Description

Technical Field

[0001] This invention relates to the field of electrocardiogram (ECG) sensor technology, specifically a transmission circuit for a dynamic ECG recorder sensor. Background Technology

[0002] Traditional Holter monitoring devices are a commonly used non-invasive examination method in the diagnosis of clinical cardiovascular diseases. They use electrodes fixed to the patient's chest and a wearable recorder to record the patient's electrocardiogram signals for 24 hours or longer in daily life, and can effectively capture paroxysmal arrhythmias.

[0003] However, existing Holter monitoring devices contain a large number of ferromagnetic metal elements, such as the metal leads of the electrode pads and the electronic components in the recorder. As a result, MRI and CT scans are usually prohibited when patients are wearing Holter monitoring devices. Furthermore, the multiple leads on the chest can also affect echocardiography. If a patient experiences acute chest pain or suspected aortic dissection during Holter monitoring and requires MRI, CT, or echocardiography, the Holter device must be removed first, and the electrodes must be reattached after the examination. This significantly impacts both the examination and ECG monitoring. Summary of the Invention

[0004] The purpose of this invention is to provide a transmission circuit for a dynamic electrocardiogram recorder sensor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A transmission circuit for a dynamic electrocardiogram (ECG) recorder sensor includes a base layer with two surfaces: a back surface and a detection surface. The back surface and detection surface are disposed on the base layer. The base layer includes a collection block, which is fixedly mounted on a base. A main unit is detachably mounted on the base. The collection block is provided with several detection branches, each with several circular acquisition points. Several lines 1 are printed on the back surface of the base layer, and several lines 2 are printed on the detection surface of the base layer. Both lines 1 and lines 2 have a layered structure. One end of each line 1 and line 2 extends to a corresponding circular acquisition point, and the other end of each line 1 and line 2 extends to the collection block.

[0007] Furthermore, the detection surface at the grassroots level has several detection points printed on the corresponding circular collection point. One end of line 2 is fixedly connected to the adjacent detection point, and the circular collection point at the corresponding end of line 1 has a through hole. The one end of line 1 and the adjacent detection point are interconnected through the through hole.

[0008] The back of the base layer is provided with several connection points. The other end of line one is connected to the adjacent connection point. The collecting block is provided with several connecting holes at the other end of line two. The other end of line two is connected to the adjacent connection point through the corresponding connecting holes.

[0009] Furthermore, the two detection branches located at the top of the base layer are the first branches. A circular collection point is set at the end of the first branch away from the collection block. One end of the line on the first branch is connected to the adjacent detection point, and the other end extends to the collection block.

[0010] Preferably, the two detection branches located at the bottom of the base layer are the second branch and the third branch, respectively. The end of the second branch away from the collection block is provided with several circular collection points, and the third branch is provided with several circular collection points. One end of the line on the second branch and the third branch is connected to the adjacent detection point, and the other end extends to the collection block.

[0011] Furthermore, the third branch has several forks at the end furthest from the collection block, and several circular collection points are set on the forks. Line 1 is printed on the third branch and the forks. One end of Line 1 is connected to the detection point on the corresponding fork through a through hole, and the other end of Line 1 extends to the collection block through the third branch.

[0012] Preferably, the width of the third branch near the end of the collection block is less than 5mm.

[0013] Furthermore, the materials used for the connection point, Line 1, and Line 2 are all silver paste.

[0014] Preferably, the material used for the detection point is silver chloride.

[0015] Preferably, the width of both Line 1 and Line 2 is less than 1 mm, and the thickness of both Line 1, Line 2 and the detection point is less than 0.04 mm.

[0016] Preferably, the base material is PET.

[0017] Preferably, insulating oil layers are provided on both sides of the base layer, and the insulating oil layers are used to cover line one and line two.

