Description

The present invention relates to a hand hygiene management system, and in particular, a hand hygiene management system that detects that a discharge operation has been performed on a disinfectant container that discharges a disinfectant solution and manages the execution status of hand hygiene by a medical worker. It is suitable for use in.

WHO warns about the five stages of pathogen transmission that occur through the hands of medical personnel among medical-related infections, and through guidelines, such as hand washing with soap and running water and hand disinfection with alcohol disinfectants. Enforcement of hand hygiene is recommended. However, many medical institutions have a hand hygiene implementation rate of less than 50%, and the compliance rate is not high.

Therefore, it is required to improve the compliance rate of hand hygiene by sensing the actual condition of whether or not the medical staff is performing hand hygiene at the required timing and feeding back the result to the site. Against this background, by detecting that a discharge operation has been performed on a disinfectant bottle that discharges disinfectant liquid and transmitting predetermined information, disinfection results by medical professionals based on the information have been performed. A system for managing the above has been proposed (see, for example, Patent Documents 1 and 2).

In the disinfection record grasping system described in Patent Document 1, a container with a disinfection pump (disinfection bottle) is located around the disinfection bottle based on the discharge operation detection means for detecting the discharge operation and the detection of the discharge operation. It is provided with a discharge completion signal transmitting means for transmitting a discharge completion signal to a name plate (incorporating a communication unit, a control microcomputer, and a storage medium) carried by a managed person (medical worker). Further, the name plate includes a storage medium for storing information on the disinfection record by the managed person, and an updating means for updating the disinfection record information based on the received discharge completion signal.

In the in-hospital hand-washing management system described in Patent Document 2, a pressing force on the nozzle head is applied to a rubbing alcohol bottle (rubbing bottle) provided with a nozzle head that discharges rubbing alcohol from a discharge nozzle by a pump mechanism by pressing. A hand-washing management device including a pressure sensor that detects the pressure sensor and a communication device that transmits the pressure value detected by the pressure sensor together with its own communication device ID is attached, and a disinfecting bottle equipped with the hand-washing management device is specified in the hospital. Place it in a place and install a repeater within the range where it can communicate with the communication device of the disinfection bottle with a hand-washing management device. In addition, the medical staff is made to carry a personal ID transmitter that transmits the personal ID at regular time intervals. The repeater receives the personal ID, the communication device ID, and the pressing value from the communication device of the hand-washing management device, and transmits these information to the in-hospital server together with the repeater ID unique to the repeater. The in-hospital server compares the personal ID and the pressing value received from the repeater with the personal information held by the in-hospital server and the predetermined pressing setting value, and the nozzle head is not pushed or pushed for each individual. Is inadequate or has been pushed sufficiently. In addition, the location of the medical staff is specified by comparing the repeater ID with the position information of the repeater that the in-hospital server has inside. Then, the in-hospital server causes the recording device to record those results.

According to the technique described in Patent Document 2, not only whether or not the hand hygiene is performed by the medical staff, but also whether or not the nozzle head is sufficiently pushed (that is, whether or not the amount of rubbing alcohol discharged is sufficient). It is possible to manage up to). On the other hand, it is also required to manage whether or not the number of times of hand hygiene is sufficient.

In response to such a request, in the system described in Patent Documents 1 and 2, if the number of times the disinfection bottle discharge operation is detected is counted, it is possible to grasp the number of times the medical staff has performed hand hygiene. It is possible. However, if the discharge operation of the disinfectant bottle is simply counted, there is a problem that the number of times of hand hygiene may not always be accurately grasped. The medical staff pushes the nozzle head little by little in multiple steps, re-operates when the push operation is unintentionally insufficient, and multiple push operations when the remaining amount of disinfectant is low. This is because they may go around.

The present invention has been made to solve such a problem, and an object of the present invention is to enable a more accurate grasp of the number of times hand hygiene has been performed by a medical worker.

