Page 7: Foreword
Foreword Safety Notes 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. - Page 8 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.) Precocious jaundice If there is a possibility that the newborn infant is suffering from...

Page 17: Inspecting
2) Inspecting ● The instrument can be easily checked to ascertain that it is perform- ing measurement correctly, by using the checker supplied with the Charger unit. ● It is recommended that the instrument be checked once or more each day it is used. - Page 18 Check to confirm that “CHE” is displayed and that the READY lamp is illuminated. Open the checker cover. Reference values Place the measuring probe perpendicular to the check- er, and push it gently until a click is heard. ◆ If the measuring probe is contacted aslant with the checker, place it per- pendicularly and take measurement again.
- Page 19 ◆ The values are acceptable if both the L value and S value are within ±1.0 of the reference values indicated on the checker cover. (The L and S values indicate the hardware characteris- tics.) If the measured value exceeds ±1.0 of the reference value, clean both the S value (measured value of checker and probe, then take mea-...

Page 23: Measurement
Measurement This instrument allows “single measurement”, that handles the result taken from each measurement as the measured val- ue, 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. - Page 24 Release the RESET button while the desired number of average times is displayed. This will record the dis- played number of average times. ◆ n-1: Single measurement Displays the result taken from a single measurement as the measured val- ◆ n-2 to n-5: Average measurement Displays the average of the results taken from two to five measurements as the measured value.

Page 40: Measuring Principle
Measuring Principle The Jaundice Meter JM-103 determines the yellowness of the subcuta- neous 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). The use of this method allows measurement of yellowness of the skin and subcutaneous of a newborn infant with the influences of melanin pig-... - Page 41 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. 2 By calculating the difference in optical densities, the parts that are com- mon to the epidermis and dermis will be deducted, and as a result the difference in optical densities between the two wavelength regions can be obtained for the subcutaneous tissue only.
