Systems and methods for providing a flushable catheter assembly

摘要

A flushable catheter assembly having features to enable selective activation of fluid flow through the catheter assembly is disclosed herein. A septum is placed within the catheter adapter of the catheter assembly and includes a pathway that is closed prior to being biased open via a septum activator also positioned within the catheter adapter. A plurality of air vent channels is interposed between the septum and the inner surface of the catheter adapter to permit “flashback” of blood during insertion of the catheter into a patient. The septum activator is advanced through the pathway of the septum as a coupler is attached to a proximal opening of the catheter adapter.

主权项

1. A system for controlling fluid flow within a port of an intravenous device, comprising:
a septum disposed within an inner lumen of the port of the intravenous device, the septum dividing the inner lumen into a proximal fluid chamber and a distal fluid chamber; a septum activator having a distal tip that is positioned within the proximal fluid chamber in an un-activated position and that is forced through the septum in an activated position to thereby create a fluid path between the proximal fluid chamber and the distal fluid chamber, the septum activator being forced through the septum by a separate device when the separate device is connected to the port, the septum activator comprising a lumen through which fluid flows between the proximal fluid chamber and the distal fluid chamber, an outer wall of the septum activator including one or more openings to allow fluid to pass between the inner lumen and the lumen of the septum activator; and one or more ventilation channels formed between an outer surface of the septum and an inner surface of the inner lumen, each ventilation channel being configured to allow passage of air from the distal fluid chamber to the proximal fluid chamber while limiting or prevent flow of fluids through the ventilation channel.