In order to solve the above-mentioned problems, in the present invention, the information transmitted from the discharge operation detection device provided in the disinfection container for discharging the disinfectant solution to the management device via the relay device and carried by the medical staff. Of the information periodically transmitted from the wireless transmission device to the management device via the relay device, the operation execution information, the detection device ID, and the medical worker ID received together with the same relay device ID within a predetermined minute time. Based on this, after identifying the medical staff who operated the disinfection container, the number of times of hand hygiene is measured for each medical staff. Then, when the operation of the disinfection container by the same medical staff is detected multiple times within a predetermined time during the measurement of the number of executions, the multiple operations within the predetermined time are performed once for hand hygiene. It is regarded as execution and the number of executions is measured.

According to the present invention configured as described above, even if the same medical worker operates the disinfectant container multiple times, if the multiple operations are performed within a predetermined time, the operation is performed. It is highly probable that one medical worker has performed the ejection operation in a plurality of times in one hand hygiene, and the number of times the hand hygiene is performed is measured. Thereby, according to the present invention, it is possible to more accurately grasp the number of times the hand hygiene is performed by the medical staff.

It is a figure which shows an example of each apparatus provided in the hand hygiene management system by this embodiment, and the place of installation thereof. It is a block diagram which shows the functional structure example of the management apparatus by this Embodiment. It is a figure which shows an example of the received information stored in the received information storage part of this embodiment. It is a figure which shows an example of the received information stored in the received information storage part of this embodiment.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an example of each device provided in the hand hygiene management system according to the present embodiment and their installation location. In the following embodiment, the facility to which the hand hygiene management system is applied will be described as a hospital, but it can be applied to any facility where the enforcement of hand hygiene is recommended, such as a long-term care facility. be.

As shown in FIG. 1, the hand hygiene management system according to the present embodiment is a disinfection bottle 10 (corresponding to a disinfection container within the scope of claims. In FIG. 1, it is simply referred to as “bo”. The discharge operation detection device 100 provided in the), the wireless transmission device 200 carried by a medical worker, and the relay device 300 installed at each location in the hospital (simply referred to as "middle" in FIG. 1). (Notated) and a management device 400 connected to the relay device 300 via a communication network.

As shown in FIG. 1, the disinfectant bottle 10 is installed in, for example, each hospital room R1, R2, R3 in a hospital. The position in the hospital room R1, R2, R3 where the disinfection bottle 10 is installed is, for example, near the doorway. Alternatively, it may be located near the bed in the hospital room. The position where the disinfectant bottle 10 is installed may be a position outside the hospital room (corridor CR) near the entrance / exit of each hospital room R1, R2, R3.

When the disinfectant bottle 10 is installed in the hospital room R1, R2, R3, the medical staff performs hand hygiene immediately after entering the hospital room R1, R2, R3, and also performs hand hygiene immediately after the work is completed. Just before leaving the room from R3, hand hygiene will be performed again. On the other hand, when the disinfection bottle 10 is installed in the corridor CR near the entrance / exit of the hospital rooms R1, R2, R3, the medical staff performs hand hygiene immediately before entering the hospital rooms R1, R2, R3, and also performs work. Immediately after leaving the hospital rooms R1, R2, and R3 after the completion, hand hygiene will be performed again.

As the disinfection bottle 10, in addition to the stationary type installed in the hospital rooms R1, R2, and R3 as shown in FIG. 1, there is a portable type possessed by a medical worker. Medical professionals who have a portable disinfection bottle 10 also basically perform hand hygiene immediately after entering the hospital rooms R1, R2, and R3 (or immediately before entering the room), and after the work is completed. Hand hygiene is performed again immediately before (or immediately after) leaving the hospital rooms R1, R2, and R3.

As shown in FIG. 1, the disinfectant bottle 10 is a pump-type bottle, and a constant amount of the disinfectant liquid in the bottle is discharged by pressing the upper nozzle head downward. A discharge operation detection device 100 is attached to this nozzle head. The discharge operation detection device 100 includes a pressure sensor, and detects that a discharge operation (nozzle head pressing operation) has been performed on the disinfecting bottle 10. This is the same for both the stationary disinfection bottle 10 and the portable disinfection bottle 10.

