Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical devices, and in particular, to a patch for continuously monitoring physiological signals and a physiological monitoring device. Background Art
[0002] In some medical scenarios, it is necessary to collect and monitor physiological signals of the human body in real time. The existing methods for collecting physiological signals mainly involve fixing a patch structure containing conductive gel at corresponding positions on the human body. For example, a sticky material and the stickiness of the conductive gel itself are used to adhere the patch to the surface of the human skin, thereby realizing the monitoring of physiological signals.
[0003] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely explaining the technical solutions of this application and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of this application. Summary of the Utility Model
[0004] In the existing patch structures, the conductive gel and other structures of the patch are mostly stacked layer by layer. The inventor found that the stability of this structure connected to the human body is relatively poor. For example, in the case of human movement or long-term use of the patch, some structures of the patch (such as the conductive gel) may slip, thereby introducing artifacts and further affecting the quality of the monitoring signal.
[0005] Moreover, the effective use time of the patch with the above structure is relatively short, usually not exceeding 24 hours or not exceeding 42 hours, and it is not suitable for long-term continuous monitoring. For example, when the patch is applied to an instrument for monitoring arrhythmia events such as atrial fibrillation, in the case of long-term use of the patch or when approaching its corresponding effective use time, the moisture evaporated from the human body surface will be absorbed by the conductive gel or other fixing structures of the patch, resulting in a decrease in the stickiness of the patch. The patch may fall off the human body, thereby causing the monitoring process to be interrupted, which is not conducive to the continuous monitoring of physiological signals.
[0006] In addition, after the patch slips or falls off, it is necessary to re-fix the patch or replace it with a new one, which will affect the efficiency of physiological signal monitoring; and frequently moving the patch is likely to further reduce the stability of the patch connection, and frequently replacing the patch is also likely to cause waste.
[0007] To solve at least one of the above problems or other similar problems, the embodiments of this application provide a patch for continuously monitoring physiological signals and a physiological monitoring device.
[0008] According to the first aspect of the embodiments of the present application, a patch for continuously monitoring physiological signals is provided. The patch includes a skin connection layer, an electrical connection layer, and a main connection layer arranged in sequence along a first direction.
[0009] Wherein, the skin connection layer has an opening.
[0010] The electrical connection layer has a conductive gel and an electrode. The first part of the conductive gel is disposed between the skin connection layer and the main connection layer, and the second part of the conductive gel is exposed through the opening to collect electrical signals; the electrode transmits the electrical signals.
[0011] In the first direction, the projected area of the main connection layer is larger than the projected areas of the skin connection layer and the electrical connection layer, and the projected area of the second part of the conductive gel is smaller than the projected area of the opening.
[0012] In some embodiments, the opening is a first through-hole penetrating the skin connection layer.
[0013] In some embodiments, the projections of the first through-hole and the conductive gel in the first direction are both circular, and the diameter of the conductive gel is larger than the diameter of the first through-hole.
[0014] The second part of the conductive gel has a second through-hole.
[0015] In some embodiments, the projection of the first through-hole in the first direction is circular.
[0016] In at least one second direction perpendicular to the first direction, the length of the conductive gel is greater than the diameter of the first through-hole, and in at least one third direction perpendicular to the first direction and different from the second direction, the length of the conductive gel is less than the diameter of the first through-hole.
[0017] In some embodiments, the projection of the conductive gel in the first direction is circular.
[0018] In at least one second direction perpendicular to the first direction, the length of the first through-hole is less than the diameter of the conductive gel, and in at least one third direction perpendicular to the first direction and different from the second direction, the length of the first through-hole is greater than the diameter of the conductive gel.
[0019] In some embodiments, the opening has an open edge.
[0020] In some embodiments, the area of the first part of the conductive gel accounts for 10% - 20% of the total area of the conductive gel.
[0021] In some embodiments, in the first direction, the larger projected area of the skin connection layer and the electrical connection layer does not exceed 40% of the projected area of the main connection layer.
