Description

How to get ECG data

The present invention relates to a method, especially a method for obtaining data, especially a method for obtaining electrocardiogram data by using a portable ECG signal detector.

According to the American Heart Association, the average person's heart beats about 100,000 times a day. If a person's heart beats much faster or slower than this, or if the rate is irregular, the person may have arrhythmia (Arrhythmia). Symptoms caused by arrhythmia can cause dizziness in mild cases, and death in severe cases. Therefore, heart rhythm monitoring and timely diagnosis and treatment are the most effective means to prevent arrhythmia from posing health threats. At the same time, it can also monitor and prevent other heart-related diseases, such as myocardial hypoxia and ventricular hypertrophy.

The best way to monitor heart rhythm is to have the patient lie still in bed for resting ECG monitoring. However, conditions such as cardiac arrhythmia or lack of oxygen to the heart may not necessarily be present at the time the patient is being tested. In order to grasp these changes that take place at any time, there is a device for having an electrocardiogram monitoring instrument on the body throughout the day to obtain a dynamic electrocardiogram. The mature and commonly used Holter monitor is the Holter Monitor. Patients can wear a portable electronic recorder on the chest, and the electronic recorder can obtain heart rhythm data through several electrodes installed on the chest skin. The Hult monitor can continue to operate 24 hours a day, and only after recording data for more than two weeks will it transmit all data to medical institutions for subsequent analysis and processing. In addition, common similar devices include mobile cardiac telemetry (Mobile Cardiac Telemetry, MCT) monitors. This device is more convenient to use than the Hult monitor, because it can automatically transmit the ECG data without the need for the patient to participate in the operation.

When these existing heart rhythm monitors are connected to a management host, such as a server of a hospital's medical information system, monitoring data is usually uploaded via a network through an independent transmission device. For wireless transmission devices, data transmission is limited by environmental noise. If the environmental noise is too large, the transmitted data will be lost, which is very unfavorable for the follow-up processing procedures to analyze the patient's condition with complete data.

In order to solve the aforementioned problem of data omission, the present invention proposes an innovative method for obtaining electrocardiogram data.

In the method for obtaining electrocardiogram data mentioned above, the temporarily stored first part or the second part of the ECG signal can be sent to the computing system, or it can be checked whether the ECG signal received by the computing system is complete, if it is not complete, Then request the temporarily stored first part or second part of ECG signals to be transmitted to the computing system through the relay device, so as to ensure that the computing system has all the ECG signals.

Preferably, the transmission or temporary storage of the ECG signal is performed by the portable ECG signal detector judging whether it has received a request or a feedback message from the relay device.

In order to achieve the purpose of the present invention, the hardware of these three technical components must be specific, and must cooperate with related software control.

In the hardware structure of FIG. 2 , the portable ECG detector 10 is an integrated and partially disposable ECG detection device. The portable ECG signal detector 10 is attached to the skin of the chest cavity of a human body to continuously detect ECG signals. Furthermore, the portable ECG detector 10 collects the potential changes of the human skin near the heart due to the heartbeat, digitizes these continuous potential values, modulates them into wireless signals and transmits them to the computing system 30 for calculation The system 30 can restore the actual heartbeat condition of the subject, and then analyze the health problems of the subject. Compared with traditional Hult monitors and monitors, in addition to the same detection principle, the portable ECG detector 10 has different features in consideration of reusability, non-pollution and continuous wireless transmission of data. Improve. Please refer to FIG. 4 , which is a cross-sectional view of the portable ECG signal detector 10 . Portable The ECG signal detector 10 includes a body 11 , a disposable installation device 12 and an ECG signal detection device 13 . The main body 11 is a protection device, which has a cavity 111 in which the ECG signal detection device 13 for processing detected ECG signals is placed and protected. The disposable installation device 12 is attached to the skin of the chest cavity of the human body once, directly obtains the potential change of the human skin, and can be discarded after a period of use. The disposable installation device 12 includes a flexible circuit board 121 , at least one sticker 122 and at least two electrodes 123 . The flexible circuit board 121 contains several circuits (not shown), connects the electrodes 123 and the ECG signal detection device 13, and at least one attachment device 122 is installed on one side of the main body 11 for detachable attachment to the human body Chest skin. In practice, the applicator 122 can be a suction cup or an adhesive tape, which can detachably adhere the body 11 , the ECG signal detection device 13 , the flexible circuit 121 and the electrodes 123 to the skin of the chest cavity of a human body. When the subject of the portable ECG signal detector 10 is to be replaced, or when the portable ECG signal detector 10 falls due to sweating or skin shedding of the same subject , the disposable installation device 12 can be separated from the main body 11 and the ECG signal detection device 13, and can be updated separately. At this point, the portable ECG signal detector 10 can be restored to the use state. In this embodiment, there are two electrodes 123 . In practice, the number of electrodes 123 can be more, such as four. The electrodes 123 and the at least one sticker 122 are installed on the same side of the main body 11, and the electrodes 123 are connected to the main body 11 through a connection circuit (via the flexible circuit board 121), and communicate with the ECG signal detection device 13. connection number.

