[Composition of medical equipment]
FIG. 2 is a block diagram for explaining the configuration of the medical medical care apparatus 10 according to the present embodiment. As shown in FIGS. 1 and 2, the medical care apparatus 10 includes a medical care chair 1, a foot controller 5, a tray table 3, a control device 9, an instrument holder 50, an operation panel 8, and a display monitor 6. And a basin unit 2 and a lighting device (for example, a dental light) 7.

The medical chair 1 includes a headrest 1a that supports the patient's head, a backrest 1b that supports the patient's back, a seat seat 1c that supports the patient's tail, a footrest 1d that supports the patient's feet, and a seat drive unit 11. To prepare for. Each of the headrest 1a, the backrest 1b, the seat surface seat 1c, and the footrest 1d is driven under the control of the seat drive unit 11.

For example, each of the headrest 1a, the backrest 1b, and the footrest 1d moves in the vertical direction or the horizontal direction with respect to the seat surface seat 1c under the control of the seat driving unit 11. When the headrest 1a, the backrest 1b, and the footrest 1d are positioned perpendicular to the seat 1c, the patient sitting on the medical chair 1 is in the sitting position. When the headrest 1a, the backrest 1b, and the footrest 1d are positioned horizontally with respect to the seat 1c, the patient sitting on the medical chair 1 is in a supine position.

The foot controller 5 has a plurality of switches (pedals) that accept a user's foot operation. The user can assign a predetermined function to each of these plurality of switches.

For example, the user can assign a function of changing the posture of the medical chair 1 to the switch of the foot controller 5. When the user steps on the switch to which the function of changing the posture of the medical chair 1 is assigned, the foot controller 5 outputs a control signal to the seat drive unit 11. The seat drive unit 11 drives the headrest 1a and the like based on the control signal.

Further, the user can assign the function of driving the medical device 4 to the switch of the foot controller 5. When the user steps on the switch to which the function of driving the medical device 4 is assigned, the foot controller 5 outputs a control signal to the medical device driving unit 14 described later. The medical instrument driving unit 14 controls the driving of the medical instrument 4 based on the control signal.

It should be noted that other functions such as a function of controlling lighting and extinguishing of the lighting device 7 can be assigned to the switch of the foot controller 5.

The tray table 3 is used as a storage table for medical treatment. The tray table 3 is connected to a medical chair 1 or an arm extending from the floor (not shown).

The medical instrument 4 is not limited to these, and may be an intraoral camera, a photopolymerization irradiator, a root canal length measuring device, a three-dimensional scanner, a root canal magnifying device, or the like, a dental mirror, a syringe, or the like. And it may be a non-driving device such as a filling device.

In the medical treatment device 10, five types of medical treatment instruments 4a to 4e are used. For example, the medical instrument 4a and the medical instrument 4b are air turbine handpieces. The medical instrument 4c is a micromotor handpiece. The medical instrument 4d is a scaler. The medical instrument 4e is a three-way syringe.

Each medical instrument 4 is held by an instrument holder 50. When the medical instrument 4 is taken out from the instrument holder 50, the holding by the instrument holder 50 is released, and the medical instrument 4 is in the selected state (selected state).

Each medical instrument 4 is connected to a medical instrument driving unit 14 included in the control device 9. The medical device driving unit 14 drives each medical device 4 based on the user's stepping operation on the foot controller 5. For example, when the user steps on the switch for driving the air turbine handpiece in the foot controller 5, the medical instrument drive unit 14 rotates the cutting tool held by the head portion of the air turbine handpiece. In this way, the medical device driving unit 14 drives the medical device 4 based on the user's operation with respect to the foot controller 5.

The instrument holder 50 is a holding member that holds each medical instrument 4. The instrument holder 50 is connected to the operation control unit 12 via the holding / release specific unit 19 included in the control device 9. The holding release specifying unit 19 specifies that the holding of the medical instrument 4 by the instrument holder 50 has been released, and outputs a signal indicating the specific result to the operation control unit 12.

As shown in FIG. 1, the basin unit 2 is provided on the side of the medical chair 1. The baseon unit 2 includes a pot 2a on which a drainage port is formed, a cup stand 2b on which a cup 70 is placed, and a water tap 2c for supplying water to the cup 70. As shown in FIG. 2, the basin unit 2 includes a basin control unit 16. The basin control unit 16 controls the flow of water used in the medical device 10. The cup 70 corresponds to one embodiment of the "storage container".

Here, the main configuration of the baseon unit 2 will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram for explaining the configuration included in the baseon unit 2 according to the present embodiment. As shown in FIG. 3, the water tap 2c includes a strut portion 21c and a extending portion 22c extending horizontally from the upper part of the strut portion 21c. A water supply port 102 for supplying liquid to the cup 70 is provided on the surface of the extending portion 22c facing the cup 70. In this embodiment, water is exemplified as a liquid. Further, the water tap 2c is provided with a cup detection sensor 101 and a full water detection sensor 103.

