Date May 13, 1993In a method to determine or regulate flows or flow rates of liquids such as those used in medical infusion systems, optical imaging means are used for real flow measuring. The increase in volume of drops hanging at an outlet and the increase of volume of liquid gathered in a container can be measured by image acquisition and image processing. This increase of volume represents a real time flow. As an example, signals obtained from these measurements can be used to control or adjust volume flow for medical treatment or medical diagnosis. An apparatus to carry out such a method can be composed of devices well known per se.</p> |
