Abstract
Abstract An elongated, unitary, blood sampling vacuum syringe, centrifuge container and specimen cup, for use with an ordinary tubular needle holder is described. The device includes an evacuated blood sample centrifuge container within one end and an evacuated specimen cup within the other end of a common tubular housing member. A transfer needle coaxially arranged within the housing member between the centrifuge container and the specimen cup effects transfer of the blood serum, after centrifuging, from the centrifuge container to the specimen cup through piercable diaphragm closure caps at the inner or facing ends thereof. Means is provided for breaking away of the specimen cup end of the common housing member for ready removal of the serum-filled specimen cup for use in analysis.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
171 words
For use with a conventional tubular blood sampling needle holder, a combination holder, centrifuge container and specimen cup comprising, in combination, an elongated tubular housing member, an evacuated tubular centrifuge container member slidably disposed within one end of said housing member and having a needle pierceable diaphragm closure cap member at each end, an evacuated specimen cup member slidably disposed in the other end of said housing member in axially spaced relation with respect to said centrifuge container member, the inner end of said specimen cup member having a needle pierceable diaphragm closure cap member, a hollow transfer needle pointed at each end, means supporting said transfer needle in longitudinal disposition within said housing member between said centrifuge container member and said specimen cup member for sequentially piercing the inner diaphragm closure cap of said centrifuge container member and the diaphragm closure cap of said specimen member upon relative axial movement, within said housing member, of said centrifuge container member and said specimen cup member with respect to said transfer needle.
Claim 2
Dependent Claim
171 words
For use with a conventional tubular blood sampling needle holder, a combination holder, centrifuge container and specimen cup comprising, in combination, an elongated tubular housing member, an evacuated tubular centrifuge container member slidably disposed within one end of said housing member and having a needle pierceable diaphragm closure cap member at each end, an evacuated specimen cup member slidably disposed in the other end of said housing member in axially spaced relation with respect to said centrifuge container member, the inner end of said specimen cup member having a needle pierceable diaphragm closure cap member, a hollow transfer needle pointed at each end, means supporting said transfer needle in longitudinal disposition within said housing member between said centrifuge container member and said specimen cup member for sequentially piercing the inner diaphragm closure cap of said centrifuge container member and the diaphragm closure cap of said specimen member upon relative axial movement, within said housing member, of said centrifuge container member and said specimen cup member with respect to said transfer needle.
Claim 3
Dependent Claim
25 words
The invention as defined in claim 1, wherein said tubular housing member, said centrifuge container member and said specimen cup member are cylindrical in shape.
Claim 4
Dependent Claim
26 words
The invention as defined in claim 1, including releasable means for constraining said centrifuge container member against inwardly sliding movement with respect to said housing member.
Claim 5
Dependent Claim
27 words
The invention as defined in claim 3, wherein said transfer needle supporting means comprises means retaining said transfer needle in fixed relative disposition within said housing member.
Claim 6
Dependent Claim
25 words
The invention as defined in claim 4, including a side-wall aperture in said transfer needle near the pointed end thereof facing said centrifuge container member.
Claim 7
Dependent Claim
35 words
The invention as defined in claim 5, including auxiliary means for venting the centrifuge container member through the inner diaphragm closure cap of said centrifuge container member upon the piercing thereof by said transfer needle.
Claim 8
Dependent Claim
59 words
The invention as defined in claim 5, wherein said housing member is provided with a peripheral weakened wall zone in the vicinity of the inner end of said specimen cup member to permit manual breakaway severing of an end portion of said housing member, for easy removal of said specimen cup member after being pierced by said transfer needle.
Claim 9
Dependent Claim
25 words
The invention as defined in claim 7, wherein said tubular housing member, said centrifuge container member and said specimen cup member are cylindrical in shape.
Claim 10
Dependent Claim
18 words
The invention as defined in claim 8, wherein said transfer needle is coaxially disposed within said housing member.
Claim 11
Dependent Claim
62 words
The invention as defined in claim 1, wherein the needle pierceable portion of said inner diaphragm closure cap member of said centrifuge container member is of lesser thickness than that portion of the diaphragm closure cap of said specimen cup and therefore offers less resistance to being pierced by said transfer needle than said diaphragm closure cap of said specimen cup member.
Claim 12
Dependent Claim
63 words
The invention as defined in claim 10, wherein the needle pierceable portion of said outer diaphragm closure cap member of said centrifuge member is of lesser thickness than that portion of the inner diaphragm closure cap of said centrifuge container and therefore offers less resistance to being pierced by said transfer needle than said inner diaphragm closure cap of said centrifuge container member.
Claim 13
Dependent Claim
37 words
The invention as defined in claim 10, wherein said tubular housing member, said centrifuge container member and said specimen cup member are cylindrical in shape, and wherein said transfer needle is coaxially disposed within said housing member.
Claim 14
Dependent Claim
35 words
The invention as defined in claim 12, including auxiliary means for venting the centrifuge container member through the inner diaphragm closure cap of said centrifuge container member upon the piercing thereof by said transfer needle.
Claim 15
Dependent Claim
25 words
The invention as defined in claim 13, including a side-wall aperture in said transfer needle near the pointed end thereof facing said centrifuge container member.
Claim 16
Dependent Claim
59 words
The invention as defined in claim 13, wherein said housing member is provided with a peripheral weakened wall zone in the vicinity of the inner end of said specimen cup member to permit manual breakaway severing of an end portion of said housing member for easy removal of said specimen cup member after being pierced by said transfer needle.
