<p>A urine tube (12) extends through a balloon (26) which is inflatable in the neck of a bladder (38) to form a seal around the urine tube (12). The balloon (26) has a shape corresponding to the shape of the bladder chamber at the urethra orifice (38) to facilitate establishing a seal. A valve (14) is provided on the outlet end (15) of the urine tube (12) and an air tube (20) extends along the substantial length of the urine tube (12) into the balloon (26). A hypodermic syringe (48) or the like may be inserted into the inlet end (22) of the air tube (20) for inflating the balloon (26). A hydrogel collar (36) is positioned around the urine tube (12) against the body (40) at the outlet end of the urethra to hold the balloon (26) in tight engagement with the bladder neck (38) at the urethra orifice.</p> |
