A needle tip shield may include a needle passageway that may receive a needle, a tip shield interior space that may receive a needle block, and a fluid restriction member. The fluid restriction member may be configured to restrict fluid leakage into and/or out of the needle tip shield. The fluid restriction member may be selected from the group consisting of: (1) a fluid impedance member located adjacent the needle passageway that may impede fluid from entering into the needle tip shield through the needle passageway; (2) a fluid retention member that may retain fluid within the tip shield interior space; and (3) an anti-splatter member that may inhibit fluid splatter when the needle block moves from an open position to a closed position within the tip shield interior space.

Inhibiting fluid leakage and splatter in catheter devices and systems

A clip used in a catheter assembly, the clip comprising a first leg and a second leg angularly connected to the first leg, wherein the second leg includes a substantially U-shaped spade configured to engage a needle housing of the catheter assembly to secure the clip to the needle housing.

Needle capture safety interlock for catheter

A catheter assembly includes a flexible catheter (), a needle () having a sharp distal tip, the needle () disposed in the flexible catheter () and moving from a first position that exposes the needle () to a second position, an outer member () that is configured to engage and disengage a catheter hub (), an inner member () disposed in the outer member (), and a needle protection () member disposed in the inner member (), the needle protection member () enclosing at least a portion of the needle () when the needle () is in the second position.

A catheter system may include a catheter adapter and a needle shield device coupled to the catheter adapter. The needle shield device may include a needle housing and a needle assembly slideably coupled to the needle housing. The needle housing may include an elongated body and a nose portion coupled to the elongated body. The elongated body may include a distal end, a proximal end, and a slot disposed between the distal end and the proximal end of the elongated body. The needle assembly may include a needle grip and a needle hub having a protuberance coupled to the needle grip and slideably fit within the slot. To facilitate securement between the catheter adapter and the needle shield device, a flexible arm of the needle shield device may couple to the catheter adapter and/or multiple protrusions of the nose portion may contact an internal wall of the catheter adapter.

Coupling between a telescoping needle shield and a catheter adapter

A catheter assembly () comprises a catheter (), a needle () having a sharp distal tip disposed in the catheter (), a catheter hub () housing the catheter () and the needle (), the catheter hub () having a collar () including a notch (), a needle shield () connected to the catheter hub () when the needle () is in a first position, and a clip () disposed in the needle shield () that cooperates with the needle (), wherein the clip () engages the catheter hub () in the first position of the needle (), and the clip () disengages the catheter hub () via the notch () when the needle () is retracted to a second position to enclose at least a portion of the needle (). The clip () is mounted in the outer housing () of the needle shield () via a spade () having an outer wall () exposed to the outside of the needle shield (), in order to reduce the overall width of the needle shield ().

Safety IV catheter with V-clip interlock and needle tip capture

A catheter assembly including a flexible catheter, a needle having a sharp distal tip, the needle disposed in the flexible catheter and moving from a first position that exposes the needle to a second position, an outer member that is configured to engage and disengage a catheter hub, an inner member disposed in the outer member, and a needle shield for shielding at least a distal end of the needle when the needle is in the second position and the needle being disposed through the needle shield in the first position.

Catheter assembly () comprises catheter (), needle () having sharp distal tip disposed in catheter (), catheter hub () housing catheter () and needle (), catheter hub () having collar () including notch (), needle shield () connected to catheter hub () when needle () is in first position, and clip () disposed in needle shield () that cooperates with needle (), wherein clip () engages catheter hub () in first position of needle (), and clip () disengages catheter hub () via notch () when needle () is retracted to second position to enclose at least portion of needle (). Clip () is mounted in outer housing () of needle shield () via spade () having outer wall () exposed to outside of needle shield (), in order to reduce overall width of needle shield ().
