Abstract
A fluid feeding device utilizes one or more fluid driving devices to cause pressure changes in an outer container of one or more fluid transfer units to change the pressure in a fluid delivery inner container within the outer container in order to expel or intake a transmitted fluid from or into the inner container, exempting the fluid feeding device from directly contacting the transmitted fluid.
