Clinical Challenge:

Assessing the inflammatory changes associated with localized tissue edema or pressure induced tissue damage relies on the current standard of patient risk assessments plus subjective visual skin inspections combined with simple tests, such as pitting. Missed, uncertain or incorrect diagnoses are common.

BBI Solution:

BBI's SEM Scanner™, a hand-held, portable device, interrogates the subepidermal layers to detect changes in subepidermal moisture (SEM), a biophysical marker of damaged tissue.

The SEM Scanner™ uses sensor technology to measure tissue electrical capacitance through the application of low amplitude signals from electrodes structures placed on the patient's skin. The electrical capacitance value indicates changes to SEM.

The SEM Scanner™ was developed by one of the world's leading wound care experts for use by clinicians. Advantages of the SEM Scanner™ over the current standard of care include:

  • Objective, evidence-based measurements
  • Non-invasive, rapid results
  • Relative low cost to other diagnostic modalities
  • Applicability across all skin tones
  • Minimal technical skills for operation: most nurses who tested the SEM Scanner were able to accurately use the device with only 10 minutes of training.

Enterprise Format:

BBI is currently developing an enterprise version of the SEM Scanner™ that will capture patient-by-patient and anatomical site-by-site data in real time, wirelessly transmit it in a compliant way to the BBI Databank, rapidly undertake analytics for a select patient or patient population, and report results to the healthcare provider.

The SEM Scanner™ is not available for sale in the United States. For general information on wound care, visit:
