Handheld medical diagnostic device with lancet and sample transfer
First Claim
1. 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 housing assembly comprising:
- a housing structure comprising;
an outer facing side;
an inner facing side;
an opening located at the outer facing side that is arranged and configured to align with a lancet port of the medical diagnostic device; and
a floor that extends between the outer facing side and the inner facing side;
a reagent material located on the floor and within the housing structure; and
a lancet structure located in the housing structure, the lancet structure comprising a skin penetrating end aligned initially in a first plane with the opening and a blood transport portion adjacent the skin penetrating end, wherein the skin penetrating end is configured to extend in the first plane when extended through the opening and, when extended through the opening, is shaped and sized to penetrate the patient'"'"'s skin at the skin site to provide an amount of blood, and further is configured to be extended and retracted by a drive member, and a biasing mechanism is configured to force the lancet structure toward the floor when the lancet is retracted to a second plane parallel to the first plane and offset from the opening, the drive member is configured to pass over the lancet structure when the drive member is moved toward the opening and the lancet structure is in the second plane, and the blood transport portion being arranged and configured to receive the amount of blood from the skin penetrating end in the second plane and to carry the amount of blood away from the skin site and to the reagent material.