The cup detection sensor 101 detects whether or not the cup 70 is placed on the cup table 2b by detecting the presence or absence of blocking of infrared rays. Specifically, a light emitting portion 101a that emits infrared rays is provided at the lower part of the support column portion 21c so as to be directed diagonally upward where the cup 70 is located. On the other hand, the extending portion 22c is provided with a light receiving portion 101b at a position facing the light emitting portion 101a. When the cup 70 is not placed on the cup table 2b, the infrared rays emitted from the light emitting unit 101a reach the light receiving unit 101b, and the infrared rays are detected by the light receiving unit 101b. On the other hand, when the cup 70 is placed on the cup table 2b, the infrared rays emitted from the light emitting unit 101a are blocked by the cup 70 and do not reach the light receiving unit 101b, so that the infrared rays are not detected by the light receiving unit 101b. The cup detection sensor 101 is turned off when infrared rays are detected by the light receiving unit 101b, while it is turned on when infrared rays are not detected by the light receiving unit 101b.

The cup detection sensor 101 is not limited to a sensor that detects light such as infrared rays. For example, the cup detection sensor 101 analyzes a weight sensor that detects the cup 70 by detecting a change in the weight applied to the cup table 2b, a magnetic sensor that detects the cup 70 by detecting a change in the magnetic field, or an image taken. By doing so, various sensors using known techniques such as a camera sensor that detects the cup 70 can be applied.

The full water detection sensor 103 includes electrodes 103a and 103b provided at the tip of the water supply port 102, and detects a change in the circuit resistance of the water column formed through the water stored in the cup 70, thereby making the cup 70. Detects that more than a predetermined amount of water has been stored. In the present embodiment, the full water detection sensor 103 detects that the cup 70 is full. Specifically, when the cup 70 is empty, the resistance value detected by the full water detection sensor 103 is infinite, and the resistance value decreases as the water level of the cup 70 rises. When the cup 70 is full, the resistance value detected by the electrodes 103a and 103b becomes equal to or less than the reference resistance value. The full water detection sensor 103 is turned off when the resistance value detected by the electrodes 103a and 103b is larger than the reference resistance value, while the resistance value detected by the light receiving unit 101b by the electrodes 103a and 103b is smaller than the reference resistance value. Sometimes it goes on. The principle of detecting full water in the cup 70 by changing the circuit resistance of the water column is described in Japanese Patent No. 3496258 and the like.

The full water detection sensor 103 is not limited to a sensor that detects a change in the circuit resistance of the water column. For example, the full water detection sensor 103 is a known technique such as a weight sensor that detects full water by detecting a change in weight applied to the cup table 2b, or an ultrasonic sensor that detects full water by detecting a change in ultrasonic waves. Various sensors using the above can be applied.

FIG. 4 is a schematic diagram for explaining the configuration of the baseon control unit 16 according to the present embodiment. As shown in FIG. 4, the basin control unit 16 includes an on-off valve 113, a motor 114, a cup detection sensor 101, a full water detection sensor 103, and a basin control board 120. The motor 114 is an embodiment of the "supply unit".

The on-off valve 113 is connected to the motor 114 and changes the opening degree according to the drive of the motor 114 to supply water from the water supply source to the water supply port. The water supply source is, for example, tap water or a water storage tank.

A CPU (Central Processing Unit) 121, a ROM (Read Only Memory) 122, a RAM (Random Access Memory) 123, and the like are mounted on the baseon control board 120. The basin control board 120 and the CPU 121 are an embodiment of the "control unit".

A motor 114 is connected to the CPU 121. The CPU 121 drives the motor 114 by applying a constant voltage with a drive signal. The motor 114 is turned on when the on-off valve 113 is started to open and close under the control of the CPU 121, while it is turned off when the on-off valve 113 is finished on and off. For example, when the on-off valve 113 is opened, the motor 114 opens the valve by turning it on in a mode corresponding to the opening. Then, when the opening of the on-off valve 113 reaches the limit, the motor 114 switches from the ON state to the OFF state. On the other hand, when the on-off valve 113 is closed, the motor 114 closes the valve by turning it on in a mode corresponding to the closing. Then, when the closing of the on-off valve 113 reaches the limit, the motor 114 switches from the ON state to the OFF state.

A cup detection sensor 101 is connected to the CPU 121. The cup detection sensor 101 outputs an ON signal to the CPU 121 when the cup 70 is detected and is in the ON state. On the other hand, the cup detection sensor 101 does not output an ON signal to the CPU 121 when the cup 70 is not detected and is in the OFF state. Further, a full water detection sensor 103 is connected to the CPU 121. The full water detection sensor 103 outputs an ON signal to the CPU 121 when it is in the ON state when full water is detected. On the other hand, the full water detection sensor 103 does not output an ON signal to the CPU 121 when it is in the OFF state in which full water is not detected.

