Creative Contributions of the Methods of a Biomimetic Inventive Design of Novel Medical Drainage Materials Derived From Polyvinyl Alcohol Foam with Air Cavities Bioinspired by Avian Skeleton and Feather Rachises

Abstract

Traditional drainage materials used in a surgical treatment or in wound management are not good enough in both the effectiveness and efficiency because they may cause infection due to their characteristics. Therefore, a novel drainage material should be essential and designed to solve the problem. Avian skeleton and feather rachises may be good reference objects to mimic in designing a novel drainage material because its good cell structure which support a bird to fly safe and efficient. The term “nature-Bioinspired” is associated with a sequence of efforts to understand, synthesize and imitate any natural object or phenomenon either in a tangible or intangible form, which allows us to obtain improved insights into nature. Such inspirations can come through materials, processes, or designs. In this study, a new medical matrix derived from polyvinyl alcohol foam with air cavities inspired by avian skeleton and feather rachises for drainage medical treatments was designed, prepared, and characterized. Establishment of biomimetic biomedical inventive principles and a bio-inspired design-thinking method for innovative design of biomimetic medical devices and biomaterials were achieved. Also, the medical device (MD) unified problem-driven bioinspired evaluating approach was established to guide biomimetic design of biomaterials and the corresponding medical devices for various clinic applications.
