International Classification:

A61M 25/06
A61M 5/32
A61M 25/00
A61M 39/06

Abstract:

A self-slitting open lumen cannula may be used with catheter adapters to reduce manufacturing complexity and costs, as well as improve the safety of the catheter adapters against fluid leakage. The open lumen cannula may also include one or more notches to facilitate flashback visualization. The catheter adapters may further include a catheter adapter body formed of a compliant material that houses one or more compression resistant septa with at least one lumen formed by the proximal end of the needle during a self-slitting process as the catheter adapter is assembled. The compression resistant septum may also be coupled to a compression cap that imparts a radial compression force on the one or more compression resistant septa such that the at least one lumen narrows and seals when the cannula is removed.

International Classification:

A61M 25/06
A61M 25/00

Abstract:

A catheter system may include a catheter hub, a septum disposed within the catheter hub, a catheter tube extending from the catheter hub, a needle hub, and an introducer needle secured within the needle hub. The catheter hub may include a push tab and one or more ribs, which may extend outwardly from an upper surface of the catheter hub. The ribs may be shorter in height than the push tab and/or may be generally parallel to the push tab. The introducer needle may include a flashback notch. In response to insertion of the introducer needle into vasculature, blood may flow into the introducer needle, through the flashback notch, and into a flashback chamber disposed between the septum and the catheter tube. The flashback chamber may be disposed distal to the push tab and the ribs, which may improve visualization of the flashback chamber by a user.
