[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The core of the present invention is to provide an electrocardiogram acquisition device with good applicability.

[0048] It should be noted that when an element is referred to as "fixing" another element, it can be directly on another element or there can also be a centered element. When an element is considered to be "connected" to another element, it can be directly connected to another element or there may be a centered element at the same time. The orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third", "fourth", "fifth", and "sixth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, unless otherwise specified, "electrically connected" refers to a circuit connection in physical contact.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0050] In a specific embodiment of the electrocardiogram acquisition device provided by the present invention, it includes a host 1, a wearing structure and external electrodes.

[0051] The host 1 is provided with a host signal acquisition device 11 and a host electrode 12, and the host electrode 12 is electrically connected to the host signal acquisition device 11. Specifically, Figure 1Therefore, the host 1 includes a housing, a host signal acquisition device 11 disposed in the housing, and a mainboard 19 disposed in the housing. Functional modules such as a power management module 111, a filter amplifier module, an AD conversion, a CPU, and a communication module 110 are disposed on the mainboard 19. The host signal acquisition device 11 filters and amplifies the received electrode signal by the filter amplifier module, and then sends it to the CPU for processing. The CPU sends the processing result to the communication module 110, which transmits it to other devices. The communication module 110 is specifically a wireless communication module. In addition, a button 18 is disposed on the housing to control the opening and closing and function switching of the host 1.

[0052] The wearing structure is provided with an intermediate connection circuit 4, and the external electrode includes a chest conduction electrode 6 fixed to the wearing structure, one end of the intermediate connection circuit 4 is electrically connected to the chest conduction electrode 6 and the other end is detachably electrically connected to the host signal acquisition device 11. The number of chest conduction electrodes 6 is usually at least two, and different chest conduction electrodes 6 can be used in any combination.

[0053] The host 1 is detachably connected to the wearing structure, and the wearing structure and the chest lead electrode 6 can be fixed to the human body. Specifically, the chest lead electrode 6 can be fixed to the human body through the wearing structure, and the chest lead electrode 6 is not provided with a connection structure to directly connect to the human body. After the wearing structure is fixed to the human body, the chest lead electrode 6 is pressed against the human body by the wearing structure to achieve the fixation of the chest lead electrode 6 and the human body; or, the chest lead electrode 6 can also be directly provided with a connection structure to directly connect to the human body.

[0054] The host signal acquisition device 11 switches the output information according to the signal strength of the received chest conduction electrode 6. When the signal strength of at least one chest conduction electrode 6 received by the host signal acquisition device 11 is greater than the preset strength threshold, the host 1 outputs the electrode information collected by the external electrode but does not output the electrode information collected by the host electrode 12; otherwise, the host 1 outputs the electrode information collected by the host electrode 12 but does not output the electrode information collected by the external electrode. Specifically, the preset strength threshold can be set to 0V, that is, when the received signal voltage is greater than 0V, it indicates that the chest conduction electrode 6 is in the working state of electrocardiogram detection, otherwise, the chest conduction electrode 6 is in the non-working state.

[0055] The host 1 is detachably connected to the wearing structure, and has two states: connected and detached. The host can automatically determine whether the host 1 is connected to the wearing structure based on the signal strength of the chest conduction electrode 6. When the host signal acquisition device 11 determines that the signal strength of at least one chest conduction electrode 6 is greater than the preset strength threshold, it is determined that the external electrode is in a working state, the host 1 is connected to the wearing structure, and the electrocardiogram acquisition device is in an integrated working mode. At this time, the information collected by the external electrode is valid electrocardiogram information, and the host 1 outputs the electrocardiogram signal of the external electrode; when the host signal acquisition device 11 determines that the signal strength of all chest conduction electrodes 6 is not greater than the preset strength threshold, it is determined that the external electrode is not in a working state, the host 1 is separated from the wearing structure, and the electrocardiogram acquisition device is in a host independent working mode. At this time, the information collected by the host electrode 12 is valid electrocardiogram information, and the host 1 outputs the electrocardiogram signal of the host electrode 12.

