This invention provides a graded embolization protection device, belonging to the field of vascular interventional medical device technology. The device includes a delivery guidewire, with multiple protection units fixedly arranged at intervals at the distal end of the guidewire. Each protection unit has a proximal open end and a distal closed end, and each protection unit has a flexible support frame for support at a target location. Multiple open areas are formed on the support frame, and a soft, elastic filter membrane is arranged on the edge of each open area or on the sidewall of the entire support frame to cover the open area. In use, the multiple protection units are axially deployed graded along the target location, with the flexible support frame of each protection unit fully conforming to the inner wall of the blood vessel, and the soft, elastic filter membrane intercepting emboli in the blood flow. This addresses at least the technical problems of existing embolization protection devices, such as poor flexibility due to the high coverage of the rigid support structure, difficulty in adapting to complex vascular morphologies, and poor fit with the vascular wall, leading to embolism escape.

This invention relates to the field of methane catalytic cracking for hydrogen production, and particularly to a glucose-modified activated carbon composite material, its preparation method, and its application. In this invention, activated carbon and glucose are used as the main raw materials, and a glucose-modified activated carbon catalyst is prepared through an impregnation-carbonization process. During carbonization, glucose gradually melts, dehydrates, and cracks to form carbonaceous intermediates. Simultaneously, gases such as H2O, CO, and CO2 are released. These gases activate the pore structure of the activated carbon, promoting the development of micropores and mesopores. Furthermore, the intermediates interact with the activated carbon surface, increasing the content of oxygen-containing functional groups, especially C=O-related functional groups. The resulting fluffy carbon black after glucose carbonization further enhances the initial activity during the methane catalytic cracking reaction and extends the catalytic life.

This invention discloses a fluid flow drag-reducing electrolyzer, comprising an electrolyzer frame and two electrodes, two guide plates, and a diaphragm installed and tightly fitted together within the frame. The electrolyzer frame has an inlet at its bottom and an outlet at its top. The two electrodes are symmetrically distributed on both sides of the diaphragm; each electrode is flattened by rolling. The two guide plates are symmetrically distributed on both sides of the diaphragm and located outside the corresponding electrodes.
