[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application only for the purpose of describing specific embodiments of the present application, and is not intended to limit the present application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] As Figures 1 to 3As shown, the ECG monitoring device 1000 provided by the embodiment of the present application includes an ECG monitoring host 100 and a connecting base 200. The ECG monitoring host 100 includes a first shell 11 and a second shell 12 connected in two parts. The first shell 11 and the second shell 12 enclose a receiving cavity (not shown in the figure) in which a circuit board 20 is arranged. The second shell 12 is fixedly installed with a conductive connecting piece 30. The connecting base 200 is provided with a metal contact 210 corresponding to the conductive connecting piece 30. One end of the conductive connecting piece 30 extends into the receiving cavity and is in conductive connection with a conductive point 21 of the circuit board 20. The other end of the conductive connecting piece 30 extends out of the outer surface of the second shell 12. When the ECG monitoring host 100 is installed on the connecting base 200, the conductive connecting piece 30 is in abutment and conductive communication with the metal contact 210. The conductive connecting piece 30 is fixedly installed on the second shell 12 and is in conductive connection with the conductive point 21 of the circuit board 20. Specifically, the first shell 11 and the second shell 12 are connected in buckling. The conductive connecting piece 30 is in abutment and conductive communication with the circuit board 20, thereby ensuring that the conductive connecting piece 30 and the circuit board 20 are in stable electrical connection.

[0036] Since the ECG monitoring host 100 needs to transmit the collected ECG data to an ECG analysis system for disease analysis, it is required to be disassembled for use. Therefore, in order to fully consider the influence of frequent disassembly and installation of the ECG monitoring host 100 on the conductive connecting piece 30, the second shell 12 is integrated with the conductive connecting piece 30. If the conductive connecting piece 30 is damaged during use, the user can directly replace the second shell 12, which is convenient to install and controllable in cost. During replacement, the circuit board 20 does not need to be disassembled and will not be damaged, thereby avoiding the situation that the ECG monitoring host 100 is scrapped due to replacement of the conductive connecting piece 30.

[0037] In this embodiment, the circuit board 20 is detachably installed in the first shell 11. In the present application, the conductive connecting piece 30 is fixed on the second shell 12. When the conductive connecting piece 30 has a poor conductivity or other problems, the second shell 12 can be separated from the first shell 11 to separate the conductive connecting piece 30 from the circuit board 20, so that the conductive connecting piece 30 can be replaced. In this embodiment, the second shell 12 and the first shell 11 are detachably connected in a buckling manner, which facilitates the disassembly of the second shell 12 from the first shell 11. It can be understood that in other embodiments, the second shell 12 can also be assembled and connected to the first shell 11 in a screwing manner by means of bolts, which will not be described here.

[0038] As shown in the figure, the ECG monitoring host 100 includes a first shell 11 and a second shell 12 connected in two parts. The first shell 11 and the second shell 12 enclose a receiving cavity (not shown in the figure) in which a circuit board 20 is arranged. The second shell 12 is fixedly installed with a conductive connecting piece 30. The connecting base 200 is provided with a metal contact 210 corresponding to the conductive connecting piece 30. One end of the conductive connecting piece 30 extends into the receiving cavity and is in conductive connection with a conductive point 21 of the circuit board 20. The other end of the conductive connecting piece 30 extends out of the outer surface of the second shell 12. When the ECG monitoring host 100 is installed on the connecting base 200, the conductive connecting piece 30 is in abutment and conductive communication with the metal contact 210. The conductive connecting piece 30 is fixedly installed on the second shell 12 and is in conductive connection with the conductive point 21 of the circuit board 20. Specifically, the first shell 11 and the second shell 12 are connected in buckling. The conductive connecting piece 30 is in abutment and conductive communication with the circuit board 20, thereby ensuring that the conductive connecting piece 30 and the circuit board 20 are in stable electrical connection. Figures 6 to 9As shown, in this embodiment, the ECG monitoring device 1000 includes a lead wire 300. One end of the lead wire 300 is mounted on a connecting base 200 and exposed to form a metal contact 210. An electrode clip 400 is provided at the end of the lead wire 300 away from the connecting base 200. A defibrillator resistor 500 is connected in series between the electrode clip 400 and the lead wire 300. In other words, the ECG monitoring device 1000 of this embodiment integrates the defibrillator resistor 500 within the electrode clip 400. When applied in high-current treatment scenarios such as defibrillation or high-voltage electrosurgical excision, the defibrillator resistor 500 can prevent defibrillation energy from being conducted and leaked through the lead wire 300, thus affecting the treatment effect, and it does not affect the accuracy of the ECG signal acquired by the electrode clip 400. The defibrillator resistor 500 is located inside the electrode clip 400, reducing the overall size of the ECG monitoring device 1000. In this embodiment, the number of lead wires 300 is configured to be three, five, or ten, so that the ECG monitoring device 1000 can be equipped with different numbers of lead wires 300 according to different usage needs, and achieve different ECG monitoring purposes, thereby improving the convenience and comfort of the ECG monitoring device 1000 during the wearing process.

