Description

Technical Field

[0001] The utility model belongs to the technical field of iontophoresis, and particularly relates to a connector for an iontophoresis patch and an iontophoresis patch. Background Art

[0002] Electroporation is a process of forming temporary and reversible hydrophilic pores in lipid bilayers such as cell membranes by using an instantaneous high-voltage pulsed electric field to increase the permeability of cells and tissue membranes. Iontophoresis is a physical process in which an ion current diffuses directionally in a medium driven by an electric field force. By applying a fluid containing a charged active ingredient to the skin and covering the fluid with an electrode sheet of an iontophoresis device, while making another electrode sheet contact another skin position of the body, the charged active ingredient is driven to rapidly penetrate into the skin under the energized state by using the principle of like charges repelling each other, thereby achieving the purpose of transdermal drug delivery in the medical field or the purpose of skin care in the beauty field. However, iontophoresis introduction devices usually use a device with a handle to move around on the skin surface, resulting in low introduction efficiency and inconvenient operation.

[0003] In recent years, beauty instrument products and technologies presented in the form of electronic masks have developed relatively rapidly. The Chinese invention patent with the publication number CN117138235A discloses an electronic mask and its manufacturing method. The electrode area of this application's electronic mask uses silver paste as the electrode material. When the positive silver electrode is energized after applying a beauty essence solution, an electrolysis reaction may occur, releasing silver ions, thus causing product use risks. The connection between the positive silver electrode and the wire is easily contaminated by the beauty essence solution, resulting in problems such as short circuit, oxidation and electrolysis of metal components, and difficulty in cleaning. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art, and provides a new technical solution for a connector for an iontophoresis patch and an iontophoresis patch.

[0005] According to the first aspect of the present application, there is provided a connector for an iontophoresis patch. The iontophoresis patch includes a substrate, a first electrode and a wire layer. The flexible substrate has a first electrode surface facing away from the facial skin; the first electrode is a positive electrode; at least one mesh-shaped first electrode is printed on the surface of the first electrode surface, and the first electrode is connected to a control unit through the wire layer. The connector is used to connect the first electrode and the wire layer, and includes a bottom layer, a connector body and a covering layer;

[0006] The bottom layer is an insulating layer, and the bottom layer is printed on the first electrode surface; the first end of the bottom layer covers the surface of the first electrode, and a first hollow is provided at the first end of the bottom layer;

[0007] The conductive line layer is printed on the bottom layer, and the conductive line layer has a first end facing the first electrode;

[0008] The connector body is printed on the bottom layer and the wire layer, and the first end of the connector body partially or completely covers the first hollow, so that the connector body is connected to the first electrode through the first hollow; the second end of the connector body covers the first end of the wire layer, so that the second end of the connector body is connected to the wire layer;

[0009] The covering layer is an insulating layer, and the covering layer covers the bottom layer, the connector body, and the wire layer.

[0010] Optionally, the connector body is made of conductive graphite or conductive carbon paste.

[0011] Optionally, the shape of the first hollow is circular, One of the following shapes: circle, polygon, or star.

[0012] Optionally, the surface areas of the bottom layer and the covering layer are larger than the surface area of the wire layer, and the bottom layer and the covering layer respectively wrap opposite sides of the wire layer to form an insulating layer of the wire layer.

[0013] Optionally, the material of the bottom layer is at least one of polyurethane, acrylate, epoxy resin, and polyamide resin.

[0014] Optionally, the covering layer is made of at least one of polyurethane, acrylate, epoxy resin, and polyamide resin.

[0020] One of the technical effects of this application is:

[0021] In the embodiments of the present application, the conductor layer and the first electrode are connected via a connector made of conductive graphite or conductive carbon paste. This effectively prevents the connection between the conductor layer and the first electrode from being exposed and contaminated by beauty serums or liquids, leading to oxidation and electrolysis reactions, thereby effectively preventing contamination of the beauty serums or liquids. Furthermore, the conductor layer is insulated and wrapped with a base layer and a cover layer, directing electrical energy directly to the center of the first electrode. The electrical energy diffuses outward from the center of the first electrode, resulting in a more uniform distribution of electrical energy. This prevents the conductor layer from connecting to the edges of the first electrode, which could lead to higher electrical energy near the power source and gradually attenuate at the far end, resulting in uneven electrical energy distribution.

