Description

Technical Field

[0001] This invention belongs to the field of conductive physiotherapy patch technology, specifically a multi-textured conductive physiotherapy patch and its preparation process. Background Technology

[0002] Conductive therapy patches are therapeutic devices that use electrical stimulation to relieve pain and promote tissue repair. They typically consist of a base layer, a conductive layer, and an adhesive layer. To increase the contact area with the skin, the conductive layer is usually designed with a grid or stripe pattern to create multiple textures.

[0003] For example, the invention application with publication number CN116899112A discloses a magnetic light-transmitting pressure physiotherapy patch and physiotherapy device in the field of physiotherapy equipment technology. The patch includes a body, a conductive adhesive is glued to one side of the patch, and a through hole is opened inside the patch and the conductive adhesive. A pressure column is sleeved inside the through hole, a guide column is slidably connected inside the through hole, and a magnetic sheet is fixedly connected to the top of the guide column.

[0004] Based on the above cases and actual situations, we have found the following problems: When using physiotherapy patches for physiotherapy, not only are conductive physiotherapy applied to acupoints, but there are also cases where conductive physiotherapy is applied directly to the patient's painful areas. However, acupoints are usually small in area, while the area of ​​pain for patients is large. Existing conductive physiotherapy is difficult to adapt to the changes in the physiotherapy area. When the conductive area is large, the contact area between the two is small and the physiotherapy effect is poor when applying physiotherapy to acupoints. When the conductive area is small, the physiotherapy effect is poor when applying physiotherapy to patients' pain. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-textured conductive physiotherapy patch and its manufacturing process. By setting an adjustment component, during physiotherapy, rotating the knob pushes the conductive protrusions on both sides to spread to both sides through the transmission structure, thereby increasing the distribution range of the conductive protrusions. At the same time, in conjunction with the change of airbag pressure, the pressure between the conductive protrusions and the skin is adaptively adjusted, so as to solve the above-mentioned problems of the prior art.

[0006] To achieve the above objectives, the present invention provides a multi-textured conductive physiotherapy patch, including a patch assembly. The patch assembly consists of an upper base layer and a lower pad layer. An adjustment component is provided on the base layer. The adjustment component includes a plurality of regularly distributed conductive protrusions and a knob for adjusting the spacing of the conductive protrusions through a transmission structure. A plurality of airbags are provided above the conductive protrusions and are regularly distributed perpendicular to them. The conductive protrusions are disposed between the base layer and the pad layer. The left and right ends of the airbags are respectively fixedly bonded to the top surface of the left and right outermost conductive protrusions.

[0007] In this setting, rotating the knob causes the conductive protrusions to slide, thereby changing the distribution range of the conductive protrusions and adjusting them according to the required treatment area to improve the treatment effect. At the same time, the airbag changes the pressure on the conductive protrusions as they slide, improving the comfort of the treatment.

[0008] The transmission structure includes a rotating plate whose top surface is coaxially fixed with the bottom end of the knob and two transmission rods symmetrically arranged on the left and right sides. A sliding plate is hinged to the outer end of the transmission rod. A plurality of connecting rods corresponding to a plurality of conductive protrusions are hinged from the inside to the outside on the bottom surface of the sliding plate. The bottom end of the connecting rod is hinged to the corresponding conductive protrusion. A fixed rotating shaft is provided on the connecting rod in the front and rear transverse directions.

[0009] In this setup, the rotating knob drives the sliding plate to slide left and right via the rotating plate and transmission rod, which in turn drives the connecting rod to rotate around the fixed rotating shaft, thereby causing the conductive protrusions to slide left and right to change the spacing.

[0010] The base layer is provided with a movable groove, and the movable groove is provided with two breathable plates. The two breathable plates are symmetrically arranged on the left and right and staggered vertically. The base layer is provided with a number of regularly distributed breathable holes, and the breathable plates are provided with air guide holes corresponding to the size of the breathable holes.

[0011] In this setup, the breathable plate changes its position as the conductive protrusions slide, adapting to different treatment areas and improving the therapeutic effect while ensuring breathability.

