ABSTRACT:
A disposable lancet for use in obtaining blood samples comprises a plastic housing and a resilient blade in a retracted position within the housing, the blade being bent in an arcuate form to provide a source of spring energy biasing the piercing edge of the blade toward an opening in the housing. A releasable trigger means retains the blade in its retracted position in the housing but is readily operable to release the blade to cause the part of the blade with the piercing edge to be driven through the opening a predetermined distance.
