Injection device

Drug infusion device

A method and apparatus are provided for providing a plurality of injections from a fluid reservoir. The apparatus includes a fluid controller for controlling the flow of fluid from the fluid reservoir to a needle. An actuator selectively actuates the fluid controller to provide a dose of medicament from the fluid reservoir. The fluid controller also is configured to calculate the volume of fluid in the fluid reservoir required to provide a dose having a desired number of units of medicament for an injection. The apparatus may also include a detector configured to detect a characteristic indicative of the fluid pressure in the needle. The method includes selecting the number of units to be dispensed during an injection, automatically calculating the injection volume required to dispense the selected number of units based on the calculated unit volume and tracking the total number of units dispensed during a series of injections.