When the CPU 121 starts receiving the ON signal from the cup detection sensor 101, the CPU 121 starts outputting the drive signal to the motor 114. As a result, when the cup 70 is placed on the cup stand 2b, the on-off valve 113 opens and the water supply to the water supply port 102 starts. When the CPU 121 starts receiving the ON signal from the full water detection sensor 103, the CPU 121 ends the output of the drive signal to the motor 114. As a result, when the cup 70 is full, the on-off valve 113 closes, and the supply of water to the water supply port 102 ends. When the cup 70 is removed from the cup table 2b, the transmission of the ON signal from the cup detection sensor 101 to the CPU 121 ends, and the transmission of the ON signal from the full water detection sensor 103 to the CPU 121 ends.

Returning to FIG. 2, the basin unit 2 further includes a lighting control unit 17. The lighting control unit 17 controls lighting and extinguishing of the lighting device 7. The lighting control unit 17 is composed of a CPU, a ROM, a RAM, and the like mounted on a lighting control board (not shown).

Further, the baseon unit 2 includes a history collecting unit 18 for collecting history information in the medical device 10. The history collection unit 18 is composed of a CPU, a ROM, a RAM, and the like mounted on a history collection board (not shown), and is provided inside the maintenance door 2d of the baseon unit 2. Therefore, the memory 18b such as the ROM or RAM cannot be removed from the history collection board unless the maintenance door 2d is opened using a predetermined tool. The history collection unit 18 is an embodiment of the “collection unit”. Further, the memory 18b is an embodiment of the "storage unit".

The history collection board is provided with an output port 18a for outputting history information to the analysis PC 20. The maintenance worker can take out the collected history information by opening the maintenance door 2d and connecting the wiring from the analysis PC 20 to the output port 18a. Of course, the analysis PC 20 and the history collection unit 18 of the medical device 10 may always be connected to each other via the output port 18a.

The history information collected by the history collection unit 18 is stored in a memory 18b that can be attached to and detached from the history collection board. The memory 18b is a storage medium composed of a non-volatile memory such as a memory card. The maintenance worker can open the maintenance door 2d and remove the memory 18b from the history collection board. Therefore, the maintenance worker can acquire the collected history information simply by removing the memory 18b from the history collection board and connecting it to the analysis PC 20 without connecting the wiring from the analysis PC 20 to the output port 18a. Can be done. The history collection board may not be provided with the output port 18a. When the history collection board is not provided with the output port 18a, the analysis PC 20 directly accesses the memory 18b and acquires the history information from the medical device 10.

Related known techniques such as CAN (Controller Area Network) communication are applied to the communication between the control boards in the medical device 10. In the medical device 10, all control boards such as a chair control board, an operation control board, a drive control board, a monitor control board, a holding release specific control board, a baseon control board 120, and a lighting control board communicate with each other by CAN communication. , Sharing each other's situation and controlling. In CAN communication, communication data including information related to control in each control board is converted into a communication packet, and communication is performed between the control boards. In communication between control boards, if communication data including information related to control on each control board is transmitted and received, it is not necessary to make a communication packet. Here, the information related to control includes information such as switches, sensors, actuators, and statuses controlled by each control board.

By connecting the history collection board so that CAN communication can be performed with another control board, the history collection unit 18 can collect information related to control on each control board as history information. The history collection unit 18 sends, for example, information on chair unit position control sent from the chair control board, information on the medical instrument 4 sent from the operation control unit 12, and information from the baseon control unit 16 via CAN communication. Information on controlling the supply of water to the incoming cup 70 (for example, information on the drive time of the motor 114 (hereinafter, also referred to as drive time information)), lighting control of the lighting device 7 sent from the lighting control unit 17. Information related to various controls is collected as history information from communication packets including information such as. The history information collected by the history collecting unit 18 includes at least the operation history of the operation performed by the medical treatment device 10 and the detection history detected by the medical treatment device 10.

The sensor E is, for example, a full water detection sensor 103.

In the communication packet of the communication packet ID "4", the information of the switch A controlled by the operation control unit 12 is set to "DATA1", the information of the switch B is set to "DATA2", and the information of the switch C is set to "DATA3". The information of the switch D is assigned to "DATA4" respectively.

Each control board carries information such as switches, sensors, actuators, and status on the communication packet shown in FIG. 6 and transmits it to other control boards so that all the control boards operate in cooperation with each other. Is possible. Therefore, by connecting the history collection board to the wiring capable of receiving communication packets, the history collection unit 18 can collect information on control in each control board from a plurality of control boards as history information. Become.

