Abstract
Abstract The container has an upper part A, a lower part B and a tubular middle piece C connecting the two parts A and B. Furthermore, there are connections 1, 2, 3, 4 for the withdrawal and transfusion of blood. After the container is filled with blood it is sealed in an air-tight manner and stored in a refrigerator at about +4 DEG C. Erythrocyte sedimentation has taken place after a few hours, so that a clamp can be placed above the buffy coat separating the erythrocytes from the plasma. The undesirable diffusion of haemoglobin and potassium from the erythrocytes into plasma is effectively prevented. If necessary, the buffy coat can be isolated with a second clamp and withdrawn with a syringe. If and when required, erythrocytes and plasma can be mixed in the container or used separately.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A container containing blood and comprising a first container element, a second container element, a conduit for connecting together the bottom of the first container element and the top of the second container element, and means for withdrawing a blood component from each of the container elements, the first and second container elements being so disposed and of such a volume that when the container is held vertically with the first container element above the second container element and the blood components have separated from one another, the first container element contains only the plasma component of the blood and the second container element contains only or mainly the erythrocyte component of the blood, and the conduit being of such a length and volume that the interface between plasma and erythrocyte is situated in the conduit or can be displaced into the conduit from the second container element, the conduit being closable to optionally seal off the blood components from one another.
Claim 2
Dependent Claim
162 words
A container containing blood and comprising a first container element, a second container element, a conduit for connecting together the bottom of the first container element and the top of the second container element, and means for withdrawing a blood component from each of the container elements, the first and second container elements being so disposed and of such a volume that when the container is held vertically with the first container element above the second container element and the blood components have separated from one another, the first container element contains only the plasma component of the blood and the second container element contains only or mainly the erythrocyte component of the blood, and the conduit being of such a length and volume that the interface between plasma and erythrocyte is situated in the conduit or can be displaced into the conduit from the second container element, the conduit being closable to optionally seal off the blood components from one another.
Claim 3
Dependent Claim
26 words
A container according to claim 1, in which the conduit is of a flexible material and hence closable by clamping together the walls of the conduit.
Claim 4
Dependent Claim
34 words
A container according to claim 2, in which the first and second container elements are of a flexible material and in which the conduit is formed integrally with the first and second container elements.
Claim 5
Dependent Claim
183 words
A container according to claim 3, in which the first and second container elements and the conduit are defined by a flattened flexible tubular plastics material having a first seal across the width of the tubular plastics material defining a top of the container, a second seal inclined downwardly from one edge of the flattened tubular plastics material to a point short of the other edge of the flattened tubular plastics material and defining a downwardly inclined bottom of the first container element and an opening to the conduit from the first container element, a third seal substantially parallel to said other edge of the flattened tubular plastics material leading downwardly from said point and defining the conduit, a fourth seal inclined downwardly from the lower end of said third seal to said one edge of the flattened tubular plastics material and defining a downwardly inclined top of the second container element and an opening to the conduit from the second container element, and a fifth seal across the width of the flattened tubular plastics material and defining a bottom of the container.
Claim 6
Dependent Claim
190 words
A container according to claim 3, in which the first and second container elements and the conduit are defined by a flattened flexible tubular plastics material having a first seal across the width of the tubular plastics material and defining a top of the container, a pair of second seals inclined downwardly from opposing edges of the tubular plastics material to points towards the centre of the flattened tubular plastics material and together defining a downwardly inclined bottom of the first container element and an opening to the conduit from the first container element, a pair of third seals substantially parallel to the edges of the flattened tubular plastics material leading downwardly from said points and defining the conduit, a pair of fourth seals inclined downwardly and leading outwardly from the lower ends of said pair of third seals to the edges of the flattened tubular plastics material and together defining a downwardly inclined top of the second container element and an opening to the conduit from the second container element, and a fifth seal across the width of the flattened tubular plastics material defining a bottom of the container.

A container containing blood, substantially as herein described with reference to the accompanying drawings.
Claim 8
Dependent Claim
14 words
A container containing blood, substantially as herein described with reference to the accompanying drawings.
