DRIED AMNION AND METHOD FOR DRYING TREATMENT OF AMNION

摘要

Disclosed is a dried amnion which is dried while maintaining the tissues of a raw amnion and can be stored in a simple manner for a prolonged period of time. An amnion which is dried while maintaining the cellular tissues of a raw amnion can be produced by repeating a pressure-reducing operation and a pressure-recovery operation several times, the pressure-reducing operation comprising continuously heating a raw amnion placed in a treatment vessel with a far-infrared heater provided in the treatment vessel and reducing the pressure of the inside of the treatment vessel, and the pressure-recovery operation comprising recovering the reduced pressure of the inside of the treatment vessel while heating the amnion with a microwave irradiated from a microwave heating apparatus provided outside of the treatment vessel. The amnion is characterized by retaining basement membranes and connective tissues which are constituents of the raw amnion.
