Abstract
An airtrap for a medical or physiological fluid in one embodiment includes a conical housing having a radius that increases from its top to its bottom when the housing is positioned for operation; a medical or physiological fluid inlet located at an upper portion of the conical housing; a medical or physiological fluid outlet located at a lower portion of the conical housing, the inlet and the outlet positioned and arranged so that medical or physiological fluid spirals in an increasing arc around an inside of the conical housing downwardly from the inlet to the outlet; and a gas collection area located at an upper portion of the conical housing. In another embodiment, the airtrap is shaped like a seahorse having a head section and a tail section. Any of the airtraps herein may be used for example in blood sets, peritoneal dialysis cassette tubing, and drug delivery sets.
