A blunt needle connector described herein is used for transferring fluids or medication through compatible injection ports associated with primary, secondary and central lines during intravenous therapy applications. The needle connector provides needle stick protection without recessing the needle in the shield. This feature allows the end-user to better align the injection port to the needle connector and lock the needle to the injection port to eliminate line disconnects. The blunt needle connector also provides for an audible or tactile indication that the latch is secured to the intravenous fitting. This feature makes it easy to distinguish between the open or unlocked and closed or locked position of the latch. In addition, the blunt needle connector provides attachment to an intravenous line without the twisting of the line that is associated with a threaded connector.

Blunt needle connector

A safety needle assembly for an intravenous fitting which protects against inadvertent touch contact with a piercing element after use. The assembly includes a piercing element such as a sharpened needle cannula or a blunt ended cannula that is mounted within a carrier member. A protective shield component is provided which is axially slidable relative to the carrier member and configured to attach to an intravenous fitting. The protective shield and carrier member may feature a guide assembly for guiding the shield between a pre-use, injection position and a post-use, locked position wherein inadvertent touch contact with the distal end of the piercing element is avoided. A releasable locking assembly may also be incorporated to releasably retain the protective shield in its pre-use position so as to facilitate attachment of the safety needle assembly with the intravenous fitting.

Safety needle assembly having telescoping shield

A safety needle assembly for providing secure connection of a needle cannula to a straight-site or Y-site of an intravenous fitting. The assembly includes a base portion and a protective shield disposed about the needle cannula to at least partially envelop the needle cannula within the shield. A latch is pivoted to the shield so as to releasably lock the intravenous fitting within the shield. The latch includes a pivot arm having at least one shield engaging finger member disposed to biasingly engage at least a portion of the shield, and at least one member disposed through a passageway formed in the shield to trap the intravenous fitting within the shield.

Locking safety needle assembly

A safety needle assembly is provided for locking a hypodermic syringe to a fitting of an intravenous set. The assembly includes a shield with a needle cannula mounted therein. A latch is pivotably mounted to the needle shield for rotation about an axis extending generally orthogonal to the needle cannula. The latch includes a locking flange having a slot for engagement with the fitting of the intravenous set. The latch can be lockingly engaged into a position for securely retaining the safety needle assembly to the fitting, and includes a resiliently deflectable finger for urging the latch into a fully opened condition in response to disengagement of the lock.
