Abstract
The present invention relates to a device for the delivery of predetermined doses of liquid medicament to a patient, which medicament is intended to be inhaled by the patient or intended to be injected into the body of the patient. The device is adapted to be in a medicament delivery state and in a medicament non-delivery state. When the device is in a medicament delivery state, said device is adapted to drive a piston into a cartridge containing the liquid medicament to be delivered, with a predetermined force value. The device is designed and arranged to ensure that the predetermined dose of medicament expelled from the cartridge has a high degree of accuracy and to show the user in a simple manner how much medicament is remaining in the cartridge after a dose or several doses has/have been expelled and at the same time offering a shorter device, which is more convenient for the user when he/she has to carry it with him/her.
