Abstract
Abstract An arrangement of needle shield (10) is provided which may be attached to the hub (16) of a syringe or multiple blood sample holder (12), which shield (10) is flexible and moves out of the way of the needle point (48) for insertion into the skin, and which moves automatically over the contaminated needle (36) at the instant the needle (36) is removed from the skin for shielding the user from accidental needle stick. The arrangement is in one piece and includes an elongated hood-like body (18) which surrounds the needle (36), and includes at one end a blunt front end shield (20), and at the other end a mounting ring (17) for frictionally engaging the hub (16) of a needle holder (12) or syringe. The body (18) includes an integral lock (38) which snaps over the needle (36) for holding the shield body (18) of the invention over the contaminated needle (36).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
159 words
A needle shield for protecting a user from accidental needle stick, characterized by (a) an elongated flexible body for extending along a needle to be protected; (b) a flexible mounting grip integral with said flexible body; (c) said flexible mounting grip depending from one end of said flexible body for frictionally receiving a needle hub therein; (d) a flared needle point hood integral with said flexible body; (e) said hood depending from the end of said body opposite said flexible grip for shielding the point for shielding the point of a needle extending from a needle hub upon which said flexible ring is mounted; (f) said flexible body maintaining said hood constantly over the point of a needle extending from a needle hub upon which said flexible grip is mounted except when urged out of the way when the needle is used; and (g) said hood moving automatically over the needle point when not urged out of the way.
Claim 2
Dependent Claim
159 words
A needle shield for protecting a user from accidental needle stick, characterized by (a) an elongated flexible body for extending along a needle to be protected; (b) a flexible mounting grip integral with said flexible body; (c) said flexible mounting grip depending from one end of said flexible body for frictionally receiving a needle hub therein; (d) a flared needle point hood integral with said flexible body; (e) said hood depending from the end of said body opposite said flexible grip for shielding the point for shielding the point of a needle extending from a needle hub upon which said flexible ring is mounted; (f) said flexible body maintaining said hood constantly over the point of a needle extending from a needle hub upon which said flexible grip is mounted except when urged out of the way when the needle is used; and (g) said hood moving automatically over the needle point when not urged out of the way.
Claim 3
Dependent Claim
49 words
The needle shield of claim 1, further characterized by (a) said elongated flexible body having an elongated opening extending along the length thereof from said flexible mounting grip to said flared hood; and (b) said elongated opening allowing observation of a needle upon which said needle guard is mounted.
Claim 4
Dependent Claim
90 words
The needle shield of claim 1, further characterized by (a) an integral needle locking guard depending from said elongated flexible body; (b) said needle locking guard positioned at a point along said elongated flexible body spaced from said hood and said mounting grip; and (c) said needle locking guard for holding said elongated flexible body against a needle upon which said needle shield is mounted for maintaining said hood over the point of a needle upon which said needle shield is mounted once the hood moves automatically over the needle.
