Abstract
Abstract A sleeve cover for an injection needle assembly or I.V. catheter assembly is slidably engaged to a hub and urged toward its protective position by a spring. A longitudinal groove in a side wall of the sleeve cover guides a pin protruding radially from the hub between protective and unprotective positions. When the sleeve cover is shifted rearwardly by the spring, the needle is exposed, and the sleeve is held by a locking mechanism projecting from the hub. When the locking mechanism is released, the cover shifts to its protective position. The needle assembly or I.V. catheter assembly may then be safely resealed for disposal.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
An I.V.-catheter assembly having a reservoir portion, a protruding needle affixed to the reservoir portion, and means for filling the reservoir portion through the needle, the I.V.-catheter assembly comprising: a hub having a non-circular cross-section defined about the needle proximate the conjunction of the needle with the reservoir portion, said hub having a cross-sectional area larger than the reservoir portion; a sleeve cover having a non-circular cross-section slidably engaged to said hub and selectively movable between a first position and a second position, said sleeve cover being arranged to extend over said needle when in said first position and to expose said needle and extend over said reservoir portion when in said second position; means for urging said sleeve cover towards said first position, said means for urging secured at one end by said hub and at its opposite end by an annular lip at the base of said needle; means for releasably locking said sleeve cover in said second position; and means for releasing said sleeve cover from said second position to allow return of said sleeve cover to said first position.

An I.V.-catheter assembly having a reservoir portion, a protruding needle affixed to the reservoir portion, and means for filling the reservoir portion through the needle, the I.V.-catheter assembly comprising: a hub having a non-circular cross-section defined about the needle proximate the conjunction of the needle with the reservoir portion, said hub having a cross-sectional area larger than the reservoir portion; a sleeve cover having a non-circular cross-section slidably engaged to said hub and selectively movable between a first position and a second position, said sleeve cover being arranged to extend over said needle when in said first position and to expose said needle and extend over said reservoir portion when in said second position; means for urging said sleeve cover towards said first position, said means for urging secured at one end by said hub and at its opposite end by an annular lip at the base of said needle; means for releasably locking said sleeve cover in said second position; and means for releasing said sleeve cover from said second position to allow return of said sleeve cover to said first position.
Claim 3
Dependent Claim
62 words
The I.V.-catheter assembly of claim 1 wherein said means for releasably locking said sleeve cover comprises a longitudinal groove defined in said sleeve cover, and a pin positioned to protrude from said hub and to engage said groove, said groove further comprising a transverse leg at one end to secure said sleeve cover position relative to said hub in said first position.
Claim 4
Dependent Claim
22 words
The I.V.-catheter assembly of claim 1 wherein said longitudinal groove further comprises an opening at an opposite end from said transverse leg.
Claim 5
Dependent Claim
15 words
The I.V.-catheter assembly of claim 3 wherein said opening of said longitudinal groove is pie-shaped.
Claim 6
Dependent Claim
27 words
The I.V.-catheter assembly of claim 1 wherein said hub further comprises a locking means protruding from said hub to secure said sleeve cower relative to said hub.
Claim 7
Dependent Claim
12 words
The I.V.-catheter assembly of claim 5 wherein said locking means is pie-shaped.
Claim 8
Dependent Claim
212 words
An I.V.-catheter assembly having a reservoir portion, a protruding needle affixed to the reservoir portion, and means for filling the reservoir portion through the needle, the I.V.-catheter assembly comprising: a hub defined about the needle proximate the conjunction of the needle with the reservoir portion, said hub having a cross-sectional area larger than the reservoir portion; a sleeve cover slidably engaged to said hub and selectively movable between a first position and a second position, said sleeve cover being arranged to extend over said needle when in said first position and to expose said needle and extend over said reservoir portion when in said second position; means for urging said sleeve cover towards said first position, said means for urging secured at one end by said hub and at its opposite end by an annular lip at the base of said needle; means for releasably locking said sleeve cover in said second position; and means for releasing said sleeve cover from said second position to allow return of said sleeve cover to said first position wherein said means for releasing said sleeve cover comprises fins spaced about the outer periphery of the rear portion of said sleeve cover for causing selective rotation of said sleeve cover in response to pressure applied thereto.
Claim 9
Dependent Claim
