Hereinafter, the operation and the like of the medical device management system 1 will be described with reference to the flowcharts of FIGS. 5 to 9, and the configurations and the like of FIGS.

As described above, the management server 50 shown in FIG. 1 is communicable with the medical device 10a in the hospital via the Internet 2, and the management server 50 monitors the medical device 10a etc. every 24 hours. To do.
Specifically, as shown in ST1 of FIG. 5, it is determined whether or not 24 hours have elapsed since the previous access to the medical device 10a or the like. That is, the periodic check operation execution unit (program) 56 in FIG. 3 refers to information stored in the periodic check time information storage unit 60 in FIG. 4, for example, 24 hours, and the clock unit 55 in FIG. Referring to the above, it is determined that 24 hours have elapsed.

  If it is determined in ST1 that 24 hours have elapsed, the process proceeds to ST2. In ST2, the management server 50 requests the medical device 10a and the like to transmit the device information and operation history information of the medical device 10a and the like.

In ST3, the medical device 10a or the like that has received the request of ST2 transmits device information and operation history information in response to the request. Specifically, the medical device 10a and the like are the device number, device type, model name, date of sale, hospital ID, repair person number, software version, etc. stored in the device information storage unit 15 of FIG. Send device information of.
Further, the medical device 10a or the like transmits operation history information such as the temperature and the number of uses stored in the operation history information storage unit 16 of FIG.
Note that once the management information is received by the management server 50, the information is not changed thereafter, so that the device information is not received thereafter, and only the operation history information is received.

Next, the process proceeds to ST4. In ST4, the management server 50 stores the device information received from the medical device 10a or the like in the device information table storage unit 61 of FIG. 4, and stores the operation history information received from the medical device 10a or the like in the operation history information table of FIG. Stored in the unit 62.
FIG. 10 is a data example showing the device information table 61 a stored in the device information table storage unit 61.
As shown in FIG. 10, the device information table 61a includes, for example, a device number. (Device information), device type, device name, date of sale, hospital ID, repair person No. (Information), software version, and the like are stored.
The device information table storage unit 61 and the operation history information table storage unit 62 are examples of the medical device information storage unit.

Next, the process proceeds to ST5. In ST5, the failure determination unit (program) 57 of the management server 50 in FIG. 3 operates and refers to, for example, “device format” data, which is the type information of the medical device in the device information table 61a in FIG. In the case of FIG. 10, the device format is “ABC”.
Next, in ST5, the failure determination unit (program) 57 refers to, for example, the failure determination criterion table storage unit 63 of FIG. As shown in FIG. 11, the failure determination criterion table storage unit 63 stores, for example, a failure determination criterion table 63a which is failure determination criterion information.
FIG. 11 is a data example showing the failure determination reference table 63a.
Specifically, information for determining a failure for each device type is stored. For example, when the device type is “ABC”, the determination item is “temperature”, the failure determination value is 5 ° C., and the determination method is “below”.
Therefore, in this example, when the device type is “ABC”, it is determined whether or not there is a failure in the medical device 10a or the like depending on whether the temperature is 5 ° C. or less.
As described above, the information in the failure determination criterion table 63a is associated with “device type” information such as the medical device 10a.

  Therefore, in ST5, first, the failure determination unit (program) 57 searches the data in the same device format as the “device format” in FIG. 10 from FIG. 11, and determines the determination item in that case, “temperature” in the above example. get.

  Next, the process proceeds to ST6. In ST6, the failure determination unit (program) 57 stores information corresponding to “temperature” which is the determination item acquired in ST5, that is, “temperature” information in the operation history information table 62 of the operation history information table storage unit 62 of FIG. The failure determination value and the determination method are acquired from the failure determination reference table 63a of FIG.

  Next, the process proceeds to ST7. In ST7, it is determined whether the “temperature” information of the operation history information of the medical device 10a or the like is the failure determination value and determination method of FIG. 11, for example, “5 ° C. or less”.

  If it is determined in ST7 that “5 ° C. or less”, the medical device 10a or the like is determined to be out of order. As described above, in the present embodiment, there are different failure determination items depending on the type of the medical device 10a and the like, and the presence or absence of the failure is determined based on the determination item. Detailed failure determination can be made, and safe use of the medical device 10a and the like can be ensured.

On the other hand, if it is determined in ST7 that the medical device 10a or the like is not in failure, a “maintenance determination step” is performed as shown in FIG. 5 in order to determine whether maintenance is necessary.
This “maintenance determination step” will be described later.

  If it is determined in ST7 that the medical device 10a or the like is out of order, the process proceeds to ST8 and the subsequent steps. In ST8 and subsequent steps, the degree of urgency of failure of the medical device 10a and the like is determined.

