Description

Technical Field

[0001] The utility model relates to the technical field of plasters, in particular to a flexible heating plaster. Background Art

[0002] Traditional heating plasters require the plaster to be preheated on a heating device in advance, so that the plaster can be softened before being attached to the skin to increase the speed of drug absorption. The problem is that it needs to be preheated in advance, and the preheating time and temperature are difficult to control, which makes it difficult to control the degree of melting of the ointment. In addition, during use, the drug cannot be heated continuously, resulting in poor use effect. To address this problem, some studies have set a heating layer that can generate heat continuously on the plaster to achieve continuous heating, but due to the unreasonable structure and layout of the heating layer, the comfort level is poor during use.

[0028] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0029] Example 1

[0030] See also Figure 1 and Figure 2 , a flexible heating plaster of this embodiment, the structure of the heating plaster comprises a base layer 1, a drug layer 2 arranged on the base layer 1, and a heating layer 3 arranged between the base layer 1 and the drug layer 2;

[0031] Wherein, base layer 1 is the first base layer;

[0032] The heating layer 3 may be a carbon-based material or an alloy material. In this example, the heating layer 3 is an electric heating wire having a positive electrode end and a negative electrode end.

[0033] As a preferred embodiment, the electric heating wire is embroidered on the surface of the first base layer close to the drug layer 2 by an embroidery machine;

[0034] As a preferred embodiment, the electric heating wire is made of alloy wire, carbon fiber wire, carbon paste or graphene.

[0035] The surface of the electric heating wire is provided with an insulating layer;

[0036] A universal interface 4 is provided on the base layer 1, which is used to connect the two electrode ends of the heating layer 3 to an external power source to form a loop.

[0037] Specifically, the distribution area of ​​the drug layer 2 does not exceed the range of the distribution area of ​​the electric heating wire.

[0038] Specifically, the diameter of the electric heating wire is 0.2-1 mm.

[0039] Specifically, the electric heating wires are evenly distributed in a spiral shape.

[0040] Specifically, the universal interface 4 may adopt a TYPE-C interface.

[0041] Specifically, the universal interface 4 is bonded or anchored on the base layer 1 through a locking member.

[0042] Specifically, the first base layer is a non-woven fabric layer.

[0043] The flexible heating plaster of this embodiment has a paste-like structure of the drug layer 2. When in use, the flexible heating plaster is attached to the part of the human body to be treated so that the drug layer 2 contacts the skin. The universal interface 4 is connected to an external power source (such as a power bank, etc.), and the electric heating wire is heated, so that the paste-like drug layer 2 gradually softens and melts into the base layer, so that the plaster adheres to the skin, and the softened drug is absorbed by the human body.

[0044] Because the motor heat wire is embroidered on the surface of the non-woven fabric, the plaster is softer, which greatly reduces the foreign body sensation of the human body and improves the comfort level during use. At the same time, it realizes heating at any time and improves the continuity of auxiliary heating, which greatly improves the convenience of using the plaster.

[0045] It can be understood that the power of the heating wire is set according to the temperature required for the paste to soften, and preferably the electric heating wire is maintained at 30°C.

[0046] Example 2

[0047] The flexible heating plaster of this embodiment has the same structure as that of the embodiment 1 except that:

[0048] Base layer 1 is the second base layer;

[0049] The second substrate layer is a plastic layer;

[0050] The heating layer 2 is a metal etching circuit, which is formed on the surface of the second substrate layer close to the drug layer by metal etching, and the metal etching circuit has two positive and negative electrode ends;

[0051] The metal etching circuit is formed by etching a copper foil, and the copper foil is adhered to the second base layer;

[0052] The thickness of the metal etching circuit is 3 to 35 um;

[0053] The metal etching circuits are evenly distributed in a spiral shape;

[0054] The surface of the metal etching circuit is provided with an insulating layer;

[0055] The distribution area of ​​the drug layer 2 does not exceed the range of the distribution area of ​​the metal etching circuit.

[0056] The working principle of the second embodiment is similar to that of the first embodiment. The drug layer 2 is in a paste structure. When in use, the flexible heating plaster is attached to the part of the human body to be treated so that the drug layer 2 contacts the skin. The metal etching circuit generates heat by connecting to an external power source (such as a power bank) through the universal interface 4, which gradually softens the paste drug layer 2 and melts into the base layer, so that the plaster adheres to the skin and the softened drug is absorbed by the human body.

[0057] Since the thickness of the metal etching circuit is very small, the plaster is softer, which greatly reduces the foreign body sensation of the human body and improves the comfort level during use. At the same time, it realizes heating at any time and improves the continuity of auxiliary heating, which greatly improves the convenience of using the plaster.

[0058] It can be understood that the power of the heating wire is set according to the temperature required for the paste to soften, and preferably the electric heating wire is maintained at 30°C.

[0059] Those skilled in the art can understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
