FIG. 3 is a block diagram relating to the main configuration of the first system controller 14. The relay unit 28 has the same configuration as this.
As shown in the figure, when the first system controller 14 is mounted with the control unit 40 that controls the overall operation of the controller 14 and the above-described external memory 38 that is the third external memory, A memory I / F 41 for writing / reading data to / from the memory 38 and each connector 42 (here, only three connectors 42a, 42b, and 42c are shown, but at least as many as the number of devices to be connected are actually connectors. Communication I / F 43 for performing communication with various devices such as the first TV camera device 6 and the like which are connected via the communication I / F 43 and temporary storage of data obtained by the communication I / F 43 A first memory 44 composed of a RAM used as a work area for the control unit 40 and a second memo composed of a nonvolatile memory such as a flash memory, for example. 45 and a network I / F 46 etc. for communicating with the server 37 etc. on the in-hospital network, each of which is connected via a bus 47 and can send and receive data to and from each other. .

  The control unit 40 has a memory in which a CPU and a control program are stored, and the CPU 41 reads out and executes the control program, thereby controlling the overall operation of the controller 41.

4A and 4B are flowcharts illustrating an example of a log recording operation performed by the first system controller 14 of the present system 1 in endoscopic surgery.
As shown in FIG. 4A, the first system controller 14 first acquires device data as medical information from a device (excluding the relay unit 28) connected to the connector 42 by the communication I / F 43. 1 is temporarily stored (step (hereinafter simply referred to as “S”) 1).

  The device data is acquired when the device data transmitted independently by the device connected to the connector 42 is acquired, and when the controller 14 acquires the device data from the device connected to the connector 42 by periodic polling. There are two cases of acquisition. In addition, device data that the device independently transmits is data that is independently transmitted by the device when the device changes, such as when the state of the device changes or when the setting of the device changes. is there. The device data includes at least identification information for identifying the transmission source device, and other data related to the device, such as device status, device settings, operations performed on the device, device errors, and the like. It includes read data and the like, and is also data (history information) related to the usage history of the device.

  Subsequently, it is determined whether or not the acquired device data is initial data (S2). Specifically, it is determined whether or not device data of the same type as the device data acquired in S2 has not yet been acquired.

  Note that the same type of device data refers to data transmitted from the same device and having the same content type. For example, when the device data related to the device state has already been acquired and the device data acquired in S1 is the device data related to the device state, both devices are the same. The data has the same type of device data content. Alternatively, when the device data related to the device state has already been acquired and the device data acquired in S1 is related to the device setting, both device data have the same type of device data content. It will not be.

  If the determination result in S2 is Yes, the acquired device data is stored in the second memory 45 as a log (S3), the device data is set as the latest device data, and the process returns to S1.

  On the other hand, if the determination result in S2 is No, the device data acquired in S1 is compared with device data that is the same type of device data as the acquired device data and is set as the latest device data. It is determined whether or not there is a change in the data contents (S4). The process of S4 will be described later with reference to FIG. 4B.

  In the determination of S4, if the determination result is No, the process returns to S1, and if the determination result is Yes, the device data acquired in S1 is subsequently stored in the second memory 45 as a log ( S5), the device data is set as the latest device data.

  Subsequently, for example, a part or all of the log stored in the second memory 45 is transferred / saved to the external memory 38 which is the third external memory as necessary, for example, at a constant cycle, or the log is stored. Transfer and save to the server 37 on the hospital network (S6). Then, after storing the log in the external memory 38 or the server 37, the log is deleted from the second memory 45.

  In the flow shown in the figure, this flow ends after the processing of S5 or S6 as necessary, but after that, when the controller 14 acquires the device data, this flow is again performed. It will be started.

FIG. 4B is a flowchart showing the determination process of S4.
As shown in the figure, in this process, first, device data that is the same type of device data as the device data acquired in S1 and is set as the latest device data is held (S7).

Subsequently, it is determined whether the device data acquired in S1 is acquired by periodic polling by the controller 14 (S8).
In the determination of S8, when the determination result is Yes, the acquired device data is compared with the device data held in S7 (S9), and it is determined whether or not the content of the data has changed. (S10) When the determination result is Yes, the above-described S4 is Yes, and when the determination result is No, the above-described S4 is No.

