preparation example Construction

[0149] In a more specific embodiment of the invention, the invention provides a hydrogel prepared with acrylamide (AM) as a monomer, methylenebisacrylamide (MBAA) as a crosslinking agent, and ammonium persulfate (APS) as an initiator , its preparation method comprises:

[0150] 1. Take about 1%~5% conductive filler (such as graphite powder) and 80~95% deionized water to form a mixed system;

[0151] 2. Stir for 30 minutes to 1 hour;

[0152] 3. Cool down to room temperature around 0-10°C, add 5% to 15% acrylamide (AM), 0.005% to 0.01% methylene bisacrylamide (MBAA), 0.02% to 0.05% ammonium persulfate (APS), and continue Stir for 10min to 20min to dissolve;

[0153] 4. Add 0.01%-0.04% tetramethylethylenediamine (TEMED), stir for 5-10 minutes; make a liquid conductive hydrogel.

[0154] The conductive hydrogel prepared by the above process is a single-network conductive hydrogel.

[0155] In another more specific embodiment of the present invention, the present invention als...

Embodiment 1

[0216] Such as figure 1 In the electrical stimulation patch shown, during use, two electrical stimulation patch products are attached to the surface of the human skin (indicated by the horizontal line at the bottom of the figure). The two electrical stimulation patches both have a lamellar structure, including a lamellar electrode layer 10 and a conductive polymer material layer 20 . The electrode layer 10 is realized by conductive fabric, which is woven by conductive fibers and has good conductivity; the conductive polymer material is made of conductive hydrogel material, which is made of hydrogel with 5% carbon-based conductive filler added. Then, the electrode layer 10 is arranged at the middle layer position of the electric stimulation patch, and one side of the electrode layer 10 is a discharge surface 101 facing the human body for discharge, and the discharge surface 101 is connected with the conductive polymer material layer 20 . A substrate layer 30 is provided on the...

Embodiment 2

[0218] Such as Figure 2-4 As shown, the cooperation relationship between the electrode layer 10 and the conductive hydrogel material 20 and the substrate layer 30.

[0219] First, if figure 2 As shown, the electrode layer 10 adopts a fabric electrode, and the fabric electrode can be attached to the surface of the conductive hydrogel material, and the discharge surface 101 is attached to the upper surface of the conductive hydrogel material 20, and then the substrate layer 30 of the drawing on the back is completely Wrapped for insulation protection.

[0220] Then, if image 3 The fabric electrode 10 shown is partly embedded in the conductive hydrogel material 20, coated with an insulating substrate layer 30 for wrapping, and through the cooperation of the substrate layer 30 and the conductive hydrogel material 20, complete sealing and protection of the fabric electrode is achieved.

[0221] or, if Figure 4 The textile electrode 10 shown is fully embedded in a conductive...

Abstract

The invention discloses an electrical stimulation patch which is of a lamellar structure. The patch comprises lamellar electronic epidermis and a conductive polymeric material layer, wherein the electronic epidermis is arranged in an intermediate layer of the electrical stimulation patch, and one side of the electronic epidermis is a discharge surface facing the human body. The discharge surface makes contact with the conductive polymeric material layer. The electric stimulation patch of the invention can uniformly stimulate the covered area, and the discharge effect is good.

Description

technical field [0001] The invention relates to an electric stimulation patch and its preparation method and application, in particular to an electric stimulation patch based on conductive hydrogel, its preparation method and application, and belongs to the technical field of medical devices. The invention mainly adopts the modification of the hydrogel material to realize the conductive performance, and obtains a high-quality, high-efficiency conductive hydrogel electric stimulation patch product through compounding. Background technique [0002] As a new type of treatment, electrical stimulation has a wide range of applications in the treatment of chronic diseases and the promotion of chronic wound healing. The electric stimulation patch is attached to the skin surface of the human body. By applying weak current stimulation, it can stimulate the attached human muscles, nerves and other parts to achieve blood circulation sedation, pain relief, wound healing and other purpose...
