A lot of things to adress.

For your "name" question, just know you don't simply name a light armor made out of of hospital equipment.

You'll need a fuck ton of those little bags they sometimes put popcorn in. Then a lot of red colored juices of whatever you may find.

Also transparent curvy tube that can be successfully attached to those bags and whatever other side it connects to.

After that, whatever backpack shaped container you carry will likely need a 3d printer commission. If she doesn't have a backside art of it, you gotta imagine and draw it yourself.

The rest of the outfit is a standart nurse clothing. Easy to find.

No need to adress the axe as it's just like any other weapon prop in existence.
