A syringe having a dose setting mechanism, a button which can be operated to inject a set dose, a switch operated at a time between the start and the completion of the injection and an electronic representation of parameters such as magnitudes of the set dose and the latest injected dose, which syringe further has a stop watch which is reset and started when the switch is operated. The status of the watch function is electronically represented and is together with the electronic represented parameters reproduced in a display showing the number of hours passed since the operation of the switch by switching on a corresponding number of 30° segments of a circle. Dose sizes are shown by common Arabic numerals.

L'invention concerne une seringue avec un mécanisme de fixation de la dose, un bouton qui peut être actionné pour injecter une dose fixée, un commutateur actionné entre le début et la fin de l'injection et une représentation électronique des paramètres tels que la grandeur de la dose fixée et la dernière dose injectée. Cette seringue a également un chronomètre qui est remis à zéro et redémarré quand le commutateur est actionné. L'état de la fonction chronomètre est représenté électroniquement, avec les autres paramètres électroniques, sur un affichage indiquant le nombre d'heures écoulées depuis l'actionnement du commutateur, en affichant le nombre correspondant de segments de cercle de 30 DEG . Les tailles des doses sont indiquées par des chiffres arabes usuels.
