Subcutaneous vein display device based on dual wavelength LED source

Abstract

Purpose: Development of subcutaneous LED vein display device, which is convenient for infusion at night or in dark light and in emergency, to improve the success rate of venipuncture. Method: The adult model uses red light and plant red, and the children model uses orange light and amber LED dual light source design, the lamp beads are connected in axisymmetric form, and automatic sensing is realized through the infrared sensor module. Result: During venipuncture, the infrared sensor module drives the LED to light up when the palm is placed above the display to assist the medical staff in finding blood vessels. Conclusion: The display device can clearly display the position of blood vessels without projecting the subcutaneous blood vessels onto the skin surface in situ, which improves the probability of successful venipuncture once.