FIG. 7 is a diagram for explaining the history information collected by the history collection unit 18. Note that FIG. 7 shows an example of historical information regarding control of water supply to the cup 70 in the basin unit 2 (hereinafter, also referred to as water supply control).

In the communication packet communicated between the control boards, information is identified by attaching an event code according to the format shown in FIG. For example, when the information of the sensor D (“DATA1”) of the basin control board 120 (communication packet ID “3”) is included in the communication packet, the history collection unit 18 is the information for identifying the basin control board 120. The event code "31001" corresponding to the communication packet ID "3" and the information identifying the sensor D is generated and stored in the history information. Therefore, since the event code corresponding to the communication packet ID and the information for identifying the actuator, the sensor, etc. is always stored in the history information collected by the history collection unit 18, which control board, which, the actuator, the sensor, etc. It is possible to identify whether it is information. "31002" and "320002" are assigned as event codes to the information of the actuator E ("DATA2") of the baseon control board 120 (communication packet ID "3"). Of these, "31002" is assigned as the event code when the motor 114 corresponding to the actuator E opens the on-off valve 113, and "320002" is assigned as the event code when the motor 114 closes the on-off valve 113. ing. "31003" is assigned as an event code to the information of the sensor E ("DATA3").

Further, the history collecting unit 18 generates an event parameter corresponding to the data included in the communication packet and stores it in the history information. For example, when the event parameter of the event code "31001" is "1", the CPU 121 of the baseon control board 120 (communication packet ID "3") is receiving an ON signal from the sensor D (cup detection sensor 101: "DATA1"). The communication packet contains information indicating that the signal is. On the other hand, when the event parameter of the event code "31002" is "0", the communication packet includes information indicating that the CPU 121 is not receiving the ON signal from the sensor D.

For example, when the event parameter of the event code "31002" is "1", the CPU 121 of the baseon control board 120 (communication packet ID "3") causes the actuator E (motor 114: "DATA2") to open the on-off valve 113. The communication packet contains information indicating that the drive signal of is being transmitted. On the other hand, when the event parameter of the event code "31002" is "0", the communication packet includes information indicating that the CPU 121 is not transmitting the drive signal for opening the on-off valve 113 to the actuator E.

For example, when the event parameter of the event code "320002" is "1", the CPU 121 of the baseon control board 120 (communication packet ID "3") causes the actuator E (motor 114: "DATA2") to close the on-off valve 113. The communication packet contains information indicating that the drive signal of is being transmitted. On the other hand, when the event parameter of the event code "320002" is "0", the communication packet includes information indicating that the CPU 121 is not transmitting a drive signal for closing the on-off valve 113 to the actuator E.

For example, when the event parameter of the event code "31003" is "1", the CPU 121 of the baseon control board 120 (communication packet ID "3") is receiving an ON signal from the sensor E (full water detection sensor 103: "DATA3"). The communication packet contains information indicating that the signal is. On the other hand, when the event parameter of the event code "31003" is "0", the communication packet includes information indicating that the CPU 121 is not receiving the ON signal from the sensor E.

The history information collected by the history collection unit 18 stores date and time information as well as event codes and event parameters. As will be described later, the history collection unit 18 does not store all communication packets, but when there is a change in the time difference between the communication packet ID and the data included in the communication packet (when an event occurs). , Event code and event parameters are generated and stored in the history information.

In CAN communication, information is carried on a communication packet and transmitted to another control board even if the target controlled by the control board does not change. For example, even if the fact that the CPU 121 is receiving the ON signal from the cup detection sensor 101 does not change from the time of the previous transmission, the information corresponding to the same event code and event parameter as the previous time is put on the communication packet and controlled. It is sent to the board. Therefore, if the history collection unit 18 collects all the information of the transmitted communication packet and stores it in the memory 18b, the amount of information to be stored becomes enormous, and the capacity that can be stored in the memory 18b is exceeded in a short time. Will end up. Therefore, the history collecting unit 18 according to the present embodiment collects history information from the communication packet only when there is a change in the target controlled by the control board (when an event occurs).

Here, FIG. 8 is a timing chart showing the presence / absence of sensor detection and the timing of motor drive in the water supply of the cup 70. In FIG. 8, a line indicating the timing when the cup detection sensor 101 is turned on, a line indicating the timing when the full water detection sensor 103 is turned on, and a line indicating the timing when the motor 114 is driven are on the time axis.

When the driving of the motor 114 starts, the water supply to the cup 70 starts. When the opening of the on-off valve 113 reaches the limit at time t3, the driving of the motor 114 is terminated and the motor 114 is turned off. When the fullness of the cup 70 is detected by the fullness detection sensor 103 at time t4, the fullness detection sensor 103 is turned on. Then, at time t5, the driving of the motor 114 for closing the on-off valve 113 starts, and the motor 114 is turned on.

