Abstract
The invention relates to a device useful when installed in a urinal for collection of urinary proteins. The adsorbent means includes a conduit for gravity feed passage of urine streams. The conduit has permeable layers in series containing a slow releasing antimicrobial agent and an adsorbent for urinary proteins such that for collection puropses wanted proteins are adsorbed without odor or loss due to bacterial degradation.
Claims21
A device for installation in a urinal useful for collection of urinary proteins, comprising an open ended columnar conduit for gravity feed passage of urine streams therethrough, and first and second urine stream permeable layers in the conduit, the first and second layers containing respectively (1) a leachable water soluble hydrophilic component comprising an antimicrobial agent and (2) an adsorbent for urinary proteins, the water soluble hydrophilic component including a water soluble antimicrobial that is leached ratably by exposure to intermittent urine streams and a water insoluble hydrophobic component that sublimes ratably to the air thereby gradually exposing the hydrophilic component for slow release, the respective rates of leaching and subliming during the service life being chosen such that the leaching of antimicrobial from the first layer into the second layer is sufficient to provide an inhibitor concentration effectively inhibiting microbial degradation of wanted proteins contained in the adsorbate of the second layer.
