In a world first, Ushio Inc. and the National University Hospital of Singapore have succeeded in bacterial disinfection of pressure ulcer injuries using 222nm ultraviolet light that is harmless to the human body.

We’re thrilled to announce that Ushio Inc. and the plastic surgery group led by Professor T.C Lim, Head & Senior Consultant, Division of Plastic, Reconstructive & Aesthetic Surgery at the University Hospital of Singapore, have succeeded in disinfecting wounds of patients using a 222nm UV irradiation device manufactured by USHIO that does not cause adverse effects on the human body.

The breakthrough truly signifies a game changer for the healthcare industry in terms of potentially lifesaving applications which are created from the development of the new technology.

Potential applications include but are not limited to:

  • The treatment of infected chronic wounds
  • Disinfection of surgical sites during surgery
  • Minimising aerial and contact infections by H1N1 (Bird Flu), SARS-CoV, MERS-CoV, Dengue Fever and the Ebola Virus
  • Ultraviolet hand disinfection devices
  • Introduction of sterilising capability into hand-dryers, etc.
  • Spore fungus and norovirus sterilisation

The new device is realised by narrow band spectrum technology which penetrates and kills bacteria with 222nm radiation using the USHIO KrCI Excimer lamp but is absorbed by the stratum corneum so that it does not reach human cell nuclei at the cellular level or epidermal cells at the tissue level. Furthermore, this technology dramatically reduces biological damage to human cells in comparison with convention UV rays, whilst still providing the disinfecting effect of conventional UV lamps.

Whilst this technology is not yet available for mainstream sales, click here to view the current range of UV Excimer solutions.
