Abstract

Изобретение относится к кассете (1000) для обработки крови с выполненным в виде жесткой детали (1) корпусом кассеты и пленкой (3), причем пленка (3) соединена с жесткой деталью (1) и, по меньшей мере, участками покрывает жесткую деталь (1). Жесткая деталь (1) имеет по меньшей мере одно дно (226) клапана (288), причем клапан (288) выполнен для занятия помимо первого, открытого, положения клапана (288), в котором дно (226) клапана и расположенный над ним участок пленки (3) не касаются друг друга, при подаче усилия на участок пленки (3) второго, закрытого, положения клапана (288), в котором дно (226) клапана и участок пленки (3) касаются друг друга. Кассета (1000) для обработки крови имеет по меньшей мере одну пружинно- и/или эластично-опирающуюся на жесткую деталь (1) и/или выполненную интегрально с ней проставку, которая расположена для того, чтобы в первом положении оказывать натяжение, усилие или давление на расположенный над дном (226) клапана участок пленки (3), и которая является интегральным элементом пружинного элемента (227a, 227b), соединенного с жесткой деталью (1), или расположена на нем, причем пружинный элемент (227a, 227b) содержит выступы (229a), между которыми и/или у которых образованы дренажные структуры, а также содержит функциональный элемент, представляющий собой опорную решетку (280) гидрофобной мембраны, диск уловителя сгустков и/или обратный клапан.