[0056] It can be seen that in the electrocardiogram acquisition device provided in this embodiment, the host 1 is detachable relative to the wearing structure, and the host 1 can use the host electrode 12 thereon to collect the electrocardiogram alone, which is suitable for short-term electrocardiogram detection. The host 1 can also be connected to the wearing structure, and the wearing structure and the external electrode are connected to the human body. The electrocardiogram is collected using the external electrode, which is suitable for long-term continuous electrocardiogram detection, thereby improving the applicability of the electrocardiogram acquisition device. In addition, the host 1 can judge whether the external electrode is put into use based on the signal strength of the chest lead electrode 6, thereby judging the connection status between the host 1 and the wearing structure and the working status of the electrocardiogram acquisition device, and output the information collected by the working electrode based on the judgment result, which can ensure the accuracy of the output electrocardiogram result.

[0057] For further information, please refer to Figure 3 , the external electrode also includes a lead-out electrode 7. The lead-out electrode 7 is connected to the wearing structure through a lead wire 71, and the lead wire 71 electrically connects the lead-out electrode 7 to the intermediate connection circuit 4. The detection position of the lead-out electrode 7 is relatively flexible, which can improve the flexibility of ECG detection. An adhesive layer can be specifically provided on the lead-out electrode 7 to be bonded and fixed to the human body. Among them, the lead wire 71 can be specifically connected to the wearing structure in an undetachable manner, or it can be detachably connected to the wearing structure, so as to facilitate the separate storage of the wearing structure and the lead-out electrode 7, and convenient storage.

[0058] Of course, in other embodiments, the lead-out electrode 7 may not be directly connected to the wearing structure. For example, in another embodiment, the lead-out electrode 7 is connected to the host 1 through a lead wire 71, and the lead wire 71 electrically connects the lead-out electrode 7 to the host signal acquisition device 11. At this time, preferably, the lead wire 71 is detachably connected to the host 1. Specifically, an interface is provided at the free end of the lead wire 71, which is plugged into the corresponding interface on the host 1 through the interface, so that the lead wire 71 is mechanically connected to the host 1 while the electrical connection between the two is achieved through the interface. Through the detachable connection, the unused lead-out electrode 7 and the lead wire 71 can be removed when the electrocardiogram acquisition device is in the host independent working mode, thereby reducing the weight of the host 1.

[0059] For further information, please refer to Figure 3 The external electrode also includes a right leg driving electrode 8 fixed on the wearing structure, the right leg driving electrode 8 is electrically connected to the intermediate connecting circuit 4, and the right leg driving electrode 8 can be fixed to the human body. The right leg driving electrode 8 is used in conjunction with the chest conduction electrode 6, and when the electrocardiogram acquisition device is in the integrated working mode for detection, a clean, stable, and undistorted graphic effect can be obtained.

[0060] For further information, please refer to Figure 3 The wearing mechanism specifically includes a chest strap 3 for binding to the human body, and has good wearing reliability.

[0061] Furthermore, if Fig.14 As shown, the chest strap 3 includes a belt body 33, and the intermediate connection circuit 4 is built in the belt body 33. At least one of the chest conduction electrode 6 and the right leg driving electrode 8 is sewn and fixed to the belt body 33 through the flexible conductive electrode connecting sewing thread 36, and is electrically connected to the intermediate connection circuit 4 through the flexible conductive electrode connecting sewing thread 36, that is, the flexible conductive electrode connecting sewing thread 36 can realize the electrical connection between the electrode and the intermediate connection circuit 4 while realizing the fixation of the electrode to the belt body 33, which facilitates the assembly operation of the chest conduction electrode 6 and the right leg driving electrode 8 on the belt body 33, and the connection reliability is good.

[0062] Specifically, the belt body 33 includes a belt body surface layer 34 and a belt body outer layer 35, and the intermediate connection circuit 4 is sandwiched between the belt body surface layer 34 and the belt body outer layer 35 to form a circuit layer built into the belt body 33. The two ends of the belt body 33 can be specifically provided with matching fixing structures such as Velcro or hooks. After the belt body 33 is wrapped around the chest with the side where the chest conduction electrode 6 and the right leg driving electrode 8 are provided on the belt body 33 facing the human body, the belt body 33 is fixed to the human body through the fixing structure. After the belt body 33 is fixed to the human body, the chest conduction electrode 6 and the right leg driving electrode 8 are fixed to the human body along with the belt body 33. Preferably, the belt body 33 is a waterproof elastic fabric to extend the service life of the belt body 33. More specifically, if Figure 3As shown, the middle part of the belt body 33 in the length direction is a flexible electrode belt 31, and the two ends are elastic belts 32. The host 1, the intermediate connecting circuit 4, the chest conduction electrode 6, and the right leg driving electrode 8 can all be set on the flexible electrode belt 31.

