    摘要： Methods and apparatus for enhancing reliability of, and monitoring, the operation of airway valves to enhance patient safety. Pneumatic control line pressure (positive or negative) for actuation of the airway valve may be specified at a given magnitude or within a selected range and monitored continuously. Reduced or excessive pressure may be compensated by actuation of a pressure source or a bleed valve, and monitoring may be effected so as to warn the user of any deviation from the range, or deviations of selected magnitudes or frequencies or a combination thereof. The inspired volume of CO2 may be monitored using air flow and CO2 sensing, with detection of excessive CO2 volume triggering a warning. Similarly, measured end-tidal or end-inspired CO2 or other appropriate measures of CO2 concentration may be employed as a warning trigger. Other driving energy sources for airway valves, and monitoring thereof, are also disclosed.

    摘要： An airway adaptor that includes a tubular body having a first gas flow passage defined therein. A protrusion extends from an interior wall of the tubular body into the gas flow passage. The protrusion includes a distal end portion spaced apart from the interior wall of the tubular body, and a second gas flow passage defined through the protrusion. An inlet to the second gas flow passage is provided at the distal end portion of the protrusion, and an outlet of the second gas flow passage is provided at an exterior portion of the tubular body. A pair of sidewalls are disposed on the distal end portion of the protrusion. Each sidewall is generally parallel to a direction of a flow of gas through the first passage. The inlet of the second gas flow passage is disposed between the pair of sidewalls.

    摘要： The present invention provides a method and device for conveniently setting the volume of a variable-length tubing loop used in a re-breathing circuit to various selected predetermined values. The device includes a card of an inelastic, disposable material which is attachable to a portion of the tubing loop or adjacent structure and which has marked on it several positions to which the tubing loop can be extended to set the volume of the loop at selected predetermined values. The card is preferably formed of a substantially rigid material which may be configured to fold around the tubing loop and adjacent structures to provide support and protection during shipping and handling of the device. The card may include instructions for use of the tubing loop printed on an outer surface thereof. Some or all of the card may be detachable from the tubing loop so that once the desired tubing volume is set, all or a portion of the card may be removed and disposed of.

    摘要： An airway adapter suitable for use with patients having low tidal volumes, e.g., neonates, which minimizes deadspace in the airway and promotes smooth flow of gases through the adapter. The adapter includes a first portion adapted to couple to a tubular adapter, such as an endotracheal tube adapter, and a second portion adapted to couple to a ventilation tube. A longitudinally compressible member is coupled to the first portion to minimize deadspace in the adapter. A portion of the compressible member resiliently contacts and seals against a tubular adapter upon assembly of the airway adapter therewith.

    摘要： An airway valve for re-breathing, a ventilator circuit including same and a method of operating the airway valve. The airway valve includes a housing having first and second primary passages extending through the wall thereof and mutually directly communicating within the housing through a spring-biased valve assembly in the form of first and second diaphragms respectively and simultaneously movable in tandem within the housing into and out of contact with first and second valve seats on a valve body with which the first primary passage communicates. The valve assembly also controls diversion of air flow between the first primary passage and the second primary passage into and through an enlarged volume defined by a re-breathing loop external to the housing via first and second diversion passages, which also extend through the wall of the housing. In a normal operating mode of the airway valve, a first diaphragm engages the first valve seat to preclude communication between the first primary passage and the first diversion passage, while the second diaphragm remains out of contact with the second valve seat to permit communication within the housing between the first and second primary passages and directing air flow therethrough. In a re-breathing mode of the airway valve, the second diaphragm contacts the second valve seat to preclude direct communication between the first and second primary passages, while withdrawal of the first diaphragm from the first valve seat opens communication between the first primary passage and the first diversion passage routing air flow through the re-breathing loop and back to the interior of the housing via the second diversion passage, which is in communication with the second primary passage. The diaphragms are spring-biased to the normal operating mode of the valve, and moved to the re-breathing mode by application of a differential air pressure to one of the diaphragms to overcome the spring force.
