An IV access device can include a needle hub that incorporates a flash chamber. The flash chamber can be used to provide visual confirmation of proper catheter placement within a vein. The flash chamber can include a path-defining structure to facilitate identifying whether blood is continually flowing into the flash chamber. The flash chamber may also be removable from the needle hub. In some cases, the needle hub may include a paddle grip that facilitates insertion of the catheter and separation of the needle hub from the catheter adapter.

Closed IV access device with paddle grip needle hub and flash chamber

A catheter system may include a catheter adapter and a wing extending outwardly from the catheter adapter. The wing may include a groove or slot. The catheter system may include a needle hub and a paddle extending outwardly from the needle hub. The paddle may include an extension disposed within the groove or the slot to reduce axial movement between the catheter adapter and the needle hub, which may be advantageous during insertion of the catheter system into a patient. The extension may be removable from the groove or the slot to allow axial movement between the catheter adapter and the needle hub during removal of the needle hub from the catheter adapter, for example. The paddle and/or the wing may include a shape to reduce axial movement between the catheter adapter and the needle hub, which may also be advantageous during insertion of the catheter system.

Providing resistance to separation of a catheter adapter and a needle hub

A blood collection system may include a needle assembly, which may include a needle configured to receive an evacuated blood collection tube. The blood collection system may include a tubing, which may include a distal end and a proximal end. The proximal end may be coupled to the needle assembly. The tubing may include a first flow channel and a second flow channel. The first flow channel may be configured to collapse at a lower pressure differential than the second flow channel.

Blood collection system with automatic pressure management and related methods

An IV catheter system may have a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a push feature protruding outwardly from the catheter hub. The IV catheter system may also have a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub, generally parallel to the axis, with a pull feature. In the insertion configuration, the needle may be positioned within the cannula and the distal end of the needle hub may be seated in a needle port of the catheter hub. In the fluid delivery configuration, the needle may be positioned outside the catheter hub. The push and pull features may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration to a fluid delivery configuration.

Ergonomic IV systems and methods

A catheter system may include a catheter adapter, a catheter extending distally from the distal end of the catheter adapter, and a needle hub coupled to the catheter adapter. The needle hub may be transparent, and a needle may be secured within the needle hub. The catheter system may also include a flow control plug coupled to the proximal end of the needle hub. In some embodiments, a flashback pathway may be disposed between an outer surface of the flow control plug and an inner surface of the needle hub. In some embodiments, the catheter system may include an inner barrel and an outer barrel, and the inner barrel and the needle hub may be configured to move proximally within the outer barrel to retract the needle. The flashback pathway may be disposed between an outer surface of the needle hub and an inner surface of the inner barrel.

Blood collection devices, systems, and methods facilitating blood flashback

A medical assembly includes an expandable-mouth catheter and an introducer tool configured to facilitate advancement of the catheter into a delivery sheath. In some examples, a distal-most portion of the introducer tool includes a plurality of axial extensions separated by triangular-shaped slits. When the catheter is received within the introducer tool and when the introducer tool is received within a tapered portion of the delivery sheath, the axial extensions are configured to collapse radially inward to radially compress the expandable member and to enable the introducer to extend farther into the delivery sheath.

Expandable-mouth catheter introducer tool

The present invention relates to peripheral intravenous catheters, and in particular to an integrated peripheral intravenous catheter having a low profile securement platform, a needle hub having an interior compartment and further comprising a paddle grip, and an extension tube coupled to the catheter and stored within the interior compartment of the needle hub prior to catheterization.

Intravenous catheter device with integrated extension tube

A storage container having a base storage compartment configured to receive a divider by which the storage compartment is divided into two or more sub-compartments, wherein divider includes a tool configured to provide a secondary utility or function unrelated to dividing the storage compartment.

Pressure-driven flow rate control valves

An IV device assembly may include a lumen forming a fluidic channel within the IV device assembly. The lumen may be fluidically coupled to a vascular access device (VAD) coupler via a funnel coupler, and an IV device assembly coupler at a proximal end of the lumen. The IV device assembly may also include one or more of the following: a collapsible sleeve formed coaxially around a first portion of the lumen and mechanically coupled to the funnel coupler, a patency instrument formed along a second portion of the lumen within the collapsible sleeve and into the VAD coupler, a translation handle that translates the patency instrument out of a distal end of the VAD coupler, and a fixed grip formed around the lumen to maintain a position of the IV device assembly relative to the translation handle.

Vascular access device assembly facilitating single-handed patency probe advancement

Catheter systems comprising independent fluid paths are disclosed. The catheter systems can include a catheter adapter that has a catheter hub with a chamber. A catheter extends from a distal end of the catheter hub and is in fluid communication with the chamber. A stabilization platform with a first wing and a soft push tab are also part of the catheter hub. The catheter system includes a needle hub with a needle that slidably fits within the catheter. In an insertion configuration, a proximal extension of the catheter hub is removably coupled within a distal opening of the needle hub. After the catheter is placed, the needle hub is retracted from the catheter adapter to slidably remove the needle from the catheter.

Integrated catheter with independent fluid paths

In some examples, a medical assembly includes a catheter and a delivery-assist tool. The catheter includes an elongated body comprising a proximal body portion and a distal body portion and defining a body inner lumen; and an expandable member located at the distal body portion, the expandable member defining an expandable member inner lumen. The delivery-assist tool includes a support structure configured to extend through the body inner lumen and the expandable member inner lumen of the catheter; and a flexible cover coupled to a distal portion of the support structure, wherein the flexible cover is configured to facilitate compression and retention of the expandable member in a delivery configuration while being advanced through a delivery sheath and while the support structure extends through the body inner lumen and the expandable member inner lumen.

Expandable-mouth catheter delivery-assist tool

A catheter system may include a catheter adapter and a catheter extending distally from the catheter adapter. The catheter system may include a needle assembly, which may include a plug, an outer housing, and an introducer needle. An outer surface of the plug may include multiple grooves, which may be in fluid communication with the introducer needle and configured to receive blood flashback. The grooves may include a first groove having a first surface-area-to-volume ratio, and a second groove having a second surface-area-to-volume ratio. The first surface-area-to-volume ratio may be less than the second surface-area-to-volume ratio. The first groove may have a greater volume than the second groove. The outer housing may seal a top of the first groove and a top of the second groove to prevent blood from flowing out the top of the first groove and the top of the second groove.

Catheter systems and methods for flashback visualization at various blood pressures

A method may include priming a catheter system. The catheter system may include a catheter adapter, a catheter, and an extension tube. The catheter system may also include a Y-adapter, which may include first and second arms. A distal end of the Y-adapter may be coupled to the extension tube. The catheter system may further include a vent cap, which may be coupled to the second arm. Priming the catheter system may include attaching an IV line to the first arm and delivering saline through the IV line to the catheter system such that the saline exits a distal tip of the catheter and clamping the IV line via a roller clamp on the IV line. The method may also include actuating the vent cap after priming the catheter system. The method may further include inserting the catheter into a vein of a patient after actuating the vent cap.

Systems and methods for catheter insertion and blood flashback

A catheter assembly may include a catheter adapter, a septum housing, and a septum. The catheter adapter may include a distal end, a proximal end, an inner wall extending between the distal end and the proximal end, and a lumen formed by the inner wall. The septum housing may include one or more protrusions and may be secured to the inner wall by one or more of the following: an interference fit between the one or more protrusions and the inner wall, a snap fit between the one or more protrusions and the inner wall, and bonding between the one or more protrusions and the inner wall. The septum may be at least partially disposed within the septum housing and configured to at least substantially seal the lumen.
