A moisture removal apparatus for a breathing circuit may include a breathing gas conduit configured to receive a flow of breathing gas having a first humidity level. The apparatus may include a dry gas conduit adjacent to at least a portion of the breathing gas conduit, the dry gas conduit configured to receive a flow of dry gas having a second humidity level lower than the first humidity level. The apparatus may also include a feeding conduit extending through at least a portion of the dry gas conduit, the feeding conduit configured to introduce the dry gas into the dry gas conduit. The apparatus may further include a moisture transmission pathway configured to enable transfer of moisture from the breathing gas to the dry gas based on the humidity differential.

Moisture removal and condensation and humidity management apparatus for a breathing circuit

A respiratory filter and condensate management apparatus is provided for use in a breathing circuit during patient respiration. The apparatus includes a filter housing having an air inlet port and an air outlet port. A filter member is provided within the filter housing and located in an expiratory air flow path. A collection jar is removably attached to the filter housing and has a liquid reservoir to collect liquid formed by condensation in the flow of expiratory air within the filter housing when the collection jar is attached to the filter housing. A valve assembly moves to an open position when the filter housing is attached to the collection jar to allow drainage of the liquid from the filter housing. The valve assembly moves to a closed position when the filter housing is detached from the collection jar to prevent drainage of the liquid from the filter housing.

A nebulizer is provided to atomize a liquid medication for rapid delivery of an aerosol spray to a user via inhalation. The nebulizer includes a jar having a compressed gas passage. A jet cooperates with the jar and has a jet orifice through which the liquid medication and the compressed gas are discharged to form an aerosol flow. The cap is connected to the jar to define an inner chamber. The cap includes an entrainment port for ambient room air, and a chimney in fluid communication with the entrainment port and the inner chamber. A deflector base having an impingement member is located adjacent to the entrainment chimney and is spaced below an opening thereof by a predetermined distance to provide a flow of the ambient room air to be entrained in the aerosol flow in order to enhance nebulization speed while maintaining a desired aerosol particle size.

A near-patient humidification system provides vapor to a respiratory breathing circuit. The system includes an expiratory gas conduit and an inspiratory gas conduit. A patient coupling member is provided for coupling the expiratory and inspiratory gas conduits to a patient interface. A vapor injection unit is located at least partially within the housing of the patient coupling member. The vapor injection unit heats a supply of fluid into vapor and injects the vapor into the inspiratory gas passage of the patient coupling member at a vapor injection location for providing moisture to the inspiratory gas flow. A method of simultaneously and independently controlling the temperature and humidity of inspiratory gas in a respiratory breathing circuit is performed by injecting vapor having a temperature determined as a function of measured temperatures and measured humidities of the breathing gas at different locations along the breathing circuit.

System and method for on-demand near-patient humidification

An endotracheal tube holder device is provided for securely holding an endotracheal tube to a patient during intubation. The tube holder device includes a support rail placed above a lip of a patient. An auxiliary clip is coupled to the support rail and slidably movable along the length of the support rail for holding an accessory device relative to the patients face. The auxiliary clip includes both a horizontal accessory clip and a vertical accessory clip to releasably retain the accessory device horizontally and vertically, respectively. A tube fastener is coupled to the support rail and includes a tube holder base, an adjustment clip coupled to the tube bolder base for laterally repositioning the tube holder base along the support rail, and a securement tie. The securement tie may be wrapped around a portion of the endotracheal tube to secure the tube to the tube holder base.

A moisture removal and condensation and humidity management apparatus for a breathing circuit includes a breathing circuit tubing defining a breathing gas conduit. The breathing gas has a first humidity level and a level of moisture therein. A dry gas conduit is adjacent at least a portion of the breathing gas conduit. The dry gas flow is configured to have a second humidity level lower than the first humidity level. A moisture transmission pathway is provided between the breathing gas conduit and the dry gas conduit, such that humidity in the flow of breathing gas is lowered and moisture is transferred to the dry gas flow. The moisture transmission pathway may be provided by a permeable portion which is permeable to water vapor but impermeable to liquid water, or by one or more perforations which permit drainage of liquid water from the breathing gas conduit to the dry gas conduit.

A dry gas conduit is provided adjacent to at least a portion of the breathing gas conduit for receiving a flow of dry gas having a second humidity level lower than the first humidity level. A heating element extends from an upstream end of the breathing gas conduit to a downstream end of the breathing gas conduit. The heating element provides heat to the flow of breathing gas such that the breathing gas at the downstream end is heated to a higher temperature than the breathing gas at the upstream end. A moisture transmission pathway enables transfer of moisture from the breathing gas to the dry gas based on the humidity differential.

A respiratory mask for a medical patient including a shell and a flow coupling is disclosed. The shell includes an upper portion configured to cover a nose of the patient and a lower portion configured to cover a mouth of the patient, where an internal surface of the shell defines an interior volume of the respiratory mask. The flow coupling includes a body, a supply flow passage extending through the flow coupling, a scavenging flow passage extending through the flow coupling, and a septum within the body that separates the supply flow passage from the scavenging flow passage. The supply flow passage and the scavenging flow passage are fluidly coupled to an aperture that extends through the upper portion of the shell, and an aperture extending through the lower portion of the shell, respectively.

The present invention provides in some embodiments, an endotracheal tube with subglottic secretion suction and a detachable suction line. The endotracheal tube is an elongate tube having an outer wall defining an elongate central lumen and an elongate suction lumen. An inflatable cuff is attached near a distal end of the elongate tube. The shoulder of the inflatable cuff is inverted in order to increase the diameter of the cuff from its distal end to its proximal end. The endotracheal tube also includes a connector to couple the suction lumen to a source of suction to remove subglottic secretions from the area above the cuff.
