Abstract

An apparatus for automatically effecting the injection of a liquid into an organism, characterized in that the successive displacements of the piston of the injection syringe are obtained by a ratchet rack, one end of which is integral with the piston of the syringe and whose the other end is subjected to the action of a deformable membrane against which the pressure gas from a storage container is exerted by means of a distributor that can alternatively put the membrane in communication with said container and with the atmosphere .
