Abstract

L'invention concerne un dispositif d'injection (10) amélioré, pouvant être utilisé soit dans un mode manuel, pour administrer une substance médicamenteuse liquide à un patient avec un débit déterminé en continu par un élément de commande (118), soit dans un mode de régulation automatique dans lequel le débit présélectionné est maintenu par le contrôleur (102) après que le clinicien a relâché l'élément de commande (118). L'élément de commande (118) permet au clinicien de choisir entre deux débits ou de sélectionner un débit comprenant une valeur supérieure et une valeur inférieure. Si le dispositif est utilisé dans le mode de régulation automatique, le clinicien doit activer un interrupteur de commande (106B, 120, 122) pour redéfinir le débit.
