Abstract
A medical syringe comprises a cylindrical barrel 1 having therein a plunger 4 which can be axially driven by a plunger rod 3. The plunger rod 3 passes through an aperture in the centre of a finger grip 2 having two finger grip projections 2b at opposite sides thereof. A data carrier means in the form of an electrically or magnetically operable device 2c is mounted near the end of one of the two finger grip projections 2b, with preferably a device 2c mounted near the end of each finger grip projection 2b. The device 2c carries data relating to the medicament contained or to be contained within the syringe, and can be read by a suitably adapted syringe pump when the syringe is mounted thereon to be driven by the syringe pump.
