Device for sampling bodily fluids
First Claim
1. Apparatus for sampling bodily fluids comprising:
- a plurality of elongated lancing mediums, each having a skin-piercing end adapted to be displaced against a skin site to make an incision and produce a droplet of bodily fluid;
a plurality of transport mediums, each transport medium oriented sufficiently close to a respective lancing medium to retain a droplet of bodily fluid between the transport medium and the respective lancing medium by capillary action;
a mechanism adapted to index said lancing and transport mediums into alignment with said displacement device; and
a displacement device adapted to relatively displace a lancing medium and a respective transport medium aligned with said displacement device to move the droplet of bodily fluid away from said skin site.

Abstract
A bodily fluid sampling device comprising a lancet which can be advanced against a skin-piercing site to produce a droplet of bodily fluid. A transport medium is positioned sufficiently close to the lancing medium to retain a droplet of bodily fluid therebetween by capillary action. One of the two mediums has hydrophobic material on its surface and the other hydrophilic. Various mechanisms are provided for relatively displacing the lancing and transport medium to move the droplet of bodily fluid away from the skin-piercing end. Furthermore, multiple lancet assemblies may be provided in a barrel or disk configuration and indexed to the displacing mechanisms for sampling a skin site.

14. An apparatus for obtaining a sample of bodily fluid, comprising:
-
a housing with individual compartments; a plurality of lancing medium and transport medium pairs, wherein a first lancing medium and transport medium pair is contained in a first compartment and a second lancing medium and transport medium pair is contained in a second compartment, wherein the first and second compartments are adapted to maintain separate sterile environments, and wherein the lancing medium and the transport medium in a pair are individually extendable to lance the skin and move a droplet of bodily fluid away from the skin surface. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method, comprising:
-
aligning a first lancing medium and a first transport medium with an actuating device, the first lancing medium and the first transport medium being adjacent one another in a first compartment; moving the first lancing medium with the actuating device to penetrate a skin surface at a penetration site; moving a first body fluid sample from the penetration site away from the penetration site with the first transport medium; applying the first body fluid sample moved with the first transport medium to a first test element; testing the first body fluid sample for an analyte with the first test element; positioning the first lancing medium, first transport medium and first compartment away from alignment with the actuating device; and aligning a second lancing medium and a second transport medium with the actuating device, the second lancing medium and the second transport medium being adjacent one another in a second compartment adapted to maintain a separate sterile environment from the first compartment. - View Dependent Claims (22, 23, 24, 25)