[0039] It should be noted that one end of the defibrillator resistor 500 can be connected to the electrode clip 400 by welding, and the other end can also be connected to the corresponding lead wire 300 by welding. At the same time, the lead wire 300 needs to be fixed with an anti-tension ring structure and other components for internal mold coating treatment, and then external mold coating is performed to construct the marking of each lead point and the anti-bending structure.

[0040] like Figure 7 As shown, in this embodiment, the ECG monitoring device 1000 has SR mesh tails 600 between the lead wire 300 and the electrode clip 400, and between the lead wire 300 and the connecting base 200. The structure of the SR mesh tails 600 includes, but is not limited to, "I-shaped" and "spiral". The SR mesh tails 600 between the connecting base 200 and the lead wire 300 are distributed on the upper and lower sides of the connecting base 200. Each lead wire 300 is bonded to the SR mesh tail 600 using an adhesive coating process. Combined with the adhesive channel structure design, stress relief is achieved during bending of the lead wire 300, thereby improving the product lifespan of the ECG monitoring device 1000.

[0041] like Figure 3As shown, in this embodiment, the conductive connector 30 includes a spring pin 31, which is fixedly mounted on the second housing 12. One end of the spring pin 31 protrudes from the upper part of the second housing 12, and the other end abuts against the conductive point 21 of the circuit board 20, thus achieving a conductive connection between the spring pin 31 and the circuit board 20. This ensures the stability of the electrical connection between the conductive connector 30 and the circuit board 20. The spring pin 31 is assembled onto the second housing 12 using a plug-in mating method, and then the spring pin 31 and the second housing 12 are connected and fixed with insulating sealant. It can be understood that in other embodiments, the spring pin 31 can also be connected and fixed to the second housing 12 using a tight fit method, which will not be elaborated here.

[0042] like Figure 2 , Figure 3 As shown, in this embodiment, the ECG monitoring host 100 also includes a battery 40, which is mounted on the second housing 12 and electrically connected to the circuit board 20. In this embodiment, the battery 40 supplies power to the circuit board 20 to meet the power consumption requirements of the ECG monitoring host 100. The second housing 12 is provided with a mounting part 41 for accommodating the battery 40.

[0043] like Figure 4 , Figure 5 As shown, this application also provides an electrocardiogram (ECG) monitoring device 1000, including a connecting base 200 and the aforementioned ECG monitoring host 100; the ECG monitoring host 100 is detachably connected to the connecting base 200; the ECG monitoring host 100 is electrically connected to the connecting base 200 via a conductive connector 30. Figure 5 As shown, in this embodiment, the connecting base 200 is provided with metal contacts 210, which are correspondingly provided with conductive connectors 30. The conductive connectors 30 and their corresponding metal contacts 210 are connected and electrically conductively in a point-to-point manner. That is, the number of conductive connectors 30 provided on the ECG monitoring host 100 corresponds one-to-one with the metal contacts 210 on the connecting base 200 to achieve conductive connection. In other words, when the ECG monitoring host 100 is connected to the connecting base 200, the ECG monitoring host 100 and the connecting base 200 can be electrically connected in a point-to-point manner. This minimizes the design of the electrical connection between the ECG monitoring host 100 and the connecting base 200, reduces the size of the host, and meets the wearable usage requirements of the ECG monitoring device 1000.

[0044] In this embodiment, the ECG monitoring host 100 is connected to the connecting base 200 by a snap-fit ​​connection. This snap-fit ​​connection method facilitates the assembly and disassembly of the ECG monitoring host 100 and the connecting base 200.

