A device for delivering a dose of medicament comprising activated carbon particles to a patient’s rectal cavity has a rectally-insertable cannula. The cannula has a proximal opening, a distal opening and a cavity defined between the proximal and distal openings for containing the medicament. An openable closure spans the proximal opening of the cannula. An actuation means is arranged to drive a volume of fluid, for example water or air, through the cannula cavity to flush the dose of medicament through the distal opening of the cannula.本發明係有關於一用於輸送一包含活性碳顆粒的藥劑之劑量至一患者之直腸腔的具有一可直腸插入的環管之裝置。本環管具有一近端開口、一遠端開口及一用於裝置。本環管具有一近端開口、一遠端開口及一用於裝該藥劑之被界定在位於該近端開口與遠端開口之間的腔。一可開啟的閉合器跨越該環管之近端開口。一致動構件經安排可經由該環管腔驅動一體積之流動(例如水或空氣)以經由該環管之遠端開口沖洗該劑量的藥劑。
