  • Publication number: 20120231219
    Abstract: A device is disclosed that includes a first polymer body having tacky properties. The first polymer body has a substantially-flat exterior surface. One or more protrusions are disposed on the substantially-flat exterior surface of the first polymer body. When the one or more protrusions are in contact with a substantially-flat exterior surface of a second polymer body having tacky properties, the adhesive force between the one or more protrusions and the substantially-flat exterior surface is less than the force of gravity on the first polymer body.

  • Patent number: 8038647
    Abstract: An apparatus to automatically secure an end of a needle after contact with a blood vessel. The apparatus may include a housing and a biasing member, where the housing includes a hollow interior region extending between a proximal end and a distal end thereof. A proximal opening may be integrated into the proximal end, while a distal opening may be integrated into the distal end. The proximal and distal openings may be configured to receive a needle therethrough along a longitudinal axis. The biasing member may be coupled to the housing and configured to apply a force to the needle. The force may be oriented to displace the needle relative to the longitudinal axis upon retracting an end of the needle through the distal opening into the hollow interior region. Embodiments of the present invention may thus secure the end of the needle within the hollow interior region after use to prevent accidental needle sticks and exposure to blood and blood-borne pathogens.

  • Publication number: 20110213340
    Abstract: Infusion sets for insertion into an insertion site for preventing misalignment of the base and cap or fluid connector by providing one or more alignment features between each, and in alternative embodiments, provide one or more features to secure the cap or fluid connector to the base in anyone of a number of rotational positions and having release features to allow the cap or fluid connector to be rotatable with respect to the base portion of the infusion set, and yet easily removed and inserted. Further embodiments provide infusion sets wherein the user can easily see the insertion site of the catheter and the skin, to determine if infections have occurred at an earlier stage than was possible using prior art infusion sets and with substantially less difficulty.

  • Publication number: 20110160662
    Abstract: 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.

  • Publication number: 20110160663
    Abstract: A system for controlling fluid flow in a catheter assembly is disclosed herein. An intravenous catheter assembly has a catheter adapter and a needle hub, and the catheter adapter has an inner lumen. A septum is disposed within a portion of the inner lumen, and a slit is formed through the septum. A Parylene coating is disposed within the slit of the septum, the Parylene coating has a thickness of between approximately 0.00005 to 0.0005 millimeters. An introducer needle has a first end coupled to the needle hub and the second end extending through the inner lumen of the catheter adapter. A middle portion of the introducer needle is positioned within a portion of the septum.

  • Patent number: 7947032
    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.
