[Overview of medical care system]
FIG. 1 is a schematic diagram for explaining the configuration of a medical care system 1000 according to the present embodiment. As shown in FIG. 1, a medical medical care system (hereinafter also referred to as a medical care system) 1000 includes one medical medical care device (hereinafter also referred to as a medical care device) 10 and one PC for analysis (Personal Computer). And 20. The medical treatment apparatus 10 is, for example, a chair unit for a user such as an operator to treat a patient. The analysis PC 20 is communicably connected to the medical care apparatus 10 and detects an abnormality occurring in the medical care apparatus 10. The analysis PC 20 is an embodiment of the “detection device”.

[Configuration of medical treatment apparatus]
FIG. 2 is a block diagram for explaining the configuration of the 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. , A basin unit 2 and a lighting device (e.g. dental light) 7.

  The medical treatment chair 1 has a headrest 1a for supporting the patient's head, a backrest 1b for supporting the patient's back, a seat 1c for supporting the patient's tail, a footrest 1d for supporting the patient's foot, and a seat driving unit 11 Equipped with Each of these configurations changes the position and posture of the medical chair 1 by the operation of a movable unit 117a, which will be described later, included in each of the configurations.

  Here, the main configuration of the sheet drive unit 11 will be described with reference to FIG. FIG. 3 is a schematic view for explaining the configuration of the sheet drive unit 11 according to the present embodiment. As shown in FIG. 3, the seat drive unit 11 includes an oil pan 111, an oil pump 112, an adjustment unit 115, a hydraulic cylinder 117, and a chair control board 120. The seat drive unit 11 adjusts the operation of the movable portion 117 a coupled to the piston rod 117 b moved by the hydraulic cylinder 117.

  The oil pump 112 is connected to the oil pan 111 and sucks up the oil stored in the oil pan 111. The oil drawn up by the oil pump 112 is supplied to the hydraulic cylinder 117 via the adjustment unit 115. The adjustment unit 115 adjusts the amount of oil supplied to the hydraulic cylinder 117. Adjustment unit 115 includes an on-off valve 113 and a servomotor 114. On the chair control board 120, a central processing unit (CPU) 121, a read only memory (ROM) 122, a random access memory (RAM) 123, and the like are mounted. The chair control board 120 and the CPU 121 are an embodiment of the “control unit”.

  The CPU 121 is connected to the servomotor 114 and drives the servomotor 114 by applying a constant voltage according to a drive signal. The opening degree of the on-off valve 113 changes in accordance with the rotation angle (position) of the servo motor 114 which has been driven. The amount of oil supplied from the oil pump 112 to the hydraulic cylinder 117 changes in accordance with the opening degree of the on-off valve 113, and the hydraulic pressure in the conduit also changes accordingly. When the hydraulic pressure in the conduit changes, the piston rod 117b housed in the hydraulic cylinder 117 moves. Specifically, when the on-off valve 113 is slightly opened in the forward rotation direction by driving the servomotor 114 by the drive signal from the CPU 121, the piston rod 117b moves slowly in the right direction. Furthermore, if the opening degree of the on-off valve 113 becomes large, the piston rod 117b moves quickly in the right direction. On the other hand, when the on-off valve 113 is slightly opened in the reverse direction by driving the servomotor 114 by the drive signal from the CPU 121, the piston rod 117b moves slowly in the left direction. Furthermore, if the opening degree of the on-off valve 113 becomes large, the piston rod 117b moves quickly in the left direction. When the on-off valve 113 is closed, the piston rod 117b is stopped.

  The piston rod 117b of the hydraulic cylinder 117 is coupled to the movable portion 117a. The movement of the piston rod 117b in the hydraulic cylinder 117 operates the movable part 117a coupled to the piston rod 117b. The movable portion 117a is connected to at least one of the head rest 1a, the backrest 1b, the seat 1c, and the footrest 1d. For example, the movable portion 117a of the seat 1c is a vertical movement axis for raising or lowering the seat. In the present embodiment, although the hydraulic cylinder 117 is included in the seat drive unit 11, at least one or more hydraulic cylinders are provided for each of the headrest 1a, the backrest 1b, the seat 1c, and the footrest 1d. 117 may be included.

  The seat 1c is raised or lowered based on the operation of the sheet drive unit 11 as described above. Each of the headrest 1a, the backrest 1b, and the footrest 1d moves vertically or horizontally with respect to the seat 1c based on the operation of the seat drive unit 11. When the headrest 1a, the backrest 1b, and the footrest 1d are vertically positioned with respect to the seat 1c, the patient sitting on the medical chair 1 is in the sitting position. When the head rest 1a, the backrest 1b, and the footrest 1d are positioned in the horizontal direction with respect to the seat 1c, the patient sitting on the medical chair 1 is in the supposing position. As described above, the seat driving unit 11 drives the headrest 1a, the backrest 1b, the seat 1c, and the footrest 1d to change the posture of the medical chair 1.

  The head rest 1a, the backrest 1b, the seat 1c, and the footrest 1d are not limited to those driven by the dedicated sheet driving unit 11, but may be used as one or more sheet driving units 11. .

