IRMA TruPoint Capillary
Collection Device
INTENDED USE
The IRMA TruPoint Capillary Collection Device is intended for blood
collection and the transfer of whole blood samples into IRMA TruPoint
cartridges.
DESCRIPTION
Each capillary collection device contains 70 IU/mL balanced heparin and has
a fill volume of 125uL. Each device consists of a capillary tube and a plunger,
which is packaged separately. The capillary tube fills via capillary action until
the sample contacts the white plug. The upper end of the capillary tube is
sealed when blood contacts the white plug, preventing the sample from
running back out the tip of the device during handling (see Figure F-1).
Following sample collection, the plunger is inserted into the capillary tube,
and the device is attached to the IRMA TruPoint cartridge Luer port. The
sample is introduced into the cartridge by quickly and completely depressing
the plunger in one smooth motion until it stops.
