using the elastic restraint belt.
When the target person breathes, the elastic restraint belt worn by the target person can accurately identify and capture deformation information of the elastic restraint belt caused by mechanical movement of the chest cavity of the target object in the breathing process. The deformation information may characterize the respiration characteristics of the target object. The respiratory information of the target object can be obtained by utilizing the element connected with the deformation information of the elastic restraint belt, acquiring the deformation information through the element and processing the deformation information through the controller.
S4: and sending the pulse wave signal, the heart rate information and the breathing information to the user terminal so that the user terminal can determine the pulse information, the breathing wave waveform and the breathing frequency of the target object based on the pulse wave signal, the heart rate information and the breathing signal, and displaying the pulse information, the breathing wave waveform, the breathing frequency and the heart rate information of the target object through the user terminal.
The user terminal may be a mobile terminal, a desktop or a server. An application program for processing the pulse wave signal, the heart rate information and the respiration information can be arranged in the user terminal, and the pulse wave signal, the heart rate information and the respiration signal are processed through the application program to obtain pulse information (such as pulse rate or pulse wave), respiration wave waveform and respiration frequency of a target object. The pulse wave, respiratory wave waveform, respiratory rate and heart rate information of the target subject can also be applied to help monitor the health status of the target subject.
The user terminal can be provided with an application program developed based on an android system, the user needs to register for the first time, and the user registration information can be synchronized to a background server. And the account number and the password can be registered for login after the registration is completed. After the user terminal and the Bluetooth equipment are connected, data are acquired from the pulse and respiratory equipment in real time, pulse waves and respiratory wave waveforms are displayed on an interface of the user terminal, pulse information, respiratory frequency values, heart rate variability waveforms and the like are calculated and displayed, and the data and corresponding time are stored.
In this embodiment, a wearable pulse wave sensor worn by a target object is used to obtain a pulse wave signal of the target object, heart rate information of the target object is determined according to the pulse wave signal, and an elastic restraint belt worn by the target object is used to determine respiratory information of the target object based on deformation information of the elastic restraint belt caused by mechanical movement of a chest cavity of the target object in a respiratory process, so that the pulse wave signal, heart rate information and respiratory signal are sent to a preset terminal, and therefore index data of the target object can be accurately monitored, and a user terminal can be helped to rapidly and accurately monitor health states of the target object.
In one embodiment of the present disclosure, step S1 may include: pulse wave signals are acquired based on photoplethysmography (photoplethysmographic, PPG) using a wearable pulse wave sensor. The photoelectric volume pulse wave tracing method is based on an LED light source and a detector, measures attenuated light reflected and absorbed by blood vessels and tissues of a human body, records the pulse state of the blood vessels and measures pulse waves, and is an infrared nondestructive detection technology.
The detection part can be at the finger end or the earlobe, the sensing part is arranged on the inner wall of the detection clamp, the light emitting module and the light receiving module are positioned on the same side, and the detection part is clamped by the clamp when detection is carried out.
Fig. 2 is a schematic diagram of acquiring pulse wave signals in one example of the present disclosure. As shown in fig. 2, the process of acquiring the pulse wave signal of the target object may include: the method comprises the steps of sending a driving signal to an LED light source, irradiating a target object by the LED light source, collecting the target object through a photoelectric sensor to generate an electric signal, carrying out AD conversion on the electric signal, and storing the digital signal by using a memory. In this example, green light of 527nm wavelength, which can obtain a pulse signal with a large amplitude, is selected as the light source for the detection light. The controller sends a driving signal to the LED light source, and the LED light source irradiates the skin of the target object after receiving the driving signal. When the light emitted by the LED light source is incident on the surface of the skin biological tissue of the target object, the continuous diastole and continuous systole of the heart of the target object can cause the blood volume in the blood vessel to generate the pulsatile change along with the continuous diastole and continuous systole, so that the absorption amount of the light in the blood also shows the periodic change. When the heart of the target object contracts, the blood volume in the peripheral vascular bed of the human body increases, the absorption amount of the blood to the light also increases, and the detected light intensity becomes smaller; at diastole of the target subject, the absorption of light by the blood decreases and the detected intensity of light increases. The photosensor converts the detected change in the light intensity signal into an electrical signal, and then AD-converts the electrical signal to a digital signal that characterizes the pulse characteristics of the target object, and stores the digital signal in a memory, so that step S2 can read the digital signal from the memory and process the digital signal.
In the present embodiment, the pulse wave signal of the target person can be acquired quickly, accurately and nondestructively by utilizing photoplethysmography.
In one embodiment of the present disclosure, step S2 may include: and carrying out preprocessing such as abnormal interval detection and trending and peak searching algorithm on the pulse wave signals to obtain the heart rate and heart rate variability (HEART RATE Variability, HRV) of the target person.
Fig. 3 is a schematic diagram of a pulse wave in one example of the present disclosure. As shown in FIG. 3, the abscissa characterizes time information in seconds; the ordinate represents the pulse wave intensity in picoamps. The heart rate and HRV of the target person can be obtained by carrying out preprocessing such as abnormal interval detection, trending and the like on the pulse wave signals and a peak searching algorithm. Where HRV is the variation in the interval time between each heart beat.

