GENERATION OF THERAPEUTIC MICROFOAM

Изобретението се отнася до терапевтични втвърдяващи се микропени и методи и устройства за произвеждането им, които имат преимущество при произвеждане на инжектируема с консистентен профил пяна, с минимална намеса от лекар, още използвайки големи обемни проценти от диспергируеми в кръв газове, като п...

Zusammenfassung:	Изобретението се отнася до терапевтични втвърдяващи се микропени и методи и устройства за произвеждането им, които имат преимущество при произвеждане на инжектируема с консистентен профил пяна, с минимална намеса от лекар, още използвайки големи обемни проценти от диспергируеми в кръв газове, като по този начин се избягва употребата на потенциално опасни количества от азот. A microfoam for use in sclerotherapy, comprises a physiologically acceptable blood dispersible gas capable of being substantially completely dissolved in or absorbed by blood, wherein the physiologically acceptable blood dispersible gas includes less than 40% v/v nitrogen and comprises at least 50% oxygen or carbon dioxide; and an aqueous sclerosant liquid suitable for use in sclerotherapy, said aqueous sclerosant liquid being aqueous polidocanol or sodium tetradecyl sulphate; wherein the microfoam has a density of from 0.07 to 0.19 g/cm 3 and is capable of being passed down a 21 gauge needle such that 50% or more by number of its gas bubbles of at least 25 µm are of 150 µm diameter or less and at least 95% of these bubbles are of 280 µm diameter or less.
