Abstract
Abstract The device comprises a system of blood-taking and decanting pockets interconnected by tubes, a storage pocket, the dimensions of which correspond to the amount of component to be injected, a filter and injection means in this storage pocket. The device is particularly useful for separating by cryo-precipitation and for injecting into a patient the factor VIII used against haemophilia.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
In an apparatus for sampling and fractionating blood components including a plurality of sampling and fractionating pockets interconnected by tubing, a means for sequentially isolating, storing and intravenously injecting into a patient a blood component present in small amounts in the blood and liable to contain agglomerated elements, said means comprising: a distinct storage pocket for said component, the inlet of said storage pocket being connected by sectionable tubing to said plurality of sampling and fractionating pockets, the outlet of said storage pocket being sealed and having means for being equipped with injection means; a filter means for preventing the injection of the agglomerated elements incorporated inside said storage pocket between said inlet and said outlet; said storage pocket being of dimensions substantially corresponding to the quantity of the component separated.
Claim 2
Dependent Claim

Claim 5
Dependent Claim
68 words
An apparatus according to claim 1, wherin said filter means consists of a tubular length of a filter fabric in the form of a sleeve running longitudinally inside said storage pocket, one end of said sleeve being held closed at the bottom of said storage pocket, the other end surrounding an outlet ferrule, said other end and said ferrule being held at the top of said storage pocket.
Claim 6
Dependent Claim
92 words
An apparatus according to claim 1, wherein said storage pocket is composed of two sheets having sides welded together; said filter means consisting of a tubular length of a filter fabric in the form of a sleeve running longitudinally inside said storage pocket, one end of said sleeve being held closed between said sheets by the weld at the bottom of said storage pocket, the other end surrounding an outlet ferrule, said other end and said ferrule being held between said sheets by the weld at the top of said storage pocket.
Claim 7
Dependent Claim
16 words
An apparatus according to claim 2, wherein said injection means is integral with said outlet ferrule.
