Abstract
Abstract A disposable lancing element is adapted for use in a lancing device for making an incision through a user's skin. The lancing element includes a body which defines a longitudinal axis, and has a skin-lancing member projecting from a front end thereof. A capillary tube is mounted in the body in laterally spaced relationship to the skin-lancing member and is slidable longitudinally relative to the body so as to be extended forwardly past the skin-lancing member. The body includes a plurality of circumferentially spaced, radially outwardly projecting bosses formed thereon for guiding the disposable element installation in a carrier element. The skin-lancing member may comprise a plurality of needles or barbs arranged in parallel side-by-side relationship. In lieu of a skin-lancing member, the disposable element may possess a longitudinal through-hole for conducting a skin-piercing laser light beam or pressurized fluid. A capillary tube may have an outwardly flared lower (inlet) end. A capillary tube may possess a sensor for sensing a level of fluid rising therein.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
64 words
A device for expressing body fluid from an incision formed on a skin surface comprising: a housing member having an end; a disposable lancing member mounted within the housing; and a stimulating member having a first end mounted within the housing and a second end adapted to extend beyond the end of the housing, said stimulating member being longitudinally slidable relative to said housing.
Claim 2
Independent Claim
64 words
A device for expressing body fluid from an incision formed on a skin surface comprising: a housing member having an end; a disposable lancing member mounted within the housing; and a stimulating member having a first end mounted within the housing and a second end adapted to extend beyond the end of the housing, said stimulating member being longitudinally slidable relative to said housing.
Claim 3
Dependent Claim
13 words
The device of claim 1 , wherein said stimulating member is substantially cylindrical.
Claim 4
Dependent Claim
16 words
The device of claim 1 further comprising an inner sleeve mounted concentrically within said stimulating member.
Claim 5
Independent Claim
89 words
A method of obtaining a sample of body fluid comprising the steps of: (a) lancing a skin surface to form an incision therein; (b) applying a force to the skin surface surrounding the incision so as to form a depressed ring of body tissue, thereby spreading the incision open; (c) withdrawing the force applied to the skin surface thereby causing said incision to close; and (d) repeating steps (b) and (c) a sufficient number of times to cause a sample if body fluid to be expressed from said incision.
