Abstract

Postupak za poboljšanje uredjaja za oslobadjanje leka (10), koji sadrži sud za oslobadjanje pod pritiskom (12), gde taj sud za oslobadjanje pod pritiskom ima merni ventil koji sadrži cilindričnu cevčicu ventila (17), koja koaksijalno klizi unutar elementa ventila (16), a pomenuti element ventila i cilindrična cevčica ventila definišu prstenastu mernu komoru i spoljašnje i unutrašnje prstenaste zaptivače, koji deluju izmedju spoljašnjih i unutrašnjih krajeva elementa ventila (16), zaptivajući prstenastu mernu komoru izmedju njih, naznačen time, što se tim postupkom najmanje jedan ili više delova unutrašnjih površina komponenata mernog ventila, koje dolaze u dodir sa lekom tokom skladištenja ili oslobadjanja, prevlači slojem koji se sastoji od jednog ili više monomera polimerizovanih hladnom plazmom, vezanog najmanje za deo istih, gde pomenuti sloj predstavlja fluorovani ugljovodonik polimerizovan hladnom plazmom. Prijava sadrži još 7 zavisnih patentnih zahteva.A method for improving a drug release device (10) comprising a pressure relief vessel (12), wherein said pressure relief vessel has a measuring valve containing a cylindrical valve tube (17) which coaxially slides inside the valve element (16) , and said valve element and cylindrical valve tube define the annular measuring chamber and the outer and inner annular seals acting between the outer and inner ends of the valve member (16), sealing the annular measuring chamber between them, by at least one or multiple portions of the inner surfaces of the components of the metering valve, which come in contact with the drug during storage or release, are coated with a layer consisting of one or more monomers polymerized by cold plasma bonded to at least a portion thereof, wherein said layer is a fluorinated hydrocarbon polymerised by cold plasma. The application contains 7 more dependent claims.
