Safety Notes Foreword Foreword This instrument is designed for estimating total serum bilirubin concentration, that is necessary for the screening of jaundice in newborn infants. It must be used for newborn infants only. Never press the measuring probe when it is directed to the eyes. Doing so may cause eye damage. To prevent kernicterus in newborn infants, it is very important to detect jaundice in its early stages.
Foreword Hemolytic jaundice Normally, in the case of hemolytic jaundice that appears before the age of three days, measurement of total serum bilirubin concentration must also be taken. (The correlation between the measured value taken by the instrument and total serum bilirubin concentration drops substantially due to physiologic factors.

Preparation 1 “CHE” will appear on the display, but leave the RESET button held down. u The unit of measurement will be switched when approximately 15 seconds have elapsed. u If the RESET button is released while “CHE” is displayed on the display, the check mode will be activated.
3 Check that the unit of measurement has been switched. u “CHE” will disappear and the unit of measurement is displayed. Preparation 4 When switching the unit of measurement, the one for the previous measurement will not be displayed. The newly selected unit of measurement is displayed. (An example of switching from “mg/dL” to “μmol/L” is shown above.) Release the RESET button. u The READY lamp will light up, indicating that the instrument is ready for measurement.
Measurement Preparation This instrument allows “single measurement”, that handles the result taken from each measurement as the measured value, and “average measurement” that handles the average of the results taken from two to five measurements as the measured value. The number of measurements to be taken must be set according to the measuring point and measurement state.
3 Measurement 22 Release the RESET button while the desired number of average times is displayed. This will record the displayed number of average times. u n-1: Single measurement Displays the result taken from a single measurement as the measured value. u n-2 to n-5: Average measurement Displays the average of the results taken from two to five measurements as the measured value. If “2” to “5” is selected, “AVG” will appear in the upper left corner of the display.
Measuring Procedure Removing from Charger Remove the main body from the charger. 2 Clean the measuring probe with medicinal alcohol. 3 Set the POWER switch to ON. Measurement 1 u The READY lamp will light up after a few seconds, indicating that the instrument is ready for measurement. u If the instrument is not operated for more than 60 seconds, the back-light on the display and READY lamp will go out. In this case, press the RESET button to ready the instrument for measurement.
Single Measurement Make sure that single measurement is selected. (For the method of setting the number of measurements to be taken, refer to “Setting the Number of Average Measurements” on page 21.) 4 Measurement 5 While “n-1” is displayed, make sure that the READY lamp is lit. Place the measuring probe against the point to be measured, and push it gently until a click is heard. u The instrument’s xenon lamp will flash momentarily, and the measured value will appear on the display.

To take another measurement, press the RESET button and continue from step 4. Average Measurement (example using five times as the average) Make sure that average measurement is selected. 4 5 Check to ensure that the READY lamp is illuminated once “n-5” has been displayed.
5 -2 While making sure that the READY lamp is lit, repeat the remaining number of measurements. Measurement u When the remaining number of measurements is completed, the average of the measured values will be displayed. u If the instrument is left without performing the remaining measurements, no measured value will be displayed, the instrument will no longer be ready for measurement, and the average measurement will be cancelled.
Regarding the measurement accuracy • If the measured value is outside the measurement range (25.1 to 30.0 mg/dL, 426 to 510 μ mol/L), it will blink. This means that the value is outside the guaranteed measurement accuracy range. Regarding outside the display range • If the measured value is outside the display range (i.e. exceeds 30.1 mg/dL, 511 μ mol/L), “-0-” will be displayed.
Storing the Instrument Measurement 7 Set the POWER switch to OFF. 8 Clean the measuring probe with medicinal alcohol. 9 Place the instrument on the Charger unit. u When the instrument is not in use, keep it placed on the Charger unit.

Measuring Principle The Jaundice Meter JM-103 determines the yellowness of the subcutaneous tissue of a newborn infant by measuring the difference in optical densities for light in the blue (450 nm) and green (550 nm) wavelength regions. The measuring probe has two optical paths (see Fig. 1).
tissue passes through the outer core (long optical path), and then they reach their corresponding photodiode. Short optical path Long optical path Short optical path Epidermis Long optical path Dermis Subcutaneous tissue Mature baby Premature baby Fig.
Clinical Test Result Report To verify serviceability of the JM-103 Jaundice Meter, the correlation between values measured by the instrument and the serum bilirubin was measured at three domestic hospital facilities. The standard deviation ( σ ) from the regression line obtained at that time was ±1.24. ❋: T he standard deviation ( σ ) being ±1.24 means that approximately 68% of the data taken from measurements performed on a living body is within this range.