  The potentiometer 116 is connected to the movable portion 117a, and acquires information corresponding to the operation of the movable portion 117a. The potentiometer 116 is an embodiment of the “acquisition unit”. Specifically, the potentiometer 116 includes a pinion 116a attached to the fixed part of the medical care apparatus 10, and engages with a rack provided on the movable part 117a. When the movable portion 117a coupled to the piston rod 117b operates according to the operation of the hydraulic cylinder 117, the pinion 116a engaged with the rack rotates. The potentiometer 116 detects the rotation of the pinion 116a and outputs a voltage corresponding to the rotation. For example, when the rotation angle of the servomotor 114 is a reference angle (for example, 0 degree) and the open / close valve 113 is completely closed, the hydraulic cylinder 117 stops and the movable portion 117a also stops. In this case, the potentiometer 116 outputs a voltage corresponding to the stop of the movable portion 117a. The CPU 121 monitors the output voltage of the potentiometer 116.

  When the rotation angle of the servomotor 114 changes from the reference angle and the on-off valve 113 starts to open, the hydraulic cylinder 117 starts operating and the movable portion 117a also starts operating. In this case, the potentiometer 116 outputs a voltage corresponding to the amount of movement of the movable portion 117 a (rotation of the pinion 116 a engaged with the rack). As the operation amount of the movable portion 117a increases, the output voltage of the potentiometer 116 increases. The CPU 121 monitors the output voltage of the potentiometer 116.

  When the output voltage of the potentiometer 116 reaches the target value (that is, the voltage value corresponding to the movement of the movable portion 117a to the target position), the CPU 121 drives the servomotor 114 by the drive signal to drive the on-off valve 113. It closes and the hydraulic cylinder 117 is stopped. Thereby, the movable portion 117a coupled to the piston rod 117b is stopped as the hydraulic cylinder 117 is stopped.

  As described above, in the sheet driving unit 11, the potentiometer 116 detects the operation of the movable unit 117a, and a signal based on the detection is fed back to the CPU 121. The CPU 121 controls the servomotor 114 of the adjustment unit 115 based on the signal fed back from the potentiometer 116.

  Returning to FIG. 2, the foot controller 5 has a plurality of switches (pedals) that receive the user's stepping operation. The user can assign a predetermined function to each of the plurality of switches.

  For example, the user can assign the 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 driving unit 11. The CPU 121 of the seat drive unit 11 drives the headrest 1 a and the like based on the control signal.

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

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

  The tray table 3 is used as a storage table at the time of medical treatment. The tray table 3 is connected to the medical chair 1 or an arm (not shown) extending from the floor. Therefore, the user can manually rotate, horizontally move, and vertically move the tray table 3 with respect to the medical chair 1.

  The controller 9 is provided below the tray table 3.

The control device 9 includes an operation control unit 12, a medical instrument driving unit 14, a display monitor control unit 15, and a holding release identification unit 19. Each of these units is configured by an operation control board, a drive control board, a monitor control board, and a CPU, a ROM, a RAM, and the like mounted on the holding release specific control board.

  The medical instrument 4 is, for example, an instrument for dental practice such as an air turbine handpiece, a micromotor handpiece, a scaler, a three-way syringe, and a vacuum syringe. The medical instrument 4 is not limited to these, and may be an intraoral camera, an irradiator for photopolymerization, a root canal length measuring device, a three-dimensional scanner, a root canal magnifier, etc., a dental mirror, a syringe, And non-powered devices such as filling devices.

  In the medical treatment apparatus 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 removed from the instrument holder 50, the holding by the instrument holder 50 is released, and the medical instrument 4 is in a selected state (selected state).

  Each medical treatment instrument 4 is connected to a medical treatment instrument drive unit 14 provided in the control device 9. The medical instrument driving unit 14 drives the respective medical instruments 4 based on the user's foot 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 of the air turbine handpiece. As described above, the medical instrument drive unit 14 drives the medical instrument 4 based on the operation of the user on 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 identification unit 19 provided in the control device 9. The holding release specifying unit 19 specifies that holding of the medical instrument 4 by the instrument holder 50 has been released, and outputs a signal indicating the specification result to the operation control unit 12. The operation control unit 12 specifies the medical instrument 4 in the selected state based on the signal from the holding and release specifying unit 19.

  The basin unit 2 is provided on the side of the medical chair 1, as shown in FIG. The basin unit 2 includes a bowl 2a in which a drainage port is formed, a cup base 2b on which a cup is placed, and a water tap 2c for supplying water to the cup. The patient can gargle using the water supplied to the glass by the faucet 2c.

  As shown in FIG. 2, the basing unit 2 includes a basing control unit 16. The basin control unit 16 controls the flow of water used in the medical care apparatus 10. The baseline control unit 16 is configured of a CPU, a ROM, a RAM, and the like mounted on a baseline control board (not shown).

  Further, the basis unit 2 includes a lighting control unit 17. The lighting control unit 17 controls lighting and turning off of the lighting device 7. The illumination control unit 17 is configured by a CPU, a ROM, a RAM, and the like mounted on an illumination control substrate (not shown).

  Furthermore, the baseline unit 2 includes a history collection unit 18 that collects history information in the medical care apparatus 10. The history collection unit 18 is configured by a CPU, a ROM, a RAM, and the like mounted on a history collection substrate (not shown), and is provided inside the maintenance door 2 d of the baseline unit 2. For this reason, the memory 18b such as the ROM and the RAM can not be removed from the history collection substrate unless the maintenance door 2d is opened using a predetermined tool. The history collection unit 18 is an embodiment of the “collection unit”. In addition, the memory 18 b is an embodiment of the “storage unit”.

