Description
Technical Field
The present invention relates to a cleaning management method and apparatus for managing a cleaning state of an endoscope, and an endoscope management system.
Background
In the medical field, electronic endoscopes are widely used for examination. The electronic endoscope includes an insertion portion to be inserted into a body cavity of a patient, and an operation portion for operating the insertion portion. The distal end of the insertion portion is provided with an illumination portion for illuminating an observation site in the body cavity, a solid-state imaging element such as a CCD for imaging the observation site, and the like. The image pickup signal output from the CCD is transmitted to a processor device electrically connected to the electronic endoscope. Various signal processes are performed by the processor device and displayed as an observation image on a monitor.
An electronic endoscope used for medical examination is cleaned by a dedicated cleaning machine and then placed in a storage room for storage until the next medical examination. In the cleaning process, the used electronic endoscope is loaded into a cleaning tank of the cleaning machine to automatically perform the steps of cleaning, disinfecting, rinsing, drying and the like. However, even if the cleaning process is performed by this cleaning machine, body fluid, dirt, and the like may remain in the electronic endoscope without being removed. Therefore, a simple cleaning process (hereinafter, referred to as "pre-cleaning") is performed before a cleaning process (hereinafter, referred to as "main cleaning") is performed by a cleaning machine (see, for example, japanese patent laid-open nos. 2009-268508 and 2007-325724).
The precleaning is performed by a manual operation of a cleaning worker, and the external surface of the electronic endoscope is wiped with gauze or cloth, or body fluid and dirt entering the forceps channel (suction channel) and the air/water supply nozzle are removed with a brush. Which cleaning method is to be used is appropriately determined in consideration of the degree and nature of contamination of the electronic endoscope.
In addition, since the used electronic endoscope is cleaned and reused, there is a concern that infection may be expanded through the electronic endoscope in the case of infectious diseases. Therefore, in order to ensure traceability and to trace the infection source, it is stipulated that history management is required. Under such circumstances, it is necessary to create a history for each electronic endoscope at each stage of inspection, cleaning, storage, and the like.
In the production of history of the cleaning stage of the endoscope, it is preferable to perform pre-cleaning and main cleaning separately. The cleaning machine for main cleaning has the function of inputting endoscope identification information, name of cleaning operator, cleaning date, cleaning content and other cleaning history; a function of recording the cleaning history; and a function of outputting to a Local Area Network (LAN) or the like. On the other hand, since the pre-washing is performed by manual work, it is difficult to record the history of the pre-washing with electronic data at the stage of the pre-washing. Therefore, the history management of the pre-washing is not sufficient at present.

Fig. 10 shows a cleaning history unit 67S in which cleaning history information of the 1 st to n-th cleaning processes is stored.
The DB controller 102 is used to perform a query of supplementing, updating, and searching for predetermined information and output a search result to the examination image DB 66 and the endoscope cleaning history DB68 based on a predetermined request signal.
Main-cleaning-machine control unit 103 includes determination unit 103A, warning control unit 103B, and main-cleaning control unit 103C. The determination unit 103A searches the endoscope cleaning history DB68 for the endoscope cleaning history 67 (see fig. 10) that matches the endoscope identification information of the main cleaning identification information Y21 received by the endoscope management server 25. The determination unit 103A determines whether or not the pre-cleaning history Y1 not paired with the main cleaning history Y2, that is, the individual pre-cleaning history Y1 is included in the searched endoscope cleaning history 67. The warning control unit 103B transmits a warning request signal to the main washer 23. The main-cleaning control unit 103C transmits a main-cleaning start permission signal or a main-cleaning start prohibition signal to the main cleaner 23.
The CPU of the operation terminal 26 functions as a cleaning history output request unit 110 and a communication unit 111 by executing a client program. The cleaning history output request unit 110 outputs a cleaning history request signal concerning predetermined endoscope identification information to the endoscope management server 25. The communication unit 111 is composed of a terminal transmission unit and a terminal reception unit. The terminal transmitting section transmits a predetermined request signal to the network 13. The terminal receiving unit receives a predetermined signal to the operation terminal 26.
