I've read that few days ago. My suggestions are not in that topic, not closely.

Can you tell me step by step how to restore my blood with blood bags? I had a teammate that gave me his blood in the blood bag and he had the same blood type as me. After that i didnt know how to attach that blood bag to my body. Also i attached tube with needle in the end to that blood bag (i forgot the name of that item) Thank you.

That doesn't sound logic. I mean it should work both ways as long as you are not unconscious.
