[0034] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, and circuits are omitted to prevent unnecessary details from obstructing the description of the present application.

[0035] In order to monitor health in real time, people have an increasing demand for monitoring equipment, such as wearable ECG devices (ECG stickers, ECG clothing, heart rate belts, etc.) used to monitor human vital signs. At present, wearable ECG devices usually have two structures. The first is composed of only a controller, that is, the controller collects and processes ECG information. The second is composed of a controller and a connector, that is, the connector collects ECG information and then the controller processes it.

[0036] Among them, there are usually two types of wearable devices composed of controllers. One is to fix the controller directly on the wearable device (for example, clothing, patch electrodes, etc.). However, in this way, it cannot be disassembled, resulting in the wearable device being unable to be cleaned. The other is to connect the wearable device to the controller through accessories such as magnets or buckles. In this way, the controller can be removed to clean the wearable device. However, when a magnet is used to connect the wearable device to the controller, the connection firmness of the magnetic suction method is poor and easy to fall off, resulting in the wearable device being unsuitable for use in sports scenes and having low versatility; when a buckle is used to connect the wearable device to the controller, although the buckle method has better connection firmness, the buckle has poor antioxidant capacity and is easy to wear. When the wearable device needs to set up multiple acquisition channels, the buckle is large in size, which is not suitable for the miniaturization and lightweight development of the device, and the buckles need to be installed one by one, which is cumbersome to operate.

[0037] The discrete ECG device consists of a controller and a connector, and the controller and the connector can be disassembled to meet the requirements of cleaning. However, as the application scenarios required by wearable devices increase, for example, the Band-Aid form (i.e. ECG patch) is suitable for use during sleep, and the clothing form (i.e. ECG clothes) is suitable for use during exercise, and the disassembly structure composed of the controller and the connector is usually only suitable for specific types of devices, and cannot be shared by different types of wearable devices. For example, wearable items using patch electrodes (i.e. ECG patches) and wearable items using clothing (i.e. ECG clothes) cannot share the same controller and connector disassembly structure, resulting in poor compatibility and low versatility of such ECG devices, and each wearable device needs to be equipped with a corresponding disassembly structure, which has a high production cost.

[0038] To this end, the present application provides an ECG acquisition device and a wearable device, wherein the connection component and the controller in the ECG acquisition device are detachably connected, so that the wearable device using the ECG acquisition device can be washed. Moreover, the ECG acquisition device in the present application has strong compatibility and high versatility, and can be applied to different types of wearable devices.

[0039] The following is an exemplary introduction to the ECG acquisition device and wearable device provided in the present application in conjunction with the accompanying drawings.

[0040] The wearable device provided in the present application includes an ECG acquisition device 1 and a wearable device 2, wherein the wearable device 2 provided in the embodiment of the present application can be an ECG detection sticker, an ECG detection belt, and an ECG detection garment. For example, Figure 1 As shown, the wearable component 2 may be an ECG detection sticker, and the ECG acquisition device 1 is fixed to the ECG detection sticker to collect ECG information. Figure 2 As shown, the wearable item 2 may be an ECG detection belt, and Velcro 21 may be provided on both sides of the ECG detection belt. The ECG acquisition device 1 is fixed to the area of ​​the ECG detection belt where Velcro 21 is not provided, so as to collect ECG information. Figure 3 As shown, the wearable item 2 can be an ECG detection garment, and the ECG acquisition device 1 can be fixed on the ECG detection garment by Velcro 21, or can be directly fixed on the ECG detection garment. Among them, the ECG acquisition device 1 provided in the embodiment of the present application has strong compatibility and high versatility, and can be fixed on any wearable item 2 to form a wearable device. Here, it is worth noting that the wearable item 2 provided in the embodiment of the present application can also be other structures, and this application does not make specific restrictions on this.

[0041] In order to make the wearable device provided by the present application meet the requirements of cleaning, in one example, Figure 4As shown, the ECG acquisition device 1 provided in the present application may include a connecting component 11 and a controller 12, wherein the connecting component 11 is fixed on the wearable component 2, and the controller 12 and the connecting component 11 are detachably connected so that after the controller 12 is detached, the wearable device using the ECG acquisition device 1 can meet the cleaning requirements.

