Definitions
- certain respiratory diseases can be recognized and monitored. For example, by determining the nitrogen monoxide concentration in exhaled air, a measure of the inflammation of the lungs in asthma can be estimated.
- the nitrogen monoxide concentration can be determined using a device disclosed in EP 1384069 B1.
- the invention relates to a method for analyzing breathing air with a device for analyzing the breathing air, wherein at least one measured value of the breathing air is recorded with the device.
- breathing air generally means a gas or gas mixture that can be inhaled or exhaled by a user of the device, in particular air.
- the method can be used to analyze exhaled air, that is to say gas exhaled by the user, also referred to as breathing gas.
- the device can in particular be a device described above according to EP 1384069 B1.
- the method can be used to determine an amount or concentration of one or more analytes in the exhaled air, in particular a measurement of one or more analytes in exhaled air, for example of nitrogen monoxide.
- a nitrogen monoxide concentration in the exhaled air is also referred to for short as the FeNO value (“fraction of exhaled nitric oxide”).
- the measured value can therefore in particular be the FeNO value.
- the method presented is based on the knowledge that external conditions can have effects on such a measurement, in particular negative effects.
- External conditions hereinafter referred to as environmental conditions
- environmental conditions are to be understood in principle as factors outside the device which act on the device and / or on the user of the device.
- the accuracy, reliability and thus also the informative value of such a measurement can be significantly dependent on environmental conditions to which the device and / or the user are exposed.
- Ambient conditions are to be understood as meaning, in particular, air humidity, air pressure, temperature and components, for example particles such as dust or pollen or gases, of the air surrounding the user.
- brightness or volume can also be understood as brightness or volume.
- this or other environmental conditions in particular are therefore changed as a function of a value of an environmental condition.
- This advantageously enables a more well-defined, more accurate, less disturbed measurement.
- such environmental conditions can advantageously be changed or their influence on the device or the user reduced which adversely affect the functioning of the device or the user.
- a change in the environmental conditions can take place in particular by activating devices or changing the activation of devices that can influence the environmental conditions.
- devices for regulating a room climate can be controlled in such a way that the room climate, i.e. in particular the temperature,
- a cleaning unit in particular a vacuum cleaner or an air cleaning device, for example an air filter, an air conditioning system, an air humidifier and / or automatically openable doors or windows can be controlled to change the ambient conditions.
- the invention thus advantageously enables a change and improvement of the environmental conditions in a room or building, in particular within a living space of a user.
- the device can be controlled directly via the device with the aid of an in particular wireless communication interface to the devices.
- the device for breathing gas analysis can be integrated into a smart home system.
- a smart home system is to be understood as meaning, in particular, a number of networked devices in rooms, in particular in living rooms, it being possible for the networked devices to be controlled via an interface of the system and / or by the system.
- This includes, in particular, the networking of building technology or household appliances (for example air conditioning systems, air humidifiers, cleaning devices such as Vacuum cleaners, light sources, blinds, automatically opening windows or doors, heating, stove, refrigerator and / or washing machine), preferably, but not necessarily, the networking of entertainment electronics components (e.g. the central storage and home-wide use of video and audio content ).
- one or more of these parts of the smart home system can advantageously be controlled to change the ambient conditions. This has the advantage that an already available infrastructure of the smart home system can be used in a simple and effective manner for changing the environmental condition (s).
- the activation of the smart home system comprises a re-prioritization of activations of the smart home system, in particular an overriding of a second activation.
- the preferred control according to the invention can be assigned a priority with respect to the priorities of the smart home system.
- the preferred control according to the invention can be given such a high priority that is higher than the priorities of other specified controls, so that this control always has priority over the other specified controls.
- the preferred control according to the invention can be assigned the highest possible priority.
- a change in the environmental condition can also include a notification to a user of the device. This message can then advantageously cause the user to change one or more of the ambient conditions, in particular by activating the devices that can influence these ambient conditions.
- one or more ambient conditions can be controlled via sensors of the device and / or sensors from other devices are detected, for example by sensors of the devices, which can influence the ambient conditions.
- one or more values of one or more environmental conditions are recorded via the smart home system. This can be done, for example, by querying
- the smart home system can comprise one or more sensors for measuring the ambient conditions, for example for measuring air humidity, temperature and / or particles.
- the detection and the change in the ambient conditions can thus be controlled via the smart home system.
- the one or more environmental conditions are changed as a function of the measured value recorded with the device.
