Description

  The present invention relates to a medical information processing system and program for transmitting medical information data to a remote place.

  In recent years, a telemedicine support system has been proposed in order to obtain support from a remote place of an experienced doctor in medical practice such as examination and treatment of various lesions.

  This telemedicine support system is a medical information data in which, for example, an image signal obtained by photographing a lesioned part and a treatment tool for treating the lesioned part in an operating room, driving conditions of the treatment tool, patient information, and the like are converted into data. Is generated and transmitted in real time to a remote doctor via a public line or a dedicated line. The doctor at the remote site creates and transmits the advice instruction information for the treatment action from the lesion image reproduced, based on the medical information data transmitted in real time, the driving condition of the treatment tool, the patient information, etc. The reply is superimposed on the medical information data. The medical information data on which the advice instruction returned from the doctor at the remote place is superimposed is reproduced and displayed in the operating room, and the treatment action is performed in accordance with the advice instruction.

  As described above, it is important to ensure the security of data transmission in order to prevent leakage of medical information data to a third party when various types of medical information data are transmitted and received between remote locations in order to seek medical advice. It becomes. In order to ensure the security of this data transmission, data to be transmitted is generally encrypted.

  As described above, this medical information data includes a lot of data such as image data of a lesioned part, type of treatment tool and driving condition data, patient information data, and the like, in order to encrypt these data. It takes a lot of time. In addition, it takes a lot of time to decrypt the encrypted and transmitted medical information data. If a long time is required for encryption and decryption in this way, real-time advice and instructions during treatment cannot be performed, and the treatment may be hindered.

Therefore, among the medical information data, information related to personal privacy such as name, date of birth, medical history, etc., which is personal information of the patient being treated, images of the affected area, driving conditions of the treatment instrument, etc. Ensuring patient information security by encrypting and transmitting only patient information related to the patient's privacy by dividing it into information that is difficult to identify individual patients. A telemedicine support system has also been proposed in which the video information data of the treatment affected area, the type of the treatment treatment tool, and the driving condition data are transmitted without being encrypted, and the medical information is transmitted in real time (for example, patent document) 1).
Japanese Patent Application Laid-Open No. 2003-70804.

  Conventionally, in telemedicine support systems, medical information data is encrypted to ensure the security of transmitted medical information data. In order to secure the real-time system of the medical information data from the time required for the encryption of the medical information data and the decryption of the received code, a method of encrypting and transmitting only the patient personal information data is also proposed in Patent Document 1. Yes.

  On the other hand, the required security level differs depending on the destination of medical information data. For example, the level of security differs between the transmission of medical information data using a dedicated line inside a hospital and the transmission of medical information data using a public line outside the hospital, and the encryption format depends on the security level. It is desirable to be able to change this.

  It is desirable to provide a security level according to the destination, and to select and set the range of data to be encrypted and the encryption type. However, the complexity of the selection setting and the data leakage when the selection setting is forgotten. For the fear, the same data range and encryption form are generally used without distinguishing the transmission destination.

  For this reason, since the security strength is higher than necessary and much time is required for encryption and decryption processing, there is a possibility that a problem may occur in the real-time property of medical practice.

  Therefore, there is a demand for a medical information processing system that can select an encryption form according to a destination of medical information data and automatically ensure a necessary security level.

A transmission destination instruction means for requesting encryption setting information in an encryption form possessed by the transmission destination, encryption setting information from the transmission destination instructed by the transmission destination instruction means, and a basis of the read encryption setting information. The communication means for converting the medical information data generated by the medical information data generation means into a cipher of a predetermined encryption form, and the communication for transmitting the medical information data encrypted by the encryption means to the transmission destination And means.

  The transmission destination instructing means of the medical information processing system of the present invention has an identification code for identifying a plurality of transmission destinations, and indicates the transmission destination of medical information data by the identification code.

  The program of the present invention is a program executed by a predetermined computer, medical information data processing for generating medical information data, and transmission destination instruction processing for instructing a transmission destination of medical information data generated by the medical information data processing, The encryption setting information corresponding to the transmission destination instructed in the transmission destination instruction processing is read, and the medical information data generated by the medical information data processing based on the encryption setting information is encrypted in a predetermined encryption form. And an encryption process for conversion, and a communication process for transmitting the medical information data encrypted by the encryption process to the transmission destination.