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

  The history information collected by the history collection unit 18 is stored in the memory 18 b removable from the history collection substrate. The memory 18 b is a storage medium configured of 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 only by removing the memory 18b from the history collection substrate and connecting it to the analysis PC 20 without connecting the wiring from the analysis PC 20 to the output port 18a. Can. The output port 18 a may not be provided in the history collection substrate. When the output port 18 a is not provided on the history collection substrate, the analysis PC 20 directly accesses the memory 18 b to acquire history information from the medical care apparatus 10.

  For communication between control boards in the medical care apparatus 10, related known techniques such as CAN (Controller Area Network) communication are applied. In the medical care apparatus 10, all control boards such as the chair control board 120, the operation control board, the drive control board, the monitor control board, the holding release specific control board, the beacon control board, and the illumination control board communicate with each other by CAN communication. , Control each other by sharing their situation. In CAN communication, communication data is communicated between control boards using communication data including information on control in each control board as a communication packet. In communication between control boards, if communication data including information on control in each control board is transmitted / received, it is not necessary to convert it into a communication packet. Here, the information related to control includes information such as switches controlled by each control board, sensors, actuators, status, and the like.

  By connecting the history collection substrate so as to be able to perform CAN communication with another control substrate, the history collection unit 18 can collect information on control in each control substrate as history information. The history collection unit 18 receives information on chair unit position control (specifically, the output voltage of the potentiometer 116) sent from the chair control board 120, for example, from the operation control unit 12 via CAN communication. Various control from communication packet including information of coming medical treatment instrument 4, information of cup water supply electromagnetic valve control sent from the basin control part 16, information of lighting control of the lighting device 7 sent from the lighting control part 17, etc. Information on the is collected as history information.

  The display monitor 6 is connected to the operation control unit 12 via the display monitor control unit 15. The display monitor control unit 15 causes the display monitor 6 to display an image based on the command from the operation control unit 12.

[Configuration of PC for analysis]
FIG. 4 is a block diagram for explaining the configuration of the analysis PC 20 according to the present embodiment. As shown in FIG. 4, the analysis PC 20 includes a CPU 200 that executes various programs including an operating system (OS: Operating System), and a memory unit 212 that temporarily stores data necessary for the execution of the programs in the CPU 200. And a hard disk drive (HDD) 210 storing a program to be executed by the CPU 200 in a non-volatile manner. A program for realizing analysis is stored in advance in the HDD 210, and such a program is stored in a storage medium such as a CD-ROM (Compact Disk-Read Only Memory) 214a by the CD-ROM drive 214 or the like. Read.

  The CPU 200 receives an instruction from the user via the input unit 208 including a keyboard, a mouse and the like, and outputs an analysis result and the like analyzed by the execution of the program to the display unit 204. The respective parts are connected to one another via a bus 202. The interface unit 206 can be connected to the output port 18 a of the medical care apparatus 10. In addition, although the case where the connection between the analysis PC 20 and the medical care device 10 is connected by wire via the output port 18a has been described, it may be connected wirelessly.

[Collection of history information by history collection unit]
Next, in the medical care apparatus 10 according to the present embodiment, a process in which the history collection unit 18 collects history information from each control board will be described. FIG. 5 is a diagram for explaining the contents of a communication packet being communicated between control boards. The contents of the communication packet shown in FIG. 5 are an example, and other data are of course allocated to the communication packet.

  Each control board is performing CAN communication, and communicates information such as a switch controlled by each control board, a sensor, an actuator, and a status (information related to control) on a communication packet. In the communication packet, the format is determined in advance such that information such as switches, sensors, actuators, and status controlled by each control board can be identified in all control boards provided in the medical care apparatus 10 .

  Specifically, in the communication packet shown in FIG. 5, “1” is given as the communication packet ID to the drive control board (the medical instrument drive unit 14) and “2” as the communication packet ID to the chair control board 120 (the sheet drive unit 11). “3” is assigned as the communication packet ID to the main control board (the main control unit 16), and “4” is assigned as the communication packet ID to the operation control board (the operation control section 12).

  In the communication packet with the communication packet ID "1", the information on sensor A controlled by the medical instrument driver 14 is "DATA1", the information on sensor B is "DATA2", and the information on sensor C is "DATA3" Information of status A is allocated to “DATA 4”. The sensor A is, for example, a sensor for detecting the state of a selection solenoid valve of the medical instrument 4a (air turbine hand piece) controlled by the medical instrument drive unit 14. The sensor B is, for example, a sensor for detecting the state of the air solenoid valve of the medical treatment instrument 4 c (micromotor handpiece) controlled by the medical treatment instrument drive unit 14. The sensor C is, for example, a sensor for detecting the state of the water solenoid valve of the medical treatment instrument 4 d (scaler) controlled by the medical treatment instrument drive unit 14. The status A is, for example, information indicating the status of the servomotor driven by the medical instrument drive unit 14.

