Blood sampling control with plastic bag - utilises both blood pressure and homogenisation agitation energy

摘要

The equipment limits the amt. of blood taken for a sample to a predetermined quantity, using a plastic bag. It utilises the double action of the blood press. and the energy produced by the displacement of the internal liq. resulting from the agitation necessary for homogenisation. The system can also be used with standard glass flasks. The equipment has an omega section frame receiving the bag and the quantity limiting device is vertically adjustable on this frame to vary the bag's volume. The limiting device is an angle section piece on an arm pivoted on the frame side.