[0012] In the technical solution of the present invention, the base layer is made of elastic silicone, the pad is made of non-woven fabric and coated with silicone pressure-sensitive adhesive on the bottom surface, a layer of release paper is pasted on the bottom surface of the pad, a fixing shell is glued and fixed in the middle of the top surface of the base layer, an opening is provided below the pad for the conductive protrusion to contact the user's skin, and a connecting part with Velcro is provided on the rear side of the top surface and the front side of the bottom surface of the base layer.

[0013] In this setup, silicone pressure-sensitive adhesive makes the bottom surface of the pad sticky, allowing it to adhere to the skin and improve fixation. The pad has openings that allow the conductive strips to contact the skin. Through the Velcro on the connecting part, the kinesiology tape can be better fixed to the arm during arm physiotherapy.

[0014] In the technical solution of the present invention, the conductive protrusion is arranged along the length direction of the base layer, and the bottom surface of the base layer is bonded with left and right transverse sliding rods at the front and rear ends. The sliding rods pass through the corresponding ends of the conductive protrusion and are slidably connected. The left and right surfaces and the top surface of the conductive protrusion are coated with insulating paint, and the sliding rods are protected from being coated with insulating paint.

[0015] In this design, a smooth sliding rod is used to avoid excessive resistance, which could cause the conductive protrusion to deform laterally and affect its use. The application of insulating coating ensures that the conductive protrusion conducts electricity only on the bottom surface.

[0016] In the technical solution of the present invention, the connecting rod is composed of a fixed part and a sliding part inserted together. The sliding plate is fixed with a plurality of movable rotating shafts corresponding one-to-one with the plurality of connecting rods. The fixed part of the connecting rod near the middle is hinged to the corresponding movable rotating shaft. The sliding part of the connecting rod near the middle is hinged to the top surface of the corresponding conductive protrusion. The fixed part of the connecting rod near the outer side is hinged to the top surface of the corresponding conductive protrusion. The sliding part of the connecting rod near the outer side is hinged to the corresponding movable rotating shaft.

[0017] In this configuration, when the sliding plate slides inward, the movable pivot drives the top of the connecting rod to move closer to the center and causes the connecting rod to rotate around the fixed pivot. By setting up the fixed part and the sliding part, the connecting rod can be stretched and extended.

[0018] In the technical solution of the present invention, the front and rear ends of the fixed rotating shaft are respectively fixed between the front and rear inner sidewalls of the fixed shell. The height of the fixed rotating shaft on the inner side is lower than the height of the fixed rotating shaft on the outer side. The fixed rotating shaft passes through the corresponding fixed part and the two are hinged. A left and right horizontal baffle is fixed inside the fixed shell near the bottom surface. The baffle is located between the middle airbag and the bottom fixed rotating shaft.

[0019] In this setup, by setting different heights for the fixed pivot, the outermost connecting rod moves outward a greater distance, ensuring that the distance between adjacent conductive protrusions increases, thereby improving the uniformity of the conductive protrusion distribution and enhancing the therapeutic effect. By setting a baffle to prevent the central airbag from expanding upward, the corresponding conductive protrusion in the center cannot be subjected to downward pressure, thus preventing the conductive protrusion from adhering to the skin. The airbags on both sides, due to the base layer on top, can also ensure that the airbags exert downward pressure on the conductive protrusions.

[0020] In the technical solution of the present invention, the transmission rod is hinged to the bottom surface of the rotating plate, and a fixing plate is symmetrically fixed on the top surface of the fixed shell. The fixing plate is arranged laterally on the left and right sides. A limit block is fixed to the inner end of the top surface of the sliding plate, and the limit block is slidably connected to the fixing plate.

[0021] In this setup, a fixed plate is used to restrict the sliding plate, ensuring that the sliding plate can only be pulled left and right by the transmission rod under the constraint of the limit block.

