Method and apparatus for improving fluidic flow and sample capture
First Claim
1. A body fluid sampling device for use on a patient, the device comprising:
- a cartridge;
at least one penetrating member mounted on the cartridge; and
a wicking material positioned to substantially surround at least one penetrating member exit on the cartridge so as to acquire body fluid flowing from a wound on the patient created by actuating the penetrating member.

Abstract
A system and method is provided for the capture of bodily fluid upon lancing of a patient. In one embodiment, the fluid sample capture aperture mesh (320) ring is placed in the pathway of a finger penetrating member (340). The aperture mesh ring has a center clearance area that allows the penetrating member to pierce the skin unobstructed. The aperture mesh ring may contain a series of fluid sampling meshes as to allow the release bodily fluid to “wick” into the fluid sampling meshes for transport to the respective sensor. The invention may also relate to a method of improving the fluidic flow through a membrane mesh structure for the transportation of bodily fluids from a point of sampling to a point of measurement.

2. A body fluid sampling device for use on a patient, the device comprising:
-
a cartridge having a radial-disc shape; a plurality of penetrating members mounted on said cartridge; a sensory material on a first side of said cartridge, said sensory material sufficient for detecting at least one analyte; and a wicking material positioned to substantially surround a penetrating member exit so as to acquire body fluid flowing from a wound created by the penetrating member and draw the body fluid to the sensory material.

16. A body fluid sampling system for measuring analyte levels in the body fluid, said system comprising:
-
a housing having a transparent window; a cartridge in said housing; a plurality of penetrating member in said cartridge; a sensory material on a first side of said cartridge, said sensory material sufficient for detecting at least one analyte; a wicking material positioned to substantially surround a penetrating member exit so as to acquire body fluid flowing from a wound created by the penetrating member. - View Dependent Claims (17)

18. A device comprising:
-
a mesh membrane; an adhesive integrated onto and within the mesh membrane for defining a fluid channel within the mesh membrane structure, wherein the adhesive is hydrophobic and upon integration into the mesh, will prohibit fluidic flow where flow is not desirable by design; wherein the adhesive integrate onto and within a mesh membrane for defining a fluid channel within the mesh membrane structure.

-
19. A device comprising:
-
a mesh membrane; hydrophobic and hydrophilic adhesives within the mesh membrane for the enhancement of fluidic capture and transport flow, wherein the developed surface energy properties of specific adhesive formulations has allowed the availability of extreme hydrophobic and hydrophilic properties and various viscosities as to promote absorption into the pores of the mesh membranes, creating pressure sensitive adhesives along with fluid attractive properties to direct optimal fluid capture, transport, and flow.

20. An actuation device comprising:
a combined lancing and blood sample analysis device in a single disposable cartridge, said cartridge does not have conducive leads and includes a wicking material surrounding a penetrating member exit.
-
21. A method comprising:
-
providing a fluid sampling device comprising a cartridge, at least one penetrating member mounted on the cartridge, and a wicking material positioned to substantially surround at least one penetrating member exit on said cartridge so as to acquire body fluid flowing from a wound on the patient created by actuating the penetrating member; positioning the cartridge so that launching the penetrating member creates a wound on the patient which expresses body fluid; using the wicking member to capture fluid expressed from the wound. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
