In a Holter electrocardiograph such as that disclosed in Patent Document 1, a memory card storing an electrocardiogram waveform and personal information of a person whose electrocardiogram waveform was measured are sent to an analysis operator. That is, the personal information of the person to be measured is transmitted to the analysis business that owns the server for analysis. However, the analysis provider can perform the analysis as long as there is an electrocardiogram waveform, and the subject's personal information is unnecessary for the analysis. There is a problem that exchanging personal information even though it is not necessary for analysis poses a risk of leakage of personal information.

This specification discloses a technique for improving the anonymity of the subject of electrocardiogram waveforms in electrocardiogram waveform analysis.

The electrocardiogram waveform analysis system disclosed in this specification includes a Holter electrocardiograph that measures the electrocardiogram waveform of a living body, and a management device that analyzes the electrocardiogram waveform. A Holter electrocardiograph includes a body that can be carried by a living body, an electrocardiogram waveform storage section, an identification information storage section, and a storage medium. The electrocardiogram waveform storage unit is provided inseparably from the main body, and stores electrocardiogram waveforms measured from a living body. The identification information storage unit is provided inseparably from the main body and stores identification information for identifying the Holter electrocardiograph.

The storage medium can be stored separately from the main body when the Holter electrocardiograph is carried by a subject to measure the subject's electrocardiogram waveform. The management device has an input unit for inputting an electrocardiogram waveform and identification information. The input unit acquires the electrocardiogram waveform stored in the electrocardiogram waveform storage unit and the identification information stored in the identification information storage unit when the main body is connected to the management device by wire or short-range wireless communication. The management device includes a first storage unit that associates and stores the electrocardiogram waveform and the identification information that are input from the input unit.

In the electrocardiogram waveform analysis system described above, the electrocardiogram waveform measured by the Holter electrocardiograph is stored in the management device in association with the identification information of the Holter electrocardiograph. As a result, the management device analyzes the electrocardiogram waveform in association with the identification information of the Holter electrocardiograph. Also, the input unit of the management device acquires the electrocardiogram waveform and the identification information when the main body is connected to the management device by wire or short-range wireless communication. Therefore, the Holter electrocardiograph is transported together with the main body to the place where the management device is installed. That is, the main body of the Holter electrocardiograph will not remain with the medical staff, and the same Holter electrocardiograph will not be reused by the medical staff. On the other hand, the storage medium storing the subject information and the identification information of the subject whose electrocardiogram waveform was measured in association with each other can be separated from the main body and left for the medical staff. For this reason, by transmitting the identification information of the Holter electrocardiograph and the analysis result of the electrocardiogram waveform linked to the identification information to the medical staff, the medical staff can measure the electrocardiogram waveform from the identification information. person can be identified. Therefore, the management device can analyze the electrocardiogram waveform without acquiring personal information (for example, name, etc.) of the subject along with the electrocardiogram waveform. Therefore, it is possible to secure the anonymity of the person to be measured with respect to the analysis company.

Next, the processing of the analysis management server 32 will be described with reference to FIG. The electrocardiogram waveform analysis system 1 of this embodiment is configured so that the Holter electrocardiograph 10 can be recycled and reused. When the electrocardiogram waveform of the subject is measured using the Holter electrocardiograph 10, the Holter electrocardiograph 10 storing the electrocardiogram waveform of the subject is transferred together with the main body 12 to the place where the analysis management server 32 is installed ( for example, to an analysis center). The analysis management server 32 acquires various information from the Holter electrocardiograph 10 transferred to the analysis center, analyzes the electrocardiogram waveform, and determines whether the Holter electrocardiograph 10 is reusable. do.

Before explaining the processing of the analysis management server 32, the procedure for measuring the electrocardiogram waveform of the subject using the Holter electrocardiograph 10 will be explained. When measuring a subject's electrocardiogram waveform using the Holter electrocardiograph 10, first, a medical professional attaches the Holter electrocardiograph 10 to the subject. Specifically, the medical staff fixes the electrodes 14 of the Holter electrocardiograph 10 at appropriate positions near the subject's heart. At this time, the medical staff enters the name of the subject in the name entry column of the recording sheet 20 enclosed with the Holter electrocardiograph 10 . The record sheet 20 is kept by the medical staff. Further, the medical staff inputs information to the user terminal 70 so as to associate the identification information of the Holter electrocardiograph 10 with the subject. For example, the medical staff inputs the identification information of the Holter electrocardiograph 10 used for the subject's electronic medical record.

