Abstract: A bubble free, self-priming IV set for use in the administration of liquids includes a coupling assembly for attaching the delivery system to a source of liquid and includes a coupling membrane for controlling the flow of liquid and air through the coupling assembly. The system also includes a drip chamber for receiving liquid through the coupling assembly, the drip chamber having a membrane for preventing air from leaving the drip chamber. A self leveling port is disposed within a wall of the drip chamber, the port being permeable to air, but impermeable to liquid. Finally, a patient conduit is in fluid communication with the drip chamber and further comprises a flow control plug disposed at the distal end of the conduit. The flow control plug is permeable to air but impermeable to liquid. Use of this system allows a clinician to attach a source of fluid to a patient without significant intervention, while the system self primes.

Abstract: An intravenous catheter device having features to aid a user in hooding the beveled portion of an introducer needle during the catheterization process. An intravenous catheter device is modified to include a biasing arm capable of advancing a portion of the catheter device to cause a beveled portion of an introducer needle to be hooded within an interior lumen of the catheter tube. The dimensions of the biasing arm and various other interacting surfaces of the catheter device are configured to achieve effective hooding of the needle tip while avoiding overhooding or underhooding inaccuracies.

Abstract: A vascular access device may include a septum and a gas permeable vent in communication with at least a portion of the septum. The vent may be capable of venting gas from an extravascular system to which the vascular access device is capable of attaching. A method of venting a medical device may include providing a vascular access device having a septum and forming part of an extravascular system, providing a gas permeable vent in communication with at least a portion of the septum, and venting gas from the extravascular system through the gas permeable vent of the device.

Abstract: A Luer access device may include a housing, a septum, and a gas permeable vent in communication with at least a portion of the housing for venting gas from an extravascular system. A method of venting a medical device may include providing a gas permeable vent within a Luer access device as part of an extravascular system and venting gas from the extravascular system through the gas permeable vent of the Luer access device.

Abstract: A bubble free, self-priming IV set for use in the administration of liquids that includes a drip chamber comprising a chamber inlet and a chamber outlet, a bubble isolation device disposed within the drip chamber that prevents air bubbles from exiting the chamber outlet, a tube having an inlet end coupled to the chamber outlet of the drip chamber and an outlet end, and an end plug that includes an air vent. The end plug may be coupled to the outlet end of the tube and is a flow restrictor so that when a liquid is moving through the tube, the velocity of the liquid flow is controlled such that the front of the liquid does not trap bubbles in the tube.

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.

Abstract: The catheter and introducer needle assembly of this invention includes a catheter adapter at its proximal end having a hollow septum disposed therein. The septum preferably is hollow to minimize drag as the introducer needle is removed therefrom. If desired a gel or lubricious material may be disposed in the cavity.
