The staged pressure ulcer care model is a specially designed care tool for training nursing staff to identify and handle pressure ulcers at different stages. It mainly addresses the following several issues:

1.  Identification of Different Stages of Pressure Sores  : This model simulates pressure sores of different severity levels, enabling trainees to visually identify the early, middle and late changes of pressure sores, helping them master the staging criteria of pressure sores and providing an accurate basis for subsequent treatment.

2.  Enhance nursing operation skills  : Trainees can master how to effectively care for pressure sores through simulation training, including preventive measures, wound cleaning, dressing changes, and pressure relief techniques, etc., to improve their professional nursing level.

3.  Improve prevention strategies  : This model can help nursing staff understand how to prevent the occurrence of pressure sores through reasonable changes in body position, the use of appropriate mattresses and pads, etc., and reduce complications caused by pressure sores in hospitalized patients.

4.  Improve the quality of patient care  : Through repeated simulation of nursing operations, trainees can more proficiently implement pressure ulcer care in actual work, reduce the aggravation of patients' conditions due to improper care, and enhance the overall quality of care.

In conclusion, the phased pressure ulcer care model provides a systematic training platform, effectively enhancing the skills and response capabilities of nursing staff in pressure ulcer care, ensuring that patients receive timely and accurate care.
