Filed:

Apr 21, 2004

Appl. No.:

10/828964

Inventors:

Weston F. Harding - Lehi UT, US

Kelly D. Christensen - Centerville UT, US

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

A61M 5/14

US Classification:

604256, 604 86, 60416701, 60416702, 60416704, 2511491, 2511493

Abstract:

A needleless luer access connector is disclosed having a septum disposed in a housing. The septum has a proximal portion with a cross section, a medial portion with a cross section smaller than the cross section of the proximal portion, and a distal portion. A longitudinal slit extends through the septum from the proximal portion to the distal portion. The septum and housing are designed so that septum will not be rotated or removed from the housing when the connector is accessed by a male luer taper. In addition, the septum and housing are designed to bias the slit at the distal portion closed and so a male luer connector does not have to extend completely through the distal portion to open the slit at the distal portion. Finally, the septum and housing are designed to minimize the amount of dead space in the connector when accessed with a male luer taper.

International Classification:

A61M 39/10

US Classification:

604533

Abstract:

A medical device includes a vascular access device with an access port having a septum and a slit. The slit is formed on the inner surface of the body of the septum where the access port receives an access device that is separate from the vascular access device through the slit of the septum. A pivoting member in communication with the access port pivots when the port is accessed by an access device. The medical device may be used to control the volume displacement of a chamber within the medical device by decreasing the volume of the chamber by inserting a substance having a mass into the chamber, pivoting a structure associated with the chamber, and increasing the volume of the chamber simultaneously and commensurately with the mass of the substance inserted into the chamber.

A61M 5/178

US Classification:

604201, 60416702

Abstract:

A vascular access device within an external environment may include a body and a septum at least partially housed within the body. Septum may at least substantially seal a lumen extending through the body. The septum may further include at least a first and a second material. At least one of the materials of the septum may be selected or adapted to resist tearing of the septum.

International Classification:

A61M 5/00

US Classification:

604246, 604247

Abstract:

A medical access device provides needleless access to patient fluid lines such as intravascular catheters. A retaining ring at the top end of the housing of the medical access device is molded around a septum that provides access for a tubular portion of a medical device such as a male luer taper of a syringe. Alternatively, the retaining ring may also be molded around the body or around both the body and the base of the housing. The molded retaining ring and septum are attached by mechanical attachment and/or chemical adhesion to minimize axial and rotational movement between the septum and the housing.
