Abstract: The present invention relates to the technical field of medical devices, in particular to a drug coating, a drug-coated balloon and a preparation method thereof. The drug coating comprises a drug active coating and a positively-charged hydrophobic modified layer which are sequentially attached to the surface of a substrate. By providing the positively charged hydrophobic modified layer comprising the positively-charged modified substance and the hydrophobic substance, the entire surface of the drug coating is given positive electric charge and hydrophobic property. Such positive electric charge characteristics make the drug coating can be strongly combined with the negatively-charged inner wall of blood vessels, so that the drug coating can be permanently adsorbed on the inner wall of blood vessels. The combination of positive electric charge characteristics and hydrophobic property can effectively resist the influence of blood flow on the erosion of drug coating during transportation.

Abstract: Provided are a power supply assembly of an aerosol-generation apparatus and an e-cigarette. The power supply assembly includes: a housing, an air inlet being provided on the housing: a support arranged in the housing and including first and second mounting portion, and a circuit structure being arranged on the support: a main board assembly and a power supply that are arranged on the second mounting portion; an electrode terminal arranged on the first mounting portion and electrically connected to the circuit stricture and a vaporizer respectively a first sealing member arranged on the support and abutting against an inner wall surface of the housing: and a second sealing member arranged on an end of the first mounting portion away from the first sealing member and abutting against the inner wall surface of the housing. The first sealing member and the second sealing member define an air-inlet region in the housing.
