Butterfly needle. Intravenous (IV) needle with a plastic 'butterfly' housing. A needle housing is termed a cannula. Needles of this design are used when short-term IV access is needed, such as when administrating a dose of drugs. A more securely fastened needle would be used for long-term therapy (such as providing an IV 'drip').
