Abstract:
A filling system including an anesthetic storage container and an anesthetic vaporizer having a liquid container, the filing system for use in transferring an anesthetic between the anesthetic storage container and the liquid container within the anesthetic vaporizer, the filling system comprising:a filling device positioned on the anesthetic vaporizer to receive the anesthetic storage container;at least one filling conduit having a first end including a flow opening in communication with the liquid container of the anesthetic vaporizer and a second end coupled to the filling device, the filling conduit providing a pathway for both the anesthetic from the anesthetic storage container and a replenishment gas to flow between the anesthetic storage container and the liquid container of the anesthetic vaporizer; andclosing means operatively positioned adjacent to the flow opening of the filling conduit, the closing means being movable to a closing position when a first pressure in the anesthetic storage container substantially exceeds a second pressure in the liquid container of the anesthetic vaporizer, whereby when the closing means is in the closing position, the closing means closes the flow opening of the filling conduit to prevent anesthetic liquid from flowing from the anesthetic storage container into the liquid container of the anesthetic vaporizer.
