Abstract
A ported catheter adapter and septum actuator having various features to prevent displacement and dislodging of the septum actuator when accessing the patient's vasculature via the inserted infusion device. In particular, the systems and methods of the present invention provide an intravenous infusion device incorporating a septum actuator with a retention tab that interacts with a retention ring that is incorporated into the valve of a side port. This interaction retains the septum actuator within the lumen of the catheter adapter, thereby allowing for subsequent access to the patient's vasculature.
Claims24
A ported catheter assembly, comprising:
- a catheter adapter having a proximal end, a distal end and a lumen extending therebetween, the catheter adapter further comprising a side port forming a pathway through a sidewall of the catheter adapter and in communication with the lumen;
- a blood control septum disposed within the lumen and dividing the lumen into a proximal chamber and a distal chamber;
- a septum actuator having an outer diameter and disposed within the proximal chamber and having a base, a tip and a body extending therebetween;
- an actuator retention tab having an outer diameter and positioned on an outer surface of the body;
- and
- a valve disposed within the lumen and forming a seal between the lumen and the pathway of the side port, the valve having a retention ring comprising an inner diameter that is greater than the outer diameter of the septum actuator and less than the outer diameter of the actuator retention tab, wherein the retention ring is positioned between the side port and the blood control septum, wherein the actuator retention tab is positioned on the outer surface of the body distally to the retention ring and at a position between the retention ring and the blood control septum such that rigidity is provided to a portion of the valve between the side port and the blood control septum and a proximal end of the valve collapses in response to fluid being injected into the side port, wherein the valve comprises a flexible tube having an outer diameter that is approximately the same size as an inner diameter of the lumen, whereby the valve is retained within the lumen by an interference fit.