First, in ST8, a specific degree of failure of the medical device 10a or the like is determined. Specifically, the failure determination unit (program) 57 operates and refers to the “failure priority coefficient” that is specific abnormality degree information in the device format of the failure determination reference table 63a in FIG. In the example of FIG. 11, for example, “2” is stored in the failure priority coefficient information storage unit of FIG.
Thereby, the priority of the failure in the failure determination result of the failure of the medical device 10a or the like, in the above example, the “temperature” abnormality in the device type “ABC” is specified.

Next, the process proceeds to ST9. In ST9, the failure determination unit (program) 57 operates and refers to the device format reference priority coefficient table storage unit 65 in FIG. 4 to acquire, for example, device priority coefficient, which is device type abnormality degree information. That is, the device format reference priority table storage unit 65 of FIG. 4 stores the device format reference priority coefficient table 65a shown in FIG. 12, and in this table, the device-specific priority corresponding to the device format is stored. The degree factor is shown.
For example, when the medical device 10a or the like is extremely important for treatment like an oxygenator, the device priority coefficient is relatively high. On the other hand, when the medical device 10a or the like is a blood glucose level measuring device or the like, it is set relatively low. Has been.
Therefore, the urgency level of the failed medical device 10a and the like can be determined based on the device priority coefficient.
FIG. 12 is a data example showing the device format reference priority coefficient table 65a.

  In the above example, since the device format is “ABC”, the device format reference priority coefficient table 65a in FIG. 12 is referred to, the device priority coefficient “2” is obtained, and the device format reference priority in FIG. Stored in the coefficient information storage unit 66.

  Next, the process proceeds to ST10. In ST10, the failure determination unit (program) 57 operates to acquire the information on “sales date” in the device information table in FIG. 10 and the information on “date” in the clock unit 55 in FIG. The difference is obtained, “use period data” of the medical device 10a or the like is calculated, and the result is stored in the use period data storage unit 67 of FIG.

Next, the process proceeds to ST11. In ST11, the failure determination unit (program) 57 operates and refers to the device usage history reference priority coefficient table storage unit 68 of FIG. In the device usage history reference priority coefficient table storage unit 68, for example, a device usage history reference priority coefficient table 68a is stored.
As shown in FIG. 13, the device usage history reference priority coefficient table 68a shows usage history reference priority coefficients, which are device usage history abnormality degree information according to the usage period of the medical device 10a and the like. The configuration is such that the urgency level of failure response corresponding to the usage period of the medical device 10a and the like can be easily determined.
Therefore, the failure determination unit (program) 57 applies the data in the usage period data storage unit 67 of FIG. 4 to the device usage history reference priority coefficient table 68a, so that the usage history reference priority in the medical device 10a and the like can be easily obtained. The degree coefficient can be obtained.
FIG. 13 is a data example showing the device usage history reference priority coefficient table 68a.
In ST11, the usage history reference priority coefficient obtained in this way is stored in the device usage history reference priority coefficient information storage unit 69 of FIG.

As a result, the medical device management system 1 acquires three indicators as the urgency level for failure handling of the target medical device 10a and the like. That is, information on the degree of urgency of failure handling in the determination items such as the temperature of the medical device 10a (failure priority coefficient information), information on the degree of urgency of failure handling according to the device type of the medical device 10a, etc. (The device type reference priority coefficient information) and the degree information (the device usage history reference priority coefficient information) such as the urgency level of failure handling according to the usage period of the medical device 10a and the like.
Therefore, in the present embodiment, these three indexes are integrated to calculate an index such as the final emergency level of failure handling.

  Specifically, in ST12, the failure determination unit (program) 57 performs the failure priority coefficient information storage unit 64, the device format reference priority coefficient information storage unit 66, and the device usage history reference priority coefficient information storage unit. 69 is referred to, and these are integrated (for example, each coefficient is added to obtain a numerical value such as “6”) to create the general priority coefficient information (for example, “6”), 4 in the general priority coefficient information storage unit 70.

Next, the process proceeds to ST13. In ST13, the failure determination unit (program) 57 refers to the general priority coefficient information storage unit 70 and the general priority rank determination table storage unit 71 of FIG.
In the general priority rank determination table storage unit 71, as shown in FIG. 14, for example, the general priority indicating the general priority rank information is the general abnormality degree information (abnormality degree information) corresponding to the general priority coefficient information. A degree rank determination table 71a is stored. This general priority rank information is shown in three levels, for example, “high, medium, low”.
Therefore, the failure determination unit (program) 57 can easily apply the numerical value in the general priority coefficient information storage unit 70 of FIG. 4, for example, “6” to the general priority rank determination table 71a of FIG. It is possible to grasp the overall priority rank. In the above example, since the numerical value is “6”, the overall priority rank is “high”.
FIG. 14 is a data example showing the general priority rank determination table 71a.