When the Holter electrocardiograph 10 is attached to the subject, the Holter electrocardiograph 10 measures the subject's electrocardiogram waveform for a predetermined period of time. After a predetermined period of time, the Holter electrocardiograph 10 is removed by the medical staff. The medical staff transports the removed Holter electrocardiograph 10 together with the body 12 to the analysis center by home delivery or the like. After a predetermined period of time has passed, the subject may remove the Holter electrocardiograph 10 by himself/herself and transport the Holter electrocardiograph 10 together with the main body 12 to the analysis center. Hereinafter, the Holter electrocardiograph 10 transferred to the analysis center may be referred to as "the relevant Holter electrocardiograph 10".

When the Holter electrocardiograph 10 arrives at the analysis center, the analysis management server 32 acquires identification information from the Holter electrocardiograph 10, as shown in FIG. 2 (S12). Specifically, the input unit 44 is wired to the output port (not shown) of the main body 12 of the Holter electrocardiograph 10, and the identification information (not shown) stored in the memory 18 of the Holter electrocardiograph 10 from the output port. hereinafter also referred to as the identification information). The input identification information is stored in the electrocardiogram information storage unit 36 .

Next, the analysis management server 32 transmits the identification information obtained in step S12 to the sales management server 50 (S14). Specifically, the transmission/reception unit 46 transmits the identification information stored in the electrocardiogram information storage unit 36 to the sales management server together with information indicating that the Holter electrocardiograph 10 to which the identification information has been attached has arrived at the analysis center. 50 to the transmitting/receiving unit 58 . This notifies the sales management server 50 that the Holter electrocardiograph 10 has arrived at the analysis center (that is, changed from being measured to being analyzed).

Next, the analysis management server 32 acquires an electrocardiogram waveform from the Holter electrocardiograph 10 (S16). Specifically, the input unit 44 inputs the electrocardiogram waveform stored in the memory 18 of the Holter electrocardiograph 10 from the output port of the Holter electrocardiograph 10 . Note that the analysis management server 32 may acquire the electrocardiogram waveform at the same time as the identification information acquired in step S12. The input electrocardiogram waveform is stored in the electrocardiogram information storage unit 36 in association with the identification information acquired in step S12.

Next, the analysis unit 40 analyzes the electrocardiogram waveform acquired in step S16 (S18). Since a known method can be used for analyzing the electrocardiogram waveform, detailed description thereof will be omitted. The analysis result of the electrocardiogram waveform analyzed by the analysis unit 40 is stored in the memory 34 in association with the identification information acquired in step S12.

Next, the analysis management server 32 transmits the analysis result of the electrocardiogram waveform analyzed in step S18 to the storage device 60 together with the identification information (S20). By storing the analysis results in the storage device 60, the user terminal 70 can access the storage device 60 and receive the analysis results. In this embodiment, the medical staff obtains the analysis result from the storage device 60 using the user terminal 70, but the configuration is not limited to this. The analysis results may be printed out on paper and sent to medical personnel.

In this embodiment, the analysis management server 32 acquires the identification information of the Holter electrocardiograph 10 and the electrocardiogram waveform, but does not acquire the subject's personal information. For this reason, the analysis provider associates the analysis result of the electrocardiogram waveform only with the identification information of the Holter electrocardiograph 10, and cannot specify the subject corresponding to the analysis result. On the other hand, since the medical staff manages the identification information of the Holter electrocardiograph 10 and the personal information of the subject in association with each other, the electrocardiogram of the subject is obtained based on the identification information of the Holter electrocardiograph 10. Waveform analysis results can be properly collated. As a result, the anonymity of the subject to the analysis company can be secured.

Next, the analysis management server 32 acquires information on the number of times of use from the Holter electrocardiograph 10 (S22). Specifically, the input unit 44 inputs information about the number of times of use stored in the memory 18 of the Holter electrocardiograph 10 from the output port of the Holter electrocardiograph 10 . The analysis management server 32 may acquire the information on the number of times of use at the same time as the identification information acquired in step S12 and the electrocardiogram waveform acquired in step S16. The input information about the number of times of use is stored in the electrocardiogram information storage unit 36 in association with the identification information acquired in step S12.

