Abstract:
1. A catheter assembly comprising: a catheter adapter having a proximal end, a distal end, and a lumen extending between the proximal end and the distal end, the catheter adapter further comprising an inner surface; a port disposed in the catheter adapter, an interior of the port being in fluid communication with the lumen; a valve disposed within the lumen, the valve including a flexible tube having a distal end and a proximal end, an interior of the flexible tube further comprising a one-way valve dividing the lumen of the catheter adapter into a proximal lumen and a distal lumen, an outer surface of the flexible tube covering an opening between the interior of the port and the lumen of the catheter adapter; a first flow pathway through the lumen of the catheter adapter, the interior of the flexible tube, and the one-way valve in a distal direction; a second flow pathway between an outer surface of the proximal end of the flexible tube and the inner surface of the catheter adapter in a proximal direction; a fluid-tight seal interposed between an outer surface of the distal end of the flexible tube and the inner surface of the catheter adapter; and a defeatable seal interposed between the outer surface of the proximal end of the flexible tube and the inner surface of the catheter adapter, wherein the defeatable seal and the second flow pathway allow fluid flow from the port into the proximal lumen, and the one-way valve and first flow pathway allow fluid flow from the proximal lumen to the distal lumen.