[0018] Preferably, the base is made of plastic, and the base has several through holes corresponding to several conductive points. Several locking blocks are set inside the base, and the main unit has several slots that engage with adjacent locking blocks.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Several lines 1 and several lines 2 are printed on the back and detection side of the base layer, respectively. During ECG monitoring with the wearable Holter monitor, if MRI or CT scans are required, the main unit can be detached from the base. The patient can continue the examination while wearing the Holter monitor with the sensor connected. Only the transmission circuit on the sensor has a metallic magnetic material, and the continuity points, lines 1 and 2 are printed on the base layer. The thickness of the metal circuits such as the continuity points and lines 1 and 2 is relatively thin. Therefore, during the detection process, the transmission circuit has minimal impact on the imaging of MRI and CT scans, thus meeting the requirements. To meet the requirements of MRI and CT examinations, the main unit is reinstalled after the examination to continue ECG monitoring. Since the electrodes do not need to be removed, ECG monitoring is only briefly interrupted during the examination, which helps to reduce the impact on ECG monitoring. At the same time, in order to avoid affecting the echocardiogram examination, when wearing the device, the collection block can be attached to the right side of the chest, exposing the left side of the heart, while all detection branches are close to the patient's body surface. There are no additional leads affecting the movement of the ultrasound probe, so that the electrodes do not need to be removed during MRI, CT, and echocardiogram examinations, which is conducive to the smooth conduct of examinations and ECG monitoring.

[0021] 2. By printing Line 1 on the third branch and fork, for the third branch with a large number of detection points, Line 1 is printed on the back of the third branch, and some Line 2 is printed on the detection surface of the third branch. This ensures that the back and detection surfaces of the third branch have a maximum of three Line 1 or three Line 2 lines running in parallel at the same time. This helps to reduce the width of the third branch, with the widest part of the third branch not exceeding 5mm. This balances the increase in the width of the third branch caused by the thinness of Line 1 and Line 2, thereby reducing the discomfort of patients when wearing it. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-7 In this embodiment of the invention, a transmission circuit for a dynamic electrocardiogram recorder sensor includes a base layer 10. The base layer 10 has two surfaces, namely a back surface and a detection surface. The back surface and the detection surface are provided on the base layer 10. The base layer 10 includes a collection block 11. A base support 50 is fixedly provided on the collection block 11. A main unit 60 is detachably provided on the base support 50. The base support 50 is made of plastic. A plurality of card blocks 52 are provided inside the base support 50. The main unit 60 has a plurality of card slots 61 that engage with adjacent card blocks 52.

[0032] The collection block 11 is provided with several detection branches, and several circular collection points 15 are provided on the detection branches. Several lines 1 20 are printed on the back of the base layer 10, and several lines 2 30 are printed on the detection surface of the base layer 10. Both lines 1 20 and lines 2 30 are layered structures. One end of both lines 1 20 and lines 2 30 extends to the corresponding circular collection point 15, and the other end of both lines 1 20 and lines 2 30 extends to the collection block 11.

[0033] The base layer 10 has several detection points 40 printed on the detection surface corresponding to the circular acquisition points 15. One end of the second line 30 is fixedly connected to the adjacent detection point 40. A through hole is opened on the circular acquisition point 15 corresponding to one end of the first line 20. One end of the first line 20 and the adjacent detection point 40 are interconnected through the through hole. Several connection points 16 are provided on the back of the base layer 10. The bottom support 50 has several through holes corresponding to the several connection points 16. The other end of the first line 20 is connected to the adjacent connection point 16. The collecting block 11 corresponds to the other end of the second line 30. Several connecting holes are provided at one end. The other end of line 2 30 is connected to the adjacent connecting point 16 through the corresponding connecting holes. Several collection points 15 correspond one-to-one with several detection points 40. One end of each line 1 20 and line 2 30 corresponds to a detection point 40, and the other end of each line 1 20 and each line 2 30 corresponds to a connecting point 16. Each connecting point 16 is connected to the corresponding detection point 40 through line 1 20 or line 2 30, so that several detection points 40 are connected to several connecting points 16 one-to-one.