  On the other hand, in the determination of S8, if the determination result is No, it is subsequently determined whether or not the device data acquired in S1 has been voluntarily transmitted by the device (S11). When the determination result is Yes, S4 described above is Yes, and when the determination result is No, S4 described above is No.

  In addition, after determining that it is not acquired by regular polling in S8, it is temporarily acquired by periodic polling whether it is determined whether it is what was voluntarily transmitted by the apparatus in S11. If the process shifts to Yes in S4 when it is determined that it is not, the noise may be stored in the second memory 45 when noise is acquired instead of device data. Therefore, in order to prevent this, the determination process of S11 is performed after the determination result of S8 is No.

  Thus, according to the flow shown in FIG. 4A and FIG. 4B, when device data is acquired, if the same type of device data as the device data has not yet been acquired, or the device data and the The acquired device data is saved as a log only when there is a change in the data content between the device data and the device data of the same type as the device data set as the latest device data. Therefore, logs relating to device data having the same contents are not saved, and the total data capacity of the saved logs can be reduced.

  Such a log recording operation is also performed by the relay unit 28 which is the second system controller. However, since the saved log cannot be directly transferred to the server 37 on the hospital network in the relay unit 28, in this case, it is transferred to the server 37 via the first system controller 14. It is.

FIG. 5 is a diagram illustrating an example of a format of a record relating to a log recorded by the first system controller 14.
As shown in the figure, the basic format of the record consists of a start flag (1 Byte, 0x **: fixed) that represents the beginning of the record, and time information (hour: 1 Byte) that represents the recording time in hours, minutes, and seconds. , Minutes: 1 Byte, seconds: 1 Byte total 3 Bytes), identification information (2 Bytes) indicating what type of information the corresponding record is, and data (N Byte).

  For example, in the case of a record related to date information, year / month / day information (year: 2 Byte, month: 1 Byte, day: 1 Byte) is included as data representing detailed data. In the case of a record related to device data related to the device status, information specifying the device that is the transmission source of the device data and information related to the device status of the device are included as data representing the detailed data. Further, in the case of a record related to device data related to device settings, information specifying the device that is the transmission source of the device data and information related to the device settings of the device are included as data representing the detailed data.

FIG. 6 is a diagram for explaining a specific example when the record related to the log is recorded in the memory block allocated to the second memory 45 by the first system controller 14.
As shown in the figure, Example 1 is an example in which a record (status record) relating to a log (device data related to device status) is recorded for the first time in a memory block on the second memory 45.

  In this case, first, 1. 1. Record a header record (header record) in a memory block; 2. Record a date record (date / time record); Record status records.

Thus, when a log is recorded for the first time in a memory block, a header record is always recorded first, followed by a date / time record.
Specific example 2 is another example in which logs are recorded. In the order of occurrence of device data to be recorded, records relating to device data relating to device connection (connection records), records relating to device data relating to device settings (status records). This is an example in which a record (status record) related to device data related to the state of the device is recorded, and then a record related to time (time record) is recorded.

Specific example 3 is an example when the date changes during the log recording operation.
In this case, when device data to be recorded as a log is generated for the first time after the date changes, first, a record related to the changed date is recorded, and then a record related to the device data is recorded.

  In this example, after recording a record (status record) related to device data relating to the state of the device, the date changes from 2005.01.0001 to 2005.01.02, and thereafter, the device state is recorded as a log for the first time. Since device data is generated, first, a record related to the date of 2005.01.02 is recorded, and then a record (status record) related to the device data is recorded. In the present embodiment, the date and time information is periodically saved, and the time memory is given and saved for each record block at a period finer than the date and time information, whereby the overall memory usage capacity can be reduced. Date and time information requires a data amount for the year, month, and day, and saving it in a short cycle is useless. That is, all time information can be managed by counting time records in a relatively short cycle based on date information stored in a long cycle.

