Abstract: One or more anesthetic vaporizers may be fluidly connected to the anesthetic delivery machine via a vaporizer mounting bar. The vaporizer mounting bar may include multiple vaporizer mounting positions. Each vaporizer includes interlock pins that extend when the vaporizer is opened and prevent the vaporizer from being opened when pushed in. When a first vaporizer is opened, its interlock pins may extend and cause the interlock pins of adjacent vaporizers, and vaporizers within a chain of interlock pin connections, to be pushed in, preventing the other vaporizers from being opened simultaneously with the first vaporizer. In various embodiments, a paddle system may translate the extension of an interlock pin from one vaporizer to the interlock pins of each of the other vaporizers in the direction of the extension, including the interlock pins of vaporizers in non-adjacent and non-chain positions.

Abstract: Provided herein is a hybrid system for generating oxygen on-board an aircraft for passengers and/or flight crew to breath. The system includes a first chemical oxygen generator component configured to promptly supply oxygen suitable for breathing upon an emergency situation arising and during an initial descent mode. Heat produced from the exothermic decomposition reactions inherent in several types of chemical oxygen generators can be harvested and feed to a second oxygen generator. The second oxygen generator is a solid electrolyte oxygen separation system that catalytically separates oxygen from air inside specialized ceramic materials at high temperatures, about 650° C. to 750° C., using electrical voltage. The ability to feed heat from the first oxygen generator to the second oxygen generator substantially reduces the lag time until the second ceramic oxygen generator is available to take over as the oxygen supply.

Abstract: Systems and methods for detecting developing faults in a flow generator or ventilator during therapeutic use thereof are provided. The motor current may be measured to estimate the torque input by the motor, while the output torque from the impeller may be determined (e.g., as inferred from the motor control system model and/or by consulting a lookup table). One or more transducers may collect data useful in determining the input and output torques. A difference between the input (to the motor) torque and the output (from the impeller) torque may be calculated. The difference, optionally filtered using a low-pass filter to reduce noise, may be compared to a predetermined threshold once or over a period of time to detect gross failures and/or developing failures. Once a failure or developing failure is detected, a user may be alerted and/or the flow generator may be placed into a “service required” mode.
