Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wearable equipment, in particular to a fixing patch. Background Art
[0002] Currently, many wearable devices come with adhesive stickers to adhere to the surface of human skin. However, due to the market demand trend for wearable devices, the size needs to be smaller and smaller, so the size of the adhesive stickers on the wearable devices is generally small, so the adhesive force provided by the adhesive stickers on the wearable devices is very limited. As a result, the user may easily experience abnormal situations where the wearable device is detached during wearing, which in turn makes the monitoring or diagnosis of the wearable device ineffective. Therefore, for wearable devices that need to be worn for a long time (such as continuous glucose monitoring systems CGMs), the use of fixed stickers for enhanced fixation is a good solution. The structural advantage is that in addition to reinforcing the edge of the original skin-friendly adhesive sticker of the wearable device, the fixed adhesive sticker can directly fix the wearable device on the skin, making the entire wear more secure and giving users more peace of mind.
[0003] However, the fixing stickers used for secondary fixing in the prior art are basically used to fix the edge of the adhesive stickers of the wearable device, and they do not directly fix the wearable device, and cannot ensure the reliability of the wearable device. In addition, the fixing stickers used for secondary fixing in the prior art cannot meet the wearing requirements of a single person with one hand.
[0004] It should be noted that the information disclosed in the background technology section of the utility model is only intended to deepen the understanding of the general background technology of the utility model, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art. Utility Model Content
[0005] The purpose of the utility model is to provide a fixing sticker, which can not only strengthen the edge of the adhesive sticker of the fixed wearable device, but also cover the wearable device itself, thereby greatly improving the wearing reliability.
[0006] In order to achieve the above object, the utility model provides a fixing patch, which includes an adhesive layer and an isolation layer stacked together;
[0007] The adhesive layer is used to cover the wearable device and includes an adhesive surface for bonding to the skin surface of the user;
[0008] The isolation layer covers at least a portion of the area of the adhesive layer that covers the wearable device, so as to separate the device body of the wearable device from the corresponding area of the adhesive layer when the wearable device is worn.
[0009] Optionally, the isolation layer covers a middle area of the adhesive layer.
[0010] Optionally, the isolation layer includes an electrostatic diaphragm.
[0011] Optionally, the bonding layer includes a flexible waterproof substrate and an adhesive disposed on the lower surface of the flexible waterproof substrate, and the adhesive is distributed on the lower surface of the flexible waterproof substrate to form the bonding surface.
[0012] Optionally, the fixing patch further includes a reinforcing layer, the reinforcing layer is attached to at least the outer edge of the upper surface of the adhesive layer, and the reinforcing layer can be removed under the action of an external force.
[0013] Optionally, the reinforcement layer exposes at least a middle area of the upper surface of the adhesive layer.
[0014] Optionally, the reinforcement layer has at least one slit, and at least one end of the slit extends to the outer edge of the reinforcement layer.
[0015] Optionally, the fixing patch further includes a protective layer stacked below the isolation layer, the protective layer covers the adhesive surface and the isolation layer, and the protective layer can be removed under the action of an external force to expose the adhesive surface and the isolation layer.
[0016] Optionally, the protective layer includes a first sub-protective layer and a second sub-protective layer, the first sub-protective layer covers the adhesive surface and a region on one side of the isolation layer, and the second sub-protective layer covers the adhesive surface and a region on the other side of the isolation layer.
[0017] Optionally, a side region of the first sub-protective layer close to the second sub-protective layer overlaps with a side region of the second sub-protective layer close to the first sub-protective layer to form an interlaced region.
