Safety shield for medical needles
First Claim
1. A medical needle shield apparatus comprising:
- a shield being extensible from a retracted position to an extended position to enclose a distal end of a needle;
a binding member disposed within the shield and defining binding surfaces that form an aperture configured for slidable receipt of the needle between the retracted position and the extended position, the binding member including one or more drag inducing members that engage the needle during slidable receipt of the needle to create a drag force with the needle, the drag force and shield facilitating rotation of the binding member relative to a longitudinal axis of the needle such that the binding surfaces engage the needle to prevent slidable movement of the needle in the extended position of the shield, the binding member further including a retainer extending therefrom such that the retainer is engageable with the needle to prevent rotation of the binding member prior to the extended position; and
a hub retainer being configured to engage a catheter hub.

Abstract
A medical needle shield apparatus including a shield that is extensible from a retracted position to an extended position to enclose a distal end of a needle. A binding member is disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the needle between the retracted position and the extended position. The binding member includes drag inducing members disposed thereon that engage the needle during slidable receipt of the needle to create a drag force with the needle. The drag force facilitates rotation of the binding member relative to a longitudinal axis of the needle such that the binding surfaces engage the needle to prevent slidable movement of the needle in the extended position of the shield. The binding member further includes a retainer extending therefrom such that the retainer is engageable with the needle to prevent rotation of the binding member prior to the extended position. The shield further includes a hub retainer for releasable attachment to a catheter hub.

27. A medical needle shield apparatus comprising:
-
a shield being extensible from a retracted position to an extended position to enclose a distal end of a needle;
a binding member disposed within the shield and including an aperture for slidable receipt of the needle between the retracted position and the extended position, the binding member defining a drag inducing means for facilitating rotation of the binding member relative to a longitudinal axis of the needle by frictional drag forces between the drag inducing means and needle, and a binding surface means for engaging the needle to prevent slidable movement of the needle in the extended position of the shield, the binding member further including a retainer means for preventing rotation of the binding member; and
a hub retainer means for releasably engaging a catheter hub. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A medical needle shield apparatus comprising:
-
a shield being extensible from a retracted position to an extended position to enclose a distal end of a needle;
a rotatable housing that encloses the shield, the rotatable housing supporting the shield for relative rotational movement therewith; and
a hub retainer being configured to engage a catheter hub.

41. A medical needle shield apparatus as recited in claim 41, further comprising:
a binding member disposed within the shield and defining binding surfaces that form an aperture configured for slidable receipt of the needle between the retracted position and the extended position, the binding member including one or more drag inducing members that engage the needle during slidable receipt of the needle to create a drag force with the needle, the drag force and shield facilitating rotation of the binding member relative to a longitudinal axis of the needle such that the binding surfaces engage the needle to prevent slidable movement of the needle in the extended position of the shield, and the binding member further including a retainer extending therefrom such that the retainer is engageable with the needle to prevent rotation of the binding member prior to the extended position. - View Dependent Claims (42)

43. A medical needle shield apparatus comprising:
-
a shield being extensible from a retracted position to an extended position to enclose a distal end of a needle;
a locking means for locking the shield to the needle in the extended position;
an end sensing member disposed in the shield and engaging the needle for activating the locking means upon sensing the distal end of the needle; and
a hub retainer being configured to engage the end sensing member and an inner portion of a catheter hub such that upon activation of the locking means the end sensing member causes the hub retainer to release the catheter hub therefrom. - View Dependent Claims (44, 45)