  Information of each actuator (for example, hydraulic cylinder 117, piston rod 117b, and movable portion 117a shown in FIG. 3) controlled by the sheet drive unit 11 is assigned to the communication packet of the communication packet ID "2". Specifically, in the communication packet with communication packet ID "2", the information of actuator A is "DATA 1", the information of actuator B is "DATA 2", the information of actuator C is "DATA 3", and the information of actuator D is Information is assigned to "DATA 4" respectively. The actuator A is, for example, an actuator provided to the headrest 1 a of the medical chair 1. The actuator B is, for example, an actuator provided on the backrest 1 b of the medical chair 1. The actuator C is, for example, an actuator provided on the seat 1 c of the medical chair 1. The actuator D is, for example, an actuator provided on the footrest 1 d of the medical chair 1.

  Similarly, in the communication packet with the communication packet ID "3", the information on the actuator E controlled by the basing controller 16 is "DATA 1", the information on the actuator F is "DATA 2", and the information on the actuator G is "DATA 3". The information of status B is assigned to “DATA 4”. In the communication packet with communication packet ID "4", the information on switch A controlled by operation control unit 12 is "DATA 1", the information on switch B is "DATA 2", the information on switch C is "DATA 3", The information of the switch D is assigned to "DATA 4".

  Each control board carries information on switches, sensors, actuators, status, etc. on the communication packet shown in FIG. 5 and transmits it to the other control boards so that all control boards operate in cooperation with each other. Is possible. Therefore, by connecting the history collection board to the wiring capable of receiving the communication packet, the history collection unit 18 can collect information on control in each control board from the plurality of control boards as history information. Become.

  FIG. 6 is a diagram for explaining the history information collected by the history collection unit 18. In addition, in FIG. 6, the example about the log information regarding control of the actuator of the seat 1c is shown.

  In the communication packet communicated between the control boards, the information is identified by attaching an event code in accordance with the format shown in FIG. For example, when the information on the actuator C ("DATA 3") of the chair control board 120 (communication packet ID "2") is included in the communication packet, the history collection unit 18 is information for identifying the chair control board 120. A communication packet ID "2" and an event code "210003" corresponding to information for identifying the actuator C are generated and stored in the history information. Therefore, since the history information collected by the history collection unit 18 always stores the communication packet ID and the event code corresponding to the information for identifying the actuator, sensor, etc., information on which actuator, sensor, etc. of which control board It can be identified. Note that “210001” is an event code in the information of the actuator A (“DATA 1”) of the chair control board 120 (communication packet ID “2”), and “210002” is an event code in the information of the actuator B (“DATA 2”). However, “210004” is assigned as an event code to the information of the actuator D (“DATA 4”).

  Furthermore, the history collection unit 18 generates an event parameter corresponding to the data included in the communication packet and stores it in the history information. The event parameter indicates the output voltage of the potentiometer 116 corresponding to the operation of the movable portion 117a. For example, when the output voltage of the potentiometer 116 is V1, the event parameter is "V1". In the history information collected by the history collection unit 18, information of date and time, etc. is also stored together with the event code and the event parameter. As will be described later, the history collection unit 18 does not store all communication packets, but changes the time difference of the communication packet ID and data included in the communication packet (when an event occurs). , Event code and event parameters are generated and stored in history information.

  In CAN communication, information is added to a communication packet and transmitted to another control board even if there is no change in an object controlled by the control board. For example, even if the output voltage of the potentiometer 116 does not change from V1 at the previous transmission, information corresponding to the same event code and event parameter as at the previous transmission is placed on the communication packet and transmitted to the control board. Therefore, if the history collection unit 18 collects all the information of the communication packet to be transmitted and stores it in the memory 18b, the amount of information to be stored becomes enormous, and the capacity which can be stored in the memory 18b is exceeded in a short time. It will

  Therefore, the history collection 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. 7 is a graph showing an example of the time change of the output voltage of the potentiometer 116 during the ascent of the seat 1c. In FIG. 7, the horizontal axis represents time, and the vertical axis represents the output voltage of the potentiometer. On the horizontal axis, sampling times (t0, t1, t2,...) At which the history collection unit 18 collects history information (output voltage of the potentiometer 116) from the communication packet are shown. On the vertical axis, the output voltage of the potentiometer 116 for each sampling time is shown.

  In the example shown in FIG. 7, the seat 1c is elevated from time t0 to time t25, and the output voltage of the potentiometer 116 at time t0 when the seat 1c is at the lowest position is V0, the seat The output voltage of the potentiometer 116 at time t25 when 1c is at the highest position is VMAX. The voltage value corresponding to V0 may be 0 or a value larger than 0. The output voltage of the potentiometer 116 becomes the target value VMAX when the movable part 117a moves to the target position, the on-off valve 113 closes, and the hydraulic cylinder 117 stops. That is, at time t25 when the output voltage of the potentiometer 116 becomes VMAX, the seat 1c stops at the target position.

  As shown in FIG. 7, the output voltage of the potentiometer 116 at time t1 is V1. In this case, as shown in FIG. 6, the history collection unit 18 collects information of the output voltage of the potentiometer 116 corresponding to the seat 1c at the time (t1) of the date (2017/5/25), and the event code The information of "210003" and the event parameter "V1" is stored in the memory 18b as history information.