The discharge operation detection device 100 includes a wireless transmission circuit, and when the discharge operation for the disinfectant bottle 10 is detected by the pressure sensor, the operation execution information indicating that the discharge operation has been executed is obtained by its own identification information. It is transmitted wirelessly together with a certain detection device ID. The detection device ID is identification information unique to the discharge operation detection device 100, and is stored in advance in the internal memory.

The operation execution information and the detection device ID transmitted from the discharge operation detection device 100 mounted on the stationary disinfection bottle 10 are transmitted to the relay device 300 installed in the same space as the stationary disinfection bottle 10. Is received. Further, the operation execution information and the detection device ID transmitted from the discharge operation detection device 100 mounted on the portable disinfection bottle 10 are received by the relay device 300 around the position where the medical staff is present. Will be done.

The wireless transmission device 200 carried by the medical worker periodically transmits the medical worker ID, which is the identification information of the medical worker, at predetermined intervals. For example, the wireless transmission device 200 transmits a medical worker ID at a minute time interval of 200 milliseconds. The medical worker ID is identification information unique to the medical worker and is stored in advance in the internal memory of the wireless transmission device 200. The medical worker ID transmitted by the wireless transmission device 200 is received by the relay device 300 around the position where the medical worker is present.

The relay device 300 is installed in each hospital room R1, R2, R3 which is the same space as the stationary disinfection bottle 10, and is also installed in a space different from the stationary disinfection bottle 10. The space different from the stationary disinfection bottle 10 means a place other than each hospital room R1, R2, R3, and is a corridor CR in the example of FIG.

The relay device 300 receives the operation execution information and the detection device ID from the discharge operation detection device 100 of the disinfection bottle 10, and also receives the medical worker ID from the wireless transmission device 200, and is connected via a communication network. The received information is transmitted to the device 400 together with the relay device ID which is its own identification information. The relay device ID is identification information unique to the relay device 300 and is stored in advance in the internal memory.

Here, the relay device 300 specifies the relative position of the discharge operation detection device 100 from the relay device 300 based on the received radio wave when the operation execution information and the detection device ID are received from the discharge operation detection device 100. For example, the relay device 300 specifies the relative direction of the discharge operation detection device 100 by using a known technique for detecting the direction in which the radio wave arrives by the AoA (Angle of Arrival) method, and the radio wave transmission source is based on the received radio wave strength. By specifying the relative distance to the discharge operation detection device 100 by using a known technique for detecting the distance to the discharge operation detection device 100, the relative position of the discharge operation detection device 100 from the relay device 300 is specified. Then, the relay device 300 transmits the relative position information of the specified discharge operation detection device 100 to the management device 400 together with the operation execution information, the detection device ID, and the relay device ID.

Further, the relay device 300 specifies the relative position of the wireless transmission device 200 in the same manner as described above, based on the received radio wave when the medical worker ID is received from the wireless transmission device 200. Then, the relay device 300 transmits the relative position information of the specified wireless transmission device 200 to the management device 400 together with the medical worker ID and the relay device ID.

The management device 400 receives the operation execution information, the detection device ID, the medical worker ID, and the relative position information of the discharge operation detection device 100 received from the relay device 300 together with the same relay device ID within a predetermined minute time (200 milliseconds). In addition, based on the relative position information of the wireless transmission device 200, the medical staff who operated the disinfecting bottle 10 is specified, and then the medical staff manages the execution status of hand hygiene. For example, the management device 400 performs a process of measuring which medical worker performs hand hygiene how many times. The details of this process will be described with reference to FIG.

As described above, the wireless transmitter 200 constantly transmits the medical worker ID every 200 milliseconds. Therefore, when the relay device 300 receives the operation execution information and the detection device ID from the discharge operation detection device 100, the wireless transmission device 200 is at substantially the same timing (within a time lag within 200 milliseconds at most). The medical worker ID will also be received from. As a result, the management device 400 receives the information from the discharge operation detection device 100 and the information from the wireless transmission device 200 (including the information added by the relay device 300, respectively) from the relay device 300 at substantially the same timing. From this information, it is possible to identify the health care worker who performed hand hygiene.

