Abstract
A specimen collection container assembly including a collection tube, an interior reservoir formed within the collection tube, a gel separation substance provided within the interior reservoir, and a rigid barrier member provided within the interior reservoir. Upon collection of a specimen within the interior reservoir and centrifugation of the collection tube, the specimen is divided into two primary component parts, and the gel separation substance and the rigid barrier member migrate or are otherwise moved to a transition location between the two primary component parts so as to form a physical barrier between a first component part of the specimen and a second component part of the specimen.
Claims22
A specimen collection container assembly comprising:
- a collection tube;
- an interior reservoir formed within the collection tube;
- a gel separation substance provided within the interior reservoir;
- and
- a rigid barrier member provided within the interior reservoir,
- wherein upon collection of a specimen within the interior reservoir and centrifugation of the collection tube, the specimen is divided into two primary component parts, and the gel separation substance and the rigid barrier member migrate to a transition location between the two primary component parts so as to form a physical barrier between a first component part of the specimen and a second component part of the specimen.
A specimen collection container assembly comprising:
- a collection tube;
- an interior reservoir formed within the collection tube;
- a gel separation substance provided within the interior reservoir;
- and
- a rigid barrier member,
- wherein upon collection of a specimen within the interior reservoir and centrifugation of the collection tube, the specimen is divided into two primary component parts, the gel separation substance migrates to a transition location between the two primary component parts, and the rigid barrier member is moved to the transition location so as to form a physical barrier between a first component part of the specimen and a second component part of the specimen.
A specimen collection container assembly comprising:
- a collection tube;
- an interior reservoir formed within the collection tube;
- a gel separation substance provided within the interior reservoir;
- a fixed, rigid barrier member extending from an internal sidewall of the interior reservoir;
- and
- a spring-loaded moving floor provided in a bottom portion of the interior reservoir,
- wherein upon collection of a specimen within the interior reservoir and centrifugation of the collection tube, the specimen is divided into two primary component parts, the gel separation substance migrates to a transition location between the two primary component parts, and the spring-loaded moving floor moves downward within the interior reservoir such that the fixed, rigid barrier member is positioned at the transition location between a first component part of the specimen and a second component part of the specimen.
A specimen collection container assembly comprising:
- a collection tube;
- an interior reservoir formed within the collection tube;
- a gel separation substance provided within the interior reservoir;
- and
- a chemical tablet provided within the interior reservoir, the chemical tablet comprising a hardening agent,
- wherein upon collection of a specimen within the interior reservoir and centrifugation of the collection tube, the specimen is divided into two primary component parts, the gel separation substance migrates to a transition location between the two primary component parts, and the hardening agent within the chemical tablet activates and interacts with the gel separation substance to form a rigid barrier member at the transition location between a first component part of the specimen and a second component part of the specimen.
