    Abstract: A medical dressing comprises at least one light source and at least one light sensor fixedly attached to a substrate and configured to measure a reddening of a portion of skin as an early indicator of phlebitis around the wound site. A method of phlebitis detection and monitoring comprises covering a wound site with a medical dressing comprising at least one light source and at least one light sensor such that the wound site is situated between the two, and whereby reddening of the skin is monitored by analyzing light reflected off the skin.

    Abstract: Catheter assemblies may include introducer needles having a notch or similar structure that allows flashback blood to enter the annular space between a catheter tube and an introducer needle of an IV catheter. The presence of flashback blood in this annular space can provide a clinician with an early, visible indication that a needle has entered a vein. The notch, however, may create a leak path for blood to escape outside of the catheter assembly, unless contained. Disclosed herein is a notch containment that prevents the notch from providing a leak path for blood to escape outside of the catheter during or after needle withdrawal.

    Abstract: A catheter assembly includes a catheter hub (12) defining an interior cavity (24) and a catheter tube (14) extending distally thereof. A rigid actuator (16) extends proximally in the interior cavity (24) and supports a seal member (18) thereon. The seal member (18) includes a central membrane (72), a distal portion (74), and a proximal portion (76). An hourglass shaped actuator cavity (88) is formed in the distal portion (74) and receives a barbed end (50) of the actuator (16). The outer surface (71) of the seal member (18) is in partial circumferential engagement with the catheter hub (12) to define an air path (102) that allows fluid communication between areas (PI and Dl) of the interior cavity (24) distal and proximal of the seal member (18). A punch tool (160) is provided to form a tri-slit (82) in the membrane (72) of the seal member (18). The seal member (18) may be configured for multi-use and include a biasing member (204) that moves the seal member (18) to force the membrane (72) back over the actuator (16) to close the membrane (72).

    Abstract: A port is adapted to be implanted to a body with its top exposed to the environment. The port has a housing defining a chamber that has an opening at the top of the housing. An aperture having a lumen attached thereto is formed at the lower portion of the chamber. For infusion, an insert that has an internal passageway that connects a fluid inlet at its top surface and a bore at its sidewall is sealingly mated to the chamber. The bore sealingly aligns with the aperture. After infusion, the insert is removed, and a blank insert is fitted to the chamber. A band of tissue ingrowth media encircles the housing to form an aseptic barrier where the outer wall of the housing and the tissue of the body encircling the housing meet.