[0018] Compared with the prior art, the fixing patch provided by the utility model has the following beneficial effects:
[0019] The fixing patch provided by the utility model includes a stacked adhesive layer and an isolation layer; the adhesive layer is used to cover the wearable device, and includes an adhesive surface for bonding to the user's skin surface; the isolation layer covers at least a portion of the adhesive layer used to cover the wearable device, so as to separate the device body of the wearable device from the corresponding area of the adhesive layer when worn. Since the adhesive layer in the fixing patch provided by the utility model can cover the entire area of the wearable device, it can not only strengthen the edge of the adhesive patch that fixes the wearable device, but also cover the wearable device itself (i.e., the device body). At the same time, the fixing patch has good overall adhesion, and the adhesive area is large enough to provide sufficient adhesion, thereby greatly improving the reliability of wearing the wearable device. In addition, by providing the isolation layer, the device body of the wearable device can be separated from the adhesive surface of the adhesive layer when strengthening the fixation of the wearable device, thereby ensuring that there is no surface area where the adhesive directly contacts the device body of the wearable device in the area where the isolation layer is located. This not only protects the appearance of the wearable device intact, but also ensures that the user can easily separate the fixing patch from the wearable device during use, so as to more conveniently replace the fixing patch, which is more conducive to the reuse of multiplexed wearable devices (such as multiplexed transmitter-type wearable devices).

The first feature being "below", "below" and "below" the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0037] The core idea of the utility model is to provide a fixing patch that can not only strengthen the edge of the adhesive patch that fixes the wearable device, but also cover the wearable device itself, thereby greatly improving the reliability of wearing. It should be noted that, as can be understood by those skilled in the art, the wearable device referred to in this article can be, but is not limited to, medical wearable devices such as blood sugar monitoring sensor devices, traditional Chinese medicine patches, radiotherapy positioning patches, infusion needle patches, and can also be wearable devices in other fields.
[0038] In order to realize the above idea, the utility model provides a fixing sticker, please refer to Figures 1 to 4 ,in, Figure 1 A schematic diagram of the front structure of a fixing patch provided in one embodiment of the utility model; Figure 2 A schematic diagram of the back structure of a fixing sticker provided in one embodiment of the utility model; Figure 3 A partial cross-sectional view of a fixing patch provided by one embodiment of the utility model along the AA plane; Figure 4This is a schematic diagram of the exploded structure of a fixing sticker provided by one embodiment of the utility model. Figures 1 to 4 As shown, the fixing patch provided by the utility model includes an adhesive layer 110 and an isolation layer 120 which are stacked; the adhesive layer 110 is used to cover the wearable device 200, and includes an adhesive surface (not shown in the figure) for bonding to the user's skin surface; the isolation layer 120 covers at least a portion of the area of the adhesive layer 110 used to cover the wearable device 200, so as to separate the device body 210 of the wearable device 200 from the corresponding area of the adhesive layer 110 when worn.
[0039] Since the adhesive layer 110 in the fixing patch provided by the present invention can cover the entire area of the wearable device 200, it can not only strengthen the adhesive patch 220 (see Figure 5 , which is a schematic diagram of the overall structure of the wearable device 200 provided in one embodiment of the utility model, and can cover the wearable device 200 itself (i.e., the device body 210). At the same time, the overall adhesion of the fixing patch is good, and the bonding area is large enough to provide sufficient bonding force, thereby greatly improving the reliability of wearing the wearable device 200. In addition, by providing the isolation layer 120, when strengthening the fixation of the wearable device 200, the device body 210 of the wearable device 200 can be separated from the bonding surface of the bonding layer 110, thereby ensuring that there is no surface area of the device body 210 of the wearable device 200 where the adhesive directly contacts the area where the isolation layer 120 is located, thereby not only protecting the appearance of the wearable device 200 intactly, but also ensuring that the user can easily separate the fixing patch from the wearable device 200 during use, so as to more conveniently replace the fixing patch, which is more conducive to the reuse of multiplexed wearable devices (such as multiplexed transmitter-type wearable devices).
[0040] Please continue to refer to Figure 1 , Figure 2 and Figure 6 ,in, Figure 6 This is a schematic diagram of the wearing effect of the fixing patch provided by one embodiment of the utility model. Figure 1 , Figure 2 and Figure 6As shown, in some exemplary embodiments, the isolation layer 120 covers the middle area of the adhesive layer 110. Therefore, by covering the middle area of the adhesive layer 110 with the isolation layer 120, it can not only effectively ensure that there is no adhesive in the area where the isolation layer 120 is located to directly contact the surface area of the device body 210 of the wearable device 200, so as to protect the appearance of the wearable device 200 intactly, but also can achieve precise alignment of the wearable device 200 during use, so as to effectively ensure that the surface area of the device body 210 of the wearable device 200 will only contact the isolation layer 120, and will not contact the adhesive surface of the adhesive layer 110.
