11998333 · 2024-06-04 · ·

Freshly obtained blood samples are deposited into a device that contains blood sample carriers, each of the carriers is designed to hold a fixed amount of blood and allow excess blood sample to flow through and be discarded. A desiccant within the blood sample carrier aids with the drying of the blood and the discarding of the excess sample blood. The device is stored/transported within a modified atmosphere package comprised of an impermeable sealable bag and an oxygen scavenger compound for removing oxygen from the bag.

DRIED BIOLOGICAL FLUID SPOT DEVICE
20190126267 · 2019-05-02 ·

Described is a dried biological fluid spot device that is formed in a cassette-like shape for easy storage and transportation. The spot device includes a top portion having one or more openings passing therethrough and a bottom portion formed to affix with the top portion. Within the spot device is a pad holder that is formed to securely hold and suspend an absorbance pad such that the absorbance pad is positioned proximate the opening. Thus, during use, an operator can deposit a biological fluid through the opening and into the absorbance pad, where it is securely stored for transport and processing.
