Abstract

A method and apparatus are provided for at least partially disinfecting biological fluid of a mammal, which comprises pathogens in addition to normal cellular fractions. The method includes placing the biological fluid in a reaction volume and contacting a non-thermal plasma with the biological fluid to thereby kill at least a portion of the pathogens within the biological fluid.