[0034] Specifically, an electrode structure 70 is provided on the sampling point 15. The electrode structure 70 includes hydrogel and two layers of non-woven fabric. The hydrogel is attached to the detection point 40 on the sampling point 15. The two layers of non-woven fabric are bonded to each other, and the two sides of the non-woven fabric are respectively bonded to the back side and the detection surface of the base layer 10. The sampling point 15 is located between the two layers of non-woven fabric. A round hole is provided in the middle of the non-woven fabric on the detection surface of the base layer 10. The detection point 40 and the hydrogel are located in the round hole of the non-woven fabric.

[0035] The electrode structure 70 is also equipped with a protective layer and a release film. During the monitoring process, the protective layer is used to separate the non-woven fabric from the clothing, and the release film is used to isolate the hydrogel from the outside world during storage, thus protecting the hydrogel.

[0036] The connection point 16 is located on the back of the collection block 11. The main unit 60 has several metal spring needles. The main unit 60 is fastened to the base 50. After the base 50 limits the main unit 60 through the locking block 52 and the locking slot 61, the metal spring needles will pass through the corresponding holes and abut against the adjacent connection point 16 to conduct. After peeling off the release film on the electrode structure 70, the non-woven fabric can be glued to the patient's skin. The hydrogel can contact the patient's skin. The detection surface of the base layer 10 will correspond to the patient's skin, while the back of the base layer 10 will face the patient's clothes. The detection point 40 can collect the electrocardiogram signal through the hydrogel. The detection point 40 can transmit the electrocardiogram signal to the connection point 16 through the corresponding line 1 20 or line 2 30. That is, the electrocardiogram signals collected by several detection points 40 are collected one by one to several connection points 16 on 11 through line 1 20 and line 2 30, and then transmitted to the main unit 60 through the metal spring needles, so that the main unit 60 can continuously collect the electrocardiogram signal through the electrocardiogram sensor.

[0037] The base 50 has a protruding edge 51, which facilitates bending the base 50 to disengage the locking block 52 on one side of the base 50 from the locking slot 61, thereby removing the main unit 60 from the base 50. During ECG monitoring with the wearable dynamic ECG recorder, if an MRI or CT scan is required, the main unit 60 can be removed from the base 50 in the above manner. At this point, only the conduction point 16, line 1 20, line 2 30, and detection point 40 of the ECG sensor remaining on the patient's body are made of metal; the rest of the sensor is made of non-metallic materials. The conduction point 16, line 1 20, line 2 30, and detection point 40 are all printed onto the base. The layered structure on layer 10 has relatively thin conductors 16, line 1 20, and line 2 30. At the same time, the detection point 40 covers one end of line 1 20 or line 2 30, and the detection point 40 is relatively thin. This way, when the patient is wearing the sensor of the dynamic electrocardiogram recorder, the transmission circuit has little impact on the imaging of MRI, CT and other examinations, which can meet the requirements of MRI and CT examinations. In order to avoid affecting the echocardiogram examination, when wearing the recorder, the collection block 11 can be attached to the right side of the chest away from the heart, exposing the left side of the heart. After the examination is completed, the main unit 60 is re-snapped into the base 50 to continue the electrocardiogram monitoring.

[0038] Since there is no need to remove the electrodes and the main unit 60 is easy to assemble and disassemble, the time spent disassembling the main unit 60 before and after the examination is short. Only a brief interruption of ECG monitoring is required during the examination, which helps to reduce the impact on ECG monitoring. In addition, all the detection branches are in close contact with the patient's body surface, and there are no additional leads that affect the movement of the ultrasound probe. Therefore, it is not necessary to remove the electrodes during MRI, CT and echocardiography examinations, which is conducive to the smooth conduct of examinations and ECG monitoring.

[0039] Example 1

[0040] like Figure 2-4 As shown, in this embodiment, the materials of the conductive point 16, line 1 20, and line 2 30 are all silver paste, the material of the detection point 40 is silver chloride, the material of the base layer 10 is PET, the width of line 1 20 and line 2 30 is less than 1mm, and the thickness of line 1 20, line 2 30 and detection point 40 is less than 0.04mm.