[0022] In some embodiments, the skin connection layer is made of a moisture-absorbing and breathable material.
[0023] According to a second aspect of the embodiments of the present application, there is provided a physiological monitoring device, which includes any one of the patches for continuously monitoring physiological signals provided by the embodiments of the present application.
[0024] One of the beneficial effects of the embodiments of the present application is that by disposing the first part of the conductive gel between the skin connection layer and the main connection layer of the patch, the conductive gel can be fixed, reducing the possibility of the conductive gel slipping or falling off during use, which is beneficial to improving the quality and stability of physiological signal monitoring and the stability of patch connection, and prolonging the service life of the patch; at the same time, the second part of the conductive gel is exposed through the opening provided in the skin connection layer and can directly contact the skin of the human body, thus not affecting physiological signal acquisition.
[0025] Moreover, the projected area of the second part of the conductive gel exposed through the opening of the skin connection layer in the first direction is smaller than the projected area of the opening in the first direction. Thus, a certain space can be reserved for the expansion of the conductive gel, such as the case where the conductive gel expands due to absorbing the moisture evaporated from the human body surface, thereby avoiding the conductive gel becoming non-conforming due to expansion and affecting the quality of the monitoring signal, which is beneficial to improving the quality and stability of physiological signal monitoring.
[0026] Moreover, the projected area of the main connection layer in the first direction is larger than the projected area of the skin connection layer and the projected area of the electrical connection layer in the first direction. Thus, by fixing the patch through the skin connection layer and further strengthening it through the main connection layer, the stability of the patch connection to the skin can be effectively improved, which is further beneficial to prolonging the service life of the patch and is applicable to the scenario of long-term continuous monitoring.
[0027] In addition, through the patch for continuously monitoring physiological signals of the present application, the connection stability between the patch and the human body is improved, so that it is not necessary to frequently adjust the patch position or replace the patch, which is beneficial to improving the efficiency of physiological signal monitoring and can also avoid waste of the patch.

[0042] The following describes the implementation manners of the embodiments of the present application with reference to the accompanying drawings.
[0043] Embodiments of the first aspect
[0044] The embodiments of the first aspect of the present application provide a patch for continuously monitoring physiological signals.
[0045] Figure 1 is a schematic diagram of a component of a patch (hereinafter simply referred to as "patch") for continuously monitoring physiological signals in the embodiments of the present application. Figure 2 is along Figure 1 A top perspective view of the patch after assembling each component along the first direction X shown. As Figure 1 and Figure 2 shown, the patch includes a skin connection layer 1, an electrical connection layer 2, and a main connection layer 3 arranged in sequence along the first direction X. Figure 2 In, the first direction X is the direction perpendicular to the paper surface and into the paper.
[0046] Among them, the skin connection layer 1 has at least one opening 11, and the skin connection layer 1 is used to connect and fix to the skin of the human body. For example, it can be adhered to the skin surface through a sticky material (adhesive), etc. to achieve the fixed connection between the patch and the human body.
[0047] The electrical connection layer 2 has a conductive gel 21 and an electrode 22. Among them, the conductive gel 21 includes two parts, and its first part 211 (see Figure 2 ) is arranged between the skin connection layer 1 and the main connection layer 3, so that the position of the conductive gel 21 can be fixed through the skin connection layer 1 and the main connection layer 3. The second part 212 of the conductive gel 21 (see Figure 2)Exposed through the opening 11 of the skin connection layer 1. Thus, the second part 212 of the conductive gel 21 that is exposed is in direct contact with the human skin through the opening 11 to collect physiological signals of the human body, such as electrical signals. And, in the first direction X, the projected area of the second part 212 of the conductive gel 21 exposed through the opening 11 is smaller than the projected area of the opening 11. Thus, a certain stretching space can be reserved for the conductive gel.
