The controller 24 generates a display signal based on the supplied error signal based on the identification of the error content and the identification number of the board in which the error has occurred, and outputs the display signal to the output controller 23. The output controller 23 controls the drive of the centralized display panel 21 based on the display signal supplied from the control controller 24, and displays the identification number of the board in which the error has occurred and the identification of the error.

Such a conduction detection control controller 25
And an error information detection function including an abnormal signal detection controller 26 is disposed in each of the medical devices 17a to 17d. That is, the drive of each of the medical devices 17a to 17d is controlled by the system controller 19 based on an input instruction from the central control panel 22 and output from each of the medical devices 17a to 17d. The information of the driving operation state to be performed is displayed on the central display panel 21 via the system controller 19 by the medical devices 17a to 17d.
The driving operation state is displayed every time.

On the other hand, when an error occurs in the medical devices 17a to 17d, for example, when the conduction detection controller 25 of the medical device 17a detects that there is an abnormality in the drive potential of the drive circuit of the board on which the medical device 17a is located, The potential error signal is output to the control controller 24 of the medical device 17a.

Thus, the operator of the medical devices 17a to 17d can constantly monitor the driving operation state of the medical device by displaying the centralized display panel 21, and if the driving operation of the medical device is abnormal, Occurs, it is possible to identify not only the medical device in which the abnormality has occurred, but also to identify the board in the medical device in which the abnormality has occurred, and transmit the information indicating the abnormality to the manufacturer 14 via the communication line 16 for transmission. By doing so, the maintenance service can be promptly requested to the maker 14, and the maker 14 can quickly identify the location where the abnormality has occurred and prepare for repairing the abnormality. Next, the operation from the abnormality detection of the medical device to the request for the maintenance service to the manufacturer 14 will be described with reference to FIG.

The medical device system 13 is installed at a predetermined treatment place in the hospital 12, the drive power of the medical device is turned on (step S11), and the instruction input for drive control of each of the medical devices 17a to 17d is sent to the central control panel 22. The medical devices 17a to 17d are driven and driven on the basis of the input command, and the driving operation state is displayed on the central display panel 21, and the usage state of the medical device where the medical treatment is performed ( Step S12) is assumed. When the medical device is used in step S12, the conduction detection controller 25 constantly performs conduction detection (step S13) for detecting an abnormal drive potential of a drive circuit of a board built in the medical devices 17a to 17d. On the other hand, the medical devices 17a-1
Abnormal signal detection (step S14) for detecting an abnormality in the processing signal of the drive circuit of the board built in 7d is always executed.

When an abnormality is detected in either of the steps S13 and S14, the controller controller 24 identifies the continuity error or the abnormal signal, which is the content of the error, and the error display information indicating the board on which the error has occurred. Is generated (step S16), this error display information is converted and generated into an error display signal by the output controller 23 (step S16), and is supplied to the centralized display panel 21. An error occurrence display of 17a to 17d, an error occurrence content, and an error occurrence board identification display are performed (step S17).

The central display panel 21 in step S17
The operator or the medical device operator selects and inputs a "support service" button (not shown) provided on the centralized control panel 22 based on the abnormality display (step S1).
8), the medical device system 13 is connected to the support computer 15 of the maker 14 via the communication line 16 and transmits and transmits identification information such as the name of the hospital where the abnormality has occurred, the medical device and the board, and the details of the abnormality.

Based on the abnormality information transmitted and transmitted from the hospital 12 in step S18, the manufacturer 14 proceeds to step S18.
At 19, a reply to the hospital 13 is returned to the hospital 13 with the reception of the abnormality information and the reception of the support, and the support request to the manufacturer of the hospital 12 is completed (step S20), and the manufacturer 14 performs In addition to procuring various parts and arranging service personnel required for performing the repair service, the repair service is estimated and notified to the hospital 12 (step S21).

As described above, in the second embodiment, for each board provided with a control drive circuit for each medical device provided in the medical device system, whether the drive control state is a predetermined operation state or an abnormal operation state is determined. Since the detection and the display are performed on the display panel, the operator and the operator can grasp the driving operation state during use of the medical device, and can execute the treatment with confidence.

