Abstract

PURPOSE: To enable peeling of an adhesive pad body simply by a light force without lowering an adhering force by forming a constricted part on the periphery thereof. CONSTITUTION: In an adhesive pad A, a soft thin adhesive pad body 1 is arranged to make up a main body thereof and an adhesive part is formed on the external part thereof. One constricted part 2 or more is formed on the periphery of the adhesive pad body 1. The constricted part 2 may be given a smoothly curved shape. For example, four constricted parts 2 are arranged on the peripheral part to divide the adhesive pad body 1 into three parts (a) to (c) so that the constricted parts 2 are formed in a smoothly curved shape. When the adhesive pad body 1 is removed after applied on a skin surface of a human body, it can be peeled off by a minimum force in the direction vertical to a curved surface of the skin surface of the human body to the position of the constricted parts 2. The adhesive pad body 1 is turned back and peeled centering the constricted parts 2 even when passing through the constricted parts 2 thereby enabling minimizing of the force in the direction vertical to the skin surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive pad for a low frequency treatment device which is used by being attached to a human body.

[0002]

2. Description of the Related Art Conventionally, there are various adhesive pads A of a low-frequency therapeutic device used by being attached to a human body as shown in FIG. 8 to FIG.
The outer diameter of the adhesive pad body 1 is linear or curved, and the adhesive surface of the outer surface is directly adhered to the skin surface a of the human body.

[0003]

However, in the conventional example as described above, when the adhesive pad body 1 is attached to the curved surface of the skin surface a of the human body and then peeled off, one end of the adhesive pad body 1 is removed. Is to be peeled off by holding it with a finger, but up to the central portion of the adhesive pad body 1, as shown in FIG. 12 (a), is called a force F in the direction perpendicular to the curved surface of the skin surface a of the human body. It can be removed with the minimum force, but when it passes through the center, it is removed in the direction of the force F'as shown in FIG. 12 (b), and it is perpendicular to the curved surface of the skin surface a of the human body. However, there is a problem in that the adhesive pad A cannot be removed smoothly due to the addition of extra resistance.

FIG. 13 shows the change in peeling force at the above points. As can be seen from FIG. 13, it can be said that the peeling force F increases after passing the top on the curved surface of the skin surface a of the human body, which makes it difficult to remove.
In addition, since the adhesive pad body 1 itself has a shape like an integrated body, when it is attached obliquely to the curved surface of the human skin surface a, the end surface of the adhesive pad body 1 is difficult to follow along the curved surface during use. There was a problem of floating.

The present invention is intended to solve the above-mentioned problems, and an object thereof is to provide an adhesive pad for a low-frequency therapeutic device which can be easily peeled off with a light force when removing it without lowering the adhesive force. To do.

[0006]

In order to achieve the above object, the present invention is characterized in that one or more constricted portions are provided on the periphery of an adhesive pad body attached to a human body. Also, the shape of the constricted portion may be a smooth curved line.

[0007]

However, by providing one or more constricted portions, the adhesive pad body can be attached to the curved surface of the human body's skin surface without significantly reducing the adhesive strength. In addition, when peeling off the adhesive pad main body stuck on the curved surface of the human body, the adhesive pad main body can be folded back at the constricted part and peeled off, and the minimum force of the force perpendicular to the curved surface constantly It can be peeled off with. Even if it is attached diagonally to a curved surface, the presence of the constricted portion can partially resemble a shape in which the adhesive pad body is divided, and it acts like a separate adhesive pad body and has a curved surface of the human body. It can be adhered to and can be attached without the edge rising.

Further, by making the shape of the constricted portion into a smooth curved shape, the adhesive pad main body can be smoothly peeled off.

[0009]

The present invention will be described below in detail based on the illustrated embodiments. The adhesive pad A in the present invention is mainly composed of a flexible thin plate-like adhesive pad body 1, and can be attached to the skin surface a of the human body through an adhesive portion provided on the outer surface. Has become. One or more constricted portions 2 are provided on the periphery of the adhesive pad body 1. The constricted portion 2 may be formed in a smooth curved shape.

FIG. 1 shows an example in which the adhesive pad body 1 is provided with four constrictions 2 in the peripheral portion thereof and the adhesive pad body 1 is divided into three parts a to c. Here, the shape of the constricted portion 2 in this embodiment has a smooth curved shape. 2 to 5 show an example in which one constricted portion 2 is provided near the center of the adhesive pad body 1 on the left and right sides, and the adhesive pad body 1 is divided into two parts d and e. . Here, the constricted portion 2 in the embodiment shown in FIG. 2 has a linear shape, and FIGS.
In the embodiment shown in (1), the constricted portion 2 has a smooth curved shape.

Therefore, the adhesive pad body 1 as described above
When removing after attaching to the curved surface of the skin surface a of the human body,
As shown in FIG. 6A, it can be peeled up to the position of the constricted portion 2 with a minimum force of a force F in the direction perpendicular to the curved surface of the human skin surface a. As shown in FIG. 6 (b), the adhesive pad main body 1 can be easily folded around the constricted portion 2 and peeled off even after passing through the constricted portion 2. It can be peeled off with a minimum force of a force F in the direction perpendicular to the curved surface of the surface a.

Further, due to the presence of the constricted portion 2, the adhesive pad main body 1 can be divided into a plurality of parts, and each part in the divided state is in close contact with the curved surface of the skin surface a of the human body, It can be flexibly and firmly attached along the skin surface a without the edges of the skin surface a rising up. FIG. 7 shows the difference in the transition of the peeling force when peeling the adhesive pad body 1, FIG. 7A shows the transition of the peeling force of the adhesive pad body 1 of FIG. 2, and FIG. 5 shows a change in peeling force of the adhesive pad body 1 of FIG.

In the case where the shape of the constricted portion 2 is a smooth curved line, the transition of the peeling force is shown in FIG. 5 as can be seen from the difference in the transition of the peeling force shown in FIG. Since the main body 1 is changing more smoothly, it can be said that when actually peeling off the substantially gourd-shaped adhesive pad main body 1 in plan view shown in FIG. 5, it can be smoothly and smoothly peeled off.

[0014]

According to the present invention, since one or more constricted portions are provided on the periphery of the main body of the adhesive pad to be attached to the human body,
It is possible to attach the adhesive pad body to the curved surface of the human body's skin surface without significantly reducing the adhesive strength, and when peeling off the adhesive pad body attached to the curved surface of the human body skin surface. In addition, the adhesive pad body can be peeled off by folding it back at the constricted portion, and can be peeled off continuously with a minimum force of a force perpendicular to the curved surface. Even if it is attached diagonally to a curved surface, it can be made to resemble a partially divided adhesive pad body due to the presence of a constricted portion, and it functions as a separate adhesive pad body and can be used as a curved surface of the human body. It can be adhered to and adhered without causing the edges to rise.

Further, when the shape of the constricted portion is made into a smooth curved line, the force at the time of peeling off the adhesive pad body acts in a distributed manner without partially acting on a part of the adhesive pad body. This means that the adhesive pad body can be peeled off smoothly when peeled off.
