Description

Technical Field

[0001] This application relates to the field of electrocardiogram (ECG) measuring instruments, and more particularly to a patch-type ECG measuring instrument. Background Technology

[0002] With advancements in medical technology and increasing emphasis on health management, portable, wearable electrocardiogram (ECG) monitoring devices, especially patch-type ECG monitors, have gained widespread application in outpatient ECG monitoring (such as Holter monitoring), cardiac rehabilitation monitoring, home health management, and exercise physiology monitoring due to their advantages of small size, comfortable wear, and ease of use. Existing patch-type ECG monitors typically employ an integrated design, encapsulating ECG signal acquisition electrodes, signal processing circuitry, power supply (such as a button battery), and wireless transmission module (such as Bluetooth) within a compact, adhesive patch housing. Users must directly attach the patch to a specific location on the chest (such as the left sternal border or the apex of the heart), allowing ECG signals to be acquired through contact between the built-in electrodes and the skin. The main unit is then connected to the patch. However, misalignment of the electrodes during connection can easily occur, leading to signal loss and impacting the user experience. Furthermore, the patch cannot be reused; the integrated conductive area within the patch increases its cost, making replacement difficult and creating an economic burden. Utility Model Content

[0003] The technical problem this application aims to solve is that electrode misalignment easily occurs when the host and patch are connected, leading to signal loss and affecting user experience; the patch cannot be reused, and its integrated conductive area results in high cost and difficult replacement, creating an economic burden. To address the above-mentioned shortcomings of the prior art, this application provides a patch-type electrocardiogram (ECG) measuring instrument.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is:

[0005] A patch-type electrocardiogram (ECG) measuring device is constructed, comprising a first measuring unit with a conductive area and five sets of conductive contacts within the conductive area, and a host connected to the first measuring unit. The host is connected to the conductive contacts. The device is characterized in that: the first measuring unit has N sets of electrode pads, each set of electrode pads being electrically connected to a set of conductive contacts; the first measuring unit is connected to 5-N sets of second measuring units, each set of second measuring units having a fifth electrode pad; the sum of the electrode pads on the first measuring unit and all the electrode pads on the second measuring units is 5, and each electrode pad corresponds to a set of conductive contacts; ECG signals are picked up through the five sets of electrode pads on the first and second measuring units; the first and second measuring units are detachably connected via a connecting wire, which is electrically connected to the fifth conductive contacts and the fifth electrode pad.

[0006] Preferably, the host and the conductive area are connected by a button structure, and the connecting line is connected to the first measuring part and the second measuring part by a button structure. The button structure mechanically connects the host and the conductive area and realizes electrical signal connection, and the button structure mechanically connects the connecting line to the first measuring part and the second measuring part and realizes electrical signal connection.

[0007] Preferably, the button structure includes a conductive button and a conductive buckle corresponding to the conductive button. The conductive buckle is inserted into the conductive button to connect the main unit to the second measuring unit and to connect the connecting wire to the first measuring unit and the second measuring unit.

[0008] Preferably, if one of the conductive button and the conductive buckle is placed on the host, the other is placed in the corresponding conductive area to form a button structure for connection. If one of the conductive button and the conductive buckle is placed on the connecting line, the other is placed on the corresponding first measuring part and second measuring part to form a button structure for connection.

[0009] Preferably, the electrode plates on the first measuring unit are connected to the second measuring unit via a button structure, and each group of electrode plates is connected to a group of second measuring units via a button structure.

[0010] Preferably, one of the conductive button and the conductive buckle is placed on the first measuring part, and the other is placed on the corresponding second measuring part to form a button structure for connection.

[0011] Preferably, the main unit includes a housing and a control board placed inside the housing. The ECG signals picked up by the electrode pads are transmitted to the control board. The beneficial effects of this application are: the main unit is connected to the first measuring unit via a button structure, facilitating the mechanical and electrical connection between the main unit and the conductive area, enabling the signals picked up by the electrode pads to be transmitted to the main unit. Simultaneously, the second measuring unit and the first measuring unit are connected by a connecting cable, reducing the cost of the patch-type ECG device. The first and second measuring units are also connected via a button structure with the connecting cable, making the connection more convenient and eliminating the need to consider electrical signal transmission issues during connection. The electrode pads of the first measuring unit can be connected to the second electrode pads via a button interface, reducing the cost of the patch-type ECG device. Furthermore, the adhesion area to the skin is smaller, making it easier to remove the second electrode pads after use, increasing the reusability of the core components of the patch-type ECG device, lowering the operating cost, and facilitating connection and use.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this application. Obviously, the described embodiments are some embodiments of this application, but not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0021] A preferred embodiment of this application provides a patch-type electrocardiogram (ECG) measuring device; such as... Figures 1-3As shown, the device includes a first measuring unit 20 attached to the chest. A conductive area 50 is located in the center of the first measuring unit, and a host unit 10 connected to the first measuring unit and transmitting electrical signals is mounted on the conductive area. The first measuring unit 20 includes four sets of electrode pads and five sets of conductive contacts within the conductive area. The first electrode pad 200 is electrically connected to the first conductive contact 500, which can be achieved via an FPC flexible circuit board or similar means. The other three sets of electrode pads are connected in the same way: the second electrode pad 201 is electrically connected to the second conductive contact 501; the third electrode pad 202 is electrically connected to the third conductive contact 503; and the fourth electrode pad 203 is electrically connected to the fourth conductive contact 503. The first, second, third, and fourth conductive contacts are located at different positions on the human body surface and are used to pick up electrocardiogram (ECG) signals. The second measuring unit 20 is attached to the chest, and ECG signals are picked up through the four sets of electrode pads. The conductive area is also provided with a fifth conductive contact 504. The first measuring part 20 is also provided with a fifth conductive point corresponding to the fifth conductive contact. The fifth conductive point is connected to a connecting line 30. The other end of the connecting line is connected to the second measuring part 40. The second measuring part is provided with a fifth electrode 400. The fifth conductive contact 504 is electrically connected to the fifth electrode 400 through the fifth conductive point and the connecting line, thereby forming five sets of electrode 400 to pick up the electrocardiogram signal and perform electrocardiogram measurement. It should be noted that existing designs can be used for the specific electrode pads to acquire ECG signals. This application does not protect this content, so it will not be described in detail. The button 300 structure ensures the connection of the components and transmits electrical signals during the connection, which facilitates electrode contact during connection and makes the connection more convenient. The connection in this application includes physical connection and electrical connection. Electrical connection is to realize the transmission of electrical signals, while physical connection is to connect the two sets of components in a structural way. For example, when the connecting line is connected to the first measuring part, it includes connecting the connecting line to the body of the first measuring part. When the first measuring part is pulled, the connecting line will inevitably move together. At the same time, the electrical signal is also transmitted from the first measuring part to the connecting line through the connection.

