| 20090213360 | DEVICE AND METHOD FOR IN VITRO DETERMINATION OF ANALYTE CONCENTRATION WITHIN BODY FLUIDS - 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. | 08-27-2009 |
| 20090326343 | FLUID HANDLING CASSETTE HAVING A SPECTROSCOPIC SAMPLE CELL - A fluid handling module is configured for removable engagement with a reusable main fluid handling instrument. The module includes a module housing and a first fluid passageway extending from the module housing. The first fluid passageway has a patient end remote from the housing. The first fluid passageway is configured to provide fluid communication with a bodily fluid in a patient. A fluid component separator is in fluid communication with the first fluid passageway. The fluid component separator is configured to separate at least one component from a portion of the bodily fluid drawn from the patient. A spectroscopic sample cell is configured to hold at least a portion of the first component. | 12-31-2009 |
| 20100030137 | APPARATUS AND METHODS FOR ANALYZING BODY FLUID SAMPLES - An apparatus is provided for monitoring a predetermined parameter of a patient's body fluid while infusing an infusion fluid into the patient. The apparatus comprises an infusion line and a catheter configured for insertion into a blood vessel of the patient, and a reversible infusion pump connected between a source of an infusion fluid and the infusion line and catheter. The apparatus further comprises a body fluid sensor assembly mounted in fluid communication with the infusion line and which includes a first sensor and a sample cell. The first sensor provides a signal indicative of a predetermined parameter of any fluid present in the infusion line. The sample cell is substantially transmissive to light comprising a wavelength λ. The apparatus further comprises a controller that is configured to operate the infusion pump in a forward direction so as to pump the infusion fluid through the infusion line and catheter for infusion into the patient. The controller is configured to intermittently interrupt its operating of the infusion pump in the forward direction to operate the infusion pump in a rearward direction so as to draw a body fluid sample from the patient through the catheter and infusion line. The body fluid sample drawn from the patient is disposed such that a first portion of the body fluid sample is in sensing contact with the first sensor of the body fluid sensor assembly, and a second portion of the body fluid sample is disposed within the sample cell of the body fluid sensor assembly. The controller further is configured to monitor the signal provided by the first sensor of the body fluid sensor assembly and to detect a change in the signal indicative of the arrival of the body fluid sample at the first sensor. The controller, in response to detecting the arrival of the body fluid sample at the first sensor, is configured to cease its operating of the infusion pump in the rearward direction. The signal produced by the first sensor provides an indication of a predetermined parameter of the patient's body fluid when the body fluid sample is in sensing contact with the first sensor. | 02-04-2010 |
