Abstract
An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may have a plurality of pores through which the liquid flows, and may be formed of a hydrophilic material that resists passage of air through the pores. The intravenous delivery system may further have a bubble point raising component that raises the bubble point of the anti-run-dry membrane. The bubble point raising component may, in some embodiments, be a high surface energy coating or additive.