[0042] Among them, optionally, the connection component 11 may include a shell 111 and a collection component 112, the first surface of the collection component 112 is fixedly connected to the first surface of the shell 111, and the second surface of the collection component 112 is fixed to the wearable component 2. In order to enable the controller 12 to obtain electrocardiographic information based on the connection component 11, a plurality of conductive members 1121 are provided on the first surface of the collection component 112, and one end of the plurality of conductive members 1121 away from the first surface of the collection component 112 passes through the shell 111 and is fixedly connected to the shell. In this example, the controller 12 is detachably connected to the second surface of the shell 111, and the side of the controller 12 facing the shell 111 abuts against one end of the plurality of conductive members 1121 to receive the electrical signal transmitted by the collection component 112, that is, the controller 12 can obtain electrocardiographic information through the plurality of conductive members 1121.

[0043] Here, it can be understood that in order to improve the overall flatness of the collection component 112 and to improve the effect of the collection component 112 on collecting electrocardiographic information, the first surface of the collection component 112 and the second surface of the collection component 112 can be arranged relatively parallel, that is, the collection component 112 as a whole is in the shape of a flat plate, and the first surface of the collection component 112 and the second surface of the collection component 112 can also adopt other positions, and the present application does not make any specific restrictions on this.

[0044] In this way, by setting the connection component 11 and the controller 12 as a detachable structure, the wearable device using the ECG acquisition device 1 can meet the requirements of washing and drying, wherein, by setting the conductive member 1121 on the connection component 11, the controller 12 can obtain ECG information through the conductive member 1121 to ensure the acquisition reliability of the ECG acquisition device 1. Moreover, the acquisition component 112 in the connection component 11 is a universal structure, that is, it can be fixed to various types of wearable items 2 to collect ECG information. For example, when the wearable item 2 is an ECG detection sticker or an ECG detection belt, the second side of the acquisition component 112 can be fixed to the wearable item 2 by pasting; when the wearable item 2 is an ECG detection garment, the second side of the acquisition component 112 can be fixed to the wearable item 2 by stitching. In this way, the acquisition component 112 can be fixed to any type of wearable item 2 without changing its structure, and has strong versatility and high fixing flexibility. At the same time, the connection component 11 and the controller 12 are detachable structures, so the controller 12 can also be suitable for the use requirements of any wearable item. For example, assuming that the wearable item 2 is a structure that does not need to be cleaned, such as an ECG detection sticker or an ECG detection belt, the connection component 11 and the controller 12 can always maintain a fixed connection to collect ECG information; when the wearable item 2 is a structure that needs to be cleaned, such as an ECG detection shirt, the controller 12 can be removed to meet the cleaning requirements. In this way, the connection component 11 and the controller 12 are set to a general structure with strong compatibility, so that the ECG acquisition device 1 can be fixed on any wearable item 2 to form a wearable device.

[0045] In order to enable the housing 111 to be fixed to the wearable device 2, in one example, as Figure 4 As shown, the edge of the shell 111 is surrounded by a plurality of first connecting portions 111A, and the shell 111 can be fixed to the wearable item 2 by means of stitching or adhesive. For example, assuming that the wearable item 2 is a piece of clothing, for example, as shown in FIG. Figure 3 When the ECG detection clothing is shown, the shell 111 can be fixed to the wearable item 2 by stitching, which is relatively strong. Assuming that the wearable item 2 is a soft rubber type, such as the ECG detection patch shown in Figure 1, the shell 111 can be fixed to the wearable item 2 by gluing, which is relatively strong. In this way, the shell 111 and the wearable item 2 are fixed by stitching and gluing, which is relatively strong. For different types of wearable items 2, the fixation between the shell 111 and the wearable item 2 can be achieved by changing the connection method between the shell 111 and the wearable item 2, that is, the fixation between the ECG acquisition device 1 and the wearable item 2 is achieved, which has strong compatibility, high versatility, high flexibility, and no need to change the structure of the ECG acquisition device 1, which reduces a certain production cost.

