▎ 摘　　要

NOVELTY - The ring has a ring main body for containing bacterial cellulose and graphene and/or graphene oxide as an additive material, where the graphene and/or graphene oxide contain nitrogen, sulfur, phosphorus, boron, fluorine, and chlorine. A lower base contacts an abdominal skin around a newborn's umbilical cord. An inner wall encloses the umbilical cord to contact a portion of the umbilical cord that starts from the abdominal skin about an axis of the umbilical cord, where height of the ring main body is in a specified range. USE - Ring for newborn umbilical cord care to prepare antimicrobial drugs in pharmacy and pharmaceutical field. ADVANTAGE - The ring enables an umbilical cord to dry quickly and separate in a shorter time due to hydrophilic nature of bacterial cellulose. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for producing a ring for neonatal umbilical cord care.
