Abstract

A találmány tárgya berendezés (20) áramló közeg célba juttatására,amely változtatható térfogatú mérőtartállyal és a mérőtartálybólkimenethez vezető vezetékkel van ellátva, továbbá első bemenettel(203) és második bemenettel (301), valamint a közegnek a vezeték és amérőtartály közötti áramlását érzékelő áramlásmérővel, továbbá a közegáramlását az első bemenetből (203) a vezetéken át a mérőtartálybamegengedő vagy megakadályozó első szeleppel, valamint másodikszeleppel, továbbá az első és második szelep működését szabályozószabályzóegységgel van kialakítva, és lényege, hogy a többutas szelepelső állásában, a közeg áramlása a második bemenettől (301) akimenetig meg van engedve, és a közeg áramlása a mérőtartálytól akimenetig meg van akadályozva, továbbá a többutas szelep másodikállásában a közeg áramlása a mérőtartálytól a vezetéken át a kimenetigmeg van engedve, valamint a közeg áramlását a második bemenettől (301)a kimenetig meg van akadályozva, továbbá olyan nyomáskülönbségérzékelővel van ellátva, amely a közegnek a második bemenettől (301)kialakuló áramlását érzékelő módon van elrendezve, továbbá eljárásmágneses rezonancia képalkotásra, amelynek során MR képalkotásraalkalmas közeg adagját élő szervezetbe juttatják, valamint MR képetalkotnak az élő szervezet legalább egy olyan részéről, amelybe a közegadagját juttatják, és az adagot a találmány szerinti berendezésseljuttatják az élő szervezetbe. ÓThe subject of the invention is a device (20) for delivering a flowing medium to a target, which is equipped with a measuring tank of variable volume and a line leading to the outlet from the measuring tank, as well as a first inlet (203) and a second inlet (301), as well as a flow meter that detects the flow of the medium between the line and the measuring tank, and it is designed with a first valve that allows or prevents the flow of the medium from the first inlet (203) through the line into the measuring tank, as well as a second valve, and a control unit that regulates the operation of the first and second valves, and its essence is that in the first position of the multi-way valve, the flow of the medium from the second inlet (301) is allowed, and the flow of the medium from the measuring tank to the outlet is blocked, and in the second position of the multi-way valve, the flow of the medium from the measuring tank through the line to the outlet is allowed, and the flow of the medium from the second inlet (301) to the outlet is blocked, furthermore, it is equipped with a pressure difference sensor which is arranged in such a way as to detect the flow of the medium from the second inlet (301), and also for magnetic resonance imaging, during which a dose of a medium suitable for MR imaging is introduced into a living organism, and an MR image is formed of at least one part of the living organism into which the a dose of medium is delivered, and the dose is delivered to the living organism by the device according to the invention.
