| 摘要 |
A flow restrictor includes an exterior tube and an interior tube disposed within the exterior tube. A first flange is disposed at a distal end of the interior tube. An annular rib extends proximally from the first flange and has an interior diameter greater than an exterior diameter of the exterior tube. A second flange is disposed at a proximal end of the exterior tube. A ring member is disposed around the exterior tube between the annular rib of the first flange and the second flange. |