[0048] The electrode 22 includes a first end 221 (see Figure 2 ), a second end 222 (see Figure 2 ), and a connecting component 223 that connects the first end 221 and the second end 222 (see Figure 2 ). Among them, the first end 221 is connected to the surface of the conductive gel 21 on the side close to the main connection layer 3, the second end 222 and the connecting component 223 are fixed between the skin connection layer 1 and the main connection layer 3, and the first end 221 and the second end 222 of the electrode 22 do not overlap in the first direction X. The electrode 22 can be connected to an external device (such as a device for displaying, analyzing, etc. the physiological signals, not shown in the figure) by a wired connection method or a wireless connection method, so as to realize the connection between the patch and the external device, and further transmit the physiological signals collected by the patch to the above external device for display, analysis, etc. processing.
[0049] The projected area of the main connection layer 3 in the first direction X is larger than the projected areas of the skin connection layer 1 and the electrical connection layer 2. For example, as Figure 2 shown, in the first direction X, the projection of the main connection layer 3 covers the projections of the skin connection layer 1 and the electrical connection layer 2. Thus, while being fixedly connected to the human skin through the skin connection layer 1, the part of the main connection layer 3 that extends beyond the skin connection layer 1 can also be fixedly connected to the human skin through an adhesive material, thereby improving the stability of the connection between the patch and the human body.
[0050] Thus, by arranging the first part of the conductive gel between the skin connection layer and the main connection layer of the patch, the conductive gel can be fixed, reducing the possibility of the conductive gel slipping or falling off during use, which is beneficial to improving the quality and stability of physiological signal monitoring and the stability of the patch connection, and extending the service life of the patch; at the same time, the second part of the conductive gel is exposed through the opening provided in the skin connection layer and can be in direct contact with the human skin, thus not affecting the collection of physiological signals.
[0051] Moreover, the projected area of the second part of the conductive gel exposed through the opening of the skin connection layer in the first direction is smaller than the projected area of the opening in the first direction. Thus, a space can be reserved for the expansion of the conductive gel. For example, in the case where the conductive gel expands due to absorbing the moisture evaporated from the human body surface, it can avoid the problem that the conductive gel becomes non-conforming due to expansion and affects the quality of the monitoring signal, which is beneficial to improving the quality and stability of physiological signal monitoring.
[0052] Moreover, the projected area of the main connection layer in the first direction is larger than the projected area of the skin connection layer and the projected area of the electrical connection layer in the first direction. Thus, by fixing the patch through the skin connection layer and further strengthening it through the main connection layer, the stability of the connection between the patch and the skin can be effectively improved, which is further beneficial to extending the service time of the patch and is applicable to the scenario of long-term continuous monitoring.
[0053] In addition, through the patch for continuously monitoring physiological signals of the present application, the connection stability between the patch and the human body is improved, so that there is no need to frequently adjust the position of the patch or replace the patch, which is beneficial to improving the efficiency of physiological signal monitoring and can also avoid the waste of patches.
[0054] It should be noted that in the embodiments of the present application, the skin connection layer 1 is described by taking it including two openings 11 as an example, but the present application is not limited thereto. In practical applications, one or more openings can be set according to requirements. The number of the conductive gel 21 and the electrodes 22 included in the electrical connection layer 2 respectively corresponds to the number of the openings 11 on the skin connection layer 1. The embodiments of the present application also take the number of both the conductive gel 21 and the electrodes 22 being 2 as an example for illustration, but the present application is not limited to this. The position of the conductive gel 21 corresponds to the position of the opening 11 in the skin connection layer 1 and can be set according to actual requirements, and the present application does not limit this. The sizes of the opening 11 and the conductive gel 21 can be set according to actual application scenarios as needed, and the present application does not limit this.
[0055] In some embodiments, as Figure 2 shown, in the first direction X, except for the second part 212 of the conductive gel 21, the remaining components of the electrical connection layer 2 are all arranged between the skin connection layer 1 and the main connection layer 3. Thus, each component of the electrical connection layer 2 can be better fixed.
