Among other things, a flow-controlling catheter hub configured to connect with and adjust fluid flow to a catheter is shown. The hub includes a main body, a valve, and a luer fitting adapter. The main body, valve, and luer fitting adapter each have an interior passageway to receive and conduct fluid flow when the parts are assembled together. The valve is configured to engage the interior passageway of the main body to block fluid flow when the valve is in a closed position. When the valve is in an open position the valve is moved away from the interior passageway of the main body and fluid flows through the interior passageway of the main body. The luer fitting adapter freely rotates in the valve while the valve is adjusted relative to the main body. Adjustment of fluid flow to the catheter is possible without disturbing connections between parts. |