On the other hand, when the relay device 300 receives the medical worker ID from the wireless transmission device 200, but does not receive the operation execution information and the detection device ID from the discharge operation detection device 100 within a predetermined minute time. The management device 400 receives only the information from the wireless transmission device 200 (including the information added by the relay device 300) from the relay device 300 within a predetermined minute time. Therefore, in this case, the management device 400 can determine that the medical staff is not performing hand hygiene within the minute time.

Here, the operation execution information received together with a certain relay device ID and the medical worker received together with the same relay device ID within a predetermined minute time from the time of the operation of the disinfection bottle 10 detected based on the detection device ID. When there is only one ID, it corresponds to a situation where there is only one medical worker in the vicinity of the relay device 300 indicated by the relay device ID. Therefore, in this case, if there are three pieces of information, the operation execution information, the detection device ID, and the medical worker ID, it is possible to uniquely identify the medical worker who operated the disinfection bottle 10. That is, it is possible to determine that the disinfectant bottle 10 to which the discharge operation detection device 100 indicated by the detection device ID has been operated is operated by the medical worker indicated by the medical worker ID.

On the other hand, the medical staff received with the same relay device ID within a predetermined minute time from the time of the operation of the operation execution information received with a certain relay device ID and the operation of the disinfection bottle 10 detected based on the detection device ID. When there are a plurality of person IDs, it corresponds to a situation where there are a plurality of medical workers in the vicinity of the relay device 300 indicated by the relay device ID. Therefore, in this case, the medical worker who operated the disinfecting bottle 10 cannot be uniquely identified only by the three pieces of information of the operation execution information, the detection device ID, and the medical worker ID.

In this case, the management device 400 receives the operation execution information, the detection device ID, the medical worker ID, the relative position information of the discharge operation detection device 100, and the radio received from the relay device 300 together with the same relay device ID within a predetermined minute time. Based on the relative position information of the transmitter 200, the medical worker who operated the disinfectant bottle 10 is specified. That is, the management device 400 uses each of the relative position information of the wireless transmission device 200 transmitted together with the plurality of medical worker IDs and the relative position information of the discharge operation detection device 100 transmitted together with the detection device ID. Identify the nearest healthcare professional from the disinfectant bottle 10. Then, the management device 400 identifies the medical worker closest to the disinfecting bottle 10 as the medical worker who operated the disinfecting bottle 10.

FIG. 2 is a block diagram showing a functional configuration example of the management device 400. As shown in FIG. 2, the management device 400 includes a reception information storage unit 401 and a hand hygiene management information storage unit 402 as storage media. Further, the management device 400 includes a communication unit 41, an execution number measurement unit 42, and an information recording unit 43 as functional configurations.

Each of the above functional blocks 41 to 43 can be configured by any of hardware, DSP (Digital Signal Processor), and software. For example, when configured by software, each of the above functional blocks 41 to 43 is actually configured to include a CPU, RAM, ROM, etc. of a computer, and is realized by operating a program stored in the RAM or ROM. The program may be stored in another recording medium such as a hard disk or a semiconductor memory.

The communication unit 41 receives the information transmitted from the relay device 300. Specifically, the communication unit 41 adds the operation execution information and the detection device ID transmitted from the discharge operation detection device 100 when the discharge operation detection device 100 of the disinfection bottle 10 detects the discharge operation, and the relay device 300. The relay device ID and the relative position information of the discharge operation detection device 100 are received. Further, the communication unit 41 periodically transmits the medical worker ID transmitted from the wireless transmission device 200 of the medical worker, the relay device ID added by the relay device 300, and the relative position information of the wireless transmission device 200. Receive.

