Abstract: A collapsible reservoir system is disclosed herein. The collapsible reservoir system includes a first tube pneumatically connected to the collapsible reservoir, and a second tube pneumatically connected to the collapsible reservoir. The second tube is configured to generally remain open in the absence of an externally applied compressive force. The second tube is positioned relative to the collapsible reservoir such that a compressive force applied to the collapsible reservoir can also compress and thereby restrict the second tube. A corresponding method for controlling the pressure of a collapsible reservoir system is also provided.

Abstract: An arrangement and method is provided for controlling operational characteristics of medical equipment. A pressure sensor associated with the caregiver is arranged to sense changes in air pressure that correspond to breathing activity of the caregiver. The pressure sensor may comprise a neckband, headset, or the like. In the arrangement shown, a headset that is worn by the caregiver includes a disposable tube connected to a pressure transducer such that the pressure sensor senses changes in air pressure in the tube. An open end of the tube is positioned near the mouth of the caregiver to receive changes in airflow from the caregiver's mouth. The pressure sensor is in communication with a controller associated with the ventilator. The controller is arranged to control at least one operational parameter of the ventilator, such as the delivery of respiratory support to the patient or actuation of an oxygen flush valve on the ventilator, based upon the changes in air pressure sensed by the pressure sensor.

Abstract: A vaporizer for introducing a vapor of an anesthetic liquid into t carrier gas for introduction into a patient is disclosed. The vaporizer directly vaporizes the liquid by introducing the liquid into a vaporizing chamber having an extremely large width to height ratio, i.e. in excess of 600:1. The carrier gas flows in laminar flow through the vaporizing chamber and the liquid anesthetic is introduced at a controlled flow such that it immediately vaporizes upon introduction to the entrance of the vaporizing chamber. A control scheme utilizing a CPU controls the percentage of anesthetic vapor in the outlet gas by sensing certain parameters and then controlling the flow of liquid anesthetic by controlling the speed of a controllable speed pump.

Abstract: A breathing circuit for use with a ventilated patient that includes a heat exchanger for removing water vapor from the breathing gases to prevent condensation within the breathing circuit. The heat exchanger is positioned downstream from the CO2 absorber and receives the breathing gases from the CO2 absorber prior to delivery of the breathing gases to the inspiration limb of the patient circuit. The heat exchanger includes a plurality of inflow tubes and outflow tubes that are each open to a sump removably attached to the heat exchanger. The sump collects the water vapor condensed from the breathing gases within the heat exchanger.

Abstract: A gas flow valve having pneumatic vibration dampening device to reduce the vibrations created by the flow of gas through the gas valve. The gas valve includes a gas flow conduit that terminates at a discharge opening. A valve member is movably positioned relative to the discharge opening and allows gas flow in a flow condition and prevents the flow of gas in a seated position. The valve member includes a gas passage formed within the valve member. At least one flexible membrane is mounted to the valve member and surrounds an outlet opening of the gas passage. The flexible membrane is inflated as the flow of gas within the gas flow conduit increases such that the flexible membrane contacts an inner surface of a stabilizing conduit. The interaction between the flexible membrane and the stabilizing conduit reduces the vibrations created by the flow of gas past the valve member.

Abstract: An anesthesia system wherein the respiratory system is fitted with interchangeable patient circuit modules that allows a generic fitting in the machine to have affixed, hereto, a module that has ports suitable for connection to various patient breathing circuits. As such, the anesthesia machine can have the patient circuit modules easily changed and thus be adaptable for use with patient breathing circuits such as the circle system, the open/nonrebreathing circuit and the Bain or Mapleson D circuits. A detector system is provided that identifies that particular patient module installed in the anesthesia machine to alert the main CPU and to thus provide the correct flow sensing schemes and flows to the patient breathing circuit then being used.

Abstract: An interface mechanism is provided that removably unites a carbon dioxide absorption canister with a patient breathing circuit on a ventilator. The interface mechanism includes a cradle that is moveably positioned between a first position and a second position, wherein in the first position, the canister is coupled to the cradle and the cradle is positioned such that the canister is in fluid communication with the breathing circuit. In the second position, the canister is removable from the cradle and the cradle extends at an angle from the patient breathing circuit. The interface mechanism advantageously provides visual indication when the canister is removed and the breathing circuit is operating as a closed loop system, without CO2 filtration. The mechanism also facilitates efficient and accurate fluid connection between the carbon dioxide absorption canister and the breathing circuit.
