  • Publication number: 20140150911
    Abstract: An infusion adapter for connection with an infusion fluid container includes a connection portion including an anchor component for connecting to an injection port of the infusion fluid container, and a first port adapted for connection with a syringe assembly containing a medication fluid. The first port is in fluid communication with the connection portion. The anchor component is configured to securely connect the infusion adapter to the infusion fluid container to substantially prevent disconnection of the infusion adapter from the infusion fluid container once the infusion adapter is connected to the infusion fluid container.

  • Publication number: 20140046258
    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: 20130274683
    Abstract: The present invention extends generally to a vascular access device that employs a septum and septum activator designed to minimize or eliminate the possibility that fluid will flow into interstitial spaces between the septum activator and the body of the vascular access device. The septum activator can be configured with a proximal end that has an outer diameter that is at least as great as the diameter of the lumen within which the septum activator is contained.

  • Patent number: 8540677
    Abstract: A vascular access device within an external environment may include a body and a septum at least partially housed within the body, a gas chamber housed within the body and the septum, and a vent adjacent the body capable of facilitating gas transfer between the gas chamber and the external environment. A method of venting a gas chamber within a medical device includes transferring gas between the gas chamber and an external environment of the device through a vent that is adjacent the body of the device.

  • Patent number: 8512287
    Abstract: A system and method for a patch-like, self-contained substance infusion device which provides one or more substantially hidden patient needles which can be placed in fluid communication with a fluid reservoir, wherein the device can be attached to a skin surface via an adhesive contact surface and a push button activation assembly can then be used to remove an interlock, allowing a disk, or Belleville spring assembly to apply an essentially even and constant pressure to the contents of the fluid reservoir, allow the release of the patient needles into the skin surface, and establish a fluid communication path between the patient needles and the pressurized fluid reservoir contents. The push button activation assembly further allows the release of one or more improved safety mechanisms after use.

  • Patent number: 8403894
    Abstract: An improved luer lock receiving septum having a configuration which provides rapid and tight resealing and yet allows penetration of the septum by the luer tip with a low penetration force. The elongated septum includes an upper portion of enlarged diameter having a target surface, a central slit, and a central, lower septum extension projecting about the slit below the upper portion and into a housing so that following luer insertion there is provided sufficient room for both the laterally displaced extension of the septum, the luer taper, and the housing to be received into a conventional luer lock connector. The septum is further preferably configured to minimize or eliminate the negative pressure deflection normally associated with the withdrawal of the large diameter luer cannula from an enclosed fluid filled lumen or chamber, by substantially isolating the lumen or chamber from the septum material displacement resultant from luer insertion.

  • Patent number: 8377010
    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.

  • Patent number: 8377040
    Abstract: A vascular access device may form part of an extravascular system and function as an adapter including a gas permeable vent. A method of venting a medical device may include providing a vascular access device as part of an extravascular system, providing a gas permeable vent within the vascular access device, venting gas from the system through the vent, and closing the vent.

  • Patent number: 8366684
    Abstract: An apparatus to control blood flow through an intravenous catheter in accordance with the present invention may include a substantially resilient helical outer shell and an inner valve portion formed therein. The inner valve portion may be configured to open upon compressing the substantially resilient helical outer shell. In some embodiments, the inner valve portion may include mating portions that substantially align to provide fluid leakage therebetween. Compressing the substantially resilient helical outer shell by, for example, inserting a Luer device into a catheter adapter containing the substantially resilient outer shell, may cause the mating portions to misalign, thereby creating a fluid path.
