Abstract:
A sterile dual-purpose closed intermittent urinary catheter system that may be used as either a drain line or a collection bag. A catheter resides within an inner cavity of an extensible sheath and may be extracted from a forward end through a hub for insertion into the urethra. A valve at a rearward end of the sheath may be opened to permit the sheath to function as a drain line, or closed to permit the sheath to function as a collection bag. The sheath has an extended length substantially longer than the catheter length. The catheter is extracted from within the sheath and inserted into the urethra to start urine flow. The urine may be collected in the sheath with the valve closed, or drained straight into a toilet with the valve open. The hub may have a source of lubrication to wet the catheter as it passes through.

Claim (Index 1):
A method of urinary catheter collection and draining, comprising:\n extracting a dual-purpose urinary catheter system from an outer package, the system having:\n an extensible flexible outer sheath having an extended length L, an inner cavity, a forward end and a rearward end, wherein the outer sheath is formed of a thin polymer tube having sufficient flexibility so as to be constricted longitudinally with folds or pleats to a partially compressed length and is configured to extend longitudinally to the extended length L by straightening out the folds or pleats; \n a urinary catheter disposed within the inner cavity of the outer sheath, the catheter having a front end and length e that is less than the partially compressed length of the outer sheath; \n a hub at the forward end of the outer sheath defining a throughbore sized to permit extraction of the catheter front end; and \n a valve at the rearward end of the outer sheath, the valve enabling conversion from a closed position to seal the inner cavity of the outer sheath at its rearward end and an open position to permit fluid flow from the inner cavity of the outer sheath at its rearward end, such that the catheter system may function as a collection bag when the valve is closed and a drain line when the valve is open; \n extending the outer sheath longitudinally to the extended length L; extracting the catheter front end from within the outer sheath through the hub; inserting the catheter front end into a patient's urethra; advancing the catheter until urine flows therethrough into the inner cavity of the outer sheath; withdrawing the catheter front end from within the patient; and positioning the rearward end of the outer sheath over a drainage receptacle; and opening the valve to the open position to permit fluid to drain from the inner cavity into the drainage receptacle.
