[0033] 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.
[0034] The embodiment of the present application provides an ECG acquisition device, which is essentially a wearable ECG acquisition device that can be used in various environments such as companies, schools, homes, factories, hospitals, etc. to collect electrical signals of the heart.
[0035] Please combine Figure 1 and Figure 2 , the ECG acquisition device provided by the present invention is now described. The ECG acquisition device includes a binding member 10, a collection unit 20, a first electrode member 30, a first conductive member, a shielding member 40, a second electrode member 50, a third electrode member 60 and a fourth electrode member 70. Among them, the binding member 10 is used to be bound and fixed to the human body. The collection unit 20 is arranged on the binding member 10. The first electrode member 30 is used to electrically connect with the skin at the second intercostal space on the right edge of the chest of the human body to collect the electrical signal of the heart at the above position. The first conductive member is used to electrically connect the collection unit 20 with the first electrode member 30 to transmit the electrical signal collected by the first electrode member 30 to the collection unit 20. Since the electrical signal collection position of the first electrode member 30 is far from the position of the binding member 10, the first conductive member can ensure that the first electrode member 30 and the binding member 10 can be in a preset position. Further, the shielding member 40 is at least partially sleeved on the first conductive member to be able to be electrically connected to the skin of the human body, and the shielding member 40 can be grounded through the collection unit 20. The second electrode 50 is provided on the binding member 10 and electrically connected to the collection unit 20, so as to be electrically connected to the skin at the apex beat point of the human body after the binding member 10 is fixedly bound to the human body, so as to collect the electrical signal of the heart at the above position and transmit it to the collection unit 20. The third electrode 60 is provided on the binding member 10 and electrically connected to the collection unit 20, so as to be symmetrically provided with the second electrode 50 on the front and back sides of the human body after the binding member 10 is fixedly bound to the human body, and the third electrode 60 is electrically connected to the skin of the human body, so as to collect the electrical signal of the heart at the above position and transmit it to the collection unit 20. The fourth electrode 70 is provided on the binding member 10 and electrically connected to the collection unit 20, so as to be symmetrically provided with the second electrode 50 on the left and right sides of the human body after the binding member 10 is fixedly bound to the human body, and the fourth electrode 70 is electrically connected to the skin of the human body, so as to collect the electrical signal of the heart at the above position and transmit it to the collection unit 20. Figure 1 The position of the third electrode member 60 in the figure is not the final position where the third electrode member 60 is in contact with the skin, and it is only to indicate that the third electrode member 60 needs to be arranged around the back of the human body.
[0036] In summary, the implementation of the embodiment of the present invention will have the following beneficial effects: the ECG acquisition device of the above scheme includes a binding member 10, which can be tied and fixed to the human body by virtue of its own elasticity, and can improve the connection stability and the comfort of the human body. Further, the ECG acquisition device also includes an acquisition unit 20, a first electrode member 30, a first conductive member, a shielding member 40, a second electrode member 50, a third electrode member 60 and a fourth electrode member 70, and the first electrode member 30, the second electrode member 50, the third electrode member 60 and the fourth electrode member 70 respectively correspond to the electrical signal acquisition position of the human body and transmit the collected electrical signal data to the acquisition unit 20, and the acquisition unit 20 can store, analyze and transmit the above electrical signal data. Among them, the fourth electrode member 70 is used as a reference electrode member, which is symmetrically arranged on the left and right sides of the human body with the second electrode member 50 to facilitate the arrangement of the electrode members on the binding member 10. The setting of the shielding member 40 can absorb the static electricity on the first electrode member 30 through the grounding of the acquisition unit 20, thereby avoiding static electricity from interfering with the above-mentioned electrical signal acquisition, so that the collected electrical signal data is sufficiently accurate. The RL / N electrode (reference electrode) is used to reduce the power frequency interference of the human body. The ECG signal of the human body is very small, usually only a few microvolts (one ten-thousandth of a volt). The human body is equivalent to an antenna, which can easily receive 50Hz alternating current electromagnetic interference (commonly known as "power frequency interference"). The power frequency interference will mask the weak ECG signal of the human body, making the ECG waveform unrecognizable. Therefore, the RL / N electrode is introduced. The RL / N electrode combined with the right leg drive circuit of the electrocardiograph can effectively eliminate the power frequency interference and improve the quality of the ECG waveform.
