The most important idea of the application is to apply the blood pressure watch to the monitoring of continuous blood pressure so as to conveniently obtain a calibrated blood pressure value.

Example one
Referring to the embodiments shown in fig. 1 to 6, the embodiment provides a blood pressure wristwatch 100, and the blood pressure wristwatch 100 includes a wristwatch case 110, a watchband 120, a synchronous timing mark device 130, an electrocardiogram detection device 140a, a pulse wave detection device 140b, a blood pressure measurement device 150, and a first processor 160.
The watch case 110 is connected to the band 120, the band 120 can be bent to wrap around the wrist, and the watch case 110 provides a space for various functional devices in the blood pressure watch 100.
The synchronous timing device 130 is used to provide a timing signal, which refers to a standard time signal used as a time reference for respective operations of different devices or different modules. In some embodiments, the synchronous timing device 130 may be a clock circuit of the blood pressure watch 100, and the timing signal is generated by the clock circuit, i.e., in this example, the timing signal is generated by the blood pressure watch 100 itself, or in other embodiments, the timing signal may not be provided by the blood pressure watch 100, and may be transmitted to the blood pressure watch 100 in a satellite timing manner, for example.
The electrocardiograph detection device 140a is used to obtain the time scale signal and the electrocardiograph signal of the user. In this embodiment, the manner of obtaining the electrocardiographic signal is not improved, and any suitable electrocardiographic detection device 140a that can be placed in the blood pressure watch 100 at present can be applied to this embodiment. In some embodiments, as shown in fig. 3 and 4, the electrocardiograph detection device 140a includes a first electrode 141, a second electrode 142, and a signal acquisition device (not shown in the drawings), the signal acquisition device is located in the watch case 110, the signal acquisition device is respectively connected to the first electrode 141 and the second electrode 142, and the first electrode 141 and the second electrode 142 are used for simultaneously contacting with the skin of the user (for example, in fig. 3 and 4, the user contacts the first electrode 141 when wearing the blood pressure watch, and then can contact the second electrode 142 by itself), so as to form a measurement loop. In other embodiments, any one of the first electrode 141 and the second electrode 142 may be connected to a signal acquiring device through an electrical connection line, for example, as shown in fig. 3 and 5, intuitively, one electrode may extend from the blood pressure watch 100, a distance between the two electrodes on the human body is defined as D, the signal acquiring device is configured to obtain an electrocardiograph signal according to an electrical signal in a loop, and an existing mature electrocardiograph signal acquiring algorithm may be stored in the signal acquiring device, so as to obtain the electrocardiograph signal through the electrocardiograph signal acquiring algorithm. In addition, the electrocardiograph detection device 140a may also be made into a detachable structure, an electrode interface electrically connected to the signal acquisition device is disposed on the watch housing 110, and the first electrode 141 and/or the second electrode 142 are/is detachably connected to the signal acquisition device through the electrode interface. By making the electrocardiograph detection device 140a detachable structure, two electrodes led out from the blood pressure watch 100 can be detached when electrocardiograph detection is not required, and the usability of the blood pressure watch 100 is improved.
After obtaining the electrocardiographic signal of the user, the electrocardiograph detecting device 140a further determines the relationship between the electrocardiographic signal and time according to the time scale signal, that is, determines the magnitude or value of the electrocardiographic signal at each time based on a reference time point. In addition, in some embodiments, the relationship between the electrocardiographic signal and the time can also be determined in a pure hardware manner, for example, a clock synchronization circuit is used to determine the relationship between the electrocardiographic signal and the time, the electrocardiographic signal serves as one input of the clock synchronization circuit, the time scale signal serves as the other input of the clock synchronization circuit, and finally the electrocardiographic signal which changes with time is output.
The pulse wave detection device 140b is used for acquiring the time scale signal and the pulse wave signal of the user.

The existing mature algorithm can also realize the determination of the relationship between the pulse wave signal and the time according to the time scale signal.
The blood pressure measuring device 150 is used to obtain calibrated blood pressure values required for continuous blood pressure measurement. It should be noted that, in this embodiment, the algorithm for obtaining the calibrated blood pressure value is not improved, but the calibrated blood pressure value may be obtained by using the existing mature algorithm for obtaining the blood pressure value. Of course, the blood pressure measuring device 150 also needs to obtain a time mark signal in order to determine the obtained relation between the calibrated blood pressure value and the time.
In some embodiments, referring to fig. 6, the blood pressure measurement device 150 includes a pulse pressure acquisition component 1520 and a blood pressure calculation circuit 1540.
The pulse pressure acquisition assembly 1520 includes a bladder 1522, an air pump 1524, a pressure sensing assembly 1526 and an exhaust valve 1528. An air pump 1524, a pressure sensing assembly 1526 and an exhaust valve 1528 may also be disposed within the watch case 110. The pressure sensing component 1526 is used for collecting the pulse pressure signal of the user. The exhaust valve 1528 is used for closing or opening the communication between the air bag 1522 and the outside so as to exhaust the air bag 1522 in an open state, namely the air bag 1522 starts to be decompressed after the exhaust valve 1528 is opened. In some embodiments, the exhaust valve 1528 may be an electrically controlled exhaust valve or a mechanical exhaust valve, which has the advantage of not consuming energy. In some embodiments, the pressure sensing assembly 1526 includes a pressure sensor in communication with the bladder 1522 for collecting a pressure analog signal and an analog-to-digital conversion circuit for converting the pressure analog signal into a pressure digital signal, i.e., collecting a pulse pressure signal through the above process.

