TECHNICAL FIELD

[0002] The present application relates to the electronic technical field, in particular to a physiological parameter measurement method, system and related device. BACKGROUND

[0003] With the continuous development of electronic technology, the functions of electronic devices are becoming more and more diversified, and more and more electronic devices have health monitoring functions. Users can use the health monitoring function of the electronic device to measure physiological parameters such as blood pressure, body temperature, heart rate, etc., and real-time understand their own health status.

[0004] The electronic device can include a PPG module, and the electronic device can measure physiological parameters such as blood pressure through the PPG module. However, the measurement result obtained by this measurement method has a large error, which will affect the user's judgment of their own health status. SUMMARY

[0005] The present application provides a physiological parameter measurement method, system and related device, which realizes the monitoring of physiological parameters in a time period, can obtain more accurate measurement values of physiological parameters, and can also obtain the fluctuation trend of physiological parameters in a time period.

[0006] In a first aspect, the present application provides a physiological parameter measurement method applied to a first electronic device, the first electronic device comprising a first photoplethysmography (PPG) module, the method comprising: obtaining a first PPG signal of a first time period based on the first PPG module; determining first estimation data based on the first PPG signal, the first estimation data comprising a plurality of estimated values of a first physiological parameter in the first time period; determining a first measurement value of the first physiological parameter at a first time, the first time belonging to the first time period; determining a first evaluation result based on the first estimation data and the first measurement value, the first evaluation result comprising measurement values of the first physiological parameter at a plurality of times in the first time period.

[0007] It should be noted that the measurement values of the first physiological parameter at a plurality of times in the first time period refer to the values of the first estimation data after being calibrated by the first measurement value. That is, the measurement values of the first physiological parameter are more accurate than the estimated values.

[0008] Photoplethysmography (PPG) is a technology that uses an optical sensor to sense the change of hemoglobin concentration in the blood flowing inside the blood vessels on the surface of the human body, so as to obtain the pulse of the human body. More and more devices are now equipped with PPG modules to collect PPG signals, and then use the PPG signals to analyze physiological parameters such as blood oxygen saturation, heart rate, respiratory rate, blood pressure, blood sugar, muscle oxygen, vascular resistance, and brain oxygen of the user.

[0009] In this way, the first electronic device can monitor the first physiological parameter based on the PPG module, calibrate the data collected by the PPG module based on the first measurement value, obtain a plurality of measurement values of the first physiological parameter in the first time period, and obtain the fluctuation trend of the first physiological parameter in the first time period, so as to facilitate the user to understand the health status of the user in a timely manner.

[0010] In a possible implementation, the first electronic device further includes a first physiological module; and the first measurement value of the first physiological parameter at the first time point is determined by the first physiological module.

[0011] In this way, the first electronic device can measure the first measurement value of the first physiological parameter by the first physiological module possessed by the first electronic device, without the aid of other devices (such as medical devices, etc.), so that the application range of the physiological parameter measurement method is wider and more flexible. Moreover, the measurement is completed by a single electronic device, which is convenient for the user to carry the electronic device and measure in real time.

[0012] In a possible implementation, the first measurement value of the first physiological parameter at the first time point is determined by the first physiological module, specifically including: receiving a first operation of the first user measuring the first physiological parameter; and in response to the first operation, determining the first measurement value of the first physiological parameter at the first time point by the first physiological module.

[0013] In this way, the measurement can be completed in response to the measurement operation of the user, and the first measurement value is determined. The user can control the measurement time of the first measurement value according to the situation of the user.

[0014] In another possible implementation, the first measurement value of the first physiological parameter at the first time point is determined by the first physiological module, specifically including: detecting that the current time is the preset first time point, and determining the first measurement value of the first physiological parameter at the first time point by the first physiological module.

[0015] In this way, the user does not need to manually operate, and the measurement can be completed without the awareness of the user.

[0016] In a possible implementation, the first physiological module includes any one or more of the following: an electrocardiogram module, a second PPG module, a pressure sensor, and an airbag.

[0017] In this way, the first electronic device can measure the first physiological parameter based on the first physiological module.

[0018] In a possible implementation, the method further includes: determining the first measurement value of the first physiological parameter at the first time point, specifically including: receiving a second operation of the first user; and in response to the second operation, determining the first measurement value of the first physiological parameter at the first time point.

[0019] In this way, the first measurement value can be determined based on the input of the user. The input of the user can include the first measurement value, and optionally, the first time point.

[0020] In a possible implementation, the method further includes: determining the first measurement value of the first physiological parameter at the first time point, specifically including: obtaining the first information sent by the second electronic device, the first information including the first measurement value of the first physiological parameter at the first time point.

[0021] In this way, the first measurement value can be obtained through another electronic device (for example, a medical device, another wearable device, or the like).

[0022] In a possible implementation, the method further includes: obtaining the first information sent by the second electronic device, specifically including: sending a first request to the second electronic device, the first request being used to request to obtain one or more measurement values of the first physiological parameter within a first time period; and receiving a first response sent by the second electronic device, the first response including the first measurement value of the first physiological parameter at the first time point.

[0023] In this way, the first measurement value sent by the second electronic device can be obtained by sending the first request.

[0024] In a possible implementation, the method further includes: determining a second measurement value of the first physiological parameter at a second time point, the second time point belonging to the first time period; and determining the first evaluation result based on the first estimation data and the first measurement value, specifically including: determining the first evaluation result based on the first estimation data, the first measurement value, and the second measurement value.

[0025] In this way, the first estimation data can be calibrated based on two (or more than two) measurement values, the accuracy of the calibration can be improved, and a more accurate first evaluation result can be obtained.

[0026] In a possible implementation, the method further includes: outputting the first evaluation result.

[0027] In this way, after determining the first evaluation result, the first evaluation result can be outputted, so that the user can view the first evaluation result and understand the health status in real time.

[0028] In a possible implementation, the outputting of the first evaluation result specifically includes: outputting any one or more of the following: a first waveform graph, a risk level, a first time period, a reference value, a valid measurement number, and a valid measurement time period; the first waveform graph is used to indicate the fluctuation trend of the first physiological parameter in the first time period; the risk level is used to indicate whether the measurement value of the first physiological parameter in the first time period is risky; the reference value is used to indicate the mean value of the first physiological parameter in the first time period; the valid measurement number is used to indicate the valid measurement number of the first PPG module in the first time period; and the valid measurement time period is used to indicate the time period of the valid measurement of the first PPG module in the first time period.

[0029] In this way, by outputting any one or more of the waveform graph, the risk level, the reference value, the valid measurement number, and the like, more detailed information can be provided to the user, so that the user can understand the health status.

[0030] In a possible implementation, the method further includes: receiving and responding to a third operation of the first user to display a second waveform graph, the second waveform graph being used to indicate the fluctuation trend of the first physiological parameter in a second time period, the second time period having the same length as the first time period and being earlier than the first time period.

[0031] In this way, the fluctuation trend and the evaluation result of the first physiological parameter in the past time period can be viewed. Optionally, the comparison result (for example, rising, falling, stable, and the like) of the first physiological parameter in the current time period and the last time period can also be viewed.

[0032] In a possible implementation, the second time period does not overlap with the first time period, or the second time period overlaps with the first time period.

[0033] In this way, the fluctuation trend of the first physiological parameter in different past time periods can be viewed through the user operation.

[0034] In a possible implementation, the end moment of the first time period is the first moment, and the length of the first time period is a preset length.

[0035] In this way, the first time period can be determined based on the first moment of the first measurement value, so as to determine the first evaluation result of the first time period.

[0036] In a possible implementation, the first physiological parameter includes any one or more of the following: blood pressure, heart rate, blood oxygen saturation, respiratory rate, blood glucose, muscle oxygen, vascular resistance, and brain oxygen.

[0037] Therefore, the first electronic device can determine the estimated data of any one or more physiological parameters through the PPG signal, and calibrate the estimated data based on the measured value of the physiological parameter to obtain the evaluation value of the physiological parameter.

[0038] In a possible implementation, the method further includes: receiving a fourth operation of the second user; in response to the fourth operation, obtaining a third measured value of the first physiological parameter of the second user; and displaying the third measured value.

[0039] In this way, the first physiological parameter of the non-native user can be measured by the first electronic device, and the third measured value can be obtained and output. The second user is a non-native user, and the second user is different from the first user. In this case, the first electronic device will store the third measured value separately to avoid confusion with the measured data of the native user (i.e., the first user).

[0040] In a possible implementation, after obtaining the third measured value of the first physiological parameter of the second user, the method further includes: determining that the current user is not the first user based on the third measured value; and marking the third measured value as non-native user measured data.

[0041] In this way, confusion with the measured data of the native user (i.e., the first user) can be avoided.

[0069] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; the "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0070] Hereinafter, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as implying or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features, and in the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" is two or more than two.

[0071] The term "user interface (UI)" in the following embodiments of the present application is a medium interface for interaction and information exchange between an application program or an operating system and a user, which realizes conversion between internal forms of information and forms acceptable by the user. The user interface is source code written in a specific computer language such as Java, extensible markup language (XML), and the like, and the interface source code is parsed, rendered, and finally presented as content recognizable by the user on an electronic device. A commonly used form of the user interface is a graphic user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be a visual interface element such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, Widgets, and the like displayed in the display screen of the electronic device.

[0072] The following introduces the terms related to the present application.

[0073] Blood pressure measurement mode: The blood pressure measurement mode is divided according to the measurement scene, and can include clinic blood pressure measurement, home blood pressure measurement, ambulatory blood pressure measurement, and the like. Among them, the clinic blood pressure measurement and the home blood pressure measurement both belong to single-point blood pressure measurement, which refers to measuring the blood pressure value of a subject at a single time point.

[0074] Clinic blood pressure measurement: The clinic blood pressure measurement refers to measuring the upper arm arterial blood pressure in a clinic or a hospital by a doctor, a nurse or a technician who has been professionally trained using a desktop mercury sphygmomanometer, an automatic or semi-automatic sphygmomanometer or other medical equipment.

[0075] Home blood pressure measurement: The home blood pressure measurement refers to measuring the blood pressure by a subject himself or with the help of a family member in a place other than a medical unit, which can reflect the blood pressure level in a sober daily life state.

[0076] Ambulatory blood pressure measurement: Ambulatory blood pressure measurement refers to the automatic timing measurement of blood pressure values in daily life state by blood pressure measurement equipment such as blood pressure measurement instrument. Ambulatory blood pressure measurement generally includes the following two basic requirements: one is that medical personnel or technicians install and wear ambulatory blood pressure meter for patients according to the procedure; the second is to set the timing measurement, and the measurement interval can be set differently during the day and at night. Ambulatory blood pressure measurement is generally used to measure the blood pressure fluctuation of the subject within a period of time. Since blood pressure has periodical differences and is disturbed by immediate emotions and other factors, single-point blood pressure measurement cannot completely evaluate the blood pressure state of a day. Ambulatory blood pressure measurement can realize timing measurement within a period of time (for example, 24 hours), and more objectively reflects the actual blood pressure level and variation of the subject within a period of time. However, due to the need for professional collection equipment and the assistance of professionals, ambulatory blood pressure measurement cannot be popularized. At the same time, it is limited by factors such as wearing comfort, and is not conducive to realizing longer (more than 24 hours) blood pressure monitoring. It is impossible to obtain the blood pressure change of the subject in a longer period.

