Abstract
A hollow filament type blood processing apparatus, typically dialyzer includes a bundle of multiple hollow filaments (3) for processing blood inserted in a housing (2). Inlet and outlet ports (12, 11) are disposed in the housing near its opposite ends for passing a dialysis fluid through the housing. The filament bundle is fixedly secured to the housing at its opposite ends by partitions (5, 6). Caps (9, 10) are fixedly attached to the opposite ends of the housing and each have a port for passing blood from one port (8) to the other port (7) through the hollow filaments. Each cap has received therein inside and outside elastomeric rings (17a, 17b). The inside elastomeric ring (17a) is interposed under pressure between the cap (9) and the partition (5). The outside elastomeric ring (17b) is interposed under pressure between the cap (9) and the housing (2). No blood leakage occurs between the caps and the housing.
