Abstract
Disclosed is a medical injection device () comprising a needle assembly () having a cannula () and a telescopic shield () for covering the distal tip () in a no use situation. The telescopic shield further carries a cleaning reservoir () for cleaning the needle cannula between two subsequent injections.

In one example, the overflow reservoir is formed as a channel ().