Each time the communication unit 41 receives information from the relay device 300, the communication unit 41 stores the received information in the reception information storage unit 401 in chronological order. FIG. 3 is a diagram showing an example of received information stored in the received information storage unit 401. The reception information storage unit 401 stores one reception information in one record. One record includes a record ID, a reception time, a relay device ID, an operation execution information, a detection device ID, a medical worker ID, a relative position information of the discharge operation detection device 100, and a relative position information of the wireless transmission device 200 as items. include.

Note that FIG. 3 shows only the information transmitted from the relay device 300 (relay device ID = M001) in the hospital room R1 for the sake of simplicity. Further, since the wireless transmission device 200 transmits the medical worker ID every 200 milliseconds, the communication unit 41 actually receives the information every 200 milliseconds, and the record for recording the received information stores the received information. It is added to the unit 401 every 200 milliseconds, but here, the received information every 1 second is shown for simplification.

When the communication unit 41 receives information about the discharge operation detection device 100 from the relay device 300, one record is added to the reception information storage unit 401, and the record ID, reception time, relay device ID, and operation are added to the added record. Execution information, detection device ID, and relative position information of the discharge operation detection device 100 are recorded (record ID = R2, R24). The medical worker ID and the relative position information of the wireless transmission device 200 are not recorded in this record. As described above, the received information of the records R2 and R24 is the information transmitted from the discharge operation detection device 100 via the relay device 300 when the discharge operation is detected in the discharge operation detection device 100 of the disinfection bottle 10. be.

When the communication unit 41 receives information about the wireless transmission device 200 from the relay device 300, one record is added to the reception information storage unit 401, and the record ID, reception time, relay device ID, etc. are added to the added record. The medical worker ID and the relative position information of the wireless transmission device 200 are recorded (record ID = R1, R3 to R23, R25 to). The operation execution information, the detection device ID, and the relative position information of the discharge operation detection device 100 are not recorded in these records. As described above, the received information of these records R1, R3 to R23, R25 to is information that is periodically transmitted from the wireless transmission device 200 of the medical staff via the relay device 300.

The execution number measurement unit 42 receives the operation execution information, the detection device ID, and the medical worker received from the relay device 300 together with the same relay device ID within a predetermined minute time based on the information stored in the reception information storage unit 401. After identifying the medical worker who operated the disinfection bottle 10 based on the ID, the relative position information of the discharge operation detection device 100, and the relative position information of the wireless transmission device 200, the number of times of hand hygiene is executed for each medical worker. To measure.

For example, in the storage example of the reception information storage unit 401 shown in FIG. 3, the reception information of the records R2 and R3 is at the same time (actually, within a predetermined minute time of 200 milliseconds. Hereinafter, the same applies to the description of FIG. ) It is received from the relay device 300 having the same relay device ID, the record R2 is the information from the discharge operation detection device 100, and the record R3 is the information from the wireless transmission device 200. This is included in the record R3 when the discharge operation of the disinfection bottle 10 is detected by the discharge operation detection device 100 indicated by the detection device ID included in the record R2 and the operation execution information is transmitted to the relay device 300. It is shown that the medical worker ID is transmitted from the wireless transmission device 200 possessed by the medical worker indicated by the medical worker ID to the same relay device 300.

Here, the medical worker ID that is received at the same time as the time when the operation execution information included in the record R2 is received is only one of the record R3. Therefore, the execution count measuring unit 42 can identify the medical worker who has executed hand hygiene based on the detection device ID and the medical worker ID recorded in the records R2 and R3.

When there are a plurality of medical worker IDs received at the same time as the time when the operation execution information included in the record R2 is received (for example, as shown in FIG. 4, 2 indicating the same time as the record R2). (When different medical worker IDs are recorded in one of the records R3 and R4), the execution count measuring unit 42 performs the operation execution information, the detection device ID, the medical worker ID, and the ejection operation included in the records R2 to R4. Based on the relative position information of the detection device 100 and the relative position information of the wireless transmission device 200, the medical staff who operated the disinfection bottle 10 is specified. In particular, the execution count measuring unit 42 identifies the medical worker closest to the disinfection bottle 10 based on the relative position information of the discharge operation detection device 100 and the relative position information of the wireless transmission device 200, and is engaged in the medical treatment. The person is identified as the operator of the disinfection bottle 10.

