Abstract:
1. A medical assembly comprising a medical device from which fluid flows, and a cover for the medical device including a chamber having an upstream section and a downstream section said medical device being positioned in the u stream section so fluid escaping from the device flows first into an upstream end of the downstream section and into the downstream section, flowing towards a downstream end of the chamber, said downstream section of the chamber having at least a partially porous portion decreasing in cross-sectional area from said upstream end to the downstream end so fluid flows at an increasing velocity as said fluid exits the device and flows downstream towards the downstream end, the porous portion of the chamber has a porosity that varies in stages, and where upstream stages of the porous portion of the chamber have a greater porosity than downstream stages of the chamber.
