A humidifier assembly for a CPAP includes a base housing with a gas inlet configured to receive respiratory gas from the CPAP unit. The base housing includes a first connecting device located at a sidewall of the base housing and configured to directly, removably connect the base housing to the CPAP unit. The base housing also includes a second connecting device configured to be coupled to an air delivery hose. The humidifier assembly further includes a liquid storage container that is removably received in the base housing. The liquid storage container includes a liquid storage space configured to store liquid and a humidifying region configured to receive the respiratory gas from the gas feed opening and receive a partial amount of the liquid stored in the liquid storage space to enrich the respiratory gas with moisture.

Apparatus for humidifying a respiratory gas

An apparatus for delivering pressurized, humidified breathable gas to a patient having a sleep-related disorder includes a CPAP unit with a blower configured to generate a flow of pressurized breathable gas. The Apparatus also includes a liquid storage container configured to hold a body of liquid. The liquid storage container has a gas feed opening, a gas discharge opening and a humidifying region above a metallic heat conducting material. In addition, the apparatus includes a support housing integrated directly into the CPAP unit and having a receiving space configured to removably receive the liquid storage container. The liquid storage container is structured such that when the liquid storage container is received by the support housing, the gas feed opening aligns with and engages with an ending portion of a gas feed flow path defined by the support structure and the gas discharge opening aligns with and engages with a beginning portion of a gas discharge flow path defined by the support structure so that the liquid storage container fluidly connects the gas feed flow path and the gas discharge flow path.

A positive pressure gas supply system configured to supply positive pressure gas to a patient includes a CPAP unit configured to generate a flow of positive pressure gas. A humidifier base is positioned to receive the flow of positive pressure gas from the CPAP unit. A receiving portion of the humidifier base is configured to removably receive a refilling module. The refilling module is configured to hold a volume of water, complete a gas flow path partially defined by the humidifier base, and humidify the positive pressure gas. In addition, a respiration tube connecting portion is positioned to remain in communication with a gas discharge passage of the humidifier base when the refilling module is removed from the humidifier base. The respiration tube connecting portion is configured to be connected to a respiration tube and deliver the humidified positive pressure gas to the respiration tube.

A humidifier assembly for a CPAP apparatus includes a liquid storage container configured to hold a body of liquid. The liquid storage container includes a humidifying region above a metallic heat conducting material, the humidifying region being a region inside the liquid storage container in which the liquid is evaporated into pressurized respiratory gas generated in the CPAP apparatus. The humidifier assembly further includes a base unit configured to a) receive the liquid storage container and b) connect to a CPAP unit of the CPAP apparatus. The base unit includes a housing providing a base portion to support the liquid storage container thereon, the base portion including a heating element configured to contact the heat conducting material of the liquid storage container when the liquid storage container is supported on the base unit. The base unit also includes an inlet configured to receive and be coupled to an outlet of the CPAP unit. In addition, the liquid storage container is removable from the base unit.

When the liquid storage container is received by the base unit, the liquid storage container and the base unit together define an airflow path through the humidifier assembly, an inlet of the airflow path being upstream of the liquid storage container and an outlet of the airflow path being downstream of the liquid storage container.

The invention concerns an apparatus for supplying a respiratory gas, a humidifying apparatus, a respiratory gas tube and a connecting apparatus therefor. The apparatus of the invention includes a blowing device for delivering the respiratory gas, a housing device which has a bottom region, a top surface region and a side region extending upwardly between the top surface region and the cover region, as well as a connecting device for connecting a humidifying apparatus for humidifying the respiratory gas, wherein the connecting device is arranged in the side region of the apparatus in such a way that the humidifying apparatus can be laterally coupled thereto. The humidifying apparatus according to the invention is distinguished by a partial amount discharge device for passing a partial amount of the liquid pre-stored in a liquid storage space into a humidifying region. The respiration tube according to the invention includes a connecting plug structure which has both a respiratory gas connecting portion and also a pressure measuring tube connecting portion.

A device for detecting electrical potentials in the forehead area of a patient has a transverse member adapted to rest against the forehead of the patient, a vertical member extending crosswise to the transverse member and a mask on the vertical member. Electrodes are provided on the transverse members at least at its ends and at the center at which the vertical bar crosses the transverse member.

The invention relates to a device for assessing the applied air pressure during automatic respiration through positive airway pressure. The air pressure applied is varied by the device according to the invention so that at least three different pressure values can be adjusted. The corresponding respiratory gas flow is measured. On the basis of the relation of the measured respiratory gas flows to each other it is determined whether the applied air pressure is below or above an optimal air pressure or whether the applied air pressure is the optimal air pressure. The device according to the invention can be applied for adjusting the optimal air pressure in respirators used in the CPAP therapy. The device according to the invention provides the advantage of enabling an easy and reliable control of the applied air pressure.
