This invention relates to the field of water-based paint treatment technology, specifically to a water-based paint treatment device and process for wooden furniture production. Technical Problem: In existing technologies, dust on the surface of wooden furniture is blown away using an air gun, causing the dust to fly in the air and easily inhaled by workers, posing a health hazard. Technical Solution: A water-based paint treatment device for wooden furniture production includes a base frame and a lifting component; the lifting component, used to move the table legs upwards, is connected to the middle of the base frame. The water-based paint treatment device for wooden furniture production obtained by the present invention uses the felt fibers to brush away dust from the surface of the table legs. Simultaneously, during movement, the elastic rope sinks into the recesses of the table legs, and the felt fibers on the elastic rope also brush away dust from these recesses. Furthermore, impurities stuck in the recesses are also carried out by the elastic rope, preventing dust residue on the table legs from affecting the subsequent water-based paint spraying quality.

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.
