Abstract
An over pressurization relief apparatus having a manual over pressurization selector which allows a user to manually select from at least a first and second over pressurization limit. The over pressurization relief apparatus includes a pressurization chamber, a pressure relief mechanism, a seal, and a manual over pressurization selector. The pressurization of the pressurization chamber corresponds with the pressurization of the pressure infusion bag. The pressure relief mechanism prevents additional pressurization of the pressure infusion bag once the over pressurization limit has been reached. The seal is positioned between the pressurization chamber and the pressure relief mechanism to prevent the loss of pressurization from the pressure infusion bag when the pressurization in the pressurization chamber is less than the over pressurization limit.
