Title:
微細噴霧用多孔性フィルタの製造方法およびこれを用いて製造された多孔性フィルタ
Document Type and Number:
Japanese Patent JP6785888
Kind Code:
B2
Abstract:
The present invention relates to a method for manufacturing a porous filter for fine spraying and a porous filter manufactured by the method. A nickel-palladium alloy material porous filter manufactured according to the present invention exhibits excellent corrosion resistance and metal ion elution mitigating effects and can adjust the size of drug particles, thereby allowing a drug to arrive at the desired site. In addition, a plating liquid having a particular composition in the present invention allows the manufacture of a porous filter with a desired thickness by effectively lowering the stress of palladium (Pd), and thus, in a fine sprayer for treating a respiratory disease, a microporous filter, which is capable of delivering a drug to the vicinity of alveoli while effectively preventing the elution of metal elements due to a drug, apparatus vibration, and the like, and a fine sprayer, which uses the microporous filter, can be manufactured.
