Abstract
Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, a liquid anesthetic agent container includes a base region, an interior of the base region configured to hold liquid anesthetic agent, an adapter region, and a capillary force vaporizer (CFV) housed in the adapter region. The adapter region includes a coupling end configured to couple to a patient breathing circuit to supply anesthetic agent vaporized by the CFV to a patient.
Claims20
A liquid anesthetic agent container, comprising:
- a base region, an interior of the base region configured to hold liquid anesthetic agent;
- an adapter region;
- and
- a capillary force vaporizer (CFV) housed in the adapter region, the adapter region including a coupling end configured to couple to a patient breathing circuit to supply anesthetic agent vaporized by the CFV to a patient.

A system, comprising:
- a liquid anesthetic agent container including a base region configured to hold liquid anesthetic agent, an adapter region, and a capillary force vaporizer (CFV) housed in the adapter region, the adapter region including a coupling end and a first electrical connector;
- and
- a patient gas machine including a port configured to couple to the coupling end of the liquid anesthetic agent container and a second electrical connector configured to couple to the first electrical connector.
A system, comprising:
- a liquid anesthetic agent container including a base region and an interior configured to hold liquid anesthetic agent;
- a capillary force vaporizer (CFV) housed in an adapter configured to couple to the base region, the CFV including a heating element;
- a vapor reservoir coupled to the adapter;
- a gas passage configured to flow fresh gas, the gas passage fluidically coupled to the vapor reservoir;
- at least one sensor coupled to the gas passage;
- and
- a controller storing non-transitory instructions executable to:
- determine a concentration of vaporized anesthetic agent in the gas passage downstream of the vapor reservoir based on output from the at least one sensor;
- and
- adjust a temperature of the heating element based on a difference between the determined concentration and a setpoint concentration.
