US Patent:

20190167914, Jun 6, 2019

Filed:

Feb 11, 2019

Appl. No.:

16/272669

Inventors:

- Franklin Lakes NJ, US
Weston O. Whitaker - Riverton UT, US
Jon Larsen - Riverton UT, US

International Classification:

A61M 5/38
B01D 53/62
A61M 5/44
A61M 5/14
A61M 5/36

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.

Abstract:

An air stop membrane can be used within an IV set to maintain a fluid column within the IV set downstream of the membrane even after a fluid bag has emptied. By maintaining a fluid column downstream of the membrane, air is prevented from entering into the tubing that couples the IV set to a vascular access device. For this reason, once a fluid bag has emptied, a new fluid bag can be coupled to the IV set without needing to re-prime the IV set. Therefore, a clinician need not be present as a fluid bag is emptying to ensure that air does not enter the tubing.
