Smith & Nephew wanted to build on the success of its dressing-mounted, canister-free negative pressure wound 
therapy (NPWT) system and address the following challenges:

  • Could the device be made smaller and quieter and what battery-powered vacuum pump would enable these performance improvements?
  • Could the required performance improvements be achieved using off-the-shelf pump technology or would a custom design be required?
  • Could a custom design satisfy the commercial considerations of cost-of goods and time-to-market, whilst achieving the necessary improvements in device size and quietness?
