Abstract
A syringe which has an intended pressure limit. The syringe includes a syringe body, and a pressure-limiting mechanism is disposed inside the syringe body. The pressure-limiting mechanism may comprise a valve body which is spring biased in the syringe body. In one embodiment, the pressure-limiting mechanism is provided in the form the valve assembly having a valve seal which moves into sealing engagement with an internal wall of a valve bore in the syringe housing once the intended pressure limit is reached. In another embodiment, the pressure-limiting mechanism is provided in the form of the valve assembly having a valve seat which moves into sealing or plugged engagement with a valve plug once the intended pressure limit is reached. Regardless of the exact configuration, preferably the syringe is simple, reliable, easy to assembly, and easy to sterilize given its low number of parts.