The electrocardiogram detection device 13 is detachably installed in the cavity 111 and is a special electronic product. Regarding the hardware structure of the ECG signal detection device 13 , please refer to FIG. 5 , which is a block diagram of components of the ECG signal detection device 13 . For the convenience of description, in FIG. 5 , signal connections between components are shown by dotted lines, and electrical connections between components are shown by solid lines. The ECG signal detection device 13 includes a storage unit 131 , a wireless transmission unit 132 , a processor 133 , an input unit 134 and a power unit 135 . The storage unit 131 includes a random access memory and a solid-state chip storage device, which can store ECG signals and program codes of software running on the processor 133 . The wireless transmission unit 132 can be configured to connect with the gateway 20 through wireless signals, and can be a Bluetooth communication module or a Wi-Fi module in practice. Through the gateway 20, the wireless transmission unit 132 can detect the ECG signal The ECG signals preliminarily processed by the device 13 are sent to the computing system 30 in batches. The processor 133 is electrically connected to the at least two electrodes 123 through a connection circuit, and can convert the potential change from the at least two electrodes 123 into an electrocardiographic signal, and transmit the electrocardiographic signal through the wireless transmission unit 132 to the Gateway 20.

In practice, the power unit 135 can be a disposable mercury battery or a rechargeable and reusable lithium battery.

In addition to the portable ECG detector 10, the gateway 20 is also a special electronic product. Generally speaking, a gateway is a device that connects two or more individual networks (such as a home network and the Internet), and can determine the path for data packet transmission. In addition to the above basic functions, the gateway 20 of the present invention also needs to have the function of temporarily storing data and uploading the stored data under specific circumstances. To this end, a block diagram of components of a typical gateway 20 is shown in FIG. 6 . The gateway 20 includes an antenna module 21 , a receiving signal processing circuit 22 , a sending signal processing circuit 23 , a processing module 24 and a storage module 25 . The antenna module 21 is a tool for receiving or emitting electromagnetic waves of specific frequency bands. After the received external electromagnetic wave is demodulated by the receiving signal processing circuit 22 electrically connected to the antenna module 21 , the signal carried therein will be sent to the processing module 24 electrically connected to the receiving signal processing circuit 22 . The processing module 24 transmits the data of the packet to another destination in the network according to the instruction of the packet in the received signal. Therefore, the processing module 24 will pass the repackaged packet to the transmission signal processing circuit 23 connected to the electric signal, and the transmission signal processing circuit 23 will modulate the packet into the transmission signal, and finally the antenna module 21 converts the packet into an electromagnetic wave to send outside launch. According to the present invention, if there is an ECG signal in the packet, the processing module 24 can temporarily store the ECG signal in the storage module 25 without receiving notification from the receiving end (computing system 30), so as to facilitate setting resend in case. The details of the settings for these transmissions will be described later. The computing system 30 is at least one server, which is specially used to analyze the ECG signals from the subject. The work of the computing system 30 includes, but is not limited to receiving Receive ECG signals, reconstruct ECG signals according to time sequence, analyze ECG signals and infer abnormal heart rhythm, and report to gateway 20 or portable ECG signal detection when missing ECG signals occur. The device 10 requires a retransmission.

It should be noted that FIG. 2 is one of many hardware architectures for implementing the method for obtaining ECG data. The gateway 20 is designed to be mounted on the subject's clothing (eg waist), connected to the network 50 through the IP sharer 40 , and then connected to the computing system 30 by signal. In recent years, due to the improvement of mobile communication technology, many smart phones also have routing functions. Therefore, the gateway 20 applied to the present invention can also be a smart phone. Please refer to FIG. 3 , which shows another hardware structure for implementing the method for obtaining ECG data. The smart phone 20a replaces the gateway 20 and the IP sharer 40 in FIG. 2 , and can be directly connected to the computing system 30 via the mobile communication network 51 . In practice, the present invention is not limited to the physical form of the relay device, but focuses on the hardware having the functions detailed in the specification.