[0056] In some embodiments, from the perspective of the first direction X, the shape of the opening 11 can be any shape, such as circular, elliptical, rectangular, etc.
[0057] In some embodiments, from the perspective of the first direction X, the shape of the conductive gel 21 can be any shape, such as circular, elliptical, annular, rectangular, etc.
[0058] Embodiments of the opening 11 and the conductive gel 21 with different shapes will be described below with several examples.
[0059] In some embodiments, the opening 11 of the skin connection layer 1 is a first through-hole penetrating the skin connection layer 1.
[0060] In some embodiments, the projection of the first through-hole 12 in the first direction X is circular; and in at least one second direction perpendicular to the first direction X, the length of the conductive gel 21 is greater than the diameter of the first through-hole 12, and in at least one third direction perpendicular to the first direction X and different from the second direction, the length of the conductive gel 21 is less than the diameter of the first through-hole 12.
[0061] For example, Figure 3 is a top view of a patch according to an embodiment of the present application. As Figure 3 shown, in the first direction X, the first through-hole 12 is circular with a diameter of d1, the conductive gel 21 is elliptical, and the major axis a1 of the ellipse is greater than the diameter d1 of the first through-hole 12, and the minor axis b1 of the ellipse is less than the diameter d1 of the first through-hole 12. Thus, at least in the major axis direction (corresponding to the second direction), the length of the conductive gel 21 is greater than the diameter of the first through-hole 12, and at least in the minor axis direction (corresponding to the third direction), the length of the conductive gel 21 is less than the diameter of the first through-hole 12.
[0062] Again, for example, Figure 4 is another top view of a patch according to an embodiment of the present application. As Figure 4 shown, in the first direction X, the first through-hole 12 is circular with a diameter of d2, the conductive gel 21 is rectangular, and the length a2 of the rectangle is greater than the diameter d2 of the first through-hole 12, and the width b2 of the rectangle is less than the diameter d2 of the first through-hole 12. Thus, at least in the length direction (corresponding to the second direction), the length of the conductive gel 21 is greater than the diameter of the first through-hole 12, and at least in the width direction (corresponding to the third direction), the length of the conductive gel 21 is less than the diameter of the first through-hole 12.
[0063] Thus, as Figure 3 and Figure 4 shown, in the first through-hole 12, a certain expansion space 13 is reserved for the conductive gel 21. During the use of the patch, if the conductive gel 21 absorbs the moisture evaporated by the human body, it can expand into the expansion space 13, thereby preventing the conductive gel 21 from becoming non-conforming due to expansion and affecting the quality of the monitoring signal, which is beneficial to improving the quality and stability of physiological signal monitoring.
[0064] In addition, in addition to Figure 3 and Figure 4In addition to what is shown, when the first through hole 12 is circular, the conductive gel 21 can also be any other shape, as long as the first part of the conductive gel 21 can be arranged between the skin connection layer 1 and the main connection layer 3, and there is an expansion space 13 for the conductive gel 21 to expand in the first through hole 12.
[0065] In some embodiments, the projection of the conductive gel 21 in the first direction X is circular; in at least one second direction perpendicular to the first direction X, the length of the first through hole 12 is less than the diameter of the conductive gel 21, and in at least one third direction perpendicular to the first direction X and different from the second direction, the length of the first through hole 12 is greater than the diameter of the conductive gel 21.
[0066] For example, Figure 5 is another top view of the patch according to the embodiment of the present application. As Figure 5 shown, in the first direction X, the conductive gel 21 is circular with a diameter of d3, the first through hole 12 is an ellipse, and the major axis a3 of the ellipse is greater than the diameter d3 of the conductive gel 21, and the minor axis b3 of the ellipse is less than the diameter d3 of the conductive gel 21. Thus, at least in the major axis direction (corresponding to the second direction), the length of the first through hole 12 is greater than the diameter of the conductive gel 21, and at least in the minor axis direction (corresponding to the third direction), the length of the first through hole 12 is less than the diameter of the conductive gel 21.