[0077] The blood pressure values measured by different blood pressure measurement modes can be different, so there can be some differences in the diagnosis threshold of hypertension when different blood pressure measurement modes are used.

[0078] For example, FIG. 1 shows the diagnosis threshold of hypertension in different blood pressure measurement modes according to an embodiment of the present application.

[0079] As shown in FIG. 1, the user can obtain a single-time blood pressure measurement value through any one or more of health examination, home blood pressure measurement, self-service blood pressure measurement equipment, wearable device measurement, etc. The blood pressure measurement value can include a systolic blood pressure measurement value and a diastolic blood pressure measurement value.

[0080] In the case of using the clinic blood pressure measurement mode, if the systolic blood pressure measurement value is greater than or equal to 140 mmHg, and the diastolic blood pressure measurement value is greater than or equal to 90 mmHg, then the subject can be diagnosed as having hypertension.

[0081] In the case of using the ambulatory blood pressure measurement mode, the subject needs to meet any one of the following conditions to be diagnosed as having hypertension:

[0082] Condition one: the average of the 24-hour systolic blood pressure measurement value is greater than or equal to 130 mmHg, and the average of the diastolic blood pressure measurement value is greater than or equal to 80 mmHg;

[0083] Condition two: the average of the daytime systolic blood pressure measurement value is greater than or equal to 135 mmHg, and the average of the diastolic blood pressure measurement value is greater than or equal to 85 mmHg;

[0084] Condition three: the average of the nighttime systolic blood pressure measurement value is greater than or equal to 120 mmHg, and the average of the diastolic blood pressure measurement value is greater than or equal to 70 mmHg.

[0085] In addition, in the case of using the ambulatory blood pressure measurement mode, the type of hypertension can also be determined according to the measurement results of the subject at different times. For example, if the subject satisfies the above condition two, it can be diagnosed as morning hypertension; if the subject satisfies the above condition three, it can be diagnosed as night hypertension, etc.

[0086] In the case of determining that the subject is hypertensive by using the clinic blood pressure measurement mode, if the ambulatory blood pressure measurement result of the subject does not satisfy any one of the above conditions one to three, the subject can be diagnosed as white-coat hypertension.

[0087] In the case of using the home blood pressure measurement mode, if the systolic blood pressure measurement value is greater than or equal to 135 mmHg, and the diastolic blood pressure measurement value is greater than or equal to 85 mmHg, it can be diagnosed as hypertension.

[0088] In the case of determining that the subject is hypertensive by using the clinic blood pressure measurement mode, if the home blood pressure measurement result of the subject is that the systolic blood pressure measurement value is less than 135 mmHg, and the diastolic blood pressure measurement value is less than 85 mmHg, the subject can be diagnosed as white-coat hypertension.

[0089] In the case of determining that the systolic blood pressure measurement value of the subject is less than 140, and the diastolic blood pressure is less than 90 mmHg by using the clinic blood pressure measurement mode, if the home blood pressure measurement result of the subject is that the systolic blood pressure measurement value is greater than or equal to 135 mmHg, and the diastolic blood pressure measurement value is greater than or equal to 85 mmHg, the subject can be diagnosed as masked hypertension.

[0090] In the case of determining that the systolic blood pressure measurement value of the subject is less than 140, and the diastolic blood pressure is less than 90 mmHg by using the clinic blood pressure measurement mode, if the ambulatory blood pressure measurement result of the subject satisfies any one of the above conditions one to three, the subject can be diagnosed as masked hypertension.

[0091] It can be understood that the embodiment shown in FIG. 1 is only exemplary, and the threshold of hypertension can be different under different blood pressure measurement modes. In the embodiment of the present application, the threshold of hypertension can also be different from the above-mentioned embodiment, which is not limited herein.

[0159] In this way, the estimated values obtained by the PPG module can be calibrated by the measurement value 1 obtained by the physiological module or the measurement device, so as to obtain the measurement values of the physiological parameter 1 at multiple time points in the time period 1.

[0160] The specific process of the physiological parameter measurement method provided in the embodiment of the present application will be described below.

[0161] For example, FIG. 4 shows a flowchart of the physiological parameter measurement method provided in the embodiment of the present application.

[0162] As shown in FIG. 4, the specific process of the physiological parameter measurement method provided in the embodiment of the present application can include the following steps:

[0163] S401. The electronic device 100 determines a PPG signal by the PPG module.

[0164] In some embodiments, the electronic device 100 can start the PPG module after booting and monitor the PPG signal in real time.

[0165] In some other embodiments, the electronic device 100 can start the PPG module after the user enables the monitoring function of the physiological parameter 1 and monitor the PPG signal in real time.

[0166] It should be noted that the photoplethysmography (PPG) is a technology for sensing the change of the concentration of hemoglobin flowing in the blood vessels on the surface of the human body by using an optical sensor, so as to obtain the pulse of the human body. More and more devices are now equipped with PPG modules to collect PPG signals, and then use the PPG signals to analyze the physiological parameters such as blood oxygen saturation, heart rate, respiratory rate, blood pressure, blood sugar, muscle oxygen, vascular resistance, and brain oxygen of the user.

[0167] S402. The electronic device 100 determines a set of estimated values Al of the physiological parameter 1 in the time period 1 based on the PPG signal.

[0168] In embodiments of the present application, the physiological parameter 1 can include, but is not limited to, any one or more of the following: blood oxygen saturation, heart rate, respiratory rate, blood pressure, blood glucose, muscle oxygen, vascular resistance, brain oxygen, and the like.

[0169] The length of the time period 1 can be a preset length, for example, 24 hours, 12 hours, 6 hours, 4 hours, or 2 hours, and the like.

[0170] In some embodiments, the time period 1 can refer to a preset time period. The electronic device 100 can be pre-provided with fixed monitoring time periods, and the length of each monitoring time period can be referred to as a period, and the length of a period can be 24 hours, 12 hours, or 2 hours, and the like. The electronic device 100 can divide different monitoring time periods according to the period, for example, if the length of a period is 6 hours, then one day can be divided into four monitoring time periods, which are 00:00-06:00, 06:00-12:00, 12:00-18:00, and 18:00-24:00, in order from early to late.

[0171] In other embodiments, the time period 1 can refer to a time period with a preset length ending at the current time. The preset length can be the length of a monitoring time period in the above embodiments, i.e., the length of a period. For example, if the current time is 10:08 and the length of a period is 2 hours, then the time period 1 can refer to the time period between 08:08 and 10:08. It should be noted that in this case, the time period 1 can be updated in real time based on the change of the current time.

[0172] In some embodiments, the electronic device 100 can store an evaluation algorithm Fl(·) of the physiological parameter 1, and the input of the evaluation algorithm Fl(·) can be a PPG signal, and the output can be the estimated value of the physiological parameter 1 at multiple time points in the collection time period of the PPG signal. Therefore, after collecting the PPG signal in the time period 1, the electronic device 100 can take the PPG signal in the time period 1 as the input of the evaluation algorithm Fl(·), and obtain a set of estimated values Al of the physiological parameter 1 in the time period 1 through the evaluation algorithm Fl(·).

[0173] In some embodiments, after the electronic device 100 collects the PPG signal of the time period 1, the electronic device 100 can sort the PPG signals of the multiple time points based on the waveform features of the PPG signals of the multiple time points, to obtain the fluctuation trend of the physiological parameter 1 in the time period 1. Then, the electronic device 100 can take the physiological parameter 1 corresponding to the PPG signal of one time point in the time period 1 as a reference value, and obtain the relative values of the physiological parameter 1 of other multiple time points in the time period 1 relative to the physiological parameter 1 of the time point based on the sorting result. The reference value and the relative values can be regarded as a set of estimated values A1 of the physiological parameter 1 in the time period 1.

[0174] The following describes a logic for determining the fluctuation trend of the physiological parameter 1 in the time period 1 based on the PPG signal by the electronic device 100 according to an embodiment of the present application.

[0175] For example, in the time period 1, the following multiple sub-periods are sequentially included in chronological order: the sub-period T1, the sub-period T2, the sub-period T3, and the sub-period T4. In each sub-period, the PPG signal can include one peak point and two valley points, and the waveform of the PPG signal can have one of the valley points as a starting point and the other valley point as an ending point.

[0176] FIGS. 5A-5D respectively show the waveforms of the PPG signals in the sub-period T1 to the sub-period T4 according to an embodiment of the present application.

[0177] As shown in FIG. 5A, in a two-dimensional coordinate system, the horizontal coordinate can represent time, and the vertical coordinate can represent the amplitude of the PPG signal. The curve Q1 can represent the waveform of the PPG signal corresponding to the T1 sub-period. The curve Q1 can include one peak point and two valley points. On the curve Q1, the amplitude of the peak point is K1.

[0178] As shown in FIG. 5B, in a two-dimensional coordinate system, the horizontal coordinate can represent time, and the vertical coordinate can represent the amplitude of the PPG signal. The curve Q2 can represent the waveform of the PPG signal corresponding to the T2 sub-period. The curve Q2 can include one peak point and two valley points. On the curve Q2, the amplitude of the peak point is K2.

[0179] As shown in FIG. 5C, in a two-dimensional coordinate system, the horizontal coordinate can represent time, and the vertical coordinate can represent the amplitude of the PPG signal. The curve Q3 can represent the waveform of the PPG signal corresponding to the T3 sub-period. The curve Q3 can include one peak point and two valley points. On the curve Q3, the amplitude of the peak point is K3.

[0180] As shown in FIG. 5D, in a two-dimensional coordinate system, the horizontal coordinate can represent time, and the vertical coordinate can represent the amplitude of the PPG signal. Curve Q4 can represent the waveform of the PPG signal corresponding to the T4 sub-period. Curve Q4 can include one peak point and two valley points. On curve Q4, the amplitude of the peak point is K4.

[0181] After obtaining the PPG signals of the above-mentioned multiple sub-periods, the electronic device 100 can sort the PPG signals based on the characteristics of the PPG signals. The characteristics of the PPG signals can include, but are not limited to, any one or more of the following: the amplitude of the peak point, the length of the sub-period, the difference between the peak point and the valley point, the derivative of the PPG signal waveform, etc. Among them, taking blood pressure as the physiological parameter 1 as an example, in the case of other characteristics being the same, the higher the amplitude of the peak point, the higher the blood pressure; the shorter the length of the sub-period, the higher the blood pressure; the greater the difference between the peak point and the valley point, the higher the blood pressure, etc.