In this way, the endoscope management system 10 functions as a cleaning management apparatus that manages the endoscope cleaning history 67 and an image management apparatus that manages the examination image. The cleaning management device is composed of a pre-cleaner 22, a main cleaner 23, an operation terminal 26, a printer 27 (see fig. 1), an endoscope cleaning history DB68, and respective members 100 to 103. The image management apparatus is composed of the operation terminal 26, the endoscope controller 21 (see fig. 1), the DB controller 102, and the inspection image DB 66 (see fig. 1).
Next, the operation of the above embodiment will be explained. As shown in fig. 1, in the endoscopy room 11a, endoscopy is performed using an electronic endoscope 12. In the endoscopic examination, the insertion portion 30T of the electronic endoscope 12 is inserted into the body cavity. The observation site is irradiated with illumination light from the distal end portion of the insertion portion 30T. The observation site in the illumination is imaged by a CCD disposed at the distal end portion. The image pickup signal from the CCD is subjected to various image processing by a processor device in the endoscope controller 21. The obtained image of the observation site is displayed on a monitor in the endoscopic room 11 a. When still image photographing is performed, the still image is stored as observation information 65 in the examination image DB 65 together with endoscope identification information, examination subject, examination date, examination doctor name, and the like. The information 65 stored in the inspection image DB 65 can be viewed by the operation terminal 26.
When the endoscopic examination is completed, the used electronic endoscope 12 is subjected to pre-cleaning in the pre-cleaning chamber 11b and main cleaning in the main cleaning chamber 11c, and then placed in the storage chamber 11d for storage until use at the time of the next examination. The pre-cleaning is performed by manual work until the cleaning level of the electronic endoscope 12 reaches a certain level. The main washing is automatically performed according to a predetermined washing menu.
In the preliminary cleaning shown in fig. 11, the used electronic endoscope 12 is cleaned in the water tank 41 (see fig. 3) (S10). At this time, while water and a cleaning agent are supplied into the water tank 41, body fluid, blood, and the like that have firmly adhered to the surface of the electronic endoscope 12 are removed with a brush 44 (see fig. 3).
The pre-wash controller 47 reads endoscope identification information from the IC tag 30TG (see fig. 2) of the used electronic endoscope 12 via the tag reader 45 (see fig. 7) (S11). This endoscope identification information is used as the pre-washing identification information Y11. The pre-wash controller 47 causes the display on the operation panel 46 to display pre-wash execution information Y12 (see fig. 8) input from the operation panel 46 (see fig. 7). When the OK button on the operation panel 46 is operated, the preliminary cleaning history creation unit 86 (see fig. 7) associates the preliminary cleaning execution information Y12 displayed on the display on the operation panel 46 with the preliminary cleaning identification information Y11 to create a preliminary cleaning history Y1 (see fig. 8) (S12). Under the control of the pre-cleaning controller 47, the pre-cleaner communication unit 87 transmits the pre-cleaning history Y1 to the endoscope management server 25.
Upon receiving the pre-cleaning history Y1, the cleaning history management unit 101 determines whether or not the endoscope cleaning history 67 having the endoscope identification information common to the pre-cleaning identification information Y11 is stored in the endoscope cleaning history DB 68. Then, the endoscope cleaning history 67 is created and updated based on the determination result (S13).
When it is determined that the endoscope cleaning history 67 having the endoscope identification information common to the received pre-cleaning history Y1 is not stored in the endoscope cleaning history DB68, the cleaning history management unit 101 creates the pre-cleaning history Y1 as the endoscope cleaning history 67 and stores the endoscope cleaning history DB 68. When it is determined that the endoscope cleaning history 67 having the endoscope identification information common to the received pre-cleaning history Y1 is stored in the endoscope cleaning history DB68, the cleaning history management unit 101 adds the pre-cleaning execution information Y12 in the pre-cleaning history Y1 to the endoscope cleaning history 67 (see fig. 10) stored in the endoscope cleaning history DB68, and updates the endoscope cleaning history 67 (see fig. 12).