[0022] Specifically, such as Figures 1-3As shown, to facilitate the connection between the connecting wire and the fifth conductive contact, one end of the connecting wire is connected to the fifth conductive contact using a button 300 structure. The fifth conductive contact can be either a button or a snap, corresponding to one end of the connecting wire being either a snap or a button. Since the button and snap are made of metal, they inherently possess conductive properties. Therefore, when the button is inserted into the snap to form a snap, the structural connection between the connecting wire and the first measuring unit is achieved, and the electrical connection between the connecting wire 30 and the first measuring unit is also achieved. Here, the fifth conductive point is used as the button for explanation. The button placed on the first measuring unit and the fifth conductive contact 504 are connected through an FPC flexible board to achieve electrical signal transmission. When the connecting wire is connected to the first measuring unit, the button is inserted into the snap, and the connecting wire is connected to the first measuring unit. At the same time, the electrical signal is transmitted to the connecting wire through the button 300. The other end of the connecting wire is connected to the second measuring unit using the same button 300 structure to achieve electrical signal transmission, thereby realizing the transmission of the electrical signal from the fifth conductive contact to the fifth electrode plate 400. Therefore, the button 300 structure should be made of conductive material to transmit electrical signals, such as metal. Meanwhile, since the connecting cable is connected to the first and second measuring units via the button 300, it is easy to disassemble. After use, only the first and second measuring units need to be discarded, while the connecting cable can be kept for reuse. In addition, the cost of the connecting cable is lower when picking up ECG signals at long distances.

[0023] Furthermore, such as Figure 1 and Figure 4-5 As shown, the host 10 includes a housing 100 and a control board 101 placed inside the housing. The acquired ECG signals are transmitted to the control board via conductive contacts. A SIM card 102 is installed on the control board for transmitting the acquired ECG signals. Control buttons 103 are provided on the inner side of the housing. The back of the housing also uses a button structure 300 to connect to the conductive area. However, only three sets of button structures are needed: the top two sets and the bottom set. These three sets of button structures are sufficient to determine the position of the host. Therefore, the first conductive contact 500 and the second conductive contact 501... The third conductive contact 502 is connected to the main unit via a button 300 structure for electrical signal transmission. The fourth conductive contact 503 and the fifth conductive contact 504 only need to use conventional electrode contact, or the fourth and fifth conductive contacts can be set as a button structure connection. The specific button 300 structure is the same as described above, and will not be repeated here. In this way, the main unit is connected to the second measuring unit, which facilitates the connection and positioning of the main unit and the conductive area. There is no need to consider whether the electrodes are in contact during connection. The electrical signal transmission of five sets of conductive contacts can be guaranteed by three sets of button 300 structures, making operation more convenient.

[0024] A patch-type electrocardiogram (ECG) measuring device according to a preferred embodiment of this application; such as... Figures 6-7As shown, the difference from Embodiment 1 is that only two sets of electrode pads are provided on the first measuring unit 20, and the two sets of second electrode pads are connected by two sets of button 300 structures, which makes its electrocardiogram measurement range wider and more flexible.

[0025] A patch-type electrocardiogram (ECG) measuring device according to a preferred embodiment of this application; the difference from embodiments one and two is that the first electrode 200, the second electrode 201, the third measuring part 202 and / or the fourth measuring part 203 are electrically connected to the second measuring part 40 through a button structure. The specific button structure is the same as described above and will not be repeated here. This method allows the first measuring part 20 to be reused, and the second measuring part 40 can be discarded after use, resulting in lower usage costs. Furthermore, since only the second measuring part is pasted, the pasting area between the first measuring part and the skin is reduced, making it easier to remove the ECG device from the skin after use.

[0026] It should be understood that this application has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this application. Furthermore, based on the teachings of this application, these features and embodiments can be modified to suit specific circumstances and materials without departing from the spirit and scope of this application. Therefore, this application is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this application.