If an abnormal condition occurs in the medical device, the medical device in which the abnormal condition has occurred and the contents of the abnormality are displayed on the display panel, so that only the medical device in which the abnormal condition has occurred is displayed. By exchanging the medical device, the medical treatment can be continued, and for the medical device in an abnormal state, it is possible to immediately notify the manufacturer of the occurrence of the abnormality via a communication line and promptly request a repair service. On the other hand, the manufacturer estimates the cause of the abnormality and identifies the parts required for the repair service based on the medical device in the abnormal state transmitted along with the repair service request from the hospital, the content of the abnormality, and the identification information of the abnormality occurrence board. Arrangement and estimation of repair service time and the like can be performed, and prompt repair service is executed.

Accordingly, by providing a self-diagnosis function on each function board built in the medical device and connecting the medical device and a repair service source of the medical device using a communication line, abnormalities in the medical device can be obtained. When an error occurs, the details of the error are displayed on the display panel, enabling quick response to abnormal operation of the medical device, and transmitting the error occurrence information to the repair service source via a communication line. By doing so, it is possible to estimate the cause of the abnormality, and it is possible to quickly respond to the repair service.

Next, referring to FIG. 8 and FIG.
An embodiment will be described. FIG. 8 shows a configuration of the medical device support system of the third embodiment, and FIG. 9 shows a flowchart of an operation of remotely rewriting a program. The medical device support system of the present embodiment has the same configuration as that shown in FIG. 1, and the configuration of the medical device support system of FIG. 2 has the configuration shown in FIG.

The medical device support system 41 shown in FIG. 8A has a configuration in which a medical device 2 having a communication function and a remote control computer 4 are connected by a communication line 5 for transmitting information. This medical device support system 4
1 includes a plurality of program means for storing a program of the medical device 2, and in FIG.
1 and 6-2.

The medical device 2 has a CP connected to a communication interface 7 and two ROMs 6-1 and 6-2.
U42, and the CPU 42 has ROMs 6-1 and 6-
In accordance with the program 2, the operation of the medical device 2 is controlled, and the ROMs 6-1 and 6 are controlled under the control of the CPU 42.
-2 program rewriting is performed. The ROM 6-1 and the ROM 6-2 are configured by, for example, a nonvolatile (electrically rewritable) EEPROM (or flash memory).

The remote operation computer 4 has a CPU 43 connected to an interface 9 for communication via the communication line 5 and a program storage means (hard disk) 11 in which rewrite program data is stored. Control operation of program transmission for program rewriting is performed. The hard disk 11 also stores an operation program for the CPU 43.

In this embodiment, at least two storage means are provided as storage means for storing the program data to be transmitted, so that the program can be more reliably rewritten even when the transmission state of the communication line 5 is not good. I can do it.

In the first embodiment, the medical equipment 2 of the hospital 1
A program for rewriting / updating the program and the remote control computer 4 of the manufacturer 3 is transmitted via the communication line 5 so that the program in the ROM 6 can be rewritten / updated. Quality may be reduced.

Therefore, in the present embodiment, the plurality of ROMs 6-1 and 6-2 are prepared as described above, so that the program can be rewritten / updated more reliably.

More specifically, as described with reference to FIG. 9, one of the plurality of ROMs 6-1 or 6-2 is rewritten according to whether the received data (program rewrite data) is an odd number or an even number. As a result, if the rewriting is not performed normally in the first time (for example, the odd numbered time), the other data in the plurality of ROMs 6-1 or 6-2 is rewritten in the next reception (for example, the even numbered time). To do. As a program storage means built in the medical device 2, instead of the ROMs 6-1 and 6-2 of FIG.
As shown in (B), two hard disks 44-1, 4
4-2 may be adopted.

Next, the operation of rewriting a program will be described with reference to FIG. When the medical device 2 and the remote operation computer 4 are connected via the communication line 5, the operation state is established, and as shown in step S 31, the data of the rewriting program stored in the hard disk 11 is transmitted from the remote operation computer 4 to the hard disk 11. It is transmitted to the CPU 42 of the medical device 2 under the control of the CPU 43.

Then, the CPU 42 proceeds to the next step S32.
And the parameter m of the number of transmissions is an integer (n) times 2 (m =
2n) That is, it is determined whether or not it is an even number. In the case of the first transmission, m = 1, so the flow proceeds to step S33. In the case of the next transmission (m = 2), the flow proceeds to step S35.

