Research and Application Evaluation of Accurate Pressure Ulcer Area Measurement Technology Based on AI Grid Intelligent Recognition: A Self-controlled Study

Condition(s) studied

Investigational drug(s) / intervention(s)

AI Grid Image Recognition Measurement: A sterile transparent grid measurement film (single grid area 0.25 cm²) is attached to the pressure ulcer wound. After wound image acquisition, the AI system automatically identifies grids covered by the wound to calculate pressure ulcer wound area.

Traditional Manual Grid Counting Measurement: Based on the same wound photo with transparent grid film, trained clinical staff manually count grids covered by pressure ulcer; grids covered more than half are counted, grids less than half covered are excluded to calculate wound area.

Study summary

The goal of this clinical trial is to learn if AI grid image recognition can measure pressure ulcer wound area accurately and efficiently in adult patients with pressure ulcers. The main questions it aims to answer are:

* Can AI grid image recognition shorten the single measurement time of pressure ulcer wound area?
* Is the wound area measured by AI grid image recognition consistent with the result from traditional manual grid counting? Researchers will compare AI grid image recognition measurement with traditional manual grid counting measurement on the same pressure ulcer wound image collected at a single time point to see if AI recognition achieves comparable accuracy with less operation time.

Participants will:

* Have standardized transparent grid dressing applied on their pressure ulcer wound
* Undergo one-time wound image collection
* Receive sequential wound area measurement using both methods on the captured single wound image

Eligibility

Primary outcome measure(s)
