Abstract:
A method of extracting and analyzing bodily fluids from a patient at the point of care for the patient is provided. The method comprises establishing fluid communication between an analyte detection system and a bodily fluid in the patient. A portion of the bodily fluid is drawn from the patient. A first component of the bodily fluid is separated from the drawn portion, while the analyte detection system remains in fluid communication with the patient. The analyte detection system analyzes the first component to measure a concentration of an analyte in an accurate and timely manner.
Abstract:
An embodiment of a system for analyzing a body fluid of a patient comprises a fluid transport network that has a patient end configured to provide fluid communication with the body fluid in the patient and a fluid delivery point spaced from the patient end. A pump system is coupled to the fluid transport network. The pump system has an infusion mode in which the pump system is operable to pump an infusion fluid toward the patient end of the fluid transport network. The pump system has a draw mode in which the pump system is operable to draw the body fluid from the patient into the fluid transport network through the patient end. The system further comprises at least one fluid holder located near the fluid delivery point of the fluid transport network. The at least one fluid holder is positioned to receive a portion of the body fluid delivered to the delivery point by the fluid transport network. A laboratory-grade fluid analyzer is configured to receive the fluid holder and to measure at least one analyte in the portion of the body fluid.
Abstract:
A method for maintaining clear passageways in an extracorporeal blood flow system. The method comprises intermittently providing one or more anti-clotting agents to a passageway of the extracorporeal blood flow system. Also disclosed is an extracorporeal blood flow system. The system comprises a passageway, and a device operatively connected to provide one or more anti-clotting agents to a least a portion of said passageway.
Abstract:
In certain embodiments, a method of maintaining health of a patient uses an analyte detection system. The analyte detection system is coupled to the patient such that a bodily fluid of the patient is accessible to the analyte detection system. The method includes automatically initiating and conducting a measurement of an analyte in the bodily fluid using the analyte detection system. The method further includes determining a treatment dose for the patient based on the measurement using the analyte detection system.
Abstract:
A reagentless whole-blood analyte detection system that is capable of being deployed near a patient has a source capable of emitting a beam of radiation that includes a spectral band. The whole-blood system also has a detector in an optical path of the beam. The whole-blood system also has a housing that is configured to house the source and the detector. The whole-blood system also has a sample element that is situated in the optical path of the beam. The sample element has a sample cell and a sample cell wall that does not eliminate transmittance of the beam of radiation in the spectral band.
Abstract:
An apparatus for analyzing the composition of bodily fluid. The apparatus comprises a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid in a patient and at least one pump intermittently operable to draw a sample of bodily fluid from the patient. The apparatus further comprises a fluid analyzer positioned to analyze at least a portion of the sample and measure the presence of two or more analytes. Also disclosed is a method for analyzing the composition of a bodily fluid in a patient. The method comprises drawing a sample of the bodily fluid of the patient through a fluid handling network configured to maintain fluid communication with a bodily fluid in a patient. The method further comprises analyzing the at least a portion of the sample in a fluid analyzer to estimate the concentration of two or more analytes in the sample.
Abstract:
A fluid handling and analysis system comprises a fluid transport network comprising at least a first fluid passageway. The fluid transport network includes a patient end that is configured to maintain fluid communication with a bodily fluid in a patient. A sample analysis chamber and waste container are each accessible via the fluid transport network. A pump unit is in operative engagement with the fluid transport network. The pump unit has an infusion mode in which the pump unit is operable to deliver an infusion fluid to the patient through the patient end, and a sample draw mode in which the pump unit is operable to draw a volume of the bodily fluid from the patient through the patient end, towards the sample analysis chamber. A spectroscopic fluid analyzer is configured to analyze a sample of the bodily fluid while the sample is in the sample analysis chamber, and determine a concentration of at least one analyte. The fluid transport network and the pump unit are configured to draw a volume of the bodily fluid from the patient, isolate a fraction of the bodily fluid from the volume, and pass the fraction to the sample analysis chamber and then to the waste container.
Abstract:
In certain embodiments, a method samples a body fluid of a patient. The method includes providing a fluid handling system having one or more fluid passageways. The method further includes infusing an infusion fluid by way of a fluid handling system into a patient through one or more fluid passageways.
