Universal passive protector for an IV catheter
First Claim
1. A universal passive protector for an IV catheter, comprising:
- a hypodermic needle;
an over-the-needle catheter, including a hub, disposed about the needle;
a hub trap comprising first and second arms and a locking structure;
an elongate sheath; and
a slider connected to a proximal end of the needle, the slider being movable along the sheath from a distal position to a proximal position;
wherein when the slider is in the distal position, the needle extends through and cooperates with the locking structure of the hub trap so as to retain the first and second arms in a closed position wherein the hub is trapped between the first and second arms; and
when the slider is in the proximal position, a distal tip of the needle is proximal of the locking structure and the first and second arms are in an open position wherein the hub is released from the hub trap.

Abstract
A universal passive protector for an IV catheter is provided. The protector comprises an over-the-needle catheter including a proximal hub. The hub is secured within a hub trap comprising first and second interlocking arms. The hub trap is secured to a distal end of a tubular sheath. A slider is disposed about the sheath, and connected to a proximal end of the needle through a slit in the sheath. When the slider is in a distal position, the needle maintains the arms in a closed configuration wherein the hub is secured to the hub trap. When the slider is moved to a proximal position, the needle moves to a proximal position wherein the needle no longer maintains the arms in a closed position. The arms snap to an open position, releasing the hub and trapping the sharp distal tip of the needle within the sheath. Medical technicians are thus protected against accidental needle sticks.

12. A universal passive protector for an IV catheter, comprising:
-
a hypodermic needle;
an over-the-needle catheter, including a hub, disposed about the needle;
an elongate sheath;
a hub trap comprising first and second arms and a locking structure, the first and second arms being connected to a first end of the sheath, the first and second arms being selectively engageable with the hub; and
a slider connected to a proximal end of the needle, the slider being disposed about the sheath and movable therealong from a distal position to a proximal position;
whereinwhen the slider is in the distal position, the needle extends through and cooperates with the locking structure of the hub trap so as to retain the first and second arms in a closed position wherein the hub is trapped between the first and second arms; and
when the slider is in the proximal position, a distal tip of the needle is proximal of the locking structure, the first and second arms are in an open position wherein the hub is released from the hub trap, and the needle is disposed entirely within the sheath. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
