ABSTRACT:
A lancet assembly having a blade designed for reduced pain that is used for piercing a patient's skin to cause capillary blood to flow for collection and testing. The blade has a shear percentage greater than conventional lancet blades to provide additional cutting action when the blade is being inserted into a puncture wound and a blade width smaller than conventional lancet blades. Reduced width and increased shear percentage result in reduced skin tear and penetration force, which therefore causes less pain to the patient during skin penetration.
