Devices and methods for facilitating fluid transport
Arrangements are provided including a base having a bore disposed therein extending from a first surface of the base through a second surface of the base, a fluid transport tube having a first end, a second end opposite the first end, and a lumen having an inner diameter, at least the second end of the tube being received within the bore of the base, and at least one fluid transport enhancing groove having at least a first section disposed in the second surface of the base and in fluid communication with the bore.
1. An arrangement comprising:
a base comprising a bore extending from a first surface of the base to a second surface opposite the first surface, wherein the second surface of the base comprises a plurality of radial grooves in fluid communication with and extending away from the bore, each of the plurality of radial grooves having a cross-sectional area that varies along its length;
a fluid transport tube coupled to the base and comprising a lumen therethrough, wherein the fluid transport tube is in fluid communication with the bore; and
an analyte quantification member comprising a reagent, wherein the analyte quantification member is in contact with the second surface of the base and overlies each of the plurality of radial grooves.
2. The arrangement of claim 1 , wherein the analyte quantification member overlies the bore.
3. The arrangement of claim 1 , wherein each of the plurality of radial grooves intersects the bore.
4. The arrangement of claim 1 , wherein a depth of each of the plurality of radial grooves decreases as the groove extends away from the bore.
5. The arrangement of claim 1 , wherein a width of each of the plurality of radial grooves increases as the groove extends away from the bore.
6. The arrangement of claim 1 further comprising a retaining member at least partially overlying the analyte quantification member, wherein the retaining member is coupled to the base such that a portion of the analyte quantification member is compressed between the retaining member and the base.
7. The arrangement of claim 1 further comprising a retaining member coupled to the base and at least partially overlying the analyte quantification member, wherein the retaining member is configured to permit optical communication with the analyte quantification member.
8. The arrangement of claim 1 , wherein the base comprises a cylindrical hub.
9. The arrangement of claim 8 further comprising an actuation member attached to the hub.
10. The arrangement of claim 1 , wherein an end of the fluid transport tube is positioned within the bore.
11. A system comprising:
an integrated analyte meter; and
the arrangement of claim 2 .
12. The system of claim 11 , wherein the integrated analyte meter is configured to be wearable or handheld.
13. The system of claim 11 , wherein the integrated analyte meter is constructed to perform multiple blood glucose concentration measurements.