In one embodiment of the present disclosure, before step S2, it may include: acquiring the light intensity of a light source (such as a green light source in the above embodiments) used for photoplethysmography; if the light intensity of the light source is larger than the preset maximum threshold value of the illumination intensity, the light intensity of the light source is reduced; if the light intensity of the light source is smaller than the preset minimum threshold value of the illumination intensity, the light intensity of the light source is improved.
In this embodiment, the accuracy of acquiring the pulse wave signal in photoplethysmography can be improved by reading the light intensity of the light source used in photoplethysmography, comparing the light intensity of the light source with a preset maximum threshold value of illumination intensity and a preset minimum threshold value of illumination intensity, and adjusting the light intensity of the light source according to the comparison result.

S3-1: and acquiring the cross-sectional area S of the deformation of the dielectric layer of the elastic restraint belt caused by the mechanical movement of the chest cavity and the distance value d in the preset direction of the target object in the breathing process.
In the respiration process of the target object, the contents of the oxygen-carrying hemoglobin and the reduction hemoglobin in the blood of the target object change, and the absorption coefficient of the blood to light changes accordingly, so that the pulse wave obtained by PPG sampling also contains respiration-related information, and the respiration envelope can be solved from the pulse wave by using a related algorithm, but the method has certain limitation and is easy to be interfered by noise. A flexible constraining tape comprising a semiconducting polymer and nanomaterial can deform during mechanical movement of the chest cavity during human breathing, wherein the capacitive strain sensor changes the cross-sectional area S and the relative distance d of the dielectric layer when elastically deformed.
S3-2: the capacitance change value is determined based on the cross-sectional area S of the deformation of the dielectric layer and the distance value d in a preset direction by using a capacitance strain sensor of an elastic restraint band. Wherein the capacitance change value characterizes the respiration information. The capacitance change value is calculated by the following formula: c=epsilon (S/d), where epsilon is a constant.
In this embodiment, when the target person breathes, the target person breathes to cause deformation of the body, and further cause the cross-sectional area of the dielectric layer of the elastic constraining band to change with respect to the distance value in the preset direction, so that the capacitance value representing the breathing characteristic of the target person can be obtained according to the cross-sectional area of the dielectric layer and the distance value in the preset direction, so that the capacitance value representing the breathing characteristic of the target object can be sent to the user terminal in the subsequent step.

After the index data of the target object is monitored, the first Bluetooth communication unit receives the pulse wave signal of the target object sent by the wearable pulse wave sensor and heart rate information (heart rate information is processed by the first controller according to the pulse wave signal) sent by the first controller, and the received pulse wave signal and heart rate information are sent to an application program (APP) on the user terminal in a Bluetooth communication mode.
