ABSTRACT:
The female urinary plug (10) of the invention includes a catheter (10) with an infection-protective cap (12) fitted on the distal end (D) of the catheter insertable into the urinary bladder through the urethra (U). The catheter (10) has a soft inflatable balloon (14) on its distal end (D) and a preinflated hard balloon (18) on its proximal end (P). Prior to insertion, the inflation of the soft balloon is prevented by the inner walls of the infection-protective cap (12). The distal end of the cap (12) has a collet-like shape and is provided with expandable petal-like tongues (36a, 36b, and 36c). Normally these resilient tongues are in a closed state. When the plug is inserted into the urethra and further movement of the cap (12) is prevented due to its contact with the patient's body in the area of the orificium of the urethra, the continuing movement of the catheter (10) releases the soft inflatable balloon (14) from the cap, whereby after penetration into the urinary bladder it is inflated by compressed air contained in the preinflated hard balloon (18) and the catheter (10). In the urinary bladder, soft inflated balloon 14 rests on the walls of the urinary bladder and holds the plug in place, until the patient deflates this balloon by opening a check valve (20) on the external part of the plug.
