Abstract
Abstract This invention relates to modified starch gel seals for ostomy patients that can be produced in relatively high purity and at low cost, composed essentially of gelatinized starch, with or without a plasticizer such as glycerol or the like and glyoxal. The seal has a low rate of solubility that can be controlled and provides protection for the skin surrounding the stoma. One small size stoma opening in the center of the seal can be stretched and will fit larger size stomas without causing strangulation of the stoma. The gels can also act as a vehicle for medicinals, odorcontrol materials, or water retardants and can be made of multiple layers to satisfy the various needs of the patient.
