Abstract
A biologic fluid sample transfer device and method is provided. The device includes an outer casing and a lance. The outer casing has a tip with an exterior surface and a bore extending lengthwise through the tip and out to the exterior surface of the tip to form an aperture in the exterior surface. The lance has a length extending between an operating end and a sample end. The lance includes a seal segment contiguous with the sample end. The seal segment extends a distance lengthwise and has a constant cross-sectional geometry. The transfer device is selectively disposable in an empty volume position and a sample volume position by relative lengthwise movement between the outer casing and the lance. In the empty volume position, the sample end extends outside of the aperture. In the sample volume position, the sample end of the lance is disposed within the bore a distance away from the aperture. The seal segment of the lance forms an interference fit with the bore, which interference fit is operable to create a seal between the seal segment and the bore.
