| Popis: | The objective of this research was to design and construction of a compact model of median cubital vein transilluminator to convenient for using and seeing vein more clearly in intravenous injection. This research has adopted the principle of the light absorption of the vein and the principle of electronics. The designed and constructed of the project was composed of 2 main parts: 1) The power supply 9 volt battery and 550 mAh and 2) The light source was composed of 660 nanometer wavelength of light emitting diode, LED driver circuit and IC LM 555 for adjusting the brightness of the light source. The results of functional test found that a compact model of median cubital vein transilluminator can be adjusted the brightness of the light source in the range of 1200–3500 lux and used to examine the vein easier and clearer than the conventional method. The user satisfaction testing result showed that the average satisfaction was 4.22 of 5 points. |
