1. A drip chamber for an infusion tube, comprising:
- a wall extending between a first end and a second end, the wall enclosing a space defined by an interior surface of the wall, the interior surface including a hydrophobic portion configured to repel liquid contacting the hydrophobic portion and extending from said first end to said second end,wherein the hydrophobic portion is configured for refracting substantially all light being transmitted through the wall, and eliminating substantially all reflectance or glare formed on the wall.

Abstract
A drip chamber for an infusion tube, including: a first end including a drip tube; a second end including an exit port; and a wall connecting the first and second ends and including an interior surface with a hydrophobic portion. The drip chamber includes a space enclosed by the interior wall and the first and second ends. The hydrophobic portion of the interior surface repels liquid contacting the hydrophobic coating. The hydrophobic portion of the interior surface enables light to refract through the hydrophobic portion and the wall in the same manner as is the case when the hydrophobic portion is not present on the interior surface.

12. A method of forming a drip chamber for an infusion tube, comprising:
-
enclosing a space defined by an interior surface of a wall, the space extending between a first end and a second end and the interior surface including a hydrophobic portion, wherein; the hydrophobic portion of the interior surface repels liquid contacting the hydrophobic portion; the hydrophobic portion of the interior surface is configured for refracting substantially all light being transmitted through the wall, and eliminates substantially all reflectance or glare formed on the wall; and the hydrophobic portion of the interior surface extends between said first end and said second end.

13. A drip chamber for an infusion tube, comprising:
-
a wall extending between a first end and a second end, the wall enclosing a space defined by an interior surface of the wall, the interior surface including a hydrophobic portion configured to repel liquid contacting the hydrophobic portion and extending from said first end to said second end, wherein the hydrophobic portion is configured for refracting substantially all light being transmitted through the wall, and eliminating substantially all reflectance or glare formed on the wall, and wherein the hydrophobic portion of the interior surface reflects less than one tenth of one percent of light incident upon the hydrophobic portion of the interior surface.
