ABSTRACT:
An automatic blood sampling device is provided with a housing (12, 14, 18, 20), a reciprocable shaft (50) disposed in the housing (12, 14, 18, 20), and a lancet (40) operatively coupled to the shaft (50). The lancet (40) is movable between a retracted position in which the lancet (40) is disposed within the housing (12, 14, 18, 20) and an extended position in which the lancet (40) extends outside of the housing (12, 14, 18, 20).
The blood sampling device includes means for retaining the lancet (40) in its retracted position, means (51) for causing the lancet (40) to automatically move from its retracted position to its extended position, and means for generating a reduced internal pressure within an area in the housing (12, 14, 18, 20) as the lancet (40) moves from its retracted position to its extended position to facilitate drawing blood from a skin puncture to be made by the lancet (40) into an interior portion of the housing (12, 14, 18, 20), the internal pressure being less than the ambient pressure outside of the housing (12, 14, 18, 20) of the sampling device.
