The tag information acquisition unit acquires the tag information transmitted from the non-contact tag reader 100 and the read time information together with the medical worker ID information. The terminal control unit controls processing of the non-contact tag reader 100 or the portable electronic medical record terminal 600 based on the tag information acquired from the non-contact tag reader 100 and the read time information. Details of the in-hospital hand washing monitoring server 400 will be described later.

  The electronic medical record server (medical information storage means) 500 is a server that manages the portable electronic medical record terminal 600. The electronic medical record server 500 is configured to transmit patient information to the portable electronic medical record terminal 600 held by the medical staff when the medical staff appropriately performs hand washing and disinfection in the in-hospital hand washing monitoring server 400.

  The portable electronic medical record terminal (medical information display means) 600 is a portable information processing terminal that displays patient information regarding a patient transmitted from the electronic medical record server 500. The portable electronic medical chart terminal 600 is usually held by a medical worker. For example, when the hand washing situation of the medical worker satisfies a predetermined condition, the patient information can be displayed. When the condition is not satisfied, a warning for washing hands is given to a medical worker carrying the portable electronic medical chart terminal 600.

  The network 700 is a network for connecting devices and servers connected to the in-hospital hand washing management system 800 to each other.

  Next, an overall outline operation of the in-hospital hand-washing management system 800 according to the present embodiment will be described using a sequence diagram.

  FIG. 2 is a sequence diagram showing an overall schematic operation of the in-hospital hand-washing management system 800 according to the present embodiment.

  First, it is assumed that a medical worker such as a doctor or a nurse carries the non-contact tag reader 100 and the portable electronic medical record terminal 600.

  The non-contact tag reader 100 reads RFID tag information provided on the non-contact tag 200 from the non-contact tag 200 (step S001). Here, it is assumed that the non-contact tag 200 having the patient registration information related to the patient is read and the tag information indicating the patient registration information is read from the RFID.

  The non-contact tag reader 100 transmits the read tag information of the non-contact tag 200 to the wireless access point 300 via the network 700 together with the medical worker ID information (step S003). Further, the non-contact tag reader 100 transmits not only the read tag information but also time information when the tag information is read.

  The wireless access point 300 receives the tag information of the non-contact tag 200, the time information obtained by reading the tag information, and the ID information of the medical staff through the network 700, and also monitors the in-hospital hand-washing through the network 700. The tag information, the time information at which the tag information is read, and the ID information of the medical staff are transmitted to the server 400 (step S005).

  The in-hospital hand washing monitoring server 400 executes hand washing monitoring processing based on the acquired tag information and the time information when the tag information is read (step S007). Here, the in-hospital hand-washing monitoring server 400 determines whether or not the medical staff has performed sufficient hand-washing by executing the hand-washing monitoring process. If it is determined that the hand-washing has been performed sufficiently, it is obtained from the non-contact tag 200. The tag information and the medical worker ID information are transmitted to the electronic medical record server 500 (step S009).

  Then, the electronic medical record server 500 acquires the transmitted tag information and the medical staff ID information, and based on the patient unique identifier (Patient Identification: patient ID) associated with the acquired tag information, The patient information is read, and the patient information is transmitted to the portable electronic medical chart terminal 600 associated with the medical worker ID information (step S011).

  Thereby, the portable electronic medical record terminal 600 can receive the patient information transmitted from the electronic medical record server 500, and performs a patient information switching process.

  Thus, since the portable electronic medical chart terminal 600 can acquire the patient information associated with the non-contact tag 200 by reading the non-contact tag 200 with the non-contact tag reader 100, the portable electronic medical record terminal 600 is associated with the non-contact tag 200. The displayed patient information can be switched to the displayed patient information. Thereby, the medical staff can browse the patient information of the portable electronic medical chart terminal 600 in a state where it is determined that the hand washing is sufficiently performed, or can input the treatment record of the patient to the portable electronic medical chart terminal 600.