[0182] For example, in the embodiments shown in FIGS. 5A-5D, the relationship between the lengths of the sub-periods is T3 < T1 < T2 < T4, and the relationship between the amplitudes of the peak points of the PPG signals is K3 > K1 > K2 > K4; if the physiological parameter 1 is blood pressure, the sorting results of the PPG signals corresponding to the above-mentioned four sub-periods can refer to the embodiment shown in FIG. 5E below.

[0183] As shown in FIG. 5E, the sorting results of the PPG signals of the T1 sub-period to the T4 sub-period, from low to high, are the PPG signal of the T4 sub-period shown in (a) of FIG. 5E, the PPG signal of the T2 sub-period shown in (b) of FIG. 5E, the PPG signal of the T1 sub-period shown in (c) of FIG. 5E, and the PPG signal of the T3 sub-period shown in (d) of FIG. 5E. Among them, the waveforms of the PPG signals of the T1 sub-period to the T4 sub-period can refer to the related descriptions in the embodiments shown in FIGS. 5A-5D above, which will not be described here.

[0184] Taking blood pressure as the physiological parameter 1 as an example, after obtaining the sorting results of the PPG signals of the four sub-periods, the electronic device 100 can determine the fluctuation trend of the blood pressure in the time period 1 based on the sorting results, which can refer to the embodiment shown in FIG. 5F below.

[0185] As shown in FIG. 5F, in the two-dimensional coordinate system, the horizontal axis can represent time, and the vertical axis can represent the relative value of blood pressure. The fluctuation trend of blood pressure in time period 1 determined based on the PPG signal can be represented by curve Q5 in the two-dimensional coordinate system. Curve Q5 can include a plurality of points in time sequence, such as point P1, point P2, point P3, and point P4. Point P1 can be the first peak point of curve Q5, and also the point with the maximum amplitude of curve Q5. Point P2 can be the trough point between the two peak points of curve Q5. Point P3 can be the second peak point of curve Q5. Point P4 can be the point corresponding to the end time of time period 1, or the point with the minimum amplitude of curve Q5. Taking point P4 as a reference value, assuming that the blood pressure value corresponding to point P4 is 1, the blood pressure value of point P1 relative to point P4 can be considered as 1.208. Similarly, the blood pressure values of other points relative to point P4 can be determined based on the amplitudes of the other points on curve Q5 relative to the amplitude of point P4.

[0186] In the manner described in the embodiments shown in FIGS. 5A-5F, the estimated values of blood pressure at a plurality of time points in time period 1 relative to the reference blood pressure at a specific time point can be determined based on the PPG signal, and the fluctuation trend of blood pressure in time period 1 can also be determined.

[0187] It can be understood that the embodiments shown in FIGS. 5A-5F are only examples. In the embodiments of the present application, the electronic device 100 can also determine a set of estimated values of other physiological parameters different from blood pressure in time period 1 and the fluctuation trend of the other physiological parameters in time period 1 in the above-described manner, which is not limited in the present application. In addition, the electronic device 100 can also determine a set of estimated values of physiological parameter 1 in time period 1 based on the PPG signal in a manner different from the above-described embodiments, which is not limited in the present application.

[0188] S403. The electronic device 100 determines the measurement value 1 of physiological parameter 1 at time point 1, and time point 1 belongs to time period 1.

[0189] It should be noted that steps S403 and S402 can be executed in parallel (for example, time point 1 is any time point in time period 1), or step S402 can be executed first and then step S403 (for example, time point 1 can be the end time of time period 1), or step S403 can be executed first and then step S402 (for example, time point 1 can be the start time of time period 1), and the specific execution order of steps S402 and S403 is not limited in the present application.

[0190] In some embodiments, the electronic device 100 can perform step S403 when detecting that the measurement condition is satisfied. The measurement condition can include, but is not limited to, any one or more of the following: receiving a user operation of measuring the physiological parameter 1; detecting that a time interval between a last measurement time reaches a preset time length; detecting that a current time is a preset measurement time; receiving a measurement value 1 of the physiological parameter 1 sent by the measurement device 200, and the like.

[0191] In some embodiments, the electronic device 100 can include a physiological module, and the electronic device 100 can measure the measurement value 1 of the physiological parameter 1 at the time 1 through the physiological module. In a possible implementation, the physiological module can include an air bag, and in this case, the electronic device 100 can measure the physiological parameter 1 of the user through the air bag and a pressure sensor and the like. In another possible implementation, the physiological module can include any one or more of the following: an ECG module, a PPG module, a pressure sensor module, and the like, and in this case, the electronic device 100 can determine the physiological parameter 1 of the user based on any one or more of the ECG signal, the PPG signal, and the pressure signal and the like collected by the physiological module. It can be understood that the embodiments herein are only two examples, and in the embodiments of the present application, the physiological module can also include more, less or different devices than the above-described embodiments, which are not limited herein.

[0192] In some other embodiments, the electronic device 100 can also prompt the user to input the measurement value 1 of the physiological parameter 1 when detecting that the measurement condition is satisfied, and optionally, can also prompt the user to input a measurement time of the measurement value 1. The electronic device 100 can determine the measurement value 1 of the physiological parameter 1 based on the input operation of the user, and optionally, can also determine the measurement time (i.e., the time 1) of the measurement value 1 based on the input operation of the user. For example, the interface related to the input of the measurement value 1 of the physiological parameter 1 can refer to the related description in the embodiment shown in FIG. 11B below.

[0193] In some other embodiments, the electronic device 100 can also acquire the measurement value 1 of the physiological parameter 1 through the measurement device 200 when detecting that the measurement condition is satisfied. The specific process in which the electronic device 100 acquires the measurement value 1 of the physiological parameter 1 through the measurement device 200 can refer to the related content in the embodiment shown in FIG. 6 below, which is not described in detail herein.

[0194] In a possible implementation, the time 1 can refer to any one of the time periods 1.

[0195] In another possible implementation, the time instant 1 can also refer to an ending time instant of the time period 1. For example, if the time period 1 is the time period that is updated in real time based on the current time instant in the step S402, in this case, the electronic device 100 can determine the ending time instant of the time period 1 as the time instant 1 when the measurement value 1 of the physiological parameter 1 at the time instant 1 is obtained, and perform the step S404 and the following steps.

[0196] In some other embodiments, the electronic device 100 can also obtain a plurality of measurement values of the physiological parameter 1 within the time period 1, which can include the measurement value 1 at the time instant 1. The plurality of measurement values can also be used to determine the evaluation result 1 of the physiological parameter 1 within the time period 1 in the step S404.

[0197] S404. The electronic device 100 determines an evaluation result 1 of the physiological parameter 1 based on the estimated value A1 and the measurement value 1 of the physiological parameter 1, the evaluation result 1 being used to indicate the measurement values of the physiological parameter 1 at a plurality of time instants within the time period 1.

[0198] In some embodiments, the electronic device 100 can determine an estimated value 1 of the physiological parameter 1 at the time instant 1 based on a set of estimated values A1 of the physiological parameter 1 within the time period 1. Then, the electronic device 100 can determine a calibration model based on the measurement value 1 and the estimated value 1, and determine the measurement values of the physiological parameter 1 at a plurality of time instants within the time period 1 based on the calibration model and the set of estimated values A1.

[0199] For example, if the physiological parameter 1 is blood pressure, and the set of estimated values A1 of the physiological parameter 1 within the time period 1 is the blood pressure value relative to the point P4 in the embodiment shown in FIG. 5F, and the measurement value 1 of the electronic device 100 at the time instant 1 is 120 mmHg, and the time instant 1 is the time instant corresponding to the point P4, the measurement values of the physiological parameter 1 at a plurality of time instants within the time period 1 obtained by the electronic device 100 can refer to the embodiment shown in FIG. 5G.

[0200] As shown in FIG. 5G, in a two-dimensional coordinate system, the horizontal axis can represent time, and the vertical axis can represent the size of blood pressure. The curve Q5 can represent the fluctuation of blood pressure within the time period 1. The specific description of the curve Q5 can refer to the related description in the embodiment shown in FIG. 5F, and the difference between the embodiment shown in FIG. 5F and the embodiment shown in FIG. 5G is that the vertical coordinates of the points on the curve Q5 are different. For example, the vertical coordinate of the point P4 can be 120 mmHg, and based on the proportional relationship between the amplitude of the point P1 and the amplitude of the point P4 in the embodiment shown in FIG. 5F, the vertical coordinate of the point P1 can be 145 mmHg. Similarly, the vertical coordinates of the points on the curve Q5 in the embodiment shown in FIG. 5G, i.e., the blood pressure values at a plurality of time instants within the time period 1, can be determined based on the proportional relationship between the amplitudes of other points on the curve Q5 and the amplitude of the point P4.

[0201] It can be understood that the embodiment shown in FIG. 5G is only described by taking blood pressure as an example, and in the embodiments of the present application, the physiological parameter 1 can also be a physiological parameter different from blood pressure, which is not limited herein.

[0202] In this way, the electronic device 100 can determine the measurement values of the physiological parameter 1 at multiple time points in the time period 1 based on the set of estimated values A1 and the measurement value 1. Then, the electronic device 100 can determine the evaluation result 1 of the physiological parameter 1 in the time period 1 based on the measurement values of the physiological parameter 1 at multiple time points in the time period 1.

[0203] In some embodiments, the evaluation result 1 can further include any one or more of the following: a waveform graph of the physiological parameter 1, a risk level, a current monitoring period, a full-day average value of the physiological parameter 1, a valid measurement number, and a valid measurement period; wherein the waveform graph of the physiological parameter 1 can be used to indicate the fluctuation trend of the physiological parameter 1 in the time period 1; the risk level can be used to indicate whether the measurement value of the physiological parameter 1 in the time period 1 is risky; the valid measurement number is used to indicate the valid measurement number of the PPG module in the time period 1, and the valid measurement period is used to indicate the measurement period in which the PPG module performs valid measurement in the time period 1.

[0204] It should be noted that in the embodiments of the present application, valid measurement refers to that the PPG module successfully collects the PPG signal. In a possible implementation, the PPG module can collect the PPG signal of the user with a fixed time interval (for example, 10 minutes, etc.) as a PPG measurement period. If the PPG signal is successfully collected in the PPG measurement period, the electronic device 100 determines that the measurement in the PPG measurement period is a valid measurement. In some embodiments, the electronic device 100 can also determine that the PPG measurement period is a valid measurement period.

[0205] In addition, the electronic device 100 can also determine the valid measurement period based on the valid measurement period and / or the valid measurement number. In some embodiments, the electronic device 100 can determine whether a preset period is a valid measurement period based on whether the proportion of the sum of the lengths of the valid measurement periods in the preset period to the total length of the preset period reaches a preset proportion (for example, 5%, 10%, or 50%, etc.). In other embodiments, the electronic device 100 can also determine whether a preset period is a valid measurement period based on whether the valid measurement number in the preset period reaches a preset number (for example, the valid measurement number reaches 1 time in 1 hour, or the valid measurement number reaches 3 times in 2 hours, etc.).