[0046] Optionally, when fixation is performed by suturing, an insulated thread may be used.

[0047] In order to avoid the problem that when the distance between the multiple first connecting parts 111A is too large, fingers or other debris are inserted between the shell 111 and the collecting component 112, causing the collecting component 112 to be damaged, thereby affecting the collection of ECG information, optionally, two first connecting parts 111A among the multiple first connecting parts 111A are used as a group of connecting parts. When sutures are used, fixation can be achieved through the connecting parts, and the distance between each adjacent connecting parts is less than the estimated width of the finger, for example, 1 cm (centimeter), so as to avoid the problem that fingers are inserted between the shell 111 and the collecting component 112, causing the collecting component 112 to be damaged.

[0048] In one example, if Figure 5 As shown, the collection component 112 may include a flexible circuit board 1122 and a conductive structure 1123, the conductive structure 1123 is fixedly connected to the wearable device 2, the conductive structure 1123 is partially electrically connected to the flexible circuit board 1122, and the flexible circuit board 1122 is fixedly connected to the first surface of the housing 111, wherein a plurality of conductive members 1121 are formed on the flexible circuit board. Figure 5 As shown, the ECG acquisition device 1 is provided with three conductive members 1121 as an example for explanation, and the flexible circuit board 1122 is also provided with three channels accordingly. The number of conductive members 1121 and channels can be set according to actual needs, and this application does not make any specific restrictions on this.

[0049] The conductive structure 1123 is fixedly connected to the wearable item 2, that is, the ECG acquisition device 1 in the present application is doubly fixed on the wearable item 2. The first fixation is to fix the shell 111 and the wearable item 2 by stitching and gluing, and the second fixation is to fix the shell 111 and the wearable item 2 by the conductive structure 1123. In this way, the firmness between the ECG acquisition device 1 and the wearable item 2 is strengthened by the double fixation, avoiding the problem that the ECG acquisition device 1 and the wearable item 2 are separated due to foreign objects or weak firmness, thereby affecting the ECG detection effect.

[0050] Optionally, the conductive structure 1123 can be made of flexible conductive materials, such as textile electrodes, which have a high degree of integration with the wearable component 2. In order to reduce the contact impedance between the electrode and other materials and the skin to achieve a higher signal-to-noise ratio, optionally, a sponge or the like can be added to the end of the electrode facing the wearable component 2 to thicken it, and then wrapped with a conductive cloth after thickening. In this way, the contact area between the electrode and the skin can be increased, thereby reducing the impedance between the two, so as to improve the transmission reliability of the electrical signal. For example, assuming that the wearable component 2 is an electrocardiogram detection garment, when the electrocardiogram detection garment is worn on the body, the thickened electrode will be tightly attached to the surface of the skin under the elastic force of the electrocardiogram detection garment, so that the contact area between the electrode and the skin is increased, thereby reducing the surface impedance between the electrode and the skin, achieving a high signal-to-noise ratio, and improving the transmission reliability of the electrocardiogram signal.

[0051] In order to avoid the conductive structure 1123 from introducing noise after contacting the skin, thereby affecting the reliability of the transmission of the ECG signal, it is optional, such as Figure 6 As shown, the conductive structure 1123 may include a first portion 1123A, a second portion 1123B and a third portion 1123C, wherein the first portion 1123A is used to contact the skin, the third portion 1123C is used to contact the flexible circuit board 1122 to achieve electrical connection, and the third portion 1123C is connected to the first portion 1123A and the second portion 1123B respectively to achieve electrical connection between the first portion 1123A and the second portion 1123B. The third portion 1123C is in the shape of a long strip as a whole, has a narrow width, and is wrapped with an insulating material to avoid introducing noise after contacting the skin, thereby ensuring the reliability of the transmission of the ECG signal, and the third portion 1123C needs to be exposed to achieve electrical connection with the flexible circuit board 1122.

