Abstract
Abstract The present invention relates to a method and a device for injecting humans and animals with a pharmaceutical preparation, wherein the preparation is held in a rigid carrier (5) and the carrier is carried through the skin into the body by means of gas pressure, and wherein during carrying of a rigid carrier (5) into the body by means of gas pressure the device with which the carrier is carried into the body is held against the body. The invention likewise relates to a device for injecting animals or humans with a pharmaceutical preparation, wherein a chamber (2) is present in which a carrier (5) containing the pharmaceutical preparation can be placed, a barrel (1) connecting onto this chamber and means for carrying the carrier by means of gas pressure through the barrel into the body for injecting, wherein means are present for blocking the use of the device when it is not pressed against a body.