In ST13, the general priority rank information obtained in this way is stored in the general priority rank information storage unit 72 of FIG.
As a result, it is possible to acquire an index such as the final emergency level of failure handling that integrates the above three indexes as the emergency level of failure handling of the target medical device 10a and the like.

Next, the process proceeds to ST14. In ST14, the failure determination unit (program) 57 stores the above determination result in, for example, the determination result table storage unit 73, which is the result information storage unit in FIG.
FIG. 15 is a data example showing the determination result table 73 a in the determination result table storage unit 73. As shown in FIG. 15, the “equipment No.”, “determination item”, “determination result”, “determination date”, and “priority rank” are stored in the determination result table 73a.

  Next, the process proceeds to ST15. In ST15, the failure determination unit (program) 57 refers to the determination result table 73a (see FIG. 15) in the determination result table storage unit 73 of FIG. In “Device No.”, it is checked whether or not there is the latest data whose “judgment result” is “failure”.

If such data exists in ST16, the process proceeds to ST17, where the failure determination unit (program) 57 compares the “determination date” of the latest determination result table 73a with the current “determination date”, and the difference To obtain the period data.
Then, the process proceeds to ST18, and it is determined whether the period is within a predetermined period, for example, within 7 days. If it is over 7 days, the process proceeds to ST19.

In ST19, the failure determination unit (program) 57 operates and refers to the “repair person No.” in the device information table 61a in FIG. 10 and the repair person table 74a in the repair person table storage part 74 in FIG. Obtain contact information such as the email address of the person in charge of repair.
The information such as the device type, device name, hospital name, judgment item, and overall priority rank is abnormality information. For example, as the failure information, the repair person PC 3 and / or the repair person mobile phone 4 in FIG. Send to.
FIG. 16 is a data example showing the repair person table 74a.

Therefore, the person in charge of repair who has received such failure information can immediately grasp not only the presence / absence of failure of the target medical device 10a but also the urgency level of the failure, etc., and can take prompt action.
Further, in the present embodiment, there is the latest data having the same “device No.” as the target medical device 10a and the like determined this time, and the “judgment result” being “failure”, and the judgment date of the data is the same. In the case of less than 7 days, the person in charge of the repair is not notified.
Therefore, it is possible to prevent confusion of the person in charge of repair because there is no need to repeatedly notify the redundant failure information.

  By the way, when it is determined in FIG. 7 that the target medical device 10a or the like is not a failure, the present embodiment determines whether or not the medical device 10a or the like needs to be maintained. This maintenance necessity determination process will be described with reference to FIGS.

First, as shown in ST31 of FIG. 8, the maintenance judgment unit (program) 58 of FIG. 3 operates, and the maintenance judgment standard shown in FIG. 17 is maintenance judgment standard information in the maintenance judgment standard table storage unit 75 of FIG. Referring to the table 75a, the operation history information (for example, “temperature”) (operation history information table storage unit 62 in FIG. 4) corresponding to the determination item (for example, temperature) is acquired, and the maintenance necessity determination value (in FIG. For example, refer to 10 ° C.) and a determination method (for example, the following).
FIG. 17 is a data example showing the maintenance judgment reference table 75a.

  In ST32, for example, it is determined whether “temperature” as one of the determination items (parameters), which is the operation history information, is “10 ° C. or less”. In the following cases, it is determined that maintenance is necessary.

  Next, the process proceeds to ST33. In ST33, the maintenance determination unit (program) 58 operates to obtain the “maintenance priority coefficient” data in the maintenance determination reference table 75a of FIG. 17 and store it in the maintenance priority coefficient information storage unit 76 of FIG.

Hereinafter, the contents of ST34 to ST36 are the same as those of ST9 to ST11 described above, and similarly, “the device type reference priority coefficient” and “the device usage history reference priority coefficient” are obtained.
In ST37, the overall priority coefficient information is generated based on “the maintenance priority coefficient information”, “the apparatus type reference priority coefficient”, and “the apparatus usage history reference priority coefficient”.

  In ST38 to ST44, processing is performed in the same manner as in ST13 to ST19 described above, and the “maintenance necessity information” is informed to the repair person together with the “overall priority rank” that is a priority index of the necessity for maintenance. Will be.

  Accordingly, in the present embodiment, not only the failure information but also the maintenance necessity information is notified to the repair person together with the priority index of the maintenance necessity, so that the safe use of the medical device 10a or the like is more reliably performed.