[0037] In one embodiment, Figure 6As shown, the shielding member 40 includes a sleeve portion 41 and an embedded portion 42, and the sleeve portion 41 is sleeved on the first conductive member to isolate the circumference of the first conductive member from the outside world. That is, the sleeve portion 41 can form a tubular structure, and the first conductive member is accommodated in the sleeve portion 41 as a whole, and only the two ends can be electrically connected to the first electrode member 30 and the collection unit 20 respectively, so as to be able to transmit the electrical signal data collected by the first electrode member 30 to the collection unit 20. Further, the sleeve portion 41 is electrically connected to the human skin and can be grounded through the collection unit 20, and the embedded portion 42 is embedded in the binding member 10 and can be grounded through the collection unit 20. The embedded portion 42 can absorb the static electricity on the binding member 10 through the grounding of the collection unit 20 to avoid static electricity from interfering with the collected electrical signal. In this embodiment, the first electrode member 30 is an electrode sheet. One end of the first conductive member can form a snap-on structure so that it can be snapped and electrically connected to the first electrode member 30. At the same time, the above-mentioned card connection is a detachable connection, which is convenient for replacing the first electrode member 30 during use to prevent cross infection between different subjects. Further, the first conductive member is a lead wire, including a core and an insulating kit located circumferentially of the core, and the insulating kit can electrically isolate the first conductive member from the shielding member 40. The core and the shielding member 40 are made of the same material. Further, the acquisition unit 20 is an electrocardiograph, which can continuously and uninterruptedly monitor the electrocardiograph function of the subject through the cardiac electrical signals collected by the first electrode member 30, the second electrode member 50, the third electrode member 60 and the fourth electrode member 70. In this embodiment, the acquisition unit 20 adds a grounding terminal on the basis of the above-mentioned electrocardiograph to facilitate the grounding and absorption of static electricity transmitted from the shielding member 40 to the acquisition unit 20. At the same time, the acquisition unit 20 can also transmit the electrical signal data to the mobile phone and computer terminal through wifi, Bluetooth, etc., so as to facilitate real-time viewing of the electrocardiograph function of the subject, thereby facilitating and effectively completing the data collection and analysis of the electrocardiogram, greatly reducing the workload of the doctor.
[0038] In one embodiment, Figure 3 , Figure 5 and Figure 6As shown, the ECG acquisition device also includes a first conductive end 31, a second conductive end 51, a third conductive end 61, a fourth conductive end 71 and a fifth conductive end 43. The first conductive end 31 is provided on the binding member 10. The first conductive member is electrically connected to the acquisition unit 20 through the first conductive end 31. The second conductive end 51 is provided on the binding member 10. The second electrode member 50 is electrically connected to the acquisition unit 20 through the second conductive end 51. The third conductive end 61 is provided on the binding member 10. The third electrode member 60 is electrically connected to the acquisition unit 20 through the third conductive end 61. The fourth conductive end 71 is provided on the binding member 10. The fourth electrode member 70 is electrically connected to the acquisition unit 20 through the fourth conductive end 71. The fifth conductive end 43 is provided on the binding member 10. The sleeve portion 41 and the embedded portion 42 are respectively grounded through the acquisition unit 20 through the fifth conductive end 43. In this way, the first conductive end 31, the second conductive end 51, the third conductive end 61, the fourth conductive end 71 and the fifth conductive end 43 can facilitate the electrical connection between the first electrode member 30, the second electrode member 50, the third electrode member 60, the fourth electrode member 70 and the shielding member 40 and the collection unit 20, thereby improving the connection stability and isolating the electrical signals from each other before transmitting to the collection unit 20 to avoid interference.
[0039] In one embodiment, a connecting portion is provided on the binding member 10, and a mating portion 21 is provided on the collection unit 20 to be mated with the connecting portion, and the connecting portion and the mating portion 21 are detachably connected. In this way, the connection stability between the collection unit 20 and the binding member 10 can be ensured by the connecting portion. At the same time, the connecting portion and the mating portion 21 are detachably connected, which can ensure that when one of the collection unit 20 and the binding member 10 is damaged, it is convenient to repair and replace the damaged part. At the same time, the collection unit 20 can also be provided with a rechargeable power supply component, which can be removed from the binding member 10 when charging is needed, so as to be conveniently connected to the charging component. Further, Figure 4 As shown, the collection unit 20 is provided with a charging terminal 22, which faces one side of the binding member 10 when the collection unit 20 is connected to the binding member 10 as a whole, so as to prevent external impact on the charging terminal 22 and increase its life.
