The Novel Digital Therapeutics Sensor and Algorithm for Pressure Ulcer Care Based on Tissue Impedance

Area of Science:

• Biomedical Engineering
• Medical Diagnostics
• Wound Care Technology

Background:

• Current pressure ulcer diagnosis and treatment methods, such as visual inspection and rejuvenation, present challenges in effective management.
• The need for accurate, non-invasive diagnostic tools and efficient therapeutic devices for pressure ulcers is critical.

Purpose of the Study:

• To develop and validate a novel biophotonic sensor for accurate pressure ulcer diagnosis.
• To create and assess the efficacy of a pressure ulcer care device (PUCD) for treatment and immune cell modulation.

Main Methods:

• Development of a biophotonic sensor integrated into a pressure ulcer care device (PUCD).
• Validation of the diagnostic algorithm's accuracy using clinical data.
• Evaluation of the PUCD's therapeutic effect on pressure ulcer-induced mice, including immune cell analysis.

Main Results:

• The pressure ulcer diagnosis algorithm achieved an accuracy of 91%.
• The PUCD demonstrated an 85% reduction in immune cells in treated mice.
• Analysis of immune cell nuclear shape confirmed the PUCD's effectiveness in modulating the inflammatory response.

Conclusions:

• The developed biophotonic sensor and PUCD offer a promising integrated solution for pressure ulcer diagnosis and treatment.
• The PUCD's ability to modulate immune cell response suggests its potential as an effective recovery method for pressure ulcers.