Next, the determination unit 42 determines whether or not the number of times of use obtained in step S22 exceeds a predetermined number (S24). In this embodiment, the Holter electrocardiograph 10 can be reused, but repeated reuse will degrade the Holter electrocardiograph 10 . For this reason, the upper limit of the number of times the Holter electrocardiograph 10 is used is set in advance. That is, the predetermined number is the upper limit of the number of times the Holter electrocardiograph 10 is used. If the number of uses of the Holter electrocardiograph 10 exceeds the predetermined number (YES in step S24), it is determined that the Holter electrocardiograph 10 has deteriorated due to use. Therefore, the determination unit 42 decides to discard the Holter electrocardiograph 10 (S34), and the transmission/reception unit 46 transmits the identification information and information indicating that the discard has been decided to the transmission/reception unit 58 of the sales management server 50 (hereinafter referred to as , also called discard decision information) is transmitted (S36).

On the other hand, if the number of uses of the Holter electrocardiograph 10 does not exceed the predetermined number (NO in step S24), it is determined that the Holter electrocardiograph 10 has not deteriorated due to multiple uses. That is, the Holter electrocardiograph 10 is determined to be reusable based on the number of times of use. Next, the analysis management server 32 acquires manufacturing information from the Holter electrocardiograph 10 (S26). Specifically, the input unit 44 inputs the manufacturing information stored in the memory 18 of the Holter electrocardiograph 10 from the output port of the Holter electrocardiograph 10 . The analysis management server 32 may acquire the manufacturing information at the same time as the identification information acquired in step S12, the electrocardiogram waveform acquired in step S16, and the information on the number of times of use acquired in step S22. The input manufacturing information is stored in the electrocardiogram information storage unit 36 in association with the identification information acquired in step S12.

Next, the determination unit 42 determines whether or not a predetermined period has passed since the manufacturing date specified from the manufacturing information acquired in step S26 (S28). Even if the number of times of use of the Holter electrocardiograph 10 is within a predetermined number, there is a possibility that the Holter electrocardiograph 10 will deteriorate over time after a predetermined period of time has passed since the date of manufacture. Therefore, if a predetermined period of time has elapsed since the date of manufacture, the Holter electrocardiograph 10 may have deteriorated even if the number of times of use has not reached the predetermined number, and is not suitable for reuse. be judged. If the predetermined period has passed since the date of manufacture (YES in step S28), the analysis management server 32 decides to discard the Holter electrocardiograph 10 (S34), and the transmission/reception unit 46 transmits/receives the The identification information and the discard decision information are transmitted to the unit 58 (S36).

On the other hand, if the predetermined period has not elapsed since the date of manufacture (NO in step S28), it is determined that the Holter electrocardiograph 10 has not deteriorated over time. In other words, the Holter electrocardiograph 10 is determined to be reusable based on the elapsed time from the date of manufacture. Next, the analysis management server 32 acquires information on the number of writing errors from the Holter electrocardiograph 10 (S30). Specifically, the input unit 44 inputs information about the number of write errors stored in the memory 18 of the Holter electrocardiograph 10 from the output port of the Holter electrocardiograph 10 . It should be noted that the analysis management server 32, at the same time as the identification information obtained in step S12, the electrocardiogram waveform obtained in step S16, the information about the number of times of use obtained in step S22, and the manufacturing information obtained in step S26, obtains information regarding the number of writing errors. may be obtained. The input information about the number of write errors is stored in the electrocardiogram information storage unit 36 in association with the identification information acquired in step S12.

