AI Technical Summary
Existing skin stretchers are unable to fully stretch the skin when treating large-area ulcer wounds, resulting in poor healing effects and the risk of pain and infection. The effect is particularly poor when the wound is irregular in shape or large in area.
A multi-directional skin stretcher was designed, which uses a center ring and adjustment components. The multi-angle rotation of the support block is achieved through the limit columns and connecting rings on the center ring. Combined with a stretchable fixing strip and skin patch, it provides multi-directional skin fixation and breathability, and the tightness of the fixing strip can be adjusted to adapt to different wound surface requirements.
It achieves multi-directional fixation of large-area, irregular wounds, reduces pain and infection risks, improves wound permeability and healing effects, and reduces patient discomfort.
