Abstract

(57) [Summary] [Purpose] To provide a medical adhesive tape or sheet that does not impair the air permeability and moisture permeability of the support itself as much as possible, eliminates fraying at the edges, and prevents peeling during use. provide. [Structure] By forming a plurality of wavy adhesive layers on a support having air permeability or moisture permeability, portions where no adhesive layer is formed are provided in a specific pattern. Preferably, the width of the adhesive layer is larger than the width of the unformed portion.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a medical adhesive tape or sheet that is applied to the skin surface.

0002

[Conventional technology]

Medical adhesive tapes or sheets are usually applied directly to the skin, but If the support or adhesive layer that makes up the tape does not have air permeability or moisture permeability, it may not be possible to apply it for a long time. During use, skin disorders such as stuffiness and rash may occur on the skin. subordinate Therefore, in order to provide breathability and moisture permeability, woven, knitted, or nonwoven fabrics are generally used as the support. Materials that have breathability or moisture permeability themselves, such as cloth or polyurethane film, The material used is a perforated plastic film with no air permeability. It is.

0003 On the other hand, the adhesive layer uses acrylic or rubber adhesives, and has good breathability and transparency. In order to impart moisture, an adhesive layer is applied to the entire surface of the support and then punctured with a needle-like object. or by applying it in straight lines in the length direction, or applying it in dots or grids. measures are being adopted.

[Problem that the idea aims to solve]

However, with such conventional medical adhesive tapes or sheets, the overall It may not be possible to provide sufficient air permeability or moisture permeability, or even if air permeability or moisture permeability is Even if the adhesive layer is not applied to the widthwise edges of the tape or sheet This often causes the support base material to fray from the edges or peel off from the skin surface during use. This may cause a phenomenon of bending.

[0005] Therefore, the present invention addresses the above-mentioned problems that the conventional medical adhesive tapes or sheets have. A support that is designed to solve a problem and has air permeability or moisture permeability. By forming the adhesive layer in a specific pattern, it is twice as effective as conventional products. It can exhibit the above breathability, and also prevents the support base material from fraying or peeling during use. We discovered that this can be prevented and came up with the present invention.

[0006]

[Means to solve the problem]

In other words, the present invention has a plurality of wavy adhesive layers on one side of an air-permeable support. A medical adhesive tape or sheet is provided.

[0007] The present invention will be explained below with reference to the drawings.

[0008] Figure 1 shows an example of the medical adhesive tape or sheet of the present invention, viewed from the adhesive layer side. FIG.

[0009] In FIG. 1, 1 is a support having air permeability or moisture permeability. breathable Examples of support materials include woven fabrics, nonwoven fabrics, knitted fabrics, etc., which have air permeability in themselves. Although the support and the base material itself are not breathable like regular plastic films, they can be perforated. Examples include supports that are made breathable through hole treatment. Also, vertical and horizontal A knitted fabric having elasticity is also preferably used. On the other hand, moisture-permeable support As the support, it is possible to use the above-mentioned breathable support, but for example, Plastics with relatively high moisture permeability, such as lyre-based films and polyurethane-based films, A support made of a stick film can also be used.

0010 In FIG. 1, reference numeral 2 denotes an adhesive layer provided on one side of the support 1, which is the skin surface. You can use acrylic or rubber adhesives that are less irritating when in contact with Wear. The adhesive layer 2 is formed by applying a plurality of stripes in a wavy manner as shown in the figure. Adhesive layer 2 The width and wave period can be set as appropriate, but the formation width of the adhesive layer 2 is determined by the adhesive layer 2. It is preferable to make the width larger than the width of the part where no . The width of the forming part is small Although it is possible to ensure air permeability and moisture permeability, it is difficult to secure enough bonding area, so Adhesion becomes poor.

[0011] The breathability of the medical adhesive tape or sheet of this invention is better than that of conventional products. Ru. Specifically, for example, the width of the adhesive layer 2 is 5 mm, and the width of the unformed portion is 0.5 to 1 mm. Medical adhesive of the present invention with a wave-like part period of 100 mm and an amplitude of 50 mm. The air permeability of the tape is 0.15-0.2 seconds/100cc, and the same support and adhesive 1.5 to 2 seconds/100c if the entire surface is coated with a compound and perforated with a needle-like object. c, and a clear improvement in air permeability was observed.

0012

[Effect of the idea]

As described above, the medical adhesive tape or sheet of the present invention can be applied to a piece of air permeable support. Since the adhesive layer is provided in a wavy manner on the surface, the inherent air permeability of the support is maintained as much as possible. It can be adhered to the skin surface well while maintaining its durability. Also, the frayed edges of the support Since there is no peeling phenomenon during use, discomfort to the user is also eliminated. It is something that
