Safety shield for medical needles

摘要

A medical needle shield apparatus (10) is provided which is slidably movable along a medical needle (16) from a proximal position where a distal end of the needle is exposed, to a distal position where the shield protects the distal end of the needle. The medical needle shield apparatus includes a binding member (18) having an aperture through which the needle passes. The binding member also has binding surfaces (22) for binding to a medical needle. The shield apparatus also includes a retainer (24) integral with the binding member and in communication with the needle for temporarily retaining the binding surfaces in a non-binding position relative to the needle. The shield apparatus also includes a positioning member (26) comprising one or more friction elements (48) disposed on the needle for positioning the binding surfaces to secure the shield to the needle when a portion of the retainer (36) in contact with the needle is advanced past the distal end of the needle.
