Description

Technical Field

[0001] This invention relates to the field of medical electrode patch technology, specifically a fabric heating electrode patch. Background Technology

[0002] Electrode patches are an auxiliary device in medical electronic instruments. With the continuous development of medical technology, different types of electrode patches have appeared on the market. The "electrode patch for physiotherapy" disclosed in patent CN213192130U includes an electrode patch body, a connecting wire fixedly installed at the connection between two electrode patch bodies, a Velcro rivet surface fixed to the inside of the rear surface of the electrode patch body by adhesive, and a protective surface provided at the middle position of the lower surface of the electrode patch body. The electrode patch body is formed by pressing the various composite layers together through a pressing process.

[0003] Currently, the bonding tightness of the various composite layers of the electrode patch body on the market is poor. During the use of the electrode patch, the various composite layers of the electrode patch body often separate from each other, or there are large gaps between the composite layers, which affects the service life of the electrode patch. In addition, existing electrode patches are divided into categories such as heating electrode patches and ECG conductive electrode patches, and the functions of electrode patches are relatively simple. Summary of the Invention

[0004] The purpose of this invention is to provide a fabric heating electrode patch to solve the problems mentioned in the background art.

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

[0006] A fabric heating electrode patch, comprising:

[0007] The electrode patch body is composed of an upper fabric layer, a sponge layer, a lower fabric layer, a heating element, a hydrogel layer, and a conductive element that are pressed together in sequence. At least one side of the electrode patch body is provided with a reinforcing member.

[0008] The control box is pressed onto the center of the top surface of the electrode body by at least one set of strong magnetic conductive buttons. The control box consists of a bottom shell, a PCB board, a battery, buttons, and a front shell.

The heating sheet, the conductive sheet, the lower fabric layer, the sponge layer, and the upper fabric layer have perforated components at the top center for the male button to pass through vertically.

[0012] Preferably, the bottom of the female buckle is provided with an opening for receiving the male buckle, and the top of the female buckle is connected to a pair of insert rods via a coupling, with the insert rods extending vertically into the bottom shell.

[0013] Preferably, the fixing piece is pressed onto the top center of the conductive piece, and a through hole is formed in the center of the fixing piece.

[0020] This invention integrates heating and electrode functions, featuring a robust and stable overall structure and a long service life. With the cooperation of reinforcing components and a strong magnetic conductive button, the various layers of the electrode patch are doubly connected to firmly bond them together. This achieves a tight fit between the fabric layer, sponge layer, conductive sheet, heating sheet, and button, ensuring that the various layers remain in a balanced and stable state during use. This improves the overall structural strength and stability of the electrode patch, contributing to its long-term durability. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-7 This invention provides a technical solution: a fabric heating electrode patch, comprising an electrode patch body and a control box. The electrode patch body is composed of an upper fabric layer 9, a sponge layer 10, a lower fabric layer 11, a heating element 12, a hydrogel layer 15, and a conductive element 13, which are sequentially pressed together. At least one side of the electrode patch body is provided with reinforcing members. The control box is pressed onto the center of the top surface of the electrode patch body by at least one set of strong magnetic conductive buttons. The control box consists of a bottom shell 5, a PCB board 3, a battery 4, a button 2, and a front shell 1. The battery 4 is, but is not limited to, a zinc-mercury battery, a zinc-air battery, a solid electrolyte battery, or a lithium battery. The PCB board 3 is electrically connected to the battery 4, and the button 2 is mounted on the PCB board 3. The structural principles and connection methods of the battery 4, button 2, PCB board 3, bottom shell 5, and front shell 1 are well-known technologies in the market and will not be described in detail here. The bottom shell 5 and the front shell 1 are detachably connected together.

[0031] The aforementioned strong magnetic conductive button, in conjunction with the reinforcing member, bonds the upper fabric layer 9, the sponge layer 10, the lower fabric layer 11, the heating element 12, and the conductive element 13 together. The hydrogel in the hydrogel layer 15 is, but is not limited to, polyurethane hydrogel, PTMC-F127-PTMC thermosensitive hydrogel, and injection-type PNIPAM hydrogel. Other types, such as PLGA-PEG-PLGA hydrogel and K-type carrageenan / polyvinylpyrrolidone blend hydrogel, are also applicable to this embodiment. The structure and principle of the hydrogel are well-known technologies in the market, and therefore will not be described in detail here.

