Definitions
- the present invention relates to a method for measuring the killing effectiveness of a disinfectant against microorganisms and their spores (Überdauerunsformen) with a sensor system having at least two sensors, wherein the at least two sensors in contact with the
- hydrogen peroxide H 2 O 2
- H 2 O 2 hydrogen peroxide
- Disinfectant to remove This known method is extremely effective and has long been known. Methods for measuring the concentration of a degermination medium have long been known in various designs.
- test microorganisms of known resistance to a treatment with a disinfectant to then be able to conclude by the reduction of these microorganisms on the sterilizing power of the tested method can (DE 602 06 254 T2).
- the invention is therefore based on the object, the method described above and previously described in more detail and a corresponding device for measuring the killing
- the above object is achieved in a method according to the preamble of claim 1, characterized in that during the signal acquisition a validated, if necessary. Biological, germ reduction test for determining the germ reduction rate is performed and that the measured signals are set in a certain ratio to each other and to each Condition of the disinfecting agent is calculated a specific pattern, which serves as the basis for a reproducible ratio of signal data and sterilization effect.
- the inventive method thus uses a plurality of sensors, which from the relevant parameters such
- reducing gases or gas components etc. calculate a sum signal.
- the parameters relate to direct (temperature, pressure, concentration, etc.) and indirect (oxidizing and reducing components, for example due to decay of H 2 0 2 ) sizes.
- the totality of the measuring signals of the sensors used which have a sensitivity to the relevant parameters, serves to detect different "states" of the disinfecting agent, whereby a specific "pattern" of the signals of the sensors is obtained for each state of the disinfecting agent.
- the performance of a validated germ reduction test for determining the sterilization effect takes place simultaneously with the detection of the sensor signals.
- the result of the germ reduction test such as the germ reduction rate, then becomes that of the sensory
- the inventive method therefore differs from the previous approaches to determine the
- Influencing variables such as humidity, temperature, etc. are determined on the basis of parametric parameters, but based on the correlation described, the respective sterilization effect is determined directly.
- the method according to the invention is therefore able to take into account all variables influencing the sterilization. In that sense, that uses
- the germicidal effect does not result solely from the concentration of the disinfecting agent, the temperature or other parameters.
- the germicidal effect of a disinfectant may be due to the oxidative properties of chemical compounds
- a sensor system is used which is in direct contact with the vaporous or gaseous material used
- Disinfectant stands. Alternatively, it is also possible that in a liquid disinfectant the
- Sensor system is in indirect contact with the disinfectant, ie above the level is arranged.
- Multi-sensor arrangement often also referred to as "artificial nose.” Such multi-sensor arrangements have a plurality of sensors and have been known for some time (DE 102 36 327 AI).
- Disinfectant determine the sterilization effect based on the sensor signals.
- a signal is continuously generated by coupling the sensory signals during a degermination process, which is proportional to the effectiveness of the degermination process.
- This generated signal can be processed either inline or online.
- the invention provides that hydrogen peroxide, peracetic acid, ethanol or other known substances can be used as sterilizing agents.
- the used sensor system can therefore be calibrated and applied with any disinfecting agents.
- the object is achieved in that the sensor system has a plurality of sensors, which are combined to form a multi-sensor unit which is connected to a computing unit.
- the sensors of the sensor system can be used in vapor-like or gaseous media at temperatures up to 900 ° C.
- Catalyst are connected, for example with pellistors. It is clear that the accuracy of the method according to the invention increases with the number of sensors used. According to a further preferred embodiment of the invention, the arithmetic unit to a data recorder for
- Data transmission which is connected via a transmitter with a computing unit.
- a computing unit Preferably ensures a
- Memory for storing output quantities and / or calibration data.
- a control unit is used to control the operating parameters of the sensors used in the sensor system.
- Power supply of the individual blocks is a suitable power supply provided.
- Fig. 1 shows a device according to the invention, schematically as
- Fig. 2a, 2b and 2c different positioning possibilities of the sensor system
- Fig. 3 is a comparison of the measured values of two
- FIG. 1 shows a multi-sensor arrangement in which a plurality of individual sensors Mi, M 2 , M n is arranged.
- the multi-sensor arrangement 1 may optionally consist of a noble metal, heat-resistant and / or acid-resistant plastic or another suitable material.
- the individual sensors Mi to M n of the multisensor arrangement 1 are connected via unspecified cable lines to a data recorder 2. This allows the
- Data recorder 2 are mounted at any location.
- the data recorder 2 is used for data transmission between the n sensors i to M n of the multisenor unit 1, a
- the n sensors Mi to M n are regulated. These include, for example, the
- the transmitter 3 serves to convert the analog sensor signals into digital data. These are processed by the arithmetic unit 4.
- a memory 5 in which the data of the output variables or the calibration data are stored.
- the calculation of the respective output variable takes place simultaneously in the arithmetic unit 4.
- the output variable can optionally be output via a display integrated in the arithmetic unit 8, an external screen or a printer (all three not shown) and / or stored in the memory 5.
- a power supply unit 7 sets the supply voltage for the
- Components 2 to 6 safely.
- the components 2 to 7 may be housed in whole or in part in a housing. It is also conceivable that all or parts of components 2 to 7 are replaced or supplemented by a PC.
- the described measuring device can be integrated, for example, as a fixed component in a sterilizer.
- Fig. 2 shows possible arrangements of the multi-sensor arrangement 1 in a sterilizer.
- the multi-sensor arrangement 1 can optionally directly in the vicinity of the outlet of a sterilizer.
- Feeding means 9 for a vaporous or gaseous sterilizing agent Si (see Fig. 2a), at an arbitrary Place in a sterilization chamber 10, in which the steam-like or gaseous sterilizing agent S 2 is distributed in space (see Fig. 2b) or in the case of a liquid
- Multi-sensor arrangement 1 is (see Fig. 2c).
- Measuring device also as a compact system in the sense of a
- portable handset can be executed, thereby
- the transmission of data between the individual components can also be wireless.
- FIG. 3 shows a comparison of the measured values of two sensors, sensor 1 and sensor 2, as an arbitrary one
- FIG. 3 seven unspecified measuring points are shown, which for different "states" of a
- Disinfectant were recorded. The collection and comparison of these data for different "states" of the disinfectant corresponds to the calibration of the
