Abstract
A fluid delivery device is provided. The device comprises an internal container, an external container and a first delivery pipe. The internal container has a first space for containing a fluid to be delivered. The external container substantially surrounds the internal container to form a substantially sealed second space between the internal container and the external container, wherein the second space is for an assistant liquid. The assistant liquid is heated to raise the pressure in the second space, and then, the internal container is pressed, thereby driving the fluid out along the first delivery pipe.
