It is intended to provide a medical film which is excellent in biocompatibility and bioabsorbability and has a high strength in suturing and bonding. A reinforcing material (12) made of a biodegradable and bioabsorbable polymer is located in a gelatin solution. After allowing the solution to penetrate into the reinforcing material (12), the gelatin is dried. Thus, the gelatin having penetrated into the reinforcing material (12) sets to gel to thereby form a gelatin film (11) so that a medical film (1 )composed of the reinforcing material (12) and the gelatin film (11) integrated together can be obtained. It is preferable that the above-described gelatin film (11) is a crosslinked gelatin film.
La présente invention concerne un film médical qui présente une très bonne biocompatibilité, une très bonne bioabsorbabilité et une grande résistance à la suture et à la liaison. Un matériau de renfort (12) constitué d'un polymère biodégradable et bioabsorbable est placé dans une solution de gélatine. Après avoir fait pénétré la solution dans le matériau de renfort (12), la gélatine est séchée et elle se transforme donc en gel, ce qui permet de former un film de gélatine (11), de façon à obtenir un film médical (1) composé du matériau de renfort (12) et du film de gélatine (11) conjointement intégrés. Ledit film de gélatine (11) est de préférence un film de gélatine réticulé.