[0022] In the technical solution of the present invention, a knob seat is fixed in the middle of the fixed shell, and a bolt structure is symmetrically provided on the knob. The bolt structure includes a pressing plate and a bolt fixedly connected to the lower inner end of the pressing plate. The knob is provided with a pressure plate groove corresponding to the position of the pressing plate. A locking block is fixed on the front and rear side walls of the pressing plate. A limiting rod is provided in the front and rear side walls of the pressure plate groove. The limiting rod passes through the corresponding locking block and the two are slidably connected. A spring is sleeved between the inner end of the limiting rod and the inner side wall of the locking block.

[0023] In this setting, when the pressure plate is pressed inward, it can slide within the pressure plate groove. When released, the pressure plate is ejected outward by the spring's restoring force.

[0024] In the technical solution of the present invention, the inner wall of the knob seat is provided with a plurality of plug holes, the plug holes are distributed counterclockwise, and the plug holes correspond to the size of the plug.

[0025] In this setup, when the knob needs to be rotated, the user presses the pressure plate with their hand, which moves the plug inward and away from the original plug hole. Then, the pressure plate is released and the knob is rotated counterclockwise, allowing the plug to enter the adjacent plug in the counterclockwise direction and be re-secured. This avoids the inability to fix the spacing after adjusting the spacing of the conductive protrusions.

[0026] In the technical solution of the present invention, the front and rear side walls of the ventilator are fixed with flanges at their outer ends, the front and rear side walls of the movable groove are provided with flange grooves for the flanges to slide, the middle part of the ventilator is fixed to the outer end of the sliding plate, the air guide holes correspond one-to-one with the air vents and the distance between adjacent air guide holes on the left and right is greater than the diameter of the air vents.

[0027] In this setup, the two ventilation panels are positioned such that when they are close together, they can cover the ventilation holes on both sides, and when the two ventilation panels are far apart, the ventilation hole in the middle still has an air opening.

[0028] On the other hand, the present invention also provides a preparation process for a multi-textured conductive therapeutic skin patch, which is used to prepare the above-mentioned multi-textured conductive therapeutic skin patch, including the following steps:

[0029] S1. Soak the silicone base layer in a silane coupling agent solution for 10 minutes, dry it and set it aside. Sew and cut a suitable non-woven fabric, disinfect it and make it into a padding layer.

[0030] S2. Prepare stainless steel strips of appropriate length. Mix conductive silver paste and elastic resin in a ratio of 7:3 and add 1-2% photoinitiator. After mixing, apply the mixture to the bottom of the stainless steel strip. Then mix epoxy resin and curing agent in a ratio of 9:1 to form an insulating coating and apply it to the remaining surface of the stainless steel strip. After drying the surface of the stainless steel strip, a conductive raised strip is formed.

[0031] S3. The fixing shell is chemically bonded to the base layer, and the adjustment components are assembled. After assembly, the pad is bonded to the corresponding position on the bottom of the base layer, and the release paper is attached to the surface of the pad to complete the preparation.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] 1. In this invention, by setting an adjustment component, when the required treatment area is small, the conductive protrusions are concentratedly distributed, increasing the contact area between the conductive protrusions and the acupoints, enabling the conductive protrusions to effectively treat the acupoints. At the same time, the expanding airbag applies downward pressure to the conductive protrusions, making them adhere tightly to the skin, further enhancing the treatment effect. When the required treatment area is large, rotating the knob drives the sliding plate to slide towards the center via the transmission rod, which in turn drives the bottom end of the connecting rod to slide outward, thereby causing the conductive protrusions on both sides to slide outward and spread, thus changing the distribution range of the conductive protrusions to adapt to different treatment areas and improve the treatment effect.

[0034] 2. In this invention, when the conductive protrusion slides outward and diffuses, the breathable plate slides outward synchronously with the conductive protrusion, thereby changing the corresponding position of the air guide hole and the breathable hole, so that the air guide hole and the breathable hole on the left and right sides overlap to allow air to pass through. The breathable hole in the middle is blocked by the breathable plate, reducing the breathable area. This allows the main breathable position to change according to the usage. For small-area physiotherapy, the breathable position is only in the middle to prevent dust and other particles from entering and affecting the conductivity of the conductive protrusion. For large-area physiotherapy, the breathable position is evenly distributed on the base layer to ensure the breathability effect. Attached Figure Description

[0051] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0052] Unless otherwise expressly stated, throughout this specification, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0053] Reference Figures 1-13 As shown, this embodiment provides a technical solution:

[0054] A multi-textured conductive physiotherapy patch includes a patch assembly 100, which consists of an upper base layer 101 and a lower pad layer 104. An adjustment component 200 is provided on the base layer 101. The adjustment component 200 includes several regularly distributed conductive protrusions 202 and a knob 203 for adjusting the spacing of the conductive protrusions 202 via a transmission structure 210. Several airbags 205 are regularly distributed perpendicularly above the conductive protrusions 202. The conductive protrusions 202 are positioned between the base layer 101 and the pad layer 104. The left and right ends of the airbags 205 are fixedly bonded to the top surfaces of the outermost conductive protrusions 202. When the required physiotherapy area is small, such as when only acupoints are treated, the conductive protrusions 202 are adjusted... Figure 2 The conductive protrusions 202 are concentrated and distributed to increase the contact area between the conductive protrusions 202 and the acupoints, so that the conductive protrusions 202 can effectively treat the acupoints.

[0055] When the required treatment area is large, rotating the knob 203 pushes the conductive protrusions 202 on both sides to spread outwards through the transmission structure 210, thereby increasing the distribution range of the conductive protrusions 202 and improving the treatment effect. When the conductive protrusions 202 are gathered, the contact surface between the conductive protrusions 202 and the skin is concentrated, which may cause the conductive protrusions 202 and the skin to not be completely adhered. By setting the airbag 205, when the conductive protrusions 202 are gathered, the two ends of the airbag 205 are squeezed towards the middle, so that the airbag 205 can exert a downward pressure on the conductive protrusions 202, helping the conductive protrusions 202 to better adhere to the skin. When the conductive protrusions 202 are dispersed, the two ends of the airbag 205 are stretched to both ends, so that the pressure of the airbag 205 on the conductive protrusions 202 is reduced, avoiding excessive pressure on the skin from a single conductive protrusion 202, which would affect the comfort of the treatment.

[0056] The transmission structure 210 includes a rotating plate 211 whose top surface is coaxially fixed with the bottom of the knob 203 and two transmission rods 216 symmetrically arranged on the left and right sides. A sliding plate 212 is hinged to the outer end of the transmission rod 216. A number of connecting rods 213 corresponding to a number of conductive protrusions 202 are hinged from the inside to the outside on the bottom surface of the sliding plate 212. The bottom end of the connecting rod 213 is hinged to the corresponding conductive protrusion 202. A fixed rotating shaft 218 is provided on the connecting rod 213 in a front-back transverse direction. By rotating the knob 203 counterclockwise, the transmission rod 216 drives the sliding plate 212 to slide towards the center, thereby driving the bottom end of the connecting rod 213 to slide outward, and thus causing the conductive protrusions 202 on both sides to slide outward and spread.

[0057] The base layer 101 has a movable groove 105, and two breathable plates 106 are installed in the movable groove 105. The two breathable plates 106 are symmetrically arranged on the left and right and staggered vertically. The base layer 101 has a number of regularly distributed breathable holes 103. The breathable plates 106 have air guide holes 106a corresponding to the size of the breathable holes 103. When the conductive protrusion 202 slides outward and diffuses, the breathable plate 106 slides outward synchronously with the conductive protrusion 202, thereby changing the corresponding position of the air guide holes 106a and the breathable holes 103, so that the air guide holes 106a and the breathable holes 103 on the left and right sides overlap for ventilation. The breathable holes 103 in the middle are reduced in ventilation area by the obstruction of the breathable plate 106, so that the main ventilation position changes according to the usage. For small-area physiotherapy, the ventilation position is only in the middle to avoid dust and other objects from entering and affecting the conductivity of the conductive protrusion 202. For large-area physiotherapy, the ventilation position is evenly distributed in the base layer 101 to ensure the ventilation effect.

[0058] Please see Figure 1-2 As shown, the base layer 101 is made of elastic silicone, and the pad layer 104 is made of non-woven fabric with a silicone pressure-sensitive adhesive coating on the bottom surface, making the bottom surface of the pad layer 104 sticky and able to adhere to the skin. A layer of release paper is pasted on the bottom surface of the pad layer 104 to prevent the pad layer 104 from sticking when not in use. A fixing shell 201 is glued and fixed to the middle of the top surface of the base layer 101. An opening is provided at the bottom of the pad layer 104 for the conductive protrusions 202 to contact the user's skin. The opening is larger than or equal to the maximum distribution range of the conductive protrusions 202 to avoid affecting the contact between the conductive protrusions 202 and the skin. The rear side of the top surface and the front side of the bottom surface of the base layer 101 are provided with connecting parts 102 with Velcro. Through the Velcro on the connecting parts 102, the kinesiology tape can be better fixed on the arm during arm physiotherapy.

[0059] Please see Figures 3-5 As shown, the conductive protrusion 202 is set along the length of the base layer 101. The conductive protrusion 202 is a stainless steel strip that can be bent along its length. The bottom surface of the base layer 101 has left and right horizontal sliding rods 207 bonded to the front and rear ends. The sliding rods 207 pass through the corresponding ends of the conductive protrusion 202 and are slidably connected. The surface of the sliding rods 207 is smooth to avoid excessive resistance, which would cause the conductive protrusion 202 to deform directly to the left and right when sliding, affecting its use. The left, right and top surfaces of the conductive protrusion 202 are coated with insulating paint. The sliding rods 207 are not coated with insulating paint to ensure that the conductive protrusion 202 is conductive only on the bottom surface. A conductive interface is provided on the rear side of the fixing shell 201. The conductive protrusion 202 is electrically connected to the conductive interface through a wire. The specific connection and wiring method is the existing technology of conductive skin tape and will not be described in detail here.

[0060] Please see Figures 6-8As shown, the connecting rod 213 is composed of a fixed part 213a and a sliding part 213b connected together. The sliding plate 212 is fixed with a number of movable shafts 214 corresponding to the connecting rods 213. The fixed part 213a of the middle connecting rod 213 is hinged to the corresponding movable shaft 214, and the sliding part 213b of the middle connecting rod 213 is hinged to the top surface of the corresponding conductive protrusion 202. The fixed part 213a of the outer connecting rod 213 is hinged to the top surface of the corresponding conductive protrusion 202, and the sliding part 213b of the outer connecting rod 213 is hinged to the corresponding movable shaft 214. When the sliding plate 212 slides inward, the movable shaft 214 drives the top of the connecting rod 213 to move closer to the center and makes the connecting rod 213 rotate around the fixed shaft 218. By setting the fixed part 213a and the sliding part 213b, the connecting rod 213 can be stretched and extended.

[0061] Furthermore, the front and rear ends of the fixed pivot 218 are respectively fixed between the front and rear inner walls of the fixed shell 201. The height of the inner fixed pivot 218 is lower than that of the outer fixed pivot 218, so that the bottom end of the outermost connecting rod 213 moves outward a greater distance, ensuring that the distance between adjacent conductive protrusions 202 is increased, thereby improving the uniformity of the distribution of conductive protrusions 202 and improving the physiotherapy effect. The fixed pivot 218 passes through the corresponding fixed part 213a and the two are hinged. A left and right horizontal baffle 206 is fixed inside the fixed shell 201 near the bottom surface. The baffle 206 is located between the middle airbag 205 and the bottom fixed pivot 218. By setting the baffle 206, the middle airbag 205 is prevented from expanding upward, so that the middle part of the corresponding conductive protrusion 202 cannot be subjected to downward pressure, thereby causing the conductive protrusion 202 to be unable to adhere to the skin. The airbags 205 on both sides, due to the base layer 101 on the top, can also ensure that the airbags 205 exert downward pressure on the conductive protrusions 202.

