Abstract

A method for operating a cleaning device or a cleaning system is proposed. In this case, the cleaning device is set up for carrying out a process for cleaning an article with a germicidal action. The method includes the following steps: information on a target germ with which the article could be contaminated is received; at least one process parameter of the cleaning process is selected according to the target germ in such a way that the target germ is killed with a high degree of probability during the cleaning process; and the cleaning process is carried out with the process parameter.

Claims (28)

1. A method for operating a cleaning device or a cleaning system, the cleaning device being set up for carrying out a process of cleaning an article with a germicidal action, the method comprising:

receiving information on a target germ with which the article could be contaminated;

selecting at least one process parameter of the cleaning process according to the identified target germ such that the target germ is killed with a high degree of probability during the cleaning process; and

performing the cleaning process based, at least in part, on the selected process parameter,

wherein a temperature with which the article is acted upon and a time of action in which the article is acted upon with the temperature is measured during the cleaning process, and

wherein the information on the target germ is assigned an experimental value of a target thermal equivalent, corresponding to the target germ, at which the target germ is killed with a high degree of probability, wherein said selecting selects the at least one process parameter such that the cleaning process is carried out such that the article is acted upon at least with the target thermal equivalent.

2. The method according to claim 1 , the at least one process parameter comprising at least one of the following parameters: a temperature; a time of action of a cleaning step with a cleaning liquid; a temperature of a cleaning liquid; a temperature of a thermal treatment step; a time of action of a thermal treatment step; a selection of a disinfectant; a type of a disinfectant; a quantity of a disinfectant; a time of action of a disinfectant; a steam temperature of a steam disinfection step; or a time of action of a steam disinfection step.

3. The method according to claim 1 , wherein the target thermal equivalent corresponds to a thermal equivalent according to the EN ISO 15883 standard or to the NSF3 standard.

4. The method according to claim 1 , wherein the target thermal equivalent comprises an Ao value and/or an H.U.E. value.

5. The method according to claim 1 , wherein at least one of the temperature that is measured and/or the time of action that is measured is regulated or controlled.

6. The method according to claim 1 , wherein an assignment of one or more target germs to one or more process parameters is used, and wherein the assignment comprises at least one of the following elements: a database; a list; a table; a matrix; or a correlation curve.

7. The method according to claim 1 , wherein a plurality of target germs are combined into target germ groups or target germ classes with common parameters.

8. The method according to claim 1 , wherein the target germ is selected according to a regional, national or worldwide frequency or frequency distribution of infections and/or epidemic warning and/or a medical diagnosis.

9. The method according to claim 1 , wherein the cleaning process is carried, out, independently of the target pathogen, at least with a minimum parameter set for achieving a minimum germicidal action.

10. A cleaning system for cleaning an article, the cleaning system comprising:

a cleaning device that is set up for carrying out a process of cleaning the article with a germicidal action,

wherein the cleaning system is set up for receiving information identifying a target germ with which the article could be contaminated,

wherein the cleaning system is set up for selecting at least one variable process parameter of the cleaning process according to the target germ such that the target germ is killed with a high degree of probability during the cleaning process, and

wherein the cleaning system is set up for controlling the cleaning device to carry out the cleaning process based, at least in part, on the selected process parameter, and

wherein the central control is set up for assigning a target thermal equivalent to the target germ or to the target germ class and for transferring information on the target thermal equivalent to the cleaning devices, the cleaning device being set up for carrying out in each case a cleaning process in such a way that the articles to be cleaned are acted upon with the target thermal equivalent.

11. The cleaning system according to claim 10 , wherein the cleaning system further comprises an input device that enables a user to enter the information identifying a target germ or a target germ class, in particular to select a target germ or a target germ class from a target germ list or target germ class list.

12. The cleaning system according to claim 11 , wherein the input device includes, means for displaying to the user at least one of a list of target germs or a list of target germ classes, and means for the user to select a target germ or a target germ class from the displayed target germ list or the displayed target germ dais list.

13. The cleaning system according to claim 10 , wherein the cleaning system further comprises an interface in order to receive information on a regional, national or worldwide frequency or frequency distribution of infections, and/or an epidemic warning and/or information from a medical patient database.

14. The cleaning system according to claim 10 , w wherein the cleaning system further comprises at least one of the following cleaning devices: a dishwasher, in particular an industrial dishwasher, in particular a single-chamber dishwasher or a continuous-flow dishwasher; a cleaning device for cleaning medical implements or nursing utensils with a high incidence of liquids, in particular a basin washer; or a cleaning device for the disinfection of medical instruments without or with a low incidence of liquids, in particular a thermal disinfection device, in particular an autoclave, and/or a steam disinfection device.

15. The cleaning system according to claim 14 wherein the cleaning device for cleaning medical implements or nursing utensils with a high incidence of liquids includes a basin washer for carrying out a basin washer cleaning process according to the selected process parameter.

16. The cleaning system according to claim 14 wherein the cleaning device for the disinfection of medical instruments without liquids or with a low incidence of liquids comprises a thermal disinfection device for carrying out a thermal disinfection process according to the selected process parameter.

17. The cleaning system of claim 16 , wherein the thermal disinfection device includes at least one of an autoclave for carrying out an autoclaving cleaning according to the selected process parameter or a steam disinfection device for carrying out a steam disinfecting process according to the selected process parameter.

18. The cleaning system according to claim 10 , wherein the cleaning system further comprises a plurality of cleaning devices and a central control, the central control being set up for receiving the information on the target germ centrally for the cleaning devices.
