<P>PROBLEM TO BE SOLVED: To provide an injection device having a limiting mechanism for preventing the setting of a dose exceeding the amount of liquid left in a cartridge. <P>SOLUTION: An injection device is of the type where a dose is set by rotating a dose setting member 6 relative to a driver 9 and away from a fixed stop in the injection device. The dose setting member interfaces with the driver such that the dose setting member can be rotated in one direction without rotating the driver. The dose is injected by rotating the dose setting member which carries the driver with it during the reverse rotation. By rotating the driver, a piston rod 3 is moved into a cartridge 2 and expels a prescribed amount of a liquid contained in the cartridge. <P>COPYRIGHT: (C)2009,JPO&INPIT |