  As described above, according to the present embodiment, only the device data whose data contents have changed among the acquired device data is stored as a log, so that medical information can be efficiently collected and stored. It can also be transferred if necessary. Further, since the total data capacity of the stored logs can be reduced, the capacity of the memory storing the logs can be reduced, and the system can be configured at a low cost and in a corresponding amount.

An overall configuration diagram of an endoscopic surgery system to which the medical information collecting apparatus according to the present embodiment is applied, and a block diagram showing the main configuration thereof are the same as those shown in FIGS. 1 and 2.
The block diagram relating to the main configuration of the first system controller 14 and the relay unit 28 as the second system controller is substantially the same as that shown in FIG. 3, but in this embodiment, the first Each of the system controller 14 and the relay unit 28 has a master / slave setting unit. In this example, the first system controller 14 is set as a master and the relay unit 28 is set as a slave.

  In the present embodiment, the log recording operation performed by the first system controller 14 is the same as that shown in FIGS. 4A and 4B, but the log recording operation performed by the relay unit 28 is different from that.

FIG. 7 is a flowchart illustrating an example of a log recording operation performed by the relay unit 28 in this embodiment.
As shown in the figure, the relay unit 28 is a device connected to the connector by the communication I / F (except for the first system controller 14), similarly to S1 to S2 shown in FIG. 4A. ) Is acquired as medical information and temporarily stored in the first memory (S21), and it is determined whether or not the acquired device data is initial data (S22).

  If the determination result in S22 is Yes, the acquired device data is stored in the second memory (S23), and the device data is set as the latest device data. Then, the device data is transferred to the first system controller 14 (S24), and the process returns to S21.

  On the other hand, when the determination result in S22 is No, as in S4 shown in FIG. 4A, the acquired device data and the same type of device data as the device data and set as the latest device data The data is compared, and it is determined whether there is a change in the data contents (S25).

  In the determination of S25, if the determination result is No, the process returns to S21. If the determination result is Yes, the acquired device data is subsequently stored in the second memory (S26), and the device Set the data as the latest device data. Then, the device data is transferred to the first system controller 14 (S27).

  Subsequently, it is determined whether or not the communication related to the transfer has been completed (S28). If the determination result is Yes, then as the latest device data compared with the device data transferred in S27 in S25. The set device data is deleted from the second memory (S29), and this flow ends.

  In the flow shown in the figure, this flow ends after the processing of S29 is completed, but after that, when the relay unit 28 acquires the device data, this flow is started again. is there.

  The device data transferred from the relay unit 28 to the first system controller 14 in this way is stored as a log in the second memory 45 in accordance with the processing shown in FIGS. 4A and 4B described above.

  As described above, according to the present embodiment, when device data to be recorded as a log occurs in the device data acquired from the device connected to the relay unit 28, the device data is immediately stored in the first system controller 14. For example, there is an error between the time information given by the first system controller 14 and the time information given by the relay unit 28 due to an environmental change in the ambient temperature. However, since the time information is given only by the first system controller 14, the log related to the device data acquired by the first system controller 14 and the device data acquired by the relay unit 28 are related. It is possible to prevent the time information from deviating from the log and improve the reliability of the log. It is possible. This also eliminates the need to interpolate logs between the first system controller 14 and the relay unit 28, thereby reducing the communication load between the two and enabling communication at a low rate. Since it becomes possible, the effect of noise reduction is also obtained.

  In the system according to the present embodiment, when communication between the relay unit 28 and the first system controller 14 becomes impossible due to the disconnection of the system cable 33 or the like, each of the relay unit 28 and the first system controller 14. Detects a communication error and records a record related to the communication error as a log. In such a case, since the relay unit 28 cannot transfer the device data to the first system controller 14, similarly to the first system controller 14, the device data is used as a log for the second data of the unit 28. It is saved in memory.

  In this case, a record relating to a communication error due to disconnection is recorded as a log in each of the first system controller 14 and the relay unit 28, and the relay unit 28 further records a record relating to the communication error. A record relating to the device data is recorded as a log. At this time, time information of the relay unit 28 becomes a reference.

