The present disclosure is directed to a catheter insertion device, which has a catheter hub at the proximal end of a catheter, a tubular needle hub, at which a hollow needle is fixed and extends through the catheter hub and the catheter in a ready position such that the needle tip projects over the distal end of the catheter, a protective barrel which is received in the tubular needle hub in the ready position and is releasably connected to the catheter hub, and a pressure spring arranged between the needle hub and the protective barrel and which displaces the needle hub and the protective barrel apart from each other in an axial direction, wherein a manually operable holding member is provided between the needle hub and the protective barrel, and holds the needle hub in the ready position at the protective barrel against the bias of the pressure spring, so that after the holding member is released, the pressure spring moves the needle hub into a protective position in relation to the protective barrel, in which position the needle is positioned in the protective barrel.

IV-catheter insertion device

A needle free connector for fluid passage having a valve body with a first port; a second port; a hollow resilient membrane disposed in the valve body and having: a first end and a second end is disclosed. A flank is provided and extends between the first end and the second end fitting with the internal surface of the valve body. A slit of the first end is closed when the first end is disposed in the first port or opened when the first end is pushed into the valve body. The disclosure also proposes a drug recipient including a bottle or a bag designed to store drug and the needle free connector. The disclosure offers a needle free connector with a slitted resilient membrane having reduced priming volume.

Needle free connector with a collapsible resilient membrane fitting and corresponding method

Apparatus enables one or more needleless injection ports to be established on IV tubing as needed. An IV tubing-engaging portion secures the apparatus about the tubing. A puncturing member establishes fluid communication between the IV line and a sealing member on the apparatus. Connecting a syringe to the sealing member establishes fluid communication between the IV line and the syringe, enabling an injection to be made. When the syringe is withdrawn, the sealing member reseals to prevent fluid leakage from the IV line.

Apparatus for selectively establishing a needleless injection port on IV tubing, and associated methods

The present hinged shield assembly is configured to shield a needle to prevent needlesticks. The assembly comprises a base including a hinge, a first shield and a second shield. The first shield extends from the base and at least partially surrounds the second shield. The first and second shields are configured to pivot about the hinge. In some embodiments a distal end of the first shield is open. In other embodiments the first and second shields include sidewalls with channels extending therealong. The first and second shields are rotatable with respect to one another such that the channels in each may be aligned. In other embodiments the first and second shields are translatable and rotatable with respect to one another.

Hinged shield assembly and related methods

The various embodiments include a tubular member having an outlet. A sealing member provides a selective seal over the outlet. When the male connector is connected to a female connector, the tubular member establishes fluid communication between the connectors. In certain embodiments, fluid communication between the connectors may be interrupted even while the connectors are still connected. When the male connector is disconnected from the female connector, the sealing member reestablishes a seal over the outlet.

Selectively sealable male needleless connectors and associated methods

Syringes are disclosed herein incorporating a variety of safety mechanisms for protecting the users from accidental needle stick. In certain embodiments, the syringes incorporate retractable carriages that can be retracted into the syringe barrels by engaging with the plungers. The carriages are configured to receive different needle hubs having any number of needle sizes. In certain other embodiments, the carriages are spring loaded so that as the plungers disengage the carriages from the syringe barrels, the springs automatically retract the needles into the barrels. Still in certain other embodiments, needle hubs with spring loaded needles are used with the syringes. The needles are retracted into the barrels when the plungers activate certain mechanisms incorporated into the hubs to thereby release the needles.

Safety syringes

Protective devices for injection needles or infusion needles that include a needle holder at a proximal end of the needle, on whose shaft a protective element for the needle tip can be positioned and moved, are herein disclosed. The protective element is configured to block the needle tip following an injection to prevent accidental contact therewith. The protective element may be positioned on the shaft in a ready to use position inside a grip part or middle retaining portion, which is also used to activate the protective element over the needle following the injection.

Protective device for an injection needle

A hypodermic needle assembly configured such that the movement of a needle shield into position to block the needle tip occurs as a direct consequence of a longitudinal force applied by insertion of a syringe plunger is provided. The hypodermic needle assembly according to the present invention comprises a needle, a needle hub, and a safety spring clip assembly, the safety spring clip assembly being configured to automatically launch from the needle hub and slide along the needle until the spring clip meets a needle stop at the needle tip, thus preventing the guard from being removed from the needle shaft. A method of using the hypodermic needle assembly according to the present invention is also provided, which includes the method of launching the spring clip with a syringe having multiple advancing mechanisms.

Spring launched needle safety clip

A hypodermic needle assembly configured such that the movement of a needle shield into position to block the needle tip occurs as a direct consequence of a longitudinal force applied by insertion of a syringe plunger is provided. The hypodermic needle assembly according to the present invention includes a needle, a needle hub, and a safety spring clip assembly, the safety spring clip assembly being configured to automatically launch from the needle hub and slide along the needle to shield the needle tip, thus preventing accidental contact with the needle tip. Additional mechanisms for launching the safety spring clip are also provided, which include using a trigger ring for rotating and launching the safety spring clip. Methods for making and using the hypodermic needle assemblies are also disclosed.

A catheter introducer assembly is disclosed whereby the safety spring clip moves into position to block the needle tip occurs as a direct consequence of the withdrawal of the needle from the catheter bore. The catheter introducer assembly according to the present invention comprises a needle and a needle hub, a catheter and a catheter hub, and a safety spring clip assembly. The safety spring clip assembly being designed to permit the needle to slide inside the spring clip assembly until the needle stop located on the needle meets the proximal wall to thereby prevent further movement of the safety spring clip. A method of using the catheter introducer assembly according to the present invention is also provided.
