A bi-level positive airway pressure device includes a housing that has a patient port for connecting to an airway of a patient. There is a device (e.g., a nozzle) for generating a positive airway pressure that is directed through a conduit towards the patient port. An exhalation detector includes a nozzle emitting a jet of a gas directed across the conduit and directed at a receptor channel when exhalation gases flow from the patient port, thereby an increase a gas pressure is present at the receptor channel when the exhalation gases flow from the patient port. The exhalation detector converts the increase in the gas pressure into a movement of an occluding member such that when the exhalation gases flow from the patient port, the occluding member moves to block the means for generating the positive airway pressure.

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.

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 detects exhalation (by a 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 generated positive airway pressure, thereby reducing or stopping the positive airway pressure. Upon the system detects abatement of exhalation, 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.
A breathing assistance device includes a patient breathing tube having a leading end in fluid communication with a face mask. A source of air under pressure is connected to a first port formed integrally with a valve in fluid communication with the breathing tube and a nebulizer is connected to a second port formed integrally with the valve. A compartment holding a medicinal compound in liquid fluid form is connected to the nebulizer. A valve actuator has an open position where gaseous fluid and aerosolized medicine from the nebulizer flow to the patient through the breathing tube and a closed position where only gaseous fluid without medication is delivered. Medication can therefore be administered to or withheld from the patient by manipulating the valve actuator. The valve construction enables the patient to exhale against pressure slightly above atmospheric pressure.

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.

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.

An oral cannula for delivering oxygen and sampling end-tidal carbon dioxide includes an oxygen supply lumen having plural outlets and an end-tidal carbon dioxide (ETCO2) lumen having an inlet. The ETCO2 lumen and oxygen supply lumen form a unitary oral cannula such that the oxygen supply lumen outlet is spaced apart from the ETCO2 lumen inlet. The oral cannula is adapted for bending or has a bend such that the oral cannula is insertable and retainable in a patient's mouth.
A breathing assistance device with improved pressure characteristics is disclosed. The device 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 further optionally comprises a manometer for monitoring pressure and a safety pressure relief valve as additional safety measures against overpressure delivered to a patient. The device may be made to be completely disposable for one-time or single patient use.
A disposable manometer includes a chamber connectable to a source of respiratory gases via a patient breathing valve and a passageway. A pointer is rotatably disposed with respect to a dial to indicate pressure within the chamber. The pointer has an actuator stem with a spiral-shaped protrusion coupled to a groove within an opening of a stem coupling attached at the center of a diaphragm forming one wall of the chamber. Responsive to pressure entering the chamber, the diaphragm reciprocates against the force of a biasing non-magnetic resilient member moving the stem coupling with respect to the actuator stem of the pointer so that the interaction between the spiral-shaped protrusion and the groove causes rotation of the pointer to indicate the pressure within the chamber. The disposable manometer is useful with any source of respiratory gasses and in the vicinity of any strong magnetic field.

A neonatal colorimetric carbon dioxide detector has a colorimetric carbon dioxide detector membrane having a pH-sensitive chemical indicator that undergoes colorimetric 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 colorimetric membrane which changes color based upon the concentration of carbon dioxide. The internal volume of the neonatal colorimetric carbon dioxide detector is reduced to properly function with low-birth-weight (neonatal) infants.
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.
