ABSTRACT:
A mass/heat exchange device for use as blood oxygenator, dializer, heat exchanger and the like, includes a rectangular or cylindrical elongated housing with first and second opposite axial ends. The interior of the housing is subdivided into three chambers, including an inlet chamber located at one axial end, an outlet chamber located at the opposite axial end and a central mass/heat transfer chamber located therebetween. A plurality of parallel tubes extend through the central chamber and connect the inlet and outlet chambers to provide passageways for treating medium to flow therebetween. The outer surface of each tube has the shape of a series of spherical lobes, connected end-to-end. Further, adjacent tubes are offset from one another to allow internesting of their lobes in a tight orderly packed manner. The treating medium, for example oxygen, flows through the tubes while a medium to be treated, for example blood, flows through the interstitial spaces between the tubes. The tight orderly packing of the tubes (a) reduces the priming volume, i.e. the total volume formed by the interstitial spaces to a mimimum while the outer surfaces of the tubes provide a large mass/heat exchange surface area; (b) enhances secondary flows within the main flow of the to-be-treated medium; and (c) provides even distribution of the to-be-treated medium within the exchanging chamber. The above-mentioned features make the apparatus very efficient in regard to its small priming volume.
