Abstract
Abstract Body fluid is sampled from a skin incision by placing a ring against the skin and repeatedly applying an elastic pressing force to the ring, whereby a stimulator surface of the ring depresses a ring of skin and body tissue in surrounding relationship to the incision to force body fluid from the incision. The stimulator surface is inclined at an angle of 10 to 65 degrees; a width of the stimulator surface is from 5 mm to 20 mm, and an inner diameter of the stimulator surface is no less than 6.0 mm.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
113 words
A sampling device for sampling blood or interstitial fluid by creating an opening in a skin surface and assisting in expressing fluid therefrom, comprising: a housing having a longitudinal axis; and a stimulator surface attached to said housing and adapted to contact the skin surface, the stimulator surface defining an interior opening having a dimension of at least 6.0 mm, the stimulator surface being inclined relative to a plane oriented perpendicular to the axis, the inclination being radially inwardly and longitudinally rearwardly, the inclination relative to the plane being from 10 to 65 degrees such that body fluid is urged toward the opening in the skin surface by contact with the stimulator surface.
Claim 2
Dependent Claim
113 words
A sampling device for sampling blood or interstitial fluid by creating an opening in a skin surface and assisting in expressing fluid therefrom, comprising: a housing having a longitudinal axis; and a stimulator surface attached to said housing and adapted to contact the skin surface, the stimulator surface defining an interior opening having a dimension of at least 6.0 mm, the stimulator surface being inclined relative to a plane oriented perpendicular to the axis, the inclination being radially inwardly and longitudinally rearwardly, the inclination relative to the plane being from 10 to 65 degrees such that body fluid is urged toward the opening in the skin surface by contact with the stimulator surface.
