A catheter hub assembly. The catheter hub assembly includes a catheter hub body, a septum and a septum retainer, the catheter hub body having a distal end, a proximal and an internal wall defining an internal fluid passageway therebetween, the internal wall defining a transitional step within the internal fluid passageway, the septum positioned within the internal fluid passageway such that a distal end of the septum abuts up against the transitional step, the septum retainer at least partially receivable within the internal fluid passageway and having an outer wall shaped and sized to interlock with the inner wall of the catheter hub body, the outer wall including one or more lateral ribs configured to inhibit rotation of the septum retainer relative to the catheter hub body.

Closed system catheter

The present disclosure provides for a safety catheter assembly comprising a needle hub, a catheter hub, a tip protector housing. Various embodiments can comprise a push-off tab extending radially from the tip protector housing or a portion thereof, and/or structure can be added or removed to affect compliance between a catheter assembly and a catheter insertion device.

Catheter insertion device with tip protector housing

A safety intravenous catheter that includes a passive release feature. The catheter assembly includes ready, safe, and released positions. In the release position, a retainer being in a proximal retainer position relative to a collar enables release of the catheter hub from the catheter insertion device. The sharp tip of the insertion needle remains inaccessible in the release position in order to prevent unwanted needle sticks.

Safety catheter with passive release

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.

Catheter assembly with seal member

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.

Blood containment for IV catheter

A safety catheter insertion device configured to automatically retract a needle cannula following insertion of a catheter assembly and to inhibit release of the catheter assembly from the safety catheter insertion device until the needle cannula has been retracted for the purpose of inhibiting inadvertent needle sticks. The safety catheter insertion device including an advancement arm slidably coupled to a needle housing assembly and configured to shift between a first position in which a needle cannula traverses through a catheter hub coupling portion of the advancement arm to inhibit release of a catheter assembly, and a second position in which one or more tabs of the advancement arm interact with one or more retention arms of the needle housing assembly to enable a biasing mechanism to shift the needle assembly to a proximal position and enable release of the catheter assembly from the safety catheter insertion device.

Spring retract IV catheter

An intravenous catheter assembly that includes a catheter tube and an introducer needle that is disposed, at least in part, within the catheter tube when the introducer needle is in a ready for use position. The introducer needle includes a lateral surface that defines a relief that is positioned under the distal end of the catheter tube when the introducer is in the ready for use position to provide a flow path into a flash indication space.

IV catheter with vein entry indication

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.

Closed system catheter vent cap

The present disclosure provides for a safety catheter assembly comprising a needle hub, a catheter hub, a tip protector housing. Various embodiments can comprises a push-off tab extending radially from the tip protector housing or a portion thereof, and/or structure can be added or removed to affect compliance between a catheter assembly and a catheter insertion device.

A needle assembly. The needle assembly enabling the analysis of fluid trapped in a flashback chamber after an insertion needle has been inserted into a patient's vein.
