This application is based upon and claims the benefit of priority of the prior Japanese Patent Application No. JP2014-231905, filed on Nov. 14, 2014, the entire contents of which are incorporated herein by reference.
The present disclosure relates to a microorganism testing apparatus, method and program.
In recent years, on a site of work for counting the number of microorganisms or the like, media with easy handling and showing various kinds of forms, or various automated equipment have been widely applied. For example, Patent literature No. 1 discloses a sheet-form medium with easy handling. Moreover, Patent literature No. 2 discloses an apparatus for automatically fishing a bacterial colony. Moreover, Patent literature No. 3 and Non-patent literature No. 1 disclose a colony counter being an apparatus for automating counting of the number of microorganisms in food or the like, and for picking up culture media on which colonies grow by means of an image pickup apparatus to automatically count the number of microorganisms grown on the media by image analysis.
Bacteriological testing in food or the like is conducted according to procedures as described below, for example. More specifically, first, a medium is prepared, and then testing information such as a species name of a specimen to be provided for testing and a dilution factor is described on the prepared medium. Then, a material prepared by treating and diluting the specimen is inoculated into the medium, and cultured, and then the number of microorganisms grown on the medium is counted. Then, the counted number of microorganisms is recorded together with specimen information. The bacteriological testing is conducted according to such procedures, and therefore when many foods are tested, a large amount of labor and time is needed in an actual state. Thus, a desire is expressed for not only automation of counting of the number of microorganisms but also rationalization of a series of complicated work related to testing.
Consequently, the disclosure provides a microorganism testing apparatus, a microorganism testing method and a non-transitory computer-readable recording medium stored with a microorganism testing program according to which work related to testing of microorganisms can be rationalized.
In order to solve the problem described above, the present disclosure has been provided in which, if a content of microorganism testing on a specific specimen is selected or input, testing conditions of a relevant specific specimen are read from a storage device to print the conditions on a sheet-form medium, and if an image of the medium is read, the testing conditions and a type of the medium are acquired from the image to judge compatibility.
In detail, the disclosure is a microorganism testing apparatus equipped with a pre-processing unit in which, if the content of microorganism testing on the specific specimen is selected or input, the testing conditions of the specific specimen read from the storage device in which testing information specifying the testing conditions of the specimen is stored are printed on the sheet-form medium to be used for testing of the specific specimen, and a post-processing unit in which, if the image of the medium is read, the testing conditions printed on the medium and the type of the medium preliminarily labelled on the medium, are acquired from the image to output judgment results as to whether or not the testing conditions acquired from the image, and the type of the medium are compatible.
In a preparatory stage being pre-processing of the microorganism testing, the microorganism testing apparatus prints the testing conditions on the sheet-form medium to be used for testing of the specimen. The testing conditions to be printed on the medium are information read from the storage device in which the testing information specifying the testing conditions of the specimen is stored. Therefore, for example, when similar testing is repeated on a regular basis, the information can be reused, and preparatory work of the microorganism testing is saved. Then, if a person in charge of testing reads the testing conditions printed on the medium, the person can easily understand whether the medium is to be used for testing of any specimen. Therefore, for example, an error of wrong use of a different object is suppressed upon handling the specimen and the medium.
Further, in a data processing stage being post-processing of the microorganism testing, the microorganism testing apparatus analyzes the read image of the medium, and collates the testing conditions printed on the medium with labelling of the medium to output the results. Therefore, even if the wrong use of the medium occurs as described above, the apparatus can detect the wrong use to inform the person in charge thereof of the fact.
If the microorganism testing apparatus is applied, the work in the preparatory stage of the microorganism testing is saved as described above, and also the information to be printed on the medium by realization of work saving is effectively used for verification of testing in the data processing stage being the post-processing of the microorganism testing. Thus, the pre-processing and the post-processing are organically associated with each other to achieve overall rationalization of the work related to the testing of the microorganisms.
In addition, the pre-processing unit may print a symbol or a name representing the specific specimen, a dilution factor and a code produced by coding any other testing condition. If such a microorganism testing apparatus is applied, while information to be used for the post-processing in the microorganism testing is coded, the information to be understood upon handling the specimen of the medium is converted into a display form that can be recognized by the person in charge. Therefore, while the overall rationalization of the work related to the microorganism testing is achieved, the wrong use of the medium can be effectively prevented.
Moreover, an expiration date of the medium is preliminarily displayed on the medium, and the post-processing unit may further acquire, if the image of the medium is read, the expiration date displayed on the medium from the image to further output judgment results as to whether or not the expiration date acquired from the image has passed. If such a microorganism testing apparatus is applied, not only the wrong use of the medium but also erroneous processing of invalid tested result data can be suppressed.
