Title:
POROUS DOUBLE MEMBRANE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/209336
Kind Code:
A1
Abstract:
The present invention provides: a porous double membrane comprising a metal-type first porous membrane comprising a first microporous channel and a second porous membrane comprising a second microporous channel, wherein the second porous membrane is a ceramic-type or polymer-type polymer membrane; and a micro-mist generation device comprising a porous double membrane having a micro-mist generation part coupled to the second porous membrane, the device making aerosol of 5 μm or less so as to enable 10% or more of a sprayed drug to arrive at the distal end of the bronchus and the pulmonary alveoli. In addition, the purpose is to provide a method for manufacturing the porous double membrane comprising a metal-type first porous membrane comprising a first microporous channel and a second porous membrane comprising a second microporous channel, wherein the second porous membrane is a ceramic-type or polymer-type porous membrane.