[0041] Please continue to refer to Figure 6 ,like Figure 6 As shown, in some exemplary embodiments, the area of the lower surface of the isolation layer 120 is greater than or equal to the area of the upper surface of the device body 210 of the medical wearable device. Therefore, this configuration can ensure that the isolation layer 120 can completely cover the upper surface of the device body 210 of the medical wearable device, thereby effectively ensuring that the surface area of the device body 210 of the wearable device 200 will only contact the isolation layer 120, and will not contact the adhesive surface of the adhesive layer 110, thereby effectively ensuring that the adhesive will not directly contact the surface area of the device body 210 of the wearable device 200, thereby better protecting the appearance of the wearable device 200.
[0042] In some exemplary embodiments, the isolation layer 120 includes an electrostatic diaphragm. Since the electrostatic diaphragm has good antistatic properties, by using the electrostatic diaphragm as the isolation layer 120 to separate the device body 210 of the wearable device 200 from the adhesive layer 110, the isolation layer 120 can be effectively prevented from affecting the use of the wearable device 200. Specifically, the material of the electrostatic diaphragm can be a soft and antistatic material such as non-woven fabric and silica gel.
[0043] In some exemplary embodiments, the adhesive layer 110 includes a flexible waterproof substrate (not shown in the figure) and an adhesive (not shown in the figure) disposed on the lower surface of the flexible waterproof substrate, and the adhesive is distributed on the lower surface of the flexible waterproof substrate to form the adhesive surface. Thus, by setting the adhesive layer 110 to include a flexible waterproof substrate and an adhesive disposed on the lower surface of the flexible waterproof substrate, it can be ensured that the adhesive layer 110 has certain waterproofness and flexibility, thereby improving the user experience.
[0044] Furthermore, the flexible waterproof substrate is a plastic film, and the adhesive is distributed in a dot-like manner on the lower surface of the plastic film. Therefore, the fixing patch provided by the utility model can ensure that the adhesive layer 110 has a certain waterproof property and good air permeability by setting the adhesive layer 110 to include a plastic film and an adhesive distributed in a dot-like manner on the lower surface of the plastic film, thereby further improving the user experience. At the same time, it can also make the adhesive layer 110 easier to separate from the wearable device 200 and the user's skin surface, so that when the user removes the adhesive layer 110, it will not affect the normal use of the wearable device 200, and thus it is convenient for the user to use and replace the fixing patch in special occasions. In addition, by using a plastic film to carry the adhesive, it can also achieve an invisible effect and better aesthetics.
[0045] In some exemplary embodiments, the flexible waterproof substrate is a PU film (polyurethane film). Since the PU film (polyurethane film) has good elasticity, it still has excellent waterproofness and excellent moisture permeability even when the thickness is extremely thin. Therefore, by using the PU film (polyurethane film) to carry the adhesive, not only the waterproofness of the adhesive layer 110 can be improved, but also the moisture permeability of the adhesive layer 110 can be improved, thereby effectively improving the comfort of the user when wearing the fixing patch provided by the utility model. In addition, since the PU film (polyurethane film) also has good transparency, it can also ensure that the fixing patch provided by the utility model has a better invisible effect.
[0046] Furthermore, the adhesive may be any one of medical polyacrylate adhesive, medical silicone adhesive, and medical polyurethane adhesive.
[0047] Furthermore, the adhesive is a skin-friendly glue. Thus, by using the skin-friendly glue as the adhesive of the adhesive layer 110, the comfort of the user when wearing the fixing patch provided by the utility model can be further improved.
