Abstract

Arrangements are provided including a fluid transport tube, or a needle, having a first end and a second end opposite the first end, and a lumen having an inner diameter. At least one fluid transport enhancing projection is disposed in the lumen and extends from the second end toward the first end. A discreet, wearable blood glucose monitor including such arrangements is also described.

Claims

1. An arrangement comprising:

a needle comprising a first end and a second end opposite the first end, and a lumen having an inner diameter and a longitudinal length; and

at least one fluid transport enhancing projection extending 0-100% of the longitudinal length of the lumen of the needle and extending toward the first end.
