Abstract:
Patient interface (50) optically indicating a user that a member (22) of the patient interface (50) needs to be replaced due to wear. In particular, it relates to a member (22) for patient interface (50) which comprises at least one functional material (32, 34) having a predefined functionality and at least one indicator (28, 30) wherein the concentration of said at least one indicator (28, 30) in said member (22) correlates with the predefined functionality of said at least one functional material (32, 34).
Abstract:
A power supply system comprises a fuel cell and a battery, each for supplying electrical power to a load. The system is controlled to use the fuel cell for a first period of time (82) to supply electrical power to the load, wherein the power demand is constant over a first time period (82). The battery is used simultaneously with the fuel cell for a second supply time of electrical power to the load, wherein the power varies (84). In this way, fluctuating output is provided by the battery, and the fuel cell output is maintained as constant as possible to prolong the lifetime. During the second supply time, the power to the load (80) can be provided as a constant contribution from the fuel cell and a variable contribution from the battery.
Abstract:
The present disclosure pertains to a system for facilitating configuration modifications for a patient interface computer system based on an equivalent effort parameter. In some embodiments, the system obtains (i) one or more first measurements associated with a first subject, the first subject having a clinical coefficient, (ii) one or more second measurements associated with a second subject. The system determines (i) a first effort parameter based on the one or more first measurements, (ii) a second effort parameter based on the one or more second measurements, and (iii) an equivalent effort factor for the first subject based on the one or more first measurements, the one or more second measurements, and the clinical coefficient. The system causes a configuration of the patient interface computer system to be modified based on the equivalent effort factor.
Abstract:
Various improvements are provided to breathing training, monitoring and/or assistance devices. A portable device is provided which optionally includes a gas canister, a feedback system for implementing pressure control, and a visual output for indicating adherence to a breathing exercise to the user. The pressure control may provide regulation of different pressures for inhalation and exhalation.
Abstract:
An apparatus for creating a flow of gas comprises a frame having a passage defined therethrough. The passage extends a length along a central longitudinal axis from an inlet to an outlet and has a first side and a second side. A flexible pumping membrane is disposed within the passage. The membrane has a first edge coupled to the first side of the passage at a midline thereof and a second edge, disposed opposite the first edge, coupled to the second side of the passage at a midline thereof. The membrane segregates the frame into an upper portion and a lower portion. The apparatus also includes an actuating system which is structured to selectively move portions of the membrane toward either the upper portion or the lower portion of the frame in a manner which causes a wave-like movement in the pumping membrane and creates the flow of gas.
Abstract:
An apparatus comprises an activity monitor for measuring physical activity of a subject. The activity monitor is configured to obtain a first set of physical activity data over a first time period, for example during the day, and a second set of physical activity data over a second time period, for example during the night. A processor processes the data obtained by the activity monitor to calculate a physical activity ratio which is the ratio of the physical activity measured during the first time period to the physical activity measured in the second time period. The processor also calculates a first overall value which represents an activity level of the subject during the first time period. The physical activity ratio together with the first overall value may be used to assess the severity of symptoms of COPD displayed by a subject or to identify respiratory disease comorbidity information for example psychological issues such as low motivation, or sleep quality issues displayed by the subject.

Abstract:
The present invention relates to an apparatus, a system (100), a method (200), and a computer program for assessing the risk of an exacerbation and/or hospitalization. A patient's physical activity is measured (e.g., by an accelerometer (110)) during an active period of time (e.g., during awake hours) and during a rest period of time (e.g., during sleep hours) to gather first and second activity data. A risk of exacerbation and/or hospitalization is assessed (e.g., by a risk assessment unit (120)) based on an expression involving the respective activity data during active and rest periods fulfilling a predetermined relationship with respect to a predetermined activity level. For instance, low activity data during active periods and high activity data during rest periods indicates an increased risk of exacerbation and/or hospital readmission for the patient.
Abstract:
The present invention relates to a system for monitoring asthma symptoms of a subject (12), comprising a monitoring unit (14) configured to monitor at least one objective asthma symptom of the subject, an analysis unit (16) configured to determine an asthma status of the subject based on the at least one objective asthma symptom monitored by the monitoring unit, a test unit (18) configured to provide a test for collecting subjective asthma symptoms from the subject, if the at least one objective asthma symptom monitored by the monitoring unit (14) has changed in a manner that the change reveals a deterioration of the asthma status of the subject. Further the system comprises a calibration unit (24) configured to calibrate the at least one objective asthma symptom gathered from the subject with respect to a calibration test, wherein the calibration unit (24) is arranged to perform calibration at least once during an initial phase of use of the system (10).
Abstract:
Chronic obstructive pulmonary disease (COPD) is one of the growing chronic respiratory diseases and is now a major cause of morbidity and mortality. Acute exacerbations have a negative impact on health related quality of life of COPD patients, survival rates, pulmonary function and utilization of health-care resources. The present application discloses an apparatus (100), system (1400), method (200), and computer program for assessing a risk of an exacerbation and/or hospitalization of a subject. To this extent, time-dependent activity data is Fourier-transformed to frequency space to obtain frequency-dependent activity data. Next, a moment of said frequency-dependent activity data is computed. Finally, a risk of said exacerbation and/or hospitalization of said subject to occur is assessed based on said moment.
