METHOD AND APPARATUS FOR ASPIRATING LIQUID FROM A CONTAINER

摘要

A method and apparatus (10) for aspirating a liquid (L) (e.g., blood) from a container (C) uses an electrically biased thermistor element (20), mounted proximate the tip of a liquid-aspirating probe (12), to determine that the probe is safely submerged within a body of liquid to be aspirated at all times during the aspiration process. Also disclosed are different aspiration probe assemblies that are useful in the method and apparatus of the invention.
