Autosanguination
From Warhammer 40k - Lexicanum
Autosanguination is a procedure performed by Adeptus Mechanicus Techpriests to exsanguinate themselves, in order to replace their blood with a more effective medium.[1]
Overview
Typically, this is topped up from a portable alembic that is carried around externally. The sanguinous medium is then used to plug holes in the body and rebuild torn flesh with remarkable efficiency.[1]
