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： A fluid medication delivery system comprises a primary medication reservoir, a secondary medication reservoir, an infusion pump, a first valve assembly, a second valve assembly, a first y-site, and a fluid flow sensor assembly. The primary medication reservoir has a first fluid. The secondary medication reservoir has a second fluid. The infusion pump pumps fluid from at least one of the primary medication reservoir and the secondary medication reservoir. The first valve assembly controls the flow of fluid from the primary medication reservoir in a first fluid line segment. The second valve assembly controls the flow of fluid from the secondary medication reservoir in a second fluid line segment. The fluid flow sensor assembly determines the flow rate of a fluid from the secondary medication reservoir in the second fluid line segment.

摘要： A method for identifying artifacts occurring during a measurement of the concentration of an analyte in a biological sample by means of an apparatus that employs temperature-controlled optical probes, introduces electromagnetic radiation into tissue, and collects and detects radiation emitted at a distance from the point at which the electromagnetic radiation is introduced. The values of intensity of radiation emitted at different wavelengths, at different distances between the light introduction site(s) and the light collection site(s), and at different temperatures are collected and used in the method to generate a relationship between these values and the concentration of an analyte in the tissue or the disease state of a patient. The method involves the use of an algorithm that identifies artifacts in the data resulting from motion of the patient and allows the rejection of data sets that contain these artifacts. The algorithm identifies sudden changes in the magnitude and direction in a sequence of collected signals.
