US 2026/0295127 A1 · MEDICAL FILM AND PRODUCTION METHOD THEREFOR

Abstract

A medical film containing a bioabsorbable polymer compound and PGA dispersoids or aggregates of PGA particles. A number-average molecular weight of the polymer is 7,500 or more and 100,000 or less, an average particle size of the particles is 1 μm or more and 60 μm or less, the content of the PGA dispersoids per 100 parts by weight of the bioabsorbable polymer compound is 2 parts by weight or more and 40 parts by weight or less, and a coefficient of variation CV of the number of particles contained in rectangular regions is 0.6 or less, where the coefficient of variation CV is determined from the number of particles measured in each of 16 rectangular regions with a size of 5 mm×4 mm set so as not to overlap with each other on a surface of the medical film.

A medical film comprising:

a bioabsorbable polymer compound;
and
polyglycolic acid dispersoids that are particles containing a polymer having a constituent unit derived from glycolic acid or aggregates of the particles, wherein
a number-average molecular weight of the polymer of the polyglycolic acid dispersoids is 7,500 or more and 100,000 or less,
an average particle size of the particles is 1 μm or more and 60 μm or less,
a content of the polyglycolic acid dispersoids per 100 parts by weight of the bioabsorbable polymer compound is 2 parts by weight or more and 40 parts by weight or less, and
a coefficient of variation CV of the number of particles contained in rectangular regions is 0.6 or less, where the coefficient of variation CV is determined from the number of particles measured in each of 16 rectangular regions with a size of 5 mm×4 mm set so as not to overlap with each other on a surface of the medical film.