[0052] In this example, when the wearable item 2 is an ECG detection patch, the lead-out portion of the conductive structure 1123 can be a snap-type to adapt to different types of ECG patch electrodes. This application does not make any specific restrictions on this.

[0053] In order to further achieve electrical connection between the flexible circuit board 1122 and the conductive structure 1123, in one example, as Figure 6 As shown, the flexible circuit board 1122 is provided with a plurality of third connection parts 1122A, and the plurality of third connection parts 1122A are in contact with the exposed third part 1123C to achieve electrical connection, and are fixedly connected by insulating wires or conductive adhesives, etc., so that the flexible circuit board 1122 can be firmly fixed on the conductive structure 1123 while achieving electrical connection, so as to avoid falling off and affecting use. For example, Figure 6As shown, four third connection parts 1122A are provided on the flexible circuit board 1122, and each third connection part 1122A is respectively connected to an exposed third part 1123C, wherein two third connection parts 1122A are respectively connected to two conductive members 1121 one by one, and the other two third connection parts 1122A are connected to the same conductive member 1121, and the third connection parts 1122A and the conductive member 1121 can be connected by a channel formed by printed wires, and the specific number and position of the third connection parts 1122A can be set according to actual needs, and the present application does not make specific restrictions on this.

[0054] Optionally, the third connection portion 1122A may be a connection pair hole, which may be surface-connected with the third connection portion 1122A of the conductive structure 1123 to achieve electrical and fixed connection. Further, the connection pair hole may be composed of two metal pairs of holes, and a connector, such as a bare copper connector, is provided between the two metal pairs of holes to further achieve electrical and fixed connection between the third connection portion 1122A and the third portion 1123C. At the same time, when the insulated thread suture method is adopted, under the extrusion of the suture force, the flexible circuit board 1122 and the conductive structure 1123 are closely attached to each other, reducing the contact impedance between the two, thereby improving the acquisition quality of the ECG signal.

[0055] Optionally, the flexible circuit board 1122 can be a flexible printed circuit (FPC). Since the flexible circuit board 1122 is a soft board structure, in order to avoid fingers or other hard objects from extending between the flexible circuit board 1122 and the housing 111, causing the flexible circuit board 1122 to be damaged, thereby affecting the collection of ECG information. Two third connection parts 1122A of the multiple third connection parts 1122A on the flexible circuit board 1122 serve as a group of connection holes, and the distance between each adjacent connection hole is less than the estimated width of the finger, for example, 1 cm, to avoid the problem of fingers extending between the housing 111 and the flexible circuit board 1122, thereby causing the flexible circuit board 1122 to be damaged. Furthermore, except for the position where the third connection part 1122A is provided on the flexible circuit board 1122, the overall structure of the flexible circuit board 1122 is recessed inside to prevent fingers or other hard objects from extending into and touching the flexible circuit board 1122.

[0056] In this way, by setting a plurality of third connection parts 1122A on the flexible circuit board 1122, an electrical connection between it and the conductive structure 1123 can be achieved, and by fixedly connecting the third connection part 1122A with the exposed third part 1123C, a fixed connection between the flexible circuit board 1122 and the conductive structure 1123 is achieved, thereby avoiding the problem of the flexible circuit board 1122 falling off and affecting the use.

[0057] Furthermore, in order to improve the connection firmness between the flexible circuit board 1122 and the housing 111, as Figure 7 As shown, a plurality of second connection parts 111B are also arranged around the edge of the shell 111, and the positions of the second connection parts 111B correspond one-to-one with the positions of the third connection parts 1122A, so as to facilitate threading or fixing the two by conductive glue. In this way, the flexible circuit board 1122 can also be fixedly connected with the shell 111 through the third connection part 1122A.

