Medical dressing patch and manufacturing method thereof

A medical dressing manufacturing method comprising:

• a first step of preparing a lower support film having a predetermined thickness;
• a second step of laminating a release film having a predetermined thickness on the lower support film;
• a third step of shaping the release film to have a shape divided into a fixed release film portion and a separable release film portion;
• a fourth step of laminating an adhesive sheet on the release film;
• and
• a fifth step of shaping the adhesive sheet to have a shape divided into an adhesive sheet portion for application and a separable adhesive sheet portion,
• wherein an adhesive layer is formed on the lower support film,
• wherein the adhesive sheet portion for application has larger adhesive force than the adhesive layer of the lower support film.

A medical dressing comprising:

• a release film;
• an adhesive sheet portion for application located on the release film, the adhesive sheet portion being configured to be attached to a skin;
• and
• a lower support film provided under the release film,
• wherein the release film comprises a fixed release film portion and a separable release film portion configured to be separated along an incision line formed in the fixed release film portion, wherein the incision line has a closed loop shape,
• wherein a predetermined region of the separable release film portion overlaps a lower surface of the adhesive sheet portion for application such that the separable release film portion is separated together with the adhesive sheet portion for application when being separated from the fixed release film portion,
• wherein an adhesive layer is formed at an upper surface of the lower support film such that the closed-loop shaped separable release film portion of the release film and the adhesive sheet portion are secured at a predetermined position due to the adhesive layer of the lower support film.
