ABSTRACT:
A disposable automatic surgical lancet having a plastic spring arm molded integral with a central frame piece which is part of the housing. The free end of the spring arm carries a holder for a lancet blade or needle. The spring arm can be cocked in a retracted, stressed position from which it is released by pushing in on the front wall of the housing. When released, the spring arm carries the lancet blade or needle upward to project through an opening in a concave depression on the top of the housing where the patient's finger tip rests. A lock arrangement inside the housing holds the front wall in its pushed-in position so the lancet cannot be used again inadvertently.
