Abstract

A filling device for filling an injection syringe is provided which enables the user to count the intake dosage by means of a sound indicator which may be mechanical, electrical or an electronic sound device. The filling device includes a movable syringe holder to which is attached a removable syringe that is connectable to a medicinal bottle. The filling device mounts a gear which is movable one gear tooth at a time to actuate a linear gear to which the syringe is mounted. A spring loaded ball bearing is biased against the gear wheel and produces a distinctly audible clicking sound when the gear moves a single notch. These clicking sounds can be counted by a user when the attached syringe holder moves, and hence will accurately indicate the amount of liquid medicine drawn into the syringe. The same device may be connected to a microprocessor controlled voice device to obtain a suitable readout indicating the amount of liquid medicinal uptake by the syringe.
