The sterilizer of the present invention is configured to be able to store operation data as a sterilization record. By using this operation data, sterilization management can be performed with a sterilizer and / or an external device, which contributes to the establishment of traceability.

  The sterilizer includes a treatment tank in which an object to be sterilized is accommodated and sterilized, and an operation panel operated by a user. The article to be sterilized is not particularly limited, but is typically a medical instrument such as a surgical knife. The treatment tank is a hollow container that can be sealed, and a material to be sterilized is taken in and out through a door. Two doors may be provided in the treatment tank, and a carry-in door for putting a material to be sterilized in the treatment tank and a carry-out door for taking out the material to be sterilized after sterilization may be provided separately.

  The processing tank is provided with various configurations for sterilizing an object to be sterilized accommodated in the processing tank. The method of sterilization is not particularly limited, but for example, steam is used. In this case, the sterilizer is configured as a steam sterilizer.

  The operation panel is a device that performs various input / output operations with the user. The operation panel is preferably attached to the sterilizer itself. Typically, it is provided on the wall surface of the processing tank beside the door of the processing tank. The operation panel of this embodiment includes a touch screen and various operation buttons. The touch screen is configured by arranging a touch panel on the surface of a display. A liquid crystal display is typically used as the display. The touch screen performs various displays on the display, and when the display button is pressed, the touch panel detects it and enables various settings or operations while appropriately changing the screen display.

  The sterilizer is set with sterilization conditions and the like by the operation panel, and the operation is executed with the set contents. When the operation is completed, the operation panel is urged to input the result of the sterilization indicator. In the present embodiment, a screen prompting input of the result of the sterilization indicator is output on the touch screen. On the other hand, the user inputs the result information of the sterilization indicator by operating the operation panel. For example, the result information of the sterilization indicator is input by operating a button displayed on the touch screen. The input result information is stored in the operation data storage means for each operation as part of the operation data.

  The sterilizer of this embodiment is configured to be able to select and execute a sterilization operation or Bowie-Dick test as an operation mode. Chemical indicators and / or biological indicators are used for sterilization operation, but Bowie-Dick test indicators are used for Bowie-Dick tests for finding defects in the sterilizer itself. Therefore, when the operation is completed, it is preferable to perform an output that prompts the result input of the type of sterilization indicator corresponding to the operation mode.

  In the case of chemical indicators and Bowie-Dick test indicators, it is confirmed whether or not the desired sterilization has been performed in the treatment tank by changing the color, etc., and in the case of biological indicators, by culturing. The result is input as result information.

  By the way, the operation mode can be selected by a touch screen of the operation panel. In addition, it is preferable that the input of the result information through the operation panel is impossible to be corrected more than the set number of times. For example, the correction can be performed only once, and the second and subsequent corrections cannot be performed. In other methods, it is preferable to improve the sterilization management reliability that the operation data stored in the operation data storage means cannot be corrected.

  The operation data storage unit stores operation data for each operation. The operation data includes at least the result information of the sterilization indicator described above. Further, the operation data can include desired information such as the operation mode, the operation date and time, and the temperature, pressure, and time in the treatment tank during the sterilization process.

  The operation data stored in the operation data storage means can be viewed on the operation panel. Specifically, by operating the touch screen, desired operation data is acquired from the operation data storage means and displayed on the display.

  The operation data stored in the operation data storage means can be configured to be downloadable to an external device. In this case, the sterilizer and the external device may be connected in a wired or wireless manner so as to be capable of bidirectional communication. Or it is good also as a structure which writes operation data in the portable storage medium (storage medium) attached or connected to the sterilizer, and reads the information with an external device. In this way, operation data can be viewed and managed in an external device.

  In order to establish traceability, it is preferable to manage identification information unique to each item to be sterilized in association with operation data. For example, an IC tag, a bar code, a stamp, etc. are given to the article to be sterilized, and the identification information based thereon is stored for each sterilization operation. However, when a plurality of articles are packed, for example, and carried into the processing tank, the identification information may be attached to each pack. That is, in this case, the article to be sterilized is considered in units of one pack.

  When it is desired to confirm the sterilization record of a certain object to be sterilized, operation data when the object to be sterilized is sterilized is output based on the identification information of the object to be sterilized. Thereby, for example, when and in which sterilizer each sterilization object is sterilized can be confirmed. Moreover, if the result information of the sterilization indicator is included in the operation data, the sterilization result can be confirmed. Furthermore, if information such as the temperature and pressure in the treatment tank during the sterilization process is included in the operation data, it is possible to confirm under which environment the sterilization is performed.

  Such management may be performed by the sterilizer itself or by an external device. When using the sterilizer itself, it can be done on the operation panel. When managed by an external device, information unique to each sterilizer is also used so that it can be confirmed which sterilizer is sterilized in which sterilizer and under what environment. In order to read the identification information, the sterilizer and / or the external device preferably includes an IC tag reader and / or a barcode reader.

