INJECTION DEVICE HAVING POLYPARAXYLYLENE COATED CONTAINER

摘要

An injection device (10) comprises a plastic or metal container (26) adapted to contain a charge of medicament. The container has at least an inner surface coated with polyparaxylylene (29). A needle (40) is cooperative with the container so as to be communicable with the medicament and provides a passage through which the medicament can be forced into the flesh of an individual. A plunger (36) is disposed in the container in slidably sealed relation with the polyparaxylylene coating provided on the inner surface of the container. The plunger is movable through the container toward a generally forward end thereof to force the medicament through the needle and into the flesh of the individual.
