Passive safety Huber needle

A safety mechanism for a Huber needle assembly having a tubing and a needle extending from a distal end of the tubing, the safety mechanism comprising:

• a main body having a distal end, a proximal end, and a securement door at the distal end of the main body, the main body defining a channel to at least partially encompass the tubing, the securement door being movable between a first position to dock the main body to the needle and a second position enabling the main body to be slid away from the needle and positioned along the tubing between the needle of the Huber needle assembly and an inlet of the tubing, the main body further having a first hinge near the distal end of the main body and a first latch toward the proximal end of the main body;
• and
• a movable cover having a needle receptacle, a second hinge connected with the first hinge of the main body by a cam lock axle, and a biasing member for pivoting the movable cover about the first and second hinges relative to the main body, the movable cover further having a second latch to latch with the first latch in a closed position to retract the movable cover to engage with a bottom side of the main body, the movable cover further having a release to release latching between the first and second latches to allow the pivoting of the movable cover about the first and second hinges such that the needle receptacle of the movable cover at least partially receives the needle of the Huber needle assembly in an open position.

A passive safety Huber needle system comprising:

• a needle assembly comprising a tubing and a needle extending from a distal end of the tubing;
• and
• a safety mechanism associated with the needle assembly, the safety mechanism comprising:
• a main body having a channel at least partially encompassing the tubing and a distal end for being positioned proximate the needle of the needle assembly, the main body further having a securement door at the distal end of the main body that is movable between a first position to secure the main body proximate the needle and a second position that enables the main body to be slid away from the needle, the main body further having a first hinge near a distal end of the channel and a first latch toward a proximal end of the channel;
• and
• a movable cover having a needle receptacle, a second hinge connected with the first hinge of the main body, and a biasing member for pivoting the movable cover about the first and second hinges relative to the main body, the movable cover further having a second latch to latch with the first latch in a closed position to retract the movable cover to engage with a bottom side of the main body, the movable cover further having a release to release latching between the first and second latches to allow pivoting of the movable cover about the first and second hinges such that the needle receptacle of the movable cover at least partially receives the needle of the needle assembly in an open position.
