Safety Shield for Medical Needles
| Content Provider | The Lens |
|---|---|
| Abstract | A medical needle shield apparatus is provided that includes a needle hub having a needle cannula extending therefrom. At least one shield is extensible from a retracted position to an extended position to enclose a distal end of the needle. The shield includes a binding member disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the inner needle. The binding member includes at least one drag inducing member that engages the inner needle during slidable receipt to create a drag force. The drag force facilitates rotation of the binding member such that the binding surfaces engage the inner needle to prevent slidable movement. The shield and/or hub includes a retention element engageable between the shield and hub and a sheath retention element. The hub includes a magnifier for viewing fluid flashback. |

| Claim | A medical needle shield apparatus, comprising: a shield configured to slide along a needle from a retracted position proximal of a distal end of the needle to an extended position at the distal end of the needle, the shield enclosing the distal end of the needle in the extended position; and a binding member disposed within the shield, comprising: an aperture plate including an aperture configured for slidable receipt of the needle between the retracted position and the extended position; a sensing member extending from the aperture plate including a needle communicating surface at a distal end thereof, and at least one drag-inducing member in contact with the aperture plate, the at least one drag-inducing member engaging the needle and creating a drag force with the needle to cause inclination of the binding member, including rotation of the entire at least one drag-inducing member in the same direction as the aperture plate, relative to a longitudinal axis of the needle once the needle communicating surface extends beyond the distal end of the needle. The medical needle shield apparatus according to claim 1 , wherein the at least one drag-inducing member is in the form of a ring. The medical needle shield apparatus according to claim 2 , wherein the at least one drag-inducing member comprises a first ring and a second ring positioned on opposing sides of the aperture plate. The medical needle shield apparatus according to claim 1 , wherein the at least one drag inducing member comprises first and second frictional members extending from the aperture plate, each of the first and second frictional members including an arm, the first frictional member arm spaced apart from the second frictional member arm such that a gap between the arms is aligned with the aperture of the aperture plate, each of the first frictional member arm and second frictional member arm engaged with the needle. The medical needle shield apparatus according to claim 1 , wherein the aperture plate is substantially perpendicular relative to the longitudinal axis of the needle in the retracted position. The medical needle shield apparatus according to claim 1 , wherein the binding member is rotatable, relative to the longitudinal axis of the needle, between a non-binding orientation in which the needle is slidable relative to the binding member and a binding orientation in which binding surfaces of the aperture plate engage the needle to prevent movement of the needle in the extended position. The medical needle shield apparatus according to claim 6 , wherein the shield comprises a housing that defines at least one blocking member extending from an interior surface thereof, the at least one blocking member being engageable with the binding member for urging the binding member to the binding orientation. The medical needle shield apparatus according to claim 7 , wherein the housing is freely rotatable with respect to the needle. The medical needle shield apparatus according to claim 1 , wherein the shield is coupled to a hub in the retracted position. The medical needle shield apparatus according to claim 9 , wherein the shield is separable from the hub in the extended position. |