When the closing of the on-off valve 113 reaches the limit at time t6, the driving of the motor 114 is terminated and the motor 114 is turned off. As a result, the water supply to the cup 70 is completed. After that, at time t7, when the detection of the cup 70 is completed by the cup detection sensor 101, the cup detection sensor 101 is turned off. Then, at time t8, the full water detection sensor 103 does not detect the full water of the cup 70, and the full water detection sensor 103 is turned off.

When the cup detection sensor 101, the full water detection sensor 103, and the motor 114 operate according to a series of flows as shown in FIG. 8, the history collection unit 18 collects history information as follows.

As shown in FIG. 8, the cup detection sensor 101 changes from the OFF state to the ON state at time t1. In this case, as shown in FIG. 7, the history collection unit 18 uses the information of the event code “31001” and the event parameter “1” as the history information at the time (t1) of the date (2017/5/25) in the memory 18b.

As shown in FIG. 8, the motor 114 is changed from the OFF state to the ON state in order to open the on-off valve 113 at time t2. In this case, as shown in FIG. 7, the history collection unit 18 uses the information of the event code “31002” and the event parameter “0” at the time (t2) of the date (2017/5/25) as the history information in the memory 18b. Remember in.

As shown in FIG. 8, the motor 114 has changed from the ON state to the OFF state again at time t3. In this case, as shown in FIG. 7, the history collection unit 18 uses the information of the event code “31002” and the event parameter “1” as the history information at the time (t3) of the date (2017/5/25) in the memory 18b. Remember in.

As shown in FIG. 8, the full water detection sensor 103 changes from the OFF state to the ON state at time t4. In this case, as shown in FIG. 7, the history collection unit 18 uses the information of the event code “31003” and the event parameter “1” at the time (t4) of the date (2017/5/25) as the history information in the memory 18b. Remember in.

As shown in FIG. 8, the motor 114 is changed from the OFF state to the ON state in order to close the on-off valve 113 at time t5. In this case, as shown in FIG. 7, the history collection unit 18 uses the information of the event code “320002” and the event parameter “1” at the time (t5) of the date (2017/5/25) as the history information in the memory 18b. Remember in.

As shown in FIG. 8, the motor 114 has changed from the OFF state to the ON state again at time t6. In this case, as shown in FIG. 7, the history collection unit 18 uses the information of the event code “320002” and the event parameter “0” at the time (t6) of the date (2017/5/25) as the history information in the memory 18b. Remember in.

As shown in FIG. 8, the cup detection sensor 101 changes from the ON state to the OFF state at time t7. In this case, as shown in FIG. 7, the history collection unit 18 uses the information of the event code “31001” and the event parameter “0” at the time (t7) of the date (2017/5/25) as the history information in the memory 18b. Remember in.

As shown in FIG. 8, the full water detection sensor 103 changes from the ON state to the OFF state at time t8. In this case, as shown in FIG. 7, the history collection unit 18 uses the information of the event code “31003” and the event parameter “0” at the time (t8) of the date (2017/5/25) as the history information in the memory 18b. Remember in.

As described above, the medical device 10 according to the present embodiment modifies the existing board and system configuration in order to collect the history information of various controls from the communication packets communicated between the plurality of control boards. It is possible to collect history information without any. In particular, the history collection board only receives and monitors communication packets, and does not affect the control of the entire medical device 10. That is, since the algorithm for collecting history information does not affect the system of the medical device 10, it is necessary to construct a mechanism for easily collecting history information without modifying the existing board or system configuration. Can be done.

Further, the history collecting unit 18 collects information changed from the previously stored history information from the communication packet and stores it in the memory 18b as the history information. Therefore, the amount of history information stored in the memory 18b can be reduced as compared with the case where all the information related to the control in each control board is stored, and it is not necessary to prepare the memory 18b having a large capacity. Further, even when the analysis computer 20 is connected to the output port 18a of the history collection board and the history information stored in the memory 18b is taken out, the amount of the history information stored in the memory 18b is suppressed, so that the analysis computer 20 is used. Can retrieve the history information stored in the memory 18b in a short time.

Of course, if there is no limitation on the amount of information, the history collection unit 18 stores all the information included in the communication packet even if the target controlled by the control board does not change (when no event occurs). You may.

[Overview of anomaly detection]
As described above, in the medical device 10 according to the present embodiment, information on control in each control board is shared between the control boards by communication packets, and the information is collected by the history collection unit 18 as history information. It is configured to be. In the medical care system 1000 according to the present embodiment, such an existing board and system configuration are used as they are, and the analysis PC 20 detects an abnormality in the medical care device 10 based on the history information acquired by the history collection unit 18. do. Hereinafter, in the medical care system 1000 according to the present embodiment, a process for determining an abnormality of the medical care device will be described.