[0048] Please continue to refer to Figure 1 , Figure 3 and Figure 4 ,like Figure 1 , Figure 3 and Figure 4As shown, in some exemplary embodiments, the fixing patch further includes a reinforcing layer 130, and the reinforcing layer 130 is at least attached to the outer edge of the upper surface of the adhesive layer 110, and the reinforcing layer 130 can be removed under the action of an external force. Therefore, the fixing patch provided by the utility model can not only ensure that when the user covers the fixing patch on the wearable device 200 with one hand, the fixing patch can be adhered to the surrounding side of the wearable device 200, but also ensure that the adhesive layer 110 is not easily deformed during the user's installation of the fixing patch, so that the adhesive layer 110 can be more smoothly attached to the user's skin surface, thereby further ensuring the fixing effect of the fixing patch. Specifically, the reinforcing layer 130 can be a reinforcing film or reinforcing paper that can provide the fixing patch with a certain degree of anti-deformation ability.
[0049] Please continue to refer to Figure 1 and Figure 4 ,like Figure 1 and Figure 4 As shown, in some exemplary embodiments, the reinforcing layer 130 exposes at least the middle area of the upper surface of the adhesive layer 110. Therefore, by setting the reinforcing layer 130 to expose at least the middle area of the upper surface of the adhesive layer 110, when the user covers the fixing patch on the wearable device 200 with one hand, the fixing patch can fit snugly on the peripheral side of the wearable device 200. In addition, by designing the reinforcing layer 130 to not completely cover the adhesive layer 110, it is helpful to save the material of the reinforcing layer 130, and at the same time, it can also reduce the contact area between the reinforcing layer 130 and the adhesive layer 110, so that it is more convenient for the user to remove the reinforcing layer 130 from the adhesive layer 110 with one hand, which is more convenient and labor-saving.
[0050] Please continue to refer to Figure 1 and Figure 4 ,like Figure 1 and Figure 4 As shown, in some exemplary embodiments, the reinforcing layer 130 has at least one slit 131, and at least one end of the slit 131 extends to the outer edge of the reinforcing layer 130. Therefore, by providing the slit 131 on the reinforcing layer 130, it is convenient for the user to easily remove the reinforcing layer 130 from the upper surface of the adhesive layer 110 through the slit 131 after the user sticks the adhesive layer 110 to the user's skin surface.
[0051] Preferably, the reinforcing layer 130 has a slit 131, one end of the slit 131 extends to the outer edge of the reinforcing layer 130, and the other end of the slit 131 extends to the inner edge of the reinforcing layer 130. Therefore, by providing a slit 131 on the reinforcing layer 130, one end of which extends to the outer edge of the reinforcing layer 130 and the other end of which extends to the inner edge of the reinforcing layer 130, the user can remove the reinforcing layer 130 as a whole from the upper surface of the adhesive layer 110 with only one operation.
[0052] Please continue to refer to Figures 2 to 4 ,like Figures 2 to 4 As shown, in some exemplary embodiments, the fixing patch also includes a protective layer 140 stacked below the isolation layer 120, the protective layer 140 covers the adhesive surface and the isolation layer 120, and the protective layer 140 can be removed under the action of an external force to expose the adhesive surface and the isolation layer 120. Therefore, by providing a protective layer 140 for covering the adhesive surface of the adhesive layer 110 and the isolation layer 120 on the lower surface of the isolation layer 120, the adhesive layer 110 and the isolation layer 120 can be protected, and the adhesive surface of the adhesive layer 110 can be effectively prevented from being exposed before use, so that the bonding effect of the adhesive layer 110 can be ensured, so as to further ensure the reliability of wearing the wearable device 200 that is reinforced and fixed by the fixing patch provided by the utility model. It should be noted that, as can be understood by those skilled in the art, the protective layer 140 can be a release paper or a release film.
