Description

Electrocardiogram measuring device and method {apparatus and method of electrocardiogram}

This technology relates to a method for an electrocardiogram measuring device to measure an electrocardiogram.

Recently, it is possible to conveniently diagnose a patient's heart condition through an electrocardiogram (ECG) device. The presence or absence of heart abnormalities can be confirmed through electrocardiogram measurement, and it is a basic indicator considered for diagnosing cardiovascular diseases such as arrhythmia, cardiomyopathy, valvular disease, and heart failure.

Among various electrocardiogram measurement devices, hospital electrocardiogram devices use a 12-channel electrocardiograph using 10 wet electrodes as standard. Hospital electrocardiogram devices can measure detailed heart conditions, but they can only be used when the user visits a hospital. Additionally, the user feels uncomfortable during the measurement process due to the use of a large number of electrodes. For this reason, a simplified electrocardiogram measurement device is sometimes used. A simplified ECG measurement device can measure the ECG using fewer electrodes than a hospital ECG device. Specifically, the simplified ECG measurement device can conveniently measure the ECG using only 6 channels with 3 electrodes or 8 channels with 4 electrodes.

However, although the conventional simplified ECG measurement device reduces the discomfort felt by the user during the measurement process, there is a problem in that the measurement results are relatively less accurate than hospital ECG devices.

Accordingly, there is an increasing demand for an ECG measurement device that simply measures the ECG using a simplified ECG measurement device and produces more accurate results than existing simplified ECG measurement devices.

The housing 10 forms an internal space that accommodates various components. The housing 10 may be formed in a dumbbell shape. The internal space formed by the housing 10 may have an open top. The upper part of the internal space may be covered by a display to be described later. The first electrode 200 and the second electrode 300 may be connected to the front of the housing 10. A third electrode 400 may be connected to the rear of the housing 10. In some cases, the first to third electrodes 200 to 400 may be part of the housing 10 or may be formed to be inserted into the housing 10.

The housing 10 includes an external input unit 20. The external input unit 20 is formed outside the housing 10. The external input unit 20 may be formed in the form of a receiver or port inserted into the housing 10. The first external electrode unit 500, which is formed separately from the housing 10, may be coupled to the housing 10 through the external input unit 20. When the external input unit 20 is a port, the housing 10 and the first external electrode unit 500 may be connected with a wired cable. Specifically, the external input unit 20 may be formed of a USB port, 3.5 pie terminal, DC port, etc.

On the other hand, when the external input unit 20 is a receiver, the housing 10 and the first external electrode unit 500 can be wirelessly coupled. Through the combination of the external input unit 20 and the first external electrode unit 500, a potential signal measured in a device formed separately from the housing 10 can be received.

Although not shown in FIG. 1, the housing 10 may include a display and a control unit. Specifically, the display may be coupled to the front of the housing 10. The display is formed in a plate shape and is the part that comes into contact with the sensing object. Through the display, options according to the electrocardiogram measurement method, which will be described later, can be output. The display may include a circuit structure and a chipset that can detect the touch of the sensed object. The specific structure of this circuit structure and chipset may be determined by a capacitive method, a pressure-sensitive method, etc., but since this corresponds to a structure already known in the related art, a detailed description will be omitted.

The communication unit may be located in the internal space of the housing 10. The communication unit is formed of a chipset and can communicate with external devices. Specifically, through the communication unit, information on at least one of the first to third options to be described later can be transmitted to a separate external device that is separate from the electrocardiogram measuring device, and the measured potential signal can be transmitted and received.

The control unit is present inside the housing 10. The control unit may calculate electrocardiogram measurement results through the potential signals of the subject being measured that are input from the first electrode 200 to the third electrode 400 and the first external electrode 520 unit 500. Additionally, the electrocardiogram measurement method, which will be described later, can be controlled through the control unit.

The display of the electrocardiogram measuring device of the present invention can detect actions such as the position, movement, or pressing of the sensed object. Therefore, when the sensed object selects a given option, the received information is transmitted to the control unit, and the control unit operates the ECG measurement device in a single mode based on the received input information.

The first electrode 200 to the third electrode 400 are coupled to the housing 10. The first electrode 200 to the third electrode 400 may be at least one of a dry electrode or a wet electrode. As in the embodiment of FIG. 1, the first electrode 200 to the third electrode 400 may be formed as part of the housing 10. When formed as part of the housing 10, the electrocardiogram sensing device can receive a potential signal by directly contacting the first electrode 200 to the third electrode with the body part of the subject without a separate cable. The first electrode 200 to the third electrode 400 may be inserted into the housing 10 .