[0032] Specifically, the lower fabric layer 11 and the upper fabric layer 9 have the same structure and external dimensions. The fabric in the upper fabric layer 9 and the lower fabric layer 11 is made of, but is not limited to, non-woven fabric, cotton fabric, nylon fabric or polyester fabric. Other fabrics such as linen are also applicable to this embodiment.

[0033] Specifically, the length of the sponge layer 10 does not exceed the length of the upper fabric layer 9. The sponge layer 10 is made of synthetic sponge, but not limited to, low-density polyether, polyvinyl alcohol or polyester. Other materials such as molded sponge and rubber sponge are also applicable to this embodiment.

[0034] Specifically, the length of the heating element 12 does not exceed the length of the lower fabric layer 11. The heating element 12 is, but is not limited to, a graphene heating element or a ceramic heating element. The length of the heating element 12 is one-third of the length of the lower fabric layer 11, that is, the heating element 12 is located in the middle of the lower fabric layer 11.

[0035] Specifically, the conductive sheet 13 is made of conductive silicone or nickel-plated copper, and the length of the conductive sheet 13 does not exceed the length of the lower fabric layer 11.

[0036] In this embodiment, the reinforcement includes a protrusion 131 connected to the conductive sheet 13 and a reinforcing ring 8 located on the upper fabric layer 9 and fitted onto the protrusion 131. The protrusion 131 inserts into the lower fabric layer 11 and the sponge layer 10 sequentially from bottom to top and extends out of the upper fabric layer 9. The top sides of the lower fabric layer 11, the sponge layer 10, and the upper fabric layer 9 are provided with insertion hole assemblies for the protrusion 131 to pass through vertically. The insertion hole assembly includes a first insertion hole 901, a second insertion hole 101, and a third insertion hole 901. The first socket 901 is located on one side of the upper fabric layer 9, the second socket 101 is located on one side of the sponge layer 10, and the third socket 111 is located on one side of the lower fabric layer 11. The socket structure and external dimensions of the first socket 901, the second socket 101 and the third socket 111 are the same, that is, the socket shape of the first socket 901, the second socket 101 and the third socket 111 are all elliptical. The overall shape of the protrusion 131 mentioned is elliptical.

[0037] It should be noted that the dimensions of sockets 1 (901), 2 (101), and 3 (111) exceed the dimensions of protrusion 131; that is, the length of protrusion 131 does not exceed the length of the socket cavity, and the width of protrusion 131 does not exceed the width of the socket cavity, so as to facilitate the rapid and unobstructed vertical insertion of protrusion 131 through the socket. The reinforcing ring 8, when viewed from above, has an elliptical shape, and the center of the reinforcing ring 8 has an insertion hole with the same shape as protrusion 131. (The last sentence appears to be incomplete and possibly refers to a different socket.) 1. The shapes of the second socket 101 and the third socket 111 are the same as the shape of the cavity of the embedded hole. After the protrusion 131 passes through the lower fabric layer 11 and the sponge layer 10 in sequence and extends out of the upper fabric layer 9, the reinforcing ring 8 is then put on the protrusion 131, that is, the top of the protrusion 131 extends into the embedded hole. At this time, the reinforcing member composed of the reinforcing ring 8 and the protrusion 131 can firmly combine the conductive sheet 13, the lower fabric layer 11, the sponge layer 10 and the upper fabric layer 9 together, realizing the initial production assembly of the electrode patch.

[0038] The bump 131 mentioned is integrally molded on the conductive sheet 13. The bump 131 and the conductive sheet 13 are made of the same material, namely conductive silicone or nickel-plated copper. The reinforcing ring 8 mentioned is integrally molded on the upper fabric layer 9. The reinforcing ring 8 is made of, but is not limited to, chlorinated polyether or plastic materials such as PVC and PA, to enhance the overall structure of the upper fabric layer 9.

