  • Publication number: 20220016385
    Abstract: A system for tracking anesthetic agent in a vaporizer reservoir can include a mass flow sensor configured to measure a flow rate entering or exiting a vaporizer chamber, a gas pressure sensor configured to measure a pressure of a mixed gas provided from the vaporizer chamber, and a processor to calculate a remaining agent time based on at least the gas flow rate, the pressure of the mixed gas, and an anesthetic concentration in the mixed gas. The processor can also provide the remaining agent time for display to a clinician.

  • Publication number: 20210369995
    Abstract: Various methods and systems are provided for determining a quality of a medical gas flow. In one example, a method for a medical gas quality monitoring system includes obtaining measurements of a medical gas via a plurality of sensors, the plurality of sensors including at least one of a humidity sensor, a particulate matter sensor, a carbon dioxide sensor, and a total volatile organic compound (tVOC) sensor, determining a gas quality index of the medical gas based on the obtained measurements, and outputting the determined gas quality index.

  • Patent number: 11154686
    Abstract: A system for tracking anesthetic agent in a vaporizer reservoir includes a mass flow sensor configured to measure a flow rate entering or exiting a vaporizer chamber, a gas pressure sensor configured to measure a pressure of a mixed gas provided from the vaporizer chamber, a gas temperature sensor configured to measure a temperature of the mixed gas provided from the vaporizer chamber, and an agent time module executable on a processor. The agent time module is configured to calculate a remaining agent time based on at least the gas flow rate, the pressure of the mixed gas, the temperature of the mixed gas, and an anesthetic concentration in the mixed gas. The remaining agent time is then provided for display on a display device.

  • Publication number: 20210322694
    Abstract: An anesthesia vaporizer system includes a vaporizer reservoir forming a sump chamber that contains liquid anesthetic agent and a fill chamber isolated from the sump chamber configured to receive liquid anesthetic agent from a refill container. A piston is in the sump chamber configured to maintain a constant force on the liquid anesthetic agent in the sump chamber, and a transfer valve is configured to permit the liquid anesthetic agent to flow from the fill chamber to the sump chamber. The vaporizer reservoir has an outlet port that delivers the liquid anesthetic agent from the sump chamber to a vaporizing system that vaporizes the liquid anesthetic agent for delivery to a patient.

  • Patent number: 11077268
    Abstract: An anesthesia vaporizer system includes a vaporizer reservoir forming a sump chamber containing a liquid anesthetic agent, a piston that forms a first chamber on a first side of the piston. The vaporizer reservoir has a fill port configured to receive a refill container containing liquid anesthetic agent and to permit flow into the first chamber. A motor moves the piston between a first position and a second position, wherein the volume of the first chamber increases as the piston moves from the first position towards the second position. The liquid anesthetic agent is thereby drawn from the refill container into the first chamber. A transfer valve is configured to permit the liquid anesthetic agent to flow from the first chamber into the sump chamber. An outlet port delivers the liquid anesthetic agent from the sump chamber into a vaporizing system that vaporizes it for delivery to a patient.

  • Patent number: 6528739
    Abstract: A fluid sensor apparatus for monitoring fluid in a container. The fluid sensor apparatus comprises a housing having an upper hook extending from a top thereof to allow the housing to be suspended. A lower hook is telescopically received in the housing and extends from a bottom thereof. The lower hook is adapted for suspending a fluid container therefrom. The lower hook is movable relative to the housing. A cam member is located inside the housing and is movable relative thereto. The cam member is coupled to an upper end of the lower hook. The cam member has a stepped gradation. A biasing member is coupled between a lower shoulder of the cam member and the housing. The biasing member is adapted to apply a force against the cam member to cause the cam member to be biased upward relative to the housing to an upper position. A switch is coupled to the housing and has an actuator located in relation to the stepped gradation of the cam member.
