Abstract
Disposable injection devices are disclosed herein. In an exemplary arrangement, the disposable injection device comprises an annular sleeve, a predetermined pre-injection quantity of a substance configured for selective injection, and a temperature control element. The annular sleeve at least partially defines a dispensing chamber therein. The predetermined pre-injection quantity of the substance configured for selective injection is disposed within the dispensing chamber. The temperature control element is operably connected to the dispensing chamber, and is configured to selectively heat the substance to a predetermined temperature. The substance expands from the pre-injection quantity at the predetermined temperature to an injection quantity whereby the injection quantity is greater than a volume defined by the dispensing chamber. In this manner, a predetermined minimum quantity of the substance is self-expelled from the dispensing chamber.
