Negative Pressure Wound Therapy Using a New Pressure Monitoring Device for Wound Treatment: Results of an Animal Model

The WPMD accurately and sensitively detected real-time pressure changes on wound surfaces under different preset negative pressure values (-125 mm Hg and -75 mm Hg). Furthermore, NPWT significantly accelerated wound healing in the rat model, and the healing rates were better in the -75 mm Hg group than in the -125 mm Hg group at day 5 and day 7. These results underscore the potential application of the WPMD in investigating the relationship between negative pressure values and wound healing rates across various wound types during treatment.