[0067] Another example is Figure 6 is another top view of the patch according to the embodiment of the present application. As Figure 6 shown, in the first direction X, the conductive gel 21 is circular with a diameter of d4, the first through hole 12 is rectangular, and the length a4 of the rectangle is greater than the diameter d4 of the conductive gel 21, and the width b4 of the rectangle is less than the diameter d4 of the conductive gel 21. Thus, at least in the length direction (corresponding to the second direction), the length of the first through hole 12 is greater than the diameter of the conductive gel 21, and at least in the width direction (corresponding to the third direction), the length of the first through hole 12 is less than the diameter of the conductive gel 21.
[0068] Therefore, as Figure 5 and Figure 6 shown, in the first through hole 12, a certain expansion space 13 is reserved for the conductive gel 21. During the use of the patch, if the conductive gel 21 absorbs the moisture evaporated by the human body, it can expand into the expansion space 13, thereby preventing the conductive gel 21 from becoming non-adherent due to expansion and affecting the quality of the monitoring signal, which is beneficial to improving the quality and stability of physiological signal monitoring.
[0069] In addition, in addition to Figure 5 and Figure 6In addition to what is shown, when the conductive gel 21 is circular, the first through hole 12 can also be of any other shape, as long as the first part of the conductive gel 21 can be arranged between the skin connection layer 1 and the main connection layer 3, and there is an expansion space 13 in the first through hole 12 for the conductive gel 21 to expand.
[0070] In some embodiments, the projections of the first through hole 12 and the conductive gel 21 in the first direction X are both circular, and the diameter of the conductive gel 21 is greater than the diameter of the first through hole 12; and a second through hole is provided on the second part 212 of the conductive gel 21. Wherein, the projected area of the second through hole in the first direction X is smaller than the projected area of the second part 212 of the conductive gel 21.
[0071] For example, Figure 7 is another top view of the patch according to the embodiment of the present application. As Figure 7 shown, in the first direction X, the first through hole 12 is circular with a diameter of d5; the conductive gel 21 is also circular with a diameter of d6, where the diameter d6 of the conductive gel 21 is greater than the diameter d5 of the first through hole 12; and a second through hole 213 is further provided on the second part 212 of the conductive gel 21 exposed through the first through hole 12, and the projected area of the second through hole 213 in the first direction X is smaller than the projected area of the second part 212 of the conductive gel 21.
[0072] At this time, the second through hole 213 serves as the expansion space 13 reserved for the conductive gel 21. During the use of the patch, if the conductive gel 21 absorbs the moisture evaporated by the human body, it can expand into the second through hole 213, thereby preventing the conductive gel 21 from becoming non-conforming due to expansion and affecting the quality of the monitoring signal, which is beneficial to improving the quality and stability of physiological signal monitoring.
[0073] It should be noted that Figure 7 in, the first through hole 12, the conductive gel 21, and the second through hole 213 are all circular and coaxially arranged, but the present application is not limited thereto. In practical applications, the second through hole 213 can be provided at any position on the second part 212 of the conductive gel 21, and the shape of the second through hole 213 can be of any shape.
[0074] In some embodiments, the opening 11 of the skin connection layer 1 has an open edge.
[0075] For example, as Figure 2As shown, the opening 11 is provided at the edge of the skin connection layer 1, and the opening 11 has an open edge, that is, the opening 11 is not in a closed shape. Thus, after the second part 212 of the conductive gel 21 absorbs the moisture evaporated by the human body, it can expand towards the open edge of the opening 11 and even exceed the range of the opening 11. Therefore, the space for the conductive gel 21 to absorb moisture and expand is increased, which is beneficial to improving the quality and stability of physiological signal monitoring.
