The present invention relates to an oral hemostasis and wound protection film that can adhere to the wound site of the oral cavity to delay or prevent fine bleeding and control the release of medicinal ingredients. The present invention includes a polyol, alcohol and a biodegradable polymer in a partially expanded state, and can absorb blood and abscesses at a local site and stop hemostasis. In addition, the film of the present invention has a high elongation rate and can maintain adhesion even after absorbing blood, saliva, and abscesses in the oral cavity, and the shape can be easily deformed depending on the local region where there are many bends. Therefore, even if it adheres to a local site for a long time, the feeling of foreign matter is low. The film of the present invention contains a disintegrating agent that dissolves and releases when reacting with blood and forms a fine channel serving as a drug release passage. The amount and size of the channel are adjusted to reduce the amount of drug discharged. Can be controlled. In the present invention, since the adhesive layer and the support layer are all disappeared and removed with the passage of time, it is not necessary for the patient to remove the transfer film adhered to the oral cavity by hand.