  On the other hand, the in-hospital hand-washing monitoring server 400 may transmit warning information to the medical staff by two types of methods when it is determined that the medical staff is not performing hand-washing sufficiently by executing the hand-washing monitoring process. it can.

  In the first method, the in-hospital hand-washing monitoring server 400 transmits warning information that prompts hand-washing to the non-contact tag reader 100 that has transmitted the tag information of the non-contact tag 200.

Warning information for prompting hand washing is transmitted to the tag reader 100 (step S015).

  The non-contact tag reader 100 receives warning information for prompting hand-washing from the in-hospital hand-washing monitoring server 400 by the warning information receiving unit 130 and displays the received warning information for prompting hand-washing on the warning information display unit 140, thereby Notification that hand washing is not sufficient.

  As another method, the in-hospital hand-washing monitoring server 400 transmits warning information for prompting hand-washing to the electronic medical record server 500 via the network 700 (step S017).

  When the electronic medical record server 500 receives warning information prompting hand washing, the electronic medical record server 500 searches for ID information of a medical worker associated with the non-contact tag reader 100, and stores the hand washing in the portable electronic medical record terminal 600 carried by the medical worker. Warning information for prompting is transmitted (step S019).

  In this case, the electronic medical record server 500 notifies the portable electronic medical record terminal 600 that the hand of the medical worker is not sufficient, and for example, the portable electronic medical record terminal 600 cannot be operated. Limits can also be applied.

  As described above, the portable electronic medical chart terminal 600 receives the warning information for prompting hand washing and disinfection from the in-hospital hand washing monitoring server 400, and displays the received warning information for prompting hand washing on the display unit. The medical staff carrying the medical chart terminal 600 can be notified that the hand washing of the medical staff is not sufficient.

A contact tag reader RD10 is attached to a wrist or the like.

  Thereby, in this embodiment, when any non-contact tag which comprises the non-contact tag 200 is read by non-contact tag reader RD10 which medical worker HC10 carries, wireless access point 300 (FIG. 1 etc.) The tag information read is transmitted to the in-hospital hand-washing monitoring server 400 (such as FIG. 1) via the network 700 (such as FIG. 1).

  In addition, among this embodiment, embodiment in hospital room HR100 is described as 1st Embodiment. Further, an embodiment using a portable disinfectant bottle CL20 carried by the medical staff HC10 will be described as a second embodiment. An embodiment related to entering the hospital room HR100 will be described as a third embodiment.

(First embodiment)
Next, the operation of the in-hospital hand washing monitoring server 400 according to the first embodiment will be described with reference to FIGS. 1 to 3 and FIG.

(Hand washing monitoring process)
FIG. 6 is a flowchart showing the operation of the hand washing monitoring process performed by the in-hospital hand washing monitoring server 400 (FIG. 1) in the in-hospital hand washing management system 800 (FIG. 1) according to the first embodiment. In FIG. 6, reference numerals with numerals added to S indicate steps of the flowchart.

  In the first embodiment, in the hospital room HR100 of FIG. 5, it was recorded that the medical worker HC10 washed hands in the vicinity of the non-contact tag TG13 installed in the hand washing place HW40 installed in the hospital room HR100. When the medical worker HC10 performs treatment on the body of the patient P, the non-contact tag TG10 mounted on a part of the patient P or the non-contact tag TG11 installed on the bed SB11 used by the patient P is used. The operation of processing when reading is described.

  In the hand-washing monitoring process, the medical staff HC10 reads any non-contact tag in order to start the treatment for the patient P, and according to the result, the treatment for the patient P is performed in the hospital room HR100. It shall be determined whether to obtain.

  As shown in step S005 of FIG. 2, when the in-hospital hand-washing monitoring server 400 acquires tag information of the non-contact tag 200 from the wireless access point 300 via the network 700 (step S101), the acquired tag information Determine the type.

