Patent ID: 6984213

Claim:
A medical needle shield apparatus comprising: a first housing being configured to actuate a needle cannula disposed therewith; and a second housing being releasably engageable with the first housing, the needle cannula being disposed for slidable movement with the second housing such that the second housing is extensible from a retracted position to an extended position to enclose a distal end of the needle cannula; a binding member disposed within the second housing and comprising binding surfaces that define an aperture configured for slidable receipt of the needle cannula between the retracted position and the extended position, the binding member further comprising a retainer extending therefrom such that the retainer is engageable with the needle cannula to prevent inclination of the binding member while the retainer is engaged with the needle cannula, the binding member further comprising one or more drag inducing members that engage the needle cannula during slidable receipt of the needle cannula to create a drag force with the needle cannula, the drag force and second housing facilitating inclination of the binding member relative to a longitudinal axis of the needle cannula once the retainer extends beyond the distal end of the needle cannula such that the binding surfaces engage the needle cannula to prevent slidable movement of the needle cannula in the extended position of the second housing.