According to the present invention, since the pre-cleaning identification information Y11 and the pre-cleaning execution information Y12 can be input immediately after the pre-cleaning, even when the pre-cleaning and the main cleaning are performed in a non-consecutive manner, or even when the pre-cleaning person and the main cleaning person are different persons, it is possible to prevent the pre-cleaning history from being input erroneously as "the pre-cleaning execution is completed" or input erroneously in spite of the endoscope that has not been pre-cleaned. Therefore, according to the present invention, it is possible to create a washing history reflecting actual pre-washing content, and further, to perform effective history management.
In fig. 13, at the time of main washing, the foot switch 58 is operated to move the upper cover 23C to the open position. The electronic endoscope 12 that has been cleaned in advance is placed in the cleaning tank 50 and placed on the support frame 51N (see fig. 5) (S21). The upper cover 23C is returned to the closed position by the foot switch 58. The main wash controller 55 reads endoscope identification information from the electronic endoscope 12 mounted on the support frame 51N via the tag reader 60 (see fig. 7) (S22).
When the operation panel 54 is operated to input the contents of main wash, the main wash controller 55 causes the display on the operation panel 46 to display main wash execution information Y22 (see fig. 9). When the start button 54C is operated, the main wash controller 55 transmits the endoscope identification information to the endoscope management server 25 via the transmission section 92S (S23).
The determination unit 103A (see fig. 7) searches the endoscope cleaning history DB68 (see fig. 7) for the endoscope cleaning history 67 (see fig. 10) having the same endoscope identification information as the received main cleaning identification information Y21. It is determined whether or not the endoscope cleaning history 67 searched for contains the individual pre-cleaning execution information Y12. When it is determined that the individual pre-wash execution information Y12 (see fig. 12) is included, main wash control unit 103C outputs a main wash start permission signal to main washer 23 (yes in S24).
Upon receiving the main cleaning start permission signal from the endoscope management server 25, the cleaning unit 94 performs main cleaning of the electronic endoscope 12 placed on the support frame 51N (S25). After the main wash is completed, the main wash history creation unit 91 (see fig. 7) creates a main wash history Y2 (see fig. 9) by associating the endoscope identification information read by the tag reader 60 as main wash identification information Y21 with the main wash execution information Y22 stored in the memory of the main washer 23 (S26). The transmission unit 92S transmits the created main cleaning history Y2 (see fig. 9) to the endoscope management server 25.
Upon receiving the main cleaning history Y2, the cleaning history management unit 101 searches the endoscope cleaning history DB68 for the endoscope cleaning history 67 having the endoscope identification information common to the main cleaning identification information Y21. Then, the cleaning history management unit 101 supplements the main cleaning execution information Y22 to the endoscope cleaning history 67 thus searched, and makes a pair with the individual pre-cleaning execution information Y12. In this way, the endoscope cleaning history 67 is updated (S27).
When it is determined in step S24 that the individual pre-cleaning execution information Y12 is not included in the endoscope cleaning history 67, the warning control unit 103B transmits a warning request signal to the main cleaning machine 23 (no in S24). In response to this, the main-washing control unit 103C may transmit a main-washing start prohibition signal to the main washing machine 23. When the warning request signal from the endoscope management server 25 is received by the display driver 93, a warning screen (see fig. 13) based on the warning screen information stored in the memory of the main washer 23 is output to the display 54B (S35).
In the warning screen, the electronic endoscope 12 placed in the main washer 23 is warned that the pre-washing has not been performed. In addition, the display unit of the electronic endoscope 12 placed in the main washer 23 may be notified that the pre-washing is to be performed. Note that either one of the former warning and the latter warning or both of them may be reported.
In the present invention, it is determined whether or not the electronic endoscope 12 set in the main washer 23 has been precleaned, and if it is determined that precleaning has not been performed, it is warned that precleaning should be performed without starting main washing, so that it is possible to prevent the precleaning from being performed without fail.
The endoscope cleaning history DB68 stores the endoscope cleaning history 67 shown in fig. 10, but may store the pre-cleaning history Y1 and the main cleaning history Y2 shown in fig. 8. In this case, the endoscope cleaning history DB68 functions as a pre-cleaning history storage unit, an endoscope cleaning history storage unit, and a main cleaning history storage unit.
