Field of invention
The present invention relates to a dressing configured for monitoring skin changes of a subject by use of a computer-implemented method, in particular a multi-layered dressing for covering a wound.
Problem
Wound dressings protect the skin and promote healing, but they also make it difficult to monitor the condition of the underlying tissue. Healthcare professionals often need to remove the dressing to assess wound healing, which can disrupt the healing process, increase the risk of infection, and cause discomfort for the patient.
While transparent dressings allow some visual inspection, they are not suitable for all wound types and can still lead to inconsistent assessments due to variations in lighting, image quality, and observation methods.
Solution
Dermatoo has developed a multi-layered dressing that combines wound protection with digital skin monitoring. The dressing includes an integrated calibration reference that can be detected by an imaging device and analyzed using a computer-assisted method.
By providing a fixed reference point, the system enables standardized image capture over time, allowing healthcare professionals to accurately track skin and wound evolution without having to remove the dressing.
Advantages
- Non-invasive monitoring without removing the dressing, reducing disruption of the healing process
- More accurate and consistent assessments through standardized image calibration.
- Reduced influence of lighting and positioning variations, resulting in more reliable data.
- Support for automated image analysis and advanced imaging techniques, including 3D reconstruction.
- Facilitates remote patient monitoring, enabling healthcare professionals to follow wound progression from a distance.
- Particularly valuable for chronic wounds, where long-term monitoring is essential for effective treatment and prevention of complications
This innovation bridges wound care and digital health, offering a smarter way to monitor healing while improving patient comfort and clinical decision-making.