[0039] In this embodiment, the strong magnetic conductive button includes a female buckle 6 located on the upper fabric layer 9, a fixing piece 14 located in the middle of the conductive sheet 13, and a male buckle 7 that passes through the upper fabric layer 9, the sponge layer 10, the lower fabric layer 11, and the heating sheet 12 in sequence and fastens the female buckle 6 and the fixing piece 14 together. The female buckle 6 has an opening at its bottom for accommodating the male buckle 7. The top of the female buckle 6 is connected to a pair of insert rods 601 via a connecting shaft 602. The insert rods 601 extend vertically into the bottom shell 5, and the overall shape formed by the pair of insert rods 601 is a "U" shape. The fixing piece 14 is pressed onto the middle of the top of the conductive sheet 13. A through hole 141 is opened in the middle of the body of the fixing piece 14. A connecting post 701 passes through the middle of the top of the male buckle 7. The top of the connecting post 701 is fastened into the opening at the bottom of the female buckle 6, and the bottom of the connecting post 701 extends into the through hole 141.

[0040] The strong magnetic conductive button, consisting of female buckle 6, male buckle 7 and fixing piece 14, can act as a conductive component to electrically connect heating piece 12, conductive piece 13 and PCB board 3 together. This facilitates the heating and electrode functions of the electrode sticker through the button 2 on the control box. Female buckle 6, male buckle 7 and fixing piece 14 are all made of, but not limited to, copper or nickel-plated copper. The fixing piece 14 has a ring-shaped structure when viewed from above.

[0041] It should be noted that the heating element 12, conductive element 13, lower fabric layer 11, sponge layer 10 and upper fabric layer 9 mentioned above are provided with a perforation assembly at the top center for the male buckle 7 to pass through vertically; wherein, the perforation assembly includes a first perforation 902, a second perforation 102, a third perforation 112 and a fourth perforation. The perforation structure shape of the first perforation 902, the second perforation 102, the third perforation 112 and the fourth perforation is the same as the cross-sectional shape of the connecting post 701 of the male buckle 7. The cross-sectional shape of the connecting post 701 is a circular structure. The first perforation 902 is arranged at the top center of the upper fabric layer 9, the second perforation 102 is arranged at the top center of the sponge layer 10, the third perforation 112 is arranged at the top center of the lower fabric layer 11, and the fourth perforation is arranged at the top center of the heating element 12.

[0042] In the case of using the strong magnetic conductive button, a fixing piece 14 is pre-embedded in the middle of the top surface of the conductive sheet 13, and the cement adhesive layer 15 is arranged on the conductive sheet 13. Then, the male buckle 7 is arranged on the upper fabric layer 9. At this time, the connecting post 701 of the male buckle 7 passes through the first through hole 902, the second through hole 102, the third through hole 112 and the fourth through hole in sequence and extends into the through hole 141 on the fixing piece 14. That is, the connecting post 701 of the male buckle 7 connects the upper fabric layer 9, the sponge layer 10, the lower fabric layer 11 and the heating piece 12 together to form the electrode assembly layers. At this time, the electrode assembly layers and the conductive sheet 13 are connected together by the connecting post 701 and the fixing piece 14, thus completing the intermediate production assembly of the electrode.

[0043] Before the fabric heating electrode patch is pressed into shape, the upper fabric layer 9, the sponge layer 10, the lower fabric layer 11, and the conductive sheet 13 need to be joined together using reinforcing components to form a preliminary electrode patch. Specifically, the upper fabric layer 9, the sponge layer 10, and the lower fabric layer 11 are first pressed into their corresponding shapes using a pressing device. Then, the heating sheet 12 and the conductive sheet 13 are attached sequentially. Next, the middle parts of the upper fabric layer 9, the sponge layer 10, the lower fabric layer 11, the heating sheet 12, the hydrogel layer 15, and the conductive sheet 13 are joined together using a strong magnetic conductive button. Then, the preliminary electrode patch is pressed into shape using a pressing device, so that the upper fabric layer 9, the sponge layer 10, the lower fabric layer 11, the heating sheet 12, the hydrogel layer 15, the conductive sheet 13, the protrusion 131, the reinforcing ring 8, and the strong magnetic conductive button are firmly attached together to obtain the finished electrode patch. Finally, the bottom shell 5 is fastened onto the finished electrode patch using a female buckle 6 to obtain the fabric heating electrode patch.

[0044] The step of attaching the bottom shell 5 to the electrode patch using the female buckle 6 is as follows: the insertion rod 601 of the female buckle 6 extends into the bottom shell 5, and the insertion rod 601 is then electrically connected to the PCB board 3. The setting of the heating element 12 enables the electrode patch to have a heating function as a whole, and the setting of the conductive sheet 13 enables the electrode patch to have an electrode function as a whole.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