  Moreover, when managing by an external device, the input of identification information may be performed by a sterilizer or an external device. When the identification information is input with the sterilizer, the operation data storage unit stores the identification information of one or a plurality of articles to be sterilized for each sterilization operation in association with the operation data. The information can be downloaded to an external device.

  Incidentally, the operation panel 24 is provided with a LAN cable connector (not shown). Therefore, the operation panel 24 and the external device 70 can be connected via the LAN cable 69. The external device 70 is, for example, a device that constitutes an in-hospital management system, and typically includes a personal computer (personal computer).

  By connecting the operation panel 24 and the external device 70 via the LAN cable 69, the operation data stored in the operation data storage unit 29 can be taken into the external device 70. As a result, operation data can be managed and viewed in the external device 70. In this embodiment, since the operation data is stored in the CSV format in the operation data storage unit 29, it can be easily used in spreadsheet software or the like. The external device 70 can be connected to a plurality of sterilizers 1 (operation panel 24). In this case, the operation data includes information for identifying which sterilizer 1 is the operation data. .

  The acquisition of the operation data by the external device 70 can be configured to be automatically performed every time the operation of the sterilizer 1 is completed. It is also possible to provide communication functions such as operation monitoring, accumulated data, alarm history, and status monitoring when an alarm occurs.

  The operation panel 24 of this embodiment is further provided with a USB (Universal Serial Bus) connector (not shown). Therefore, various USB compatible devices (not shown) can be connected to the operation panel 24. For example, a portable storage medium (storage medium) such as a USB memory can be connected, and operation data can be copied to the USB memory or the like by operating the operation panel 24. Then, if the data is taken into an external device 70 such as a personal computer, the same use as when connected by the LAN cable 69 becomes possible.

  In this way, the operation data in the operation data storage unit 29 can be read out by the external device 70, but it is impossible for the user and maintenance personnel to correct or delete the operation data in the operation data storage unit 29 itself. The configuration is preferable in order to increase the reliability of data.

  By the way, in order to establish traceability, it is preferable to manage identification information unique to an object to be sterilized in association with operation data. For example, an IC tag, a bar code, a stamp, etc. are given to each article to be sterilized, and identification information based on it is stored for each sterilization operation. In order to read the identification information, the sterilizer 1 and / or the external device 70 are provided with an IC tag reader and / or a barcode reader.

  When it is desired to confirm the sterilization record of a certain object to be sterilized, operation data when the object to be sterilized is sterilized is output based on the identification information of the object to be sterilized. Thereby, for example, it can be confirmed in which sterilizer 1 each article to be sterilized is sterilized. Moreover, if the result information of the sterilization indicator is included in the operation data, the sterilization result can be confirmed. Furthermore, if information such as temperature and pressure in the treatment tank 2 during the sterilization process is included in the operation data, it is possible to confirm under which environment the sterilization is performed.

  Such management may be performed by the sterilizer 1 itself or by the external device 70. When performing with the sterilizer 1 itself, it can be performed with the operation panel 24. When managing by the external device 70, the identification information may be input by the sterilizer 1 or the external device 70. When the identification information is input by the sterilizer 1, the operation data storage unit 29 stores the identification information of one or a plurality of articles to be sterilized for each sterilization operation in association with the operation data.

  The sterilizer 1 equipped with the sterilization management function of the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate. In particular, the structure and operation method for sterilizing an object to be sterilized are not limited to the above-described embodiments. For example, in the said Example, although the two doors were provided in the processing tank 2, it is good also as only one door of the processing tank 2. FIG. In the above embodiment, the decompression means of the exhaust pipe 7 is the vacuum pump 13, but a steam ejector, a steam condensation heat exchanger, or the like may be provided instead of or in addition to this.

  Moreover, each item of a setting value and driving | running | working data is only an example, and is changed, added or deleted suitably. Furthermore, the screen examples shown in FIGS. 2 to 10 are examples and can be changed as appropriate. In addition, the numerical values, characters, buttons, and the like shown in the drawing are merely examples, and it goes without saying that the present invention is not limited thereto.

  Moreover, in the said Example, after issuing the inquiry screen 38 (FIG. 2, FIG. 3) which prompts the result input of a sterilization indicator at the time of completion of operation, via the operation record data screen 41 (FIG. 7, FIG. 8), “ The sterilization indicator result input screen 48 (FIG. 4) is displayed by pressing the “CI result input” button 45 or the like, but the “Yes” button 39 is pressed on the inquiry screen 38 (FIGS. 2 and 3). Thus, the result input screen 48 (FIG. 4) may be displayed immediately. Alternatively, the result input screen 48 (FIG. 4) may be displayed immediately upon completion of operation.

  By the way, the establishment of traceability by managing the identification information of the article to be sterilized in association with the operation data can be widely applied not only to the sterilizer 1 of the above embodiment but also to a general sterilizer. .
