摘要： A novel single use auto-injector for delivering a fixed amount of medicament is described. The auto-injector may include a sealed housing rotatably held in a cover. Once the auto-injector is positioned at the injection location, the user can transition the housing from a locked to an armed position. The user can then compress the sealed housing into the cover, triggering activation mechanisms that initiate the injection. A first activation mechanism engages an interlock to prevent reuse of the auto-injector. A second activation mechanism straightens and extends a curved needle to a set the exposed needle length. A third activation mechanism pierces a sealed reservoir allowing the medicament to be forced through the injection needle. Following the injection, the auto-injector expands and interlocks, retracting the needle into the auto-injector and preventing reuse.

摘要： The application describes a protective case for an auto-injector. The medicament contained within these auto-injectors can be susceptible to degradation due to exposure to extreme temperatures and light. Thus, one embodiment of the protective case reduces the rate of heat transfer between the internal storage compartment of the case and the external atmosphere by including particularly configured vacuum chambers. Additionally, as auto-injectors become smaller, portability can be desirable. Thus, another embodiment of the protective case includes low-profile cases that allow the user to keep the auto-injector with them, e.g., by attaching the case to a common everyday item.