  The medical information processing system and program of the present invention can ensure the security of medical information data according to the destination of the medical information data, and can eliminate the complexity of security setting input by the medical staff.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. A first embodiment of a medical information processing system according to the present invention will be described with reference to FIGS. 1, 2, 4, and 5. FIG. 1 is a block diagram showing the overall configuration of a medical information processing system according to the present invention.

It is a flowchart explaining the reading processing operation | movement of the encryption setting information of a form.

  As shown in FIG. 1, the medical information processing system of the present invention includes in-hospital signal processing devices 11a, 11b, and 11c installed in predetermined operating rooms, endoscope treatment rooms, examination rooms, etc. Connected to the network 12. This in-hospital network 12 is connected to an external network 14 via a gateway server 13. This external network 14 is connected to other hospitals outside the hospital 10 or out-of-hospital signal processing devices 15a, 15b provided in an ambulance or the like.

  As shown in FIG. 2, the internal configuration of the in-hospital signal processing devices 11a to 11c of the hospital 10 includes a CPU 20, a memory 21, an HDD 22, an input I / F 23, a graphic controller 24, and a communication I / F 25.

  The CPU 20 drives and controls the memory 21, HDD 22, input I / F 23, graphic controller 24, and communication I / F 25 via a bus. The CPU 20 is a microprocessor that incorporates a program for processing various types of information and uses the program to control the drive of the memory 21, HDD 22, input I / F 23, graphic controller 24, and communication I / F 25 and perform various types of information processing. is there.

  The memory 21 and the HDD 22 write and store data generated by information processing in the CPU 20, the memory 21 is a semiconductor storage element, and the HDD 22 is a hard magnetic storage medium.

  The input I / F 23 is an interface between the CPU 20 and an input unit (not shown) such as a keyboard, mouse, doctor remote controller, or release switch for inputting various information or processing instructions.

  The graphic controller 24 is driven and controlled by the CPU 20 to generate an image signal of a graphic image for displaying processed information on a display (not shown).

  The communication I / F 25 is an interface that transmits and receives various kinds of information to and from the in-hospital signal processing apparatus 11 through the in-hospital network 12 or between the in-hospital network 12 and the external network 14 through the gateway server 13.

  The out-of-hospital signal processing devices 15a and 15b have the same basic configuration as the in-hospital signal processing devices 11a to 11c. The in-hospital signal processing devices 11a to 11b are referred to as the in-hospital signal processing device 11 unless otherwise distinguished, and the out-of-hospital signal processing devices 15a and 15b are also referred to as in-hospital signal processing unless otherwise distinguished. This will be referred to as device 15.

  The processing operation of the in-hospital signal processing apparatus 11 of the hospital 10 will be described with reference to FIG. This processing operation is performed in the in-hospital signal processing device 11a installed in the operating room of the hospital 10, for example, to other in-hospital signal processing devices 11b and 11c in the hospital 10 or out-of-hospital signal processing devices 15a and 15b. This is information data transmission processing.

  The surgeon uses the keyboard, mouse, doctor remote control, or release switch to instruct the CPU 20 to start a medical information data transmission processing mode via the input I / F 23, and the CPU 20 performs medical information data transmission processing. The mode is started (step S1).

  Next, in step S2, the CPU 20 obtains transmission destination instruction information of medical information input by the operator using the keyboard, mouse, doctor remote controller, or release switch. For this transmission destination instruction input, for example, a plurality of buttons that can be assigned to the doctor remote controller are prepared, a transmission destination is assigned to these buttons, and a destination instruction is input by operating the assigned key.

  In addition to the key assignment of the doctor remote controller, this destination designation input is performed by inputting the destination information directly from the keyboard, or by using the cursor to select a desired destination from a plurality of destinations displayed on the display with a mouse. There are methods such as selective input. That is, the transmission destination input with the doctor remote controller, the keyboard, the mouse, or the like is converted into an identification code, and the transmission destination is designated to the CPU 20 by the identification code.

  When the transmission destination instruction is input in step S2, the CPU 20 reads the encryption setting information corresponding to the transmission destination instructed in step S2 from the memory 21 in step S3.

  On the other hand, when the medical information data transmission processing mode in step S1 starts, the CPU 20 performs medical information data generation processing in step S4 in parallel with the processing in steps S2 and S3. This medical information data includes patient information data such as sex, age, name, etc. for identifying a patient, diseased part image information generated by an endoscope apparatus or ultrasonic diagnostic apparatus, and treatment part information data of treatment tool drive information, etc. It is.