[0058] In order to avoid the problem that when the distance between the multiple second connection parts 111B is too large, fingers or other debris are inserted between the shell 111 and the flexible circuit board 1122, causing the flexible circuit board 1122 to be damaged, thereby affecting the collection of ECG information, optionally, two second connection parts 111B among the multiple second connection parts 111B are used as a group of connecting parts. When sutures are used, fixation can be achieved through the connecting parts, and the distance between each adjacent connecting parts is less than the estimated width of the finger, for example, 1 cm, to avoid the problem that fingers are inserted between the shell 111 and the flexible circuit board 1122, thereby causing the flexible circuit board 1122 to be damaged.

[0059] Here, it is worth noting that the shape of the second connection part 111B in the present application can be the same as that of the third connection part 1122A, and the setting position of the second connection part 111B completely overlaps with the setting position of the third connection part 1122A to achieve full contact between the two. The setting position of the second connection part 111B can also partially overlap with the setting position of the third connection part 1122A, as long as a fixed connection can be achieved, and this application does not make specific restrictions on this. In addition, in order to reduce the manufacturing process, the first connection part 111A and the second connection part 111B can be manufactured by the same process.

[0060] The conductive member 1121 in the present application can not only transmit the ECG signal to the controller 12, but also realize accurate alignment connection between the flexible circuit board 1122 and the housing 111 through the conductive member 1121, thereby avoiding the problem of difficult alignment between the flexible circuit board 1122 and the housing 111 when suturing and fixing. Figure 7As shown, a third protrusion 1111 is provided on the second surface of the shell 111, and a plurality of through holes 1111A are provided on the third protrusion 1111, and the number of through holes 1111A corresponds to the number of conductive members 1121, so that the plurality of conductive members 1121 can pass through the shell 111 and the plurality of through holes 1111A. Here, it can be understood that the number of through holes 1111A corresponds to the number of conductive members 1121, and therefore, the plurality of conductive members 1121 pass through the plurality of through holes 1111A one by one to achieve preliminary fixation between the flexible circuit board 1122 and the shell 111, and in order to achieve signal transmission between the conductive members 1121 and the controller 12, one end of the plurality of conductive members 1121 can protrude from the third protrusion 1111 to abut against the receiving portion provided on the controller 12, thereby achieving signal transmission.

[0061] In order to prevent the conductive member 1121 from falling off due to external force after penetrating the through hole 1111A, in one example, Figure 8 As shown, the conductive member 1121 may include a limiting ring 1121A, a first body 1121B and a second body 1121C, the limiting ring 1121A is located on the side wall of the first body 1121B, the outer diameter of the second body 1121C is greater than the outer diameter of the first body 1121B, the first body 1121B protrudes from one side of the third protrusion 1111, the limiting ring 1121A abuts against one side of the third protrusion 1111, the first body 1121B is partially located in the through hole 1111A, and the top of the second body 1121C abuts against the second surface of the shell 111, so that When the conductive member 1121 on the flexible circuit board 1122 is pushed into the through hole 1111A under the action of external force, the limiting ring 1121A and the second body 1121C form a locking position to achieve a firm connection between the conductive member 1121 and the through hole 1111A, and avoid the conductive member 1121 from falling off under the action of external force after passing through the through hole 1111A, so as to ensure the firm connection between the conductive member 1121 and the housing 111, and further ensure the firm connection between the flexible circuit board 1122 and the housing 111, that is, to ensure the reliability of the ECG acquisition device 1.

[0062] For example, Figure 8As shown, the first body 1121B can be an irregular structure with successively larger diameters, and there is a certain curvature at the transition end between each different diameter to improve the smoothness of pushing the conductive member 1121 into the through hole 1111A under the action of external force, and the limiting ring 1121A can be a limiting member with a certain slope. When the conductive member 1121 is pushed to the limiting ring 1121A, under the action of the slope, the conductive member 1121 can continue to be pushed into the through hole 1111A until the top of the second body 1121C of the conductive member 1121 abuts against the second surface of the shell 111, indicating that the conductive member 1121 has been pushed to the preset position, and even if the conductive member 1121 continues to be pushed with force, the conductive member 1121 cannot continue to move forward. At this time, the limiting ring 1121A abuts against one side of the third protrusion 1111, the first body 1121B is partially located in the through hole 1111A, and the top of the second body 1121C abuts against the second surface of the shell 111. Since the limiting ring 1121A has a slope at this time, that is, the outer diameter of the bottom wall of the limiting ring 1121A in contact with one side of the third protrusion 1111 is larger, the limiting ring 1121A at this time limits the first body 1121B in the through hole 1111A. At the same time, the top of the second body 1121C abuts against the second surface of the shell 111, and the conductive part 1121 cannot be pulled out or pushed forward under the action of external force. In this way, part of the first body 1121B is limited in the through hole 1111A, thereby achieving a firm connection between the conductive part 1121 and the shell 111, and avoiding the problem of the conductive part 1121 falling off under the action of external force after passing through the through hole 1111A.

