Abstract
An apparatus for sampling and storing biological fluids from a human or animal subject is provided. In one embodiment of the present disclosure, the apparatus includes a main body, lancet carrier or hub, lancet, lancet trigger, capillary tube, and sample compartments for collecting and storing dried blood and other bodily fluids. The lancet hub supports a lancet and provides for moving the lancet longitudinally between a first retracted position and a second extended position. The device includes a capillary tube having an internal diameter sized to draw and retain fluid from a contacted source using capillary action. The main body of the apparatus further includes a sample compartment for holding sampling and storage materials. In at least one embodiment of the present disclosure, the sample compartment can be accessed by lifting sample compartment lid. Also included is a new “fan” or “daisy” shaped collection material format for use in collecting and preserving samples.

15. A sampling and storage device for biological fluids comprising:
-
a body comprising; two or more structural components that can at least partially be attached and detached from one another and can form an open and a closed configuration , wherein the components form one or more interior cavities when in the closed position; capillary tube contained in the interior cavity and extending from an exterior of the device to the fluid reservoir and in fluid communication with the interior cavities; one or more collection compartments formed in the interior cavity and in fluid communication with the capillary tube; one or more pieces of sampling material placed within the one or more collection compartments and in fluid communication with the capillary tube; and a desiccant within the cavities in vaporous communication with the sampling material, and suitable for drying a collected sample and maintaining low humidity in the device; and a mechanism for sealing the device from the environment after use. - View Dependent Claims (17, 21, 23, 24, 25, 26, 27, 28, 41, 43, 44)

29. A method of sampling and storing a biological fluid from a subject for testing comprising:
-
providing a single use device comprising an interior cavity containing a storage compartment, a capillary tube extending from the exterior of the device into the interior cavity, and an absorbent collection material contained in the interior cavity, all contained within a single device; contacting a biological fluid of the subject with the end of the capillary tube effective to draw the biological fluid into the interior cavity and into contact with the absorbent collection material; drying the biological fluid absorbed into the absorbent collection material; and storing the dried biological material in the device. - View Dependent Claims (35, 38, 39)
