The aim of the investigation is to evaluate the function of two new device parts to be used in a NPWT system; an on-top suction device intended to transport exudate from the wound and a silicon cover film intended to fixate the wound filler and seal tight to the skin in order to keep a moist environment.

Further study details as provided by Molnlycke Health Care AB:

Primary Outcome Measures:
  • To evaluate the transport of exudate from the wound bed to canister and thus distribute negative pressure in the wound site [ Time Frame: 144 - 288 hours ]

Secondary Outcome Measures:
  • To investigate the practical properties and management of the device, to evaluate the ease of use for the subject and the care giver and to assess any undesirable effects with the suction part [ Time Frame: 144-288 hours ]

Estimated Enrollment: 15
Study Start Date: September 2010
Study Completion Date: May 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: External Suction Interface and a Silicon Film
    Evaluate the function of a new silicon cover film and an on-top suction device to be used in a NPWT system in the treatment of acute and chronic wounds.
