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.

A filler adaptor assembly includes a base, an outer ring, and iris members. The base has a central opening. The outer ring is disposed circumferentially about the base and is rotatable relative to the base. The iris members are pivotably coupled to the base. The iris members cooperate to define an iris opening and are movable to vary the iris opening. The iris members are coupled to the outer ring, and move between an open position and a closed position when the outer ring is rotated relative to the base.

Systems and methods are provided for anesthetic agent level sensing. In one embodiment, a system for an inductive level sensor for an anesthetic vaporizer includes a measurement target positioned around a rod that extends within a chamber configured to hold liquid anesthetic agent, the rod configured to be at least partially submerged in the liquid anesthetic agent and the measurement target configured to slide vertically along a length of the rod and rest on a surface of the liquid anesthetic agent, and a strip of inductive transmitter coils and receiver coils positioned external to the chamber, a length of the strip aligned with the length of the rod, the transmitter coils configured to generate a magnetic field that surrounds the rod and the measurement target and the receiver coils configured to sense changes in the generated magnetic field at a vertical location of the measurement target on the rod.

Disclosed is an anesthetic evaporator, comprising a housing, a drug reservoir, and a cover movably connected to the housing, wherein the drug reservoir is provided with a drug adding barrel arranged corresponding to the cover, and further comprising a mechanical pressure relief assembly and a linkage mechanism, wherein the mechanical pressure relief assembly is connected to the drug reservoir; the mechanical pressure relief assembly has a first state in which the pressure within the drug reservoir is maintained and a second state in which the pressure within the drug reservoir is released; when adding a drug, the operation action on the anesthetic evaporator drives the linkage mechanism, and the linkage mechanism drives the mechanical pressure relief assembly to switch same from the first state to the second state. The pressure of the anesthetic evaporator can be mechanically released, so that greater and reliability are realized.

Systems and methods are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a housing defining a sump, the sump configured to hold a self-contained supply of liquid anesthetic agent, a heating element electrically coupled to an electrical mating component, a gas inlet passage and a gas outlet passage, a manifold fluidically coupled to the gas inlet passage and the gas outlet passage, the manifold coupled to the housing and forming a gas-tight seal with the sump, and a quick disconnect pneumatic system coupled to the gas inlet passage and the gas outlet passage, sealing the gas inlet passage and the gas outlet passage from atmosphere.

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.

A filler adaptor assembly includes a base, an outer ring, and iris members. The base has a central opening. The outer ring is disposed circumferentially about the base and is rotatable relative to the base. The iris members are pivotably coupled to the base. The iris members cooperate to define an iris opening and are movable to vary the iris opening. The iris members are coupled to the outer ring, and move between an open position and a closed position when the outer ring is rotated relative to the base.

The MedicSMART system can be a replenishment system for personal medical kits. The personal medical kit can house an inventory of personal use medical supplies within a container that is in a location personally associated with a user. Each medical supply can have a radio-frequency identification (RFID) tag affixed thereon. The payment artifact can be used for the user's electronic transactions. The MedicSMART system can be configured to automatically replenish the inventory of the personal medical kit using a client device, supply thresholds, supplier data, and a server. The client device can be installed within the container to collect data from the RFID tags. The supply thresholds can define minimum values for the medical supplies. The supplier data can define suppliers for purchasing the medical supplies. The server can be configured to automatically order medical supplies to maintain the personal medical kit in an acceptable state.

An anesthetic vaporizer system includes a reservoir containing anesthetic agent, an agent level sensor measuring an agent level of the anesthetic agent in the reservoir, a display, and a controller. The controller is configured to receive agent level measurements from the agent level sensor over a time period, and determine the anesthetic agent is being added to the reservoir from an agent source based on the agent level measurements over the time period. A filling status is determined based on the agent level measurements and a filling status indicator is displayed based on the determined filling status.

Methods and systems are provided for anesthetic agent leakage diagnostics. In one embodiment, a method for diagnosing leaks in an anesthetic vaporizer includes calculating a leakage rate based on measurements of an anesthetic agent level in a sump of the anesthetic vaporizer, the measurements received from a fluid level sensor at a first time and a second time, and outputting a maintenance alert responsive to the leakage rate exceeding a threshold.
