Self-contained sampling device for processing whole blood

Abstract

A collection device is disclosed having a tubular housing detachably receiving a valved bulb reservoir at a first end thereof, the housing having a second end for dispensing fluids. The valved bulb reservoir has a sample capillary tube attached at one end thereof. The bore of the capillary is fluidically coupled to the valved bulb reservoir. The capillary is removed from the tubular housing to collect a sample in its bore, and is then replaced into the tubular housing. The contents of the valved tubular reservoir, which can be a buffer solution, a reagent, or other analytic fluid, or a gas, are then passed through the capillary bore to expel the sample and mix therewith in the housing. The sample product can then be dispensed from the tubular housing.