The execution number measurement unit 42 identifies the medical worker who executed the hand hygiene by performing the same processing as described above for the records R24 and R25. Further, the execution count measuring unit 42 performs the same processing on other records (not shown) recorded after the record R25 to perform hand hygiene for each record in which the operation execution information is recorded. Identify the health care worker who performed it. Then, the execution number measurement unit 42 totals the execution number of hand hygiene for each medical worker based on the result specified as described above.

When the detection device ID of the disinfection bottle 10 recorded in the record is that of the discharge operation detection device 100 attached to the portable disinfection bottle 10, the execution count measuring unit 42 is used for disinfection. The medical worker who possesses the bottle 10 is specified as the operator of the disinfecting bottle 10. A database registered in advance by associating the detection device ID of the discharge operation detection device 100 attached to the portable disinfection bottle 10 with the medical worker ID of the medical worker who possesses the disinfection bottle 10 is stored in advance. There is. By referring to this database, the execution count measuring unit 42 determines whether or not the operation is for the portable disinfecting bottle 10, and if so, the medical staff possessing the disinfecting bottle 10. After identifying the person as the operator of the disinfection bottle 10, the number of times of performing hand hygiene is totaled.

When counting the number of times of hand hygiene execution, the execution number measurement unit 42 detects the operation of the disinfection bottle 10 by the same medical staff multiple times within a predetermined time (for example, 30 seconds). Multiple operations within an hour are regarded as one execution of hand hygiene, and the number of executions is measured. The predetermined time of 30 seconds is a time set on the assumption that the medical worker may operate the disinfectant bottle 10 in a plurality of times and use the disinfectant solution little by little. That is, there may be a medical worker who has a habit of imprinting the disinfectant liquid discharged the first time on the hand and then further imprinting the disinfectant liquid discharged the second time on the hand. Assuming such behavior of medical staff, a predetermined time is set as a time having a certain margin with respect to the estimated time from the first ejection operation to the second ejection operation. is doing.

In the example of the received information shown in FIG. 3, from the medical worker (medical worker ID = S007) specified as the operator of the disinfection bottle 10 from the recorded information of the records R2 and R3, and from the recorded information of the records R24 and R25. It is the same as the medical worker (medical worker ID = S007) specified as the operator of the disinfecting bottle 10, and the second operation of the disinfecting bottle 10 is from the first operation of the disinfecting bottle 10. It is done after 21 seconds, that is, within a predetermined time. Therefore, in this case, the execution count measuring unit 42 does not count the number of executions once, assuming that the medical worker with the medical worker ID included in the records R3 and R25 has executed the hand hygiene twice. The number of hand hygiene executions is counted as an execution.

That is, the example of the received information shown in FIG. 3 means that the same medical worker operated the same disinfecting bottle 10 twice within a predetermined time, but this means that the medical staff intentionally performed a plurality of operations. It is highly probable that the nozzle head of the disinfectant bottle 10 was pushed little by little in batches. Therefore, in this case, the execution count measuring unit 42 uses the information of two operation executions for the same disinfection bottle 10 by the same medical worker recorded as information within a predetermined time in the reception information storage unit 401 for hand hygiene. The number of executions is measured by regarding it as one execution.

In addition, when the amount of disinfectant discharged is small because the push operation of the nozzle head of the disinfectant bottle 10 is unintentionally insufficient, or because the remaining amount of disinfectant is small, the amount of operation of the nozzle head is sufficient. Even so, the amount of disinfectant discharged may be small. In such a case, the medical staff may operate the disinfecting bottle 10 a plurality of times in succession. Even in such a case, the execution count measuring unit 42 hand hygiene the operation execution information for the same disinfection bottle 10 by the same medical worker recorded as information within a predetermined time in the reception information storage unit 401. It is possible to measure the number of executions by regarding it as one execution of.

