摘要： A box 14 having a body 13 is used with a transparent flexible bag containing a liquid such as an IV bag. First and second faces 12 are positioned relative to each other. The faces each have therewithin an end or fiber optic port 11 of a respective light path. A light source is optically coupled with the light path of the first face and a spectrometer is optically coupled with the light path of the second face. The light paths are coaxial and are disposed so that the transparent flexible bag is positionable therebetween. The spectrometer is disposed to detect an anomaly in the liquid within the transparent flexible bag, and to annunciate the anomaly to a human user. The box defines a reproducible light path length through the liquid. A caliper 29 having a body 22 may be used in spectrometric analysis of a transparent tube containing a liquid such as a syringe or an IV line. The caliper has finger pads 27 which permit opening the spring-loaded caliper as needed. Rivets 25 provide a pivoting action relative to a pivot structure 21 which can also serve as a distance gauge. Compression spring 24 urges the caliper jaws together at lens locations 26. Lens locations 26 are optically coupled with internal fiber optic lines 28, and thence to external fiber optic connectors 23. A light source is optically coupled with one of the connectors 23 and a spectrometer is optically coupled with the other of the connectors 23.

摘要： A device is provided which passes light of preselected wavelengths through a fluid, gas or vapor to be tested. The light is detected after it has passed through the fluid, gas or vapor. Upon detection, a voltage is created which is proportional in amplitude to the detected light strength for each wavelength of light. These voltages are compared to produce a ratio which represents the condition of the fluid, gas or vapor which is tested or the presence of an analyte of interest. When the ratio is outside of preselected boundaries, control signals are generated which may trigger alarms or otherwise respond to the condition. In a preferred embodiment of the invention, the presence of carbon gases such as carbon monoxide and carbon dioxide is detected in gases or vapors.

摘要： An individualized modeling equation for predicting a patient's blood glucose values is generated as a function of non-invasive spectral scans of a body part and an analysis of blood samples from the patient, and is stored on a central computer. The central computer predicts a blood glucose value for the patient as a function of the individualized modeling equation and a non-invasive spectral scan generated by a remote spectral device. If the spectral scan falls within the range of the modeling equation, the predicted blood glucose level is output to the patient. If the spectral scan falls outside the range of the modeling equation, regeneration of the model is required, and the patient takes a number of noninvasive scans and an invasive blood glucose level determination. The computer regenerates the individualized modeling equation as a function of the set of spectral scans and corresponding blood glucose values.
