摘要： A breathing assistance device with improved pressure characteristics provides a high level of CPAP per unit of supplementary respirable gas consumed while maintaining low CPAP fluctuations throughout the breath cycle utilizing a frustrum-shaped air channel that has no unblocked openings to accelerate air flow. In some embodiments, a manometer is provided for monitoring pressure and/or a pressure relief valve is provided as a safety measure against overpressure delivered to a patient. In some embodiments, the device is disposable for one-time or single patient use.

摘要： A device for detecting a flow of respiration in a conduit includes a source of a gas jet interfaced to a side of the conduit. The source of the gas jet emits a jet of gas aimed across the conduit. A main port is interfaced to a distal side of the conduit for receiving the jet of gas and a pressure-detecting device is interfaced to the main port. In absence of the flow within the conduit, the gas jet enters the main port and the pressure-detecting device reports a first pressure. In presence of the flow within the conduit, the gas jet is deflected away from the main port by the flow and the pressure-detecting device reports a second pressure, the second pressure being lower than the first pressure.

摘要： An airway circuit has two modes of operation, dependent upon the presence or absence of a nebulizer in a nebulizer port. When the nebulizer if absent, a patient port is in fluid communications with a ventilation circuit port through a heat and humidity exchange element. When the nebulizer is inserted into the nebulizer port, the nebulizer port (and nebulizer), patient port, and ventilation circuit port are in fluid communications with each other and the heat and humidity exchange element is isolated, thereby protecting the heat and humidity exchange element from medicines emanating from the nebulizer. After the nebulizer is removed from the nebulizer port, the patient port is again placed in fluid communications with the ventilation circuit port through a heat and humidity exchange element.

摘要： An application for a disposable support/resuscitation system includes a pressurized gas inlet connected to a pressure relief device. The pressure relief device has a first pressure relief valve that opens at a setable gas pressure and, optionally, has a second pressure relief valve that opens at a pre-determined maximum gas pressure. Changing the first pressure release valve from a low pressure range to a high pressure range requires activation of a pressure range actuation button. A manometer is connected to the pressure relief valve. A manually operated valve is connected to the manometer, and a patient interface port is connected with the manually operated valve. The manually operated valve selectively controls administration of the pressurized gas to the patient. The manometer, pressure relief device, and manually operated valve are made from non-ferromagnetic materials for proper operation in the vicinity of a Magnetic Resonance Imaging System.

摘要： A swivel connector includes a patient member that has a first end for connecting to a patient facemask. The first end of the patient member is in fluid communication with a second end of the patient member. A first end of a gas supply member is for connecting to a supply of gases. A second end of the gas supply member is rotatably and fluidly coupled to the second end of the patient member, thereby gases flow between the patient member and the gas supply member. An axis of the first end of the patient member is at a non-zero angle with respect to an axis of the second end of both members. Likewise, an axis of the first end of the gas supply member is at a non-zero angle with respect to an axis of the second end of both members.

摘要： An application for a PEEP valve includes a filter media in the air flow between a patient interface and exit vent(s). The patient interface is connected to a patient airway system and the exit vents exhaust exhalation gasses into the atmosphere. The filter prevents or reduces the passage of microbes from the patient's exhalation gasses into the atmosphere. The PEEP valve provides positive gas pressure to a patient's lungs, requiring a predetermined exhalation gas pressure to be exceeded before releasing exhalation gasses into the atmosphere.

摘要： An application for a neonatal calorimetric carbon dioxide detector has a calorimetric carbon dioxide detector membrane having a pH-sensitive chemical indicator that undergoes calorimetric change in the presence of carbon dioxide. The detector has a patient orifice in fluid communication with the baby's airway and a respiration equipment orifice connected to a breathing system. The patient orifice is connected to a breathing tube and when the breathing tube is inserted correctly into the trachea, as the baby exhales, carbon dioxide interacts with the calorimetric membrane which changes color based upon the concentration of carbon dioxide. The neonatal calorimetric carbon dioxide detector adds a volume of less than or equal to 1 mL after being attached to a breathing circuit.