[0053] Please continue to refer to Figures 2 to 4 ,like Figures 2 to 4 As shown, in some exemplary embodiments, the protective layer 140 includes a first sub-protective layer 141 and a second sub-protective layer 142, the first sub-protective layer 141 covers the adhesive surface and a side area of the isolation layer 120, and the second sub-protective layer 142 covers the adhesive surface and a side area of the isolation layer 120. Therefore, by setting the protective layer 140 as a split structure including the first sub-protective layer 141 and the second sub-protective layer 142, it is easier for the user to complete the enhanced fixing operation of the fixing patch on the wearable device 200 with one hand. In addition, compared with the traditional multi-piece protective structure, since the fixing patch provided by the utility model has only two protective structures, the first sub-protective layer 141 and the second sub-protective layer 142, the user operation is simpler and more convenient, which is more conducive to the user's single-handed wear and use.
[0054] Please continue to refer to Figure 2 and Figure 3 ,like Figure 2 and Figure 3As shown, in some exemplary embodiments, a side area of the first sub-protective layer 141 close to the second sub-protective layer 142 overlaps with a side area of the second sub-protective layer 142 close to the first sub-protective layer 141 to form an interlaced area 143. Thus, by partially interlacing the first sub-protective layer 141 and the second sub-protective layer 142 to form an interlaced area 143, a tearing position can be provided for the user through the interlaced area 143, so as to make it easier for the user to perform one-handed operation. It should be noted that, as can be understood by those skilled in the art, one side of one of the first sub-protective layer 141 and the second sub-protective layer 142 close to the other is stacked below the other to partially overlap, thereby forming an interlaced area 143. It should also be noted that, as can be understood by those skilled in the art, in the specific use process, the one located at the bottom of the first sub-protective layer 141 and the second sub-protective layer 142 is first removed, and after the pre-fixation is completed, the other is removed.
[0055] Please continue to refer to Figure 1 and Figure 2 ,like Figure 1 and Figure 2 As shown, in some exemplary embodiments, the outer shape of the adhesive layer 110 is elliptical or approximately elliptical. Thus, by setting the adhesive layer 110 to be elliptical or approximately elliptical, it can be more ergonomic, so that the adhesive layer 110 can be better bonded to the surface of human skin. It should be noted that, as can be understood by those skilled in the art, the outer shape of the adhesive layer 110 can also be other shapes, and the present invention is not limited to this.
[0056] The specific use process of the fixing patch provided by the utility model is described below. Figures 7 to 11 ,in, Figure 7 A schematic diagram of the structure when one of the sub-protective layers 140 in the fixing sticker provided in one embodiment of the utility model is removed; Figure 8 This is a schematic diagram of the structure of the fixing patch provided by one embodiment of the utility model when it is attached to the skin surface of the user for pre-fixation; Fig. 9 This is a schematic diagram of the structure when another sub-protective layer 140 in the fixing sticker provided in one embodiment of the utility model is removed; Fig.10 This is a schematic diagram of the structure of the fixing patch provided by one embodiment of the utility model after being completely bonded and fixed to the skin surface of the user; Fig.11 This is a schematic diagram of the structure of the fixing patch provided by one embodiment of the utility model when the reinforcing layer 130 is removed. Figures 7 to 11As shown, the specific installation process of the fixing sticker provided by the utility model includes the following steps: Step 1, remove the lower one of the first sub-protective layer 141 and the second sub-protective layer 142 from the lower surface of the adhesive layer 110 and the isolation layer 120 ( Figure 7 Since the first sub-protective layer 141 is located at the bottom, the first sub-protective layer 141 is removed first); Step 2, align the isolation layer 120 of the fixing patch after removing one of the sub-protective layers 140 (for example, the first sub-protective layer 141) with the wearable device 200, and cover the fixing patch after removing the first sub-protective layer 141 on the top of the wearable device 200 and bond the exposed adhesive surface of one side of the adhesive layer 110 to the skin surface located around the wearable device 200 and the upper surface of the adhesive patch 220 at the bottom of the wearable device 200 for pre-bonding; Step 3, align the first sub-protective layer 140 with the wearable device 200, and cover the wearable device 200 with the fixing patch after removing the first sub-protective layer 141. 141 and the other of the second sub-protective layer 142 (for example, the second sub-protective layer 142) are removed from the lower surfaces of the adhesive layer 110 and the isolation layer 120; Step 4, the exposed other side adhesive surface of the adhesive layer 110 is bonded to the skin surface located around the wearing device 200 and the upper surface of the adhesive sticker 220 at the bottom of the wearing device 200, so that the fixing sticker completely covers the wearing device 200 and is completely bonded to the surrounding skin; Step 5, the reinforcing layer 130 is removed from the upper surface of the adhesive layer 110, and the adhesive layer 110 is smoothed to complete the installation of the fixing sticker.
