Description
Technical Field
The application relates to the technical field of health monitoring, in particular to a wrist type wearable device and a control method of the wrist type wearable device.
Background
With the development of wrist wearable devices in recent years, many wrist wearable devices have health monitoring functions. The heart diseases are sudden and hidden, so that the degree of harm to human health is high, and the wrist wearable device is widely applied to monitoring and preventing the heart diseases.
Currently, a heart monitoring technology commonly used for wrist wearable devices is photoplethysmography (PPG), which can detect heart rate in a resting state and a moving state. With the improvement of the precision of the PPG detection, the PPG technology can be used for recording the Heart Rate so as to perform Heart Rate Variability (HRV) analysis, and meanwhile, the method is used for preventing and early warning simple abnormal Heart Rate diseases such as atrial fibrillation.
However, PPG can only record the frequency and pulse waveform of the heart beat, and the more complex symptoms of heart disease are not reflected in the heart rate data. In contrast, electrocardiography (ECG) is capable of more fully reflecting the state of the heart. When the ECG is used for examining the heart condition, the electrodes are needed to be arranged on the skin to monitor the voltage-time relationship of the electrical activity of the heart, and most heart diseases can be effectively identified, including heart rhythm disorders (such as atrial fibrillation and tachycardia), insufficient blood flow of coronary arteries (such as myocardial ischemia and myocardial infarction), electrolyte disorders (such as hypokalemia and hyperkalemia) and the like.
In clinical ECG medical examinations, an electrocardiogram is usually recorded for a short period of time (e.g., ten seconds), and most symptoms of heart diseases have a time uncertainty, so that it is necessary to monitor the heart condition in cooperation with a 24-hour medical ECG device. However, the conventional 24-hour medical ECG device is difficult to carry due to its large size, which makes it difficult to record ECG waveforms at any time. The wrist wearable device has the convenience of carrying about, can monitor the electrocardiogram waveform of the user as far as possible in real time, and has great value for monitoring the heart state. Therefore, it is an urgent problem to provide a wrist wearable device having an ECG function module and to improve the convenience of the wrist wearable device in ECG monitoring.

With the development of technology, health monitoring functions are increasingly applied to wrist wearable devices, and health monitoring functions of the wrist wearable devices are more abundant and accurate. The cardiac vector generated by the heart in the processes of electrode removing and electrode repolarizing is transmitted to each part of the body through volume conduction, and generates potential difference. The electrocardiogram can be traced by placing two electrodes at any two points of the human body and connecting them with an electrocardiograph, and the circuit for placing the electrodes and connecting them with the electrocardiograph is called the lead of electrocardiogram. The electrodes are placed at different positions of the human body, so that different leads can be obtained. The international common lead system has twelve leads, and the more the number of leads is, the more abnormal conditions of the heart can be reflected. In the prior art, wrist wearable equipment is provided with three electrodes, can only realize single-lead electrocardiogram test, can only obtain one-lead electrocardiogram waveform, and can only be used for detecting heart rate and obtaining a small amount of heart abnormal information such as atrial fibrillation, premature beat and the like. In addition, because the electrodes are needed to detect the electrical signals at more positions of the body to obtain the multi-lead electrocardiogram waveform of the voltage, in the prior art, a plurality of electrodes are arranged on one detector, the positions are concentrated, a user needs to keep a more awkward posture when using the electrocardiogram signal detector, the operation requirement of the user is higher, and the electrocardiogram signal detector is not suitable for people with inconvenient body. Therefore, the application provides the wrist type wearable device and the control method of the wrist type wearable device, so that the user can conveniently and rapidly carry out the electrocardio test, and the multi-lead electrocardio test can be realized.
The wrist wearable device and the control method of the wrist wearable device are suitable for health monitoring scenes, and users can capture electrocardiogram waveforms in abnormal heart anytime and anywhere by utilizing the portability of the wrist wearable device. When a user feels uncomfortable or abnormal in the sick state or a period of time before the sick state, the electrocardiogram detection function of the wrist wearable device can be started immediately, and waveform data can be acquired and stored in time to serve as basic data for further diagnosis and treatment and prevention. Alternatively, the electrocardiogram monitoring function of the wrist wearable device can be in a normally open state, that is, when the user wears the wrist wearable device, the electrocardiogram waveform of the user can be monitored and recorded.

Fig. 15 is a flowchart illustrating a control method of the wrist wearable device according to the embodiment of the present application, which is executed by the control circuit 120 of the wrist wearable device.
Referring to fig. 15, the control method specifically includes the following steps:
step S101, receiving a first electrical signal collected by a first electrode, a second electrical signal collected by a second electrode, a third electrical signal collected by a third electrode, and a fourth electrical signal collected by a fourth electrode.
When the user uses the wrist wearable device, the electrodes can be respectively contacted with the corresponding positions of the body, so that each electrode can acquire corresponding electric signals, and the control circuit can receive the electric signals acquired by the electrodes. For example, the control circuit may receive the first electrical signal collected by the first electrode 141, the second electrical signal collected by the second electrode 142, the third electrical signal collected by the third electrode 143, and the fourth electrical signal collected by the fourth electrode 144.
