Abstract
A portable hand-held blood sampling device having a self-filling capability includes a blood separation filter. The filter has a plurality of pores sized to permit passage of selected blood constituents such as blood plasma through the device. The device has a separated blood conduit that extends beyond the outlet of the device and is shaped for easy penetration into a self-sealing septum of a blood analyzer. An annular shield extends from the device outlet beyond the conduit to prevent inadvertent contact of the conduit by a user.
