Lancing device

DETAILED DESCRIPTION That which is claimed is: 1.
An integrated lancing device which comprises: a generally U-shaped spring member defining a pair of arms having free ends; a lance blade carried in transverse position on one of said arms adjacent said free end, the free end of said one arm defining a trigger projection positioned substantially along the axis of said one arm; the other of said pair of arms carrying a trigger member as an integral part thereof, said trigger member extending toward said trigger projection, whereby said arms may be flexed outwardly into a cocked position and held there by engagement of the trigger projection by the trigger member, and the trigger member may be manipulated to cause the arms to suddenly flex together to cause the lance blade to strike a positioned body part of a patient, the other of said pair of arms having a free end and defining, adjacent its free end, an outer platform defining a first aperture and an inner platform defining a second aperture, said inner platform being positioned within the first aperture and being connected to said outer platform through a flexible connection member, said trigger member being carried in a position to move with the flexing of the inner platform at said connection member, said lance blade being positioned to pass through the second aperture as the arms flex together, whereby pressing with the body part of the inner platform of the lancing device in cocked position causes the trigger member to release the trigger projection and the lance blade to strike said body part.
2.
The integrated lancing device of claim 1 which is free of side walls.
3.
The integrated lancing device of claim 1 in which said trigger member consists essentially of a single, straight, upstanding post positioned transversely to the other of said pair of arms, said post carrying a laterally projecting trigger arm capable of engaging said trigger projection to hold the pair of arms in cocked position.
4.
The integrated lancing device of claim 1 in which said outer and inner platforms are of generally circular shape