When the first connection part 510 of the first external electrode part 500, which will be described later, is coupled to the external input part 20 formed in the housing 10, the potential signal received by the third electrode 400 is connected to the first external electrode. The first external electrode 520 of the unit 500 may be replaced with an input potential signal. When the role of the third electrode 400 is replaced by the first external electrode unit 500, the third electrode 400 is deactivated, and by deactivating the third electrode 400, noise is generated in the process of receiving the potential signal. can be suppressed, malfunctions can be prevented, and unnecessary power consumption can be prevented. Additionally, the third electrode 400 may be inserted into the interior of the housing 10 in the deactivation step.

In another embodiment, the first electrode 200 to the third electrode 400 may include a cable extending from the housing 10. In the case of a type including a cable, the person being measured can directly attach the first electrode 200 to the third electrode 400 to the body part where the potential signal is to be measured so that the ECG sensing device can receive the potential signal. The electrocardiogram measuring device of the present invention is not limited to the combination of electrodes described above.

The electrocardiogram measuring device can receive a potential signal according to the heartbeat of the subject by contacting, adhering to, or attaching the above-mentioned electrodes to the body of the subject. Electrocardiogram measurement results can be calculated through the input potential signal. In order to calculate electrocardiogram measurement results, a potential difference input signal received from at least two or more electrodes is required.

The first external electrode unit 500 includes a first external electrode 520 and a first connection part 510. The first external electrode unit 500 is formed separately from the housing 10. The first external electrode 520 of the first external electrode unit 500 is formed in the form of at least one of clips, a band, a patch, and a strap. Accordingly, the first external electrode can receive a potential signal from one of the limbs. For example, if you want to measure electric potential signals from one of the limbs, it can be formed in the form of a pincer or strap.

In this way, depending on which part of the limb receives the potential signal, the first external electrode is formed in an appropriate one of the above-described forms. The first connection part 510 is connected to the first external electrode 520 and includes a cable. A portion of the extreme end of the first connection portion 510 is formed in a shape corresponding to the external input portion 20. Specifically, when the external input unit 20 is a port, it is formed in the same shape as the corresponding insertion unit. Specifically, it can be formed with a USB socket, 3.5 pi jack, DC connector, etc. On the other hand, when the external input unit 20 is in the form of a receiver, it is formed in the same form as the corresponding antenna sensor.

Hereinafter, an embodiment of the present invention will be described with reference to FIG. 2.

Figure 2 is a diagram for explaining an embodiment of the electrocardiogram measurement method according to the present invention.

In step S210, the ECG measurement device determines whether the first external electrode unit 500 is coupled to the external input unit 20. Specifically, the electrocardiogram measuring device determines whether the first connection portion 510 of the first external electrode portion 500 is coupled to the external input portion 20 formed in the housing 10. When the external input unit 20 is formed as a port, it is determined whether the first connection unit 510 is coupled physically or electrically. As a physical method, the number of port pins can be changed or a physical switch can be inserted into the ECG measurement device. By electrical method, current can be passed when the first connection part 510 is coupled to the port. When the external input unit 20 is connected wirelessly, pairing can be determined. As described above, signals can be received differently depending on whether the first external electrode unit 500 is coupled or not and the type of connection. Therefore, by the external input unit 20 of the ECG measuring device generating an additional signal depending on whether the first external electrode unit is coupled, the ECG measuring device determines whether the first external electrode unit 500 is coupled or not and whether the first external electrode unit 500 ) can be determined. The electrocardiogram measurement method of the present invention is not limited to the type of determination of whether the electrodes are coupled or not described above.

When step S210 is completed, the next step, step S221 or step S222, is performed.

In step S221, if it is determined that the first external electrode unit 500 is coupled to the external input unit 20, at least one measurement mode that can measure the electrocardiogram using the first external electrode 520 is included. Provides the first option. The first option using the first external electrode unit 500 may provide various image options depending on the use of the first external electrode unit 500.

