ABSTRACT:
A pressure liquid injector, for purposes of immunization includes one part in the shape of a pistol which houses the oil-hydraulic assembly for storage of energy and another part which comprises the vaccine suction and injection assembly. These two assemblies may be quickly connected and disconnected one from the other without permitting entrance of air into either of the two systems, particularly into the ducts and places where the vaccine is circulated and stored. Thus, a number of vaccine assemblies can be kept in a refrigerator and used one at a time in conjunction with the same hydraulic assembly, according to the need for application.
