Abstract
A syringe which is suitable for discarding after a single use takes the form of a generally tubular syringe body which has a double-ended hollow needle extending generally axially through a first, closed end of the body and is open at its second end to permit insertion of a liquid container such as an ampoule containing a liquid material to be injected. A removable plunger rod is provided to enter such a container within the syringe body to inject liquid from it via the needle, and one or more resilient projections extend generally radially inwardly from the open end of the syringe body, to allow insertion of a liquid container but prevent its subsequent withdrawal.
