Drip chamber with hydrophobic interior surface

摘要

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.

1. A drip chamber for an infusion tube, comprising:
a first end including a drip tube; a second end including an exit port; a wall extending between the first end and the second end, the wall having an interior surface including a hydrophobic portion, and having a space defined by the interior surface of the wall and the first and second ends; and the hydrophobic portion configured for refracting substantially all light being transmitted through the wall, and eliminating substantially all reflectance or glare formed on the wall; wherein the hydrophobic portion of the interior surface repels liquid contacting the hydrophobic portion; and, the hydrophobic portion of the interior surface enables the 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.
