摘要： A fluid delivery system having a closed-loop control process for delivering a medical fluid to a patient. A fluid infusion system includes a pump for delivering a fluid to a patient via an administration tube. A flow sensor associated with the administration tube provides an indication of the actual flow rate of fluid in the administration tube. Such a flow sensor may comprise a positive displacement flow sensor constructed using micro-fabrication and/or micro-molding techniques. A reader reads the actual flow rate signal and provides an indication to a controller for controlling the pump. The flow rate information can also be used for providing status information, such as the existence of a blockage in the fluid delivery system.

摘要： An optical access disconnect system is useful for detecting the presence of blood. The optical access disconnect system includes one or more optical sensors placed near an access site of a patient, the optical sensors suitable for detecting the presence of blood, especially by detecting a difference in light reflected or absorbed by blood. The optical access disconnect system may also be used as an interlock to assure compliance. A detector may be placed adjacent the access site to detect the access needle, or an object or mark on the access needle or fluid line. A therapy machine, such as a dialysis machine, may be programmed not to start or continue operation unless the needle or fluid line is detected. The detector may be one of the optical sensors, calibrated or adjusted to detect a mark on the needle or access line, or may be another type of detector.

摘要： A method and system for detecting an inclusion within an infusion system. The method includes monitoring an output signal of a flowrate sensor as fluid flows through an infusion system. The output signal is then converted with a noise reduction filter to obtain a filtered output signal. The filtered output signal is compared to a threshold value and an alarm is activated if the filtered output signal falls below a desired threshold, thereby indicating an occlusion within the infusion system.
