Therapy gas delivery systems that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.

The present disclosure relates to a filter apparatus for filtering liquid from a gas, the apparatus having a first housing having a gas inlet and a gas outlet; a first filter media disposed in the first housing; a second filter media disposed in the housing; and a second housing forming a first collection basin disposed in the flow path between the first filter media and the second filter media, so that a path is defined for the gas flowing from the inlet, through the first filter media, past the collection basin, through the second filter media, and to the outlet. The present disclosure also relates to a method of passing a gas through a coalescing filter media and through a hydrophobic filter media.

Apparatus and method for filtering liquid particles from inspiratory gas flow of a patient breathing circuit affiliated with a ventilator and/or nitric oxide delivery system

A reservoir for an anesthetic vaporizer is disclosed herein. The reservoir includes an open interior and a high-pressure channel in communication with the open interior. The high-pressure channel is configured to transfer an anesthetic agent from a storage container into the open interior when a pressure level within the storage container exceeds a pressure level within the open interior. The reservoir also includes a low-pressure channel in communication with the open interior. The low-pressure channel is configured to transfer the anesthetic agent from the storage container into the open interior when the pressure level within the storage container is less than or approximately equal to the pressure level within the open interior. The low-pressure channel and the high-pressure channel are configured to prevent the open interior from being overfilled with the anesthetic agent under conditions wherein the pressure level within the storage container exceeds the pressure level within the open interior.

Method and apparatus for preventing drug reservoir overfill

A system for facilitating the delivery of a liquid anesthetic agent from an anesthetic bottle to an anesthetic vaporizer. The system includes a bottle adapter, an anesthetic bottle and a filler arrangement positioned on the anesthetic vaporizer. The bottle adapter and filler arrangement each include a keyed configuration such that only the correct type of anesthetic agent can be emptied into the anesthetic vaporizer. The bottle adapter includes an adapter valve assembly that engages a filler valve assembly contained within the filler. The dimensions and arrangement of the adapter valve assembly and the filler valve assembly insure anesthetic agent is delivered to the anesthetic vaporizer only when the anesthetic agent can safely flow from the anesthetic bottle to the anesthetic vaporizer.
