Abstract
A keratinous wound healing material, preferably derived from the hair of the patient or a compatible donor. Keratin powder can be derived from hair using processing steps including cleaning, suspending in a liquid carrier, homogenizing and removing the liquid. The keratinous material may be applied to the wound in powder form. The keratin can also be applied in sheet form. The keratinous material can be bound with polymeric binder and formed into a sheet by pouring the polymer/binder solution into a mold and flashing off the solvent.
Claims67
A process for creating a wound dressing sheet comprising the steps of:
- providing a polymer binder material;
- providing a solvent;
- dissolving said polymer binder in said solvent, creating a polymer binder solution;
- providing keratin powder;
- suspending said keratin powder in said polymer binder solution, creating a keratin suspension;
- casting said suspension into a sheet;
- and
- flashing off said solvent.
A method for treating a wound in a patient comprising applying keratin to said wound, wherein said keratin is obtained from human hair.
A method for treating a wound as in a patient comprising applying keratin to said wound, wherein said keratin is in sheet form comprising keratin bound together with a polymeric binder.
A method for treating a wound in a patient comprising applying keratin to said wound, wherein said keratin is created by a process comprising:
- comminuting hair into a keratin powder;
- and
- sterilizing said keratin powder.
A wound dressing comprising:
- a sheet comprising keratin powder bound with a polymeric binder.
A method for treating a wound in a patient comprising:
- applying keratin obtained from hair to said wound.
A wound dressing comprising keratin powder, wherein said keratin is obtained from hair.
A wound dressing created by a process comprising:
- comminuting hair into a keratin powder;
- and
- sterilizing said keratin powder.
A keratin wound dressing sheet created by the process comprising:
- forming a suspension by combining a polymeric binder, a solvent, and a keratin powder obtained from hair;
- casting said suspension into a sheet;
- and
- flashing off said solvent.
