IV Catheter Patent
 

Spring clip safety IV catheter

A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub. This in turn causes the needle guard to snap into a position in which it is clamped onto the needle shaft and in which its distal wall blocks access to the needle tip. In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.

IV catheter introducer with retractable needle

An IV catheter introducer having a retractable needle holder and a tubular plunger that are held by a detent structure in a preferred positional relationship prior to and during insertion of the catheter. Following insertion, the plunger is pushed past the detent structure, permitting a compressed spring to force the needle holder upwardly into the plunger. A vented end cap in the plunger permits rapid venting of air displaced during retraction of the needle holder. The needle holder includes a flash chamber that is easily viewable through a clear plastic housing. Wings are provided on the housing to facilitate one-handed operation of the device. A method for assembling the subject catheter introducer is also disclosed.

Safety IV catheter infusion device

A device for delivering an IV catheter to an IV infusion site is disclosed. The device includes a cylindrical housing adapted to fit into the hand of the clinician. A catheter assembly is disposed in the housing and can be advanced to an extended position and retracted. The catheter assembly includes a needle adapted to be inserted into the vein and the catheter is mounted on the needle to allow the catheter to be removed at will. The catheter assembly is rotated as the needle is inserted into the vein. Preferably the catheter assembly is rotated during the insertion of the needle and catheter. After the needle and catheter are inserted into the vein, the needle is retracted into the housing leaving the catheter in place. The housing and the needle can now be discarded.