  Next, as shown in FIG. 7, the output voltage of the potentiometer 116 at time t2 is V2 changed from V1. In this case, as shown in FIG. 6, the history collection unit 18 collects information on the output voltage of the potentiometer 116 corresponding to the seat 1c at the time (t2) of the date (2017/5/25), and the event code Information with an event parameter of “210003” and “V2” is stored in the memory 18 b as history information. Similarly, while the seat 1c is elevated from time t3 to time t25, the history collection unit 18 continues to collect information on the output voltage of the potentiometer 116.

  As described above, the medical treatment apparatus 10 according to the present embodiment modifies the existing substrate and the system configuration in order to collect history information of various controls from communication packets communicated among a plurality of control substrates. History information can be collected. In particular, the history collection board only receives and monitors communication packets, and does not affect the control of the entire medical care apparatus 10. That is, since an algorithm for collecting history information does not affect the system of the medical care apparatus 10, a mechanism for easily collecting the history information without modifying the existing substrate or system configuration is to be constructed. Can.

  Furthermore, the history collection unit 18 collects, from the communication packet, information that has changed with respect to the history information stored previously, and stores the information as history information in the memory 18 b. For this reason, as for the history information stored in the memory 18b, the amount of information can be suppressed as compared with the case where all the information related to 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 substrate and the history information stored in the memory 18b is taken out, the analysis computer 20 can be obtained by suppressing the amount of information of the history information stored in the memory 18b. Can retrieve the history information stored in the memory 18b in a short time.

  Of course, the history collection unit 18 stores all the information contained in the communication packet, even if there is no change in the control target controlled by the control board (ie, no event occurs) if there is no restriction on the amount of information. May be

[Outline of anomaly detection]
As described above, in the medical care apparatus 10 according to the present embodiment, information on control in each control board is shared among the control boards by the communication packet, 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, the analysis PC 20 detects an abnormality in the medical care apparatus 10 based on the history information acquired by the history collection unit 18 using such an existing substrate or system configuration as it is. Do. Hereinafter, in the medical treatment system 1000 according to the present embodiment, processing for determining an abnormality of the medical treatment apparatus will be described.

  FIG. 8 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. 8, the medical care apparatus 10 outputs the history information stored in the memory 18 b for storing the history information, the memory 18 b for storing the collected history information, and the history information stored in the memory 18 b to the analysis PC 20. And an output port 18a of In the medical care apparatus 10 illustrated in FIG. 2, the output port 18 a is illustrated in the frame of the history collection unit 18 to indicate that the output port 18 a is mounted on the history collection substrate that configures the history collection unit 18. However, in the medical care apparatus 10 illustrated in FIG. 8, the history collection unit 18 and the output port 18 a are illustrated separately in order to describe 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 compare with the reference information using the history information itself, or may compare with the reference information after converting the history information by calculation or the like. The storage unit 25 stores reference information used by the comparison unit 23, the determination result obtained by the determination unit 21, and the like. The determination unit 21 determines the presence or absence of an abnormality of the medical care device 10 based on the comparison result obtained by the comparison unit 23. The determination unit 21 can perform determination, prediction, and the like of a failure in the medical care apparatus 10 by determining the presence or absence of an abnormality of the medical care apparatus 10. The updating unit 24 updates the reference information used by the comparing unit 23 to an appropriate one based on the comparison result obtained by the comparing unit 23. The analysis computer 20 is a detection device that is communicably connected to the medical care device 10 and detects an abnormality in the medical care device 10, and may be provided with at least one of the comparison unit 23 and the determination unit 21. . Further, the analysis computer 20 may not have the updating unit 24. In this case, predetermined fixed reference information such as a design value is used for abnormality detection.

[Anomaly detection related to chair unit position control]
In the medical care system 1000 according to the present embodiment, abnormality of the medical care apparatus 10, in particular, the chair using the information on chair unit position control (specifically, the output voltage of the potentiometer 116) sent from the chair control board 120. Detect an abnormality related to unit position control. The abnormality relating to the chair unit position control includes the abnormality relating to the movable portion 117a operated by the control of the seat driving portion 11 shown in FIG.

  FIG. 9 is a flowchart for explaining the abnormality detection process executed by the medical care system 1000 according to the present embodiment. The abnormality detection process shown in FIG. 9 is performed in a state where the analysis PC 20 is connected to the output port 18 a of the history collection unit 18 included in the medical care apparatus 10. The abnormality detection process may be executed when the analysis PC 20 is connected to the output port 18a, or when the analysis PC 20 is connected to the output port 18a, an instruction is given from the user via the input unit 208. It may be executed upon receiving. In addition, the abnormality detection process may be performed at predetermined intervals (for example, every time the seat 1c or the like completes a series of operations) in a state where the analysis PC 20 is connected to the output port 18a, It may be performed (e.g., every sampling time). Also, the user or the maintenance worker may be able to arbitrarily set the execution timing of the abnormality detection process.

  As shown in FIG. 9, the medical care apparatus 10 outputs the output voltage of the potentiometer 116 stored in the memory 18b as history information to the analysis PC 20 (S11). Specifically, the medical care apparatus 10 includes information ("DATA 1") of the output voltage of the potentiometer 116 corresponding to the actuator A (hydraulic cylinder 117, movable portion 117a) provided in the headrest 1a, and an actuator provided in the backrest 1b. B (hydraulic cylinder 117, movable portion 117a) output voltage information ("DATA 2") of the potentiometer 116, potentiometer 116 corresponding to the actuator C (hydraulic cylinder 117, movable portion 117a) provided on the seat 1c Output voltage information ("DATA 3"), output voltage information ("DATA 4") of the potentiometer 116 corresponding to the actuator D (hydraulic cylinder 117, movable part 117a) provided on the footrest 1d to the analysis PC 20 Output.

