The application discloses a flow-adjustable container, which comprises a bottle body for containing a solvent, a first cover body in interference fit with the bottle body, a second cover body screwed on the first cover body, a first through hole and a flow-adjusting column arranged on the first cover body and communicated with the bottle body, and a second through hole arranged on the second cover body and used for containing the flow-adjusting column; during screwing of the second cover body relative to the first cover body, the flow-adjusting column forms a gap with a variable size with the second through hole or completely blocks the second through hole, and the solvent is led out from the gap; the application has the advantages that the flow size can be adjusted according to requirements, and different use scenarios can be met.

This invention discloses a dressing for treating atopic dermatitis, its preparation method, and its application, relating to the field of medical materials technology. The dressing for treating atopic dermatitis is composed of PH powder and Que@CD nanoparticles. The technical solution provided by this invention utilizes amino-rich ε-polylysine and NHS ester-modified hyaluronic acid for rapid cross-linking via an amidation reaction in a moist environment, forming a three-dimensional gel network encapsulating Que@CD nanoparticles. Utilizing the water solubility of Que@CD, quercetin can be rapidly released to relieve itching. Simultaneously, it exerts anti-inflammatory and antioxidant effects by scavenging excess reactive oxygen species, alleviating oxidative stress, regulating the immune microenvironment, and inhibiting the release of inflammatory factors. Therefore, the dressing proposed in this invention possesses in-situ gelling properties and drug burst release capability, enabling it to closely adhere to irregular skin wounds and comprehensively exert antioxidant, anti-inflammatory, and immunomodulatory effects.
