  • Publication number: 20200054893
    Abstract: A light irradiation apparatus includes first and second light sources that emit first light and second light, respectively. The first and the second lights have mutually different wavelengths at timings close to each other, regardless of overlap between the first light and the second light. The first light has a wavelength band for inducing destruction of bacteria by damaging a cell of the bacteria as the first light acts on a photosensitizer present in the bacteria. The second light has a wavelength band for inducing the destruction of the bacteria by changing the structure of a genetic material present in the cell of the bacteria. A dose of the second light source is less than 1/10 of a dose of the first light source.

  • Publication number: 20180050137
    Abstract: A wound treatment method capable of promoting the treatment of a wound is provided. The wound treatment method comprising: placing a foam dressing at a wound site; sealing the wound site by attaching a film dressing to the skin adjacent to the wound site; lowering pressure in a sealed space, which is formed between the film dressing and the wound site, to a target negative pressure level by supplying negative pressure generated by a negative pressure generation unit to the sealed space; maintaining the pressure in the sealed space at the target negative pressure level for a first setting period; stopping the supply of the negative pressure for a second setting period, which follows the first setting period; and injecting a medication into the wound site within the second setting period.
