Abstract:
PROBLEM TO BE SOLVED: To provide a method to detect a severity change in disease conditions of respiratory insufficiency (RI) or chronic obstructive pulmonary disease (COPD) of a patient, and an apparatus and system.SOLUTION: A detection-monitor device determines one or more indicators for the severity changes based on a measurement value of supplied pressure or other representable measurement value determined by the device. The supplied pressure can be optionally determined during pressure treatment to satisfy a targeted ventilation volume. These supplied pressure or the representable data also can be compared with one or more thresholds selected to indicate the change in the condition (such as an exacerbation of the past condition) of an RI or COPD patient. The result by the comparison can generates one or more alerts or messages to inform the patient or a doctor of the urgent change in the condition of RI or COPD of the patient. The patient can ask for a medical care more quickly to treat the condition.
Abstract:
PROBLEM TO BE SOLVED: To provide a patient interface system capable of closing the airway of a patient and delivering breathable gas to the airway of a patient. SOLUTION: The patient interface system includes a patient interface structure 2000 configured to sealingly engage the patient's nostrils; a pair of strips configured to be connected to both sides of the patient interface structure; and an adhesive configured to fix the patient interface structure. Another patient interface system includes a first component including the adhesive on a first side and a hook or loop fastener material on a second side, wherein the adhesive is configured to adhere the component to the face of the patient; and a patient interface structure configured to sealingly engage with the patient's airway. The patient interface structure includes a second component including a loop or hook fastener material configured to engage with the hook or loop fastener material of the first strip to fix the patient interface structure in sealing engagement with the patient's face. The patient interface system includes nasal prongs or pillows 2002 to sealingly engage with the nostrils and a spring configured to bias the nasal prongs or pillows outward.

Abstract:
An apparatus for delivering a flow of breathable gas to a patient for the treatment of Sleep Disordered Breathing (SDB) that is less obtrusive includes a nasal cannula, cannulae (2a, 2b), prongs, or pillows and may be sealed or unsealed with the nares of the patient in use. The cannula, pillows or prongs may be positioned on the face of the patient by a headgear (6). The cannula, pillows or prongs may be smaller, lighter, and/or less visible than other nasal cannula, cannulae, pillows or prongs and may therefore be less obtrusive to the patient.
Abstract:
An interface system configured to deliver a flow of breathable gas to a patient, including a patient interface (4) comprising a frame and a cushion that is releasably mountable to the frame and a positioning and stabilising structure configured to in-use maintain the patient interface in engagement with the patient’s nares. The cushion comprises a first nasal prong and a second nasal prong. The frame includes a first arm and a second arm that extend away from each other on either side of the patient’s nose, in use the first and second arms not extending further laterally than the lateral margins of the patient’s eyes. The positioning and stabilising structure includes headgear (283) having a cradle provided by an upper strap (284) configured to extend over the top of the patient’s head and a lower strap (290) configured to engage a back of the patient’s head to thereby serve as an anchor point. The headgear includes a first side strap and a second side strap that each extend from the cradle along a respective side of the patient’s head to connect the headgear to the frame.
Abstract:
A therapy system configured to wash out or flush out the oral and/or nasal cavity to reduce the effective dead space and reduce the work of breathing. The system may displace the expired air in the oral and/or nasal cavity with atmospheric air, or air with altered concentrations, for example, increased humidity, or oxygen levels. A sealed oral interface is provided to the mouth of a patient to supply a volume of pressurized gas. A control system to synchronize the supply of pressurized gas with the patients respiratory cycle. The supply of respiratory gas may be provided during only a portion of the respiratory cycle.

Abstract:
Devices and systems provide methods of detecting a severity change in respiratory insufficiency (RI) or chronic obstructive pulmonary disease (COPD) condition of a patient. In an example embodiment, a detection monitoring device determines one or more severity change indicators based on a measure of supplied pressure or other representative measure determined by the device. The supplied pressure may optionally be determined during pressure treatment that satisfies a target ventilation. The supplied pressure or representative data may be compared to one or more thresholds that are selected to represent a change in the condition of the RI or COPD patient such as an exacerbation of a prior condition. Results of the comparisons may trigger one or more warnings or messages to notify a patient or physician of a pending change to the patient's RI or COPD condition so that the patient may more immediately seek medical attention to treat the condition. f(t) 122 120 105 Fig. 1 Deliver a respiratory pressure treatment to a patient interface with a respiratory treatment apparatus.

Abstract:
Disclosed is a method for determining the presence of mouth leak. The method is for apparatus having a blower adapted to provide a supply of breathable gas to a patient at positive pressure and a mechanism for monitoring the flow of gas in the apparatus. The method comprises the steps of: determining a measure of leak volume during inspiratory portions of respiratory cycles of the patient; determining a measure of leak volume during expiratory portions of respiratory cycles of the patient; and determining the presence of mouth leak depending on the relative values of the two respective determined measures of leak volume.
Abstract:
The present invention relates to a system for providing respiratory therapy to a patient comprising:a patient interface (108) adapted to present a respiratory gas at an entrance to a patient's airways;an air delivery conduit (106) connected to the patient interface; andapparatus to provide a controllable supply of air having a flow rate, a temperature and a humidity, the apparatus being controlled to vary at least one of flow rate, temperature and humidity,the apparatus being adapted to provide a first level of humidification during an inspiratory portion of a respiratory cycle of a patient and a second level of humidification during an expiratory portion of the respiratory cycle.
Abstract:
A method of screening for the risk of a sleep disorder such as obstructive sleep apnea proceeds by first providing a sleep health education to a member of an organization, offering and following up by providing a portable screening device for use by the member at home, which monitors a respiratory parameter such as airflow and/or oxygen saturation. The data from the monitoring is then analysed to determine the presence of the sleep disorder and the results are then reported.
