ABSTRACT:
A microsyringe comprised of a barrel provided with an axial bore, at the forward or outlet end of which is affixed a hollow needle, and within the opposite end of which is fitted a slidable plunger. The forward terminal end of the plunger is hollow and provided with a fixed seal. The fixed seal is of cylindrical shape, and constituted of a resilient, flexible or semi-flexible material, of external diameter substantially equal to or slightly larger than the internal diameter of the bore, and includes a shank or projection of relatively smaller diameter which extends into the hollow forward portion of the plunger. The seal is held within the forward end of the plunger by inward thrust of the plunger wall, as produced by punching or crimping the wall formed within the hollow end of the plunger to force the wall inwardly against the seal projection to hold the seal firmly in place, and in proper alignment.
