Definitions
- the invention relates to a method for analyzing ingredients of the exhaled air using electrochemical sensors and / or biosensors. The determination is made by measuring and evaluating signals which generate one or more of the sensors upon contact with these substances or with reaction products formed from these substances. These substances to be examined are also condensed on the condensation of the water contained in the respiratory gas at a condensation surface. The resulting breath condensate is fed directly to the sensors. The condensation surface is functionalized or activated, so that an interaction or a chemical reaction takes place during the condensation process with the condensate and / or the substances to be analyzed, whereby the signal generated at the sensors is influenced.
- the invention also relates to a device for obtaining respiratory condensates.
- a base element (a holder or a support) at least one sensor unit, which in addition to the sensors has a correspondingly functionalized or activated condensation surface. Furthermore, it comprises at least one Peltier element and a réelleleit Kunststoff.
- the base element can be connected to a head support and positioned directly in the breath stream directly in front of the mouth of the wearer and optionally connected to a portable power supply and electronic evaluation system.
- DE 199 51 204 C2 describes a method for analyzing the constituents of the exhaled air, in which the exhaled air is cooled until its aerosol and vapor components are condensed until a predetermined amount of sample is reached.
- the predetermined amount of sample is determined by a complete filling or saturation of a storage layer or a filter.
- the determination of the substances contained in the condensate takes place at one or more electrochemical sensors, which are arranged downstream of the storage layer or the filter, wherein the breath condensate diffuses through the filter or the storage layer on the sensors.
- the application of the solutions from the reservoirs to the sensors for the purpose of measuring, sensor conditioning or calibration of the sensors is carried out by means of a special apparatus which acts on the reservoir and is not part of the cassette.
- the sample solution, the breath condensate is aspirated or injected from a sample vessel or sample collection system prior to measurement, and mixed with in-cassette or out-of-cassette materials or solutions for dilution and / or ionic concentration prior to application to the sensors. and / or conductivity change. After the measurement, the cassette is discarded.
- a disadvantage is the great equipment expense for obtaining a sufficient amount of sample, which is carried out with a separate apparatus, after which the sample may still have to be subjected to a dilution.
- biosensor consisting of an electrode-printed thick film substrate having thereon a moisture absorbing layer containing an enzyme which reacts with the substance to be determined contained in the gas phase.
- the use of this biosensor for analysis has the disadvantage that the introduction of the sensor into the gas phase to be examined determines the starting point of the sample collection by absorption and their speed on the one hand from the initial state of the sensor and on the other by the environment (eg humidity and flow conditions of the sensor surface) in the gas depends.
- the polymers may contain inorganic alkali metal salts, such as the chlorides KCl or NaCl, which dissolve in the breath condensate and thus lead to a change (increase) in the conductivity and allow measurements with electrochemical sensors.
- inorganic alkali metal salts such as the chlorides KCl or NaCl
- Particular preference is given to using polymer layers of polyurethane or polyurethane mixtures, cellulose derivatives and / or polymeric silicon compounds.
- the preparation of appropriately functionalized or activated organic polymers may be accomplished by adding salts or other additives to polymer suspensions or mixtures of polymer suspensions prior to crosslinking of the polymers.
- the salts or other additives are incorporated in the polymer layer.
- Another possibility of polymer functionalization is to add chemical reactants such as e.g. To immobilize enzymes for substances to be detected in the polymers or on their surface.
- the wetting properties of these polymers can be influenced, which has an effect on the droplet size, the confluence of the condensate droplets and thus on the entire course of the sample collection.
- the surface of the condensation surfaces is such that the forming condensate droplets flow together to larger and smaller droplets. Within this relatively short period of time, they surprisingly absorb the substances (substances) which are contained, for example, in the polymer. Thus, as already stated, for. B. influence the conductivity of the condensate. Furthermore, the substances to be determined z. B. react with immobilized in the polymer layer enzymes to easily detectable reaction products. For example, lactate contained in breath condensate can be catalysed by lactate oxidase to react to pyruvate and hydrogen peroxide, which is easily detectable electrochemically.
- the device according to the invention for obtaining respiratory condensates and for the immediate determination of substances present in the respiratory air comprises on a base element in the form of a carrier or a holder with corresponding contacts at least one sensor unit, at least one Peltier element for cooling and between Peltier Element and condensation surface at least one réelleleitmaschine.
- the sensor unit has at least one functionalized or activated condensation surface.
- the sensor unit comprises at least one sensor, wherein condensation surface (s) and sensor (s) are connected so that the condensate can pass directly and directly to the sensor.
- Electrochemical sensors and / or biosensors are used, which can be connected to power supply and electronic measurement, control and evaluation systems.
- the device has the great advantage that in addition to normal standard devices in the hospital and laboratory area and portable systems that are also suitable for point-of-care use, can be used.
- the Peltier element in combination with temperature sensors, which measure the ambient temperature and the temperature of the cooled surface, the temperature of the cooled surface and thus the timing and duration of the condensate collection is easy to control.
- condensation surface it is possible to control cascades or alternating condensation processes by dividing the condensation surface into a plurality of condensation surfaces and their corresponding thermal insulation in combination with one or more Peltier elements.
- a planar fluidics can be established and interaction effects or chemical processes can be targeted be initiated. The latter happens, for example, in that the condensate absorbs the substances that have been deliberately introduced.
- a ceramic substrate which is provided with a 2-electrode structure in thick film technology
- a condensation surface which is covered with a functionalized with the enzyme lactate oxidase Hydroxyethylcelluose layer.
- Condensation surface and 2-electrode structure on the ceramic together form the sensor unit.
- This is used in a holder, which is equipped with Peltier element, bathleit Hampshire and electrical spring contacts and connected to a measuring and control unit.
- a voltage of +450 mV is applied between the two electrodes of the 2-electrode structure, in which the hydrogen peroxide formed as a by-product of the lactate oxidase-catalyzed reaction with the lactate present in the respiratory condensate is electrochemically oxidized.
- the condensation surface is first cooled from room temperature to 14 0 C. Thereafter, the subject directs his breath on the condensation surface of the sensor unit until a certain amount of condensate has accumulated and reaches the electrode structure.
- the wetting of the sensor structure with the respiratory condensate manifests itself in a rapid increase and decay of the sensor flow dependent on the lactate concentration. 30 seconds after wetting of the electrode structure, a current of 12 nA was measured for a lactate content of 50 ⁇ mol / l in the respiratory condensate, while in a lactate-free comparative sample a current of 5 nA was also measured 30 s after wetting (see FIG. 5).
- Slits (2.4) is provided for heat and mass transfer to the environment, with a sensor unit (2.3), Peltier element and