  For example, the in-hospital hand-washing monitoring server 400 determines whether or not the acquired tag information is hand-washing record information (step S103), and if the acquired tag information is hand-washing record information (step S103). YES), the tag information acquisition unit 410 records the tag information for each medical staff in the hand-washing record information database 420 (step S105).

  In this case, the tag information acquisition unit 410 records the handwash start time when the medical worker HC10 washed his hand and the time when the hand was washed for each medical worker as handwash record information.

  Then, the terminal control unit 440 of the in-hospital hand-washing monitoring server 400 determines the hand-washing time during which the medical worker HC10 was washing hands near the non-contact tag TG13 installed in the hand-washing place HW40. It is determined whether or not the health care worker HC10 has performed sufficient hand washing depending on whether or not the hand has been washed for a predetermined time (for example, 30 seconds) (step S107).

  Specifically, the medical staff HC10 reads the non-contact tag TG13 twice before the start of hand washing and after the end of hand washing. And since the terminal control part 440 of the in-hospital hand-washing monitoring server 400 can calculate the time when the hand was washed by hand-washing record information based on the hand-washing start time and the hand-washing end time, sufficient hand-washing (for example, It can be determined whether or not hand washing for 30 seconds or more has been performed.

  Here, if the hand washing time recorded in the acquired tag information is less than the predetermined time, the terminal control unit 440 determines that the medical worker HC10 is not performing sufficient hand washing due to the short hand washing time. (NO in step S107), warning information for prompting hand washing is transmitted to the non-contact tag reader 100 via the wireless access point 300 (step S113), and the hand washing monitoring process is terminated.

  On the other hand, if the hand washing time recorded in the acquired tag information is equal to or longer than the predetermined time, it is determined that the health care worker HC10 has performed sufficient hand washing because the hand washing time is long (YES in step S107), Returning to step S101, the medical staff HC10 can perform treatment on the patient P in the hospital room HR100.

  On the other hand, when the acquired tag information is not hand-washing record information (NO in step S103), the tag information acquisition unit 410 determines that the information is patient registration information, and registers the acquired tag information for each medical staff. The information is recorded in the information database 430 (step S109). In this case, the tag information acquisition unit 410 records information on the time when the non-contact tag reader 100 of the medical worker HC10 reads the non-contact tag TG10 of the patient P who receives treatment in the hospital room HR100 for each medical worker.

  The terminal control unit 440 of the in-hospital hand washing monitoring server 400 compares the time when the non-contact tag TG10 of the patient P is read with the latest time when the health care worker HC10 washed hands (the time when the hands were washed last). Thus, it is determined whether or not hand washing of the health care worker HC10 is sufficient. For example, within a predetermined time (for example, 30 minutes) after the health care worker HC10 finally washes the hand, the patient P is not in contact with the hand. Depending on whether or not the patient registration information of the tag TG10 has been read, the medical worker HC10 determines whether or not hand washing is necessary (step S111).

  When the terminal control unit 440 obtains the patient registration information and the hand washing record information of the last hand wash, if more than 30 minutes have passed since the last hand wash, the medical worker HC 10 It is determined that it is necessary (YES in step S111), warning information for prompting hand washing is transmitted to the non-contact tag reader 100 via the wireless access point 300 (step S113), and the hand washing monitoring process is terminated.

  On the other hand, if the hand washing record information of the last hand washing has not passed a predetermined time (for example, 30 minutes), the terminal control unit 440 determines that the medical worker HC10 does not need to wash hands ( NO in step S111), the process returns to step S101, and the medical worker HC10 can perform treatment on the patient P in the hospital room HR100.

  As described above, in the in-hospital hand-washing monitoring server 400 according to the first embodiment, the terminal control unit 440 determines tag information of the non-contact tag 200, and the medical worker HC10 performs hand-washing based on the tag information. If it is necessary to wash the hand, warning information for prompting hand washing is transmitted to the non-contact tag reader 100 and the medical worker HC10 is notified that hand washing is necessary. .
