    Abstract: A quick registering thermometer (34) utilizing a sensor (50) that has electrical resistance varying with temperature and that is located at the tip (37) of a probe (36), the sensor (50) having a relatively small thermal mass and a short thermal time constant. Within seconds of contact with the patient, the circuitry (40) communicating with the sensor (50) determines the rate of change in resistance of the sensor (50) and, in turn, the temperature that the sensor (50) would reach if allowed the length of time it would need to reach equilibrium with the contact surface of the patient. Based on the equilibrium temperature determined for the surface of the patient, the circuitry (40) calculates and registers the core body temperature.

    Abstract: This invention is a method and apparatus for monitoring glucose, ethyl alcohol, and other blood constituents in a noninvasive manner. Long wavelength infrared energy emitted by the person as heat is monitored and the infrared absorption of particular constituents in the blood is measured (114) at characteristic infrared absorption wavelengths (110) for those constituents. The measurements are preferably synchronized (124) with systole and diastole of the cardiac cycle so that the signal contribution caused by veins and tissues may be cancelled when a ratio of the detected signals is taken. If no synchronization is provided, the spectrophotometer may measure the arterial, venous, and tissue constituent concentrations simultaneously. The internal "blackbody" energy level of an infrared emissions source such as a vascularized appendage is measured (300) and used to compensate temperature dependent effects in the concentration calculation. The internal energy level ratio is ratioed to the actual measured energy.

    Abstract: A procedure for verifying the accuracy of a non-invasive blood glucose measurement instrument (10) utilizes in vitro or invasive measurement instruments (100), the accuracy of which is independently verifiable. Several glucose readings are taken with each instrument at approximately the same times. The measurement data from the in vitro instrument (100) is transferred to the non-invasive instrument (10) where it is compared to the data regarding the non-invasive measurements. If the difference between the measurements of the respective instruments is within a preset range, the non-invasive instrument is permitted to be used for an additional period of time. However, if the difference is beyond an acceptable limit, then the non-invasive instrument is prevented from taking any additional measurements and must be serviced or repaired.