FIG. 9 is a block diagram for explaining a function related to abnormality detection of the medical care system 1000 according to the present embodiment. As shown in FIG. 9, the medical device 10 outputs the history collecting unit 18 for collecting history information, the memory 18b for storing the collected history information, and the history information stored in the memory 18b to the analysis PC 20. The output port 18a of the above is provided. In the medical device 10 shown in FIG. 2, the output port 18a is shown in the frame of the history collection unit 18 in order to show that the output port 18a is mounted on the history collection board constituting the history collection unit 18. However, in the medical device 10 shown in FIG. 9, the history collecting unit 18 and the output port 18a are shown separately in order to explain each process.

The analysis PC 20 includes a determination unit 21, a comparison unit 23, an update unit 24, a storage unit 25, and an interface unit 206. The comparison unit 23 compares the history information collected by the history collection unit 18 with the reference information. The comparison unit 23 may use the history information itself to compare with the reference information, or may compare the history information with the reference information after converting it by calculation or the like. The storage unit 25 stores the reference information used in the comparison unit 23, the determination result obtained by the determination unit 21, and the like. The determination unit 21 determines whether or not there is an abnormality in the medical device 10 based on the comparison result obtained by the comparison unit 23. The determination unit 21 can determine and predict a failure in the medical device 10 by determining the presence or absence of an abnormality in the medical device 10. The update unit 24 updates the reference information used in the comparison unit 23 to an appropriate value based on the comparison result obtained by the comparison unit 23. The analysis computer 20 is a detection device that is communicably connected to the medical device 10 and detects an abnormality in the medical device 10, and may include at least one of a comparison unit 23 and a determination unit 21. .. Further, the analysis computer 20 does not have to include the update unit 24. In this case, predetermined fixed reference information such as design values is used for abnormality detection.

[Abnormality detection related to Basin unit]
In the medical care system 1000 according to the present embodiment, an abnormality of the medical care apparatus 10, particularly, using information on water supply control in the baseon unit 2 (for example, drive time information of the motor 114) sent from the baseon control board 120. Detects abnormalities related to water supply control.

FIG. 10 is a flowchart for explaining an abnormality detection process executed by the medical care system 1000 according to the present embodiment. The abnormality detection process shown in FIG. 10 is performed in a state where the analysis PC 20 is connected to the output port 18a of the history collection unit 18 included in the medical device 10. The abnormality detection process may be executed when the analysis PC 20 is connected to the output port 18a, or an instruction is given by the user via the input unit 208 with the analysis PC 20 connected to the output port 18a. It may be executed when it is received. Further, the abnormality detection process is executed at predetermined intervals (for example, every time a series of operations from the start of water supply to the fullness of water is completed) with the analysis PC 20 connected to the output port 18a. It may be done, or it may be executed all the time (for example, every sampling time). Further, the user or the maintenance worker may be able to arbitrarily set the execution timing of the abnormality detection process.

As shown in FIG. 10, the medical care apparatus 10 outputs the drive time information of the motor 114 stored in the memory 18b as history information to the analysis PC 20 (S11). Specifically, in the medical device 10, the event parameter of the event code "31002" corresponding to the actuator E (motor 114) is changed from "0" (motor 114 is in the OFF state) to "1" (motor 114 is in the ON state). The time information at the time of change (time t2 in the example shown in FIG. 7) and then the event parameter of the event code "320002" corresponding to the actuator E (motor 114) changes from "1" (motor 114 is ON) to ". The time information (time t6 in the example shown in FIG. 7) when the motor 114 changes to 0 ”(the motor 114 is in the OFF state) is output to the analysis PC 20. That is, the drive time information includes the time when the on-off valve 113 starts to open (t2) and the time when the on-off valve 113 closes is completed (t6).

On the other hand, the analysis PC 20 acquires the drive time information of the motor 114 as history information from the memory 18b via the interface unit 206 (S21). Next, the analysis PC 20 calculates the water pressure from the drive time information of the motor 114 included in the acquired history information by the comparison unit 23 (S22). For example, the analysis PC 20 calculates the drive time of the motor 114 based on the time t2 when the on-off valve 113 starts to open and the time t6 when the on-off valve 113 closes is completed. Then, the analysis PC 20 calculates the current water pressure (hereinafter, also referred to as actual water pressure) based on the amount of water stored in the cup 70 when the water is full and the driving time of the motor. The amount of water at the time of full water may be stored in the medical device 10 and transmitted to the analysis PC 20 together with the history information, or may be stored in advance by the analysis PC 20. As another calculation method, the analysis PC 20 may divide the driving time of the motor 114 by the result of multiplying the reference water pressure by the time until the reference water becomes full. The reference water pressure and the reference time until the water is full may be stored in the medical device 10 and transmitted to the analysis PC 20 together with the history information, or may be stored in advance by the analysis PC 20.

The analysis PC 20 compares the water pressure (actual water pressure) calculated by the comparison unit 23 with the reference water pressure (hereinafter, also referred to as the reference water pressure) (S23).

