Abstract
A syringe for dispensing a fluid comprising: a barrel for containing the fluid; a plunger having a plunger head slideably mounted and retractable within the barrel; and locking means. The locking means includes fixing means which, when engaged, permanently prevent retraction of the plunger head relative to the barrel beyond a predetermined distance, thereby limiting the travel of the plunger head.
