Abstract
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.
Claims10
A method, comprising:
- pressing a button of an intravenous catheter assembly a first time, wherein the intravenous catheter assembly comprises:
- a catheter adapter having a sidewall extending between a distal end of the catheter adapter and a proximal end of the catheter adapter, wherein the catheter adapter further comprises an inner lumen extending within the sidewall between the distal end and the proximal end;
- an intravenous catheter coupled to the distal end of the catheter adapter, the intravenous catheter having an inner lumen in fluid communication with the inner lumen of the catheter adapter;
- a port disposed on the sidewall of the catheter adapter, the port forming an opening between the inner lumen and an external environment such that the port provides direct access to the inner lumen of the catheter adapter;
- a septum positioned within the inner lumen of the catheter adapter;
- a septum activator positioned within the inner lumen of the catheter adapter, the septum activator configured to be forced through the septum to open a fluid pathway through the inner lumen;
- and
- the button that extends through the port, wherein when the button is pressed the first time the septum activator is forced through the septum, wherein the button is configured to be pressed inwardly towards the inner lumen of the catheter adapter.
