ABSTRACT:
The invention relates to an improved urinary drainage device which simulates the inlet end of the normal, non-catheterized urethra. This novel design significantly reduces the risk of urinary tract infection typically associated with internal catheters by providing a drainage duct comprising a truncated, collapsible inner lumen. Like the non-catheterized urethra, the collapsible inner lumen collapses after urination to prevent urine back flow. The invention further relates to an improved evacuator-type collection receptacle, the improvement comprising a resilient means or displacement means for controlling the negative pressure created within the collection receptacle.
