Abstract
An injection device includes a dispensing chamber, a plunger, a controller, a temperature control device, and a memory device. The dispensing chamber has an inner surface and an outer surface. The inner surface defines a cavity for receiving a quantity of a substance. The plunger is engaged with the inner surface of the dispensing chamber, is capable of sliding in the cavity of the dispensing chamber, and is fluidly sealed to the inner surface of the dispensing chamber. The controller controls the operation of the injection device. The temperature control device at least partially surrounds the dispensing chamber. The memory device has a parameter stored on it. The controller uses the parameter from the memory device to operate the injection device.
