Resettable safety shield for medical needles

摘要

A medical needle shield apparatus is provided that includes a needle hub (104) having an outer needle cannula (103) extending therefrom. An inner needle (106) is disposed for slidable movement with the outer needle cannula (103). At least one shield (101) is extensible from a retracted position to an extended position to enclose a distal end of the inner needle (101). The shield (101) includes a binding member (105) disposed within the shield (101) and defines binding surfaces (122) that form an aperture (138) configured for slidable receipt of the inner needle (106). The binding member (105) includes a binding member reset surface (107) aligned with a reset surface (108) for engagement therewith to allow reuse of a shielded needle apparatus.
