This invention belongs to the field of biomedical materials technology, specifically relating to a chitosan hemostatic sponge and its preparation method. This patent addresses the problems of residual acetic acid and side reactions, low strength, and low absorbency caused by cross-linking methods during the preparation of chitosan hemostatic sponges. It innovatively proposes a method for physically cross-linking chitosan hemostatic sponges using hydrogen bonding-electrostatic synergistic superabsorbency based on alcohol-regulated substances. By introducing alcohols to regulate the electrostatic interaction between chitosan amino groups and acetic acid, while simultaneously adjusting the hydrogen bonding interaction between chitosan molecules, and introducing other polymer materials to construct a semi-interpenetrating network, the overall material properties are enhanced. The chitosan hemostatic material prepared by this process, although without the addition of cross-linking agents, still exhibits an insoluble sponge-like structure, good flexibility, and excellent absorbency and hemostatic effect.

The utility model provides a double-pump sprayer, which comprises a bottle body and a sprayer arranged at the top of the bottle body, the sprayer comprises a sprayer body, a liquid suction cavity, a piston cavity and a liquid mixing cavity are symmetrically arranged in the sprayer body, the bottom of the liquid suction cavity is respectively connected with an inner bottle in the bottle body, and the top of the liquid suction cavity is communicated with the piston cavity. One side of the piston cavity is communicated with the liquid mixing cavity, a one-way valve is arranged at the joint of the liquid suction cavity and the piston cavity, and one side of the piston cavity is connected with a handle; when the handle is pressed, the liquid suction cavity can be driven by the piston cavity to convey liquid in the inner bottle in the bottle body to the liquid mixing cavity, and the liquid is mixed and sprayed on the spraying head on one side of the sprayer. According to the double-pump sprayer provided by the utility model, the sprayer body is respectively connected with the two inner bottles in the bottle body through the two groups of liquid suction cavities and the liquid mixing cavity, so that liquid can be mixed at the spray head after the upper liquid is separated, the liquid suction effect is better through the two pump bodies, and the placement orientation of the bottle body in use does not need to be considered; the use is more convenient, and the liquid mixing effect is better.

This utility model discloses a fast-absorbing three-dimensional suspended sanitary napkin, relating to the field of sanitary product technology. It includes a bottom film, a lower core, an upper core, and a top layer. The bottom film includes an adhesive portion and wing portions. The lower core is fixed to the adhesive portion. The wing portions are located around the adhesive portion, and their backs are provided with adhesive for attaching to the user's underwear. Arched elastic sheets parallel to the length of the sanitary napkin are fixed to both sides of the top surface of the lower core. The upper core is fixed to the lower core only at both ends. Elastic cords are fixed to the sides of the upper core, with the other end of the elastic cords fixed to the wing portions. The top layer is fixed to the upper core. This three-dimensional suspended sanitary napkin has excellent anti-leakage and absorbency.

The utility model discloses a waste gas treatment device in rust transforming agent production, which relates to the technical field of waste gas treatment devices, and adopts the technical scheme that the waste gas treatment device comprises a waste gas treatment tower, an exhaust filtering component is arranged in the waste gas treatment tower, and a waste gas treatment component is connected outside the waste gas treatment tower and comprises a fixed disc; the waste gas treatment device in the rust transforming agent production has the beneficial effects that through the design of the water filtering disc in the fixed disc, the absorbent cotton at the top and the water squeezing unit, the absorbent cotton can absorb liquid such as absorption liquid generated in the waste gas treatment process; atomized absorption liquid is prevented from being discharged together when purified waste gas is discharged, waste of the absorption liquid is prevented, a servo motor in the water squeezing unit drives a rotating shaft to rotate, then a connecting shaft, a connecting rod and a water squeezing rolling shaft are driven to rotate, water absorption cotton is squeezed, and the squeezed absorption liquid can be discharged through a water filtering disc and participates in subsequent spraying circulation.