[0063] Specifically, the chest conduction electrode 6 includes an outer conductive layer 6, a hot melt adhesive film 62, and an elastic filling body 63 fixed between the outer conductive layer 6 and the hot melt adhesive film 62. Optionally, the elastic filling body 63 is cylindrical, elliptical, or square, and the chest conduction electrode 6 is fixed to the belt body surface layer 34 through the hot melt adhesive film 62. In addition, the outer conductive layer 6 is sutured and fixed to the belt body 33 and the intermediate connection circuit 4 through the flexible conductive electrode connection sewing thread 36. Obviously, the right leg driving electrode 8 can also be arranged in the same manner as the chest conduction electrode 6.

[0064] Furthermore, if Figure 3 As shown, at least six chest conduction electrodes 6 are arranged on the same surface of the wearing structure, specifically only 6 electrodes, including electrode B1, electrode B2, electrode B3, electrode B4, electrode B5, and electrode B6. There are at least three lead-out electrodes 7, specifically only 3 electrodes, including a first lead-out electrode A1, a second lead-out electrode A2, and a third lead-out electrode A3. In addition, one right leg driving electrode 8 is arranged, specifically the first right leg driving electrode C1.

[0065] When the electrocardiogram acquisition device is in the integrated working mode for detection, the chest strap 3 is attached to a specific position on the chest, and the first lead-out electrode A1, the second lead-out electrode A2, and the third lead-out electrode A3 are respectively attached to the left and right clavicle edges and the left lower abdomen of the body. At this time, the host 1 can automatically collect the signals of each external electrode, corresponding to the electrocardiogram signals of the left and right upper limbs, left and right legs, and chest leads defined in medicine, thereby obtaining a dynamic electrocardiogram of international standard Ⅰ, Ⅱ, Ⅲ, aVL, aVR, aVF, V1, V2, V3, V4, V5, and V6 leads (up to 12 leads).

[0066] In addition, before using the wearing structure, a wearing structure of a corresponding type can be selected according to the height and chest circumference of the user, so that the position error of each chest lead electrode 6 can meet the clinical medical requirements.

[0067] Furthermore, if Figures 4 to 8 As shown, host electrodes 12 are fixed on at least two surfaces of the host 1. For example, host electrodes 12 are respectively arranged on two opposite surfaces or two adjacent surfaces of the host 1, so as to perform ECG detection at different positions through the host 1.

[0068] More specifically, a first host electrode a1 and a second host electrode a2 are arranged on one surface of the host 1, and a third host electrode a3 is arranged on the opposite side of the surface. When the electrocardiogram acquisition device is in the host independent working mode for detection, the first host electrode a1 and the second host electrode a2 are touched by the left and right hands at the same time, and the third host electrode a3 is closely attached to the surface of the left lower abdomen or the left leg, so that the host 1 can automatically acquire standard limb lead electrocardiograms, including leads Ⅰ, Ⅱ, Ⅲ, aVL, aVR, and aVF.

[0069] Furthermore, the host 1 is provided with a host connector 13 electrically connected to the host signal acquisition device 11, and the wearing structure is provided with a mating connector 5 electrically connected to the intermediate connection circuit 4. The host connector 13 is electrically connected to the mating connector 5 to electrically conduct the host signal acquisition device 11 and the intermediate connection circuit 4, and the host connector 13 and the mating connector 5 are detachably fixedly connected through a magnetic attraction structure. Of course, in other embodiments, the magnetic attraction structure can also be replaced by a buckle structure, a lace structure, or an adhesive structure.

[0070] Specifically, Fig. 9 As shown, the host connector 13 and the mating connector 5 are electrically connected through the basic structure of the connector such as the spring pin 16 and the circuit board 15, so that the intermediate connection circuit 4 and the host signal acquisition device 11 are electrically connected through the host connector 13 and the mating connector 5. In addition, a host magnet group 14 is provided on the host connector 13, and a mating magnet group 52 is provided on the mating connector 5. The host magnet group 14 and the mating magnet group 52 are magnetically matched to guide, position and fix the host connector 13 and the mating connector 5 when connected, so as to realize quick disassembly and assembly.

