This invention relates to the field of medical monitoring equipment technology, specifically disclosing a magnetically positioned flap monitoring device, system, and method. The invention achieves a stable fit between the medical adhesive layer on the bottom surface of the base dressing layer and the skin surface of the flap area. Utilizing the magnetic attraction between the first magnet group on the magnetic docking ring and the second magnet group on the flexible sensing patch, a modular sensing connection architecture that can be repeatedly assembled and disassembled is constructed. This solves the problems of traditional adhesive tape or suture fixation methods, which are prone to probe slippage due to skin sweating or changes in body position, causing monitoring interruptions. It also addresses the lack of a unified spatial positioning benchmark in multi-probe collaborative layouts, making it difficult to achieve systematic mapping of blood perfusion in the flap area. This improves the continuity and stability of postoperative flap monitoring and enhances the ability of the optical sensor array to capture information on the overall spatial distribution of blood perfusion in the flap.