[0045] like Figure 5As shown, in this embodiment, at least one telescopic buckle 230 is provided on the connecting base 200. The telescopic buckle 230 is arranged on the connecting base 200 and is used to limit and fix the ECG monitoring host 100 on the connecting base 200. The telescopic buckle 230 is connected to the unlocking button 240. When the user presses the unlocking button 240, the limiting function of the telescopic buckle 230 on the ECG monitoring host 100 can be released, making it convenient to detach the ECG monitoring host 100 from the connecting base 200.

[0046] In another embodiment, the connecting base 200 is provided with a fixing buckle 220 and a telescopic buckle 230, which are arranged on opposite sides of the connecting base 200. The connecting base 200 can be engaged with the ECG monitoring host 100 via the fixing buckle 220 and the telescopic buckle 230. When the ECG monitoring host 100 is assembled on the connecting base 200, one end of the ECG monitoring host 100 can be first fixed to the fixing buckle 220 of the connecting base 200, and then the ECG monitoring host 100 is driven to rotate towards the telescopic buckle 230 until it engages with the telescopic buckle 230. Here, the connecting base 200 is also provided with an unlocking button 240. When the unlocking button 240 is pressed, it can force the telescopic buckle 230 to unlock from the ECG monitoring host 100, thus satisfying the need to remove the ECG monitoring host 100 from the connecting base 200.

[0047] like Figure 3 , Figure 5 As shown, in this embodiment, when the ECG monitoring host 100 is connected to the connecting base 200, the conductive connector 30 is arranged in the circumferential direction of the telescopic buckle 230 on the connecting base 200. That is, the metal contacts 210 on the connecting base 200 are arranged in the circumferential direction of the telescopic buckle 230 on the connecting base 200. Specifically, the metal contacts 210 can be arranged in the half area on the connecting base 200 where the telescopic buckle 230 is located. This way, when the ECG monitoring host 100 is assembled on the connecting base 200, the conductive connector 30 will only abut against the corresponding metal contacts 210 on the connecting base 200 when the ECG monitoring host 100 is finally flipped towards the connecting base 200. This reduces the impact of the ECG monitoring host 100 on the conductive connector 30 when it is assembled on the connecting base 200.

[0048] like Figure 5As shown, in some embodiments, a sealing ring 250 is arranged on the connecting base 200; when the ECG monitoring host 100 is connected to the connecting base 200, the sealing ring 250 is arranged on the outer periphery of the conductive connecting piece 30 and is deformed under pressure, and the deformed sealing ring 250 can seal the assembly of the connecting base 200 and the ECG monitoring host 100, so as to play a waterproof sealing role for the assembly between the ECG monitoring host 100 and the connecting base 200, so that the ECG monitoring device 1000 has a waterproof function. Here, the sealing ring 250 is assembled to the connecting base 200 in a manner of gluing or bonding.

[0049] Embodiment Two

[0050] As Figure 10 With Figure 11 The ECG monitoring device 1000 further includes a flexible substrate 201 and a lead layer 202 and an ECG patch electrode 203 printed on the flexible substrate 201, one end of the lead layer 202 is mounted on the connecting base 200 and exposes the metal contact 210, and the other end is in conductive connection with the ECG patch electrode 203.

[0051] The overlapping part of the connecting layer 204 and the lead layer 202 forms a first conductive area, and the overlapping part of the connecting layer 204 and the ECG patch electrode 203 forms a second conductive area.