[0071] In addition, in order to further improve the installation efficiency of the host connector 13 and the mating connector 5, optionally, the mating connector 5 is fixed to the fixed disk 53 through a wearing structure, and a guide column 51 is fixed on the fixed disk 53. Correspondingly, a guide groove is provided on the host connector 13. When the host connector 13 and the mating connector 5 are connected, the guide groove is correspondingly sleeved on the guide column 51, and the guide groove and the guide column 51 cooperate to guide.

[0072] The working principle of the electrocardiogram acquisition device provided in this embodiment is as follows: the host signal acquisition device 11 automatically determines the strength of the electrode signal of the chest conduction electrode 6. If there is an electrode signal of the chest conduction electrode 6 that is greater than the preset intensity threshold, the host determines that the current working state is an integrated working mode; if the electrode signal of each chest conduction electrode 6 is not greater than the preset intensity threshold, the host determines that the current working state is a host independent working mode. In the integrated working mode, the host 1 and the chest strap 3 are connected together for use, and the host reads and outputs the electrode signals of the lead-out electrode, the chest conduction electrode, and the right leg drive electrode, and does not read or output the electrode signal of the host electrode 12. In the host independent working mode, the host is used alone, and the host does not read or output the electrode signals of the lead-out electrode, the chest conduction electrode, and the right leg drive electrode, and only reads and outputs the electrode signal of the host electrode 12.

[0073] Obviously, in another specific embodiment, the wearing structure is not limited to being set as the chest strap 3 in the above embodiment. Optionally, the wearing structure includes a chest patch 2 for being attached to the human body, which is easy to remove from the human body. The chest patch 2 is made of a flexible plastic material, such as silicone rubber, and is embedded with an intermediate connection circuit 4 inside, which is a flexible circuit board. In addition, the surface of the chest patch 2 has an adhesive alignment mark 21, which uses the body midline and the nipple as the positioning reference, so that the user can operate it by himself.

[0074] Furthermore, if Fig.10 and Fig.11 As shown, a chest conduction electrode 6, a right leg driving electrode 8 and an adhesive structure 23 are arranged side by side on one side of the chest patch 2, and the chest conduction electrode 6, the right leg driving electrode 8 and the adhesive structure 23 do not overlap each other on the chest patch 2. Optionally, the adhesive structure 23 is specifically a disposable double-sided adhesive layer, one side of which is attached to the chest patch 2 and the other side is attached to the body, and a hollow position 22 is provided on the adhesive structure 23, and the chest conduction electrode 6 or the right leg driving electrode 8 is installed in the hollow position 22.

[0075] Alternatively, in another embodiment, the chest conduction electrode 6 and the right leg driving electrode 8 may also be directly bonded to the human body. Fig.12 and Fig.13 As shown, the chest conduction electrode 6 is a self-adhesive electrode patch, and the chest conduction electrode 6 is fixed to the chest patch 2 through a conductive female buckle and electrically connected to the intermediate connection circuit 4 through the conductive female buckle. Optionally, the conductive female buckle includes a conductive adhesive layer 24, a conductive connection male buckle 25 and a support layer 26, and the conductive adhesive layer 24 and the conductive connection male buckle 25 are both electrically connected and fixed on the support layer 26, wherein the conductive connection male buckle 25 is used to be fixedly connected to the conductive connection female buckle on the intermediate connection circuit 4 and electrically connected at the same time, and the chest conduction electrode 6 is fixed on the conductive adhesive layer 24. Of course, the right leg driving electrode 8 can be set in the same way as the above chest conduction electrode 6.

[0076] In this embodiment, the chest conduction electrode 6 and the right leg driving electrode 8 are adhesively fixed to the human body, which is easy to operate. The chest conduction electrode 6 and the right leg driving electrode 8 are buckled and fixed to the chest patch, so that the used chest conduction electrode 6 and the right leg driving electrode 8 can be quickly replaced.

[0077] Obviously, in another specific embodiment, the wearing structure and the host 1 can also be connected together in an inseparable manner. In this case, it is necessary to ensure that each host electrode on the host is exposed and not covered by the wearing structure. Since in the above embodiment, when the host is used alone, that is, when the electrocardiogram acquisition device is in the host independent working mode, the wearing structure can be removed to avoid the external electrodes being accidentally contacted and changing the working mode of the electrocardiogram acquisition device, the above detachable embodiment is a more preferred solution.

[0078] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0079] The electrocardiogram acquisition device provided by the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
