Abstract
A medicament injection device in which the time elapsed is calculated from the end of a predetermined period during which medicament is permitted to disperse subsequent to completion of an injection stroke. The medicament injection device is particularly suitable for use by those with diabetes in which once a desired dosage of medicament has been selected and expelled from the medicament cartridge into the body of the patient, the injected medicament is allowed to disperse locally from the injection site within the patient's body before the needle arrangement is removed from the patient's body.

- a sounder,
- wherein upon completion of an injection stroke, a predetermined period of time is allowed to lapse during which medicament is permitted to disperse, and
- wherein the sounder generates an audible signal indicating to the user when to remove the needle from the body after said dispersion of an injected medicament;
- a drive means;
- and
- a timer having a control means,
- wherein the timer measures the predetermined period from completion of operation of the drive means and the control means resets the timer upon completion of the predetermined period to measure a time elapsed following the injection operation.
