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

摘要： A bi-level positive airway pressure device includes a housing that has a patient port for connecting to an airway of a patient. Within the housing is a device that generates a positive airway pressure directed towards to patient port. Also within the housing is a system that mechanically detects exhalation (by the patient that is connected to the patient port) that enters into the patient port. Responsive to detecting exhalation, a blocking device occludes the device that generates positive airway pressure, thereby reducing or stopping the positive airway pressure until the system that mechanically detects exhalation no longer detects exhalation, at which time the blocking device is operated to no longer occlude the device for generating positive airway pressure, thereby providing positive airway pressure to the patient port during, for example, inhalation.

摘要： A manometer with a cadence indicator includes a housing and a gas pressure indicator interfaced to the housing. An input port of the housing is for connecting the manometer to a source of gas pressure, such that the gas pressure at the input port is reflected in the gas pressure indicator, providing a pressure reading. A cadence module is interfaced to the housing such that cadence is provided concurrently with the local of the gas pressure indicator in two cadence pulse frequencies, one for timing of chest compressions and one for timing of administration of breaths. Cadence is provided visually or audibly.

摘要： A breathing assistance device with improved pressure characteristics is capable of providing a high level of CPAP per unit of supplementary respirable gas consumed while maintaining low CPAP fluctuations throughout the breath cycle. The invention also includes a manometer for monitoring pressure and a safety pressure relief valve as additional safety measures 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.
