(shown in cross-section) surface to sense the real-time pressure of the blood in the radial artery 620.

Then in step S730, during the pressing process of the first sensor assembly and the second sensor assembly, the information processing assembly monitors the first pulse signal through the first sensor assembly, and monitors the first pulse signal through the second sensor assembly. The sensor assembly monitors the second pulse signal; in step S740, when the first pulse signal or the second pulse signal meets a threshold condition (for example, as the pressure of the sensor assembly gradually increases, the corresponding pulse signal is The amplitude gradually decreases to less than a preset amplitude threshold, in other words, the blood vessel wall is subjected to approximately equal pressures from the blood and the sensor component, then it is determined that the critical value condition is satisfied (refer to FIG. 9), and the information processing component passes the first sensor The assembly or the second sensor assembly acquires a second blood pressure value.

In step S750, the information processing component takes the first blood pressure value as diastolic blood pressure and takes the second blood pressure value as systolic blood pressure.

In some embodiments, considering that there may be differences between the left and right sides during the work process and the work is not synchronized (for example, one side is stuck), independent pressure work on both sides can be set to achieve functional redundancy, thereby reducing or avoiding mechanical The failure affects the acquisition process. In the above step S710, the information processing component sends a first collection instruction to the first collection component, and sends a second collection instruction to the second collection component; wherein the first driving device drives the first collection instruction based on the first collection instruction The first sensor assembly moves in the direction of pressing the radial surface of the user's left hand, and the second driving device drives the second sensor assembly to move in the direction of pressing the radial surface of the user's right hand based on the second acquisition instruction.

For the process of collecting ECG data, the collecting device includes a first electrode and a second electrode respectively disposed on the left and right holding parts. Correspondingly, in some embodiments, the above method further includes step S760 (not shown). Specifically, in this step S760, the information processing component collects the ECG information of the user through the first electrode and the second electrode; wherein the first electrode is arranged on the first holding part of the first collecting component, the first electrode is The two electrodes are arranged on the second holding part of the second collecting component. For example, continuing to refer to FIG. 6 , the output of the comparator circuit is the ECG information collected based on the first electrode and the second electrode, and the ECG information is amplified as the user's ECG data. FIG. 10 shows the variation of the waveform amplitude of the ECG information (increasing gradually and then gradually decreasing) as the sensor assemblies on the left and right sides gradually increase and then decrease the pressure on the user's wrist.

For the sake of intuition, Fig. 11 shows several situations in which the amplitudes of the ECG information waveforms are different under the situation that the sensor assembly exerts different pressures. Among them, curve A indicates that the corresponding sensor component has not detected any pulse, and the waveform is a straight line; curve B indicates the signal waveform when the corresponding sensor component first detects the pulse, for example, the pulse signal sensed by the sensor component just reaches the sensor component at this time. , so that the output of the sensor assembly begins to change; curve C represents the detected signal waveform as the pressure applied by the sensor assembly to the user's wrist increases; curve D represents the pressure applied to the user's wrist by the sensor assembly. The signal waveform with the largest amplitude that can be detected in the process of increasing pressure. Among them, as the pressure applied by the sensor component gradually increases, the ECG information waveform starts from curve A, gradually changes from curve B and curve C to curve D, and then gradually changes from curve D to curve C and curve B until becomes as shown in curve A. At this time, the pressure felt by the corresponding sensor component when the ECG information waveform changed to curve B for the first time was taken as the first blood pressure value, and the pressure felt by the corresponding sensor component when the ECG information waveform changed to curve B for the second time was used as the above-mentioned first blood pressure value. The received pressure is used as the above-mentioned second blood pressure value. Therefore, based on the change of the waveform amplitude recorded by the acquisition device, the blood pressure value corresponding to the current pressure of the sensor assembly on the user's wrist can be easily determined.

In some embodiments, in order to prevent inaccurate measurement or measurement failure caused by the user's misoperation, the user needs to grasp both sides of the holding parts at the same time to start the acquisition work. Correspondingly, in the above step S710, the information processing component detects the lead state of the first electrode and the second electrode; if the first electrode and the second electrode form a lead, the information processing component controls the first sensor component moving in the direction of pressing the radial surface of the user's left hand, and controlling the second sensor assembly to move in the direction of pressing the radial surface of the user's right hand. Among them, in some embodiments, the user will loosen the grip on one or both sides during the measurement process due to discomfort or misoperation, in order to prevent the user from being injured due to system failure (for example, excessive pressure on the sensor assembly may cause discomfort to the user) ) or the measurement is inaccurate/failed, the above method further includes step S770 (not shown). In this step S770, if the lead of the first electrode and the second electrode is disconnected, the information processing component interrupts the blood pressure collection. Further, in order to ensure the safety of the user, the pressure exerted by the sensor assembly on the user's wrist may optionally be rapidly reduced. Specifically, the above device further includes an air pump, which is used to drive the first sensor assembly and the second sensor assembly to move by supplying air to the airbag; in the above step S770, if the first electrode and all the The lead of the second electrode is disconnected, the information processing component interrupts blood pressure collection, and controls the air pump to pump air from the air bag, thereby rapidly reducing the pressure exerted by the sensor component on the user's wrist.

Optionally, the sensor assemblies on the left and right sides are respectively provided with several sensor units to form a sensor array, so as to improve the success rate of the sensor assemblies in collecting valid pulse signals, and the user does not need to adjust the wrist angle to adapt to the sensor assemblies. Taking the first sensor assembly 140 as an example, the first sensor assembly 140 includes one or several (for example, 3) first sensor units 141, and the first sensor assembly 140 moves in the direction of the arrow in FIG. Cover the surface of the user's wrist (the state is shown in Figure 4 ); these first sensor units 141 are circumferentially distributed on the user's left wrist and are arranged toward the user's wrist surface, so as to provide a larger coverage area on the user's wrist surface and ensure that the user's wrist The radial pulse signal can be captured and collected by at least one sensor unit 141 to ensure high pulse signal collection efficiency. The second sensor assembly is similar, comprising several (eg, 3) second sensor units; these second sensor units are distributed circumferentially around the user's right wrist and are arranged towards the surface of the user's wrist. By analyzing whether the pressure information detected by the three sensor units on each side is regular, it can be determined whether the obtained sensing information of the corresponding sensor unit is ideal (the more regular the pressure information, the more ideal the corresponding sensing information). In the above step S730, the information processing assembly, during the pressing process of the first sensor assembly and the second sensor assembly, according to the sensing of the plurality of first sensor units and the plurality of second sensor units information, at least one first sensor unit is determined as the first target sensor unit, and at least one second sensor unit is determined as the second target sensor unit (for example, the first sensor unit with the most regular waveform is used as the first target sensor unit, and the waveform with the most regular waveform is used as the first target sensor unit. The regular second sensor unit is used as the second target sensor unit); then, the information processing unit monitors the first pulse signal through the first target sensor unit, and monitors the second pulse through the second target sensor unit Signal.