[0040] In one embodiment, Figure 3 and Figure 4As shown, the number of connecting parts is five, including a first connecting part, a second connecting part, a third connecting part, a fourth connecting part and a fifth connecting part. The first conductive end 31 can form a first connecting part. The second conductive end 51 can form a second connecting part. The third conductive end 61 can form a third connecting part. The fourth conductive end 71 can form a fourth connecting part. The fifth conductive end 43 can form a fifth connecting part. The number of matching parts 21 is consistent with the number of connecting parts and is matched and connected one by one and electrically connected. In this way, the corresponding connecting parts are formed by each conductive end, and each matching part 21 is connected to each matching part 21 while ensuring electrical connection with each matching part 21, so that the conductive end has two functions of fixing and conducting, thereby saving the manufacturing cost. In this embodiment, the first connecting part, the second connecting part, the third connecting part, the fourth connecting part and the fifth connecting part are convex structures, and the matching part 21 matched therewith is a groove structure. It can be understood that in other embodiments, the first connecting part, the second connecting part, the third connecting part, the fourth connecting part and the fifth connecting part are groove structures, and the matching part 21 matched therewith is a convex structure. In this embodiment, four of the first conductive end 31 , the second conductive end 51 , the third conductive end 61 , the fourth conductive end 71 and the fifth conductive end 43 are arranged around another one, thereby ensuring the stability of the connection of the collection unit 20 to the binding member 10 .
[0041] In one embodiment, Figure 5 and Figure 6 As shown, a first extension portion 80 is provided at one end of the first conductive member away from the first electrode member 30. The first extension portion 80 extends from the first conductive member from the sleeve portion 41, and the first conductive member and the first conductive end 31 are electrically connected through the first extension portion 80. A second extension portion 411 is provided at one end of the sleeve portion 41 away from the first electrode member 30. The second extension portion 411 extends from the sleeve portion 41 to a side away from the first conductive member. The sleeve portion 41 and the fifth conductive end 43 are electrically connected through the second extension portion 411. In this way, the first extension portion 80 and the second extension portion 411 are arranged to facilitate electrical connection with the first conductive end 31 and the second conductive end 51, so that the first conductive end 31 and the second conductive end 51 can be spaced at an appropriate distance to achieve electrical isolation.
[0042] In one embodiment, the second electrode member 50, the third electrode member 60 and the fourth electrode member 70 are fabric electrodes or special conductive electrodes soaked with metal powder to ensure that the second electrode member 50, the third electrode member 60 and the fourth electrode member 70 are soft enough to fit the skin. The special form of soaking with metal powder specifically refers to soaking metal powder such as gold powder with relatively low resistance into the cloth. At this time, the gold powder layer with the cloth as the matrix becomes a conductor, which can sense the electrical signals of the human body when in direct contact with the human body, that is, it plays a role in signal collection.
[0043] In one embodiment, Figures 1 to 3 , Figure 5and Figure 6 As shown, the binding member 10 is in the shape of a belt, and the binding member 10 includes a main body 11 and an insulating portion 12.

The first conductive end 31, the second conductive end 51, the third conductive end 61, the fourth conductive end 71 and the fifth conductive end 43 are all at least partially exposed on the main body 11. The first conductive end 31 is electrically connected to the first conductive member through the body 11 and the insulating portion 12 in sequence, the second conductive end 51 is electrically connected to the second electrode member 50 through the body 11 and the insulating portion 12 in sequence, the third conductive end 61 is electrically connected to the third electrode member 60 through the body 11 and the insulating portion 12 in sequence, the fourth conductive end 71 is electrically connected to the fourth electrode member 70 through the body 11 and the insulating portion 12 in sequence, and the fifth conductive end 43 is electrically connected to the sleeve portion 41 and the embedded portion 42 in sequence through the body 11 and the insulating portion 12. That is, the first conductive end 31, the second conductive end 51, the third conductive end 61, the fourth conductive end 71 and the fifth conductive end 43 are all arranged opposite to the insulating portion 12. Further, a plurality of through holes 421 are provided on the embedded portion 42, and the first conductive end 31, the second conductive end 51, the third conductive end 61 and the fourth conductive end 71 are correspondingly penetrated in each through hole 421. In this way, the embedded portion 42 can be spaced apart from the first conductive end 31 , the second conductive end 51 , the third conductive end 61 and the fourth conductive end 71 to achieve electrical isolation.
[0044] In one embodiment, the ECG acquisition device further includes a second conductive member 52, a third conductive member 62 and a fourth conductive member 72.

The second electrode member 50 is electrically connected to the second conductive end 51 through the second conductive member 52, the third electrode member 60 is electrically connected to the third conductive end 61 through the third conductive member 62, and the fourth electrode member 70 is electrically connected to the fourth conductive end 71 through the fourth conductive member 72. In this way, the second electrode member 50, the third electrode member 60 and the fourth electrode member 70 can be arranged on the binding member 10 conveniently by setting the second conductive member 52, the third conductive member 62 and the fourth conductive member 72, so that when the binding member 10 is tied and fixed to the human body, the second electrode member 50, the third electrode member 60 and the fourth electrode member 70 correspond to the acquisition position, thereby ensuring the accuracy of the collected electrical signals.
