<p>A flow regulating device provides continuous, regulated flow of a medical fluid, as well as intermittent, manually controlled larger flows of fluid to a catheter system. Such apparatus includes a control member (10) having an inlet means (16a) adapted to be connected by tubing (11) to a source of medical fluid (12) and an outlet means (16b) adapted to be connected by tubing (13) to a catheter. A flexible conduit (22) defines at least a portion of a first passage between the inlet means (16a) and outlet means (16b) of the control member (10). Positioned in the flexible conduit (22) is valve means adapted to open when the conduit (22) is squeezed, thereby providing the larger, intermittent, manually controlled flow of fluid to the catheter system, and to automatically close when the conduit (22) is released. A second passage (25) in the control member (10) connects the inlet (16a) and outlet means (16b), and in combination with flow restriction means (23) therein, provides the continuous, regulated flow of fluid to the catheter system. </p> |