Please refer to Fig. 1 again, a method for obtaining electrocardiogram data includes the following steps. The first step is to attach a portable ECG signal detector 10 to the skin of the chest cavity of a human body to continuously detect ECG signals (S01). The function and operation method of the portable ECG signal detector 10 are described as above, and will not be repeated. The second step is to wirelessly connect the portable ECG detector 10 with a relay device (gateway 20) (S02). This step is to connect the two devices to ensure that the signals can be transmitted to each other.

The third step is to transmit the detected ECG signals to the gateway 20 for storage, wherein if a certain part of the ECG signals cannot be received by the relay device (gateway 20), then the part of the ECG signals Temporarily stored in the portable ECG detector 10 (S03). For a better understanding of this step, please refer to FIG. 7 , which shows an operation example in the first embodiment. The time starts from T0, and the portable ECG signal detector 10 continues to detect the ECG signals, and sends them to the computing system 30 in segments. The portable ECG detector 10 can set a period of time (the time between T0 and T1, such as 5 minutes) to send the accumulated detected ECG signals to the gateway 20 for temporary storage. The gateway 20 confirms receiving the first ECG signal from the portable ECG signal detector 10 at T2, and sends a feedback notification to the portable ECG signal detector 10 confirming the receipt of the first ECG signal. The ECG signal detector 10 simultaneously stores the first ECG signal. The portable ECG signal detector 10 continuously detects ECG signals from T1 to T3 and obtains a second ECG signal. According to the setting, the portable ECG signal detector 10 falls within a preset time after T1 (including the time for completing the transmission of the first ECG signal and waiting for the reply of the gateway 20, falling between T2 and T3), expecting The feedback notification was received. Because of receiving the feedback notification, the portable ECG detector 10 will transmit the second ECG signal to the gateway 20 at the time point T3 set after T1. Similarly, the gateway 20 confirms receiving the second ECG signal from the portable ECG signal detector 10 at T4, and sends a feedback notification to the portable ECG signal detector 10 confirming receipt of the second ECG signal The detector 10 stores the second ECG signal at the same time. However, at T5, the portable ECG detector 10 sends the third ECG signal to the gateway 20 to detect the third ECG signal between T3 and T5, but the gateway 20 misses it due to poor communication environment. Therefore, the portable ECG detector 10 cannot receive the feedback notification from the gateway 20 within the preset time. According to the present invention, the portable ECG signal detector 10 temporarily stores the third ECG signal at T6, but continues to detect and obtain the fourth ECG signal from T5 to T7. When the time comes to T7, the portable ECG detector 10 transmits the fourth ECG signal to the gateway 20, and at the same time ends the detection operation. The gateway 20 confirms receiving the fourth ECG signal from the portable ECG signal detector 10 at T8, and sends a feedback notification confirming the receipt of the fourth ECG signal to the portable ECG signal detector 10. Simultaneously store the fourth ECG. Preferably, the ECG signal stored in the gateway 20 can be transmitted to the computing system 30 synchronously, or can be transmitted by triggering the gateway 20 . On the other hand, the transmission or temporary storage of ECG signals is carried out by the portable ECG signal detector 10 judging whether a request or a feedback message from the relay device (gateway 20) is received. The request or feedback message from the gateway 20 executes the transmission action, and if the request or feedback message from the gateway 20 is not received within a specified time, the temporary storage action is executed. In addition, the request or feedback message is continuously and actively generated by the relay device at a specific frequency.

Next, the fourth step of the first embodiment of the method for obtaining electrocardiogram data is to transmit the ECG signal stored by the relay device (gateway 20) to a computer connected to the relay device (gateway 20) with wireless signals. System 30 (S04). In FIG. 7, since the portable ECG detector 10 has already After the detection operation is finished, the gateway 20 then transmits its stored data (the first ECG, the second ECG and the fourth ECG) to the computing system 30 . Therefore, according to the setting, the gateway 20 transmits the first ECG signal, the second ECG signal and the fourth ECG signal to the computing system 30 at the time point T9 (the time period from T8 to T9 is not limited). If the ECG signal is not missed, then the first embodiment can proceed to the final step: the computing system 30 reorganizes and analyzes the received ECG signal according to time sequence and infers abnormal heart rhythm ( S05 ). Obviously, the computing system 30 missed the third ECG signal. In order to supplement the missing data in the computing system 30, there are two processing methods between step S04 and step S05.

