    摘要: The present invention relates to a method of building instrument variation tolerance into calibration algorithms for spectroscopic devices for chemical composition analysis with spectroscopic methods. The method of the present invention is particularly suitable for blood glucose, cholesterol and other chemical components prediction based on near-infrared spectrophotometry measurements. A method includes developing a calibration algorithm on a first instrument; applying the calibration algorithm to a second instrument; calibrating the second instrument and adjusting the calibration algorithm to account for differences between the first instrument and the second instrument; and repeating the step of applying (above) in respect of (n) further instruments to provide a calibration algorithm which may then be used on other instruments. Methods are also provided that develop calibration algorithms by adding instrument variations, based on mathematical manipulation, of the spectral data collected on calibration instruments.

    摘要: A finger receptor is used with a non-invasive monitoring device to determine non-invasively the concentration of known constituents in blood or tissue. The receptor has a channel for receiving a finger of a user. The channel has a light entrance and a light exit so that light can be passed from a light source through a finger located in the channel in a direction generally normal to the finger. Extraneous light is excluded and the finger is held in position by a spring-mounted roller. The receptor has sensing means to determine when a finger has been properly positioned in the channel. Previous devices are not capable of achieving repeatable results to a sufficient degree to replace invasive methods of testing.

    摘要: A method and apparatus for use in respect of samples which are assessed for quality prior to testing in a clinical analyzer. The method and apparatus identify parameters such as gel level and height of fluid above the gel in blood samples, where appropriate, for the purposes of positioning the specimen for determination of interferents. Such interferents include hemoglobin (Hb), total bilirubin and lipids. These interferents are determined by measurement of absorption of different wavelengths of light in serum or plasma, or other specimens, which are then compared with values obtained through calibration using reference measurements for the respective interferents in serum or plasma or other type of specimen. Determinations of temperature of the specimen, as well as specimen type, for example whether the specimen is urine or plasma or serum, may also be carried out.

    摘要: A medical radio telemetry system has a plurality of telemeters with one telemeter being located on each patient. Each telemeter is connected to the patient to collect data such as temperature, heart rate, pacer rate, respiration rate, brain activity level and blood pressure level. Each telemeter has a patient locator system that functions in conjunction with one or more room locator transmitters. The room locator transmitters are spaced in the rooms or area where the location of a patient is being monitored. A signal from the patient locator transmitter is passed to the patient telemeter. All signals received by the patient telemeter are transmitted to an antenna system that is connected to a receiver. Preferably, there is more than one antenna system with means for switching between the systems to obtain the best signal. Each telemeter has up to six channels so that six separate signals can be sent to the receiver simultaneously. The receiver is connected to a display means for the signals.
