Needle assemblies and related methods in which a valve opener is used to push into a valve to open one or more slits on the valve to open the valve. The needle assemblies each includes a needle hub with a needle, a catheter tube with a catheter hub and the valve and valve opener positioned in the interior cavity of the catheter hub. The valve can have a valve skirt and a nose section of the valve opener can locate therein. One or more reliefs can be provided with the valve opener so that an elbow or diagonal section on a needle guard can project from a holding space within the valve opener through the relief.

Catheter devices with valves and related methods

Needle devices having a component that provides the function of fixing a valve in a standard diameter sized catheter hub, the valve and/or the component provide or provides a proximally directed axial force for returning the valve opener from a distal position within the catheter hub to a proximal position within the catheter hub when a male Luer is disconnected from the catheter hub. Various components can be located inside a single hub body catheter hub that can restrict fluid flow, allow actuation to permit fluid flow, prevent needlestick injuries, and combinations thereof.

Catheter assemblies and related methods

Needle assemblies are generally discussed herein with particular discussions extended to needle assemblies having a tip protector with a plurality of wall surfaces for preventing contact with the needle tip from a side. Aspects of the tip protectors discussed herein include a first protector body having an arm for blocking a needle tip surrounded by a second protector body having a plurality of wall surfaces.

Needle assembly and components thereof

Infusion systems and related methods involving a catheter hub and an extension or IV administration set having a male Luer connector for fluid communication with the catheter hub. A support adaptor is provided with the extension or IV administration set and has a body with a length between first and second ends, and a body wall having a continuous wall surface in a radial direction relative to the length and which defines an exterior of the body. An internal wall of the support adaptor defines a bore with the body wall, wherein the bore has first and second openings. A tubing length is located in the bore and extends out of the second opening. The bore includes first and second bore sections. Optionally, the second bore section is angled relative to the first bore section. A support surface is located beneath the bore, elevation wise.

Infusion systems, connectors for use with catheter devices, and related methods

Needle assemblies and related methods having a needle hub with a needle, a catheter tube with a catheter hub and having the needle extending through the catheter tube in a ready to use position. A valve is positioned in an interior cavity of the catheter hub, the valve having sections that can deflect in a distal direction and sections that can deflect in a proximal direction to open a fluid flow path through the valve. The valve can be deflected by a multi-piece valve opener.

A catheter assembly including a catheter hub being connectable to a device for the infusion or withdrawal of fluids; a hollow extension tube connected at its distal end to the catheter hub, the extension tube connectable at its proximal end to a device for infusing fluid into the chamber within the catheter hub; a valve assembly disposed within the chamber of the catheter hub having a first valve member and a second valve member preventing the flow of fluid through the chamber to or from the proximal end of the catheter hub. A needle guard assembly is also provided.

Catheter assembly

A safety needle assembly having a first hub attached to a flexible tube and a second hub attached to a needle projecting through the flexible tube. A needle guard is positioned in an interior cavity of the first hub. The needle guard has a proximal wall having an opening and two arms each with an end and wherein the two ends spaced from and biased toward the needle in a ready position. In a particular example, a support is located inside the cavity of the first hub and wherein the two ends of the two arms on the needle guard rest on the support in the ready position.

Safety needle assemblies and related methods

A safety needle is disclosed having a puncture needle with a needle lumen and a ground tip; a holding device that, during use, bears on the skin of a patient and holds the puncture needle; and a safety mechanism with a protection element that has a first, opened state and a second, closed state. When the holding device is taken away from the skin and/or when the holding device is moved with respect to the defined position, the safety mechanism automatically moves the protection element from a first position, in which the tip of the needle is exposed, to a second position, in which the tip of the needle is covered as the protection element at the same time transfers automatically from the first, opened state to the second, closed state.

Dialysis needle

Method, system and device involving a needle device with a needle safety element with improved stable structure. A frame can surround the needle safety element to provide added stiffening of the needle safety element. The frame can include stays extending laterally of the needle safety element. The needle safety element with the frame can be slidably located on a needle and in a catheter hub in a ready to use position and be removable from the catheter hub in a protective position.

Safety device for a hollow medical needle

Catheter assemblies are generally discussed herein with particular discussions extended to catheter assemblies having a tip protector, a valve, a valve opener, and optionally a needle wiper. The valve opener is disposed inside a catheter hub and is configured to be pushed by an IV set luer connector to open a valve following successful catheterization to pass fluids or other solutions through the catheter. A tip protector is incorporated to block the needle tip and prevent the same from accidental needle stick. A wiper is optionally included to wipe blood deposits from the needle when the same is retracted from the catheter.

Catheter assembly and components thereof

Safety intravenous catheters (IVCs) are disclosed herein having a catheter hub with a catheter tube, a needle with a needle hub, and a needle guard. The needle guard is configured to be positioned at least partially within an interior space of the catheter hub and is retained thereto by mechanical engagement between the two. Following removal of the needle from the catheter hub, the needle guard is configured to disengage from the catheter hub and attach over a tip of the needle to shield the needle tip from inadvertent needlesticks. The needle guard having an angled end section configured with a length and a width to retain the needle tip within a tip holding space behind the angled end section.

Needle safety device and assembly

Aspects of the present disclosure include needle devices in which a needle has a notch or slot. A flashback indicator is provided at least in part in the needle lumen at the notch, adjacent the notch, or partially inside and partially outside of the notch. In use, blood flow through the needle lumen is indicated at the flashback indicator. When used with a catheter tube, the flashback indicator can be viewed through the catheter tube. The needle with the notch and flashback indicator may be used with a variety of needle applications, including as catheter assemblies, indwelling assemblies, and most, if not all, over-the-needle type devices.
