摘要：
A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator is positioned to extend proximally in the interior cavity and support a seal member positioned thereon in the interior cavity. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. The seal member may be configured for multi-use and include a biasing member that moves the seal member to force the membrane back over the actuator to close the membrane.
