Claim:
1. An elongated fluid degassing apparatus, comprising: an outer flexible, liquid-impermeable jacket having an inner surface defining a jacket chamber along a central axis of said jacket, wherein said jacket has an inlet opening to said jacket chamber and an outlet opening to said jacket chamber, and an aspect ratio of at least 2:1; a tubular membrane extending axially in said jacket chamber along a mutual axial length, said tubular membrane having a first open end, the membrane defining a lumen with a luminal axis that is substantially parallel with said central axis, the membrane forming a gas-permeable, liquid-impermeable barrier between said jacket chamber and said lumen; and one or more spacer members extending continuously in said jacket chamber substantially along an entirety of said mutual axial length to maintain said membrane in a spaced relationship from channel regions of said inner surface of said jacket, with a radial gap being defined radially between said membrane and said channel regions of said inner surface of said jacket, said radial gap being between 50-500 micrometers.
