Abstract

See full text

The present invention provides a dried amnion which is dried with maintaining tissues of a raw amnion and can be easily stored for a prolonged period of time. An amnion which is dried with maintaining cells and 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 by 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 with heating the amnion by microwaves irradiated from a microwave heating apparatus provided outside of the treatment vessel, and the amnion is characterized by retaining basement membranes and connective tissues which are constituents of the raw amnion.