For example, at least one of the images provided by the first option disables the third electrode 400 and utilizes only the first electrode 200, the second electrode 300, and the first external electrode unit 500. An image measuring the electrocardiogram can be provided as an option. The first option provided by the electrocardiogram measuring device is not only the option of receiving a potential signal using a suitable electrode, but also can guide a desirable posture in a situation where a potential signal is input by using an electrode, such as attaching or pinching an electrode. Specifically, when the first external electrode 520 unit 500 is in the form of a clamp suitable for measuring the potential signal of the leg, the first external electrode 520 unit 500 is used for one leg (left leg or right leg). ), you can receive a potential signal by picking it up.

In addition, in the method of attaching the first electrode 200 and the second electrode 300 to both hands, the preferred attachment position can be guided, and in the method of pinching the legs of the first external electrode unit 500, the preferred attachment position can be guided. It can guide you where to pick it up. The method of providing the first option may be output through a display unit coupled to the electrocardiogram measurement device. In some cases, selection information may be transmitted to a separate external device that is separate from the electrocardiogram measurement device.

In addition to the examples described above, various options may be provided. In the above-described example, it is explained that the third electrode 400 is deactivated and the first external electrode 520 is activated, but the present invention is not limited to this. In some cases, all of the first, second, and third electrodes and the first external electrode 520 may be activated, providing an option to measure the electrocardiogram using four electrodes.

In step S222, if it is determined that the first external electrode unit 500 is not coupled to the external input unit 20, at least one measurement mode that can measure the electrocardiogram without using the first external electrode 520 is selected. Provides a second option included. The second option, which does not use the first external electrode 520 unit 500, may provide various image options depending on the use of the third electrode 400.

For example, at least one of the images provided by the second option is an image measuring the electrocardiogram using only the first electrode 200 and the second electrode 300 without using the third electrode 400. can be provided. The second option provided by the electrocardiogram measuring device is not only the option of receiving a potential signal using a suitable electrode, but it can also guide a desirable posture in a situation where a potential signal is input by using an electrode, such as attaching or holding an electrode. Specifically, when the first electrode 200 to the third electrode 400 of the electrocardiogram measuring device are formed as one piece, hold the first electrode 200 with your left hand and hold the second electrode 300 with your right hand, 3 The electrode 400 is in an inactive state and can provide the option of receiving potential signals from only two locations.

In addition, in the method of holding the first electrode 200 and the second electrode 300 of the above-mentioned options, the preferred holding position of the fingers can be guided. The method of providing the second option may be output through a display unit coupled to the electrocardiogram measurement device. In some cases, selection information may be transmitted to a separate external device that is separate from the electrocardiogram measurement device.

When step S221 or step S222 is completed, the next step, step S230, is performed.

In step S230, selection information regarding the user's selection of one of the first option and the second option is input, and one measurement mode according to the selection information is determined as the motion measurement mode. The ECG measurement device determines a separate single measurement mode according to the user's selection and utilization of the first electrode 200 to the third electrode 400 and the first external electrode 520.

For example, when a choice is provided through a display, the display may be formed in a structure capable of detecting the touch of the sensed object, as described above. In this case, when the user selects one option through touch interaction, the selected option is transmitted to the ECG measurement device and operates in a single measurement mode. As another example, when the display is formed in a structure that cannot detect touch, a control unit with a separate button may be formed in the ECG device. Accordingly, the user selects one option through the control panel and operates in a single measurement mode appropriate for that option.

As another example, when option information is transmitted to a separate external device connected to the ECG device, an option is selected by manipulating the external device, and the ECG device receives the selected option information to determine a single measurement mode. A separate external device may be a smartphone, smart pad, display device, etc. The present invention is not limited to the method of receiving the above-described option information. When step S230 is completed, the next step, step S240, is performed.

In step S240, a potential signal is input through at least one electrode used in the operation measurement mode among the first electrode 200 to the third electrode 400 and the first external electrode 520 unit 500. Receive.

The single measurement mode in which the ECG measurement device operates measures the potential signal using only the necessary electrodes among the first electrodes 200 to 3 electrodes 400 and the first external electrode unit 500 used for measurement according to the selection information. do. By determining a single measurement mode, unused electrodes can be deactivated, thereby preventing unnecessary power consumption and the inflow of external signals generated by unused electrodes. When the measurement mode receives a potential signal, the potential signal can be input from three electrodes or two electrodes.

