The invention discloses a filtering and antibacterial device for a hemodialyzer in nephrology, and specifically relates to the field of antibacterial disinfection of medical materials. The device comprises a main body mechanism, an auxiliary regulating mechanism is fixedly installed on the outer wall of the main body mechanism, a fluid channel mechanism is rotatably installed inside the main body mechanism, a plurality of dynamic filtering mechanisms are fixedly installed inside the fluid channel mechanism, and the fluid channel mechanism comprises a plurality of supporting layers, and the plurality of supporting layers are arranged in a superimposed state along the longitudinal center line direction thereof; the invention arranges a plurality of superimposed supporting layers, and arranges a guide tube and a spiral guide plate inside each supporting layer, so that a continuous vortex is formed when the dialysate flows through these spiral structures, thereby increasing the shear force of the fluid, thereby reducing the accumulation of impurities, avoiding the clogging of the filter holes, and reducing the probability of bacteria remaining in the impurities, thereby achieving a highly efficient physical antibacterial effect.

The invention discloses a waterproof, antifouling and antibacterial copolymer protective layer and a preparation method thereof, and relates to the technical field of antifouling coatings. The preparation method at least comprises the following steps: mixing octamethylcyclotetrasiloxane and aminopropyltrimethylsilane for reaction to obtain a side chain amino modified polysiloxane polymer; mixing the side chain amino modified polysiloxane polymer with quaternary ammonium salt-containing epoxy resin, magnetically stirring uniformly, adding tetraethoxysilane and dibutyltin diacetate, and vacuumizing and defoaming to obtain a waterproof, antifouling and antibacterial copolymer coating; the waterproof, antifouling and antibacterial copolymer coating is wiped or sprayed on the dry and clean surface of a base material, and after drying and curing, the waterproof, antifouling and antibacterial copolymer protective layer is obtained. The waterproof, antifouling and antibacterial copolymer protective layer prepared by the invention covers the surface of a base material, is odorless, nontoxic, anti-aging, waterproof, oil-proof, antibacterial, mildew-proof, antifouling and doodling-proof, and has excellent antifouling and self-cleaning functions.

The utility model relates to the technical field of liver disease nursing, and disclose a kind of liver disease nursing infection prevention protection device, comprising: outer protective gloves, the inner wall of outer protective gloves is movably connected with inner protective gloves, the inner wall of outer protective gloves is provided with sub snap, the inner wall of outer protective gloves is bonded with second sub magic paste, the outer wall of inner protective gloves is provided with female snap. The liver disease nursing infection prevention protection device, in the process of using the infection prevention protection device, it can be thickened to prevent puncture by the setting of inner and outer layers, also can improve the puncture prevention effect through the protective structure on the surface of outer protective gloves, avoid the syringe, needle or other sharp objects used by patient in nursing process puncture, so as to avoid the contact between the hand of medical staff and bacteria or germ due to the damage of infection prevention protection device, further improve the protection effect of the infection prevention protection device when using.