Moreover, the post-processing unit may specify, if the image is read, the number of colonies grown on the medium, from the image. If such a microorganism testing apparatus is applied, an amount of work in the data processing stage being the post-processing of the microorganism testing can be reduced by using the image to be used for verification of the testing, and the overall rationalization of the work related to the microorganism testing can be achieved.
Moreover, in the testing conditions, a threshold value of quality determination of the number of colonies is further predetermined, and the post-processing unit may output the tested results of the specific specimen based on the specified number of colonies and the threshold value in the testing conditions. If such a microorganism testing apparatus is applied, judgment results of the tested results can be automatically obtained. Therefore, the overall rationalization of the work related to the microorganism testing can be achieved.
Moreover, the pre-processing unit may read, if the content of microorganism testing on the specific specimen is selected or input, the image of the medium to be printed, or may discriminate a shape or a size of the medium to be printed to further judge whether or not the testing conditions of the specific specimen read from the storage device, and the type of the medium to be printed are compatible. If such a microorganism testing apparatus is applied, culture of the microorganisms using an off-type medium can be prevented.
Moreover, the pre-processing unit may select, if the content of microorganism testing on the specific specimen is selected or input, from a plurality of kinds of media preliminarily arranged for the apparatus for applying printing onto the medium, the medium compatible with the testing conditions of the specific specimen read from the storage device to print the testing conditions on a selected medium. If such a microorganism testing apparatus is applied, work for exchanging the media is unnecessary in preparatory work for the microorganism testing, and when the plurality of kinds of media are handled in one-time preparatory work, the preparatory work is easy.
In addition, the disclosure can also be comprehended from an aspect of a method. For example, the disclosure may be a microorganism testing method which executes a pre-processing step, in which, if a content of microorganism testing on a specific specimen is selected or input, testing conditions of the specific specimen read from a storage device in which testing information specifying the testing conditions of the specimen is stored are printed on a sheet-form medium to be used for testing of the specific specimen, and executes a post-processing step, in which, if an image of the medium is read, the testing conditions printed on the medium and a type of the medium preliminarily labelled on the medium are acquired from the image to output judgment results as to whether or not the testing conditions acquired from the image, and the type of the medium are compatible.
Moreover, the disclosure can also be comprehended from an aspect of a non-transitory computer-readable recording medium stored with a computer program. For example, the disclosure may be a non-transitory computer-readable recording medium stored with a microorganism testing program that allows a computer to execute a pre-processing step, in which, if a content of microorganism testing on a specific specimen is selected or input, testing conditions of the specific specimen read from a storage device in which testing information specifying the testing conditions of the specimen is stored are printed on a sheet-form medium to be used for testing of the specific specimen, and to execute a post-processing step, in which, if an image of the medium is read, the testing conditions printed on the medium and a type of the medium preliminarily labelled on the medium are acquired from the image to output judgment results as to whether or not the testing conditions acquired from the image, and the type of the medium are compatible.
According to a microorganism testing apparatus, a microorganism testing method and a non-transitory computer-readable recording medium having stored with a microorganism testing program as described above, work related to microorganism testing can be rationalized.
An embodiment according to the disclosure will be described below. The embodiment shown below is provided for illustrative purposes only, and a technical scope of the disclosure is not limited thereto.
In addition, as computer 20, a desktop type, a laptop type, a tablet type and various kinds of other types can be applied. Moreover, in microorganism testing apparatus 10 related to the present embodiment, combination machine 30 having both the printer function and the scanner function is illustrated, but microorganism testing apparatus 10 related to the present embodiment may use a printer and a scanner as a different form, in place of combination machine 30. Moreover, the scanner function may be of a flat head type, a sheet feed type for incorporating a sheet-form material, or a type in which an image pickup device arranged apart from a subject picks up a whole image of the subject (for example, a stand type and a type utilizing a camera built in a smartphone).
If computer 20 in microorganism testing apparatus 10 executes the computer program stored in the storage device, the application for realizing a function block as described below starts.
Pre-processing unit 40 mainly takes charge of processing in which, if a content of microorganism testing on a specific specimen is selected or input, testing conditions of the specific specimen read from the storage device in which testing information specifying the testing conditions of the specimen is stored are printed on a sheet-form medium to be used for testing of the specific specimen. Moreover, post-processing unit 50 takes charge of processing in which, if an image of the medium is read, the testing conditions printed on the medium and a type of the medium preliminarily labelled on the medium are acquired from the image to output judgment results as to whether or not the testing conditions acquired from the image, and the type of the medium are compatible.
