Universal Sampling Cap

摘要

A sampling port (10) has a generally tubular body (12) defined by a wall (18) arranged about an axis (42) which defines a space (21) for a sampling vial (72, 102). The wall (18) has a waisted region (60) intermediate a base (16) and an open end (20). The wall (18) is expandable radially in at least the waisted region (60) to accommodate different sized sampling vails (72, 102).

1. A sampling port having:
a body having a space having a longitudinal direction, an open end and adapted to receive a sampling vial; a cannula having an axis and extending longitudinally along the space with a pointed end facing the open end, whereby a sampling vial passed into the space from the open end may be impaled on the cannula; the space defined by a wall arranged about the axis and extending generally axially; the wall having a waisted region intermediate a base end and the open end so as to define a waisted space region, having, in axial end view, a cross section smaller than cross sections at the open end and the base end; the wall being radially expandable in at least the waisted region whereby the size of at least the waisted space region is expandable.
