본 출원의 예는 제1 플런저, 제2 플런저, 및 제2 플런저와 제1 플런저의 적어도 일부를 수용하도록 구성된 용기를 포함하는 약물 전달 장치를 개시한다. 용기와 제2 플런저는 희석제를 수용하도록 구성된 희석 챔버를 한정한다. 용기는 희석 챔버 개구를 한정한다. 제1 플런저, 용기 및 제2 플런저는 약제학 제제를 수용하도록 구성된 활성제 챔버를 한정한다. 제2 플런저는 활성제 챔버에서 희석 챔버로의 약제학 제제의 유동을 제어하도록 구성된 일방향 밸브를 포함한다. 일방향 밸브는 밸브의 유입구 측에 밸브 임계력을 초과하는 힘이 가해지면 폐쇄 위치에서 개방 위치로 이동하도록 구성된다. 밸브 임계력은 제2 플런저의 해제력과 제1 플런저의 해제력의 합보다 작다. Medication Delivery System and Method Examples of the present application include an infusion device for controlling a medication delivery apparatus to deliver a pharmaceutical preparation to a patient, the infusion device comprising a processor and a memory storing instructions executable by the processor. The instructions include instructions to: determine, a number of infusion steps (h) that are to be performed within a time window, the time window comprising a first time window and a second time window, wherein a first number of infusion steps (h1) are to be performed within the first time window and a second number of infusion steps (h2) are to be performed within the second time window. To determine, for an infusion step of the first number of infusion steps (h1), a first infusion volume, using a cumulative delivery volume function. To determine, for an infusion step of the second number of infusion steps (h2), a second infusion volume, using a dose function. To control the medication delivery apparatus such that the first infusion volume of a fluid is expelled from the medication delivery apparatus during the infusion step of the first number of infusion steps (h1); and the second infusion volume of the fluid is expelled from the medication delivery apparatus during the infusion step of the second number of infusion steps (h2).
