5. Study Description
Brief Summary
Primary objective
To assess wound healing and granulation tissue formation when using the NPWT system
Secondary objectives
To investigate the pain level at dressing removal
To visually check exudate removal
To investigate the ease of use for the subject and care giver when using the NPWT system
Detailed Description
The investigation is designed as a prospective, open, non-controlled clinical investigation.
Wounds to be treated under this protocol should be Diabetic foot ulcers (DFUs) or post amputation wounds associated with diabetes in hospitalized subjects or subjects treated at home. One ulcer or post amputation wound per subject will be treated for a maximum duration of 4 weeks. All subjects will receive negative pressure treatment with the NPWT system, -120 mm Hg.
In total, 10-15 subjects at two sites will be enrolled provided that they fulfill all the inclusion criteria and none of the exclusion criteria and have signed and dated a written informed consent.
The subjects will be consecutively allocated to a specific subject identification code and the recruitment will be competitive.
The primary variable wound healing and granulation tissue formation will be assessed by digital planimeter, digital photography and visual estimation.
Pain level and subject/investigator convenience will be assessed by convenience surveys.
An evaluable subject is defined as a subject completing the investigation with 4 weeks of treatment, a subject healed before 4 weeks of treatment or if the investigator judge that the wound has adequately responded on NPWT before 4 weeks and that continued treatment can be made with alternative treatment.
