Embodiment 1）

[0064] Prepare a polyurethane non-woven fabric with a thickness of 300 μm and a surface roughness of “26 μm” by extrusion processing so that the surface roughness becomes “11 μm”, and the 30% tensile load is 2.11 N / 15 mm in the width direction and 3.06 in the length direction. N / 15mm polyurethane non-woven fabric 2. An acrylic foamed adhesive layer 3 with a thickness of 30 μm was formed on one side of the nonwoven fabric, and it was formed into a rectangle with rounded corners of 8 cm in length and 11 cm in width. And the rounded hexagonal window part 5 of 5 cm long x 4.5 cm wide is formed in the center part.

[0065] Next, a rectangular window sheet 6 having a length of 8 cm x width of 5 cm and having a polyurethane adhesive layer 8 of 30 μm thick formed on one surface of a 20 μm thick urethane film 7 was prepared. It was pasted and fixed on the other side 9 of the nonwoven fabric 2 (with a surface roughness of 11 μm) so as to cover the above-mentioned window portion 5 , to ...

Embodiment 2）

[0067] Using a polyurethane non-woven fabric with a thickness of 300μm and a surface roughness of "26μm", the surface roughness is "13μm" by extrusion processing, and the 30% tensile load is 1.19N / 15mm in the width direction and 1.63 in the longitudinal direction. N / 15mm polyurethane non-woven fabric 2. Others are the same as in Example 1, and a catheter-fixing sticker 1 with a window is made.

Embodiment 3）

[0069] Using a polyurethane non-woven fabric with a thickness of 300μm and a surface roughness of "26μm", the surface roughness is "13μm" by extrusion processing, and the 30% tensile load is 1.71N / 15mm in the width direction and 2.26 in the longitudinal direction. N / 15mm polyurethane non-woven fabric 2. Also, the adhesive layer 3 is formed of an acrylic adhesive having a higher adhesive force than the adhesive of Example 1. Others are the same as in Example 1, and a catheter-fixing sticker 1 with a window is made.

Abstract

To obtain a windowed-catheter fastening patch that has sufficient adhesion and slipping properties as a fastening patch and in which satisfactory breathability and moisture permeability can be obtained at the window part. The window part (5) is formed on a non-woven fabric sheet (4) in which an adhesive layer (3) is provided on one surface of a non-woven fabric (2). A window-part sheet (6) is prepared in which a polyurethane adhesive layer (8) is provided on one surface of a urethane film (7). The window-part sheet (6) is bonded to the other surface side (9) of the non-woven fabric (2) so as to cover the window part (5) to obtain the windowed-catheter fastening patch (1). The other surface side (9) of the non-woven fabric (2) to which the polyurethane adhesive layer (8) provided to the urethane film (7) is bonded has a smooth surface having a surface roughness of 7 to 20 μm, allowing the window-part sheet (6) to be reliably bonded to the non-woven fabric sheet (4).

Description

technical field [0001] The present invention relates to an improvement of an adhesive material for fixing a catheter with a window for stably holding a puncture part of the catheter or the like. Background technique [0002] Conventionally, the punctured part into which the catheter is inserted is covered with a dressing (dressing) formed of a flexible plastic film. Thereby, the state of the puncture part is stably maintained, and contamination by bacteria or the like from the outside is prevented. [0003] The covering is provided with an adhesive layer on one side of a flexible plastic film reinforced with a carrier film, which adhesive layer is covered with a release paper. This covering is a structure in which the release paper is peeled off, the adhesive layer is attached to the punctured part, and the carrier film is peeled off. [0004] In such coverings, since a carrier film is used as a support for the sticker, it is usually a rigid and thick structure. Therefore...