[0063] For example, the first body 1121B may include a plurality of cylinders with successively larger diameters, the diameter of the first cylinder is 1mm, a semicircle may be provided on the top of the first cylinder, the diameter of the second cylinder is 1.48mm, and the transition end between the second cylinder and the first cylinder has a certain curvature, the diameter of the third cylinder is 1.50mm, and the stop ring 1121A may be the transition end between the second cylinder and the third cylinder, that is, the stop ring 1121A is located on the side wall of the second cylinder close to the third cylinder. The second body 1121C may include a fourth cylinder with a diameter of 1.80mm, one end of the fourth cylinder is connected to the bottom end of the third cylinder, and the transition end between the fourth cylinder and the third cylinder does not need to be provided with a certain curvature, so that the second surface of the shell 111 will abut against the top of the fourth cylinder, so that it cannot be pushed down any further, so that the stop ring 1121A and the fourth cylinder form a locking position. The size and shape of the limiting ring 1121A, the first body 1121B, and the second body 1121C can be set according to actual needs, and this application does not make any specific restrictions on this.

[0064] Optional, such as Fig. 9As shown, the through hole 1111A provided on the third protrusion 1111 can be an annular hole, the annular hole is recessed on the shell 111, and the aperture of the annular hole can be set to a successively increasing aperture to adapt to the shape of the conductive part 1121. This application does not make any specific restrictions on this.

[0065] In summary, the shell 111 in the connection component 11 can be fixedly connected with the collection component 112, wherein the conductive structure 1123 in the collection component 112 is fixed on the wearable component 2, and the third connection part 1122A provided on the flexible circuit board 1122 can be fixedly connected with the shell 111 and the conductive structure 1123, and the multiple conductive members 1121 provided on the flexible circuit board 1122 can not only realize signal transmission, but also realize accurate alignment connection and fixation between the flexible circuit board 1122 and the shell 111, avoiding the problem of alignment difficulty between the flexible circuit board 1122 and the shell 111 when suturing and fixing. In this way, the fixed connection between the shell 111 and the collection component 112 can be realized by double fixation, avoiding the problem of separation between the two under the action of external force. Moreover, the connection component 11 in the present application has strong compatibility and high versatility, and can be applied to be fixed on different types of wearable components 2.

[0066] In order to realize the detachable connection between the connection component 11 and the controller 12, in one example, Fig.10 As shown, the controller 12 is provided with a first protrusion 121 and a receiving area 12A adjacent to the first protrusion 121, two second protrusions 1112 are provided on the second surface of the shell 111, and the two second protrusions 1112 are correspondingly arranged to form a limiting area 1112A, the first protrusion 121 is located in the limiting area 1112A, and one end of a plurality of conductive members 1211 abuts against the receiving area 12A to send an electrical signal to the receiving area 12A, that is, the plurality of conductive members 1211 will transmit vital signs signals such as electrocardiogram information to the controller 12.

[0067] like Fig.11 The figure shows the structure of the controller 12 under different viewing angles. When the first protrusion 121 is located in the limiting area 1112A, the outer wall of the first protrusion 121 abuts against one side of the two second protrusions 1112 respectively, that is, two second protrusions 1112 are provided on the second surface of the shell 111 to form a limiting track. The controller 12 can insert the first protrusion 121 into the limiting track and then push it forward so that the first protrusion 121 is located in the limiting area 1112A. In this way, the problem of inaccurate alignment, which causes the receiving area 12A and the conductive member 1121 to be unable to contact each other and affects the transmission of electrical signals, is avoided.

