Abstract
A lock for a syringe which typically may be used with an aspirating biopsy needle. A malleable sheet defining a central, cutaway portion extending through the edge of the sheet and having foldable tabs positioned on the outer edge of the sheet is carried on a syringe barrel and may be used to lock the syringe plunger in a predetermined position. Thus a vacuum may be drawn in the syringe by the plunger with the plunger then being locked to provide suction to the aspirating biopsy needle.