In the process of S23, the analysis PC 20 compares the actual water pressure with the reference water pressure and calculates the difference. Then, the analysis PC 20 compares the difference with the threshold value stored in the storage unit 25 in advance. In this example, the drive time information of the motor 114 corresponds to one embodiment of "correspondence information", and the reference water pressure and the threshold value correspond to one embodiment of "reference information".

The analysis PC 20 detects an abnormality in the medical device 10, particularly an abnormality related to water supply control, by the determination unit 21 (S24). When it is determined that the difference between the actual water pressure and the reference water pressure is larger than the threshold value based on the comparison result obtained by the treatment of S23 (YES in S24), the analysis PC 20 differs depending on the degree of abnormality. Then, the display unit 204 notifies that an abnormality has occurred (S25). For example, different warning images are displayed on the display unit 204 according to the difference between the actual water pressure and the reference water pressure and the degree of deviation from the threshold value. For example, the larger the degree of deviation, the sooner a warning image such as prompting for repair is displayed on the display unit 204. Not limited to the display unit 204, an abnormality may be notified by using a speaker, a lamp, or the like (not shown).

When the analysis PC 20 determines that the difference between the actual water pressure and the reference water pressure is smaller than the threshold value (NO in S24), the updating unit 24 updates the reference water pressure based on the actual water pressure (S26). Specifically, the analysis PC 20 calculates the average value of the past water pressure based on the reference water pressure used in the treatment of S23 and the actual water pressure calculated in the treatment of S22. Then, the analysis PC 20 stores the calculated average value in the storage unit 25 as a new reference water pressure. From the next time, the analysis PC 20 will execute the abnormality detection process using this new reference water pressure. The analysis PC 20 ends the abnormality detection process after the process of S25 or after the process of S26.

The abnormality detection process shown in FIG. 10 was performed in a state where the analysis PC 20 was connected to the output port 18a of the history collection unit 18, but of course, the memory 18b was removed from the history collection board for analysis. It can be applied even in the state of being connected to the PC 20. In this case, the process of S11 executed by the medical device 10 may be replaced with the process of the memory 18b alone.

As described above, in the medical care system 1000 according to the present embodiment, the history collection unit 18 collects history information from the communication data transmitted / received on the baseon control board 120. The history information includes drive time information of the motor 114. The comparison unit 23 calculates the water pressure from the drive time information of the motor 114 collected as history information, and compares the calculated actual water pressure with the reference water pressure included in the reference information stored in advance in the storage unit 25. The determination unit 21 determines whether or not there is an abnormality in the medical device 10, particularly an abnormality related to water supply control, based on the comparison result by the comparison unit 23.

In this way, the medical care system 1000 can detect an abnormality related to water supply control based on history information of various controls collected from communication packets communicated between a plurality of control boards. If an abnormality in the water pressure is detected by the abnormality detection process, the user or the maintenance worker can use the abnormality on the water supply source side or the abnormality on the medical device 10 side (for example, the route from the water supply source to the water supply port 102). Abnormalities in the motor 114, the cup detection sensor 101, the full water detection sensor 103, the CPU 121 included in the Basin control board 120, and the like) can be suspected.

Further, since the medical care system 1000 detects an abnormality related to water supply control based on history information of various controls collected from communication packets communicated between a plurality of control boards, it detects an abnormality related to water supply control. Therefore, it is not necessary to separately provide a sensor and a configuration for processing the result detected by the sensor. As a result, the medical care system 1000 can detect an abnormality in the medical care device 10 without modifying the existing board or system configuration.

In the medical care system 1000, the history information collected by the history collection unit 18 is aggregated and stored in the memory 18b. The comparison unit 23 acquires the history information stored in the memory 18b via the interface unit 206, and compares the acquired history information with the reference information. Of course, the medical care system 1000 may acquire the history information directly from the history collection unit 18 by the comparison unit 23 without providing the memory 18b. Further, the storage unit for storing the history information may be provided by the analysis computer 20 instead of the medical device 10.

In the medical care system 1000, the renewal unit 24 updates the reference water pressure so as to be the average value of the past actual water pressure based on the actual water pressure. As a result, it is not necessary to teach the reference water pressure to the analysis PC 20 every time the abnormality detection process is executed.

In the medical care system 1000, when an abnormality related to water supply control is detected by the determination unit 21, the display unit 204 notifies that the abnormality has occurred in a different manner depending on the degree of the abnormality. This makes it easier for users and maintenance workers to recognize the degree of abnormality.

[Modification example]
The present invention is not limited to the above examples, and various modifications and applications are possible. Hereinafter, modifications applicable to the present invention will be described.

