Abstract
A safely disposable unit dose syringe is achieved by sealing the fluid to be administered into a plastic or otherwise inexpensive, deformable container such as a plastic baggie and attaching to the container a needle which can be moved from a protected compartment to an exposed position for administering the fluid. The needle is withdrawn to the protected position after use for safe disposal. After use the container cannot be refilled without the use of fairly elaborate and costly equipment. The syringes can be produced in the form of a bandoleer for administration by means of a gun-like device, the contents of each syringe being delivered in response to the squeezing of a trigger-like mechanism.
