摘要：
One embodiment is directed to a method for safe injection, comprising: providing an injection assembly and inserting a plunger tip of the injection assembly to a final insertion state and releasing an associated manual insertion load. A retraction load developed sufficient to cause the plunger tip to be proximally withdrawn pulls the retractable needle proximally relative to the needle housing to a retracted state wherein a distal tip of the needle becomes mechanically locked into an encapsulated configuration wherein it is no longer exposed for injection.
