Device for after-use protection of a hypodermic needle, particularly of the butterfly type
First Claim
1. A device for after-use protection of a hypodermic needle, particularly of a butterfly type, comprising an elongated flat laminar element having, at one end and on two sides, two laminas which are mutually spaced by a longitudinal central band and are folded toward the laminar element in order to form two blind lateral guides for a sliding of butterfly wings of the needle, said blind lateral guides being slightly curved away from a surface of the laminar element and being adapted, when the needle retracts, to press a point of the needle so that said point slides against a surface of the central band of the laminar element in order to wedge into spaces that lie between raised saw-toothed teeth on said central band in order to prevent escape of the needle.

Abstract
A device for after-use protection of a hypodermic needle, particularly of the butterfly type, comprising an elongated flat laminar element having, at one end and on two sides, two laminas which are mutually spaced by a longitudinal central space and are folded toward the laminar element in order to form two blind lateral flat guides for the sliding of the butterfly wings of the needle. The blind lateral flat guides are slightly curved away from the surface of the element and are adapted, when the needle retracts, to press its point so that it slides against the surface of the central band of the element in order to wedge into spaces that lie between raised saw-toothed teeth on the band in order to prevent the escape of the needle.