[0206] In some embodiments, the evaluation result 1 can also include a fluctuation trend of the physiological parameter 1 in the time period 1. The electronic device 100 can determine the fluctuation trend of the physiological parameter 1 in the time period 1 based on the measured values of the physiological parameter 1 at multiple time points in the time period 1. In other embodiments, after determining the set of estimated values of the physiological parameter 1 in the time period 1, the electronic device 100 can also determine the fluctuation trend of the physiological parameter 1 in the time period 1 based on the set of estimated values. The specific manner can refer to the related description in the embodiments of FIGS. 5A-5F, which will not be described here again.

[0207] In some embodiments, the evaluation result 1 can also include a fluctuation trend of the physiological parameter 1 in the time period 1. The electronic device 100 can determine the fluctuation trend of the physiological parameter 1 in the time period 1 based on the measured values of the physiological parameter 1 at multiple time points in the time period 1. In other embodiments, after determining the set of estimated values of the physiological parameter 1 in the time period 1, the electronic device 100 can also determine the fluctuation trend of the physiological parameter 1 in the time period 1 based on the set of estimated values. The specific manner can refer to the related description in the embodiments of FIGS. 5A-5F, which will not be described here again.

[0208] The content of the evaluation result 1 provided in the embodiments of the present application will be described below by taking the physiological parameter 1 as blood pressure as an example.

[0209] Table 1

[0210] For example, when the physiological parameter 1 is blood pressure, the evaluation result 1 can further include a risk level of hypertension. As shown in Table 1, the risk level of hypertension can include low risk (no obvious risk of hypertension), medium risk (possible risk of hypertension), and high risk (high risk of hypertension). The electronic device 100 can store a corresponding relationship between the risk level of hypertension and the reference range, for example, when the average of the whole-day blood pressure is lower than 120 / 75 mmHg, the risk level of hypertension can be determined as low risk; when the average of the whole-day blood pressure is between 120 / 75 mmHg and 130 / 80 mmHg, the risk level of hypertension can be determined as medium risk; and when the average of the whole-day blood pressure is higher than 130 / 80 mmHg, the risk level of hypertension can be determined as high risk.

[0211] In this way, after determining the plurality of measurement values of blood pressure in the time period 1, the average of the whole-day blood pressure can be determined based on the measurement values, and the risk level of hypertension can be determined based on the relationship between the risk level and the reference range.

[0212] It can be understood that the embodiment shown in Table 1 is only an example, and in the embodiments of the present application, the electronic device 100 can also store more, less or different risk levels of hypertension than the above-mentioned embodiments, and the corresponding relationship between the risk level and the reference range can also be different from the above-mentioned embodiments, which are not limited herein.

[0213] In addition, when the physiological parameter 1 is not blood pressure, the electronic device 100 can also store the risk level corresponding to other physiological parameters and the corresponding relationship between the risk level and the reference range, which are not limited herein.

[0214] Table 2

[0215] For example, when the physiological parameter 1 is blood pressure, the evaluation result 1 can further include the average of the whole-day blood pressure. As shown in Table 2, the average of the whole-day blood pressure can include an absolute value (also referred to as a reference value) and / or a range value. The absolute value of the average of the whole-day blood pressure refers to the average of the whole-day blood pressure; and the range value of the average of the whole-day blood pressure refers to the fluctuation range of the average of the whole-day blood pressure. For example, when the average of the whole-day blood pressure adopts an absolute value, the absolute value can be 120 / 74 mmHg; and when the average of the whole-day blood pressure adopts a range value, the fluctuation range of the average of the whole-day blood pressure is that the systolic pressure is between 115 mmHg and 125 mmHg, and the diastolic pressure is between 70 mmHg and 80 mmHg.

[0216] It can be understood that the embodiment shown in Table 2 is only an example, and in the embodiments of the present application, the average of the whole-day blood pressure is related to the actual measurement value, and the specific value of the average of the whole-day blood pressure is not limited herein. It can be understood that the embodiment shown in Table 2 is only an example, and in the embodiments of the present application, the average of the whole-day blood pressure is related to the actual measurement value, and the specific value of the average of the whole-day blood pressure is not limited herein. It can be understood that the embodiment shown in Table 2 is only an example, and in the embodiments of the present application, the average of the whole-day blood pressure is related to the actual measurement value, and the specific value of the average of the whole-day blood pressure is not limited herein.

[0217] In addition, in the case that the physiological parameter 1 is not blood pressure, the electronic device 100 can also determine the all-day average of other physiological parameters, which can be an absolute value or a range value, and the specific form can refer to the related description in the embodiment shown in Table 2 above, which will not be described here.

[0218] Table 3

[0219] For example, in the case that the physiological parameter 1 is blood pressure, if the user actively measures the blood pressure, the evaluation result 1 can also include the current blood pressure value. As shown in Table 3, the current blood pressure value can include an absolute value and / or a range value. The absolute value of the current blood pressure value refers to the blood pressure measurement value actively measured by the current user, and the range value of the current blood pressure value refers to the blood pressure value range in which the blood pressure measurement value actively measured by the current user is located. For example, when the current blood pressure value adopts the absolute value, the blood pressure at the current time can be 120 / 74 mmHg; when the current blood pressure value adopts the range value, the fluctuation range of the blood pressure at the current time is that the systolic pressure is between 115 mmHg and 125 mmHg, and the diastolic pressure is between 70 mmHg and 80 mmHg.

[0220] It can be understood that the embodiment shown in Table 3 is only an example, and in the embodiments of the present application, the current blood pressure value is related to the actual measurement value, and the specific value of the current blood pressure value is not limited in the present application.

[0221] In addition, in the case that the physiological parameter 1 is not blood pressure, the electronic device 100 can also determine the current measurement value of other physiological parameters, which can be an absolute value or a range value, and the specific form can refer to the related description in the embodiment shown in Table 3 above, which will not be described here.

[0222] Table 4

[0223] For example, in the case that the physiological parameter 1 is blood pressure, the evaluation result 1 can also include the blood pressure fluctuation trend. As shown in Table 4, the fluctuation trend can include rising, flat and falling. The electronic device 100 can store the judgment criteria of different fluctuation trends. For example, if the blood pressure average of the current monitoring period increases by 10 / 5 mmHg or more compared with the blood pressure average of the last monitoring period, it can be determined that the fluctuation trend is rising; if the blood pressure average of the current monitoring period changes within 10 / 5 mmHg compared with the blood pressure average of the last monitoring period, it can be determined that the fluctuation trend is flat; if the blood pressure average of the current monitoring period decreases by 10 / 5 mmHg or more compared with the blood pressure average of the last monitoring period, it can be determined that the fluctuation trend is falling.

[0224] In this way, after determining the multiple measurement values of the blood pressure in the time period 1, the mean value of the blood pressure in the whole day can be determined based on the measurement values, and the fluctuation trend of the blood pressure can be determined based on the judgment criteria of the fluctuation trend.

[0225] It can be understood that the embodiment shown in Table 4 is only an example. In the embodiments of the present application, the electronic device 100 can also store more, less or different fluctuation trends and judgment criteria than the above-mentioned embodiments, and the correspondence between the fluctuation trends and the judgment criteria can also be different from the above-mentioned embodiments, which are not limited herein.

[0226] In addition, in the case where the physiological parameter 1 is not blood pressure, the electronic device 100 can also determine the fluctuation trend and the judgment criteria of other physiological parameters, and the specific form can refer to the related description in the above-mentioned embodiment shown in Table 4, which will not be described here.

[0227] It can be understood that the above-mentioned embodiments shown in Tables 1 to 4 are only a group of examples. In the embodiments of the present application, the physiological parameter 1 can also be a physiological parameter different from blood pressure. In this case, the evaluation result 1 can include more, less or different content than the above-mentioned embodiments, which are not limited herein.

[0228] S405. The electronic device 100 outputs the evaluation result 1.

[0229] When it is detected that the output condition is met, the electronic device 100 can output the evaluation result 1. The output condition can include but is not limited to any one or more of the following: receiving a user operation of viewing the evaluation result of the physiological parameter 1; detecting that the electronic device 100 determines the evaluation result 1 in the time period 1, etc.

[0230] The electronic device 100 can output the evaluation result 1 in any one or more of the following ways: display on the display screen, voice broadcast, vibration, indicator light flashing, etc.

[0231] The evaluation result 1 is used to indicate the measurement values of the physiological parameter 1 at multiple times in the time period 1, and can also be used to indicate the fluctuation trend of the physiological parameter 1 in the time period 1. Optionally, the evaluation result 1 can also be used to indicate whether the physiological parameter 1 is normal in the time period 1. Further optionally, the evaluation result 1 can also be used to indicate the fluctuation of the measurement value of the physiological parameter 1 in the time period 1 relative to the historical measurement value of the physiological parameter 1.

[0232] For example, the interface of the electronic device 100 outputting the evaluation result 1 of the physiological parameter 1 can refer to the related description in the embodiments shown in Figures 7D-7F below, which will not be described here.

[0233] It can be understood that the embodiment shown in FIG. 4 is only an example, and in the embodiments of the present application, the physiological parameter measurement method can also include more, less or different steps from the above-mentioned embodiment shown in FIG. 4, which is not limited herein.

[0234] The specific process that the electronic device 100 acquires the measurement value 1 of the physiological parameter 1 through the measurement device 200 is introduced as follows.

[0235] FIG. 6 shows a flowchart of the process that the electronic device 100 acquires the measurement value 1 of the physiological parameter 1 through the measurement device 200 according to an embodiment of the present application.

[0236] As shown in FIG. 6, the specific process that the electronic device 100 acquires the measurement value 1 of the physiological parameter 1 through the measurement device 200 can include the following steps:

[0237] S601. The electronic device 100 sends a request 1 to the measurement device 200, and the request 1 is used to request the measurement device 200 to send the measurement value 1 of the physiological parameter 1 to the electronic device 100.

[0238] Step S601 is an optional step.

[0239] In some embodiments, the electronic device 100 can send the request 1 to the measurement device 200 when it is detected that the measurement condition is met. The specific content of the measurement condition can be referred to the related description in the above-mentioned embodiment shown in FIG. 4, which is not described herein again.

[0240] S602. The measurement device 200 measures the measurement value 1 of the physiological parameter 1.

[0241] In some embodiments, the measurement device 200 can receive and respond to the request 1 sent by the electronic device 100, measure the measurement value 1 of the physiological parameter 1, and record the measurement time of the measurement value 1 as time 1.

[0242] In another embodiment, the measurement device 200 can periodically measure the measurement value of the physiological parameter 1 at a fixed time interval (for example, 2 hours, or 30 minutes, etc.), and record the measurement time of each measurement value.