Next, the determination unit 42 determines whether or not the number of write errors acquired in step S30 exceeds a predetermined number (S32). The memory 34 of the Holter electrocardiograph 10 may deteriorate even if the number of times of use is within a predetermined number and a predetermined period of time has not elapsed since the date of manufacture. Degradation of the memory 34 can be, for example, an increase in the number of unusable cells among the plurality of cells included in the memory 34 . Since a write error occurs when writing to an unusable cell, deterioration of the memory 34 can be predicted from the number of write errors. For this reason, the upper limit of the number of occurrences of write errors during measurement is set in advance. If the number of write errors is equal to or greater than the predetermined number (YES in step S32), it is determined that the memory 34 of the Holter electrocardiograph 10 is likely degraded. Therefore, the analysis management server 32 decides to discard the Holter electrocardiograph 10 (S34), and the transmission/reception unit 46 transmits the identification information and the discard decision information to the transmission/reception unit 58 of the sales management server 50 (S34). S36).

On the other hand, if the number of write errors is less than the predetermined number (NO in step S32), it is determined that the memory 34 of the Holter electrocardiograph 10 has not deteriorated to the point where it cannot be reused. That is, the Holter electrocardiograph 10 is determined to be reusable based on the number of write errors. Therefore, the Holter electrocardiograph 10 is determined to be reusable based on any of the number of times of use, the elapsed time from the date of manufacture, and the number of writing errors. Therefore, the determining unit 42 decides to recycle the Holter electrocardiograph 10 (S38), and the transmitting/receiving unit 46 sends the transmitting/receiving unit 58 of the sales management server 50 the identification information and the information indicating that the recycling has been decided. (hereinafter also referred to as recycle determination information) is transmitted (S40).

In this embodiment, the determination unit 42 determines whether or not the used Holter electrocardiograph 10 is reusable based on information such as the number of times of use, manufacturing information, and the number of write errors. That is, the determination unit 42 determines whether or not the Holter electrocardiograph 10 is likely to fail. As a result, the reuse of the Holter electrocardiograph 10 can be stopped before the Holter electrocardiograph 10 actually breaks down, and the safety of the Holter electrocardiograph 10 to be reused can be ensured.

When the processing of the analysis management server 32 is completed, the Holter electrocardiograph 10 is transported to a facility such as a recycling center, for example, and processed for recycling. The processing for recycling includes, for example, cleaning processing for infection prevention, replacement processing of the electrodes 14, replacement processing of the battery (not shown) mounted on the main body 12 of the Holter electrocardiograph 10, Holter electrocardiograph 10 can be reused, packaging of the Holter electrocardiograph 10 and a new recording sheet 20, and the like. The Holter electrocardiograph 10 that has undergone the recycling process can be provided to the medical staff again, and is kept in stock in the warehouse of the sales manager until it is provided to the medical staff. When the recycling process is completed, a terminal (not shown) installed at a facility such as a recycling center or a facility for inventory management sends information indicating that the Holter electrocardiograph 10 is in stock to the sales management server 50. Send.

In this embodiment, the information on the number of times the Holter electrocardiograph 10 has been used and the manufacturing information are stored in the memory 18 of the Holter electrocardiograph 10, but the configuration is not limited to this. Information about the number of times the Holter electrocardiograph 10 has been used and manufacturing information may be linked to the identification information of the Holter electrocardiograph 10 and input to the analysis management server 32 . For example, information about the number of times the Holter electrocardiograph 10 has been used and manufacturing information may be stored in the management information storage unit 54 of the sales management server 50 . The analysis management server 32 may acquire information about the number of times the Holter electrocardiograph 10 has been used and manufacturing information from the sales management server 50 based on the identification information input from the Holter electrocardiograph 10 .

Next, processing of the sales management server 50 will be described. First, the process of updating the management information by the sales management server 50 based on the information received from the analysis management server 32 will be described. The sales management server 50 is communicably connected to other devices such as the analysis management server 32, and can identify the Holter electrocardiograph 10 from other devices when the state of the Holter electrocardiograph 10 is changed. Receive information and information about the changed state of the Holter monitor 10 . The sales management server 50 updates the management information corresponding to the received identification information to information indicating the received state of the Holter electrocardiograph 10 .

For example, in the process of step S14 in FIG. 2, the transmitting/receiving unit 46 of the analysis management server 32 sends the transmitting/receiving unit 58 identification information of the Holter electrocardiograph 10 arriving at the analysis center and Send information that you have arrived at In this case, the sales management server 50 updates the management information corresponding to the received identification information among the management information stored in the management information storage unit 54 to information indicating the state of analysis processing. Also, in the processing of step S36 in FIG. In this case, the sales management server 50 updates the management information corresponding to the received identification information among the management information stored in the management information storage unit 54 to information indicating the discarded state. Also, in the processing of step S40 in FIG. In this case, the sales management server 50 updates the management information corresponding to the received identification information among the management information stored in the management information storage unit 54 to information indicating the state of recycling processing.