In step S33, the CPU 42 reads the first data (specifically, the ROM) based on the received data.
The program data of 6-1 is rewritten. And
In the next step S34, the CPU 42 determines whether or not the rewriting has been completed. If it is determined that the rewriting has been completed normally, the CPU 42 ends this operation. If it is determined that the rewriting has not been completed normally, as shown in step S36, m is incremented by one (in this case, m = 2), and because the program could not be normally rewritten to the CPU 43 of the remote operation computer 4, information for retransmitting the program was transmitted. Return.

If it is determined at step S32 whether the number is an even number or not, the process proceeds to step S35, and the CPU 42 executes the program of the ROM 6-2 (specifically, the ROM 6-2) based on the received data. Rewrite data. Then, in the next step S34, the CPU
42 determines whether the rewriting has been completed. If the rewriting has been completed normally, this operation is terminated. If it is determined that the rewriting has not been completed normally, m is incremented by one (step S36), and CPU 43 of computer 4
Since the program could not be rewritten normally, information for transmitting the program is transmitted again, and the process returns to step S31.

By doing so, even when the transmission state of the communication line 5 is not good, the program rewriting data can be repeatedly transmitted until the program can be rewritten normally, so that the program rewriting can be performed more reliably. There is.

9 is described with reference to the case of FIG. 8A, but instead of the ROMs 6-1 and 6-2 as shown in FIG. 8B, two hard disks 44-1 and 44-2 are used. Is adopted, the ROM 6-1 may be replaced with the hard disk 44-1 and the ROM 6-2 may be replaced with the hard disk 44-2 in the description of FIG.

The above program rewriting (updating)
Alternatively, only one ROM (for example, 6-1) or a hard disk (for example, 44-1) may be rewritten (updated). When the program is rewritten (updated) by the next version upgrade or the like, the other R
OM (for example, 6-2) or a hard disk (for example, 44
Only -2) may be rewritten (updated).

6d and the like, and as a minimum necessary function at the time of standby, it has a function of monitoring a medical device 46a and a function of centrally controlling a medical device 46c.

The normal program stored in the ROM 6-1 corresponds to the function during normal operation. In this embodiment, normally, only the ROM 6-1 is rewritten by the received program data, and if the rewriting is not performed normally, the fixed program stored in the ROM 6-2 is used. It works.

Next, the operation of this embodiment will be described with reference to FIG. When the medical device 2 and the remote operation computer 4 are connected via the communication line 5, the operation state is activated, and as shown in step S 41, the data of the rewriting program stored in the hard disk 11 is transmitted from the remote operation computer 4 to the hard disk 11. It is transmitted to the CPU 42 of the medical device 2 under the control of the CPU 43.

In the next step S42, the CPU 42 rewrites the normal program using the received data, specifically rewrites the program in the ROM 6-1. Then, in the next step S43, it is determined whether or not the rewriting has been completed normally, and if the rewriting has been performed normally, this operation is terminated. -2 is set to a state for activating the fixed or emergency program stored in the medical device 4 (that is, when the medical device 4 is turned on, the
The program 42 is set to the operating state by the program -1, but after step 44, the CPU 42 switches to the state of reading the fixed program in the ROM 6-2), and the operation in FIG. 12 ends.

According to the present embodiment, even if the program cannot be normally rewritten by remote transmission, the program can be operated with the fixed program. Can be.

Although the ROM 6-2 is not remotely rewritten, the ROM 6-2 may be replaced with a new one as necessary to open the lid of the medical device 2 so that the version can be upgraded.

In 1, a medical device system 52 and a remote operation computer 4 are connected by a communication line 5. The medical device system 52 has a plurality of medical devices 2A, 2B, 2C and a system controller 54 for centrally controlling the plurality of medical devices 2A, 2B, 2C, and the system controller 54 is remotely operated via the communication line 5. Computer 4.

FIG. 14 shows an example of the internal configuration in FIG. The hard disk 11 in the remote control computer 4
Under the control of the CPU 43, the rewriting program data stored in the first area 11a is transmitted from the interface 9 to the system controller 54 of the medical device system 52 via the communication line 5.

The CPU 43 receives the program data returned from the system controller 54, stores the program data in the second area 11b of the hard disk 11, and stores the program data for rewriting stored in the first area 11a and the second area 11b. The stored returned program data is read out, and the matching register 43a in the CPU 43 is read out.
Can be used to check whether they match.