Hereafter, the processing content to be realized by computer 20 is described.
If the application is started, computer 20 displays, on the display device, a screen arranging menu buttons for selecting various kinds of operation and existing data.
The respective measured data arranged on data list 1e are preliminarily prepared by an administrator by using the administration screen to be called upon pushing setup administration button 1c, in which the data are preliminarily arranged in the form of a model in order to use the data of each item related to the testing content, such as a product name and an ingredient name of a testing object, a dilution factor, a template name showing a kind of a medium to be used, a date and time of testing and a title, for measurement work to be performed on a regular basis. For example, among the respective measured data arranged on data list 1e, third data from a top in which a status is “before measurement” show to the effect that lettuce used in a twice cooked pork lunch is to be tested, at 14:00, Sep. 4, 2014 in dilution by 100 times by using a medium for aerobic plate count.
Here, if a person in charge of testing operates computer 20, and for example, among the respective measured data arranged in data list 1e, selects data of a desired test content, checks check box 1f and clicks output button 1g (S101), computer 20 executes processing as described below.
In addition, when no data related to the desired testing content are found in data list 1e, the person in charge of testing pushes setup administration button 1c on measured data list screen 1 to open the administration screen, and can input the data of the desired testing content to add such data to data list 1e.
In addition, on medium 60, in addition to the information printed by combination machine 30, lot number 64, expiration date 65 of medium 60, and labelling 67 representing the type of the medium are originally printed.
More specifically, if measured data registration button 1b is clicked, computer 20 actuates combination machine 30 to read an image of medium 60. Then, computer 20 reads two-dimensional barcode 63 and expiration date 65 visible on the read image of medium 60. From data list 1e, computer 20 searches out data in agreement with the measured data obtained by decoding read two-dimensional barcode 63. Moreover, based on read expiration date 65, computer 20 judges whether or not medium 60 used in the testing has expired through the expiration date. Then, computer 20 displays a confirmation screen of measured data to be registered (S104).
If measurement result registration button 4e on registration screen 4 shown in
If microorganism testing apparatus 10 related to the embodiment is applied, the testing conditions are printed on the sheet-form medium to be used for testing of the specimen in the preparatory stage being pre-processing of the microorganism testing. Accordingly, if the person in charge of testing reads the testing conditions printed on the medium, the person can easily understand whether the medium is to be used for testing of any specimen. For example, such an error as the wrong use of different object upon handling the specimen and the medium can be suppressed. Further, microorganism testing apparatus 10 related to the embodiment analyzes the read image of the medium, in a data processing stage being post-processing of the microorganism testing, and collates the testing conditions printed on the medium with labelling 67 on the medium to output the results. Therefore, even if the wrong use of the medium occurs, microorganism testing apparatus 10 can detect the wrong use and inform the person in charge thereof of the fact. Moreover, if microorganism testing apparatus 10 related to the embodiment is applied, work in the preparatory stage of the microorganism testing is saved, and also information to be printed on the medium by realization of work saving is effectively used for verification of testing in the data processing stage being the post-processing of the microorganism testing. Thus, the pre-processing and the post-processing are organically associated with each other to achieve overall rationalization of the work related to testing of the microorganisms.
In addition, microorganism testing apparatus 10 related to the embodiment can also be modified as described below, for example. More specifically, microorganism testing apparatus 10 related to the embodiment may automatically judge whether or not the type of medium 60 set in combination machine 30 is compatible with the testing content to be printed, in the pre-processing in which printing is applied onto medium 60, and in case of negative judgment, suspend printing to display the judgment results on the screen, for example. The type of medium 60 set in combination machine 30 may be identified by reading labelling 67 preliminarily provided for medium 60 by the scanner function of combination machine 30 or any other scanner, or by alternating a shape or a size of medium 60 for every type, and using information on the shape or the size of medium 60 acquired from an image read by a sheet size discrimination function or the scanner in combination machine 30, for example. If microorganism testing apparatus 10 related to the embodiment is thus modified, culture of microorganisms using off-type medium 60 can be prevented.
Moreover, for example, when a plurality of sheet trays in which media before printing are set are equipped in combination machine 30 or the printer, microorganism testing apparatus 10 related to the embodiment may automatically select a sheet tray in which medium 60 to be compatible with the testing content to be printed is set to print the testing content on medium 60 set in the selected sheet tray. If microorganism testing apparatus 10 related to the embodiment is thus modified, work for exchanging media 60 is unnecessary in the preparatory work of the microorganism testing, and when a plurality of kinds of media 60 are handled in one-time preparatory work, the preparatory work is easy.
