Needle cover assembly for syringes

A needle cover assembly, comprising:

• a. a hypodermic needle having a proximal end and a distal end with a tip;
• b. a hollow hub member having a proximal end, a distal end and a circumferential exterior sidewall, the proximal end connectable to a syringe, and the distal end connected to said proximal end of said hypodermic needle;
• c. a protruding flange integrally molded to said circumferential exterior sidewall of said hollow hub member at a location adjacent to said proximal end;
• d. an elongated cover member having a first half and an opposite unequal second half, each half having a proximal end and a distal end, the distal end of the first half being arc shaped, the distal end of the second half being complementary to the arc shaped distal end of the first half, to form a hollow chamber enclosing said hypodermic needle, the proximal ends of said halves hingeably attached to said exterior sidewall of said hollow hub member;
• e. said first half of said elongated cover member having a greater arc than said unequal second half of said elongated cover member such that the distal end of said first half covers the tip of said hypodermic needle when in the closed position;
• and
• f. a rotatable collar member having a top rim, a bottom rim and a circumferential sidewall with a first recess notch and an opposite second recess notch located at the top rim, the circumferential sidewall having an exterior surface and an interior surface with a locking groove located adjacent to the bottom rim for tightly engaging with said protruding flange of said hollow hub member, where the rotatable collar member is adapted securely to said circumferential exterior sidewall of said hollow hub member;
• g. whereby when rotating said rotatable collar member, said unequal halves of said elongated cover member are allowed to open into said recess notches of said rotatable collar member to expose said hypodermic needle, and when said rotatable collar member is rotated back, said unequal halves of said elongated cover member are forced back together to cover said hypodermic needle.
