Abstract
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 completion of injection, and an electronic presentation of parameters such as the size of a set dose and the size of the last dose administered. The syringe also has a stop watch which is reset and started responsive to operation of the switch. The electronic presentation includes an indication of the number of hours elapsed from the activation of the switch, and may also include, for a predetermined period initially following the activation of the switch, a presentation of the number of seconds elapsed. The latter presentation can provide a visual indication to the patient of the length of time, after the injection button has been actuated to inject the dose, that the needle should remain inserted in the skin.
