Autohemotherapy
Autohemotherapy is "the immediate intramuscular or subcutaneous reinjection of freshly drawn autologous blood".[1]
In its simplest form, there is no processing involved and no refrigeration or special equipment needed, except a sterile syringe and needle, and a tourniquet.
The basic practice, as described, should not be confused with any variations which may involve oxygenation, ozone treatment, ultraviolet light, or any type of processing that would occur intermediately.
