Description

MANAGEMENT SYSTEM FOR CLEANING AND DISINFECTION OF ENDOSCOPES BASED ON NEAR FIELD COMMUNICATION

The present invention relates to an endoscope scope cleaning and disinfection control system, and more specifically, an endoscope scope using NFC for automatically operating an operation method of cleaning and disinfecting an endoscope scope that was previously recorded and managed by hand using NFC. It relates to a cleaning and disinfection control system.

Endoscopy is more accurate than sham imaging, contributing greatly to early detection of diseases such as cancer. For example, the gastroscopic scope is a long and thin electronic device that is inserted into the esophagus through the mouth of the examinee to photograph the subject's stomach.

The problem is that if a contaminated instrument comes into contact with the mucous membrane of the subject, a fatal infection can occur. This is because, if the scope used on a patient infected with tuberculosis, hepatitis B, hepatitis C, or AIDS is used on another person without proper reprocessing, there is a high possibility of transmission of pathogens through the mucous membrane.

Infections caused by the careless microvessel use of an endoscopic scope can occur in all types of endoscopic examinations, not just gastroscopy. According to academia, most of the confirmed causes of infection accidents of endoscope scopes are due to the failure of disinfection of instruments. Compared to Korea, it is estimated that the number of infections and deaths due to endoscopy is higher than is known, as it is difficult to determine the exact number even in developed countries with a systematic infection control system.

In the disinfection and management of the endoscope scope, the personnel in the hospital perform cleaning and disinfection and manually record the cleaning and disinfection time, time, and end time, etc. It is difficult to do so, and if the person in charge incorrectly writes the unique number of the endoscope scope, there is a very high possibility that it will lead to a serious infection accident.

Therefore, there is a need for an automated endoscopic scope cleaning record operating system that can precisely track all processes related to cleaning and disinfection of the endoscopic scope.

As shown in Figure 1, the endoscope scope cleaning and disinfection control system 10 according to the present invention, the endoscope scope 100, including the first NFC tag 110 and the object of cleaning and disinfection, the first NFC of the endoscope scope NFC reader 200 for reading information from the tag, the gateway device 300 for transmitting the information read from the NFC reader 200 to the hospital management server 500, and cleaning and disinfection of the endoscope scope 100 It includes a server 500 in the hospital where information is stored.

A first NFC tag 110 in which identification information of the endoscope scope is stored is provided in the body of the endoscope scope 100 . The first NFC tag 110 includes ID data that can identify the endoscope scope 100, and the ID data is read by the NFC reader 200 and the NFC reader 200 sends the read NFC information to the hospital. It is transmitted to the server 500 through the gateway device 300 installed in the.

NFC (Near Field Communication) belongs to RFID, a standard technology for short-range wireless communication technology, and refers to a non-contact data exchange technology between terminals up to 10 cm in frequency band of 13.56Mhz.

NFC supports bidirectional communication capable of reading and writing information. Unlike a smart card that only serves as a tag that stores specific information and transmits it to a reader, NFC can serve as a reader/writer that reads or writes tag information as well as a tag if necessary. As such, NFC developed based on RFID technology has a slower data transmission speed compared to other methods such as Bluetooth and Zigbee used for short-distance communication, but has a shorter communication setup time and fewer malfunctions in recognition. There are many advantages such as

In this regard, the first NFC chip or tag 110 provided on the body of the endoscopic scope 100 may be exposed to strong water pressure and PH concentration disinfectant solution inside the washer and sterilizer due to the nature of the environment of use. It is preferable to be made of a silicon material, and it is preferable to maintain a tag outer shape of 4 mm in thickness and a surface separation distance of 3 mm or more so as not to lose frequency characteristics on the metal surface of the endoscope scope 100.

In addition, it is preferable that the first NFC tag is attached to the body of the endoscope scope 100 by avoiding a metal cross section, and when contact with the metal end surface of the scope is unavoidable, an NFC tag to which a shielding sheet or the like is attached is preferably used. .

As shown in FIG. 3, the user interface includes an interface for receiving identification information of the endoscope scope and the washing/disinfecting machine, a status check interface for checking the washing/disinfecting history of the endoscope scope, and the start time and end time of washing/disinfection. It consists of an interface for input.

A user can select a desired operation through a screen of the user interface. For example, if the user selects the screen interface for reading the endoscope scope and the washer/disinfector, the user can read the respective ID information by bringing the NFC tag of the endoscope scope and the NFC tag of the cleaner/disinfector to the NFC reader. .

In addition, when the user selects the status check screen interface and brings the NFC tag of the endoscope scope close to the NFC reader, the control unit searches the database for the use record of the endoscope scope with the ID corresponding to the server, and then returns the searched history information to the user's NFC reader. By displaying it on the screen of , the user can inquire the use history information including the cleaning and disinfection history of the endoscope scope.

In addition, when the user selects the washing/disinfection start screen interface, the control unit additionally provides a screen interface for the user to manually input the washing and disinfection start time, or the control unit inquires the internal time information of the NFC reader to perform cleaning and disinfection. The disinfection start time is automatically recorded in the memory.

In addition, if the user selects the cleaning/disinfection end screen interface, the control unit additionally provides a screen interface for the user to manually input the cleaning and disinfection end time, or the control unit inquires the internal time information of the NFC reader to perform cleaning and disinfection. The disinfection end time is automatically recorded in the memory.

In addition, when the user selects the transmission screen interface, the control unit transmits the information including the ID information of the endoscope scope stored in the memory, the ID information of the washer and sterilizer, the start time and end time of cleaning and disinfection, and the user ID information through the communication unit. sent to the gateway.

The server 500 is installed inside the hospital or outside the hospital, receives the cleaning and disinfection related information delivered through the gateway 300, and records it in the database. Specifically, when the server 500 receives the cleaning and disinfection related information, based on the identification information of the corresponding endoscope scope from the information data, the server 500 inquires from the database and updates the cleaning and disinfection related information of the corresponding endoscope scope 10 .

The information updated in the database includes the ID information of the device that cleaned and disinfected the corresponding endoscope scope 100, the year, month, and date of cleaning and disinfection, the cleaning and disinfection start time, the cleaning and disinfection end time, and the ID of the user who performed the cleaning and disinfection. , the usage count information is updated.

The information stored in the database as described above can be inquired by a mobile terminal including an NFC reader or a smart phone, a smart pad, or a fixed terminal such as a personal computer and a laptop computer, and thus the user responsible for cleaning and disinfecting the endoscope in the hospital can monitor the status of the endoscope scope regardless of time and place.
