The present invention relates to an antimicrobial dressing band applying an optical pulse capable of stimulating a photochemical reaction by stimulating a pigment, which is a photosensitive material naturally present in a microorganism, with an optical pulse to kill an infecting bacterium. The antimicrobial dressing band to which the light pulse is applied according to the present invention has a hydrogel layer coated with a hydrogel, a circuit board that can be bent or bent, and a battery or wireless power receiver and pulse duration for storing and supplying power to the circuit board. Includes a light emitting device that emits antimicrobial light pulses of 100 μs or less, pulse intervals of 250 μs or less, and light wavelengths between 380 nm and 950 nm, and a microcontroller that adjusts the intervals between pulses and controls light pulse generation and control modules. Characterized in that. According to the antimicrobial dressing band to which the optical pulse is applied, it provides the advantage of suppressing scar generation by hydrogel and increasing the protection effect and treatment effect of deep wound, burn or surgical site while emitting pulsed light. |