The first processing method is to transmit the ECG signals temporarily stored in the portable ECG signal detector 10 to the computing system 30 . Please see Fig. 7 again, according to the setting, the portable ECG signal detector 10 retransmits the third ECG signal stored by itself to the gateway 20 at the time point T10 (the time between T9 and T10 is not limited). , so that the gateway 20 relays the third ECG signal to the computing system 30 . Similarly, the gateway 20 confirms receiving the retransmitted third ECG signal from the portable ECG signal detector 10 at T11, and sends a feedback notification confirming receipt of the retransmitted third ECG signal to A portable ECG detector 10 . At this time, the gateway 20 does not store the third ECG signal at the same time, but directly sends the third ECG signal to the computing system 30 again. The above processing method is automatically performed by the portable ECG signal detector 10 .

Regarding the second processing method, please refer to FIG. 8 , which shows another operation example in the first embodiment. The events at T0 to T9 in FIG. 8 are the same as those in FIG. 7 . According to the present invention, the second processing method is to check whether the ECG signal received by the computing system 30 is complete, and if it is incomplete, request the portable ECG signal detector 10 through the gateway 20 to temporarily store the ECG signal The ECG signal is sent to the computing system 30 through the gateway 20 again. Checking whether the ECG signal received by the computing system 30 is complete is based on whether there is a discontinuous interruption in the time series of the ECG signal. As shown in Figure 8, according to the setting, the computing system 30 sorts out the data at the time point T10' (the time between T9 and T10' is not limited), and finds that the third ECG signal is missing in time series, and the received ECG There are discontinuous interruptions in electrical signals. Therefore, the computing system 30 requests the portable ECG detector 10 through the gateway 20 at the time point T11' (which can be set according to the actual situation) to transfer the temporarily stored ECG The number is transmitted to the computing system 30 through the gateway 20 again. Upon receiving the request, the portable ECG detector 10 retransmits the third ECG signal to the gateway 20 at T12'. The gateway 20 confirms the receipt of the retransmitted third ECG signal from the portable ECG signal detector 10 at T13', and sends a feedback notification confirming the receipt of the retransmitted third ECG signal to the portable The type ECG detector 10 transmits the retransmitted third ECG signal to the computing system 30 at the same time. The above processing method is initiated by the computing system 30 and carried out by the portable ECG detector 10 .

According to the present invention, the transmission of the ECG signal can be continuously sent by the relay device (gateway 20) in addition to being actively sent by the portable ECG signal detector 10 to the relay device (gateway 20). The request message is used to notify the portable ECG signal detector 10 to transmit the ECG signal. For example, before T1, the gateway 20 can actively send a request message to the portable ECG detector 10, so that the portable ECG detector 10 can transmit the first ECG signal at T1. To the gateway 20; the gateway 20 confirms receiving the ECG signal from the portable ECG detector 10 at T2, T4, T6 and sends a confirmation feedback notification to the portable ECG detector 10 Afterwards, a request message is sent to the portable ECG detector 10, so that the portable ECG detector 10 continues to send subsequent ECG signals. When the portable ECG signal detector 10 receives the request message, it will send the corresponding ECG signal to the gateway 20, if it does not receive it, it will not send it. When the portable ECG signal detector 10 If the request message is not received within a certain time period, the ECG signal is stored.

In the above first embodiment, the ECG signals missed during the transmission are backed up and stored in the portable ECG signal detector 10 . However, according to the present invention, the missed ECG signals can be stored in the portable ECG signal detector 10 and the gateway 20 respectively according to the location of occurrence. This technique is described below with a second embodiment.

Please refer to FIG. 9 , which is a flow chart of the second embodiment of the method for obtaining ECG data according to the present invention. In this embodiment, the method for obtaining ECG data includes the following steps. The first step is to attach a portable ECG signal detector 10 to the skin of the chest cavity of a human body to continuously detect ECG signals (S11). The content and purpose of this step are the same as the step S01 of the previous embodiment, and will not be described repeatedly. second step The step is to wirelessly connect the portable ECG detector 10 with a relay device (gateway 20) (S12), and this step is also the same as step S02.

The third step is to transmit the detected ECG signal to the relay device (gateway device 20) for storage, wherein if a first part of the ECG signal cannot be received by the relay device (gateway device 20), the The first part of the ECG signal is temporarily stored in the portable ECG signal detector 10 (S13). For a better understanding of this step, please refer to FIG. 10 , which shows an operation example in the second embodiment. The events from T0 to T9 in FIG. 10 are the same as those in FIG. 7, that is, the portable ECG signal detector 10 successfully resends the first, second and fourth ECG signals and stores them in the gateway. 20 in. The third ECG signal cannot be received by the gateway 20 due to an error, and thus is temporarily stored in the portable ECG signal detector 10 . Here, the first part of the ECG signal refers to the third ECG signal.