The sales management server 50 also receives information about the state of the Holter electrocardiograph 10 from a terminal (not shown) installed at a facility such as a recycling center or a facility for managing inventory. When the Holter electrocardiograph 10 is determined to be recycled in the process of step S38 in FIG. 2, the Holter electrocardiograph 10 is recycled at a facility such as a recycling center, and becomes reusable. Then, a terminal installed in a facility such as a recycling center or a facility for managing inventory transmits identification information and information indicating the inventory status to the transmitting/receiving unit 58 . In this case, the sales management server 50 updates the management information corresponding to the received identification information among the management information stored in the management information storage unit 54 to information indicating the inventory status.

Next, processing for updating management information and user information by the sales management server 50 based on information received from the user terminal 70 will be described. First, the processing of the sales management server 50 when a medical worker orders the Holter electrocardiograph 10 from the user terminal 70 will be described. When the medical staff operates the user terminal 70 to place an order for the Holter electrocardiograph 10 , the transmitting/receiving unit 58 receives the order number information for the Holter electrocardiograph 10 input from the input unit 74 of the user terminal 70 . . Then, the sales management server 50 selects, from the management information stored in the management information storage unit 54, the identification information of the Holter electrocardiographs 10 having the information indicating the status of being in stock for the number of orders. The sales management server 50 then transmits an instruction to the terminal (not shown) of the facility that manages the inventory to send the Holter electrocardiograph 10 corresponding to the selected identification information to the medical worker who ordered it. Furthermore, the sales management server 50 updates the management information corresponding to the identification information of the selected Holter electrocardiograph 10 among the management information stored in the management information storage unit 54 to the information indicating the possession state. The sales management server 50 also causes the user information storage unit 56 to store the input number of orders and the identification information of the selected Holter electrocardiograph 10 . Note that the processing of the sales management server 50 is not limited to the configuration described above. For example, the sales management server 50 may output only order information regarding the number of orders and the orderer (medical worker who placed the order) to the terminal of the inventory management facility. Based on the order information, the inventory management facility ships the ordered number of Holter electrocardiographs 10 to the orderer. At that time, the identification information of the shipped Holter electrocardiograph is input to the terminal of the inventory management facility. The input identification information is transmitted to the sales management server 50 together with information specifying the orderer who has shipped. The sales management server 50 may update the management information stored in the management information storage unit 54 based on the information transmitted from the terminal of the inventory management facility.

Next, processing of the sales management server 50 when a medical worker uses the Holter electrocardiograph 10 will be described. When using the Holter electrocardiograph 10, the medical staff inputs the identification information of the Holter electrocardiograph 10 to be used to the user terminal 70, and the input identification information is used for the Holter electrocardiograph 10. is transmitted to the sales management server 50 together with information indicating that the When the identification information is received from the user terminal 70, the sales management server 50 converts the management information corresponding to the received identification information among the management information stored in the management information storage unit 54 into information indicating the state of measurement. Update. Also, the sales management server 50 erases the received identification information from the user information stored in the user information storage unit 56 . As a result, in the user information, the identification information of the Holter electrocardiograph 10 being measured is deleted from the identification information of the Holter electrocardiograph 10 held by the relevant medical staff. That is, at approximately the same timing as when the medical staff lent the Holter electrocardiograph 10 to the subject, the user information indicates that the number of Holter electrocardiographs 10 possessed by the medical staff decreases. Updated.

