DRUG DELIVERY DEVICE

摘要

A component 110 for a drug delivery device 100 comprises a key validation part 112, 114 and a safety part 116. The key validation part 112 is configured to interact with a key part 113 of another component 120 of the drug delivery device during the assembly of the drug delivery device 100. In order to support the use of matching components, the safety part 116 is configured to have a different impact if the key part 122 is matched to the key validation part 112, 114 compared to if the key part 122 is not matched to the key validation part 112, 114.
