Catheter adapter port valve
A catheter assembly is disclosed that includes a catheter adapter having a port disposed on its sidewall. A valve is coupled to the port to seal the opening in the port.
1. A catheter assembly, comprising:
a catheter adapter having a distal end and a proximal end and an inner lumen extending between the distal end and the proximal end;
a port extending from the catheter adapter, wherein the port forms an opening between the inner lumen and an external environment; and
an iris valve disposed within the port and forming a barrier across the port, wherein a horizontal plane of the iris valve is perpendicular to a longitudinal axis of the port; and
an actuator having a longitudinal axis and extending from a wall of the port perpendicular to the port and coupled to the iris valve, the actuator comprising a gripping portion having a longitudinal axis that is coaxial with the longitudinal axis of the actuator and with the horizontal plane of the iris valve, wherein the actuator is configured such that in response to the actuator being turned, the iris valve is moved between an open position and a closed position, wherein the actuator extends through an opening in the wall of the port, wherein a longitudinal axis of the opening in the wall of the port in a cross-section of the catheter assembly intersects the longitudinal axis of the port.
2. The catheter assembly of claim 1 , wherein the catheter adapter further comprises a catheter coupled to the distal end of the catheter adapter.
3. The catheter assembly of claim 1 , wherein the catheter adapter further comprises a septum activator disposed within the inner lumen.
4. The catheter assembly of claim 1 , wherein the iris valve is spaced apart from an end of the port.
5. The catheter assembly of claim 4 , wherein the end of the port comprises a luer thread, wherein the iris valve is spaced apart from the luer thread.
