Claims10
A lancet sheet providing multiple lancets for a lancet housing assembly for use in a portable handheld medical diagnostic device for sampling bodily fluids from a skin site of a patient, the lancet sheet comprising:
- a first removable ledge and a second removable ledge, each formed of material forming the lancet sheet;
- a plurality of lancet structures formed of material forming the lancet sheet, the plurality of lancet structures comprising a skin penetrating end and a blood transport portion adjacent the skin penetrating end, wherein the skin penetrating end is shaped and sized to penetrate the patient's skin at the skin site to provide an amount of blood;
- and
- a plurality of spring components formed of material that forms the lancet sheet that releasably connect the plurality of lancet structures to the first and the second removable ledges, wherein the first and the second removeable ledges are connected to the plurality of lancet structures via the plurality of spring components so as to be able to be flexed relative to a plane of the lancet sheet and configured to be broken from the plurality of lancet structures when the first and the second removeable ledges are flexed relative to the plurality of lancet structures.
