Abstract:
In certain embodiments, a body fluid analyzing system includes a body fluid analyzer configured to be in fluid communication with a body fluid within a patient. The body fluid analyzing system further includes a communication interface configured to provide communication between the body fluid analyzer and a data system which includes at least one data file. The body fluid analyzer is configured to access the at least one data file via the communication interface.
Abstract:
A spectroscopic sample holder comprises a microporous sheet. The microporous sheet has a top surface, a bottom surface substantially parallel to the top surface, and at least one side surface oriented substantially perpendicular to the top and bottom surfaces. The side surface forms an exposed transit opening configured to contact a material sample and distribute the contacted material sample into the microporous sheet. The spectroscopic sample holder further comprises a first planar support member positioned on, and substantially parallel to, the top surface of the microporous sheet. The spectroscopic sample holder further comprises a second planar support member positioned on the bottom surface of the microporous sheet, and oriented substantially parallel to the first planar support member.
Abstract:
A device and method are provided for use with a noninvasive optical measurement system, such as a thermal gradient spectrometer, for improved determination of analyte concentrations within living tissue. In one embodiment, a wearable window is secured to a patient's forearm thereby isolating a measurement site on the patient's skin for determination of blood glucose levels. The wearable window effectively replaces a window of the spectrometer, and thus forms an interface between the patient's skin and a thermal mass window of the spectrometer. When the spectrometer must be temporarily removed from the patient's skin, such as to allow the patient mobility, the wearable window is left secured to the forearm so as to maintain a consistent measurement site on the skin. When the spectrometer is later reattached to the patient, the wearable window will again form an interface between the spectrometer and the same location of skin as before.
Abstract:
Methods and systems for determining the concentration of one or more analytes from a sample such as blood or plasma are described. The systems described herein can be configured to withdraw a certain volume of sample from a source of bodily fluid, direct a first portion of the withdrawn sample to an analyte monitoring system and return a second portion of the sample to the patient. The analyte monitoring system can include an automated blood withdrawal system that is configured to withdraw blood from the patient's vasculature at low pressure and/or withdrawal rates so as to reduce or prevent contamination of the withdrawn fluid from the infusion fluids.
Abstract:
Disclosed are methods and apparatus for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can also include a treatment dosing system to infuse or inject a treatment drug (e.g., insulin or glucose) and provide glycemic control. The dose of the treatment drug may be based on the concentration of the analyte or the average value for the concentration of the analyte and/or the rate of change of the value of the concentration of the analyte.
Abstract:
Systems and methods for determining a physiological parameter in a patient are provided. In certain embodiments, a system can include an analyte detection system configured to measure first analyte data in a fluid sample received from a patient, a medical sensor configured to measure second analyte data in the patient, and a processor configured to receive the first analyte data and the second analyte data and to determine a physiological parameter based at least in part on the first analyte data and the second analyte data. In certain such embodiments, the medical sensor may be a pulse oximeter, and the physiological parameter may include a cardiovascular parameter including, for example, cardiac output.
Abstract:
Some embodiments provide a system for synchronizing and configuring monitoring devices. In some embodiments, a patient monitoring device settings module is configured to automatically provide configuration settings to a plurality of patient monitoring devices. A monitoring device data module is configured to receive measurement data from at least one of the patient monitoring devices. An electronic medical records system interface is configured to provide patient data at least partially derived from the received measurement data to an electronic medical records system. A patient records interface is configured to provide patient data to at least one of the patient monitoring devices.
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:
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.
