| abstract |
A needle assembly ( 2 ) for a drug delivery device ( 1 ) comprises a needle seal ( 3 ), a needle retainer ( 4 ) and a needle ( 5 ). The needle retainer ( 4 ) secures the needle ( 5 ) against displacement with respect to said needle retainer ( 4 ) when a dose of drug is being delivered. The needle seal ( 3 ) is configured to push onto the needle retainer ( 4 ) after delivering the dose of the drug, thereby unlocking the needle ( 5 ) from the needle retainer ( 4 ). |
