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. [Selection] Figure 1本発明は、口腔の創傷部位に付着して微細な出血を遅延または防止し、薬効成分放出を制御することができる口腔止血及び創傷保護フィルムに関連している。本発明は、ポリオール、アルコール及び生分解性ポリマー（ｂｉｏｄｅｇｒａｄａｂｌｅ ｐｏｌｙｍｅｒ）を部分膨張状態で含んで、局所部位の血液や膿瘍を吸収し、止血することができる。また、本発明のフィルムは、伸び率が大きくて、口腔内の血液、唾液及び膿瘍を吸収しても付着力を維持することができ、屈曲が多い局所部位に応じて形態の変形が容易になって、局所部位に長時間付着しても異物感が低い。また、本発明のフィルムは、血液と反応する時に溶解放出され、薬物放出通路となる微細なチャンネルを形成する崩壊剤を含んで、上記チャンネルの量と大きさを調節して、薬物排出量を制御することができる。本発明は、粘着層と支持体層が時間の経過に応じて、すべて消失して除去されるため、患者が手で口腔内に付着した伝達体フィルムを脱着する必要がない。【選択図】 図１
