Abstract
In some arrangements, a medical needle shield apparatus can include a binding member disposed within a shield. The binding member can include a retainer that can engaged a medical needle to prevent inclination of the binding member, and can include one or more drag inducing members that can engage the needle. In some arrangements, the apparatus can include a hub retainer.
Claims52
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 comprising binding surfaces that define an aperture configured for slidable receipt of the needle between the retracted position and the extended position,
- the binding member including a retainer extending therefrom such that the retainer is engageable with the needle to prevent inclination of the binding member while the retainer is engaged with the needle;
- the binding member further comprising 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 inclination of the binding member relative to a longitudinal axis of the needle once the retainer extends beyond the distal end 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
- a hub retainer being configured to engage a catheter hub.

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 comprising retainer means for preventing inclination of the binding member;
- the binding member further comprising drag inducing means for facilitating inclination of the binding member relative to a longitudinal axis of the needle by frictional drag forces between the drag inducing means and needle once the retainer extends beyond the distal end of the needle, and binding surface means for engaging the needle to prevent slidable movement of the needle in the extended position of the shield;
- and
- hub retainer means for releasably engaging a catheter hub.

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;
- a hub retainer being configured to engage a catheter hub;
- a binding member disposed within the shield and comprising binding surfaces that define an aperture configured for slidable receipt of the needle between the retracted position and the extended position,
- the binding member including a retainer extending therefrom such that the retainer is engageable with the needle to prevent inclination of the binding member while the retainer is engaged with the needle;
- and
- the binding member further comprising 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 inclination of the binding member relative to a longitudinal axis of the needle once the retainer extends beyond the distal end 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.
4 more elements
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;
- means for binding the shield to the needle in the extended position by enabling the binding means to incline relative to a longitudinal axis of the needle to lock against the needle and for permitting engagement with the needle to prevent inclination and to sense the end of the needle until the shield is in the extended position, wherein the binding means is disposed in the shield;
- and
- wherein the binding means further comprises a hub retainer means for releasably engaging a catheter hub such that upon activation of the binding means the hub retainer means moves to release the catheter hub from the shield so that the catheter hub and shield can be separated.
1 more element
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 hub retainer being configured to engage a catheter hub,
- the shield further including a control surface for engaging an outer surface of the catheter hub for guiding and supporting extension of the catheter hub therefrom;
- a binding member disposed within the shield and comprising binding surfaces that define an aperture configured for slidable receipt of the needle between the retracted position and the extended position,
- the binding member comprising a retainer extending therefrom such that the retainer is engageable with the needle to prevent inclination of the binding member while the retainer is engaged with the needle, and
- the binding member further comprising 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 inclination of the binding member relative to a longitudinal axis of the needle once the retainer extends beyond the distal end 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.
