  • Patent number: 11213615
    Abstract: Described herein is a composition for submucosal injection comprises a biocompatible modified starch and a pharmaceutically acceptable carrier for injection. The biocompatible modified starch is in an amount ranging from 0.2 wt % to 50 wt % of the total weight of composition. The biocompatible modified starch is selected from one or more of the group consisting of: etherified starches, esterified starches, cross-linked starches, pre-gelatinized starches, graft starches and composite modified starches, which has a molecular weight ranging from 3,000 to 2,000,000 daltons, a water absorbency capability of at least twice of its own weight, and a particle size from 500 nm to 1000 ?m. The viscosity of the composition ranges from 9 mPa·s to 150,000 mPa·s at 25° C. The present disclosure also provides a combination reagent for submucosal injection, comprising the above-mentioned biocompatible modified starch and the pharmaceutically acceptable carrier for injection.

  • Patent number: 9687501
    Abstract: A modified starch material is arranged for biocompatible hemostasis, biocompatible adhesion prevention, tissue healing promotion, absorbable surgical wound sealing and tissue bonding, when applied as a biocompatible modified starch to the tissue of animals. The modified starch material produces hemostasis, reduces bleeding of the wound, extravasation of blood and tissue exudation, preserves the wound surface or the wound in relative wetness or dryness, inhibits the growth of bacteria and inflammatory response, minimizes tissue inflammation, and relieves patient pain. Any excess modified starch not involved in hemostatic activity is readily dissolved and rinsed away through saline irrigation during operation. After treatment of surgical wounds, combat wounds, trauma and emergency wounds, the modified starch hemostatic material is rapidly absorbed by the body without the complications associated with gauze and bandage removal.
