Abstract
The invention relates to an improved urinary drainage device which simulates the normal, non-catheterized urethra. This novel design significantly reduces the risk of urinary tract infection typically associated with internal catheters by providing a double-lumen drainage duct with a collapsible inner tube and an evacuator-type collection receptacle. Like the non-catheterized urethra, the inner tube collapses after urination to expel residual urine.