[Details of anomaly detection]
In the medical care system 1000 according to the present embodiment, the drive time information of the motor 114 is included in the history information, the actual water pressure calculated based on the drive time information of the motor 114, and the reference water pressure included in the reference information. By comparison, anomalies related to water supply control were detected. That is, in the medical care system 1000 according to the present embodiment, an abnormality related to water supply control is detected using the actual water pressure calculated based on the drive time information of the motor 114. However, not limited to this, the analysis PC 20 calculates the drive time of the motor 114 until the cup 70 is full based on the drive time information of the motor 114, and the calculated drive time and the standard stored in advance are used. By comparing with the drive time of the motor 114, an abnormality related to water supply control may be detected. The drive time of the reference motor 114 may be a predetermined drive time such as a design value, or may be an average value of drive times calculated in the past in the medical care system 1000. Further, the drive time of the reference motor 114 may be the maximum value of the drive time calculated in the past in the medical care system 1000.

In the medical care system 1000 according to the present embodiment, an abnormality related to water supply control is detected based on the driving time of the motor 114 (that is, the time from the opening of the on-off valve to the closing of the on-off valve). However, the method of detecting the fullness of the cup 70 is not limited to the driving time of the motor 114. For example, the time from the time when the cup detection sensor 101 is turned on (t1 in FIG. 8) to the time when the full water detection sensor 103 is turned on (t4 in FIG. 8) is regarded as the time when the cup 70 is full. Then, an abnormality related to water supply control may be detected based on the ON / OFF state of the cup detection sensor 101 and the full water detection sensor 103.

In the medical care system 1000 according to the present embodiment, as one embodiment of abnormality detection, an abnormality related to control of water supply to the cup 70 (water supply control) in the basin unit 2 is detected. However, not limited to the cup 70, the medical care system 1000 may detect an abnormality related to control of water supply to other storage containers.

For example, a vacuum tank may be applied as a storage container. Specifically, the vacuum tank is a storage container for storing a liquid such as saliva of a patient or water injection of a turbine sucked by a vacuum syringe. When a predetermined amount or more of the liquid is stored in the vacuum tank, the liquid is discharged from the drainage pipe. In such a vacuum tank, when the sensor detects that a predetermined amount or more of the liquid has been stored, the information to that effect is collected by the history collecting unit 18 by the communication packet, while the sensor that the liquid has been discharged is completed. Information to that effect may be collected in the history collection unit 18 by a communication packet when the sensor is detected. Then, the analysis PC 20 calculates the discharge time of the liquid in the vacuum tank based on the detection result of the sensor acquired from the history collection unit 18, and compares the calculated discharge time with the reference discharge time to make the vacuum tank or the drain pipe. The presence or absence of an abnormality on the road may be determined.

Alternatively, when water is stored in the vacuum tank from a water supply source such as tap water, when the sensor detects that the water storage has started, information to that effect is collected in the history collection unit 18 by a communication packet. On the other hand, when the sensor detects that the water storage is completed, the information to that effect may be collected in the history collecting unit 18 by the communication packet. Then, the analysis PC 20 calculates the water storage time and water pressure in the vacuum tank based on the detection result of the sensor acquired from the history collection unit 18, and compares the calculated storage time and water pressure with the reference information to provide a water supply source or the like. The presence or absence of an abnormality in the above may be determined.

As described above, as long as the storage time and the discharge time can be detected by collecting the history information from the communication data transmitted and received on the control board by the history collection unit 18, the present embodiment can be used for any storage container. The abnormality can be detected by the medical care system 1000 according to the above.

[Abnormality detection on the medical device itself]
The medical care system 1000 according to the present embodiment detects an abnormality in the medical care device 10 by an analysis computer 20 connected to the medical care device 10. However, the medical device 10 itself may detect the abnormality. FIG. 11 is a block diagram for explaining a function related to abnormality detection of the medical treatment apparatus 10a according to a modified example. The medical device 10a shown in FIG. 11 includes a history collection unit 18, a memory 18b, a determination unit 21, a comparison unit 23, an update unit 24, and a storage unit 25. The medical device 10a collects history information from the communication data transmitted / received on the baseon control board 120 by the history collection unit 18 and stores it in the memory 18b. The comparison unit 23 acquires the history information stored in the memory 18b, and compares the acquired history information with the reference information stored in the storage unit 25. The determination unit 21 determines whether or not there is an abnormality in the medical device 10a, particularly an abnormality related to water supply control in the basin unit 2, based on the comparison result by the comparison unit 23. The update unit 24 updates the reference information based on the history information. As described above, the medical device 10a detects the abnormality related to the water supply control based on the history information of various controls collected from the communication packets communicated between the plurality of control boards, so that the abnormality related to the water supply control is detected. In order to detect it, it is not necessary to separately provide a sensor and a configuration for processing the result detected by the sensor. As a result, the medical care system 10a can detect an abnormality in the medical care device 10a without modifying the existing board or system configuration.
