Abstract
Integrated IV catheters can have a side port that facilities drawing blood. The side port provides separate fluid pathways for drawing blood and for injecting fluids via an extension set. The side port can be configured to allow the extension set to be primed while a blood sample is collected. In this way, the collection of a blood sample at the time of catheter insertion is facilitated.
Claims17
An integrated intravenous (IV) catheter comprising:
- a catheter adapter having a catheter that is configured to be inserted into a patient's vasculature;
- a side port having a distal end by which the side port is connected to the catheter adapter, a proximal end, and a side branch, wherein the proximal end of the side port provides a first fluid pathway for drawing blood from the patient's vasculature and the side branch of the side port provides a second fluid pathway for injecting fluids into the patient's vasculature, wherein the side port further comprises an active septum valve, wherein the active septum valve comprises an actuating member and a septum, wherein the actuating member comprises a sliding tab positioned external to the side port such that the sliding tab is accessible to a clinician for manual actuation, a septum housing positioned internal to the side port and a connecting portion that connects the sliding tab to the septum housing, wherein the septum is secured to the septum housing, wherein the active septum valve is positioned at the proximal end of the side port and includes a closed position in which the septum covers the side branch to thereby close the second fluid pathway and an open position in which the septum does not cover the side branch to thereby open the second fluid pathway, and wherein the sliding tab is configured to slide proximally relative to the side port in response to the clinician's manual actuation to thereby move the active septum valve from the closed position to the open position and to slide distally relative to the side port in response to the clinician's manual actuation to thereby move the active septum valve from the open position to the closed position;
- and
- an extension set that is connected to the side port via the side branch.

An integrated peripheral IV catheter (PIVC) comprising:
- a catheter adapter having a catheter that is configured to be inserted into a patient's vasculature;
- a side port having a distal end by which the side port is connected to the catheter adapter, a proximal end, and a side branch, wherein the proximal end of the side port provides a first fluid pathway for drawing blood from the patient's vasculature and the side branch of the side port provides a second fluid pathway for injecting fluids into the patient's vasculature, wherein the side port further comprises an active septum valve, wherein the active septum valve comprises an actuating member and a septum, wherein the actuating member comprises a sliding tab positioned external to the side port, a septum housing positioned internal to the side port and a connecting portion that connects the sliding tab to the septum housing, wherein the septum is secured to the septum housing, wherein the active septum valve is positioned at the proximal end of the side port and includes a closed position in which the septum covers the side branch to thereby close the second fluid pathway and an open position in which the septum does not cover the side branch to thereby open the second fluid pathway, and wherein the sliding tab is configured to slide proximally relative to the side port to move the active septum valve from the closed position to the open position and to slide distally relative to the side port to move the active septum valve from the open position to the closed position;
- an extension set that is connected to the side port via the side branch to thereby form an extension of the second fluid pathway when the active septum valve is in the open position;
- and
- a blood collection adapter that is connected to the proximal end of the side port, the blood collection adapter comprising a cannula that extends through the septum when the active septum valve is in the closed position to thereby form an extension of the first fluid pathway, wherein the blood collection adapter interfaces with the sliding tab to prevent the active septum valve from moving from the closed position to the open position until the blood collection adapter is removed from the proximal end of the side port.

- and
- an extension set that is connected to the side port via the side branch;
- priming the extension set while the active septum valve is in the closed position;
- while the extension set is primed, obtaining a blood sample via the first fluid pathway when the active septum valve is in the closed position;
- and
- after obtaining the blood sample, moving the active septum valve from the closed position to the open position.
