Needle safety device with antiremoval protection
First Claim
1. Apparatus comprising:
- a base having a longitudinal axis;
a housing pivotable relative to said base having two side walls each having an edge for defining a longitudinal slot therebetween wherethrough a needle passes; and
barrier means extending from said base to prevent at least one section of the edge of each of said side walls from being exposed once said housing is pivoted relative to said base to be at a position in alignment with said longitudinal axis.

Abstract
A needle safety device has a collar and a housing pivotally connected thereto. Cooperating locking members are provided at the collar and the respective lower sections of the housing so that, once the housing is pivoted to be in alignment with the collar, the locking members would coactingly mate with each other to thereby retain the housing to the collar. To ensure that the coacting locking members could not be sabotaged by the sidewalls of the housing being deliberately forced away from the collar, barriers in the form of guard flaps or arms are provided at the collar so as to prevent those sections of the sidewall that are susceptible to being forced away from the collar from being exposed. As an added benefit, the guard flaps could be used as an anchor to provide stabilization for the use of a hypodermic needle fitted with the safety needle device of the instant invention during a subcutaneous procedure to a patient.

13. A needle protection apparatus, comprising:
-
a collar having first locking portions;
a housing pivotable relative to said collar, said housing having two side walls each having a second locking portion that coactingly mates with a corresponding one of said first locking portions when said housing is pivoted to a position along a longitudinal axis of said collar;
barrier means extending from said collar to prevent the respective edges of said side walls of said housing where said second locking portions are located from being exposed once said housing is pivoted to said position along said longitudinal axis.

20. Needle protection device, comprising:
-
a base having a longitudinal axis;
a housing pivotable relative to said base having two side walls each having an edge for defining a longitudinal slot therebetween;
locking means at said base and said housing that coact with each other to retain said housing to said base once said housing is pivoted to a position in alignment with said longitudinal axis; and
two arms each extending from said base in perpendicular relationship to the edge of a corresponding one of said side walls once said housing is pivoted to said alignment position, said arms preventing said side walls of said housing from being manipulated to sabotage the integrity of said locking means that retains said housing to said base. - View Dependent Claims (21, 22, 23, 24, 26, 27, 28, 30, 31)

25. Needle safety apparatus, comprising:
-
a collar having an upper portion and a lower portion separated by an internal circumferential groove, said upper portion being an open ring and said lower portion being a close ring; and
a housing pivotably connected to said collar at a location away from the opening of said open ring so as to enable said collar to slidably mate to a needle hub via said internal circumferential groove;
wherein said collar is non-removably fitted to said needle hub once said needle hub is mated with a luer end of a medical device.

29. Safety device, comprising:
-
a collar having a longitudinal axis and two ears extending from opposite sides of said collar orthogonal to said longitudinal axis;
a housing having two side walls for defining a longitudinal slot therebetween pivotably connected to said collar, each of said two side walls having a groove or finger that coactingly mates with a corresponding one of said ears when said housing is pivoted to a position in alignment with said longitudinal axis;
two arms each extending from said collar proximately to a corresponding one of said ears to prevent respective sections of the edges of said side walls of said housing from being exposed once said housing is pivoted to said alignment position.
