Abstract: A nebulizer comprises a head detachably coupled to a body. The head comprises nebulizing means, an air channel and a flow sensor. A nebulized liquid is released in an air channel that ends in a mouth piece through which a user inhales and exhales. The inhaling and exhaling causes a flow in the air channel which is detected with the flow sensor. The nebulizing means are controlled by control means included in the body.

Abstract: A patient interface device uses a pressure flap which extends inwardly from an outer edge of a mask of the device. The pressure flap is for contacting the skin of the patient to provide a seal or partial seal between the mask volume and the ambient surroundings. The pressure flap comprises a cavity area which is exposed to a reduced pressure compared to the mask volume. This assists in keeping the pressure flap pressed against the patient's skin, and thereby maintain a large contact area. This in turn gives a reduction in local high pressure areas.

Abstract: The present invention relates to a patient interface and a patient interface system comprising a responsive material and a method for preventing the formation of red marks due to wearing a patient interface (10) that is pressing against the skin of a patient (14) for a longer time and/or for reducing air leakages of the patient interface (10) that may result from an unintended shift of the patient interface (10) on the patient's face. The responsive material is configured for alternating the pressure exerted by the cushion element (18, 26) on the patient (14), and/or the area on the patient where the pressure is exerted by the cushion element in response to a physical quantity acting on the responsive material. The formation of red marks and of air leakages can be reduced or even avoided by means of the responsive material.

Abstract: The present invention relates to a detector, a patient interface and a patient interface system comprising this detector, and a method for preventing the formation of red marks due to the wearing of a patient interface (12) that is pressing against the skin of the patient (18) for a longer time. With the detector and via the method, the blood flow and/or the occlusion of the blood vessels of the patient (18) are monitored, and the assessed degrees are used as a basis to adjust the patient interface (12) in order to reduce the force pressing against the skin of the patient (18), such that the formation of red marks is prevented.

Abstract: The invention relates to a system (102) for measuring a velocity of a fluid (104) flowing through a flow channel (106). The system comprises a heating element (108) configured for generating a thermal marker in the fluid (104) in response to a predetermined time-varying level of power provided to the heating element (108). The system (102) furthermore comprises a sensor arrangement (110) for generating a measurement signal (112) indicative for the velocity of the fluid (104) flowing through the channel (106). Herein, the sensor arrangement (110) is configured for measuring a time series of the primary temperature (114) of the fluid (104) at a predetermined primary location. The primary location and the heating element (108) are situated on an axis having at least a component parallel to the longitudinal axis (119) of the flow channel (106). The measurement signal (112) is based on the maximum value (120) of the time series of time series of the primary temperature (114) in response to the thermal marker.

Abstract: An aerosol delivery system (e.g., MDI or nebulizer for delivering aerosolized medication to a patient) includes a temperature sensor (10) in an aerosol output pathway of the system. A controller (600) determines that an aerosol generator of the system has released aerosol when the sensor senses a predetermined temperature change in the pathway. The temperature sensor may also comprise a thermal flow sensor that includes a heater and upstream and downstream temperature sensors. The controller compares the upstream and downstream temperatures to determine the presence, direction, and/or magnitude of fluid flow in the pathway. The controller may use the aerosol detection and/or flow detection to monitor compliance with desired use of the system and/or provide real-time instructions to a user for proper use of the system. The controller may record the aerosolization and flow data for later analysis.

Abstract: The present invention relates to determining or measuring a biological, physical or physiological parameter of an object (10) by a sensor (2). It may be beneficial to constantly monitor or determine a biological, physical or physiological parameter of an object (10) by a sensor (2), subsequently allowing for a preferred removal of the sensor (2) from object (10) when the monitoring is no longer required. Accordingly, a sensor (2) is provided, e.g. a flow sensor, employing a degradable adhesive (8) for attachment of the sensor (2) to the object (10). The degradable adhesive (8) may be degradable e.g. by time, by exposure to a certain measure, e.g. induced heat, or substance for detaching the sensor (2) from the object (10) for subsequent removal of the sensor (2).
