This invention relates to a myocardial repair patch based on multi-material printing, its preparation, and its application, belonging to the field of bio-3D printing and regenerative medicine technology. The invention uses PLCL and GelMA hydrogel loaded with active cardiomyocytes as bio-inks, and introduces gelatin gel as a heat buffer material. An orthogonal network structure is constructed using multi-material bio-3D printing technology to prepare a myocardial repair patch with excellent dynamic adaptability to the myocardial interface and good biocompatibility. The myocardial injury repair patch prepared by this invention achieves a structure-function integrated design through the synergistic effect of the three materials, significantly overcoming the limitations of single materials in terms of mechanical properties, biological function, or thermal compatibility. The mechanical properties of the myocardial injury repair patch prepared by this invention can precisely match those of natural myocardium, while possessing high cell activity, effectively inhibiting fibrosis, improving myocardial function, and achieving true active repair. Furthermore, the process conditions are controllable, demonstrating good translational potential.

The utility model provides a kind of plant-microorganism combined automation biological blanket system suitable for mine slope ecological restoration. The biological blanket system includes the biological blanket main part arranged in the slope surface, further includes water reservoir and rainwater collection pool located in the slope bottom, the biological blanket main part the biological blanket main part includes shaping net layer, ecological layer, micro-irrigation pipe network layer, heat preservation layer and bottom layer net from top to bottom in sequence, the micro-irrigation pipe network layer is the pipe network water spraying layer by multiple micro-irrigation pipes, and the water inlet of micro-irrigation pipe network layer is connected with water reservoir by water inlet pipe;The rainwater collection pool is connected with water reservoir by circulating water pipe and water pump. The utility model can realize synergistic effect between each layer of biological blanket, and through the setting of automatic irrigation system, manpower and material resources are saved, and the problem that plant death caused by not timely irrigation is solved.
