  • Patent number: 11344441
    Abstract: A reusable thermoplastic cast may include: a core material (10) having a net shape as a result of molding a synthetic resin elastomer into a net shape by of injection molding or press-working; and a structure (20), which consists of a polycaprolactone composite material and is molded to surround the outer circumferential surface of the core material (10) by insert injection. Example embodiments improve breathability by forming a cast in a net shape and provide a cast which is structurally sturdy and appropriate for mass production by molding the cast by, e.g., insert injection.

  • Patent number: 10632007
    Abstract: A thermoplastic cast, which is easy to reuse or implant, and a production method for same, are described. The cast includes a core material to which is attached polycaprolactone while being made in a mesh shape by the mutual crossing over and connecting of threads having a predetermined diameter, with the weaving of a plurality of strands of thin threads; and a structure which is made using a polycaprolactone composite and is formed so as to surround the outer part of the core material by means of insert injection. The patient experiences no discomfort despite the cast being structurally robust, because ventilation properties are improved due to the cast being formed in a mesh shape and because the structure, which is made using the polycaprolactone composite, is formed so as to surround the outer part of the core material by means of insert injection.
