The invention discloses a multifunctional bionic coating for magnesium-base medical materials and devices as well as a preparation method and application of the multifunctional bionic coating. The preparation method of the coating comprises the following steps: 1) preparation of an alkaline catalyst-organic solvent: dissolving and mixing an alkaline catalyst in an organic solvent; 2) preparation of a dopamine monomer solution: dissolving and mixing a dopamine monomer in the alkaline catalyst-organic solvent; and 3) preparation of a coating: immersing a magnesium-base material or a device in the dopamine monomer solution, and promoting in-situ growth through a self-polymerization reaction so as to obtain a required polydopamine coating. The method disclosed by the invention can be used for solving the problem of coating defect due to easy corrosion of the magnesium base in the preparation of the polydopamine coating in a water solution environment; and the prepared coating has the following characteristics and functions: the coating is dense and complete and is capable of significantly improving the corrosion resistance of the magnesium base and delaying degradation, the coating is capable of significantly improving the biocompatibility of magnesium-base materials and devices, and the coating, as an intermediate layer, is capable of achieving secondary functionalization and multi-functionalization; and the coating is simple and convenient in operation process, strong in binding force with a substrate and controllable in thickness.

The invention discloses a collision detection method, device and a network device of a dual-master device in a thermal staking system, and provides a dual-master device detection technology applicable to a thermal stacking system composed of a two-layer device and a three-layer device and meeting the network compatible requirement at the same time, and thus the availability of the dual-master device detection technology is improved. The method comprises the following steps: an original master device of the thermal staking system receives an LLDP (link layer discovery protocol) massage sent by an opposite end detection port through a detection port arranged in advance, wherein the LLDP massage carries a device identification of a master device of the thermal stacking system of the opposite end detection port at present; and the original master device determines whether the device identification carried in the LLDP massage received currently and the device identification carried in the LLDP massage received last time are identical, if so, the dual-master collision does not exist, and if not, the dual-master collision exists.

The invention relates to a preparation method of a medical rubber stopper, which comprises the steps as follows: a rubber stopper is immersed into alkaline aqueous solution; the rubber stopper treated with the alkaline aqueous solution is immersed into acid aqueous solution for neutralization; the rubber stopper neutralized with the acid aqueous solution is rinsed with purified water or water forinjection and siliconized with silicone oil; the siliconized rubber stopper is dried at 115-130 DEG C; and the medical rubber stopper meeting the requirement of compatibility of particular drugs is obtained. The preparation method of the medical rubber stopper has simple process and realizes industrialization easily. High-performance medical rubber stoppers treated by the method do not affect thesealing performance of the original halogenated butyl rubber stopper, and can meet the requirements of Standard YBB00042005 and / or Standard YBB00052005 issued by the State Food and Drug Administration and the requirement of compatibility of particular drugs.
