A compact battery-operated fingertip apparatus (so called "pulse oximeter") combining an electronic processor, a pair of light emitting diodes (LED), a photo diode and an LED display (offering various display modes) in one unit. It is also equipped with a low battery indicator, an alarm function in case of high or low pulse rate or blood oxygen, and a "clip in" attachment to the finger.It is used as a non-invasive method of monitoring a person's oxygen saturation and for measuring a pulse by means of optical radiation. After attaching to a person's finger, the LED pass two different wavelengths of light through the finger to a photo diode. It measures the changing absorbance at each of the wavelengths and subsequently determines/calculates the oxygen saturation and heart rate.It can be used in professional medical practice and in research, sport, business etc. (for example, oxygen chambers, extreme mountaineering in low oxygen atmosphere, deep-sea diving; by pilots, firefighters, astronauts etc.).See image. | 90181910 | Classification is determined by general rules 1 and 6 for the interpretation of the Combined Nomenclature and by the wording of CN codes 9018, 901819 and 90181910.The apparatus falls under the scope of heading 9018 which covers a very wide range of instruments and appliances which, in the vast majority of cases, are used only in professional practice to prevent or treat an illness or to operate, etc. The instruments and appliances classified here may be equipped with optical devices; they may also make use of electricity (see also the Harmonised System Explanatory Notes to heading 9018). While this kind of apparatus can be used by non-professionals, it is of a kind used for medical purposes as it provides information concerning "vital body functions" that may need to be further analysed by professionals.Classification under heading 9027 as instruments and apparatus for physical or chemical analysis using optical radiation is consequently excluded.It is therefore to be classified under CN code 90181910 as instruments and apparatus used in medical science, monitoring apparatus for simultaneous monitoring of two or more parameters. |
