发明名称 Anti-reflux valve interconnected with a catheter
摘要 An anti-reflux valve for restricting flow in one direction through a catheter toward a collection reservoir. The valve includes a check valve positioned within a segment of the catheter. The valve includes a proximal end bonded to an inside periphery of an interior of the catheter. The valve includes a pliable side wall that reduces in diameter to a distal end having an opening that is collapsible upon itself. Fluid flow is allowed through the catheter segment having the check valve therein, with flow only permitted from the proximal end and through the distal end for release into a collection reservoir. The distal end opening collapses upon itself to negate the counter-current flow of fluid through the distal end. A plurality of check valves are aligned in series to reduce the possibility of reflux flow of fluids. A method of utilization of the anti-reflux valve is also disclosed.
