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.

Apparatus of claim 1, wherein said base comprises a collar that fits about a flange extending from a needle hub, said collar having an internal circumferential groove sandwiched by an upper portion and a lower portion, said upper portion being an open ring and said lower portion being a close ring;
wherein after said collar is fitted to said needle hub via its internal circumferential groove fitting about said flange and a luer end of a medical device mated to said needle hub, said collar is non-removably mated to said needle hub.
-
8. Apparatus of claim 1, wherein said barrier comprises two arms at opposite sides of said base each preventing a corresponding sidewall of said housing from being manipulated so that said housing is prevented from being pivoted away from said base once said housing has been pivoted to said alignment position.
-
9. Apparatus of claim 1, wherein said barrier comprise arms extending from opposite sides of said base, said arms providing support to stabilize a needle extending from a needle hub fitted to said base when said needle is used subcutaneously on a patient.
-
10. Apparatus of claim 5, wherein said one locking member comprises an ear extending from said base, said apparatus further comprising two ears extending from opposite sides of said base.
-
11. Apparatus of claim 5, wherein said other locking member comprises a groove, said apparatus further comprising two grooves each integral to one of the two side walls of said housing.
-
12. Apparatus of claim 5, wherein said other locking member comprises a finger, said apparatus further comprising two fingers each integral to one of the two side walls of said housing.
-
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;
a barrier 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. - View Dependent Claims (14, 15, 16, 17, 18, 19)
a latch at said housing for fixedly retaining said needle when said housing is pivoted to said alignment position.

-
19. Apparatus of claim 13, wherein said collar fits about a flange extending from a needle hub, said collar having an internal circumferential groove sandwiched by an upper portion and a lower portion, said upper portion being an open ring and said lower portion being a close ring;
wherein after said collar is fitted to said needle hub via its internal circumferential groove fitting about said flange and a luer end of a medical device mated to said needle hub, said collar is non-removably mated to said needle hub.
-
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 mechanisms 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)
