Polymer film wound dressing - contg. protein, pref. casein (salt), and moisture-retainer, and opt. formed in situ.

摘要

Wound dressing consists of a polymer film contg. >=20 wt. % protein material (I) and >=20 wt. % incorporated moisture- retainer (II). Human and veterinary medicine, esp. in treating burns and to prevent flies settling on animal wounds, e.g. caused by castration or de-horning. Film can be applied directly to wounds, suppresses bleeding and promotes healing. Pref. (I) is casein (salt), but may be gelatine, collagen, keratin, silk or one-cell protein. Film-forming polymer may be PVA, PVAc or collidine. (II) may be polyhydroxylated cpds. Component ratio is non-critical, but a partic. clear film was formed with 30-80 wt. % casein, 1-10 wt. % PVA and 20-70 wt. % glycerol.
