The PPG sensor is a special sensor, which uses a photoplethysmography technique to detect physiological parameters of a human body, and comprises at least two sensor components, namely a light receiver and a light emitter. In the related art, in order to detect the accuracy of data, the scheme of using multiple light transmitters and multiple light receivers can meet the requirements of sports, daily scenes and the like, but the power consumption of the whole machine is increased, so that the actual use duration of a user is shortened. Therefore, in order to solve the problems in the related art, embodiments of the present disclosure provide a method for acquiring physiological parameters, which starts a corresponding PPG sensor to acquire physiological parameter data by determining a wearing state of a user, and ensures that an optimal data acquisition scheme is adopted in different usage scenarios, instead of directly adopting a scheme of multiple light emitters and multiple light receivers to acquire physiological data, thereby saving power consumption of the entire device.
As shown in fig. 1, fig. 1 is a flowchart illustrating a method for acquiring a physiological parameter according to an embodiment of the present disclosure, where the method for acquiring a physiological parameter may be performed by a wearable device, and the wearable device may be a bracelet, a watch, or other devices having a heart rate detection function, and in this embodiment, the wearable device is configured with a sensor for acquiring physiological parameter data, and the sensor may be a PPG sensor. The method shown in fig. 1 comprises:
step 101, determining the wearing state of the user.
In one embodiment, the wearing state of the user is a degree of tightness when the user perceives that the wearable device is in contact with the wearing part after the user wears the wearable device. For example, the wearable device is a smart watch worn on the wrist, and the wearing state of the wearable device can be three wearing states of fitting, loosening and tightening when the user perceives that the smart watch is worn on the wrist.
In one embodiment, the wearable device comprises a tightness detection device, and the weighing value of the tightness can be obtained through the tightness detection device; and judging the wearing state of the user according to the magnitude relation between the weighing value of the tightness and a preset threshold value.
The preset tightness threshold may be one or two or more, and in a preferred embodiment, the preset tightness threshold is two, namely, a first threshold and a second threshold. In one embodiment, the first threshold and the second threshold may be empirical values. For example, pressure values of different wearing states of a user wearing the bracelet are obtained through a pressure sensor installed on the smart bracelet, and a first threshold value and a second threshold value are obtained by counting the pressure values obtained from various bracelets or other possible wearable devices. The first threshold value is a reference value when the wearing state of the user is tight, and the second threshold value is a reference value when the wearing state of the user is loose.
When the weighing value of the tightness is not more than the first threshold, the wearing state of the user is judged to be tight, and the quality of the acquired PPG (photoplethysmography) signal is general and even poor; when the weighing value of the tightness is not less than the second threshold, the wearing state of the user is judged to be loose, and the quality of the acquired PPG (photoplethysmography) signal is general and even poor; when the weighing value of the tightness is between the first threshold value and the second threshold value, the wearing state of the user is judged to be proper, and the acquired PPG (photoplethysmography) signal is good in quality. It will be appreciated that the better the PPG signal quality, the more accurate the physiological parameter calculated therefrom.
In one embodiment, the tightness detecting device may be, for example, an ITO coated electrode, and a first measurement value is obtained through the ITO coated electrode, and a measure of the tightness is obtained according to the first measurement value. When the measure of the tightness is not more than the first threshold, the wearing state of the user is tight, the quality of the collected PPG signal is general or even poor, and when the measure of the tightness is not less than the second threshold, the wearing state of the user is loose, the quality of the collected PPG signal is general or even poor; when the measure value of the tightness is between the first threshold value and the second threshold value, the wearing state of the user is proper, and the quality of the acquired PPG signal is good. In this embodiment, an indium tin oxide ITO coated electrode is disposed in a possible area where the wearable device is in contact with the skin, and when the wearing state of the user is different, the contact area between the indium tin oxide ITO coated electrode and the skin is different, the corresponding generated impedance value is also different. And determining the weighing value of the tightness according to the impedance values measured in different wearing states after the user wears the wearable equipment.
In one embodiment, the tightness detection device comprises a pressure sensor and an Indium Tin Oxide (ITO) coating electrode, and before acquiring the measure value of the tightness, a first measurement value is acquired through the ITO coating electrode, and a second measurement value is acquired through the pressure sensor; and then, weighting the first measurement value and the second measurement value to obtain a measure value of the tightness. When the measure of the tightness is not more than the first threshold, the wearing state of the user is tight, the quality of the collected PPG signal is general or even poor, and when the measure of the tightness is not less than the second threshold, the wearing state of the user is loose, the quality of the collected PPG signal is general or even poor; when the measure value of the tightness is between the first threshold value and the second threshold value, the wearing state of the user is proper, and the quality of the acquired PPG signal is good.
