Abstract
This invention belongs to the field of gradient controlled-release stent mold technology, and discloses a gradient controlled-release stent mold for seed treatment agents. The mold includes a base with a hollow center and a conical top; a multi-layer barrier sheet assembly arranged concentrically within the base, comprising at least three types of metal mesh sheets with different porosities and biodegradable spacers between the mesh sheets; and a contoured support plate detachably mounted to the bottom of the base. A spiral guide plate is installed on the inner wall of the top cavity of the base, with the spiral angle of the guide plate gradually increasing along the fluid direction. A snap-fit groove is provided at the bottom of the base. This invention, through the synergistic effect of the multi-layer mesh pore size gradient design and the biodegradable spacers, enables the layered release of the agent as needed, solving the problems of single release rate, agent waste, or insufficient efficacy in traditional coating technologies, and significantly improving utilization.
