Abstract:
Feasibility of developing a new-type micro-fluidic health care device was investigated. Blood test and urinalysis are generally used for the health check. However, to check more simply and easily diseases, utilization of small quantity but easily collected other body fluids such as sputum, sweat, and tears were taken up. These body fluids contain sodium chloride, and it is considered that the content relates to the health conditions. Therefore, the method to easily detect the sodium chloride content was investigated, and it was found that the measurement of spectral transmittance in deep ultra violet light region was effective. It was clarified that the transmittance at wavelengths of 190-200 nm noticeably decreased relating to sodium chloride content and the absorption coefficient well corresponded to the content. Although the relationship between the sodium chloride content and the health condition have to be investigated in detail hereafter, the new device will be feasible for eas
ily monitoring health conditions.
