Distribution unit for the permeate from a reverse osmosis membrane, for the supply of purest water to a dialysis apparatus, has a secondary ring channel at the primary channel, to prevent contamination

摘要

The supply system for the delivery of the purest water to a dialysis apparatus, together with a reverse osmosis unit, has at least one secondary ring channel with its upstream section (5) concentric within the primary channel (1) to distribute the permeate from the reverse osmosis membrane. The secondary ring channel has a connection section outside the primary channel, and its downstream end (8) opens into the primary channel. The upstream section of the secondary ring channel is a straight section, from the curve (4) of the primary channel between its two straight and parallel sections (3), which can contain a throttle (10).
