Definition of a pure mate

Do you know the definition of a pure mate?
I just saw it in a Chess article from a Chess problem which was titled "Pure mate."
When a King is placed in an open area (at least one square away from any edge of the board), it can only move to eight squares around him:
8 possible moves for the King
The meaning of a pure mate is that for each of the eight squares around the black King, there is exactly a reason why the King cannot move to any of them as shown in the following graphic:
If all units of the mating side, with the possible exception of the King and Pawns, are involved in a pure mate, then it is a model mate; if all units of both colors are involved in a pure mate, then it is an ideal mate.