[0076] In some embodiments, the shape of the opening 11 with an open edge and its position on the skin connection layer 1 may be different from Figure 2 , and the present application does not limit this.
[0077] In order to further improve the stability of the patch connected to the human body, extend the effective use time of the patch, and improve the use effect of the patch, the present application further defines the dimensions, materials, etc. of the components of the patch for continuously monitoring physiological signals.
[0078] In some embodiments, the area of the first part 211 of the conductive gel 21 accounts for 10% - 20% of the total area of the conductive gel.
[0079] That is, 10% - 20% of the total area of the conductive gel 21 is disposed between the skin connection layer 1 and the main connection layer 3. At this time, a better fixing effect can be achieved on the conductive gel 21.
[0080] In some embodiments, the size of the second part 212 of the conductive gel 21 ranges from 5 mm to 10 mm. For example, Figures 2 to 7 in, the value ranges of the maximum size and the minimum size of the second part 212 of the conductive gel 21 are both 5 mm to 10 mm. Thus, the size of the second part 212 of the conductive gel 21 in contact with the human body is controlled to avoid affecting the accuracy of the collected physiological signals.
[0081] In some embodiments, the unilateral difference between the second part 212 of the conductive gel 21 and the opening 11 does not exceed 2 mm. For example, Figure 3 in, in the short axis direction of the conductive gel 21, the difference between the size b1 of the second part 212 of the conductive gel 21 and the size d1 of the opening 11 is 2 mm or less than 2 mm, and at the same time, this difference is also greater than 0. Another example, Figure 5 in, in the long axis direction of the opening 11, the difference between the size d3 of the second part 212 of the conductive gel 21 and the size a3 of the opening 11 is 2 mm or less than 2 mm, and at the same time, this difference is also greater than 0. Another example, in Figure 7 in, the diameter of the second through hole 213 is 2 mm or less than 2 mm, and at the same time, this diameter is greater than 0.
[0082] In some embodiments, in the first direction X, the larger projected area of the skin connection layer 1 and the electrical connection layer 2 does not exceed 40% of the projected area of the main connection layer 3. Thus, the main connection layer can have a relatively large adhesion force, which can better reinforce the connection between the patch and the human body, and is beneficial to further improving the stability of the connection between the patch and the human body.
[0083] In some embodiments, in the first direction X, the distance between the edge of the projection of the main connection layer 3 and the edge of the one with the larger projected area among the skin connection layer 1 and the electrical connection layer 2 is not less than 7 mm. Thus, it can better reinforce the connection between the patch and the human body, and is beneficial to further improving the stability of the connection between the patch and the human body.
[0084] In some embodiments, the skin connection layer and the main connection layer are made of moisture-absorbing and breathable materials, such as non-woven fabrics. Thus, it is beneficial to discharge the moisture evaporated by the human body, reduce the moisture absorption and expansion of the conductive gel, and avoid the conductive gel exceeding the reserved expansion space; at the same time, it can also reduce the moisture absorbed by the skin connection layer, slow down the reduction rate of the adhesiveness of the adhesive on the skin connection layer and the main connection layer, and extend the service time of the patch.
[0085] In some embodiments, the thickness of the skin connection layer is not too thick, for example, it is 1 mm. Thus, it is convenient for the second part of the conductive gel to contact the human body through the opening.
[0086] Through the above embodiments, the patch for continuously monitoring physiological signals of the present application arranges the first part of the conductive gel between the skin connection layer and the main connection layer of the patch, which can fix the conductive gel, reduce the possibility of the conductive gel slipping or falling off during use, and thus is beneficial to improving the quality and stability of physiological signal monitoring and the stability of patch connection, and extending the service time of the patch; at the same time, the second part of the conductive gel is exposed through the opening provided in the skin connection layer and can directly contact the skin of the human body, so that it will not affect physiological signal acquisition.
