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.

Apparatus for humidifying a respiratory gas

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 present application is directed to a detector to detect or generate measuring signals that are indicative of the respiration of a person, wherein said detector can be used advantageously in view of hygiene and stands out due to a simple and robust configuration. According to a first aspect, the detector detects a signal that is indicative of the activity of the respiratory muscles of a person to be examined, the detector comprising a band which, in the application position, is passed around a torso region which widens and narrows when the person to be examined breathes, as well as a structure that is included in the band and loaded in accordance with the narrowing or widening of the torso region. The structure is configured such that it causes a change in the volume of a measuring space device depending on a tensile force. It is thus advantageously possible to detect or measure the forces acting on the band in a non-electric manner and, on the basis of this detection or measurement, draw conclusions relating to the widening or narrowing of the torso.

Respiration detecting arrangement

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.

Respiration detecting means

Apparatus for humidifying a respiratory gas includes a liquid storage space for storage of a liquid, a humidifying region for loading the respiratory gas with the liquid by the respiratory gas coming into contact in the humidifying region with the liquid, a respiratory gas supply device for supplying the respiratory gas to the humidifying region, a respiratory gas withdrawal device for withdrawal of the humidified respiratory gas from the humidifying region, and a partial-amount discharge device for passing a partial amount of the liquid stored in the liquid storage space into the humidifying region.

The invention relates to a device for supplying a respiratory gas to a patient within the scope of the diagnosis and/or the treatment of sleep-related breathing disorders. The invention especially relates to a CPAP appliance comprising self-optimising dual level pressure regulation. According to the invention, the device for supplying a respiratory gas comprises an electronic signal processing device for generating a pressure control signal (p) on the basis of indicative signals () relating to the breathing activity and/or the physiological state of a person. The signal processing device () comprises a signal inputting device and an extraction device () for generating data field entries () according to predefined signal analysis procedures. A pressure signal generator () is provided for generating the pressure control signal (p), taking into account determined data field entries () which are at least selected by the extraction device ().