[0057] In summary, compared with the prior art, the fixing patch provided by the utility model has the following beneficial effects:
[0058] (1) Since the adhesive layer 110 in the fixing patch provided by the utility model can cover the entire area of the wearable device 200, it can not only strengthen the edge of the adhesive patch 220 that fixes the wearable device 200, but also cover the wearable device 200 itself (i.e., the device body 210). At the same time, the overall adhesion of the fixing patch is good, the bonding area is large enough, and sufficient bonding force can be provided, thereby greatly improving the wearing reliability of the wearable device 200.
[0059] (2) The fixing patch provided by the present invention can separate the device body 210 of the wearable device 200 from the adhesive surface of the adhesive layer 110 when strengthening the fixation of the wearable device 200 by setting an isolation layer 120, thereby ensuring that there is no surface area of the device body 210 of the wearable device 200 where the adhesive directly contacts the area where the isolation layer 120 is located. This can not only protect the appearance of the wearable device 200, but also ensure that the user can easily separate the fixing patch from the wearable device 200 during use, so as to more conveniently replace the fixing patch, which is more conducive to the reuse of multiplexed wearable devices (such as multiplexed transmitter-type wearable devices).
[0060] (3) The fixing patch provided by the utility model can not only ensure that when the user covers the fixing patch on the wearable device 200 with one hand, the fixing patch can be attached to the surrounding side of the wearable device 200 by providing a reinforcing layer 130 attached to at least the outer edge of the upper surface of the adhesive layer 110, but also ensure that the adhesive layer 110 is not easily deformed during the user's installation of the fixing patch, so that the adhesive layer 110 can be more smoothly attached to the user's skin surface, thereby further ensuring the fixing effect of the fixing patch. In addition, by providing a slit 131 on the reinforcing layer 130, the user can easily remove the reinforcing layer 130 from the upper surface of the adhesive layer 110 through the slit 131 after the user has attached the adhesive layer 110 to the user's skin surface.
[0061] (4) The fixing patch provided by the utility model can ensure that the adhesive layer 110 has a certain waterproof property and good air permeability by setting the adhesive layer 110 to include a plastic film and an adhesive distributed in a dot-like manner on the lower surface of the plastic film, thereby improving the user experience and making it easier to separate the adhesive layer 110 from the wearable device 200 and the user's skin surface, so that the user can remove the adhesive layer 110 without affecting the normal use of the wearable device 200, thereby making it convenient for the user to use and replace the fixing patch in special occasions. In addition, by using a plastic film to carry the adhesive, it can also achieve an invisible effect and better aesthetics.
[0062] (5) The fixing patch provided by the utility model can protect the adhesive layer 110 and the isolation layer 120 by providing a protective layer 140 on the lower surface of the isolation layer 120 for covering the adhesive surface of the adhesive layer 110 and the isolation layer 120, and effectively prevent the adhesive surface of the adhesive layer 110 from being exposed before use, thereby ensuring the bonding effect of the adhesive layer 110. In addition, by providing the protective layer 140 as a split structure including a first sub-protective layer 141 and a second sub-protective layer 142, it can be more convenient for the user to complete the enhanced fixing operation of the fixing patch on the wearable device 200 with one hand. Furthermore, by partially staggering the first sub-protective layer 141 and the second sub-protective layer 142 to form a staggered area 143, the staggered area 143 can provide the user with a tearing position, thereby making it more convenient for the user to perform one-handed operation.
