SEM Scanner™

Making Pressure Ulcer Prevention Possible

The SEM Scanner™, is a hand-held, portable, skin tissue assessment device that detects early, pressure-induced tissue damage – including pressure ulcers and Deep Tissue Injuries (DTI)s. It does this by detecting changes in sub-epidermal moisture (SEM), a biophysical marker associated with localized edema and tissue fluid in the inflammatory phase. SEM has been found to indicate tissue damage 3-10 days before visual skin damage or pressure ulcer formation.

The SEM Scanner™ has been successfully used in practice to generate real-time insight to confirm early detection of tissue damage and to target interventions, leading to lower incidence, earlier recovery and lower costs of care.
