| 20110120206 | METHODS OF CALIBRATING A SENSOR IN A PATIENT MONITORING SYSTEM - The present application discloses a number of methods of calibrating a sensor for measuring an analyte in a patient monitoring system. In a first embodiment, the method comprises calculating a sensor drift; calibrating the sensor using at least one calibration fluid; and periodically updating the sensor calibration based on the sensor drift calculation. In a second embodiment, the system comprises means for adjusting a gas concentration in a fluid, and the method comprises providing a calibration fluid; setting the analyte concentration in the first fluid to a first concentration with said adjusting means; measuring the first analyte concentration with the sensor; setting the analyte concentration in the first fluid to a second concentration with said adjusting means; measuring the second analyte concentration with the sensor; and determining the calibration coefficients for the sensor from the measured first analyte concentration and the measured second analyte concentration. In a third embodiment, the method comprises exposing the sensor to a first fluid comprising a first unknown concentration of the analyte; measuring the first unknown analyte concentration with the sensor; determining the first unknown analyte concentration with an analyser external to the patient monitoring system; providing the sensor with the determined first analyte concentration, and determining the calibration coefficients for the sensor from the measured first unknown analyte concentration and the analyte concentration determined by the analyser. At least some of the above embodiments ensure that the period between recalibrations of the sensor is extended, thus reducing the number of disruptions to the sensor monitoring process. | 05-26-2011 |

| 20100163431 | Sensor - This invention relates to a sensor for detecting an analyte in the presence of at least one interferent in a fluid sample. The sensor comprises a substrate, a channel disposed on the substrate, at least one transducer disposed in the channel, and a filter for selectively absorbing the analyte in preference to the at least one interferent. The filter is arranged in the channel remotely from the at least one transducer and the channel defines a flow path for the fluid sample such that the fluid sample contacts a first transducer to generate a first signal, followed by the filter, followed by the first transducer or a second transducer to generate a second signal. | 07-01-2010 |

| 20090149607 | SYNTHETIC RECEPTOR - A polymer capable of selectively binding propofol is prepared from one or more suitable monomers (e.g. N,N-diethylaminoethyl methacrylate) and a cross-linker. It may be a molecularly imprinted polymer. An element ( | 06-11-2009 |
| 20100075432 | SENSOR - This invention relates to a sensor and in particular to a sensor for the detection of biologically important species. Specifically, the invention provides a sensor for detecting an analyte in a sample. The sensor comprises a transducer and a receptor layer in electrical communication with the transducer, wherein the receptor layer comprises a receptor material and a dispersed electrically conductive material | 03-25-2010 |
| 20100173421 | SENSOR - This invention relates to a sensor and in particular to a sensor for the detection of biologically important species. Specifically, the invention provides a method for detecting an analyte in the presence of at least one interferent in a sample. The method comprises the steps of providing a sensor having a transducer and a receptor layer in communication with the transducer, in which the receptor layer comprises a material for absorbing the analyte; exposing the receptor layer to the sample; treating the receptor layer to remove selectively the at least one interferent; and measuring the signal from the transducer. The treatment step is performed by applying a change in potential, a change in pH or a change in temperature to the receptor layer, by washing the receptor layer, by irradiating the receptor layer, or a combination thereof. | 07-08-2010 |
