摘要： Tilting of a drip chamber from its vertical axis during fluid administration can have negative effects upon the accuracy of systems configured for drop counting and/or for volumetric measurement of individual drops passing through the drip chamber. To address these negative effects, in accordance with one embodiment of the present disclosure, a fluid delivery system that measures the flow volume of a fluid delivery system is disclosed, which includes an imaging apparatus that captures a first image of a drip chamber while a drop is falling therein and a second image of the drip chamber with no drop. Portions of each image that are in substantially the same position in each image are subtracted.

摘要： Tilting of a drip chamber from its vertical axis during fluid administration can have negative effects upon the accuracy of systems configured for drop counting and/or for volumetric measurement of individual drops passing through the drip chamber. To address these negative effects, in accordance with one embodiment of the present disclosure, a fluid delivery system engages in a fluid control process that comprises determining an error parameter, based at least in part on a tilt signal, generating an error condition, and either holding the fluid flow at the present rate or stopping the flow.

摘要： An infusion system and method for controlling the fluid flow from a pump includes a pump system that has a controller that utilizes an algorithm to control the flow rate of fluid through tubing. A plurality of electrodes operatively contacts an electrically conductive portion of the tubing that is also acted upon by the pump system. The electrodes monitor electrical properties of the tubing and provide an electric signal indicative thereof to the controller, which varies the flow rate of the fluid through the tubing as a result of the electric signal.
