Artificial hibernator and process for cold preservation of a human being or animal in a predetermined position

A process for cold preservation of the cadaver of a human being or animal, comprising:

• placing the cadaver in a desired final position;
• freezing said cadaver in a freezer at -30.degree. to -40.degree. C.;
• placing the frozen cadaver in a box of an artificial hibernator, comprising an outside multiple wall structure comprising two separate yet integral compartments including an upper fluid-tight compartment and a lower compartment enclosing a freezer unit, at least one of the walls of the structure being transparent;
• an internal box having box walls, said box being placed in the upper compartment, serving as a resting place for the being to be frozen and separated from the box walls by thermally insulating means;
• a door having a porthole provided with two panes between which a vacuum prevails and comprising a shaped seal able to assure fluid tightness between the door and said outside muliple wall structure;
• and means in the lower compartment for assuring a partial vacuum at least in the resting place and the porthole;
• maintaining, in the box, the temperature between -5.degree. and -25.degree. C. and a slight vacuum.
