PROCESS OF MANUFACTURING DRUG DELIVERY SPRAYHEADS

摘要

A process for manufacturing inhalation sprayheads comprising: (a) providing a metallic substrate having a thickness; (b) removing material from the metallic substrate to create one or more holes through the thickness, to create a holed metallic substrate possessing residual material upon said substrate; and (c) exposing the holed metallic substrate to an electrolyte and anodically eroding said residual material from the holed metallic substrate. Devices incorporating such sprayheads for the generation of small droplets are also described.
