Abstract

Abstract Apparatus for collecting a sample of liquid, such as blood, having a plurality of phases of differing densities Disclosed is an apparatus for collecting a sample in an enclosed chamber, wherein said apparatus can be used with a separating means which rotates the chamber about either a longitudinal axis of the chamber, or about an axis perpendicular to the longitudinal axis of the chamber and not passing through the chamber. In addition, said apparatus facilitates automated manipulation of the sample by providing formed features for: decreasing the gas permeability of said apparatus; clot activation of a blood sample contained within said apparatus; interconnection of a multiplicity of said apparatus; automated manipulation of said apparatus; protecting markings upon said apparatus; layering the construction of said apparatus; and, encoding of information upon said apparatus in both a tactile and visual manner. Also disclosed is an apparatus for dispensing fluid from said enclosed chamber.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 42 words
Collection apparatus, comprising: a tubular inner layer formed of a first material; and a tubular outer layer formed of a second material that has different physical properties than the first material, the outer layer attached to and substantially covering the inner layer.
Claim 2
Dependent Claim 42 words
Collection apparatus, comprising: a tubular inner layer formed of a first material; and a tubular outer layer formed of a second material that has different physical properties than the first material, the outer layer attached to and substantially covering the inner layer.
Claim 3
Dependent Claim 15 words
The apparatus of claim 1 wherein the second material is less permeable than the first.
Claim 4
Dependent Claim 19 words
The apparatus of claim 1 further including label means positioned between the inner and outer layer for carrying indicia.
Claim 5
Dependent Claim 47 words
A collection apparatus, comprising: a tube having a closed end and an open end; and a closure disposed between the open end and the closed end, the closure being configured to prevent fluid flow into the space between the closure and the closed end of the tube.
Claim 6
Dependent Claim 47 words
A collection apparatus, comprising: a tube having a closed end and an open end; and a closure disposed between the open end and the closed end, the closure being configured to prevent fluid flow into the space between the closure and the closed end of the tube.
Claim 7
Dependent Claim 19 words
Apparatus for manipulating a fluid-collection tube, comprising a collar attachable to a tube to extend outwardly from the tube.
Claim 8
Dependent Claim 19 words
Apparatus for manipulating a fluid-collection tube, comprising a collar attachable to a tube to extend outwardly from the tube.
Claim 9
Dependent Claim 26 words
The apparatus of claim 5 wherein the collar includes mating means for attaching one collar to another collar to thereby secure at least two tubes together.
Claim 10
Dependent Claim 25 words
A blood collection container having an interior surface, a portion of the interior surface being roughened to facilitate coagulation of blood collected in the chamber.
Claim 11
Dependent Claim 25 words
A blood collection container having an interior surface, a portion of the interior surface being roughened to facilitate coagulation of blood collected in the chamber.