It should be noted that, in a possible implementation manner of the embodiment of the present application, the control circuit may start to receive the first electrical signal, the second electrical signal, the third electrical signal and the fourth electrical signal, that is, start to execute steps S101 to S103, when receiving the cardiac status monitoring command or a preset user operation. For example, the user may send a cardiac status monitoring command to the control circuit 120 through the external device 200 to trigger the control circuit 120 to start receiving the first electrical signal, the second electrical signal, the third electrical signal, and the fourth electrical signal, and execute S102-S103; or the user may also perform preset operations on modules such as a touch screen, a button, or a sensor of the wrist wearable device to trigger the cardiac state monitoring instruction, so that the control circuit starts to receive the first electrical signal, the second electrical signal, the third electrical signal, and the fourth electrical signal, and execute S102-S103.
In another possible implementation manner of this embodiment, the control circuit 120 may also receive the first electrical signal, the second electrical signal, the third electrical signal, and the fourth electrical signal in real time, but does not process the first electrical signal, the second electrical signal, the third electrical signal, and the fourth electrical signal, and does not execute S102-S103 until the control circuit receives a cardiac status monitoring command or a preset user operation. This is not a limitation of the present application.
And S102, determining first upper limb electric information, second upper limb electric information and body electric information below the heart according to the first electric signal, the second electric signal, the third electric signal and the fourth electric signal.
When calculating first upper limbs electric information, second upper limbs electric information and heart below body electric information, the first electrode can be as reference electrode, and then the first signal of telecommunication of gathering can be as reference signal to can promote the wearable equipment of wrist formula and detect the accuracy nature of user's heart electrograph. Specifically, first upper limb electrical information and second upper limb electrical information may be determined based on the first signal, the second electrical signal, and the third electrical signal, and below-the-heart body electrical information may be determined based on the first electrical signal and the fourth electrical signal. When the first upper limb electric information and the second upper limb electric information are determined according to the first signal, the second electric signal and the third electric signal, the modes for determining the first upper limb electric information and the second upper limb electric information are different in different wearing modes.
In a first possible implementation, as shown in fig. 8, the wrist wearable device is worn on a first upper limb of the user, and the first electrode and the second electrode are in contact with the first upper limb. The second upper limb presses the third electrode, the third electrode is contacted with the second upper limb,and bringing the fourth electrode into contact with the body below the heart of the user. Thus, the first electrical signal V acquired by the first electrode1For reference, a second electrical signal V is acquired by a second electrode2For measuring the electrical signal obtained at the first upper limb of the user, a third electrical signal V is acquired at a third electrode3A fourth electrical signal V acquired by a fourth electrode for measuring an electrical signal obtained at a second upper limb of the user4To measure electrical signals obtained from the body of the user below the heart. Thus, the control circuit is based on the first electric signal V1And a second electrical signal V2Calculating to obtain first upper limb electrical information VaE.g. Va＝V1–V 22; according to a first electric signal V1And a third electrical signal V3Calculating to obtain second upper limb electrical information VbE.g. Vb＝V1+V 32; according to a first electric signal V1And a fourth electrical signal V4Calculating to obtain the body electrical information V below the heartcE.g. Vc＝V1–V4/2。
In a second possible implementation, the wrist wearable device is worn on a second upper limb of the user, and the first electrode and the second electrode are in contact with the second upper limb. The first upper limb presses the third electrode, which is in contact with the first upper limb and brings the fourth electrode into contact with the body of the user below the heart. Thus, the first electrical signal V acquired by the first electrode1For reference, a second electrical signal V is acquired by a second electrode2A third electrical signal V acquired by a third electrode for measuring an electrical signal obtained at a second upper limb of the user3A fourth electrical signal V acquired by a fourth electrode for measuring the electrical signal obtained by the first upper limb of the user4To measure the electrical signals obtained from the body of the user below the heart. Thus, the control circuit is based on the first electric signal V1And a third electrical signal V3Calculating to obtain first upper limb electrical information VaIs, for example, Va＝V1–V 32; according to a first electric signal V1And a second electrical signal V2Calculating second upper limb electrical information VbIs, for example, Vb＝V1+V 22; according to a first electric signal V1And a fourth electrical signal V4Calculating to obtain the body electrical information V below the heartcE.g. Vc＝V1–V4/2。
Wherein, the first upper limb and the second upper limb are respectively a left limb and a right limb of the user, and when the first upper limb is the left limb, the second upper limb is the right limb; when the first upper limb is a right limb, the second upper limb is a left limb.
It is understood that, as mentioned above, the user may wear the wrist wearable device on the first upper limb or the second upper limb, and the calculation method of the first upper limb information and the second upper limb information by the control circuit may be different in different wearing positions. Therefore, before the control circuit executes S102, the wearing position of the wrist wearable device may also be determined, and the wearing position may be the first upper limb or the second upper limb.