[0087] Moreover, the projected area of the second part of the conductive gel exposed through the opening of the skin connection layer in the first direction is smaller than the projected area of the opening in the first direction. Thus, a space can be reserved for the expansion of the conductive gel, such as the case where the conductive gel expands due to absorbing the moisture evaporated from the human body surface, so as to avoid the conductive gel becoming non-conforming due to expansion and affecting the quality of the monitoring signal, and is beneficial to improving the quality and stability of physiological signal monitoring.
[0088] Moreover, the projected area of the main connection layer in the first direction is larger than the projected areas of the skin connection layer and the electrical connection layer in the first direction. Thus, by fixing the patch through the skin connection layer and further strengthening it through the main connection layer, the stability of the connection between the patch and the skin can be effectively improved, which is conducive to extending the service time of the patch and is applicable to scenarios of long-term continuous monitoring.
[0089] In addition, through the patch for continuously monitoring physiological signals of the present application, the connection stability between the patch and the human body is improved, so that there is no need to frequently adjust the position of the patch or replace the patch, which is conducive to improving the efficiency of physiological signal monitoring and can also avoid waste of the patch.
[0090] Embodiments of the second aspect
[0091] Embodiments of the second aspect of the present application provide a physiological monitoring device, which includes any one of the patches for continuously monitoring physiological signals provided by the embodiments of the first aspect of the present application.
[0092] In some embodiments, the physiological monitoring device further includes at least one external device, which is connected to the above-mentioned patch through a wired connection method or a wireless connection method, and receives the physiological signals detected by the patch through the wired connection method or the wireless connection method. The external device includes, for example, but is not limited to, a device for performing at least one of the processes of displaying, analyzing, etc. on the received physiological signals.
[0093] In some embodiments, the wired connection method includes, for example, but is not limited to, connecting through a signal transmission line; the wireless connection method includes, for example, but is not limited to, connecting through Bluetooth, WiFi, zigbee, 2G / 3G / 4G / 5G / 6G, and various future wireless communication methods.
[0094] In some embodiments, the physiological monitoring device includes, for example, but is not limited to, a device for monitoring electrocardiogram signals, electroencephalogram signals, or other physiological signals. For example, the physiological monitoring device is an electrocardiograph, an electrocardiogram monitor, etc. for monitoring electrocardiogram signals.
[0095] For the patch used in the above-mentioned physiological monitoring device, by disposing the first part of the conductive gel between the skin connection layer and the main connection layer of the patch, the conductive gel can be fixed, reducing the possibility of the conductive gel slipping or falling off during use, which is conducive to improving the quality and stability of physiological signal monitoring and the connection stability of the patch, and extending the service time of the patch; at the same time, the second part of the conductive gel is exposed through the opening provided in the skin connection layer and can be in direct contact with the human skin, thus not affecting physiological signal acquisition.
[0096] Moreover, the projected area in the first direction of the second part of the conductive gel exposed through the opening of the skin connection layer is smaller than the projected area of the opening in the first direction. Thus, a space can be reserved for the expansion of the conductive gel. For example, in the case where the conductive gel expands due to absorbing the moisture evaporated from the human body surface, it can avoid the influence on the quality of the monitoring signal caused by the non-conformity of the conductive gel due to expansion, which is beneficial to improving the quality and stability of physiological signal monitoring.
[0097] Moreover, the projected area of the main connection layer in the first direction is larger than the projected area of the skin connection layer and the projected area of the electrical connection layer in the first direction. Thus, by fixing the patch through the skin connection layer and further strengthening it through the main connection layer, the stability of the connection between the patch and the skin can be effectively improved. Furthermore, it is beneficial to extend the service time of the patch and is applicable to the scenario of long-term continuous monitoring.
[0098] In addition, through the patch for continuously monitoring physiological signals of the present application, the connection stability between the patch and the human body is improved. Thus, there is no need to frequently adjust the position of the patch or replace the patch, which is beneficial to improving the efficiency of physiological signal monitoring and can also avoid the waste of the patch.