The fourth step of the second embodiment of the method for obtaining ECG data is to transmit the ECG signal received by the relay device (gateway 20) to a computer connected to the relay device (gateway 20) with wireless signals. If a second part of the ECG signal cannot be received by the computing system 30, the second part of the ECG signal is temporarily stored in the relay device (gateway 20) (S14). In Figure 10. At T10, the computing system 30 notifies the gateway 20 to confirm the receipt of the first and fourth ECG signals. The signal is the aforementioned second part of the ECG signal. Same as the previous embodiment, the ECG signal temporary storage operation is performed by the portable ECG signal detector 10 judging whether it receives a request or a feedback message from the relay device (gateway 20 ). If the ECG signal is not missed, then the second embodiment can proceed to the final step: the computing system 30 reorganizes, analyzes and infers the abnormality of the heart rhythm from the received ECG signal according to time sequence ( S15 ). However, since the portable ECG detector 10 has stopped the detection operation and the computing system 30 has missed the second and third ECG signals from the portable ECG detector 10, it is necessary to make up ECG signals missed by the system 30 are calculated. Similarly, there are two processing methods between step S14 and step S15.

The first processing method is to transmit the temporarily stored first part or second part of the ECG signal to the computing system 30 . Please refer to FIG. 10 again. According to the setting, the portable ECG signal detector 10 retransmits the third ECG signal stored by itself to the gateway 20 at the time point T11 (the time between T10 and T11 is not limited). After receiving the third ECG signal, the gateway 20 replies at T12 to confirm the receipt of the third ECG signal, and relays the third ECG signal to the computing system 30 . At this moment, the gateway 20 does not store the third ECG signal. After receiving the third ECG signal, the computing system 30 replies to the gateway 20 to confirm receiving the third ECG signal at T13. Then, it is the turn of the gateway 20 to retransmit the stored fourth ECG signal to the computing system 30 at T14, until the time point T15 receives a reply from the computing system 30 confirming the receipt of the fourth ECG signal, All work is over. According to the present invention, the gateway 20 can also retransmit the temporarily stored ECG signal to the computing system 30 before the portable ECG signal detector 10 . The above processing methods are actively performed by the portable ECG signal detector 10 and the gateway 20 .

Regarding the second processing method, please refer to FIG. 11 , which shows another operation example in the second embodiment. The events at T0 to T10 in FIG. 8 are the same as those in FIG. 10 . According to the present invention, the second processing method is to check whether the ECG signal received by the computing system 30 is complete, and if it is incomplete, request the temporarily stored first or second part of the ECG signal to pass through the gateway 20 to the computing system 30. Similarly, checking whether the ECG signal received by the computing system 30 is complete is based on whether there is a discontinuous interruption in the time series of the ECG signal. As shown in Figure 11, according to the setting, the computing system 30 organizes the data at the time point T11' (the time between T10 and T11' is not limited), and finds that the third ECG and the fourth ECG are missing in time series No., the received ECG signal has discontinuous interruption. Therefore, the computing system 30 requests the portable ECG detector 10 to transmit the temporarily stored third ECG signal to the computing system 30 again through the gateway 20 at the time point T11'. Upon receiving the request, the portable ECG detector 10 retransmits the third ECG signal to the gateway 20 at T12'. The gateway 20 confirms the receipt of the retransmitted third ECG signal from the portable ECG signal detector 10 at T13', and sends a feedback notification to the portable The type ECG detector 10 transmits the retransmitted third ECG signal to the computing system 30 at the same time. Computing system 30 is received the 3rd electrocardiogram signal, at T14 ' send the reply that confirms to receive the 3rd electrocardiogram signal Cover the gateway 20. Then, the computing system 30 requests the gateway 20 to retransmit the fourth ECG signal to the computing system 30 at T15'. The gateway 20 retransmits the fourth ECG signal at T16', and receives a reply from the computing system 30 confirming receipt of the fourth ECG signal at T17', and all operations are completed. Similarly, the request for retransmitting the ECG signal can also be sent to the gateway 20 first, and then the request for retransmitting the ECG signal is sent to the portable ECG detector 10 (through the gateway 20). The above processing method is initiated by the computing system 30 , and the portable ECG signal detector 10 and the gateway 20 cooperate for it.

In the foregoing embodiments, there is a point that needs attention. When the portable ECG detector 10 and the gateway 20 work, it is preferable to keep the distance within 10 meters. To avoid the problem of signal loss. After all, retransmitting ECG signals takes time and power, which is not a good thing.