After that, the sales management server 50 compares the order number information and the holding information of the medical staff in the user information. If the number specified by the holding information is smaller than the number specified by the order quantity information, the sales management server 50 generates the same number of Holter electrocardiograms as the difference between the number specified by the holding information and the number specified by the order quantity information. Send instructions to ship a total of 10 to the appropriate HCP. Specifically, the sales management server 50 selects, from the management information stored in the management information storage unit 54, the identification information of the Holter electrocardiographs 10 having the information indicating the state of being in stock in the same number as the difference. do. The sales management server 50 then transmits an instruction to the terminal (not shown) of the facility that manages the inventory to send the Holter electrocardiograph 10 corresponding to the selected identification information to the medical worker who ordered it. In addition, the sales management server 50 updates the corresponding management information and user information for the shipped Holter electrocardiograph 10 . As a result, when the number of Holter electrocardiographs 10 owned by a medical worker is less than the number of orders, a supplemental Holter electrocardiograph 10 is automatically shipped. )can do. As already explained, the processing of the sales management server 50 is not limited to the configuration described above, and other configurations may be adopted.

The order quantity information may include information on the maximum number and the minimum number of Holter electrocardiographs 10 desired by the medical staff. In this case, the sales management server 50 transmits an instruction to ship the Holter electrocardiographs 10 when the number specified by the holding information becomes less than the minimum number specified by the order number information. At this time, the number of Holter electrocardiographs 10 to be shipped is the difference between the maximum number specified by the order quantity information and the number specified by the possession information. Also, the sales management server 50 may acquire the order quantity information not from the user terminal 70 but from another terminal (for example, a terminal owned by a distributor of the Holter electrocardiograph 10).

Also, in the user information, the timing at which the identification information included in the information held by each medical worker is deleted (that is, the number of Holter electrocardiographs 10 held by each medical worker is decreased in the user information) is It may be the timing at which the sales management server 50 acquires the identification information from the analysis management server 32 in step S14 of FIG. 2 (the timing at which the arrival of the Holter electrocardiograph 10 at the analysis center is communicated). If the medical staff does not input the identification information of the Holter electrocardiograph 10 to be used to the user terminal 70, the management information is not updated from the possessed state to the measuring state. For this reason, after the Holter electrocardiograph 10 arrives at the analysis center, the sales management server 50 updates the management information of the Holter electrocardiograph 10 from the possession state to the analysis state, and also changes the user information to the current state. The identification information of the Holter electrocardiograph 10 may be erased. Even in such a case, if the number of Holter electrocardiographs 10 owned is less than the number of orders, the supplemental Holter electrocardiographs 10 are automatically shipped. stock).

(Example 2)
In Example 1 above, the Holter electrocardiograph 10 was recycled and reused, but the configuration is not limited to this. The Holter monitor 10 may be non-reusable and usable only once. In this embodiment, the configuration used for reusing the Holter electrocardiograph 10 is different from the electrocardiogram waveform analysis system 1 of the first embodiment, and other configurations are substantially the same. Therefore, the description of the same configuration as that of the electrocardiogram waveform analysis system 1 of the first embodiment will be omitted.

As shown in FIG. 3 , the electrocardiogram waveform analysis system 2 of this embodiment includes a Holter electrocardiograph 10 , a management device 130 , a storage device 60 and a user terminal 70 . The Holter electrocardiograph 10, the storage device 60, and the user terminal 70 have substantially the same configurations as those of the Holter electrocardiograph 10, the storage device 60, and the user terminal 70 of the first embodiment. omitted.

The management device 130 has an analysis management server 132 and a sales management server 150 . Analysis management server 132 is configured using a computer including memory 34 and CPU 138 . A calculation program is stored in the memory 34, and when the CPU 138 executes the program, the CPU 138 functions as the analysis unit 40 shown in FIG. That is, unlike the CPU 38 of the first embodiment, the CPU 138 does not function as a determination unit. As described above, in this embodiment, the Holter electrocardiograph 10 is not reused. Therefore, there is no need to determine the state of the Holter electrocardiograph 10 (for example, whether it is usable, whether it is being recycled, whether it has been discarded, etc.), and the determining unit is not required. Since there is no need to determine the state of the holder electrocardiograph 10 , there is no need to store the number of uses of the holder electrocardiograph 10 in the memory 12 , nor is it necessary to store the number of write errors in the memory 12 . For this reason, the configuration may be such that these pieces of information are not stored in the memory 12 . Note that the memory 34 has substantially the same configuration as the memory 34 of the first embodiment, so detailed description thereof will be omitted. In addition, the analysis management server 132 includes an input unit 44 and a transmission/reception unit 46. The input unit 44 and the transmission/reception unit 46 have substantially the same configuration as the input unit 44 and the transmission/reception unit 46 of the first embodiment. , detailed description is omitted.

