    摘要: The use of an optical or other measurement in a blood access system enables the determination of a fluid sample appropriate for measurement on a real time basis. This information can be used to control the blood access system and related measurement processes. The determination can be based on, for example, at least one of: optical density, optical scatter, analyte level, temperature, the absolute level of any of the preceding, the stability of any of the preceding, the rate of change of any of the preceding, or the value of any of the preceding relative to another determination. The determination can be made using, for example, at least one of: electrochemical sensor, ion specific electrode, capacitance measurement, impedance measurement, inductance measurement, conductivity measurement, optical measurement, and ultrasound measurement. The present invention relates to determination of the quality of a biological sample in which determination of an analyte concentration is to be made, and various methods and apparatuses related thereto. An evaluation of sample quality can be made by monitoring the temporal changes in the sample properties or characteristics as the biological sample is procured or measured. The methods and apparatuses described herein can be used to evaluate the temporal characteristics of a sample during sample acquisition and/or during determination of the sample analyte or parameter of interest. The sample quality assurance methods and apparatuses described herein can thus be used to ensure that a valid sample has been procured by or presented to an instrument or measurement system for analyte determination, thereby preventing the measurement and reporting of analyte values for a sample that is unstable or otherwise non-representative of the biological system from which the sample was obtained.

    摘要: The present invention relates to a blood analyte measurement system for the procurement of blood samples for measurement of blood properties such as analyte concentration or analyte presence. A blood access system can be coupled with a measurement system such as an electrochemical sensor, and can also be used with other measurement modalities. Embodiments of the present invention can facilitate accurate measurement of blood glucose by the clinician in a sterile manner. Embodiments of the present invention can also enable the calibration of the sensor at one or more calibration points. One desired analyte of measurement is glucose for the effective implementation of glycemic control protocols. Embodiments of the present invention can also be used for the measurement of other analytes such as arterial blood gases, lactate, hemoglobin, potassium and urea. Additionally, embodiments of the present invention can function effectively on a variety of blood access points and specifically enables glucose monitoring in an existing arterial line that is already in place for hemodynamic monitoring. The present invention does not consume a significant amount of blood. Some embodiments of the present invention can re-infuse the blood into the patient, which can facilitate operation of the system in a sterile manner.

    摘要: The present invention embodies a method and an injector adapted to incorporate this method, for keeping a patient's vein open during an intravenous contrast injector procedure without injecting a saline solution from a separate syringe. The injector includes a controller having a programmable software module to allow an operator to configure the injector to push some contrast media fluid through an injection site and then retract a plunger drive ram. A syringe is adapted to allow a patient's blood pressure to move the syringe plunger back towards its starting position, thus enabling a patient's blood to pass through the injection site. Alternatively, the syringe is adapted with an elastic plunger which as it enlarges and contracts facilitating fluid communication through the injection site. Additionally, the plunger drive ram can be adapted to gradually pull as well as push the plunger, thereby causing fluid to flow across the injection site.

    摘要: A fluid infusion device and a method of using the same. The device includes an outer, flexible guide catheter having a distal end for introduction beneath the skull of a patient and a proximal end remaining external of the patient. A flexible infusion fiber is located within the guide catheter and has a distal end extending outwardly from the guide catheter to be located in a target area within the patient's brain. The infusion fiber can be fixed or axially movable within the guide catheter. In the latter embodiment, the proximal end of the infusion fiber extending outwardly from the guide catheter can be manipulated to locate the distal end of the infusion fiber in the target area. An infusion pump is connected to the proximal end of the infusion fiber to infuse a minute quantity of fluid at an extremely low flow rate into the brain of the patient.