[0052] The embodiment of the present application prepares the lead layer 202 and the ECG patch electrode 203 on the flexible substrate 201 according to the conductive pattern, respectively, realizes conductive connection by lapping the lead layer 202 and the ECG patch electrode 203 through the connecting layer 204, and cuts the outer contour of the flexible substrate 201 along the lead layer 202 and the ECG patch electrode 203 as needed, thereby forming the outer contour of the ECG monitoring host 100. The connecting layer 204, the ECG patch electrode 203 and the lead layer 202 constitute a series circuit, and in the application to a strong current treatment scene such as defibrillation or high-voltage electrotome, the connecting layer 204 additionally provided on the flexible substrate 201 can prevent defibrillation energy from being conducted and leaked through the ECG patch electrode 203 and the lead layer 202, thereby affecting the treatment effect, and will not affect the accuracy of the bioelectric signal collected by the ECG patch electrode 203. The embodiment proposes to use the connecting layer 204 made by printing process, which is light and thin in shape, compact in product structure, connected in series with the ECG patch electrode 203 and the lead layer 202, and does not need other lead connection, so as to replace the traditional defibrillation patch resistor which must be used due to the safety requirements of the monitoring equipment. The traditional patch resistor is too large in size and needs to be connected by lead when used, which is heavy to use and cannot be used in compact physiological monitoring equipment. Moreover, the product provided by the embodiment is light in size and small in structure, which is also suitable for home remote monitoring. In particular, in the defibrillation treatment process, the patient needs to bear multiple defibrillation strong currents to restore the heart function. If the connecting layer 204 is not provided, the defibrillation energy will enter the ECG monitoring host 100 through the ECG patch electrode 203 and the lead layer 202, thereby causing the ECG monitoring host 100 to be destroyed by strong current. In the embodiment, the conductive materials used by the lead layer and the ECG patch electrode 203 are different. In order to avoid the chemical reaction caused by the contact of different conductive materials from affecting the accuracy of the signal collected by the ECG patch electrode 203, for example, the lead layer 202 is made of conductive metal, and the ECG patch electrode 203 is made of silver chloride material. The contact of the conductive metal and the silver chloride will cause chemical reactions such as displacement reaction, combination reaction, etc. A partition is provided between the lead layer 202 and the ECG patch electrode 203, which is used to isolate the contact between the lead layer 202 and the ECG patch electrode 203, thereby avoiding the contact reaction caused by the contact of different conductive materials. In addition, the lead layer 202 and the ECG patch electrode 203 are conductively connected through the connecting layer 204, and the connecting layer 204 provided by the embodiment can withstand multiple strong current impacts. After the cardiac defibrillation treatment is completed, the ECG monitoring host 100 can still be used normally to collect and record the ECG signal, thereby enhancing the reliability of the equipment. If the resistance value of the connecting layer 204 is greater than 50K ohms, signal noise will be generated, which will affect the accuracy of the bioelectric signal collection.

[0053] In this embodiment, the connection layer 204 is printed on the ECG patch electrode 203 and the lead layer 202 using a printing process, without affecting the wearing weight, facilitating long-term uninterrupted wearing of the user to be tested, monitoring the biological electrical signal, especially the ECG for a long time, which can help the user to be tested to monitor the health of the heart or hidden diseases more comprehensively, and in a strong current treatment environment, such as the defibrillation strong current or the high voltage of the electrotome applied to the user to be tested, which will be conducted to the ECG monitoring host 100 through the lead layer 202, resulting in the host being damaged by the strong current. Therefore, the ECG monitoring device 1000 provided in the embodiment not only considers the light wearing of the user to be tested, facilitating long-term uninterrupted wearing, but also considers the use requirements of the monitoring scene, ensuring that the ECG monitoring host 100 can collect accurate biological electrical signals in real time, and the device is more reliable and safe.

[0054] The connection layer 204 and the lead layer 202 form a first conductive area, the connection layer 204 and the ECG patch electrode 203 form a second conductive area, the first conductive area and the second conductive area are in conductive communication, and the connection layer 204 can conductively connect the ECG patch electrode 203 and the lead layer 202 through the first conductive area and the second conductive area. The use of the split design of the lead layer 202, the ECG patch electrode 203 and the connection layer 204 can adapt to more use environments and preparation requirements, improve the applicability of the biological electrical signal collection of the lead layer 202, and ensure that the connection layer 204 can conductively connect the ECG patch electrode 203 and the lead layer 202 and stably transmit signals.

[0055] Meanwhile, in this embodiment, the ECG patch electrode 203 is also provided with the connection layer 204 and the electrode mark 205 printed in the same layer, and the same layer printing can refer to printing the connection layer 204 and the electrode mark 205 at the same time in one printing process. Preferably, the materials of the connection layer 204 and the electrode mark 205 are the same, which can be one of conductive ink, conductive polymer and conductive carbon. The connection layer 204 is used to conductively connect the lead layer 202 and the ECG patch electrode 203. The electrode mark 205 is used to mark the connection site of the ECG patch electrode 203. The connection layer 204 and the electrode mark 205 are printed in the same layer, which simplifies the process, uses the same material to print the connection layer 204 and the electrode mark 205 at the same time, and further reduces the product cost.

[0056] The technical features of the above embodiments can be combined in any way. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0057] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application, and as long as the above embodiments are made within the scope of the present application, the appropriate changes and variations of the above embodiments fall within the scope of the present application.
