Abstract
Systems and methods are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a vaporizing chamber configured to hold a liquid anesthetic agent, and an inductive heating element positioned exterior to the vaporizing chamber and housed within a gas-tight barrier, the inductive heating element operated to selectively heat a target.
Claims20
A system for an anesthetic vaporizer, comprising:
- a vaporizing chamber configured to hold a liquid anesthetic agent;
- and
- an inductive heating element positioned exterior to the vaporizing chamber and housed within a gas-tight barrier, the inductive heating element operated to selectively heat a target component of the anesthetic vaporizer.
A method for an anesthetic vaporizer, comprising:
- supplying power to an inductive heating element to heat a target at least partially disposed within a vaporizing chamber of the anesthetic vaporizer, the vaporizing chamber holding liquid anesthetic agent and the inductive heating element positioned within a gas-tight barrier that isolates the heating element from the vaporizing chamber;
- and
- adjusting the power supplied to the inductive heating element based on a temperature feedback signal.
A system for an anesthetic vaporizer, comprising:
- a vaporizing chamber holding an anesthetic agent;
- an inductive heating coil arranged exterior to the vaporizing chamber at a position that overlaps with a ferromagnetic component of the anesthetic vaporizer;
- a vapor delivery passage that fluidically couples the vaporizing chamber to a patient breathing circuit;
- a gas-tight barrier surrounding the inductive heating coil;
- and
- a controller housed within the gas-tight barrier, the controller storing executable instructions in non-transitory memory that, when executed, cause the controller to:
- supply power to the inductive heating coil to heat the ferromagnetic component to a temperature setpoint selected to flow a desired amount of vaporized anesthetic agent from the vaporizing chamber to the patient breathing circuit;
- and
- adjust the power supplied to the inductive heating coil based on an electronic feedback signal.
