ABSTRACT:
An improved cartridge for use in hypodermic syringes is disclosed in which the hollow tubular cartridge body has a first end which has a resilient seal thereon and which engages both the end of the cartridge and a portion of the periphery thereof adjacent the end. The first seal member is also capable of engaging the internal nozzle of the syringe, if one exists, as well as engaging the inner surface of the barrel of the syringe. The opposed end of the cartridge body, which is normally contacted by a plunger to eject the contents, has a second seal member or plug, at least a portion of which is partially received internally of the cartridge and has annular ribs which perform as O-rings and contact the inner surface thereof for sealing purposes. A lip fits over the second end of the cartridge body to achieve a three-way seal at that point and also seals against the inner surface of the barrel of the syringe per se. This second seal member is deformable so that upon actuation of the plunger, the second seal will deform inside the cartridge body to resist back pressure and thereby prevent leakage.