[0243] S603. The measurement device 200 sends a response 1 to the electronic device 100, and the response 1 includes the measurement value 1.

[0244] In some embodiments, the response 1 can also include the time 1, which can be the measurement time of the measurement value 1.

[0245] In another embodiment, the time 1 can not be included in the response 1, in which case the electronic device 100 can determine the time when the request 1 is sent or the time when the response 1 is received as the time 1.

[0246] In a possible implementation, the measurement device 200 can receive and respond to the request 1 sent by the electronic device 100, and send a response carrying the measurement value 1 to the electronic device 100.

[0247] In another possible implementation, the measurement device 200 can also send the obtained measurement value 1 to the electronic device 100 after measuring the measurement value 1 of the physiological parameter 1. In this case, the electronic device 100 can also not perform the step S601.

[0248] S604. The electronic device 100 determines the measurement value 1 based on the response 1 sent by the measurement device 200.

[0249] The electronic device 100 can determine the measurement value 1 and the time 1 corresponding to the measurement value 1 based on the response 1, where the time 1 is the measurement time of the measurement value 1.

[0250] It can be understood that the embodiment shown in FIG. 6 is only an example, and in the embodiments of the present application, the electronic device 100 can also acquire the measurement value 1 through the measurement device 200 in a manner different from the above-described embodiment, which is not limited herein.

[0251] The following describes a set of measurement interfaces of physiological parameters 1 provided by the embodiments of the present application.

[0252] In some application scenarios, the electronic device 100 can receive and respond to the operation of the user measuring the physiological parameter 1, measure the physiological parameter 1, and display the evaluation result of the physiological parameter 1 in the time period 1 based on the physiological parameter 1. The evaluation result includes the measurement values of the physiological parameter 1 at multiple times in the time period 1, and can also include the fluctuation trend of the physiological parameter 1 in the time period 1. In this way, the electronic device 100 can determine the measurement values of the physiological parameter 1 at multiple times in the time period 1 and the fluctuation trend based on the measurement value 1 of the physiological parameter 1, so as to facilitate the user to understand the health condition in real time.

[0253] For example, taking the physiological parameter 1 as blood pressure, FIGS. 7A-7F show a set of interface diagrams of blood pressure measurement provided by the embodiments of the present application.

[0254] As shown in FIG. 7A, the electronic device 100 can display a health evaluation interface 700. The health evaluation interface 700 can include one or more health evaluation items, such as a blood pressure item 701, a blood oxygen saturation item, a heart rate item, and the like. Each health evaluation item can be used to trigger the electronic device 100 to acquire the evaluation result of the physiological parameter corresponding to the health evaluation item.

[0255] The electronic device 100 can receive and respond to a click operation of the user on the blood pressure item 701 to display a blood pressure interface 710 as shown in FIG. 7B.

[0256] As shown in FIG. 7B, the blood pressure interface 710 can include a measure blood pressure control 711 and a blood pressure monitoring control 712, and optionally, a friend / family member measure control 713. The measure blood pressure control 711 can be used to trigger the electronic device 100 to measure the blood pressure of the user to obtain a blood pressure measurement value of the user at the current time. The blood pressure monitoring control 712 can be used to trigger the electronic device 100 to start a blood pressure monitoring mode, or to trigger the electronic device 100 to display an evaluation result of the blood pressure monitoring. The friend / family member measure control 713 can be used to trigger the electronic device 100 to measure the blood pressure of the current subject and record the measured blood pressure as a friend / family member blood pressure.

[0257] The electronic device 100 can receive and respond to a click operation of the user on the measure blood pressure control 711 to display a blood pressure measurement result interface 720 as shown in FIG. 7C.

[0258] As shown in FIG. 7C, the blood pressure measurement result interface 720 can include a blood pressure measurement value 721, and optionally, an evaluation result control 723, and further optionally, a measurement time 722. The blood pressure measurement value 721 can include a systolic blood pressure measurement value (e.g., 135 mmHg) and a diastolic blood pressure measurement value (e.g., 85 mmHg), and optionally, a heart rate (e.g., 97 beats per minute). The measurement time 722 can be used to indicate the measurement time of the currently displayed blood pressure measurement value 721, e.g., “just now”. The evaluation result control 723 can be used to trigger the electronic device 100 to display an evaluation result of the blood pressure in a specified time period (e.g., 24 hours, 12 hours, 4 hours, or 2 hours, etc.).

[0259] The electronic device 100 can receive and respond to a click operation of the user on the evaluation result control 723 to display a blood pressure evaluation result interface 730 as shown in FIG. 7D.

[0260] As shown in FIG. 7D, the blood pressure evaluation result interface 730 can include a blood pressure fluctuation graph 731, which can be displayed in a two-dimensional coordinate system, where the horizontal axis of the two-dimensional coordinate system can represent time and the vertical axis can represent blood pressure. The blood pressure fluctuation graph 731 can include two groups of discrete points, one group of discrete points can be used to indicate the systolic blood pressure at multiple time points in a specified time period (e.g., 10:00 to 14:00 as shown in FIG. 7D), and the other group of discrete points can be used to indicate the diastolic blood pressure at multiple time points in the specified time period (e.g., 10:00 to 14:00 as shown in FIG. 7D). The two groups of discrete points can also be used to indicate the fluctuation trend of the blood pressure value over time.

[0261] The electronic device 100 can receive and respond to the user's upswipe operation, as shown in FIG. 7E, to display the risk level 732 and the reference value 733 in the blood pressure evaluation result interface 730. Optionally, the blood pressure evaluation result interface 730 can further include any one or more of the following: the monitoring period 734 and the valid measurement control 735. The risk level 732 can be used to indicate the risk level of the user's hypertension, for example, "high risk" can be used to indicate that the user's risk level of hypertension is high based on the blood pressure monitoring results in the current monitoring period. The reference value 733 can be the average value of the blood pressure in the monitoring period, for example, the systolic pressure is 140 mmHg and the diastolic pressure is 100 mmHg. The monitoring period can be used to indicate the monitoring period corresponding to the current blood pressure evaluation result (including the blood pressure fluctuation graph 731, the risk level 732, the reference value 733, etc.). The valid measurement control 735 can be used to trigger the electronic device 100 to display the number of valid measurements of blood pressure and the valid measurement period in a preset time period (for example, one day, or one monitoring period, etc.).

[0262] In some other embodiments, the electronic device 100 can also display the blood pressure evaluation result interface 740 as shown in FIG. 7F after receiving the user's click operation on the evaluation result control 723 shown in FIG. 7C.

[0263] As shown in FIG. 7F, the blood pressure evaluation result interface 740 can include a blood pressure fluctuation graph 741, which can be displayed in a two-dimensional coordinate system, where the horizontal axis of the two-dimensional coordinate system can represent time and the vertical axis can represent blood pressure. The blood pressure fluctuation graph 741 can include two curves, one of which can be a solid line and the other of which can be a dashed line. The solid line can be used to indicate the systolic pressure at multiple times in a specified time period (for example, 10:00 to 14:00 as shown in FIG. 7F), and the dashed line can be used to indicate the diastolic pressure at multiple times in a specified time period (for example, 10:00 to 14:00 as shown in FIG. 7F). The two curves can also be used to indicate the fluctuation trend of the blood pressure value over time. It can be understood that the blood pressure fluctuation graphs shown in FIG. 7D and FIG. 7F are only two examples, and in embodiments of the present application, the blood pressure fluctuation graph can also be in a different form from the above-mentioned embodiments of FIG. 7D and FIG. 7F, which is not limited in the present application.

[0264] It can be understood that the embodiments shown in FIGS. 7A-7F are only a set of examples, and in embodiments of the present application, the physiological parameter 1 measured by the electronic device 100 can also be other physiological parameters besides blood pressure, and the evaluation result displayed can include more, less or different content from the above-mentioned embodiments, which is not limited in the present application.

[0265] In some application scenarios, the electronic device 100 can output different prompts based on whether the blood pressure evaluation of the current period is completed, when the user opens the blood pressure monitoring function and opens the blood pressure monitoring interface. When the blood pressure evaluation of the current period is completed, the electronic device 100 can output an evaluation completion prompt, which can be used to prompt the user that the blood pressure evaluation of the current period is completed, and can also be used to prompt the user to view the blood pressure evaluation result of the current period. When the blood pressure evaluation of the current period is not completed, the electronic device 100 can output an evaluation incomplete prompt, which can be used to prompt the user that the blood pressure evaluation of the current period is not completed, and can also be used to prompt the user to measure blood pressure to complete the blood pressure evaluation of the current period.

[0266] In this way, the electronic device 100 can output different prompts based on whether the blood pressure evaluation is completed, so as to facilitate the user to select different operations based on the current situation, and facilitate the user to obtain the health status of himself in real time.

[0267] As shown in FIG. 8A, the electronic device 100 can display a blood pressure interface 710, which can include a blood pressure monitoring control 712. Other contents of the blood pressure interface 710 can refer to the related description in the embodiment shown in FIG. 7B described above, which will not be repeated here.

[0268] The electronic device 100 can receive and respond to the user's click operation on the blood pressure monitoring control 712 to display a blood pressure monitoring interface 800 as shown in FIG. 8B.

[0269] As shown in FIG. 8B, the blood pressure monitoring interface 800 can include a blood pressure monitoring switch 802, and optionally, a blood pressure monitoring instruction 801, which can be used to introduce the blood pressure monitoring function and the usage of the function. For example, the blood pressure monitoring instruction 801 can include the text "This application collects and analyzes pulse wave data to assess blood pressure risk. Usage: wear for no less than 4 hours". It can be understood that the text in the blood pressure monitoring instruction 801 is only an example, and in the embodiments of the present application, the blood pressure monitoring instruction 801 can also include different content from the above-mentioned embodiments, or can include different wearing time (such as 24 hours or 2 hours, etc.) from the above-mentioned embodiments, which are not limited herein. The blood pressure monitoring switch 802 can be used to indicate whether the blood pressure monitoring function is turned on. In the embodiment shown in FIG. 8B, the blood pressure monitoring switch 802 is in an on state, indicating that the blood pressure monitoring function is currently turned on. Optionally, in the case where the blood pressure monitoring function is turned on, if the blood pressure assessment of the current period has been completed, the blood pressure monitoring interface 800 can also display an assessment completion prompt 803 and an assessment result control 804. The assessment completion prompt 803 can be used to prompt the user that the blood pressure assessment of the current period has been completed. The assessment result control 804 is used to trigger the electronic device 100 to display the blood pressure assessment result of the current period. It should be noted that a period refers to a preset monitoring period, such as 24 hours, 12 hours, 4 hours or 2 hours, etc.

[0270] In some other embodiments, in the case where the blood pressure monitoring function is turned on, if the blood pressure assessment of the current period has not been completed, the electronic device 100 can display a blood pressure monitoring interface 810 as shown in FIG. 8C.

