An apparatus and method is disclosed for obtaining and measuring constituents in a sample of body fluid. The apparatus includes a member which is sized to penetrate into at least the dermal layer of skin to collect a sample of body fluid located within the dermal layer.

Interstitial fluid collection and constituent measurement

A sampling apparatus for interstitial fluid includes a pressure ring surrounding a collection needle. The pressure ring and needle are movable relative to one another for the ring to first engage a patient's skin surface prior to insertion of the needle.

Enhanced interstitial fluid collection

An apparatus for collecting a body fluid for testing for an analyte includes a needle for penetrating a patient's skin to access the fluid within the skin. The needle has a hollow body extending from a first end to a second end. An interior surface of the body defines a fluid pathway extending between the ends. The second end is positioned to deposit fluid for testing. The first end has a beveled face on a front side of the body. The beveled face terminates at a penetration tip with the beveled face having an opening in communication with the fluid pathway. The penetration tip is burnished to a rounded shape and bent to facilitate low pain and rapid fluid collection.
