Abstract
The disclosure sets forth blood processing apparatus of the general type which employs a cylindrical rotor with a semi-permeable membrane at its outer surface, rotatable within a surrounding stationary casing or housing, blood being supplied and discharged at angularly spaced loci of the casing, a secondary fluid being supplied to the interior of the rotor, effecting a cross-transfer of a component in the blood, and a secondary fluid, or a component thereof, across the membrane, sometimes referred to as a 'journal machine' to distinguish such type from others which differ basically therefrom. The basic environment is like that of certain patents, identified hereinafter, and incorporates, by reference, features thereof insofar as they are applicable to the present disclosure. The improvements disclosed over such prior art include a membrane configuration and manner of supporting same, an openable housing construction and movable mount therefor, a secondary fluid communication connection with a hollow rotor shaft, an alternative form of housing peripheral configuration, and others to hereinafter appear. Also, as will subsequently appear, certain of the exemplary structural improvements provide novel operational differences resulting in novel blood processing, also contemplated within the purview thereof.
