  • Patent number: 10987475
    Abstract: Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, a system includes an anesthetic agent reservoir, a pump fluidically coupled to the agent reservoir, an injector configured to receive pressurized anesthetic agent from the pump, a vaporizer comprising a heated chamber configured to receive and vaporize the anesthetic agent injected by the injector and supply a mix of the vaporized anesthetic agent and medical gas to a subject via a supply line, and a controller. The controller stores instructions executable to determine a concentration of the vaporized anesthetic agent in the mix and adjust one or more injector parameters based on a difference between the concentration of the vaporized anesthetic agent and a commanded concentration.

  • Publication number: 20190201656
    Abstract: Liquid accumulators and methods for reducing pulsations of a liquid flow are disclosed. A liquid delivery system comprises a pump configured to drive liquid to a pipe. The pipe is configured to transmit a liquid flow. A liquid accumulator is fluidically connected to the pipe. The liquid accumulator comprises a chamber containing the liquid and a vapor column and a power source configured to input energy to the chamber to generate vapor from the liquid to form the vapor column. The vapor column constitutes a gas spring to reduce pulsations of the liquid flow in the pipe. The spring rate of the gas spring can be adjusted by changing the input energy level from the power source to the chamber.