- This has the advantage that a change in the environmental conditions can be made dependent on which measured values occur, which advantageously accelerates the method overall and saves resources.
- a change can preferably only take place if the recorded measured value is greater or less than a predefined threshold value.
- the threshold value can for example be based on the FeNO level of a user, in particular correlate with the FeNO level of a user, for example be proportional to the FeNO level.
- An FeNO level is to be understood as an NO concentration in exhaled air that a user typically has.
- the change in the environmental condition (s) can only be initiated if the measured value is higher than the FeNO level by at least a predetermined factor, for example 20%.
- the environmental conditions are changed as a function of updateable user-specific data. This is based on the knowledge that the environmental conditions have different effects on different measuring ranges can. In particular when measuring FeNO values, different users can have different typical values, i.e. different FeNO levels. With different FeNO levels, changes in the ambient conditions therefore have different effects on the measurements. This further development thus enables a user-adapted change in the environmental conditions.
- the environmental conditions are changed as a function of environmental data.
- These environmental data can in particular be weather data or weather conditions. This advantageously enables a day-dependent adaptation of the ambient conditions.
- the device after a change in the ambient conditions, at least one further measured value of the breathing air is recorded with the device, preferably after a predetermined minimum period has elapsed.
- the user can preferably be requested by the device, for example via a display or an app on a smartphone or computer adapted to the device, to carry out a further measurement, in particular after a predetermined minimum period after a change in the ambient conditions, for example after an hour or even after one or more days, depending on the respective environmental conditions, in order to take into account a possible delayed effect of the change in the environmental conditions.
- the request is made if, when the environmental conditions are detected again, it is determined that an intended change in the environmental condition (s) has occurred.
- the invention also relates to a device for analyzing the breathing air, the device being set up to record at least one measured value of the breathing air and depending on a value of an ambient condition and preferably to transmit a control for changing one or more environmental conditions to the measured value via an interface.
- the device can in particular be based on the device disclosed in EP 1384069 B1 and have a configurable computer or processor for operating the method according to the invention.
- the device can have a communication interface for receiving data on the ambient conditions, which can be designed as a common interface with the control interface.
- the invention also relates to a smart home system, the smart home system being set up to carry out the method according to the invention.
- the smart home system can have a configurable computer or processor for operating the method according to the invention.
- the smart home system can be set up via a
- the Communication interface to receive data on the ambient conditions and, depending on this data and preferably depending on a measured value obtained from the device, to control one or more devices of the smart home system for a change in the one or more ambient conditions.
- the device for analyzing the breathing air can thus be integrated or embedded in the smart home system and therefore also form part of the smart home system.
- the smart home system can include the device according to the invention and thus preferably be set up to carry out the method according to the invention.
- the invention also relates to a computer program which, when executed on a computer, in particular when executed by the device according to the invention or by the smart home system according to the invention, causes it to execute the operating method according to the invention.
- the computer program can be stored at least temporarily on a machine-readable data carrier.
- FIG 1 shows an embodiment of the device according to the invention and the system according to the invention
- FIG. 2 shows a flow diagram of an exemplary embodiment of the method according to the invention
- Figures 1 and 2 show an embodiment of the method 600 according to the invention as well as the device 100 according to the invention and the system 1000 according to the invention.
- Figure 1 shows schematically the device 100 and the system 1000 and their interaction, while Figure 2 comprises a flowchart of an embodiment of the method 600.
- the device 100 is a device for analyzing the breathing air, or breathing gas analyzer 100 for short, which is based, for example, on the device according to EP 1384069 B1 and which is integrated into a smart home system 1000.
- the breathing gas analysis device 100 can communicate with a control device 1001 of the smart home system 1000 via a wireless interface 101 (for example Bluetooth® or WLAN).
- Conventional devices 1002 such as, for example, smartphones or tablet computers can serve as the control unit 1002 of the smart home system 1000.
- Information can also be returned to the user via this control unit 1002, in particular via a display or a loudspeaker.
- Measured values acquired via the respiratory gas analyzer 100 are transmitted in a first step 601 to the control unit 1001 via the wireless interface 101.
- the control device 1001 can then in a second step 602, for example, on request, receive data from other components of the smart home system, in particular status information. Alternatively, it can also receive this data before, at the same time or afterwards.
- the other components can in particular be household appliances such as cleaning devices, for example vacuum cleaners, air conditioning systems, air humidifiers and / or integrated building services such as heating, automatic windows or door openers, automatic blinds.
