A device for administering antigenic material to a horse intranasally. This device is composed of a hollow tube and a blocking device. The hollow tube is long enough to reach the tonsilor tissue of a horse. This tube has a sealed end and a tapered open end. At least one opening, preferably openings along the length of this tube are positioned in a manner such that antigenic material which exits through them will reach the tonsilor tissue of the horse. The blocking device sits on the hollow tube at the point where the tapering of the open end begins. A syringe containing antigenic material is positioned at the tapered open end of the hollow tube and the antigenic material is then released in the form of small droplets on the tonsilor tissue of the horse.

Applicator for intranasal administration of vaccines to horses

A syringe for dispensing medicaments includes a barrel with a discharge end and an open end for receiving a plunger. The plunger has a head with engagement means for receiving a plunger seal. The plunger seal is a tubular member which is severed along a generally longitudinal direction providing a slit which allows the seal to be expanded for fitting onto the plunger head. Preferably the slit has an irregularity at the forward end which provides a locking configuration which prevents the seal from being twisted away from its normally tubular shape. For metered dose application, the shank of the plunger may be threaded for the desired placement of a stop ring threaded on the shank. In one form, the ring and barrel have interlocking means to prevent the ring from moving backward when pressure is applied to the plunger after the ring has reached the barrel.