[0271] As shown in FIG. 8C, the blood pressure monitoring interface 810 can include a blood pressure monitoring switch 812 and a blood pressure monitoring instruction 811, and the specific content of the blood pressure monitoring instruction 811 and the blood pressure monitoring switch 812 can be referred to the related description in the above-mentioned embodiment shown in FIG. 8B, which is not repeated here. In addition, if the blood pressure assessment of the current period has not been completed, the blood pressure monitoring interface 810 can also include an assessment incomplete prompt 813 and a blood pressure measurement control 814. The assessment incomplete prompt 813 can be used to prompt the user that the blood pressure assessment of the current period has not been completed, and can also be used to prompt the user to measure blood pressure to complete the assessment. The blood pressure measurement control 814 can be used to trigger the electronic device 100 to measure blood pressure, obtain the measurement value of blood pressure, and complete the blood pressure assessment of the current period.

[0272] It can be understood that the embodiments shown in FIGS. 8A-8C are only a group of examples, and in the embodiments of the present application, the blood pressure monitoring interface displayed by the electronic device 100 can also include more, less or different content from the above-mentioned embodiments, which are not limited herein.

[0273] In some application scenarios, in the case that the electronic device 100 is worn by a non-native user to measure blood pressure, the electronic device 100 can receive and respond to an operation of measuring blood pressure of a family member or friend, measure blood pressure of a subject, and store the blood pressure of the subject separately without counting into the blood pressure measurement record of the native user. In this way, confusion of the health monitoring result of the native user can be avoided.

[0274] As shown in FIG. 9A, the electronic device 100 can display a blood pressure interface 710 as shown in FIG. 9A, which can include a family member or friend measurement control 713. Other contents of the blood pressure interface 710 can refer to the related description in the embodiment shown in FIG. 7B described above, which will not be repeated here.

[0275] The electronic device 100 can receive and respond to a click operation of the user on the family member or friend measurement control 713 to display a blood pressure measurement result interface 900 as shown in FIG. 9B.

[0276] As shown in FIG. 9B, the blood pressure measurement result interface 900 can include a blood pressure measurement value 901, a measurement time 902, and a diagnosis result 903. The specific functions of the blood pressure measurement value 901 and the measurement time 902 can refer to the related description in the embodiment shown in FIG. 7C described above. The diagnosis result 903 can be used to prompt whether the measured blood pressure value this time is normal. It should be noted that the blood pressure measurement value measured this time will not be used to determine the evaluation result of the blood pressure of the user. In this way, the measurement value of the non-native user can be avoided to affect the evaluation result of the blood pressure monitoring of the native user.

[0277] In other application scenarios, in the case that the electronic device 100 is worn by a non-native user to measure blood pressure, the electronic device 100 can also prompt the user to confirm whether the current subject is the native user when detecting that the blood pressure measurement value this time is significantly different from the past, and determine whether the measurement record this time is recorded as the blood pressure measurement record of the native user based on the selection operation of the user. In this way, confusion of the health monitoring result of the native user can also be avoided.

[0278] As another example, as shown in FIG. 9C, the electronic device 100 can display a blood pressure interface 710 as shown in FIG. 9A, which can include a blood pressure measurement control 711. Other contents of the blood pressure interface 710 can refer to the related description in the embodiment shown in FIG. 7B described above, which will not be repeated here.

[0279] The electronic device 100 can receive and respond to a click operation of the user on the blood pressure measurement control 711, and when detecting that the blood pressure measurement value this time is significantly different from the historical blood pressure measurement value, a prompt interface 910 as shown in FIG. 9D can be displayed, which can include a native user confirmation prompt 911.

[0280] As shown in FIG. 9D, the prompt interface 910 can include a native user confirmation prompt 911 for prompting the user to confirm whether the current subject is a user (i.e., a native user) who usually wears the electronic device 100. For example, the native user confirmation prompt 911 can include the text “It is detected that the current blood pressure measurement value is significantly different from the historical blood pressure measurement value. Is the current subject a native user?” The native user confirmation prompt 911 can also include a yes control 912 and a no control 913. The yes control 912 can be used to confirm that the current subject is a native user, and the no control 913 can be used to confirm that the current subject is not a native user.

[0281] It can be understood that the embodiments shown in FIGS. 9A-9D are only two examples. In the embodiments of the present application, the physiological parameter 1 measured by the user can also be a physiological parameter other than blood pressure, which is not limited herein.

[0282] In other embodiments, the electronic device 100 can also measure other physiological parameters of the subject while measuring the physiological parameter 1 of the subject. The electronic device 100 can also prompt the user to confirm whether the current subject is a native user when it is detected that the measurement value of the physiological parameter different from the physiological parameter 1 is significantly different from the historical measurement value, which is not limited herein.

[0283] In some application scenarios, the electronic device 100 can also receive and respond to the operation of the user viewing the historical evaluation result to display the historical evaluation result. The historical evaluation result can be the evaluation result of the physiological parameter 1 in one or more periods before the current period. Optionally, while displaying the historical evaluation result, the electronic device 100 can also display the fluctuation of the physiological parameter 1 in the current period relative to the period corresponding to the currently displayed historical evaluation result.

[0284] In this way, it is convenient for the user to understand the fluctuation of the physiological parameter 1 in different time periods, and it is also convenient for the user to understand the fluctuation of the physiological parameter 1 between multiple periods.

[0285] For example, as shown in FIG. 10A, the electronic device 100 displays the blood pressure evaluation result interface 740, which can display the blood pressure fluctuation graph 741 of the current period (e.g., 10:00-14:00). The specific description of the blood pressure fluctuation graph 741 can be referred to the related description in the embodiment shown in FIG. 7F, which is not described herein again.

[0286] The electronic device 100 can receive and respond to the right swipe operation of the user to display the blood pressure evaluation interface 1000 as shown in FIG. 10B.

[0287] As shown in FIG. 10B, the blood pressure evaluation interface 1000 can display a blood pressure fluctuation graph 1001 of a previous period (e.g., 06:00-10:00) of the current period (e.g., 10:00-14:00). The blood pressure fluctuation graph 1001 can be used to indicate the fluctuation trend of the systolic pressure and diastolic pressure of 06:00-10:00. The specific content of the blood pressure fluctuation graph 1001 can be analogously described with reference to the blood pressure fluctuation graph 741 shown in FIG. 7F, which will not be repeated here. Optionally, the blood pressure evaluation interface 1000 can also display a blood pressure comparison result 1002, which is used to indicate the blood pressure change of the current period relative to the previous period, for example, the blood pressure comparison result 1002 can include the text “compared with the 06:00-10:00 period, the blood pressure of the 10:00-14:00 period rises”.

[0288] In some other embodiments, the electronic device 100 can receive and respond to a rightward swiping operation of the user on the blood pressure evaluation result interface 740 shown in FIG. 10A to display a blood pressure evaluation interface 1010 as shown in FIG. 10C.

[0289] As shown in FIG. 10C, the blood pressure evaluation interface 1010 can display a blood pressure fluctuation graph 1011, and the time period corresponding to the blood pressure fluctuation graph 1011 can be a period, which can include a part of the current period (e.g., 10:00-14:00) and a part of the period before the current period. For example, the time period of the blood pressure fluctuation graph 1011 can be 08:00-12:00. The blood pressure fluctuation graph 1011 can be used to indicate the fluctuation trend of the systolic pressure and diastolic pressure of 08:00-12:00. The specific content of the blood pressure fluctuation graph 1011 can be analogously described with reference to the blood pressure fluctuation graph 741 shown in FIG. 7F, which will not be repeated here. Optionally, the blood pressure evaluation interface 1010 can also display a blood pressure comparison result 1012, which is used to indicate the blood pressure change of the current period (e.g., 10:00-14:00) relative to the time period corresponding to the blood pressure fluctuation graph 1011, for example, the blood pressure comparison result 1012 can include the text “compared with the 08:00-12:00 period, the blood pressure of the 10:00-14:00 period rises”.

[0290] It can be understood that the embodiments shown in FIGS. 10A-10C are only two examples. In the embodiments of the present application, the physiological parameter 1 can also be other physiological parameters besides blood pressure, the period can also be different from the above-mentioned embodiments, and the fluctuation trend of the physiological parameter 1 can also be different from the above-mentioned embodiments, which are not limited herein.

[0291] In some application scenarios, the time period corresponding to one cycle of the electronic device 100 can be changed in real time based on the current time. If the electronic device 100 receives an operation of the user viewing the evaluation result, the electronic device 100 can take the current time as the end time of the current cycle, determine the time period corresponding to the current cycle based on the preset time length of one cycle (for example, 2 hours, 4 hours, or 24 hours, etc.), and display the evaluation result of the user's physiological parameter 1 in the time period corresponding to the current cycle.

[0292] In this way, the user can obtain the blood pressure evaluation result (or the evaluation result of other physiological parameters) in a fixed time period before the current time in real time, which helps the user to understand their own health status.

[0293] For example, if the preset time length of one cycle is 2 hours, and at 12:08, the electronic device 100 receives an operation of the user viewing the blood pressure evaluation result (for example, the click operation on the evaluation result control 804 in the embodiment shown in FIG. 8B, or the click operation on the evaluation result control 723 in the embodiment shown in FIG. 7C, etc.), the blood pressure evaluation result interface 1020 shown in FIG. 10D can be displayed.

[0294] As shown in FIG. 10D, the blood pressure evaluation result interface 1020 can display the blood pressure fluctuation graph 1021 corresponding to the time period 10:08-12:08, which is used to indicate the blood pressure values at each time in the time period 10:08-12:08 and the blood pressure fluctuation trend in the time period. The other contents of the blood pressure evaluation result interface 1020 can refer to the related description in the embodiment shown in FIG. 7F, which will not be described here.

[0295] For another example, still taking the preset time length of one cycle as 2 hours, if at 13:15, the electronic device 100 receives an operation of the user viewing the blood pressure evaluation result again (for example, the click operation on the evaluation result control 804 in the embodiment shown in FIG. 8B, or the click operation on the evaluation result control 723 in the embodiment shown in FIG. 7C, etc.), the blood pressure evaluation result interface 1030 shown in FIG. 10E can be displayed.

[0296] As shown in FIG. 10E, the blood pressure evaluation result interface 1030 can display the blood pressure fluctuation graph 1031 corresponding to the time period 11:15-13:15, which is used to indicate the blood pressure values at each time in the time period 11:15-13:15 and the blood pressure fluctuation trend in the time period. The other contents of the blood pressure evaluation result interface 1030 can refer to the related description in the embodiment shown in FIG. 7F, which will not be described here.

[0297] It can be understood that the embodiments shown in FIGS. 10D-10E are only illustrative, and the monitoring period corresponding to the blood pressure evaluation result displayed by the electronic device 100 can not be a pre-divided period, but a period that is updated in real time with the time when the user views the evaluation result as the end time. In the embodiments of the present application, the physiological parameter 1 can also be a physiological parameter different from blood pressure, and the length of a period can also be different from the length of the period in the above embodiments, which is not limited herein.

