| 20090137910 | ORGAN OXYGENATION STATE MONITOR AND METHOD - One aspect of the invention provides a patient tissue state monitoring system with a light source; a light detector; a probe adapted to be inserted into a patient to transmit light from the light source to an organ tissue site and to direct light from the organ tissue site to the detector; and a processor programmed to determine tissue state with respect to a tissue site pre-dysoxia point from a fluorescence emission detected by the detector (such as by determining tissue NADH concentration) and to provide an indication of tissue state through an output device (such as by displaying a numerical value corresponding to the fluorescence emission). Another aspect of the invention provides a method of monitoring a patient tissue state including the following steps: monitoring an aerobic energy production level of an organ tissue site (such as tissue within the patient's gastro-intestinal tract, bladder and/or urethra); determining tissue state with respect to a tissue site pre-dysoxia point from the monitored aerobic energy production level; and providing an output of the tissue state (such as by displaying a numerical value corresponding to the fluorescence emission). | 05-28-2009 |
| 20100042017 | DUAL BLADE LANCING TEST STRIP - An integrated lancing test strip includes a pair of blade members that each have a lancing tip that are configured to lance skin. A pair of spacer members connect the blade members together such that the blade members define an internal capillary. A test strip is positioned along the internal capillary, and the test strip is configured to test analyte levels in the bodily fluid. During use, the lancing tips form one or more incisions in the skin. The fluid from the incisions is drawn via capillary action through the internal capillary and onto the test strip. | 02-18-2010 |
| 20100045993 | METHOD OF DETECTING ANALYTE - A system and method is provided for detecting concentration of an analyte in a fluid. The method comprises detecting an optical property of a first region of two or more regions in a system, the first region located in a container having a reservoir for one or more modifiers of one or more optical properties of the first region. The movement of the one or more modifiers is responsive to changes in concentration of the analyte. A next step detects an optical property of a second region of the two or more regions in the system, the second region located in a container having a reservoir for one or more modifiers of one or more optical properties of the second region. The movement of the one or more modifiers is responsive to changes in concentration of a compound, where the compound is something other than the analyte. The detected optical property of the first region and the detected optical property of the second region are used in embodiments to separate the effect of the analyte on the detected optical property of the first region from the effect of the compound, where the compound is an interfering compound. | 02-25-2010 |
| 20100049015 | SPECIFICITY OF ANALYTE DETECTION IN ETALONS - A system and method is provided for detecting concentration of an analyte in a fluid. A first container includes (i) an optical cavity detection region, (ii) a reservoir for one or more modifiers of one or more optical properties of the optical cavity detection region, and (iii) a set of one or more bounding regions through which objects in the fluid can transfer into the container. The optical cavity detection region and the reservoir define separate areas of the first container. The movement of the one or more modifiers between the reservoir and the optical cavity detection region is responsive to changes in concentration of the analyte. A second container includes an optical cavity detection region, and a set of one or more bounding regions through which objects in the fluid can transfer into the container. Also provided are optical components for guiding light into the optical cavity detection regions of the first and second containers. | 02-25-2010 |
| 20100106058 | BLOOD AND INTERSTITIAL FLUID SAMPLING DEVICE - A device and method for lancing a patient, virtually simultaneously producing and collecting a small fluid sample from a body. The device comprises a blood collection system including a lancing needle ( | 04-29-2010 |
| 20100113977 | INTEGRATED DISPOSABLE FOR AUTOMATIC OR MANUAL BLOOD DOSING - An integrated sampling device defines a first opening and a second opening. The first opening is connected to a channel for drawing fluid automatically towards a test media upon incision by an incision portion. The second opening is positioned over the test media allowing manual sampling of fluid if the channel fails to draw a sufficient amount of fluid onto the test media. | 05-06-2010 |
| 20100222656 | METHODS AND APPARATUS FOR SAMPLING AND ANALYZING BODY FLUID - A sampling device for sampling body fluid includes a lancet for making an incision, a capillary tube for drawing-up body fluid from the incision, and a test strip affixed to an upper end of the capillary tube for receiving the fluid. An absorbent pad can be disposed between the test strip and capillary tube for spreading-out the fluid being transferred to the test strip. An on-site analyzer such as an optical analyzer and/or an electrochemical analyzer can be mounted in the device for analyzing the fluid. Alternatively, a test strip can be slid through a slot formed in the bottom end of the device so that by passing the device against the skin after an incision has been formed, the test strip will directly contact body fluid emanating from the incision. | 09-02-2010 |

| 20100286564 | TEST MEDIA CASSETTE FOR BODILY FLUID TESTING DEVICE - A bodily fluid sampling device includes a piercing device and a sensor enclosed in a housing. A cassette, which contains test media, is positioned proximal to the sensor so that the sensor is able to analyze a bodily fluid sample collected on the test media. The cassette includes a supply portion from which unused test media is supplied and a storage portion in which contaminated test media is stored after exposure to the bodily fluid. The cassette is adapted to collect a series of bodily fluid samples without requiring disposal of the test media. | 11-11-2010 |

| 20100331731 | BLOOD AND INTERSTITIAL FLUID SAMPLING DEVICE - A device and method for lancing a patient, virtually simultaneously producing and collecting a small fluid sample from a body. The device comprises a blood collection system including a lancing needle, drive mechanism, kneading or vibration mechanism, optional suction system, and sample ejection mechanism. The device is preferably sized to be hand-held in one hand and operable with one hand. The device can optionally contain integral testing or analysis component for receiving the sample and providing testing or analysis indication or readout for the user. In one configuration, the lancing needle may be withdrawn very slightly from the point of maximum penetration to create an opening in which blood can pool before being suctioned through to device. | 12-30-2010 |
| 20110046515 | METHODS AND APPARATUS FOR EXPRESSING BODY FLUID FROM AN INCISION - A sample of a body fluid such as blood or interstitial fluid is obtained from a body by lancing a portion of a user's skin, preferably in an area other than a finger tip, to form an incision. After the needle has been removed from the incision, a force is applied to depress the skin in a manner forming a ring of depressed body tissue in surrounding relationship to the incision, causing the incision to bulge and the sides of the incision to open, whereby body fluid is forced out through the opening of the incision. A stimulator member is mounted to an end of a lancet-carrying housing for applying the force. The stimulator member can be movable relative to the housing, and can be either heated or vibrated to promote movement of the body fluid. | 02-24-2011 |