[0041] In specific implementation, during the production process, silver paste is first printed on the PET substrate 10 to form line 20 and line 30. Conductive points 16 are printed on the back of the collection block 11. Then, silver chloride is placed on the detection surface of several collection points 15 of the substrate 10. Silver chloride is covered on one end of line 30 so that line 30 is connected to the adjacent detection point 40. One end of line 20 is connected to the adjacent detection point 40 through the through hole. When silver chloride comes into contact with hydrogel, it has good ECG signal transmission performance.

[0042] The thickness of the superimposed lines 1 (20) and 2 (30) does not exceed 0.08 mm. After multiple MRI and CT examinations, the silver paste circuit and silver chloride dots have a low impact on the imaging and basically do not affect the analysis and judgment of the images.

[0043] like Figure 1-3 As shown, in this embodiment, the two detection branches located at the top of the base layer 10 are the first branch 12. The end of the first branch 12 away from the collection block 11 is provided with a circular collection point 15. One end of the line 30 on the first branch 12 is connected to the adjacent detection point 40, and the other end extends to the collection block 11.

[0044] The two detection branches located at the bottom of the base layer 10 are the second branch 13 and the third branch 14. The end of the second branch 13 away from the collection block 11 is provided with several circular collection points 15. The third branch 14 is provided with several circular collection points 15. One end of the second line 30 on the second branch 13 and the third branch 14 is connected to the adjacent detection point 40, and the other end extends to the collection block 11. The end of the third branch 14 away from the collection block 11 is provided with several branches 141. The branches 141 are provided with several circular collection points 15. The first line 20 is printed on the third branch 14 and the branches 141. The width of the end of the third branch 14 near the collection block 11 is less than 5mm. One end of the first line 20 is connected to the detection point 40 on the corresponding branch 141 through a through hole, and the other end of the first line 20 extends to the collection block 11 through the third branch 14. The first line 20 is located on the back of the third branch 14, while several second lines 30 are located on the detection surfaces of the first branch 12, the second branch 13, and the third branch 14.

[0045] In practice, by setting up a second branch 13, a third branch 14, and two first branches 12, and setting up multiple detection points 40 on them, the ECG monitoring of twelve leads is simulated to obtain more detailed ECG monitoring data. In the radiofrequency pyrography test of MRI, heat is generated only at the detection point 40 located on the bifurcation 141 that is furthest from the converging block 11, and its maximum temperature rise does not exceed 4.37 degrees Celsius, which is within the acceptable range for the human body.

[0046] Meanwhile, for the third branch 14, which has a large number of detection points 40, by printing line 1 20 on the back of the third branch 14 to transmit the ECG data collected by the detection points 40 on the two branches 141, and printing part of line 2 30 on the detection surface of the third branch 14 to transmit the ECG data collected by the detection points 40 on the main trunk of the third branch 14, the back and detection surfaces of the third branch 14 each have only three lines 1 20 or three lines 2 30 running in parallel at the same time. This helps to reduce the width of the main trunk of the third branch 14. The widest width of the main trunk of the third branch 14 near the collector block 11 does not exceed 5mm, thereby balancing the increase in width of the third branch 14 caused by the thinness of line 1 20 and line 2 30, which helps to reduce the discomfort of patients when wearing it.

[0047] Example 2

[0048] Based on Example 1, such as Figure 2 and Figure 3 As shown, in this embodiment, insulating oil layers are provided on both sides of the base layer 10, and the insulating oil layers are used to cover line one 20 and line two 30.

[0049] In practice, the insulating oil layer is used to insulate and cover the first line 20 and the second line 30, thus protecting them. Since the electrode structure 70 is set at the detection point 40, in order to ensure the transmission of the electrocardiogram signal, the insulating oil layer is hollowed out at the detection point 40 and will not cover the detection point 40, nor will it cover the conduction point 16.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