  On the other hand, the analysis PC 20 acquires history information from the memory 18b via the interface unit 206 (S21). Next, the analysis PC 20 calculates a standard deviation from the output voltage of the potentiometer 116 included in the acquired history information by the comparison unit 23 (S22).

  Here, the standard deviation will be described with reference to FIG. As described above, FIG. 7 is a graph showing an example of the time change of the output voltage of the potentiometer 116 during the ascent of the seat 1c. First, the analysis PC 20 calculates the inclination of the graph at each sampling interval, such as between time t1 and time t2, between time t2 and time t3, and between time t3 and time t4. Then, the analysis PC 20 calculates a standard deviation (hereinafter also referred to as an actual standard deviation) using the inclination of the graph calculated at each sampling interval. The standard deviation may be calculated using a known equation, for example, the square root of the difference between the slope of the graph at each sampling interval and the average value of the slope of the graph, and then the positive square root of it is calculated. do it. That is, the analysis PC 20 calculates the magnitude of the variation as the standard deviation for the data of the time change of the output voltage of the potentiometer 116.

  Returning to FIG. 9, the analysis PC 20 compares the actual standard deviation calculated by the comparison unit 23 with the standard deviation serving as a reference (hereinafter, also referred to as a reference standard deviation) (S23).

  Here, the standard deviation is described. FIG. 10 is a graph as a reference of the time change of the output voltage of the potentiometer 116 during the ascent of the seat 1c. The graph shown in FIG. 10 is an ideal graph when the movable part 117a of the seat 1c operates extremely smoothly. Specifically, in this reference graph, the time change of the sampling time is proportional to the change of the output voltage of the potentiometer 116, and the graph is approximately straight. Therefore, the reference standard deviation in this case is a value as close to 0 as possible. At the time of initial introduction of the medical care apparatus 10, the time change of the output voltage corresponding to the standard deviation becomes a graph as shown in FIG. 10, but the operation speed of the movable portion 117a decreases or the operation It is not smooth. Such age-related deterioration varies among individuals. Therefore, in the present embodiment, the average value of the past standard deviations calculated in the medical care apparatus 10 is used as the reference standard deviation. That is, in the medical care apparatus 10, the standard standard deviation unique to the apparatus is used in consideration of aging.

  In the process of S23, the analysis PC 20 compares the standard deviation (actual standard deviation) of the graph based on the actual data shown in FIG. 7 with the standard deviation (standard standard deviation) of the reference graph shown in FIG. Calculate the difference. Then, the analysis PC 20 compares the difference with the threshold value stored in advance in the storage unit 25. In this example, the output voltage of the potentiometer 116 corresponds to one embodiment of "correspondence information", and the reference standard deviation and the threshold of the reference graph shown in Fig. 10 correspond to one embodiment of "reference information". Corresponds to

  Returning to FIG. 9, the analysis PC 20 detects an abnormality of the medical care apparatus 10, in particular, an abnormality related to chair unit position control such as the seat 1c by the determination unit 21 (S24). When the PC 20 for analysis determines that the difference between the actual standard deviation and the reference standard deviation is larger than the threshold based on the comparison result obtained in the process of S23 (YES in S24), according to the degree of abnormality. In a different mode, the display unit 204 reports that an abnormality has occurred (S25). For example, different warning images are displayed on the display unit 204 according to the difference between the difference between the actual standard deviation and the reference standard deviation and the threshold. For example, a warning image is displayed on the display unit 204, such as prompting repair as the degree of deviation increases. Not only the display unit 204 but also a speaker or a lamp (not shown) may be used to notify of an abnormality.

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

  Note that although the abnormality detection processing shown in FIG. 9 is performed in a state where the analysis PC 20 is connected to the output port 18a of the history collection unit 18, of course, the memory 18b is removed from the history collection substrate and analyzed. It is applicable also in the state where it was connected to PC20 for. In this case, the process of S11 executed by the medical care apparatus 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 communication data transmitted and received by the chair control board 120. The history information includes information on the output voltage of the potentiometer 116 corresponding to the operation of the movable portion 117a. The comparison unit 23 calculates a standard deviation from the output voltage of the potentiometer 116 collected as history information, and compares the calculated standard deviation with a standard deviation as a reference included in reference information stored in the storage unit 25 in advance. Do. Based on the comparison result by the comparison unit 23, the determination unit 21 determines the presence or absence of an abnormality in the medical care apparatus 10, in particular, an abnormality regarding chair unit position control.

  As described above, the medical care system 1000 can detect an abnormality related to chair unit position control based on the history information of various controls collected from communication packets communicated among a plurality of control boards. As a cause of such an abnormality, bending of the shaft in the movable portion 117a such as the seat 1c or the shaft is caught, oil leakage, etc. can be considered.

