Abstract: A method of constructing a catheter assembly having an integrated septum. The method comprising molding a catheter hub having a distal end, a proximal end, and an internal wall defining an internal fluid passageway therebetween, the internal fluid wall defining an injection mold window located between the distal end and the proximal end; seating a catheter tube within the internal fluid passageway of the catheter hub, such that a proximal end of the catheter tube resides within the internal fluid passageway of the catheter hub, and a distal end of the catheter tube extends distally from the distal end of the catheter hub; plugging at least a proximal end of the catheter hub with a mold core shut off pin; and injection molding a septum in at least a portion of the internal fluid passageway between the mold core shut off pin and the proximal end of the catheter tube through the injection mold window.

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: A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator is positioned to extend proximally in the interior cavity and support a seal member positioned thereon in the interior cavity. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. The seal member may be configured for multi-use and include a biasing member that moves the seal member to force the membrane back over the actuator to close the membrane.

Abstract: A self activating vent cap configured to be operably coupled to a needleless connector and automatically shifted relative to the needleless connector from the first, storage position to a second, activated position upon rotation of the vent cap relative to the needleless connector. The self activating vent cap including a threaded portion, an activation portion and a biasing mechanism, wherein shifting of the activation portion to the second, activated position is selectively precluded by the interference of at least one ridge of the threaded portion with a ledge of the activation portion.

Abstract: An LVP that provides peristaltic pumping to removably couplable administration set tubing assemblies supplying medical infusate. The LVP includes a housing, a drive-train assembly, and a controller. The housing includes an assembly receptacle configured to receive an administration set tubing assembly. The drive-train assembly provides mechanical peristaltic movement within the assembly receptacle. The drive-train assembly includes a stepper motor located within the housing and a camshaft assembly, driven by the stepper motor and at least partially extending into the assembly receptacle. The camshaft assembly includes a unitary camshaft and a plurality of tube engaging members that cooperatively move according to rotation of the unitary camshaft. Further, the controller is located within the housing that controls operation of the stepper motor and the camshaft assembly.

Abstract: An assembly is configured to position a peristaltic tube with respect to a linear peristaltic pump drive of an infusion pump. The assembly can include a peristaltic tube, first and second tube couplers, a frame, first and second securement plates, a free-flow prevention arm, and a biasing mechanism. The frame can include a snap-fit tab configured to releasably secure the assembly to an assembly receptacle of the infusion pump. The free-flow prevention arm can be selectively movable between a free-flow preventing position and a free-flow allowing position. A latching mechanism can be ergonomically manipulable to latch the free-flow prevention arm in a free-flow allowing position, and to unlatch the free-flow prevention arm such that the biasing mechanism is able to bias the free-flow prevention arm to the free-flow preventing position.

Abstract: Infusion pumps and associated methods for delivering medicament to a user during error conditions. An infusion pump can include a sensor, a pumping mechanism to deliver medicament through an infusion set to the user, and a processor operably coupled to the sensor and the pumping mechanism. The processor can be configured to receive an indication from the sensor of an error condition, and continue operating the pumping mechanism to deliver a predetermined quantity of medicament without correcting the error condition. The predetermined quantity can be based at least in part on a characteristic of the infusion set.

Abstract: An access device for placing a medical article within a body space includes a syringe, a needle, and a sheath which are employed together with a guide wire. The sheath can be coaxially and slideably disposed about the needle. During insertion of the sheath over the needle, guide wire and into the body space, the syringe provides a negative pressure to ensure that any air located between the inside diameter of the sheath and the outside diameter of the needle is drawn into the needle rather than into the body space. In certain embodiments, a dilator is coaxially and slideably disposed about the needle and within the sheath.
