The present invention relates to a medicament injection apparatus, particularly suitable for use by those with diabetes in which, in use, once a desired dosage of medicament has been selected and expelled from the medicament cartridge into the body of the patient, the injected medicament is allowed to disperse locally from the injection site within the patient's body before the needle arrangement is removed from the patient's body. It is considered to be a problem that in known medicament injection devices the injection interval, that is the time elapsed since a previous injection, is measured following completion of a delivery stroke rather than from dispersion of the injected medicament. A medicament injection device is disclosed in which the time elapsed following an injection operation is calculated from the end of a predetermined period during which medicament is permitted to disperse subsequent to completion of an injection stroke.
L'invention se rapporte à un appareil d'injection de médicament, particulièrement approprié pour les sujets atteints de diabètes. Lorsqu'une dose désirée de médicament a été sélectionnée et expulsée des cartouches de médicament dans le corps du patient, le médicament injecté peut se disperser localement du site de l'injection dans le corps du patient avant que l'agencement d'aiguille soit retiré du corps du patient. Le problème réside dans le fait que, dans les dispositifs d'injection de médicament connus, l'intervalle d'injection, qui est le temps écoulé depuis l'injection précédante, est mesuré au terme de la course d'administration plutôt que de la dispersion du médicament injecté. Un dispositif d'injection de médicament est décrit dans lequel le temps écoulé après avoir pratiqué une injection est calculé à partir de la fin d'une période prédéterminée pendant laquelle le médicament peut se disperser au terme d'une course d'injection.
