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 having a piercable diaphragm cap and being supported in spaced relation within one end of a housing member, the opposite end of which housing member is in the form of a separable specimen cup. After obtaining a blood sample in the usual fashion with use of an ordinary tubular needle holder, the device is centrifuged as a unit to separate the blood serum into the upper end of the centrifuge container. Vertically spaced openings provided in an upper side wall portion the centrifuge container and normally sealed off by means of a pressure-sensitive tear strip, are thereafter sequentially opened by manual removal of the tear strip to permit gravitation of the centrifuged blood serum down into the specimen cup, after which said serum-filled specimen cup can be separated for use in analysis.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 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, and evacuated blood sample collecting tube, means supporting said collecting tube in spaced relation within one end of said housing member, the outer end of said collecting tube being fitted with a needle pierceable closure cap member, the other end of said housing member being closed, and normallyclosed, manually-controlled aperture means in a side-wall portion of the outer end portion of said collecting tube for draining centrifuged blood serum from said collecting tube into the closed end of said housing member and means on said housing member allowing access to said manually-controlled aperture means.
Claim 2
Dependent Claim
120 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, and evacuated blood sample collecting tube, means supporting said collecting tube in spaced relation within one end of said housing member, the outer end of said collecting tube being fitted with a needle pierceable closure cap member, the other end of said housing member being closed, and normallyclosed, manually-controlled aperture means in a side-wall portion of the outer end portion of said collecting tube for draining centrifuged blood serum from said collecting tube into the closed end of said housing member and means on said housing member allowing access to said manually-controlled aperture means.
Claim 3
Dependent Claim
53 words
The invention as defined in claim 1, wherein said other end of said housing member is in the form of a specimen cup having an open end facing the inner end of said collecting tube in longitudinally-space relation, and means for separating said specimen cup from the remainder of said tubular housing member.
Claim 4
Dependent Claim
43 words
The invention as defined in claim 2, wherein said aperture means comprises a plurality of vertically aligned openings in said collecting tube, and a pressure-sensitive tear strip normally adhered to said collecting tube in sealing relation with respect to said plurality of openings.
Claim 5
Dependent Claim
31 words
The invention as defined in claim 3, wherein said means allowing access comprises an elongated opening in said tubular housing member permitting access for manual tearing away of said tear strip.
Claim 6
Dependent Claim
22 words
The invention as defined in claim 4, wherein a lowermost sub-plurality of openings of said plurality of openings are of triangular shape.
Claim 7
Dependent Claim
21 words
The invention as defined in claim 5, wherein said tubular housing member is integrally formed of a transparent synthetic plastic material.
Claim 8
Dependent Claim
38 words
The invention as defined in claim 6, wherein said means for separating comprises a peripheral weakened wall zone at the upper end of said specimen cup to permit manual breakaway thereof after being supplied with a serum specimen.
