A drug injection device according to the present invention comprises: a drug injector for electrochemically driving an electroosmotic pump so as to suction a drug from a drug storage and discharging the suctioned drug to an object to be injected ; and a control unit for outputting, to the drug injector, a control signal corresponding to a dose-based injection sequence for immediately driving the electroosmotic pump in an injection mode, wherein the dose-based injection sequence includes one or more pulse blocks that define a voltage pulse or a current pulse to be applied to the electroosmotic pump, each of the pulse blocks defines a pair of pulse signals including a forward pulse and a reverse pulse, which are applied to the electroosmotic pump so as to alternately generate negative pressure and positive pressure, and the electroosmotic pump alternately generates the negative pressure and the positive pressure for each pulse block so as to suction and discharge the drug. Dispositif d'injection de médicament selon la présente invention comprenant : un dispositif d'injection de médicament qui entraîne électrochimiquement une pompe électro-osmotique, de façon à aspirer un médicament à partir d'une unité de stockage de médicament, et administre le médicament aspiré à un patient devant recevoir une injection ; et une unité de commande qui délivre, au dispositif d'injection de médicament, un signal de commande correspondant à une séquence d'injection basée sur la dose pour entraîner immédiatement la pompe électro-osmotique dans un mode d'injection, la séquence d'injection basée sur la dose comprenant au moins un bloc d'impulsions qui définit une impulsion de tension ou une impulsion de courant à appliquer à la pompe électro-osmotique, chacun des blocs d'impulsions définissant une paire de signaux d'impulsion comprenant une impulsion aller et une impulsion retour, qui sont appliquées à la pompe électro-osmotique de façon à générer en alternance une pression négative et une pression positive et la pompe électro-osmotique générant en alternance la pression négative et la pression positive pour chaque bloc d'impulsions de façon à aspirer et à administrer le médicament. 본 발명에 따른 약물 주입 장치는, 전기화학적으로 전기삼투펌프를 구동하여 약물 저장고로부터 약물을 흡입하고, 흡입된 약물을 주입 대상으로 토출하는 약물 주입기; 및 상기 전기삼투펌프를 즉시 주입 모드로 구동시키는 양 기반 주입 시퀀스에 대응하는 제어 신호를 상기 약물 주입기로 출력하는 제어부를 포함하되, 상기 양 기반 주입 시퀀스는, 상기 전기삼투펌프에 인가될 전압 펄스 또는 전류 펄스를 정의하는 적어도 하나 이상의 펄스 블록을 포함하고, 상기 펄스 블록 각각은, 상기 전기삼투펌프에 인가되어 음압과 양압을 교번하여 발생시키는 정방향 펄스와 역방향 펄스를 포함하는 한 쌍의 펄스 신호를 정의하며, 상기 전기삼투펌프는 각각의 펄스 블록마다 음압과 양압을 교번하여 발생시켜 상기 약물을 흡입하고 토출하는 것이다.