[0045] Furthermore, if Figure 6As shown, the insulating portion 12 is a multi-layer structure, including a first insulating layer 121, a second insulating layer 122, a third insulating layer 123 and a fourth insulating layer 124. Specifically, the first insulating layer 121 is arranged to fit the bottom of the mounting groove. The embedded portion 42 is embedded between the first insulating layer 121 and the second insulating layer 122. The third insulating layer 123 fits the second insulating layer 122, and is provided with a through groove for accommodating the second conductive member 52, the third conductive member 62 and the fourth conductive member 72. The fourth insulating layer 124 fits the third insulating layer 123 and is located on the outer side of the insulating portion 12 as a whole. The second electrode member 50, the third electrode member 60 and the fourth electrode member 70 penetrate the fourth insulating layer 124 and are electrically connected to the second conductive member 52, the third conductive member 62 and the fourth conductive member 72 respectively.
[0046] In this embodiment, the second conductive member 52 , the third conductive member 62 and the fourth conductive member 72 are made of non-metallic conductive material or metallic conductive material, or are fabric electrodes.
[0047] In this embodiment, Figure 1 and Figure 2 As shown, the collection unit 20 is located in front of the human chest to shorten the distance with the second electrode 50, the third electrode 60 and the fourth electrode 70, reduce the transmission distance of the electric signal, and thus reduce the probability of the electric signal being interfered.
[0048] In one embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the main body 11 has a first free end and a second free end. The first free end is provided with a first annular portion 13. The second free end is provided with a second annular portion 14. The ECG acquisition device also includes a connector 15. The first annular portion 13 and the second annular portion 14 are connected by the connector 15 so that the binding member 10 is bound and fixed to the human body. Specifically, the connector 15 includes a fixed end and a plug-in portion provided on the fixed end, the fixed end can be fixedly connected to one of the first annular portion 13 and the second annular portion 14, and the plug-in portion can be inserted into the other of the first annular portion 13 and the second annular portion 14 to connect the first free end and the second free end so that the binding member 10 is bound and fixed to the human body. In this embodiment, the first annular portion 13 and the second annular portion 14 are made of the same material as the main body 11.
[0049] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5, a first extension section is provided at the first free end. The first extension section extends from the first free end and folds back to be fixedly connected to the main body 11 to form a first annular portion 13.

The second extension portion 411 can be passed between the adjusting member 16 and the main body 11 to fix the adjusting member 16 to the main body 11. In this way, by adjusting the position of the adjusting member 16 on the main body 11, the distance between the adjusting member 16 and the connecting member 15 can be adjusted, thereby adjusting the tightness of the binding member 10 to improve the stability and comfort of the binding member 10 and the human body, reduce the restraint of the existing wearable ECG acquisition equipment on the human body, and make it more convenient to use.
[0050] The existing collection of ECG signals often uses the Nehb three-lead ECG method. The connection method of the Nehb three-lead ECG method is to connect the right-hand electrode of the human body lead to the second intercostal space at the right edge of the sternum, the left lower limb electrode to the apex beat point, the left hand electrode to the posterior axillary line at the level of the apex, and the right lower limb ground electrode remains unchanged. When the lead switch of the acquisition unit 20 is pulled to the I lead, the recorded ECG is the D lead, when it is pulled to the II lead, the recorded ECG is the A lead, and when it is pulled to the III lead, the recorded ECG is the J lead.

[0052] D = I = C2-C1;
[0053] A = II = C3-C1;
[0054] J=Ⅲ=C3-C2.
[0055] In an electrocardiogram acquisition device provided by the present application, the first conductive end 31 is electrically connected to the first electrode member 30 through the first conductive member, so that the first conductive end 31 is electrically connected to the skin at the second intercostal space on the right side of the chest of the human body, which is equivalent to the C1 lead in the Nehb three-lead electrocardiogram method, the second conductive end 51 is electrically connected to the second electrode member 50 through the second conductive member 52, so that the second conductive end 51 is electrically connected to the skin at the apex beat point of the human body, which is equivalent to the C3 lead in the Nehb three-lead electrocardiogram method, and the third conductive end 61 is electrically connected to the third electrode member 60 through the third conductive member 62, so that the third conductive end 61 is electrically connected to the skin of the back of the human body symmetrical to the apex beat point, which is equivalent to the C2 lead in the Nehb three-lead electrocardiogram method. When the lead switch of the acquisition unit 20 is pulled to the I lead, the recorded electrocardiogram is the D lead, when it is pulled to the II lead, the recorded electrocardiogram is the A lead, and when it is pulled to the III lead, the recorded electrocardiogram is the J lead.
