摘要：
Described herein are syringe devices, systems and methods. In general, the syringe may include a first chamber and a cartridge movable within the first chamber. The cartridge may include a cartridge chamber and a valve in fluid communication with the cartridge chamber and the first chamber and having an open configuration and a closed configuration. The valve may allow movement of a liquid out of the cartridge chamber while in a open configuration. The cartridge may also include a second end, movable within the cartridge chamber, and a locking mechanism having a locked configuration and an unlocked configuration, the locking mechanism preventing movement of the second end within the cartridge chamber while in the locked configuration.