[0068] In order to limit the path of the first protrusion 121 in the limiting area 1112A, the side wall of the first protrusion 121 will abut against the side wall of the third protrusion 1111, and at this time, the recessed receiving area 12A will abut against the multiple conductive parts 1121 protruding from the raised third protrusion 1111. In this way, while realizing electrical transmission between the receiving area 12A and the conductive parts 1121, the third protrusion 1111 will limit the path of the first protrusion 121 in the limiting area 1112A.

[0069] In order to further improve the connection firmness between the connection assembly 11 and the controller 12, one of the first protrusion 121 and the housing 111 is provided with a buckle groove, and the other of the two is provided with a buckle, which is snapped into the buckle groove to achieve a fixed connection between the two. For example, Fig.10 As shown, two buckles 122 are provided on the first protruding portion 121, and two buckle grooves 1113 are provided on the housing 111 at the position where the buckle 122 is provided on the first protruding portion 121. When the first protruding portion 121 is in the limiting area 1112A, the two buckles 122 are snapped into the buckle grooves 1113 one by one, thereby improving the connection firmness between the connecting component 11 and the controller 12. It is worth noting that buckle grooves can be provided on the first protruding portion 121, buckles can be provided on the housing 111, and other fixing structures can be used, and this application does not make specific restrictions on this.

[0070] Optionally, the shape and size of the controller 12 and the housing 111 can be set to the same structure, or different structures can be adopted, and this application does not make any specific restrictions on this.

[0071] Optionally, the receiving area 12A may be provided with a plurality of receiving contacts to abut against the plurality of conductive members 1121 to receive the electrocardiographic signals transmitted by the conductive members 1121 .

[0072] The controller 12 provided in the present application may be integrated with an ECG acquisition circuit, a single-chip microcomputer (Micro Control Unit, MCU) and other processing circuits. The ECG signal of the conductive element 1121 is received by the ECG acquisition circuit and then sent to the MCU for processing. The MCU transmits the processed signal to the client wirelessly. The client processes the signal and generates a waveform display to display the detection result. Alternatively, the MCU may directly process the ECG signal to generate a corresponding indicator, and then send the indicator to the client for direct display by the client. The present application does not impose any specific restrictions on this.

[0073] In summary, the present application sets the connection component 11 and the controller 12 as a detachable structure, so that the wearable device using the ECG acquisition device 1 can meet the requirements of cleaning and drying, wherein, by setting the conductive member 1121 on the connection component 11, the controller 12 can obtain ECG information through the conductive member 1121 to ensure the collection reliability of the ECG acquisition device 1. Moreover, the collection component 112 in the connection component 11 is a universal structure, that is, it can be fixed to various types of wearable items 2 to collect ECG information. For example, when the wearable item 2 is an ECG detection sticker or an ECG detection belt, the second side of the collection component 112 can be fixed to the wearable item 2 by pasting; when the wearable item 2 is an ECG detection garment, the second side of the collection component 112 can be fixed to the wearable item 2 by stitching. In this way, the collection component 112 can be fixed to any type of wearable item 2 without changing its structure, and has strong versatility and high fixing flexibility. At the same time, the connection component 11 and the controller 12 are detachable structures, so the controller 12 can also be suitable for the use requirements of any wearable item. For example, assuming that the wearable item 2 is a structure that does not need to be cleaned, such as an ECG detection sticker or an ECG detection belt, the connection component 11 and the controller 12 can always maintain a fixed connection to collect ECG information; when the wearable item 2 is a structure that needs to be cleaned, such as an ECG detection shirt, the controller 12 can be removed to meet the cleaning requirements. In this way, the connection component 11 and the controller 12 are set to a general structure with strong compatibility, so that the ECG acquisition device 1 can be fixed on any wearable item 2 to form a wearable device.
