[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dressing used for dressing and protecting an affected area in the medical field.

[0002]

2. Description of the Related Art An example of a conventional dressing 50 will be described with reference to FIG. 51 is a carrier film, 52 is a base film, 53 is a pad, and 54 is release paper. A pressure-sensitive adhesive layer 52a is formed on the entire back surface of the base film 52, and each of them has a substantially square planar shape. When using this dressing 50, remove the release paper 54 and
Is applied to the affected area to adhere the adhesive layer 52a of the base film 52 to the periphery of the affected area, and finally the carrier film 51 is peeled off from the base film 52. Since the base material film 52 is thin, the dressing thus attached does not hinder the free movement of the affected part.

By the way, in the above dressing 50, if only the base film 52 is used, it is extremely thin (usually,
(About 20 to 50 μm), it cannot be applied to the affected area well because it hangs down immediately. There is a certain degree of support there and it is easy to apply, so the carrier film 51
Is laminated on the base film 52. Therefore, once attached to the affected area, the movement of the affected area is hindered if the carrier film 51 is still attached, and thus it is peeled off as described above. The slit 55 is formed in the. Then, when the carrier film 51 is peeled off, a fingernail or the like is put in the slit 55 to raise the end of the carrier film 51, and the carrier film 51 is caught to be completely peeled off.

[0004]

By the way, in the case of the above-mentioned conventional example, even if an attempt is made to insert a nail into the slit 55, the slit 55 does not enter well and the carrier film 51 cannot be peeled off well. Further, since the processing for forming the slits 55 in the carrier film 51 is performed by pushing in a blade such as a cutter or pushing down while pushing and pulling, it is necessary to prevent the base film 52 on the back side of the carrier film 51 from being damaged. Therefore, it is necessary to control the position of the micron unit with a considerably high precision, the manufacturing equipment becomes large and expensive, and the speed of the manufacturing line cannot be increased.

In view of the above-mentioned circumstances, the present invention provides a dressing which allows the carrier film to be easily peeled off at the time of use, can be efficiently manufactured by a simple manufacturing facility, and can be easily aligned at a desired position and applied as desired. The purpose is to provide.

[0006]

In the dressing of the present invention, a carrier film is adhered and laminated on the surface of a substrate film, an adhesive layer is formed on the back surface of the substrate film, and a release paper is attached to the adhesive layer. In the temporarily bonded dressing, the base film is formed into a quadrangle, and the carrier film is
The base film has the same shape as a quadrangular main body portion and two protruding portions protruding in a substantially triangular shape from two opposing sides of the main body portion.
Surfaces of the knob pieces are adhered to the surfaces of the protruding portions and the part of the main body portion connected to the protrusions, respectively, at positions along the one edge of the base film located on the lower surface of the knob pieces. It is characterized in that a groove for folding is formed in. Further, in the present invention, it is also preferable that the pad is adhered to the adhesive layer on the back surface of the base film, and the release paper is temporarily adhered to the adhesive layer by sandwiching the pad.

[0007]

In the present invention, in the projecting portion of the carrier film, the end faces of the carrier film and the base film are not aligned and are misaligned, so that if the tab piece is folded back in the folding groove, the projecting portion of the carrier film will be The carrier film easily separates from the base film because it floats easily away from the edge of the base film, and the carrier film can be easily separated from the base film by pulling the tab piece as it is. You can The configuration of the present invention may include a step of adhering a tab piece to the protruding portion of the carrier film and a step of forming a folding groove in the tab piece, and the folding groove is formed by pressing an edge member. Since it can be formed and need not be cut, fine position control is not required. Therefore, the manufacturing equipment becomes simple and inexpensive, and the process control is easy, so that the manufacturing can be performed efficiently. Then, when applying, by holding the knob pieces with both hands and seeing through the carrier film in the central portion and looking at the affected area, it can be applied at the desired position.