[0298] In some other application scenarios, the electronic device 100 can output a measurement prompt when it is detected that a period (for example, the time period 1) is about to end and the measurement value of the physiological parameter 1 has not been obtained. The measurement prompt can be used to prompt the user to measure the physiological parameter 1 to obtain the measurement value of the physiological parameter 1. In some other embodiments, the electronic device 100 can output an input prompt when it is detected that a period (for example, the time period 1) is about to end and the measurement value of the physiological parameter 1 has not been obtained. The input prompt can be used to prompt the user to input the measurement value of the physiological parameter 1.

[0299] In this way, the electronic device 100 can remind the user to complete the measurement of the physiological parameter 1 in real time, and obtain the measurement value of the physiological parameter 1, so as to obtain the evaluation result of the physiological parameter 1 in the current period.

[0300] For example, as shown in FIG. 11A, the electronic device 100 can display a measurement prompt interface 1100, which can include a measurement prompt 1101 and a measurement blood pressure control 1102, and optionally, an input blood pressure control 1103. The measurement prompt 1101 can be used to prompt the user to measure the blood pressure. The measurement prompt 1101 can include text, for example, “The PPG signal in the current period has been collected. Please measure the blood pressure”. The measurement blood pressure control 1102 can be used to trigger the electronic device 100 to measure the blood pressure of the user and determine the blood pressure measurement value. The input blood pressure control 1103 can be used to trigger the electronic device 100 to display a blood pressure input interface for receiving the blood pressure measurement value input by the user.

[0301] In some embodiments, the electronic device 100 can receive and respond to the click operation of the user on the input blood pressure control 1103 to display the blood pressure input interface 1110 as shown in FIG. 11B.

[0302] As shown in FIG. 11B, the blood pressure input interface 1110 can include a blood pressure input box 1111 and an input completion control 1113, and optionally, a measurement time input box 1112. The blood pressure input box 1111 can be used to receive and display the blood pressure measurement value input by the user. Optionally, the blood pressure input box 1111 can also display a text prompt, for example, “input blood pressure”, which can be used to prompt the user to input the blood pressure measurement value in the blood pressure input box 1111. The measurement time input box 1112 can be used to receive and display the measurement time input by the user. Optionally, the measurement time input box 1112 can also display a text prompt, for example, “input measurement time”, which can be used to prompt the user to input the measurement time of the blood pressure measurement value in the measurement time input box 1112. The input completion control 1113 can be used to trigger the electronic device 100 to display the blood pressure evaluation result of the current period based on the blood pressure measurement value input by the user.

[0303] In some embodiments, after the user inputs the blood pressure measurement value, the electronic device 100 can receive and respond to the user's click operation on the input completion control 1113 to display the blood pressure evaluation result interface 730 shown in FIG. 7D or the blood pressure evaluation result interface 740 shown in FIG. 7F.

[0304] For another example, the electronic device 100 can display the measurement prompt interface 1100 shown in FIG. 11C. The specific content of the measurement prompt interface 1100 can refer to the specific description in the above-described embodiment shown in FIG. 11A, which will not be described here again.

[0305] In other embodiments, the electronic device 100 can receive and respond to the user's click operation on the blood pressure measurement control 1102 to display the operation prompt interface 1120 shown in FIG. 11D.

[0306] As shown in FIG. 11D, the operation prompt interface 1120 can display an operation prompt, which can include a text prompt 1121 and / or a picture prompt 1122. The text prompt 1121 and / or the picture prompt 1122 can be used to prompt the user to perform the measurement operation. For example, the text prompt 1121 can include the text “please measure the blood pressure according to the operation instruction”. The picture prompt 1122 can be the picture shown in FIG. 11D, which is used to instruct the user to touch two keys of the electronic device 100 with two fingers of the hand that does not wear the electronic device 100 to complete the blood pressure measurement. It can be understood that the operation prompt shown in FIG. 11D is only an example, and in the embodiments of the present application, the operation prompt can also take different forms from the above-described embodiments, for example, an animation prompt, a vibration prompt, etc., which are not limited herein.

[0307] In some application scenarios, the electronic device 100 can further receive and respond to a user operation of viewing the valid measurement times to display the valid measurement times of the current period (or the last period), where the valid measurement times refer to the valid measurement times of the PPG module of the electronic device 100 in a period. It should be noted that the electronic device 100 can be regarded as one valid measurement when obtaining one PPG signal. Alternatively, the electronic device 100 can further display a valid measurement period, and when the valid measurement times in a preset time period reach a preset number (for example, 1 valid measurement in 1 hour, or 3 valid measurements in 2 hours, etc.), the time period can be determined as the valid measurement period. In this way, the user can obtain the valid measurement times, and determine the accuracy of the evaluation result of the current period based on the valid measurement times.

[0308] For example, as shown in FIG. 12A, the electronic device 100 displays a blood pressure evaluation result interface 1200. The blood pressure evaluation result interface 1200 can include the evaluation result of the current period, which can include any one or more of the following: for example, the risk level 1202, the reference value 1203, the monitoring period 1204, the fluctuation compared with the last period 1205, etc. The blood pressure evaluation result interface 1200 can further include a valid measurement control 1206. The specific functions of the risk level 1202, the reference value 1203, the monitoring period 1204, and the valid measurement control 1206 can be similar to the related descriptions in the above-mentioned embodiment of FIG. 7E, except that the evaluation result of the current period in the embodiment shown in FIG. 12A is different from the evaluation result in the embodiment shown in FIG. 7E. In addition, the fluctuation compared with the last period 1205 can be used to indicate the fluctuation of the evaluation result of the current period compared with the last period, for example, “decrease”.

[0309] The electronic device 100 can receive and respond to a user click operation on the valid measurement control 1206 to display a valid measurement interface 1210 as shown in FIG. 12B.

[0310] As shown in FIG. 12B, the effective measurement interface 1210 can include an indication diagram 1211, and optionally, a text indication 1212. The indication diagram 1211 can be used to indicate the effective measurement period in a period (e.g., 24 hours), and the effective measurement period can be used to indicate the period in which the effective measurement is performed. For example, the indication diagram 1211 can include 24 dots arranged in a ring, and each dot can represent an hour (e.g., 3 o'clock, 6 o'clock, etc.). In the indication diagram 1211, one or more indicators 1211a can be used to indicate the period in which the effective measurement is performed (i.e., the effective measurement period). The indicator 1211a can be a ring-shaped pattern (or a pattern of other shapes), and the dots included in the ring-shaped pattern can correspond to the effective measurement period. Optionally, the indicator 1211a can determine the fill color of the indicator 1211a based on whether the period included in the indicator 1211a is a day or night. For example, when the period included in the indicator 1211a is a day, the fill color of the indicator 1211a can be white; and when the period included in the indicator 1211a is a night, the fill color of the indicator 1211a can be black. It can be understood that the above embodiment is only an example, and in the present embodiment, the indicator 1211a can also have a fill color different from the above embodiment, or the electronic device 100 can also use an indicator of a shape or form different from the above embodiment, which is not limited in the present application. The text indication 1212 can be used to indicate the number of effective measurements, for example, "17 times". Optionally, the text indication 1212 can also be used to indicate the period corresponding to the currently displayed effective measurement interface, for example, "June 17". Further optionally, the text indication 1212 can also be used to indicate the proportion of the number of effective measurements (or the effective measurement period) of the PPG module in a period, for example, "75%".

[0311] It can be understood that the embodiments shown in FIGS. 12A-12B are only examples, and in the present embodiment, the indication diagram 1211 of the effective measurement can also have a form different from the above embodiment, and the text indication 1212 of the effective measurement can also include more, less or different content than the above embodiment, which is not limited in the present application. In addition, the electronic device 100 can also open the effective measurement interface through other entrances, which is not limited in the present application.

[0312] In some other embodiments, the electronic device 100 can also receive and respond to a click operation of the user on the effective measurement control 1206 shown in FIG. 12A to display the effective measurement interface 1220 shown in FIG. 12C.

[0313] As shown in FIG. 12C, the effective measurement interface 1220 can include a monitoring period 1221, an effective measurement proportion 1222, an effective measurement times 1223, and the like. Optionally, the effective measurement interface 1220 can further include any one or more of the following: a return control 1226, a daytime effective measurement indication diagram 1224, a nighttime effective measurement indication diagram 1225, and the like. The monitoring period 1221 can be used to indicate the monitoring period (i.e., a period) corresponding to the current effective measurement interface, for example, “June 17”. The effective measurement proportion 1222 can be used to indicate the proportion of the effective measurement times (or the effective measurement period) in the monitoring period. The effective measurement times 1223 can be used to indicate the effective measurement times in the monitoring period. The return control 1226 can be used to trigger the electronic device 100 to return to the previous interface, for example, the blood pressure evaluation result interface 1200 shown in FIG. 12A. The daytime effective measurement indication diagram 1224 can be used to indicate the effective measurement times in the daytime (for example, 06:00-19:00). The nighttime effective measurement indication diagram 1225 can be used to indicate the effective measurement times in the nighttime (for example, 19:00-06:00). For example, the daytime effective measurement indication diagram 1224 can be a ring diagram, which can be divided into multiple parts, for example, evenly divided into 7 parts. The daytime effective measurement indication diagram 1224 can indicate the effective measurement times in the daytime of the current monitoring period (i.e., June 17) by the number of parts filled with color (for example, filled with blue or white, etc.). Similarly, the nighttime effective measurement indication diagram 1225 can also be a ring diagram divided into multiple parts, and the nighttime effective measurement indication diagram 1225 can indicate the effective measurement times in the nighttime of the current monitoring period (i.e., June 17) by the number of parts filled with color (for example, filled with black or purple, etc.).

[0314] In some other application scenarios, when the electronic device 100 detects that no measurement value of the physiological parameter 1 is measured in a period of time (for example, 1 hour, or 2 hours, etc.), the electronic device 100 can display a measurement prompt, prompting the user that the past period of time is an invalid measurement period, and prompting the user to actively measure. In this way, at least one effective measurement data in a period can be ensured, and the evaluation result can be ensured to be obtained.

[0315] For example, when the electronic device 100 detects that no effective measurement value is collected in the past 1 hour, the electronic device 100 can display a measurement prompt interface 1230 as shown in FIG. 12D.

[0316] As shown in FIG. 12D, the measurement prompt interface 1230 can include a measurement prompt 1231, and can further include a blood pressure measurement control 1232. The measurement prompt 1231 can be used to prompt the user that no blood pressure measurement value has been acquired in the past 1 hour, and prompt the user to actively measure. For example, the measurement prompt 1231 can include the text "It is detected that your activity amplitude is large in the past 1 hour, and no valid data is acquired, and it is suggested that you manually measure once".

