Single-use syringe.

摘要

A syringe which is suitable for discarding after a single use comprises a generally tubular syringe body (10) which has a double-ended hollow needle (12) extending generally axially through a first, closed end thereof and is open at its second end to permit insertion of a liquid container (16) such as an ampoule containing a liquid material to be injected. A removable plunger rod (19) is provided to enter such a container within the syringe body to inject liquid from it via the needle, and a resilient retaining means (15) extends generally radially inwardly from the open end of the syringe body, to allow insertion of a liquid container but prevent its subsequent withdrawal.