The system controller 54 controls the transmission / reception of the interface 61 of the communication line 5, the interface 62 for transmitting / receiving with a cable connected to the medical device 2A and the like, the remote control computer 4, and the like. And a hard disk (or a memory such as a RAM) 64 as a storage means for temporarily storing an operation program of the CPU 63, program data to be transmitted / received, and the like. .

The medical device 2A has the same configuration as that shown in FIG. 8A, for example, and has two ROMs 6-1 and 6-2. Other medical devices 2B and the like have the same configuration.

In the present embodiment, as will be described with reference to FIG. 15, program data transmitted from the remote control computer 4 is received, and one of a plurality of storage means such as the medical device 2A is rewritten. Then, the rewritten program data is returned to the remote operation computer 4, and the CPU 43 of the remote operation computer 4 checks whether or not the returned data matches the transmitted data. Is retransmitted.

If they match, the program data is started using the program data to determine whether the program is normal. If the program data is normal, the program data is set to be started using the program data. Is rewritten (copied). If it is determined that the data is not normal, it is set to be activated by the program data of the other storage means.

Next, the operation of this embodiment will be described with reference to FIG. The power is turned on and the operation starts. In step S51, the rewriting program data is transmitted from the CPU 43 of the remote control computer 4 to the system controller 54 of the medical device system 52 via the communication line 5. In this case, the CPU 43 performs the rewriting of the medical device 2.
Information specifying I (I = A, B, C) is attached and transmitted.

When the system controller 54 needs to upgrade the software of the medical device 2I to the remote control computer 4, the system controller 54 sends a signal requesting the remote control computer 4 to upgrade the software of the medical device 2I. And the remote control computer 4 may transmit the program to the system controller 54.

As shown in step S52, the CPU 63 of the system controller 54 temporarily stores the received data in the hard disk 64, transfers the data to the medical device 2I for rewriting with an appropriate amount of data, and sends a rewriting signal to the medical device 2I. The device 2I (CPU 42) is a medical device 2I
The first program of one of the two ROMs 6-1 and 6-2 (for example, 6-1) is rewritten.

After rewriting, the CPU 43 returns the data of the first program to the remote control computer 4 via the system controller 54 as shown in step S53.

As shown in step S54, the CPU 43 of the remote operation computer 4 stores the returned data in the second area 11b of the hard disk 11, and stores the (first program) data stored in the second area 11b in the first area.
Whether or not the data matches the rewrite program data stored in the area 11a is compared (compared) using the comparison register 43a.

If there is a mismatch as a result of the comparison, the process returns to step S51, and the processes of steps S51 to S54 are repeated. If it is determined that they match, the matching signal is sent to the system controller 54.
Send to the side.

Then, as shown in step S55, the CPU 42 of the medical device 2I determines whether or not the first program is normal (for example, a state where the medical device 2I is reset and temporarily activated by the first program). Set to
Judge whether it works normally).

If it is determined that the operation is normal, step S
As shown in 56, the state is set to be activated by the first program, and the routine goes to the next step S57. On the other hand, if it is determined that the data is not normal, as shown in step S58, a state is set in which the program is started by the second program (before rewriting) written in the other ROM 6-2 that has not been rewritten, and the process proceeds to step S57. Move on.

In step S57, it is determined whether the program to be started has been copied. If the data has been copied, the rewriting operation is terminated. If the data has not been copied, the program data in the two ROMs 6-1 and 6-2 are started if the data has not been copied, as shown in step S59. The CPU 42 performs a process of copying from one to the other so as to become the program data, and ends this operation.

Specifically, at step 59, the ROM 6
-1 is set to the activated state, the program is copied to the ROM 6-2. Conversely, if the program stored in the ROM 6-2 is set to the activated state, the program is copied to the ROM 6-2. Copied to 1. Then, the programs stored in both the ROMs 6-1 and 6-2 are brought into a state where they can be started normally.

According to the present embodiment, the program data after being transmitted and actually rewritten is returned to the transmission source, and it is determined whether or not the program data matches the transmitted data.
If they do not match, the transmission is repeated, so that the program data to be transmitted can be reliably rewritten.

Also, it is determined whether the rewritten program is normal or not. If it is determined that the rewritten program is not normal, the program is started with the unrewritten program before rewriting. Even in the case where the rewriting program has a new failure or the like and cannot be operated normally, the rewriting program can be operated with the program that has not been rewritten.

