Ultrasonic air-in-line detector for a medication infusion system |
| abstract |
An ultrasonic air-in-line detection system for use in detecting air bubbles in the fluid line (306) of a disposable cassette mounted on a main pump unit which can accurately detect air bubbles in any type of fluid, whether clear or opaque. The system uses a windowing technique to determine when a threshold amount of air bubbles in a predetermined voulime of material pumped occurs, with the alarm being sounded only when this threshold amount of air bubbles in present in the window volume. The system of the present invention thus avoids so-called nuisance alarms due to the presence of small isolated air bubbles in the fluid due to the fluid pumped not having degassed. |
