  • 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.

  • 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.

  • Publication number: 20210093826
    Abstract: An anesthesia vaporizer system includes a sump chamber, a variable volume reservoir within the sump chamber, and an anesthetic vaporizer. The variable volume reservoir is configured to contain anesthetic agent. A pressurized gas source is connected to the sump chamber and configured to maintain a constant pressure within the sump chamber to compress the variable volume reservoir to force the anesthetic agent through the anesthetic vaporizer, which vaporizes the liquid anesthetic agent for delivery to a patient.

  • Patent number: 9433742
    Abstract: A vaporizer filler includes a fill port. The fill port defines an open interior. The open interior is configured to receive the nozzle of an anesthetic bottle. An agent reservoir is configured to receive and store anesthetic agent. A valve is disposed between the open interior and the agent reservoir. At least one vent extends through the fill port. A method of filling a vaporizer includes inserting the nozzle of a bottle filled with anesthetic agent into a vaporizer filler. At least one vent is occluded from fluid communication. Fluid communication between and open interior and an agent reservoir is opened. Anesthetic agent is poured into an agent reservoir of a vaporizer. Fluid communication is closed between the open interior and the agent reservoir. At least one vent is opened to fluid communication with the open interior. Pressure within the open interior is released through the at least one vent.