[0022] Furthermore, the flexible PCB and cord containing the metal conductors are wrapped with a base layer and a cover layer to prevent oxidation and electrolysis reactions of the metal conductors if contaminated with a beauty serum or liquid medicine. Simultaneously, the base layer and cover layer physically separate the first electrode connection contact (i.e., the positive electrode contact), the second electrode connection contact (i.e., the negative electrode contact), and the conductors to prevent short circuits between the first electrode connection contact, the second electrode connection contact, and the conductors due to contamination with the beauty serum or liquid medicine.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0037] According to the first aspect of the present application, referring to Figures 1 to 5 , a connector for an iontophoretic patch is provided. The iontophoretic patch includes a substrate 1, a first electrode 3, and a wire layer 42. The flexible substrate 1 has a first electrode surface facing away from the facial skin and a second electrode surface facing the facial skin, and the substrate 1 has an interface portion 101; the first electrode 3 is a positive electrode; at least one mesh-shaped first electrode 3 is printed on the surface of the first electrode surface, and the first electrode 3 is connected to a control unit (not shown in the figure) through the wire layer 42. The connector is used to connect the first electrode 3 and the wire layer 42, and includes a bottom layer 41, a connector body 43, and a covering layer 44;

[0038] The bottom layer 41 is an insulating layer, and the bottom layer 41 is printed on the first electrode surface; the first end of the bottom layer 41 covers the surface of the first electrode 3, and a first hollow 411 is provided at the first end of the bottom layer 41;

[0039] The wire layer 42 is printed on the bottom layer 41, and the wire layer 42 has a first end facing the first electrode 3;

[0040] The connector body 43 is printed on the bottom layer 41 and the wire layer 42, and the first end of the connector body 43 partially or completely covers the first hollow 411, so that the connector body 43 is connected to the first electrode 3 through the first hollow 411; the second end of the connector body 43 covers the first end of the wire layer 42, so that the second end of the connector body 43 is connected to the wire layer 42;

[0041] The covering layer 44 is an insulating layer, and the covering layer 44 covers the bottom layer 41, the connector body 43, and the wire layer 42.

[0042] In the embodiment of the present application, the joint body 43 made of conductive graphite or conductive carbon paste is used to connect the wire layer 42 and the first electrode 3, which can effectively prevent the connection between the wire layer 42 and the first electrode 3 from being exposed, and prevent the oxidation and electrolysis reactions caused by the contamination of the beauty essence or liquid medicine, thus effectively avoiding the contamination of the beauty essence or liquid medicine. Moreover, the wire layer 42 is insulated and wrapped by the bottom layer 41 and the covering layer 44, and the electric energy is directly conducted to the middle part of the first electrode 3. The electric energy diffuses outward from the middle part of the first electrode 3, and the electric energy is relatively uniform, which can prevent the connection between the edge parts of the wire layer 42 and the first electrode 3, and avoid the situation that the electric energy is strong at the proximal end close to the power supply and gradually attenuates at the distal end, resulting in uneven distribution of electric energy.

[0043] Furthermore, the flexible PCB and the flexible wire 8 containing metal conductors are wrapped by the bottom layer 41 and the covering layer 44 to prevent the oxidation and electrolysis reactions of the metal conductors after being contaminated by the beauty essence or liquid medicine. At the same time, the connection contacts (i.e., the positive electrode contact 31) of the first electrode 3, the connection contacts (i.e., the negative electrode contacts) of the second electrode 5, and the conductors are physically separated by the bottom layer 41 and the covering layer 44 to prevent short circuits from occurring between the connection contacts of the first electrode 3, the connection contacts of the second electrode 5, and the conductors due to the contamination of the beauty essence or liquid medicine.

[0044] Exemplarily, a first opening is provided at the position of the base 1 corresponding to the eye, and a second opening is provided at the position of the base 1 corresponding to the mouth.

[0046] Optionally, the shape of the first hollow 411 is one of a circle, a circle, a polygon, and a star. The shape of the first hollow 411 is reasonably set, which helps to achieve the stability of the electrical connection at the end of the first electrode 3.

This helps to achieve the insulation of the wire layer 42 and ensure the stability of the wire layer 42.

[0048] Optionally, the bottom layer 41 is made of at least one of polyurethane, acrylate, epoxy resin, and polyamide resin. This helps to ensure that the bottom layer 41 has a good insulation effect.

However, when silver is exposed to a beauty serum or medical drug solution and then fed into the positive electrode, the silver wire may undergo an electrolytic reaction, releasing silver ions, which can create product risks. In this embodiment, the conductive wire layer 42 is wrapped with a base layer 41 and a cover layer 44, both of which are insulating layers. Furthermore, the connector body 43, printed with conductive graphite or conductive carbon paste, is connected to the exposed first electrode 3, effectively preventing exposure of the silver conductor.
