Abstract
An inhaler for electrical dosing of pure substances or preparates consisting of chemical and biological substances mainly used as drugs. The inhaler, which comprises a microprocessor thereby offers a flexible and measurable dose for the chemical and biological substances in the form of powders, or in the form of small drops or aerosols. The dosing is done electrically via first field generating member (23) whereby the substance is transmitted to a transmitting member which attracts the substance, from which the substance is then emitted by influence from another electrical field generated by a second field generating member (32), and the substance is finally mixed with air which is conventionally inhaled.