[0362] The following describes a physiological parameter measurement method provided by an embodiment of the present application.

[0363] FIG. 16 shows a flowchart of a physiological parameter measurement method provided by an embodiment of the present application.

[0364] As shown in FIG. 16, the specific process of a physiological parameter measurement method can include the following steps:

[0365] S1601. The first electronic device acquires a first PPG signal of a first time period based on a first PPG module, and the first electronic device includes a first photoplethysmography (PPG) module.

[0366] Photoplethysmography (PPG) is a technology that uses an optical sensor to sense the change of hemoglobin concentration flowing inside the blood vessels on the surface of the human body, so as to obtain the pulse of the human body. More and more devices are now equipped with PPG modules to collect PPG signals, and then use the PPG signals to analyze the physiological parameters of the user such as blood oxygen saturation, heart rate, respiratory rate, blood pressure, blood sugar, muscle oxygen, vascular resistance, brain oxygen, etc.

[0367] The first electronic device can be the electronic device 100 in the above-described embodiments.

[0368] Exemplarily, the first time period can be the time period 1 in the above-described embodiment of FIG. 4.

[0369] S1602. The first electronic device determines first estimation data based on the first PPG signal, the first estimation data comprising a plurality of estimated values of the first physiological parameter in a first time period.

[0370] For example, the first estimation data can be the set of estimated values A1 in the embodiment shown in FIG. 4.

[0371] S1603. The first electronic device determines a first measurement value of the first physiological parameter at a first time point, the first time point belonging to the first time period.

[0372] It should be noted that steps S1602 and S1603 can be executed in parallel, or step S1602 can be executed first and then step S1603, or step S1603 can be executed first and then step S1602, and the specific execution order of steps S1602 and S1603 is not limited in the present application.

[0373] In some embodiments, the first time point can be a time point in the first time period, in which case the first electronic device can execute step S1603 during the execution of step S1602. In some embodiments, the first time point can be an ending time point of the first time period, in which case the first electronic device can execute step S1603 after executing step S1602. In some embodiments, the first time point can be a starting time point of the first time period, in which case the first electronic device can execute step S1603 before executing step S1602.

[0374] For example, the first time point can be time point 1 in the embodiment shown in FIG. 4, and the first measurement value can be measurement value 1 in the embodiment shown in FIG. 4.

[0375] S1604. The first electronic device determines a first evaluation result based on the first estimation data and the first measurement value, the first evaluation result comprising measurement values of the first physiological parameter at a plurality of time points in the first time period.

[0376] For example, the first evaluation result can be evaluation result 1 in the embodiment shown in FIG. 4.

[0377] It should be noted that the measurement values of the first physiological parameter at a plurality of time points in the first time period refer to the values of the first estimation data after calibration by the first measurement value. That is, the measurement values of the first physiological parameter are more accurate than the estimated values.

[0378] In this way, the first electronic device can monitor the first physiological parameter based on the PPG module, calibrate the data collected by the PPG module based on the first measurement value, obtain a plurality of measurement values of the first physiological parameter in the first time period, and obtain the fluctuation trend of the first physiological parameter in the first time period, so as to facilitate the user to know the health status in a timely manner.

[0379] In a possible implementation, the first electronic device further includes a first physiological module; and the first measurement value of the first physiological parameter at the first time point is determined by the first physiological module.

[0380] For example, the first physiological module can be the physiological module 196 in the electronic device 100 in the embodiment of FIG. 3A.

[0381] In this way, the first electronic device can measure the first measurement value of the first physiological parameter by the first physiological module, without the aid of other devices (such as medical devices), so that the application range of the physiological parameter measurement method is wider and more flexible. Moreover, the measurement is completed by a single electronic device, which is convenient for the user to carry the electronic device and measure in real time.

[0382] In a possible implementation, the first measurement value of the first physiological parameter at the first time point is determined by the first physiological module, specifically including: receiving a first operation of the first user measuring the first physiological parameter; and in response to the first operation, determining the first measurement value of the first physiological parameter at the first time point by the first physiological module.

[0383] For example, the first operation can be the click operation of the user on the blood pressure measurement control 711 in the embodiment shown in FIG. 7B.

[0384] In this way, the measurement can be completed in response to the measurement operation of the user, and the first measurement value is determined. The user can control the measurement time of the first measurement value according to the user's own situation.

[0385] In another possible implementation, the first measurement value of the first physiological parameter at the first time point is determined by the first physiological module, specifically including: detecting that the current time is the preset first time point, and determining the first measurement value of the first physiological parameter at the first time point by the first physiological module.

[0386] In this way, the user does not need to manually operate to complete the measurement without the user's awareness.

[0387] In a possible implementation, the first physiological module includes any one or more of the following: an electrocardiogram module, a second PPG module, a pressure sensor, and an air bag.

[0388] In this way, the first electronic device can measure the first physiological parameter based on the first physiological module.

[0389] In a possible implementation, the first measurement value of the first physiological parameter at the first time point is determined, specifically including: receiving a second operation of the first user; and determining the first measurement value of the first physiological parameter at the first time point in response to the second operation.

[0390] For example, the second operation can be the input operation of the user on the blood pressure input box 1111 in the embodiment shown in FIG. 11B.

[0391] In this way, the first measurement value can be determined based on the input of the user. The input of the user can include the first measurement value, and optionally, the first time point.

[0392] In a possible implementation, the first measurement value of the first physiological parameter at the first time point is determined, specifically including: obtaining the first information sent by the second electronic device, the first information including the first measurement value of the first physiological parameter at the first time point.

[0393] For example, the second electronic device can be the measurement device 200 in the above embodiment.

[0394] In this way, the first measurement value can be obtained through other electronic devices (for example, medical devices, other wearable devices, etc.).

[0395] In a possible implementation, the first information sent by the second electronic device is obtained, specifically including: sending a first request to the second electronic device, the first request being used to request to obtain one or more measurement values of the first physiological parameter within a first time period; and receiving a first response sent by the second electronic device, the first response including the first measurement value of the first physiological parameter at the first time point.

[0396] For example, the first request can be the request 1 in the embodiment shown in FIG. 6, and the first response can be the response 1 in the embodiment shown in FIG. 6.

[0397] In this way, the first measurement value sent by the second electronic device can be obtained by sending the first request.

[0398] In a possible implementation, the method further includes: determining a second measurement value of the first physiological parameter at a second time point, the second time point belonging to the first time period; and determining the first evaluation result based on the first estimation data and the first measurement value, specifically including: determining the first evaluation result based on the first estimation data, the first measurement value and the second measurement value.

[0399] In this way, the first estimation data can be calibrated through two (or more than two) measurement values, the accuracy of the calibration is improved, and a more accurate first evaluation result is obtained.

[0400] In a possible implementation, the method further includes: outputting the first evaluation result.

[0401] In this way, the first evaluation result can be outputted after the first evaluation result is determined, so that the user can view the first evaluation result and understand the health status in real time.

[0402] In a possible implementation, the outputting of the first evaluation result specifically includes: outputting any one or more of the following: a first waveform graph, a risk level, a first time period, a reference value, a valid measurement number, and a valid measurement time period; the first waveform graph is used to indicate the fluctuation trend of the first physiological parameter in the first time period, the risk level is used to indicate whether the measurement value of the first physiological parameter in the first time period is risky, the reference value is used to indicate the mean value of the first physiological parameter in the first time period, the valid measurement number is used to indicate the valid measurement number of the first PPG module in the first time period, and the valid measurement time period is used to indicate the valid measurement time period of the first PPG module in the first time period.

[0403] In this way, the user can be provided with more detailed information by outputting any one or more of the waveform graph, the risk level, the reference value, the valid measurement number, and the like, so that the user can understand the health status.

[0404] The specific manner in which the first electronic device outputs the first evaluation result and the specific content of the first evaluation result can refer to the related description in the above-described step S405 shown in FIG. 4, the embodiments of FIGS. 7D-7F, and FIGS. 12B-12C, which will not be described herein again.

[0405] In a possible implementation, the method further includes: receiving and responding to a third operation of the first user to display a second waveform graph, the second waveform graph being used to indicate the fluctuation trend of the first physiological parameter in a second time period, the length of the second time period being the same as that of the first time period, and the second time period being earlier than the first time period.

[0406] For example, the third operation can be the rightward sliding operation in the above-described embodiment shown in FIG. 10A, and the second waveform graph can be the blood pressure fluctuation graph 1001 shown in FIG. 10B or the blood pressure fluctuation graph 1011 in the above-described embodiment shown in FIG. 10C.

[0407] In this way, the fluctuation trend and the evaluation result of the first physiological parameter in the past time period can be viewed. Optionally, the comparison result (for example, rising, falling, or stable) of the first physiological parameter in the current time period and the last time period can also be viewed.

[0408] In a possible implementation, the second time period does not overlap with the first time period, or the second time period overlaps with the first time period.

[0409] The specific relationship between the second time period and the first time period can also be referred to in relation to the description of the embodiments shown in FIGS. 10A-10C.

[0410] In this way, the user can view the fluctuation trend of the first physiological parameter in different time periods in the past through the user operation.

[0411] In a possible implementation, the end moment of the first time period is the first moment, and the duration of the first time period is a preset duration.

[0412] The time period corresponding to the first time period can be referred to in relation to the description of the embodiments shown in FIGS. 10D or 10E.

[0413] In this way, the first time period can be determined based on the first moment of the first measurement value, so as to determine the first evaluation result of the first time period.

[0414] In a possible implementation, the first physiological parameter includes any one or more of the following: blood pressure, heart rate, blood oxygen saturation, respiratory rate, blood glucose, muscle oxygen, vascular resistance, and brain oxygen.

[0415] Therefore, the first electronic device can determine the estimated data of any one or more of the physiological parameters through the PPG signal, and calibrate the estimated data based on the measurement value of the physiological parameter to obtain the evaluation value of the physiological parameter.

[0416] In a possible implementation, the method further includes: receiving a fourth operation of the second user; in response to the fourth operation, obtaining a third measurement value of the first physiological parameter of the second user; and displaying the third measurement value.

[0417] The fourth operation can be the click operation on the friend measurement control 713 in the embodiment shown in FIG. 9A.

[0418] The interface for displaying the third measurement value can be the blood pressure measurement result interface 900 in the embodiment shown in FIG. 9B.

[0419] In this way, the first physiological parameter of the non-native user can be measured by the first electronic device, and the third measurement value can be obtained and output. The second user is a non-native user, and the second user is different from the first user. In this case, the first electronic device will store the third measurement value separately to avoid confusion with the measurement data of the native user (i.e., the first user).

[0420] In a possible implementation, after obtaining the third measurement value of the first physiological parameter of the second user, the method further includes: determining that the current user is not the first user based on the third measurement value; and marking the third measurement value as non-native user measurement data.

[0421] In this way, the measurement data of the native user (i.e. the first user) can be avoided from being confused.
