摘要:
In one aspect of the subject invention, a drug delivery device is provided which includes a reservoir for containing a medicament and has a proximal end and a distal end, the medicament including a suspension of solids in a liquid carrier. Further, the drug delivery device includes a needle in fluid communication with the reservoir and having a distal end for injection into a patient, and a proximal end in the reservoir. An accumulation surface is defined at least partially about the needle, distally of the proximal end of the needle. The accumulation surface defines a distally-extending indentation which is sized and shaped to collect, during use, solids that come out of suspension. Advantageously, with the subject invention, the accumulation surface allows for solids to accumulate at a location spaced from the proximal end of the needle, thereby minimizing the possibility of clogging the needle.