In the above embodiment, the determination unit 103A determines whether or not the read endoscope cleaning history 67 includes an individual pre-cleaning history (specifically, the pre-cleaning execution information Y12), but instead, may determine whether or not the latest pre-cleaning history among the read endoscope cleaning histories 67 is an individual pre-cleaning history.
Next, the output of the cleaning history information will be described. As shown in fig. 7, the cleaning history output request unit 110 outputs a cleaning history output request signal to the endoscope management server 25 by operating the operation terminal 26. The cleaning history management unit 101 reads the endoscope cleaning history 67 based on the received cleaning history output request signal from the endoscope cleaning history DB68, and transmits a print request signal to the printer 27 (see fig. 1). The printer 27 that has received the print request signal prints the endoscope cleaning history 67 based on the print request signal. The ith pre-cleaning history and the ith main cleaning history are stored in the endoscope cleaning history 67 in pairs. By the operation through the operation terminal 26, the endoscope cleaning history 67 can be printed as a cleaning history. In the printed cleaning histories, the ith pre-cleaning history and the ith main cleaning history are paired. Such a cleaning history is more reliable than a conventional cleaning history composed of only the main cleaning history.
Further, the endoscope cleaning history 67 may be displayed on the display of the operation terminal 26 by operating the operation terminal 26.
In the above embodiment, the IC tag 30TG provided in the electronic endoscope 12 is of a ROM type that can only read endoscope identification information stored in advance, but may be of a RAM type that can write new information in addition to endoscope identification information stored in advance. The new information includes pre-cleaning execution information, pre-cleaning history, main cleaning execution information, main cleaning history, and the like. In addition, when the cleaning history information is stored in the IC tag 30TG, the endoscope cleaning history DB68 may be omitted.
In the above embodiment, the CPU of the precleaner 22 is caused to function as the precleaning history creation unit 86, but instead, the CPU of the main washer 23 or the endoscope management server 25 may be caused to function as the precleaning history creation unit 86. Similarly, the CPU of the main washing machine 23 is caused to function as the main washing history creation unit 91, but instead, the CPU of the pre-washing machine 22 or the endoscope management server 25 may be caused to function as the main washing history creation unit 91.
Further, the precleaner 22 and the main washer 23 may be provided with an airtight test port for sending compressed air to each passage to test whether or not a hole or crack is formed in the passage. The preliminary cleaning execution information and the main cleaning execution information may include the result of the air-tightness test.
The pre-washing history creating unit 86 may read the name of the pre-washing operator by using a reading means provided in the pre-washing machine 22, in addition to reading the name of the pre-washing operator based on the operation signal from the operation panel 46. Similarly, the main cleaning history creation unit 91 may read the name of the main cleaning performer using a reading means provided in the main cleaning machine 23. As the reading means provided in the pre-washing machine 22 and the main washing machine 23, there are a barcode reader capable of reading the name of the washing performer from a barcode indicating the name of the washing performer, a tag reader capable of reading the name of the washing performer from an IC tag in which the name of the washing performer is stored, and the like, and any of them may be used.
The pre-washing machine 22 is provided with the tag reader 45, but the tag reader 45 electrically connected to the main washing machine 23 (e.g., the main washing controller 55) may be disposed in the vicinity of the pre-washing machine 22. The tag reader 45 may be detachably provided in the pre-washing machine 22. Similarly, an operation panel 46 electrically connected to the main washer 23 (e.g., the main wash controller 55) may be disposed near the pre-washer 22. The main washer 23 may be detachably provided in the pre-washer 22.
In the above embodiment, the precleaner 22 including the water tank 41 for precleaning and the members 45 to 46 provided near the water tank 41 is used, but the present invention is not limited thereto, and a water tank unit 121 including the water tank 41 (see fig. 14) may be used. When the water tank unit 121 is used, it is preferable that the pre-cleaning history unit 122 including the respective members 45 to 47 be provided in the vicinity of the water tank unit 121 so as to be capable of communicating with the endoscope management server 25 via a network.
Instead of the pre-cleaning history unit 122 in which the respective members 45 to 47 are integrated, the respective members 45 to 47 may be provided in the vicinity of the water tank 41.
