[. . . ] JAUNDICE METER JM-103 Captures Data Instantly, Compact, Easy to Operate, Designed for All Skin Colors Actual Size Direct reading for total serum bilirubin in mg/dL or micro mol/L Premature baby measurable (more than 1000g) Skin color affects measurment much less than in previous models. [. . . ] The Diffuser panel light is then scattered and absorbed in the skin repeatedly, and finally Sensor for long optical path returns to the glass fiber (sensor 2-wavelength photodiode side). Of the light that returns to the fiber, the part scattered from Diffuser panel shallow areas of the subcutaneous Long optical path tissue passes through the inner Light-emitting path core (short optical path) of the fiber Glass fiber Short optical path while the part scattered from deep areas of the subcutaneous tissue passes through the outer core (long optical path), and then they reach their corresponding photodiode. Xenon lamp Fig. 1 By calculating the difference in optical densities, the parts that are common 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. Since the optical density difference shows a linear correlation with serum bilirubin concentration, it is converted to serum bilirubin con-centration and indicated digitally. Short optical path Long optical path Epidermis Dermis Subcutaneous tissue Short optical path Long optical path Mature baby Premature baby Fig. 2 Main Specifications Measuring method: Determines yellowness of subcutaneous tis-sue by using two optical paths to measure optical density difference at two wavelengths 0. 0~25. 0 mg/dL or 0~425 µmol/L ±1. 5 mg/dL or ±25. 5µmol/L LCD(back light) Figure: 3 figures Unit: mg/dL, µmol/L(changeable) Battery mark Ready lamp: green LED lit Pulse xenon arc lamp 150, 000 measurements Silicon photodiodes Special Ni-MH battery Internally powered instrument, BF type At least 400 measurements when fully charged 10 to 40°C, relative humidity 30 to 95% or less with no condensation -10 to 50°C, relative humidity 30 to 95% or less with no condensation 48mm(W)×154mm(H)×32mm(D) 150g(including Ni-MH battery) Averaging function Charger Unit (with a built-in checker) AC Adapter, Strap, Soft Case Charger Unit (with a built-in checker) M easuring range: A ccuracy (): D isplay: Ligh t source: Ligh t source life: S ensors: P ower source: P rotection type and le vel: P ossible number of M easurements: Operating temperature/ humidity range: S torage temperature/ humidit y range: D imensions: W eight: O ther function: Standard accessories: SAFETY PRECAUTIONS For correct use and for your safety, be sure to read the instruction manual before using the instrument. · Always connect the instrument to the specified power supply voltage.
