Embodiment 1

[0147] Example 1: A skin patch with a conductive cap connected to a power source through magnetic interaction

[0148] In this embodiment, the magnetic connector end of the external power supply is magnetically attracted to the magnetic ball 5 and contacts the conductive cap 4 to form an electrical connection. The detailed structure of the conductive cap is as figure 1 shown. The current is conducted to the electrode sheet 3 through the conductive cap to form an electrical circuit.

[0149] Wherein, the backing layer 1 fixes the electrode sheet on the same plane through the adhesive layer 2, and the backing layer 1 is insulated to avoid current leakage of the electrode sheet; the protective layer 7 is the packaging protection for the gel layer 6, and is peeled off before use; The gel layer 6 is a fixed carrier for the active ingredients.

[0150] and, in figure 2 In the shown embodiment, the lower surface of the large head end of the conductive cap is in contact with the ...

Embodiment 2

[0151] Example 2: A skin patch in which the conductive cap is connected to the power supply through buckles

[0152] In this embodiment, the connector end of the external power supply is bayonet-connected with the conductive cap 4 to realize electrical connection. The current is conducted to the electrode sheet 3 through the conductive cap to form an electrical circuit.

[0153] Wherein, the backing layer 1 fixes the electrode sheet on the same plane through the adhesive layer 2; the backing layer 1 is insulated to avoid current leakage of the electrode sheet; the protective layer 7 is the packaging protection for the gel layer 6, and is peeled off before use; The adhesive layer 6 is a fixed carrier for active ingredients.

[0154] and, in Figure 4 In the shown embodiment, the lower surface of the large end of the conductive cap is in contact with the upper surface of the electrode sheet; Figure 5 In the illustrated embodiment, the upper surface of the large end of the co...

Embodiment 3

[0155] Embodiment 3: The skin sticking film that conductive cap is connected with power supply through colloid

[0156] In this embodiment, the connector end of the external power supply is viscously connected with the conductive glue 5 . The current is conducted to the electrode sheet 3 through the conductive glue to form an electrical circuit, such as Figure 6 shown.

[0157] Wherein, the backing layer 1 fixes the electrode sheet on the same plane through the adhesive layer 2; the backing layer 1 is insulated to avoid current leakage of the electrode sheet; the protective layer 7 is the packaging protection for the gel layer 6, and is peeled off before use; The adhesive layer 6 is a fixed carrier for active ingredients.

Abstract

The invention relates to a skin patch for transdermal iontophoresis drug delivery. Specifically, the skin patch includes a top-down laminated structural layer. The structural layer includes a backinglayer, a bonding layer, an electrode layer, a gel layer and a protective layer (peeling layer), the bonding layer is used to bond the backing layer and the electrode layer, the electrode layer includes N mutually independent electrode films, the gel layer contains active ingredients to be permeated into skin. And the skin patch includes M conductive caps which are distributed on the mutually independent electrode films, and the conductive caps are used to electrically connect a power supply with the electrode films, wherein M and N are positive integers greater than or equal to 2. The skin patch can be quickly connected with an ion electricity generating device, the use and operation are convenient, the possibility of drug contamination in a whole process does not exist, and industrialization can be conveniently achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a skin patch for transdermal iontophoresis drug delivery. Background technique [0002] Everyone has a love for beauty. With the continuous progress of human civilization and the improvement of economic level, people, especially women, pay more and more attention to their own appearance. Among them, skin care, as an important part of beauty, occupies most of women's beauty consumption. Skin care has become a science in modern times.