In this case, it has been found that there is a fault to be improved in the program that has not been rewritten, and an attempt has been made to upgrade the program by transmitting the program in order to eliminate the fault. If there is a new fault and it is determined that it is not normal, it will be operated with the old program before rewriting, but the fault in that case is known in detail,
Although functions and the like are limited so as not to be affected by the failure, operation can be reliably performed in the limited state.

Further, since the plurality of ROMs 6-1 and 6-2 are set to the normally operating programs before the end of the rewriting operation of the program, the ROMs 6-1 and 6-2 are reliably operated for the rewriting operation of the next program. We can maintain state.

Next, a sixth embodiment of the present invention will be described with reference to FIG. In this embodiment, for example, in the apparatus shown in FIG. 8A, the medical device 2 performs rewriting by adding a self-diagnosis program to the rewriting program data from the remote operation computer 4 and transmitting the self-diagnosis program to the medical device 2. The self-diagnosis of the medical device is performed before.

The operation will be described with reference to the flowchart of FIG. As shown in FIG. 16, the power is turned on to be in an operation state, and as shown in step S61, the remote control computer 4 transmits to the medical device 2 rewrite program data to which the self-diagnosis program data is added to the medical device 2 as shown in step S61. As shown, when the medical device 2 receives the program data, first, before rewriting,
The CPU 42 of the medical device 2 performs a self-diagnosis of hardware of each unit of the medical device 2. As a result of the self-diagnosis of the hardware, if it is diagnosed as NG or abnormal, as shown in step S68, an error or the like is reported (notified) to the remote operation computer 4, and the process ends.

On the other hand, if it is diagnosed as normal or OK, the self-diagnosis of the received program is performed as shown in step S63. If the diagnosis result indicates that the operation is NG or the like, an abnormality is reported (notified) to the remote operation computer 4 as shown in step S68.

On the other hand, if it is determined that the program is normal or OK, one ROM (for example, 6-1) is rewritten with the received program data as shown in step S64 (in FIG. 16, the first program rewrite is abbreviated). ). After the rewriting, the self-diagnosis of the program is performed again as shown in step S65.

If it is determined that the rewriting operation is normal or OK, the rewriting operation is completed by setting the state to be activated by the first program as shown in step S66.
Conversely, if it is diagnosed as NG or the like, the state is set to a state in which the second program (old program) written in the other ROM 6-2 is started, and this operation ends.

According to the present embodiment, when a program is received and rewritten, the self-diagnosis of the hardware and the self-diagnosis of the received program are performed before rewriting, and the self-diagnosis of the program is performed even after rewriting. Since the diagnosis is performed, whether the medical device 2 operates can be more reliably diagnosed.

Further, if the self-diagnosis of the rewritten program is diagnosed as NG, the program is set to be started by the program of the ROM that has not been rewritten. Can also operate normally.

In the present embodiment, the medical device 2I performs a self-diagnosis when receiving the rewriting program. However, the present invention is not limited to this. If the diagnosis is normal,
The received program may overwrite (rewrite). Note that embodiments and the like configured by partially replacing or combining the above-described embodiments and the like also belong to the present invention.

By the way, as shown in FIG.
In the case of a device or a system in which the device 71B and the device 71B are connected by a cable 72, it may be possible to determine whether or not the cable 72 is disconnected. In this case, (A) a cable check mode may be provided separately from the normal operation mode.

In the device 71A, both ends of an impedance element Z1 connected in series to an output terminal via a (transmission) buffer are turned on / off by a switch SW1, and are connected to two cables 71, respectively. Between the output terminals, an impedance element Z2 can be turned ON / OFF by SW2.

The impedance elements Z1 and Z2 are connected to the device 71.
The impedance value of the input terminal when the device 71B is viewed from the output terminal of A (the correct value when there is no disconnection) is a value that cannot be ignored. A buffer (for reception) is also provided at the input end of the device B. In cable check mode, open switch SW1 and switch S
Close W2. The voltage of TP1 at this time is detected. The voltage of TP1 shows a different value depending on whether the cable 72 is disconnected or not.
The presence or absence of disconnection can be understood.

(B) Means for switching between the above two modes may be provided by a communication line (whether wired or wireless) from a remote location. In this case, optical switches are used for the switches SW1 and SW2. As described above, by providing the cable check mode, the normal operation is not hindered.
A detecting means can be formed, and it can be determined whether or not the cable is disconnected.