In one possible implementation manner, for example, the wrist wearable device includes a touch screen or a button, the control circuit 140 may prompt the user to make a selection through a display of the wrist wearable device, and the user selects the current wearing position of the wrist wearable device through the touch screen or the button according to the prompt of the display interface, so that the control circuit 140 may determine the wearing position according to the operation of the user. Or, the user can select the wearing position through the external device, and the external device sends the wearing position to the wrist wearable device, so that the wearing position can be determined by the wrist wearable device.
In another possible implementation, the wrist wearable device may include a motion detection apparatus that may acquire motion data of an upper limb wearing the wrist wearable device. The detection device can be a gyroscope or an acceleration sensor, and the corresponding motion data can be motion direction data or motion acceleration data or other data reflecting the motion state of the wrist wearable device. It can be understood that, different characteristics exist when the left limb and the right limb of the human body move, and corresponding movement data can be different, for example, the acceleration directions of the swing arm or the wrist lifting are different. Based on this, the control circuit can judge the wearing position of the current wrist wearable device according to the motion data acquired by the motion detection device so as to determine the calculation mode for calculating the first upper limb electric information and the second upper limb electric information. Specifically, the acquired motion data may be matched with preset motion data by presetting motion data reflecting motion characteristics of the left limb or/and the right limb, so as to determine whether the wearing position of the wrist wearable device is the left limb or the right limb.
For example, in a specific embodiment, the control circuit may compare the motion data with preset first motion data to determine a current wearing position of the wrist wearable device. The first movement data may be set according to movement data of the first upper limb. When the movement data are matched with the preset first movement data, determining that the wearing position of the wrist wearable device is the first upper limb, and calculating the first upper limb electrical information and the second upper limb electrical information according to the first possible implementation mode. And when the movement data are not matched with the preset first movement data, determining that the wearing position of the wrist wearable device is the second upper limb, and calculating the first upper limb electrical information and the second upper limb electrical information according to the second possible implementation mode.
During specific implementation, for the detection of the wearing position, the control circuit can execute after receiving the heart state monitoring instruction, namely the control circuit obtains the motion data after receiving the heart state monitoring instruction, and judges the wearing position of the current wrist wearable device according to the motion data so as to determine the calculation mode for calculating the first upper limb electric information and the second upper limb electric information. The wearing position of the wrist wearable device can also be determined before receiving the monitoring instruction, for example, the user also performs other detection operations before carrying out heart monitoring, and the wearing position is determined in the operation process.
Through wearing position detection, the control circuit can automatically identify whether the wrist wearable device is worn on the left upper limb or the right upper limb so as to determine a method for specifically determining the first upper limb electric information and the second upper limb electric information, thereby acquiring a correct electrocardiogram waveform. According to the scheme, the wrist type wearable equipment does not need to be replaced to an arm on one side, and manual setting operation is not needed. On one hand, the measuring process can be simplified, and the heart state can be measured conveniently and timely by a user. On the other hand, the method is also favorable for avoiding the problem of wrong measured data caused by the fact that the user forgets to replace the arm wearing the wrist wearable device or the operation is set to be wrong, so that the accuracy of the data obtained by the wrist wearable device is improved.
Of course, in addition to the above implementation method for automatically detecting the wearing position, the user may also be instructed to wear the device to the corresponding position during monitoring, and the wearing position may not be determined, and the detection may be directly performed according to a detection manner (e.g., the first possible implementation manner) of the preset position.
And S103, generating an electrocardiogram waveform with at least six leads according to the first upper limb electrical information, the second upper limb electrical information and the body electrical information below the heart.
The control circuit can determine the first upper limb electric information V according to the step S102aSecond upper limb electrical information VbAnd body electrical information V below the heartcCalculating to obtain I-lead electrocardiogram waveform VIComprises the following steps: vI＝Va-Vb(ii) a II-lead electrocardiogram waveform VIIComprises the following steps: vII＝Vc-Vb(ii) a III-lead electrocardiogram waveform VIIIComprises the following steps: vIII＝Vc-Va(ii) a IV lead electrocardiogram waveform VIVComprises the following steps: vIV＝(VI-VII) 2; v-lead electrocardiogram waveform VVComprises the following steps: vV＝VI-V II2; VI-lead electrocardiogram waveform VVIComprises the following steps: vVI＝VII-VI/2. Therefore, in the embodiment of the application, four electrodes are arranged, wherein one electrode is used as a reference electrode, and the other three electrodes are used for measuring the electrical signals of the left limb, the right limb and the body below the heart respectively, so that the six-lead electrocardiogram waveform can be calculated, the heart state can be judged from many aspects, and the abnormal condition of the heart can be found in time.
After generating the electrocardiogram waveforms of at least six leads, the electrocardiogram waveforms may be output through a display of the wrist wearable device, may also be output through a display of an external device connected to the wrist wearable device, and may also be uploaded to the cloud server through the wireless communication module. Here, the external device connected to the wrist wearable device may be an electronic device connected by a wired or wireless manner.
