Abstract
The invention features a needle guard for a hypodermic syringe that will prevent repuncture by a used needle. The needle guard has a flexible membrane that expands when pressure actuated to cover and protect the injecting tip of the syringe needle. The membrane is characterized by a small, unobtrusive profile in the inactivated state.