  Further, since the medical care system 1000 detects an abnormality related to chair unit position control based on history information of various controls collected from communication packets communicated among a plurality of control boards, an abnormality related to chair unit position control In order to detect, it is not necessary to provide separately the sensor and the structure which processes the result detected by the said sensor. As a result, the medical care system 1000 can detect an abnormality in the medical care apparatus 10 without changing the existing substrate 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 history information stored in the memory 18 b via the interface unit 206, and compares the acquired history information with reference information using the acquired history information. Of course, the medical care system 1000 may acquire history information directly from the history collection unit 18 by the comparison unit 23 without providing the memory 18 b. Further, the storage unit for storing history information may be included in the analysis computer 20 instead of the medical care device 10.

  In the medical care system 1000, the updating unit 24 updates the standard deviation to be the average value of past standard deviations based on the actual standard deviation. As a result, even when there is a variation in aged deterioration depending on the individual, a standard standard deviation corresponding to each medical treatment apparatus 10 is applied, so that an abnormality is erroneously detected by largely affecting the variation in aged deterioration. It can be prevented as much as possible. Furthermore, it is not necessary to teach the standard deviation to the analysis PC 20 each time the abnormality detection process is performed.

  In the medical care system 1000, when the determination unit 21 detects an abnormality related to the chair unit position control, the display unit 204 notifies that the abnormality has occurred in a different manner according to the degree of the abnormality. This makes it easy for the user or maintenance worker to recognize the degree of abnormality.

Further, information on the rotation angle of the servomotor 114 may be included in the history information, and an abnormality related to chair unit position control may be detected by comparing the rotation angle with the reference rotation angle included in the reference information. . That is, the medical treatment system according to the modification may use the rotation angle of the servomotor 114 to detect an abnormality related to the chair unit position control.

  In the medical care system 1000 according to the present embodiment, as one embodiment of abnormality detection, the output voltage of the potentiometer 116 is used to detect an abnormality related to chair unit position control while the seat 1c is rising. . However, the present invention is not limited to this, and the output voltage of the potentiometer 116 during the lowering of the seat 1c may be used to detect an abnormality related to the chair unit position control. Moreover, you may detect abnormality in any operation | movement of the structure contained not only in the seat 1c but the medical chair 1, such as the headrest 1a, the backrest 1b, and the footrest 1d. Furthermore, the configuration is not limited to the configuration included in the medical treatment chair 1, and any configuration is possible as long as the operation can be detected by collecting history information from the communication data transmitted and received on the control board by the history collecting unit 18. An abnormality can be detected by the medical care system 1000 according to the present embodiment.

[Anomaly detection in the medical device itself]
The medical care system 1000 according to the present embodiment is to detect an abnormality of the medical care device 10 by the analysis computer 20 connected to the medical care device 10. However, the medical treatment apparatus 10 itself may detect an abnormality. FIG. 11 is a block diagram for explaining a function related to abnormality detection of the medical care apparatus 10a according to the modification. The medical care apparatus 10a illustrated 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 care apparatus 10a collects history information from the communication data transmitted and received by the chair control board 120 by the history collection unit 18 and stores the history information in the memory 18b. The comparison unit 23 acquires history information stored in the memory 18 b, and compares the acquired history information with reference information stored in the storage unit 25 using the acquired history information. The determination unit 21 determines, based on the comparison result by the comparison unit 23, whether there is an abnormality in the medical care apparatus 10a, in particular, an abnormality related to chair unit position control. The update unit 24 updates the reference information based on the history information. As described above, the medical care apparatus 10a relates to chair unit position control because it detects an abnormality related to chair unit position control based on the history information of various controls collected from communication packets communicated among a plurality of control boards. In order to detect an abnormality, 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 apparatus 10a without modifying the existing substrate or system configuration.

[Collaboration with other medical devices]
The medical care system 1000 according to the present embodiment detects an abnormality by collecting history information of the medical care device 10 installed in a doctor's office, but the history information collected by the medical care device 10 and the presence or absence of an abnormality At least one of the determination results of may be shared with other medical devices in the same clinic. Furthermore, the medical care system 1000 can set at least one of the history information collected by the medical care device 10 installed in a certain clinic and the determination result of the presence or absence of abnormality with the medical care device installed in another clinic. You may share it. For example, medical treatment systems installed in each of a plurality of clinics are respectively connected to servers on a cloud operated by a manufacturer, and history information collected by each medical treatment system and determination results as to presence or absence of abnormality May be shared among multiple medical care systems.

  Here, FIG. 12 is a schematic diagram for explaining a system configuration in which a plurality of medical care medical care systems are connected. In the system shown in FIG. 12, the analysis computer 20A of the medical treatment system 1000A installed in A dental clinic and the server 201 on the cloud 200 are connected via a network line. In this system, similarly, the analysis computer 20X of the medical care system 1000X installed in another X dental clinic and the server 201 on the cloud 200 are connected via a network line. That is, in the system shown in FIG. 12, at least one of the history information of the medical care apparatus 10 collected by the plurality of medical care systems 1000 installed from A dental clinic to X dental clinic and the determination result of the presence or absence of abnormality is The plurality of medical care systems 1000 can be shared via the server 201 on the cloud 200. The analysis computer 20 provided in each clinic is connected to the network via the interface unit 206.