[0062] Specifically, the transmission rod 216 is hinged to the bottom surface of the rotating plate 211. The top surface of the fixed shell 201 is symmetrically fixed with fixed plates 215 on the left and right sides. The fixed plates 215 are arranged horizontally on the left and right sides. The top surface of the sliding plate 212 is fixed with a limit block 217 near the inner end. The limit block 217 is slidably connected to the fixed plate 215. By setting the fixed plate 215 to restrict the sliding plate 212, the sliding plate 212 can only be pulled left and right by the transmission rod 216 under the restriction of the limit block 217.

[0063] Please see Figures 9-11As shown, a knob seat 204 is fixed in the middle of the fixed shell 201. A plug structure 220 is symmetrically provided on the left and right sides of the knob 203. The plug structure 220 includes a pressing plate 221 and a plug 226 fixedly connected to the lower part of the inner end of the pressing plate 221. The knob 203 is provided with a pressure plate groove 222 corresponding to the position of the pressing plate 221. A locking block 223 is fixed on the front and rear side walls of the pressing plate 221. A limiting rod 224 is provided in the front and rear side walls of the pressure plate groove 222. The limiting rod 224 passes through the corresponding locking block 223 and the two are slidably connected. A spring 225 is sleeved between the inner end of the limiting rod 224 and the inner side wall of the locking block 223. When the pressing plate 221 is pressed inward, it can slide in the pressure plate groove 222. When released, the pressing plate 221 is ejected outward under the restoring force of the spring 225.

[0064] The inner wall of the knob seat 204 is provided with several plug holes 204a, which are distributed counterclockwise. The plug holes 204a correspond to the size of the plugs 226. When the knob 203 needs to be rotated, the user presses the pressing plate 221 with his hand, which moves the plugs 226 inward and away from the original plug holes 204a. Then, the pressing plate 221 is released and the knob 203 is rotated counterclockwise so that the plugs 226 can be inserted into the adjacent plugs 226 in the counterclockwise direction and thus be fixed again. This avoids the inability to fix the spacing after adjusting the spacing of the conductive protrusions 202.

[0065] Please see Figures 12-13 The vent plate 106 has flanges fixed to the outer ends of its front and rear side walls. The movable groove 105 has flange grooves on its front and rear side walls for the flanges to slide. The flange grooves and flanges support the vent plate 106, preventing the upper and lower vent plates 106 from tilting together. The middle part of the vent plate 106 is fixed to the outer end of the sliding plate 212, so that the vent plate 106 can be adjusted synchronously with the conductive protrusion 202. The air guide hole 106a corresponds one-to-one with the air vent 103, and the distance between the left and right adjacent air guide holes 106a is greater than the diameter of the air vent 103. This ensures that when the two vent plates 106 are close to each other, they can block the air vents 103 on both sides. When the two vent plates 106 are far apart, the middle air vent 103 still has an air opening. In addition, the vent plate 106 is made of elastic silicone.

[0066] This invention also provides a manufacturing process for a multi-textured conductive physiotherapy patch, which includes the following steps:

[0067] S1. Soak the silicone base layer 101 in a silane coupling agent solution for 10 minutes, dry it and set it aside. Sew and cut a suitable non-woven fabric, and sterilize it to make the padding layer 104.

[0068] S2. Prepare stainless steel strips of appropriate length. Mix conductive silver paste and elastic resin in a ratio of 7:3 and add 1-2% photoinitiator. After the mixture is completed, apply it to the bottom of the stainless steel strip. Then mix epoxy resin and curing agent in a ratio of 9:1 to form an insulating coating and apply it to the remaining surface of the stainless steel strip. After drying the surface of the stainless steel strip, conductive raised strip 202 is formed.

[0069] S3. The fixing shell 201 is chemically bonded to the base layer 101, and the adjustment component 200 is assembled. After assembly, the pad 104 is bonded to the corresponding position on the bottom surface of the base layer 101, and the release paper is attached to the surface of the pad 104 to complete the preparation.
