Abstract
Abstract The safety device of the instant invention is equipped with a fluid absorbable material at the portion of the sheath that meets the tip portion of the needle so that, as the sheath is pivoted to a position in substantial alignment with the needle, whatever fluid that has been collected at the needle is absorbed before the needle is fixedly retained by a locking mechanism, either integrated within the needle sheath or to the base and lower portion of the needle sheath, to thereby prevent splattering or aerosolization of contaminated fluid into the environment.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
142 words
Safety device to be used with a needle, comprising: a base for mating with said needle; housing means hingedly attached to said base and pivotable to a position in substantial alignment along the longitudinal axis of said needle for substantially sheathing said needle; means fitted to said housing means for absorbing fluid collected at said needle as said housing means is pivoted to said alignment position and said needle contacts said absorbing means; and locking means integral of said housing means for fixedly retaining said needle within said housing means once said housing means is pivoted to said alignment position; wherein said absorbing means is fixedly fitted to the end portion of said housing means remote from said base, and configured to contact said needle, as said housing means is pivoted to said alignment position, before said needle contacts said locking means.
Claim 2
Dependent Claim
142 words
Safety device to be used with a needle, comprising: a base for mating with said needle; housing means hingedly attached to said base and pivotable to a position in substantial alignment along the longitudinal axis of said needle for substantially sheathing said needle; means fitted to said housing means for absorbing fluid collected at said needle as said housing means is pivoted to said alignment position and said needle contacts said absorbing means; and locking means integral of said housing means for fixedly retaining said needle within said housing means once said housing means is pivoted to said alignment position; wherein said absorbing means is fixedly fitted to the end portion of said housing means remote from said base, and configured to contact said needle, as said housing means is pivoted to said alignment position, before said needle contacts said locking means.
Claim 3
Dependent Claim
137 words
Safety device to be used with a needle, comprising: a base for mating with said needle; housing means hingedly attached to said base and pivotable to a position in substantial alignment along the longitudinal axis of said needle for substantially sheathing said needle; means fitted to said housing means for absorbing fluid collected at said needle as said housing means is pivoted to said alignment position and said needle contacts said absorbing means; and first means at said housing means cooperating with second means at said base for preventing relative movement between said housing means and said base once said housing means is pivoted to said alignment position; wherein said absorbing means is configured to contact said needle before said first and second means fully cooperate to prevent relative movement between said housing means and said base.
Claim 4
Dependent Claim
137 words
Safety device to be used with a needle, comprising: a base for mating with said needle; housing means hingedly attached to said base and pivotable to a position in substantial alignment along the longitudinal axis of said needle for substantially sheathing said needle; means fitted to said housing means for absorbing fluid collected at said needle as said housing means is pivoted to said alignment position and said needle contacts said absorbing means; and first means at said housing means cooperating with second means at said base for preventing relative movement between said housing means and said base once said housing means is pivoted to said alignment position; wherein said absorbing means is configured to contact said needle before said first and second means fully cooperate to prevent relative movement between said housing means and said base.
Claim 5
Dependent Claim
101 words
Needle sheath apparatus comprising: a base; a needle mated to said base; needle sheath flexibly connected to said base and pivotable to a position in substantial alignment along said base for housing said needle; means fitted to said sheath for absorbing fluid from said needle when it contacts said needle; and locking means integral of said sheath for fixedly retaining said needle to prevent relative movement between said sheath and said needle once said sheath is pivoted to said alignment position; wherein said absorbing means is configured to contact said needle before said sheath is fully pivoted to said alignment position.
Claim 6
Dependent Claim
101 words
Needle sheath apparatus comprising: a base; a needle mated to said base; needle sheath flexibly connected to said base and pivotable to a position in substantial alignment along said base for housing said needle; means fitted to said sheath for absorbing fluid from said needle when it contacts said needle; and locking means integral of said sheath for fixedly retaining said needle to prevent relative movement between said sheath and said needle once said sheath is pivoted to said alignment position; wherein said absorbing means is configured to contact said needle before said sheath is fully pivoted to said alignment position.
Claim 7
Dependent Claim
106 words
Needle sheath apparatus comprising: a base; a needle mated to said base; needle sheath flexibly connected to said base and pivotable to a position in substantial alignment along said base for housing said needle; means fitted to said sheath for absorbing fluid from said needle when it contacts said needle; and first means at said base cooperating with second means at said sheath for fixedly retaining said sheath to said base once said sheath is pivoted to said alignment position; wherein said absorbing means is configured to contact said needle before said first and second means fully cooperate to fixedly retain said sheath to said base.
Claim 8
Dependent Claim
106 words
Needle sheath apparatus comprising: a base; a needle mated to said base; needle sheath flexibly connected to said base and pivotable to a position in substantial alignment along said base for housing said needle; means fitted to said sheath for absorbing fluid from said needle when it contacts said needle; and first means at said base cooperating with second means at said sheath for fixedly retaining said sheath to said base once said sheath is pivoted to said alignment position; wherein said absorbing means is configured to contact said needle before said first and second means fully cooperate to fixedly retain said sheath to said base.
Claim 9
Dependent Claim
93 words
In a safety device having a base, a housing hingedly attached to said base and pivotable to a position in substantial alignment with said base, and locking means integral of said housing to fixedly retain a needle mated to said base, a method of preventing fluid formed at said needle from splashing as said housing is pivoted to said alignment position, comprising the steps of: fitting to said housing means for absorbing said fluid; and configuring said absorbing means to contact said needle before said housing is fully pivoted to said alignment position.
Claim 10
Dependent Claim
93 words
In a safety device having a base, a housing hingedly attached to said base and pivotable to a position in substantial alignment with said base, and locking means integral of said housing to fixedly retain a needle mated to said base, a method of preventing fluid formed at said needle from splashing as said housing is pivoted to said alignment position, comprising the steps of: fitting to said housing means for absorbing said fluid; and configuring said absorbing means to contact said needle before said housing is fully pivoted to said alignment position.
Claim 11
Dependent Claim
128 words