On the other hand, when the operation of the disinfection bottle 10 by the same medical worker is detected twice over a predetermined time, the execution number measuring unit 42 performs the same medical work twice over the predetermined time. The number of times the hand hygiene is performed by the medical staff is measured by regarding it as two executions of the hand hygiene by the person. Here, when the operation of the disinfection bottle 10 by the same medical worker twice indicated by the information recorded in the two records is linked to the same relay device ID, the execution count measuring unit 42 thereby causes the operation. The two executions of the specified hand hygiene are as the execution of hand hygiene at the time of entry and the execution of hand hygiene at the time of leaving the same medical staff in the hospital room where the relay device 300 indicated by the relay device ID is installed. , The number of times the health care worker performs hand hygiene may be measured.

The information recording unit 43 stores the medical worker specified as the performer of hand hygiene by the execution number measurement unit 42 in the hand hygiene management information storage unit 402 as history information together with information on the execution time and execution place. At this time, the information recording unit 43 uses the reception time as the execution time of hand hygiene in the record in which the detection device ID of the discharge operation detection device 100 in which the discharge operation is detected is recorded, and also uses the relay device ID as the relay device ID. The installation location of the corresponding relay device 300 is used as the execution location for hand hygiene.

Further, the information recording unit 43 stores in the hand hygiene management information storage unit 402 the number of executions of hand hygiene measured for each medical worker by the execution number measurement unit 42. Here, the information recording unit 43 may store the number of times of performing hand hygiene when entering the hospital room and the number of times of performing hand hygiene when leaving the hospital room separately.

As described in detail above, in the present embodiment, the operation execution information, the detection device ID, the medical worker ID, the relative position information of the discharge operation detection device 100, and the radio received together with the same relay device ID within a predetermined minute time. After identifying the medical staff who operated the disinfecting bottle 10 based on the relative position information of the transmission device 200, the number of times of hand hygiene is measured for each medical staff. Then, when the operation of the disinfecting bottle 10 by the same medical staff is detected multiple times within a predetermined time during the measurement of the number of executions, the multiple operations within the predetermined time are performed once for hand hygiene. The number of executions is measured by regarding it as the execution of.

According to the present embodiment configured in this way, even if the operation of the disinfection bottle 10 by the same medical worker is detected multiple times, the multiple operations are performed within a predetermined time. Is highly probable that one medical worker has performed the ejection operation in a plurality of times in one hand hygiene, and the number of times the hand hygiene is performed is measured. Thereby, according to the present embodiment, it is possible to more accurately grasp the number of times the hand hygiene is performed by the medical staff.

In the above embodiment, an example in which the execution count measuring unit 42 measures the number of executions of hand hygiene by a medical worker has been described, but in addition to this, the non-execution number of hand hygiene may be measured. .. By measuring the number of executions of hand hygiene and the number of non-executions and storing the result in the hand hygiene management information storage unit 402, it is possible to grasp the compliance rate of the execution of hand hygiene for each medical worker. The number of non-execution of hand hygiene can be measured, for example, as follows.

That is, it is possible to identify the flow line of the medical worker by tracing the transition of the relay device ID recorded together with the medical worker ID based on the received information stored in the received information storage unit 401. .. That is, the medical worker entered the hospital room R1, R2, R3 from the information of the record in which the medical worker ID is recorded together with the relay device ID of the relay device 300 installed in the hospital rooms R1, R2, R3. Can be identified. It is also possible to identify that the medical staff has left the hospital rooms R1, R2, and R3 (moved to another place due to a change in the relay device ID). When the operation of the disinfectant bottle 10 is not detected between entering and leaving the room for one hospital room (when there is no record in which the detection device ID is recorded), or when the operation of the disinfectant bottle 10 is detected. However, if it is detected that the operation is performed by another medical worker, it can be determined that the hand hygiene by the medical worker has not been performed. The execution number measurement unit 42 can total the number of non-execution of hand hygiene determined in this way.