  The server 201 on the cloud 200 aggregates the history information of the medical care apparatus 10 collected from a plurality of clinics and the determination result of the presence or absence of abnormality to calculate the average value of the whole, or the medical treatment collected from clinics in a specific area The history information of the apparatus 10 and the determination result of the presence or absence of abnormality may be totaled to calculate the average value of the specific area. In addition, the server 201 provides improvement information of the medical care apparatus 10 to each clinic based on the history information of the medical care apparatus 10 and the determination result of the presence or absence of abnormality, or the history information of the medical care apparatus 10 in other clinics and the presence or absence of abnormality The proposal information about the usage method and the management method of the medical treatment apparatus 10 may be provided by comparing with the determination result of (1).

  The analysis computer 20 does not have to be installed in each doctor's office, and the history information collected by the medical treatment apparatus 10 of each doctor's office is transmitted to the server 201 on the cloud 200 by the communication unit (for example, transmission server). The system should be configured to be able to do so.

[Share PC for Analysis]
The analysis computer 20 does not have to be provided for each medical treatment apparatus 10. For example, by connecting the common analysis computer 20 to a plurality of medical care devices 10 installed in one clinic, the analysis computer 20 detects the presence or absence of an abnormality in the plurality of medical care devices 10 installed in the medical office. You may judge.

  For example, as shown in FIG. 12, the server 201 on the cloud 200 may be provided with the function of the analysis computer 20. Specifically, the server 201 on the cloud 200 may have the function of the analysis computer 20A of the medical care system 1000A and the function of the analysis computer 20X of the medical care system 1000X. In this case, the server 201 may collect history information of the medical care apparatus 10A, and determine the presence or absence of an abnormality of the medical care apparatus 10A based on the collected history information and the reference information stored in advance. Similarly, the server 201 may collect history information of the medical care apparatus 10X, and determine the presence or absence of an abnormality of the medical care apparatus 10X based on the collected history information and the reference information stored in advance. Furthermore, the server 201 may select at least one of history information collected from a plurality of medical treatment apparatuses 10 installed from A dental clinic to X dental clinic and at least one of the judgment results of the presence or absence of abnormality based on them. You may share between them.

  In addition, when a common analysis computer 20 is connected to a plurality of medical care devices 10 installed in a single clinic, or as shown in FIG. 12, in a plurality of medical care devices 10 installed in a plurality of clinics When the common analysis computer 20 (server 201) is connected, the analysis computer 20 may analyze the abnormality of the medical care apparatus 10 based on the determination result of the integrated abnormality. For example, in the present embodiment, the difference between the actual standard deviation calculated from the output voltage of potentiometer 116 included in the history information and the reference standard deviation is compared with the threshold value stored in advance in storage unit 25. Although the abnormality of the medical treatment apparatus 10 is detected by the above, the reference standard deviation or the threshold may be updated to an appropriate value based on the determination result of the presence or absence of the abnormality in the plurality of medical treatment apparatuses 10. Specifically, the reference standard deviation may be updated to be the average value of the actual standard deviations calculated from the output voltages of the potentiometers 116 included in the history information in the plurality of medical care devices 10, and after the update. The threshold may be updated to an appropriate value based on the reference standard deviation. Also, if the reference standard deviation due to age deterioration can be predicted to be approximately the same for a plurality of medical treatment apparatuses 10, one medical treatment apparatus 10 may use the standard standard deviation for another medical treatment apparatus 10 introduced at the same time as its own. The standard standard deviation may be used, or the standard standard deviation of another medical care apparatus 10 may be updated based on the reference. In this way, the accuracy of abnormality detection in the medical care apparatus 10 is further improved.

[Other modifications]

In addition, a history collection unit (for example, a history collection server or the like) provided outside the medical care device 10 may collect history information from a plurality of medical care devices 10. Furthermore, the history collection unit provided in the specific medical treatment apparatus 10 or the history collection unit provided outside may also collect history information from medical treatment apparatuses such as an X-ray imaging apparatus and a laser treatment apparatus.

The target of collection was However, of the various types of control performed on a plurality of control boards, the history collection unit 18 only records information on chair unit position control (for example, the output voltage of the potentiometer 116) sent from the chair control board 120 as history information. It may be a collection target of

For example, the analysis computer 20 takes into consideration the determination result of the presence / absence of abnormality and information such as the usage time of the medical care apparatus 10, and advises on how to use the medical care apparatus and the addition of the medical care apparatus to establish the management of the clinic. Information may be output.

  In the present embodiment, the sheet driving unit 11 adjusts the operation of the movable unit 117a by hydraulic pressure. However, the seat drive unit 11 may adjust the operation of the movable portion 117a not only by oil pressure but also by air pressure or water pressure. Further, as shown in FIG. 13, the sheet driving unit 11 may adjust the operation of the movable portion 117 a by a mechanical mechanism. FIG. 13 is a schematic view for explaining the configuration of a sheet driving unit 11a according to a modification. Unlike the seat drive unit 11 shown in FIG. 3, the seat drive unit 11a shown in FIG. 13 does not include the oil pan 111, the oil pump 112, the on-off valve 113, and the hydraulic cylinder 117. And an adjusting portion 115a including a moving mechanism 119 such as a screw shaft (not shown) engaged with the Specifically, the pinon 114a of the servomotor 114 engages with the rack of the moving mechanism 119, and when the pinon 114a rotates according to the operation of the servomotor 114, the moving mechanism 119 engages with the pinon 114a. Move. Since the movable portion 117a is connected to the moving mechanism 119, when the moving mechanism 119 moves, the movable portion 117a also moves.
