In the field of pain relief and treatment there is a need for a device which is able to administer several predetermined doses of an opioid analgesic in a manner which can be done simply and safely by a patient or carer in particular in a manner which minimises the risk of administering too great a dose at any one time.A device (10), for administering a predefined number (N) of predefined volume unit doses (Vu) of an opioid analgesic in liquid form, includes a closed container (12) which contains a predetermined fill volume (Vf) of the opioid analgesic, and a dispenser (14) that is connected to the container (12). The dispenser (14) is operable to administer an individual one volume unit dose (Vu) repeatedly said predefined number of times (N). Both the dispenser (14) is adapted, and the concentration of said opioid analgesic is chosen such that said volume unit dose is in the range 0.05 to 0.15ml.在緩和和治療疼痛的領域中,其需要一種裝置,其能夠以病患或看護員簡單且安全完成的方式來施予數次預定劑量的鴉片類止痛劑;特別是以一種可將在任何時候施予過量之劑量的風險最小化的方式。一種裝置(10),其用於施予預定次數之預定容積單元劑量的液體形式的鴉片類止痛劑,該裝置包括有一個封閉容器(12),其含有該鴉片類止痛劑的預定填充容積(Vf),以及一連接至該容器(12)的分配器(14)。該分配器(14)可被操作,以前述預定次數(N)重複地施予一個別的一容積單元劑量(Vu)。分配器係被調整以及前述的鴉片類止痛劑的濃度係被選擇,使得前述的容積單元劑量係在0.05至0.15毫升的範圍之中。10‧‧‧裝置12‧‧‧容器14‧‧‧分配器15‧‧‧止痛溶液16‧‧‧噴霧頭18‧‧‧裝設主體20‧‧‧泵22‧‧‧汲取管23‧‧‧末端部26‧‧‧噴嘴30‧‧‧噴霧