  Here, it is considered that the record related to the communication error recorded in the first system controller 14 and the record related to the communication error recorded in the relay unit 28 are recorded at approximately the same time. The time information of the record related to the communication error recorded by the first system controller 14 is given by the controller 14, and the time of each of the record related to the communication error recorded by the relay unit 28 and the record related to the device data is recorded. The information is given by the unit 28. Therefore, even if there is a difference between the time information given by the first system controller 14 and the time information given by the relay unit 28, the time information of these records is recorded by the relay unit 28. The time information of the record related to the device data can be corrected to the time information given by the first system controller, and later recorded by the first system controller 14 and the relay unit 28 It becomes possible to merge records.

  In the system according to the present embodiment, the first system controller 14 and a device other than the relay unit 28 connected thereto, or the relay unit 28 and a device other than the first system controller 14 connected thereto. Even if a communication error occurs due to disconnection or the like, the device data can be recorded in each device so that the device data can be merged later.

An overall configuration diagram of an endoscopic surgery system to which the medical information collecting apparatus according to the present embodiment is applied, and a block diagram showing the main configuration thereof are the same as those shown in FIGS. 1 and 2.
The block diagram relating to the main configuration of the first system controller 14 is almost the same as that shown in FIG. 3, but in this embodiment, the first system controller 14 further monitors the memory capacity. It also has a memory monitoring unit that performs caution / warning notification as necessary.

  FIG. 8 is a flowchart showing an example of the memory monitoring operation performed by the first system controller 14 in this embodiment, and is started when, for example, the controller 14 is powered on.

  As shown in the figure, the first system controller 14 first checks the connection state of the device connected to the connector 42 by the communication I / F 43 (S31), and then the first memory 44 and The memory I / F (not shown), the memory I / F 41, and the network I / F 46 of the second memory 45 are checked (S32), and the check results are notified (S33). This notification is performed, for example, by displaying the check result on the display panel 12.

  Subsequently, when device data to be recorded as a log is generated (S34), the free memory capacity of the second memory 45 and the third external memory 38 attached is checked (S35), and the second memory 45 is checked. If the free memory capacity of the second memory 45 is greater than or equal to the first predetermined capacity, or the free memory capacity of the second memory 45 is less than the first predetermined capacity and the third external memory 38 When the free memory capacity is equal to or greater than the second predetermined capacity, a record relating to the device data is recorded as a log in the third external memory 38 (S36).

  On the other hand, when the free memory capacity of the second memory 45 is less than the first predetermined capacity and the free memory capacity of the third external memory 38 is less than the second predetermined capacity, The free memory capacity of the recording medium possessed by the server 37 on the hospital network is checked (S37). If the free memory capacity of the recording medium possessed by the server 37 is equal to or larger than the third predetermined capacity, the recording possessed by the server 37 is performed. A record relating to the device data is recorded on the medium as a log (S36), and if it is less than the third predetermined capacity, an error notification serving as a caution / warning that the free memory capacity is insufficient is provided. Perform (S38). This notification is also made by displaying on the display panel 12, for example.

  In this memory monitoring operation, when the free memory capacity of the second memory 45 is less than the first predetermined capacity, a warning / warning that the free memory capacity of the second memory 45 is insufficient. It is also possible to make an error notification. In addition, when the free memory capacity of the third external memory 38 is less than the second predetermined capacity, an error notification serving as a caution / warning that the free memory capacity of the third external memory 38 is insufficient is provided. It is also possible to do so. Alternatively, the available memory capacity is insufficient when the available recording capacity of one or more recording media of the second memory 45, the third external memory 38, or the server 37 is less than a certain level. It is also possible to make an error notification that is a warning / warning to the effect.

  In this memory monitoring operation, when the device data is stored in the second memory 45 as a log, if the log stored in the past remains in the second memory 45, the device data is stored in the second memory 45. Before storing as a log, a part or all of the log stored in the second memory 45 may be transferred to a recording medium of the third external memory 38 or the server 37 on the hospital network. Is possible.

  As described above, according to the present embodiment, when the free memory capacity of the memory in which the log is recorded decreases, an error notification to that effect is given. By responding by transferring it to the memory, it is possible to prevent the device data from being recorded as a log because there is no free memory capacity.
