DRUG DELIVERY DEVICE |
摘要 |
There is provided drug delivery devices comprising a drug container assembly with a needle and automatic needle insertion and drug delivery mechanisms. Aspects of the devices described include a noise-generation mechanism to indicate the completion of drug delivery, a mechanism for triggering drug delivery following needle insertion, front-end activation of the device and a safety mechanism for covering the needle after use and methods of assembly of the devices. |

1. A drug delivery device comprising:
a drug container containing a drug; a plunger within the drug container, movement of the plunger within the drug container being operative to deliver the drug from the drug container; and a drive mechanism, the drive mechanism comprising: a stored energy source, the stored energy source configured to release energy by expanding from a compressed state, a first drive element coupled to the stored energy source, and a second drive element coupled to the first drive element and positioned between the first drive element and the plunger, wherein in a first position of the drive mechanism the first drive element is constrained from moving in an axial direction relative to the second drive element but in a second position of the drive mechanism the first drive element is free to move in the axial direction relative to the second drive element such that a first surface of the first drive element is driven against a first surface of the second drive element by the stored energy source to produce an audible signal indicative of the completion of drug delivery from the drug container. |