In this embodiment, compared with the method that a pressure sensor or an ITO electrode is used alone to determine the wearing state of a user, the ITO electrode is disposed in a possible area where the wearable device is in contact with the skin in the embodiment of the present disclosure, and when the wearing state of the user is different, the contact area between the ITO electrode and the skin is different, and the corresponding generated impedance value is also different. Meanwhile, when the wearing states of the users are different, the pressure values detected by the pressure sensors are also different. Under the actual wearing state of wearable equipment, not only the pressure value that wearable equipment perceived, but also the area of contact of wearable equipment and skin compare the result that obtains in single way, this disclosed embodiment obtains the weighing value of elasticity through combining impedance value and pressure value, can be better in the aspect of data reliability and accuracy.
In a preferred embodiment, the weighting factor of the first measured value and the second measured value can be determined from the actual application by weighting the first measured value and the second measured value. For example, in the actual use process of the wearable device, by obtaining the relationship between the first measurement value and the second measurement value, and the measure of the tightness, under different wearing states of the user, through data statistical analysis, the weighting coefficient of the first measurement value and the second measurement value is obtained.
Step 102, starting a corresponding sensor to acquire physiological parameter data according to the wearing state of a user; wherein the wearable device is configured with a plurality of sensors, each sensor comprising a light receiver and a light emitter, the light receiver and the light emitter being arranged at different locations of the wearable device.
As shown in fig. 2, fig. 2 is a schematic diagram of a distributed structure of a biosensor of a wearable device according to an embodiment of the present disclosure. The biosensor can be a PPG sensor, the wearable device is provided with a plurality of sensor components, each sensor component is a light receiver or a light emitter, and the light receivers and the light emitters are arranged at different positions of the wearable device at intervals. It is understood that the PPG sensor includes a plurality of sensor components, and at least two sensor components may be selected as needed to form the PPG sensor, wherein the sensor components forming the PPG sensor include both the optical receiver and the optical emitter.
In one embodiment, a first (A) is selected from the plurality of light emitters in case that the wearing state of the user is appropriate1) A number of optical transmitters, and a second (B) selected from a plurality of optical receivers1) A number of optical receivers; and starting a sensor consisting of the selected light emitter and the selected light receiver to acquire physiological parameter data.
In this embodiment, when the wearing state of the user is appropriate, the quality of the PPG signal acquired at this time is good. The better the PPG signal quality, the more accurate the physiological parameter calculated therefrom. Thus, a smaller number of emitter and receiver combinations, e.g. A, may be selected for acquiring physiological parameter data1The number of light emitters and the number of light receivers B1 adjacent to the light emitters constitute a PPG sensor for acquiring physiological parameter data.
A plurality of sensor element distribute in wearable equipment's different regions, therefore when detecting that the user wearing state is suitable, pine, when tight, constitute corresponding PPG sensor through the sensor element who starts different regions, carry out the collection of physiological parameter data, can effectively improve PPG sensor's availability factor, also be favorable to reducing PPG sensor's use consumption simultaneously.
In one embodiment, the third (a) is selected from the plurality of light emitters when the wearing state of the user is inappropriate and the wearing state of the user is loose2) A number of optical transmitters, and a fourth (B) selected from the plurality of optical receivers2) A number of light receivers, wherein the third number is not less than the first number and the fourth number is not less than the second number. And starting a sensor consisting of the selected light emitter and the selected light receiver to acquire physiological parameter data.
In this embodiment, when the wearing state of the user is loose, the quality of the collected PPG signal is generally even poor, and therefore, a relatively large number of combinations of light emitter and receiver, for example, a, may be selected for collecting the physiological parameter data2Number of light emitters and B2The quantity of the light receivers adjacent to the light receiver and the quantity of the light receivers not adjacent to the light receiver form a PPG sensor so as to acquire a plurality of data and improve the accuracy of physiological parameter data.
In one embodiment, the fifth (a) is selected from the plurality of light emitters in a case where the wearing state of the user is inappropriate and when the wearing state of the user is tight3) A number of light emitters, and a sixth (B) selected from the plurality of light emitters3) And a plurality of light receivers, wherein the fifth number is not less than the first number, and the sixth number is not less than the second number, and the selected sensor consisting of the light emitter and the light receiver is started to acquire physiological parameter data.