As can be seen from the above description, in the present embodiment, the calibrated blood pressure value required for continuous blood pressure measurement is conveniently obtained by using the blood pressure watch 100, so that the operation of continuous blood pressure measurement becomes more convenient and feasible.
After obtaining the synchronized ecg signal and the pulse wave signal, the first processor 160 first calculates a pulse wave conduction time according to the synchronized ecg signal and the pulse wave signal, and then calculates a pulse wave conduction velocity according to the distance D, and finally, the first processor 160 may obtain a parameter related to continuous blood pressure measurement according to the calibrated blood pressure value and the pulse wave conduction velocity, where the parameter related to continuous blood pressure measurement includes, but is not limited to, at least one of a blood pressure measurement value, a pressure index, and an arteriosclerosis index within a continuous time. Also, it should be noted that the above algorithm for calculating the pulse transit time, the pulse transit velocity and the parameters related to the continuous blood pressure measurement is also a well-established algorithm, and the first processor 160 can receive corresponding input and obtain output by using the existing algorithm.
In some embodiments, the synchronous timing mark device 130 is also used to record the operating time of the blood pressure watch 100, e.g., the synchronous timing mark device 130 may determine that it is currently beijing hours for hours of minutes of seconds while the blood pressure watch 100 is in use. The first processor 160 is further configured to determine whether to send a first control signal to the blood pressure measurement device 150 according to the operating time of the blood pressure watch 100, where the first control signal is used to control the blood pressure measurement device 150 to obtain a calibrated blood pressure value. Specifically, some time points may be preset, and when the working time reaches these preset time points, the first processor 160 sends the first control signal to the blood pressure measuring device 150, for example, 10 points in beijing, 10 points 05, 10 points 10 may be set as the preset time points, and the blood pressure measuring device 150 obtains the calibrated blood pressure value of the user every time these preset time points are reached. In some embodiments, the first control signal may be a high signal, and the blood pressure measuring device 150 starts to obtain a calibrated blood pressure value when receiving the high signal.
The manner of obtaining the calibrated blood pressure value may be referred to as obtaining the calibrated blood pressure value periodically, and the advantage of obtaining the calibrated blood pressure value periodically is that the accuracy of the parameters related to the continuous blood pressure measurement can be improved by updating the calibrated blood pressure value periodically.
In other embodiments, the blood pressure watch 100 may further include an exercise monitoring device 170, the exercise monitoring device 170 is configured to obtain exercise information representing the exercise intensity of the body of the user, the first processor 160 is configured to determine whether to send a second control signal to the blood pressure measuring device 150 according to the exercise information, the second control signal is configured to control the blood pressure measuring device 150 to obtain a calibrated blood pressure value, for example, the first processor 160 may compare the exercise information with a preset exercise intensity threshold value, and send the second control signal to the blood pressure measuring device 150 when the exercise information exceeds the exercise intensity threshold value. The motion monitoring device 170 includes at least one of a 3D sensor, a PPG sensor, an ecg sensor, a blood oxygen sensor, and a respiration sensor, and the motion information includes at least one of heart rate variation, ecg waveform variation, and pulse wave propagation time, corresponding to the at least one of the 3D sensor, the PPG sensor, the ecg sensor, the blood oxygen sensor, and the respiration sensor. In some embodiments, the second control signal may be a high signal, and the blood pressure measurement device 150 starts to obtain the calibrated blood pressure value when receiving the high signal.
At present, the determination of a calibration time machine for continuous blood pressure measurement is difficult to master, for example, the intermittent non-invasive blood pressure measurement and the re-calibration are required to be carried out by re-using an auscultation method or an oscillography method when rising from a seat, sitting after walking, holding back urine, changing emotion a little bit more and the like, and the determination of whether to obtain the calibrated blood pressure value according to the body movement strength of a user can reduce unnecessary blood pressure measurement processes, so that the obtaining time of the calibrated blood pressure value is more appropriate.
In some examples, the ecg detection device 140a includes, in addition to the first processor 160, a second processor for obtaining the time stamp signal and the ecg signal of the user, i.e., the second processor is configured to execute an algorithm for obtaining the ecg signal; the pulse wave detection device 140b includes a third processor, which is used for acquiring the time scale signal and the pulse wave signal of the user, i.e. the third processor is used for executing the algorithm for acquiring the pulse wave signal; the blood pressure measurement device 150 further comprises a fourth processor for obtaining nominal blood pressure values of the user required for the continuous blood pressure measurement. Any one of the first processor, the second processor, the third processor and the fourth processor doubles as at least one of the other three.
