A luer access device (LAD) and a method of attaching the same are provided to create a sterile fluid-flow path. The LAD includes a female luer connector that has an internal female split septum disposed at a proximal end thereof and is coupled to an internal surface of the LAD. A male luer connector is coupled to an external surface of the female split septum. Additionally, a male split septum is disposed within a male luer tip and seals an opening of a distal end of the male luer connector. At least one aperture is disposed through a sidewall of the distal end of the male luer connector. An internal cannula is exposed out of the female luer connector to open the female split septum upon engagement with the male luer connector.

Sterile connection luer access device

The present invention describes a securement device that maintains proper placement of a percutaneous catheter and incorporates a universal fitting for the attachment of various, interchangeable, active and passive technologies. The securement device includes a unique catheter hub that enables attachment of active technology to provide diagnostic, therapeutic, and monitoring applications of physiologic, anatomic, and other clinically relevant properties or conditions. The securement device also includes a primary semi-flexible polymeric retention member (the 'base') positioned atop, or integrated with, a thin flexible adhesive pad. The adhesive pad has a first surface with an adhesive substrate and a second surface configured to receive the base. The hub is received within the base and a cap is used to secure the hub to the base.

Securement device with attachable members for use with a catheter

In one aspect, the present invention is directed to a multi-lumen catheter with self-sealing hub and an attachable extension assembly. In a preferred aspect, the present invention can allows removal of the external fluid connections of an elongated percutaneous medical article, such as a catheter or cannula. The percutaneous medical article suitably contains a distal septum that prevents fluid movement within the intraluminal space of the percutaneous medical article, when the fluid connections are removed. A single-use, disposable extension set of one or more single lumen lines with associated clamp and cap is attached for intraluminal access and removed following clinical use. Retaining the catheter transition allows the catheter to be secured using methods common to the art.