In this embodiment, when the wearing state of the user is tight, the quality of the collected PPG signal is generally even poor, and therefore, a relatively large number of combinations of light emitter and receiver, for example a, may be selected for collecting the physiological parameter data3Number of light emitters and B non-adjacent thereto3The quantity of the light receivers form a PPG sensor to realize physiologyThe acquisition of parameter data improves the availability factor of PPG sensor, also is favorable to reducing the use consumption of PPG sensor simultaneously.
In an embodiment, as shown in fig. 2, a plurality of light receivers and a plurality of light emitters are configured in the wearable device, wherein the light receivers and the light emitters are arranged at different positions of the wearable device at intervals. At least one optical receiver and at least one optical emitter constitute a PPG sensor, that is to say a PPG sensor comprises at least two sensor components, wherein the sensor components constituting the sensor comprise both an optical receiver and an optical emitter. As shown in FIG. 2, each photoreceiver may be the same distance D1 from an adjacent phototransmitter and may be the same distance D2 from a non-adjacent phototransmitter.
It should be noted that in some preferred embodiments, the light receiver may be a photodiode and the light emitter may be a tri-color LED lamp and/or a single color LED lamp.
In a possible implementation manner, corresponding sensors can be started to acquire physiological parameter data according to different wearing states of the user. Physiological parameter data of the user in various wearing states, such as heart rate, blood oxygen, blood pressure and the like, can be detected by starting the corresponding light emitter and light receiver. A large amount of research data show that the measurement of the heart rate of the user requires a certain distance between the optical receiver and the optical transmitter, so when selecting to start the PPG sensor on the wearable device, in order to test the heart rate of the user in each wearing state, the optical receiver and the optical transmitter in the corresponding area position need to be started. When the wearing state of the user is proper, starting a sensor consisting of a first number of light emitters and a second number of light receivers, wherein the distance between the first number of light emitters and the second number of light receivers is short distance, namely starting the combination of the light emitters and the light receivers in the short distance; in the sensor consisting of the third number of light emitters and the fourth number of light receivers, which is started and selected when the wearing state of the user is not proper and the wearing state of the user is loose, the distance between the third number of light emitters and the fourth number of light receivers comprises a long distance and a short distance, namely, the combination of the light emitters and the light receivers which are started at the long distance and the short distance is started; in the sensor composed of the fifth number of phototransmitters and the sixth number of photoreceivers, which is started to be selected when the wearing state of the user is not proper and the wearing state of the user is tight, the distance between the fifth number of phototransmitters and the sixth number of photoreceivers is long, namely, the combination of the phototransmitters and the photoreceivers which are long in distance is started.
For example, when the wearing state of the user is proper, the quality of the collected PPG signal is good, so 1 light emitter and 1 adjacent short-distance light receiver are selected, another light emitter arranged opposite to the selected sensor component and another short-distance light receiver adjacent to the light emitter are selected, and the sensor (a) is composed of 4 sensor components1＝2，B12) to acquire physiological parameters; under the condition that the wearing state of a user is not appropriate and when the wearing state of the user is loose, the quality of the collected PPG signal is generally even poor, therefore, 1 light emitter and at least one short-distance light receiver adjacent to the light emitter and at least one long-distance light receiver not adjacent to the light emitter are selected, another light emitter arranged opposite to the selected sensor component, a short-distance light receiver adjacent to the light emitter and a long-distance light receiver not adjacent to the light emitter are selected, and a sensor (A) is composed of at least 6 sensor components2＝2，B24) to acquire physiological parameters; under the condition that the wearing state of a user is not proper and the wearing state of the user is tight, the quality of the collected PPG signal is generally even poor, therefore, 1 light emitter and at least one long-distance light receiver which is not adjacent to the light emitter are selected, another light emitter which is arranged opposite to the selected sensor component and a long-distance light receiver which is not adjacent to the light emitter are selected, and a sensor (A) is composed of at least 4 sensor components2＝2，B22) to acquire physiological parameters.
In conclusion, the wearing state of the user is judged; starting a corresponding sensor to acquire physiological parameter data according to the wearing state of a user; the wearable device is provided with a plurality of sensors, each sensor comprises a light receiver and a light emitter, and the light receivers and the light emitters are arranged at different positions of the wearable device, so that the optimal data acquisition scheme is adopted in different use scenes, and physiological data are acquired by the scheme of not directly adopting the multi-light emitters and the multi-light receivers, so that the use power consumption of the whole device is saved.