- the smart home system includes, for example, a vacuum cleaner 1010, a room air conditioning system (air conditioning) 1020 with a humidifier and air filter and a window 1030 that can be closed by remote control , a temperature and a particle load, in particular a pollen load, for example via an interface to an external information source.
- the external information source can be, for example, an external database 200 with weather and weather data. If the control unit 1002 is a smartphone or a computer, external data on ambient conditions can also be introduced into the smart home system 1000 via this, in particular via the Internet, for example via a pollen alarm app.
- the smart home system 1000 can also have its own sensors for measuring one or more environmental data, for example for measuring an air pressure or the other environmental conditions mentioned above.
- these sensors 1011, 1021, 1022 can be at least partially integrated in the components 1010, 1020, 1030.
- the air conditioning system 1020 can have sensors for measuring the air humidity, the particle load, in particular the pollen load, the temperature or the air pressure.
- the device 100 can also transmit further data, in particular data associated with the measurement, to the smart home system 1000, on which a change in the ambient conditions is made dependent.
- data associated with the measurement can be adapted as a function of this data. For example, it can this involves individual data of the user using the device 100. If, for example, the user has a generally higher FeNO level than an average FeNO level, measures to improve the air, in particular cleaning or filtering or closing doors or windows, can only be initiated when the increased FeNO values are measured, for example when the FeNO value is exceeded by 70 ppb.
- the data on the ambient conditions can preferably also include data on the infrastructure to which the smart home system is assigned.
- a room climate is also influenced by the condition of the infrastructure, in particular by the cleanliness of the infrastructure.
- the data can therefore also include data on the purity, for example the time and extent of a last ventilation of the room or a last cleaning of, for example, floors, carpets, beds, furniture, which can advantageously be taken into account in a control of cleaning devices 1010.
- This data on the infrastructure can be obtained from data from previous controls of the smart home system. As an alternative or in addition, such data can also be entered by the user, for example via an app of the control system 1002.
- one or more ambient conditions are changed in a third step 603.
- the environmental conditions can be modified in such a way that an improved and more reliable measurement can be made by the device 100.
- the smart home system 1000 can preferably be set up in such a way that controls based on measured values of the device 100 change a prioritization of control commands in the smart home system.
- controls of the smart home system can be re-prioritized.
- controls based on measured values of device 100 can have a high priority or even the highest Priority can be assigned so that other, potentially conflicting controls are overruled.
- the change in the ambient conditions can take place via an implementation of an instruction to the user, in particular by the control unit 1002, in which the user is used to change the ambient conditions, for example by operating a household appliance, for example a humidifier 1020 to increase the air humidity, or by Closing a window 1030 to reduce particulate or pollen exposure.
- the smart home system 1000 can also control one or more of its components 1010, 1020, 1030 to change the ambient conditions, for example to reduce the particle or pollen load by controlling an air filter 1020 or by automatically closing a window 1030 or a door to reduce.
- Whether and how an environmental condition is to be changed can also be made dependent on data from the previous operation of the smart home system 1000.
- a cleaning device in particular a vacuum cleaner 1010, can be activated for cleaning if the last cleaning carried out was more than a predeterminable minimum period of time and a determined particle or pollen concentration is greater than a predeterminable threshold value.
- a change in environmental conditions can be initiated by the method 600 according to the invention in particular when measured values recorded via the device 100 are in a predetermined range, for example higher than a predetermined threshold value, for example higher than 60 ppb (parts-per-billion).
- a predetermined threshold value for example higher than 60 ppb (parts-per-billion).
- the FeNO value is increased, it is possible to close open windows or doors, to clean the air from particles or pollen via the air filter and / or to clean it with a vacuum cleaner, in particular controlled via the smart home system 1000.
- the closing of open windows or doors can already be initiated if there is an increase in the external data described above Particulate or pollen exposure is imminent.
- the air humidifier can be activated when a relative air humidity falls below a predetermined value, for example below 35%, in order to increase the air humidity to an optimal value, for example to 55%.
- environmental conditions can be changed if one or more measured values are not in an expected or predetermined range, for example are above or below an expected level.
- the user is preferably requested by the device, for example via a display or an app adapted to the device on a smartphone or computer, to carry out a further measurement, for example after a predetermined minimum period has elapsed after the ambient conditions have changed, for example after an hour or after one or more days depending on the respective
