The invention relates to an anti-colorectal adhesion monitoring patch and a monitoring system thereof, which are characterized in that the anti-colorectal adhesion monitoring patch and an in-vitro wireless monitoring terminal which are wirelessly connected are arranged, the anti-colorectal adhesion monitoring patch is of a three-layer membrane structure which is tightly connected, and the three-layer membrane structure sequentially comprises an anti-adhesion layer, a monitoring layer and a supporting layer from outside to inside; the anti-adhesion layer is used for physically blocking other tissues of a human body, such as an intestinal canal and a peritoneum, from being in direct contact with a surgical wound surface; the monitoring layer is used for capturing a deformation signal generated when the membrane body is pulled when tissues in the abdominal cavity are adhered in real time; the supporting layer is used for fixing the structures of the anti-adhesion layer and the monitoring layer; and the in-vitro wireless monitoring terminal is used for monitoring the abdominal cavity adhesion condition of the target person in real time according to the electric signal from the monitoring layer, and early warning in time when the abdominal cavity adhesion condition of the target person is monitored. The device has the effect that the effective combination of the biodegradable anti-adhesion function and the non-invasive adhesion monitoring function can be realized.

The invention discloses injectable conductive anti-adhesion hydrogel and a preparation method and application thereof, hydrogel raw materials comprise a phytic acid doped hydrazide group-containing gelatin-based conductive polymer, an aldehyde group-containing amphiphilic block copolymer and a catalyst, and the three raw materials are mixed under body temperature and physiological conditions and then subjected to in-situ crosslinking to form the hydrogel. The hydrogel has the characteristics of rapid gelling, self-healing, injectability, electric conduction, oxidation resistance and the like. In-vivo experiments show that the hydrogel can significantly inhibit postoperative abdominal adhesion, reduce inflammatory response and remove active oxygen; meanwhile, the hydrogel can promote collagen deposition, angiogenesis and muscle regeneration, is suitable for abdominal wall defect repair and postoperative adhesion prevention, and solves the problem that an existing material is difficult to give consideration to adhesion prevention and repair promotion.