Additionally, when receiving a potential signal using three electrodes, the potential signal can be received by attaching two electrodes to one area and attaching the other to another area. For example, when receiving a potential signal using three electrodes, attach one electrode to one hand (right hand or left hand) and then attach the other two electrodes to one leg (left leg or right leg). By attaching it, you can receive a potential signal. The present invention is not limited to the number of electrodes receiving potential signals. In the process of determining the measurement mode and receiving the potential signal, if there is an abnormality in the reception state of the potential signal, a warning can be sent to the user through the above-mentioned display or external device.

When step S240 is completed, the next step, step S250, is performed.

In step S250, the potential signal received in the input receiving step is processed by a predetermined signal processing method according to the motion measurement mode to produce an electrocardiogram measurement result. Since the potential signal received by the ECG device is different depending on the selected measurement mode, the ECG measurement result is calculated according to a predetermined signal processing method. Specifically, depending on the selected measurement mode, the input potential signals may be from both arms and left legs, or from the left arm and both legs. Therefore, since the potential signals measured at different parts have different waveforms, the electrocardiogram measurement results are calculated according to a predetermined signal processing method by matching the selected measurement mode and the input potential signal.

When step S250 is completed, the next step, step S260, is performed.

In step S260, electrocardiogram measurement results are provided. The electrocardiogram measurement results calculated by the electrocardiogram device can be transmitted to the display or external device described above and provided to the user. Through the measurement results provided to the user, the user can check whether there is an abnormality in his or her heart. Specifically, prior to diagnosing cardiovascular diseases such as arrhythmia, cardiomyopathy, valvular disease, and heart failure, it is possible to check for abnormalities to determine whether a detailed diagnosis is required in the future.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 3.

Figure 3 shows an electrocardiogram device according to another embodiment of the present invention.

For convenience of explanation, the embodiment described with reference to FIG. 3 will be described focusing on differences from the embodiment described in FIGS. 1 and 2.

In Figure 3, the second external electrode unit 600 is shown. The second external electrode unit 600 is formed separately from the housing 10. The second external electrode unit 600 may be coupled to the housing 10 through the external input unit 20 of the housing 10. As described above, when the external input unit 20 of the housing 10 is a port, the housing 10 and the second external electrode unit 600 may be coupled with a wired cable. On the other hand, when the external input unit 20 is a receiver, the housing 10 and the second external electrode 620 unit 600 can be wirelessly coupled. Through the combination of the external input unit 20 and the second external electrode unit 600, a potential signal measured in a device formed separately from the housing 10 can be received.

The second external electrode unit 600 includes a second external electrode 620 and a second connection part 610. The second external electrode unit 600 is formed separately from the housing 10.

Accordingly, the second external electrode can receive a potential signal from one point in the chest.

For example, if you want to measure a potential signal at a specific point in the chest, it can be shaped like a chest ball or Velcro. In this way, the second external electrode is formed in one of the above-described forms, depending on which point in the chest receives the potential signal. A portion of the extreme end of the second connection portion 610 is formed in a shape corresponding to the external input portion 20. Specifically, when the external input unit 20 is a port, it is formed in the same shape as the corresponding insertion unit. On the other hand, when the external input unit 20 is in the form of a receiver, it is formed in the same form as the corresponding antenna sensor.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 4.

4 , if it is determined in step S410 that the first external electrode unit is not coupled to the external input unit, the next step, step S420, is performed.

In step S420, the ECG measurement device determines whether the second external electrode unit 600 is coupled to the external input unit 20. Specifically, the electrocardiogram measurement device determines whether the second connection portion 610 of the second external electrode 620 portion 600 is coupled to the external input portion 20 formed in the housing 10. When the external input unit 20 is formed as a port, it is determined whether the second connection unit 610 is coupled physically or electrically. As a physical method, the number of port pins can be changed or a physical switch can be inserted into the ECG measurement device. By electrical means, current can be passed when the second connection part 610 is coupled to the port. When the first connection unit 510 and the external input unit 20 are connected wirelessly, pairing can be determined.

As described above, a signal can be received depending on whether the second external electrode unit 600 is coupled or not and the type of connection. Therefore, by the external input unit 20 of the ECG measuring device generating an additional signal depending on whether the second external electrode unit is coupled, the ECG measuring device determines whether the second external electrode unit 600 is coupled or not and the first external electrode unit 500. ) can be determined. The electrocardiogram measurement method of the present invention is not limited to the type of determination of whether the electrodes are coupled or not described above.

