摘要：
A catheter assembly for regulation or transfer of fluids to and from a patient. The catheter assembly may include a catheter and a valve assembly. The valve assembly may include a diaphragm having two unidirectional slit valves that open in different directions, a first unidirectional slit valve opening distally in response to an infusion-induced pressure and a second unidirectional slit valve opening proximally in response to an aspiration-induced pressure.
