Abstract

Abstract A package for a hypodermic syringe having a relatively shiftable barrel and needle assembly for arming the syringe is provided which includes a needle sheath engageable with the needle assembly for arming the syringe when unpackaged, and a sleeve member encircling the syringe and holding the proximal end portion of the sheath radially inwardly against a portion of the syringe to prevent inadvertent arming.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 309 words
A package for a syringe and a needle assembly that are relatively movable from an unarmed condition to an armed condition comprising a generally cylindrical cover member having an open proximal end and including a main cover portion receiving the syringe and a reduced diameter open distal end portion having a smaller inner diameter than that of said main cover portion, and a sheath engageable with thE needle assembly for assisting in effecting relative axial movement between the syringe and the needle assembly to arm the same, said sheath including a main sheath portion shielding the needle assembly, and a radially outwardly flexible proximl end portion having a larger inner diameter than that of said main sheath portion and received in said main cover portion between a portion of the syringe adjacent the distal end thereof and said distal end portion of said cover member for limiting relative axial movement between the syringe and said sheath, and means connected to said cover member for closing said open end of said cover, member the inner walls of said main cover portion being disposed closely adjacent said proximal end portion of said sheath for preventing radially outward movement thereof to prevent relative axial movement between the syringe and said sheath to thereby obviate inadvertent arming of the syringe and needle assembly in the packaged condition thereof, the syringe and needle assembly and said sheath being movable together through said open end of said cover member to remove said cover member therefrom, the syringe and said sheath being relatively axially movable toward each other in response to applied forces thereon when said cover member is removed therefrom to effect flexing of said proximal end portion of said sheath radially outwardly from said syringe portion to effect relative axial movement between said syringe and needle assembly for arming the syringe and needle assembly.
Claim 2
Dependent Claim 309 words
A package for a syringe and a needle assembly that are relatively movable from an unarmed condition to an armed condition comprising a generally cylindrical cover member having an open proximal end and including a main cover portion receiving the syringe and a reduced diameter open distal end portion having a smaller inner diameter than that of said main cover portion, and a sheath engageable with thE needle assembly for assisting in effecting relative axial movement between the syringe and the needle assembly to arm the same, said sheath including a main sheath portion shielding the needle assembly, and a radially outwardly flexible proximl end portion having a larger inner diameter than that of said main sheath portion and received in said main cover portion between a portion of the syringe adjacent the distal end thereof and said distal end portion of said cover member for limiting relative axial movement between the syringe and said sheath, and means connected to said cover member for closing said open end of said cover, member the inner walls of said main cover portion being disposed closely adjacent said proximal end portion of said sheath for preventing radially outward movement thereof to prevent relative axial movement between the syringe and said sheath to thereby obviate inadvertent arming of the syringe and needle assembly in the packaged condition thereof, the syringe and needle assembly and said sheath being movable together through said open end of said cover member to remove said cover member therefrom, the syringe and said sheath being relatively axially movable toward each other in response to applied forces thereon when said cover member is removed therefrom to effect flexing of said proximal end portion of said sheath radially outwardly from said syringe portion to effect relative axial movement between said syringe and needle assembly for arming the syringe and needle assembly.
Claim 3
Dependent Claim 18 words
The package according to claim 1 wherein said cover member and said sheath are formed of plastic material.
Claim 4
Dependent Claim 36 words
The package according to claim 2 wherein said proximal end portion of said sheath is generally cylindrical and has a plurality of slots extending axially from the proximal extremity thereof defining a plurality of resilient fingers.
Claim 5
Dependent Claim 23 words
The package according to claim 1 wherein said distal end portion of each cover member defines a collar surrounding said main sheath portion.
Claim 6
Dependent Claim 36 words
The package according to claim 1 wherein in the syringe has a barrel with a radially inwardly extending distal end, and said sheath is engageable with said distal end of said barrel in the packaged conditon.
