Hmm i dont get it if is possible to install a savior medkit into a nanohive. Or can only nanoware be installed into a nanohive? ... Sorry english aint my native language - thats why i am asking such questions.

Not the Medkit itself, but you can put the Savior's nanites into a hive, then implant a (nano)biometer and then you can hook up the remainder of the Medkit externally (or implant it in a cyberlimb).
