The application discloses a silk fiber-based anti-bedsores decompression pad and a preparation method thereof, which comprises a fabric layer in a concave shape, an aerogel layer and a fiber layer are arranged in the fabric layer from bottom to top, the total height of the aerogel layer and the fiber layer after being stacked is equal to the depth of the fabric layer, the fiber layer is prepared from drug-loaded hydrophobically modified sodium alginate fiber, and the aerogel layer is prepared from degummed silk-sodium alginate composite aerogel with a three-dimensional porous structure. The decompression pad has antibacterial and healing promotion effects, the silk fiber enhances the physical and mechanical properties of the aerogel layer, can greatly reduce external pressure, has excellent air permeation effect due to the through-hole structure in the interior, can fully and quickly absorb wound exudates, the sodium alginate-based material also provides a suitable microenvironment for cell growth, accelerates wound healing, and is suitable for the prevention and treatment of bedsores of patients who need to be in bed for a long time.

The utility model relates to fireproof roller shutter door technical field discloses a kind of self-cleaning noise reduction mechanism of fireproof roller shutter door guide rail, including the limiting noise reduction piece being installed on the inner wall of fireproof roller shutter door guide rail notch and the cleaning piece for the self-cleaning of limiting noise reduction piece, limiting noise reduction piece and roller shutter side end contact, cleaning piece and limiting noise reduction piece contact. By setting the limiting noise reduction piece of roller shutter side end contact, the running track of roller shutter can be limited, and the friction noise between roller shutter and guide rail is reduced, by setting the contact of cleaning piece and limiting noise reduction piece, dust and sundries on the surface of limiting noise reduction piece can be automatically removed, to avoid pollutants affecting its performance, realize the self-cleaning and noise reduction double function of fireproof roller shutter door guide rail, improve the running stability and service life of roller shutter door.