The sales management server 150 is configured using a computer including a memory 152 and a CPU (not shown). The memory 152 has an inventory information storage section 154 and a user information storage section 56 . The inventory information storage unit 154 stores identification information of Holter electrocardiographs 10 that can be provided to medical personnel (that is, Holter electrocardiographs 10 in stock). Note that the user information storage unit 56 has substantially the same configuration as the user information storage unit 56 of the first embodiment, so detailed description thereof will be omitted. Further, the sales management server 150 includes a transmission/reception unit 58. The transmission/reception unit 58 has substantially the same configuration as that of the transmission/reception unit 58 of the first embodiment, so detailed description thereof will be omitted. As described above, in this embodiment, the Holter electrocardiograph 10 is not reused. For this reason, the sales management server 150 manages only whether the Holter electrocardiograph 10 is owned by a medical worker or in an inventory state, and determines to which medical worker the Holter electrocardiograph 10 has been provided. You just need to manage whether

Processing of the analysis management server 132 will be described. The analysis management server 132 acquires various kinds of information from the Holter electrocardiograph 10 transferred to the analysis center and analyzes the electrocardiogram waveform. Therefore, also in this embodiment, the processing of steps S12 to S20 in FIG. 2 is executed. On the other hand, when the measured electrocardiogram waveform is read out to the analysis management server 132, the used Holter electrocardiograph 10 is discarded. Therefore, in this embodiment, the processes of steps S22 to S40 in FIG. 2 are not executed, and the analysis management server 132 terminates the process after the process of step S20.

Processing of the sales management server 150 will be described. When the transmission/reception unit 58 receives the order number information of the Holter electrocardiograph 10 input from the input unit 74 of the user terminal 70 , the sales management server 150 orders the identification information from the information stored in the inventory information storage unit 154 . Select only a number. The sales management server 150 then transmits an instruction to ship the Holter electrocardiograph 10 corresponding to the selected identification information to the medical staff who ordered it, to the terminal (not shown) of the facility that manages the inventory. Furthermore, the sales management server 150 deletes the selected identification information from the inventory information storage unit 154 and stores it in the user information storage unit 56 . Also, the sales management server 50 stores the input order quantity in the user information storage unit 56 .

Also, when a medical worker uses the Holter electrocardiograph 10 , the sales management server 150 receives the identification information of the used Holter electrocardiograph 10 from the user terminal 70 . Next, the sales management server 50 erases the received identification information from the user information stored in the user information storage unit 56. FIG. As a result, in the user information, the identification information of the Holter electrocardiograph 10 being measured is deleted from the identification information of the Holter electrocardiograph 10 held by the relevant medical staff. Also in this embodiment, if the medical staff does not input the identification information of the Holter electrocardiograph 10 to be used to the user terminal 70, the Holter electrocardiograph 10 will be sold after it arrives at the analysis center. The management server 150 may erase the identification information of the Holter electrocardiograph 10 from the user information. After that, the sales management server 150 automatically ships the missing Holter electrocardiograph 10 to the medical staff. In addition, since the configuration of the automatic shipping process is substantially the same as that of the first embodiment, detailed description thereof will be omitted.

In the present embodiment as well, a new Holter electrocardiograph 10 is shipped to the medical staff, and the Holter electrocardiograph 10 is transported to the analysis operator together with the main unit 12. There is no need for maintenance or work such as obtaining measurement data from the Holter electrocardiograph 10 . Therefore, the burden on medical staff can be reduced. In addition, when the number of Holter electrocardiographs 10 held is less than the number of orders, the number of Holter electrocardiographs 10 to be replenished is automatically shipped. .

In Embodiments 1 and 2 above, the sales management servers 50 and 150 manage the number of Holter electrocardiographs 10 owned and ordered by each medical worker, and automatically Although the supplementary Holter electrocardiograph 10 was automatically shipped to the medical staff, the configuration is not limited to this. The sales management server does not have to manage the number of Holter electrocardiographs 10 owned by each medical worker and the number of orders. In other words, medical personnel may replenish the required number of Holter electrocardiographs 10 by ordering Holter electrocardiographs 10 as needed.