When step S420 is completed, the next step, step S423 or step S422, is performed.

Since the description of the second option in step S422 is the same as the above-described step S222, step S423 will be explained.

In step S423, if it is determined that the second external electrode unit 600 is coupled to the external input unit 20, at least one measurement mode that can measure the electrocardiogram using the second external electrode 620 is included. Provides a third option. The third option using the second external electrode unit 600 may provide various image options depending on the use of the second external electrode unit 600.

For example, at least one of the images provided by the third option disables the third electrode 400 and utilizes only the first electrode 200, the second electrode 300, and the second external electrode unit 600. An image measuring the electrocardiogram can be provided as an option. The third option provided by the electrocardiogram measuring device is not only the option of receiving a potential signal using a suitable electrode, but also can guide the preferred posture in a situation where a potential signal is input by using an electrode, such as attaching or holding an electrode. Specifically, when the second external electrode unit 600 is in the form of a pad suitable for measuring potential signals from the chest, the second external electrode unit 620 unit 600 can be attached to the chest to receive potential signals.

In addition, in the method of attaching the first electrode 200 and the second electrode 300 to both hands, a preferred attachment position can be guided, and in attaching the electrode of the second external electrode unit 600 to the chest, It can guide the desired attachment location. A method of providing a third option may be output through a display unit coupled to an electrocardiogram measurement device. In some cases, selection information may be transmitted to a separate external device that is separate from the electrocardiogram measurement device.

Figure 5 is an exemplary diagram to explain an embodiment in which selection information is output to a display or an external device of the present invention.

Hereinafter, an embodiment of the present invention will be described with reference to FIG. 5.

The electrocardiogram measurement method of the present invention provides different options depending on whether the first external electrode and the second external electrode are combined. The electrocardiogram measurement method provides at least one option among the first to third options.

As shown in Figure 5, when providing the first option (A), it includes at least one electrocardiogram measurement option for measuring LL (left foot). When receiving a potential signal using three electrodes, the attached electrodes can be divided into a main electrode and a sub electrode to receive the potential signal. For example, referring to Figure 5, when measuring a potential signal by attaching electrodes to the left hand, right arm, and leg, the main electrode is set to the (+) pole of the left hand, and the secondary electrode is set to the (-) pole of the right arm and left foot. Electrocardiogram measurement results are calculated using the potential difference between electrodes.

When providing a third option (B), it includes at least one electrocardiogram measurement option for measuring V1 (chest). When receiving a potential signal using three electrodes, the attached electrodes can be divided into a main electrode and a sub electrode to receive the potential signal. For example, referring to Figure 5, in the third option (B), the main electrode is the right hand (+) pole, and the secondary electrodes are the left and chest (-) poles, so that the potential difference between the right and left electrodes, and the potential between the right and left hands ECG measurement results are calculated using the average of and the potential difference between the chest electrodes. In some cases, detailed potential signals may be received by attaching multiple electrodes to the same area. When multiple electrodes are attached to the same area to receive detailed potential signals, the accuracy of electrocardiogram measurement results can be improved.

Although not shown in FIG. 5, when providing a second option, it includes at least one option for electrocardiogram measurement using the third electrode 400. In the second option, a potential signal can be input using all of the first electrode 200 to the third electrode 400. However, in some cases, a potential signal can be received through two electrodes by using only the first electrode 200 and the second electrode 300 without using the third electrode 400.

In the above-described first to third options, when receiving a potential signal using electrodes, the electrocardiogram is not necessarily measured at three locations, but may be measured at only two electrodes depending on the user's option selection.

In this way, even if the positions of the attached electrodes are the same, the electrocardiogram measuring device measures the potential signal by distinguishing between the main electrode and the sub electrode, so the user selects one selection information from the first to third options provided. shall. The electrocardiogram measurement method receives selection information selected by the user and operates in one measurement mode according to the input selection information. The present invention is not limited to the number of electrodes described above. In some cases, the potential signal can be measured using all four electrodes.

In terms of providing a choice of electrocardiogram measurement method and attaching electrodes, the present invention is not limited to the above-described examples. The subject can be measured using a variety of measurement methods that can measure the electrocardiogram by varying the number or attachment location of electrodes, such as commonly performed standard limb leads, amplified limb leads, single leads, and multiple leads.