  The medical information data including the patient information data and the treatment affected part information data is taken into the in-hospital signal processing apparatus 11 from the endoscope apparatus or the ultrasonic diagnostic apparatus and is temporarily stored. Alternatively, an affected part image generated by an endoscope or an ultrasonic diagnostic device is taken into the in-hospital signal processing apparatus 11 and patient information and treatment tool drive information are input from a keyboard connected to the in-hospital signal processing apparatus 11 Then, the medical information data is generated in the in-hospital signal processing apparatus 11. That is, any one of generation methods of the external generation generated in the endoscope apparatus and the ultrasonic diagnostic apparatus connected to the in-hospital signal processing apparatus 11 and the internal generation generated in the in-hospital signal processing apparatus 11 is used. It is done.

  Next, in step S5, the CPU 20 performs an encryption process on the medical information data generated in step S4 using the encryption setting information read in step S3. Next, in step S6, the CPU 20 transmits the medical information data encrypted in step S5 from the communication I / F 25 to the destination instructed for input in step S2, and performs this medical information data transmission processing. The mode is terminated (step S7).

  Next, the encryption setting information reading process in step S3 will be described with reference to FIG. When the process proceeds to reading of the encryption setting information in step S3, the CPU 20 acquires the destination information instructed to be input in step S2 in step S11. Next, in step S12, the CPU 20 selectively reads out the encryption setting information corresponding to the transmission destination acquired in step S11 from the memory 21. When the encryption setting information in step S12 is read, the encryption setting information reading process in step S3 ends (step S13).

  For example, if the transmission destination instruction in step S2 is directed to the in-hospital signal processing device 11c of the hospital 10 in FIG. 1, the processing in step S12 is performed in the in-hospital signal processing device 11c in step S12. Corresponding encryption setting information is selectively read out. If the transmission destination instruction in step S2 is directed to the out-of-hospital signal processing device 15a connected to the external network 14 in FIG. 1, the encryption setting corresponding to the out-of-hospital signal processing device 15a in step S12. Information is read.

  That is, in the case of the in-hospital signal processing devices 11b and 11c in the hospital 10 connected to the in-hospital network 12 where the security information data from the in-hospital signal processing device 11a of the hospital 10 is sufficiently secured, Sending information without encryption with emphasis on real-time information, or minimizing information items to be encrypted, such as only the name of patient information in the medical information data to be encrypted. An encryption method with a relatively low encryption rate and a short length is used. In addition, when the out-of-hospital signal processing devices 15a and 15b are transmission destinations, in order to increase the security of medical information leakage, the number of information items of medical information data to be encrypted is increased, and at least patient information is completely encrypted and encrypted. An encryption method with a high encryption rate such as a relatively long key or a combination of a plurality of encryption methods is used.

  As described above, the medical information system according to the first embodiment of the present invention presets the encryption method according to the transmission destination of the medical information data and the encryption setting information having the encryption program, By creating and storing destination data by associating the preset encryption setting information with the destination, and selecting the destination from the destination data, the encryption process according to the security level of the destination can be performed. It is performed and medical information data is transmitted.

  Although the transmission destination and the encryption setting information are described above as being stored in the memory 21, they may be stored in the HDD 22. Further, when medical information data is transmitted to a destination not stored in the memory 21 or the HDD 22, the destination and the encryption of the destination are transmitted via the input I / F 23 from a keyboard, a doctor remote controller or the like. Setting information may be input directly.

  Moreover, although it demonstrated that the production | generation process of the medical information data of step S4 was performed in parallel with the process of the said step S2 and S3, it is not necessarily required to perform a parallel process, The medical information data generation process of step S4 is, for example, The medical information data generation process in step S4 may be performed after the start of the medical information data transmission process mode in step S1, and then the transmission destination instruction process in step S2 may be performed. After the transmission destination instruction process in step S2, The medical information data generation process in step S4 may be performed, and thereafter the encryption setting information reading process in step S3 may be performed. Further, after the encryption setting information reading process in step S3, the medical information in step S4 may be performed. Information data generation processing may be performed, and then the encryption processing in step S5 may be performed.

  Further, the medical information data in step S4 is externally generated medical information data by an endoscope apparatus, an ultrasonic diagnostic apparatus, or the like connected to the in-hospital signal processing apparatus 11, or internally generated medical data generated in the in-hospital signal processing apparatus 11. The information data may be temporarily stored in the memory 21 or the HDD 22 until it is encrypted and transmitted, and may be deleted after the transmission is completed, or may be continuously stored after the transmission is completed.

  Next, a second embodiment of the medical information system according to the present invention will be described with reference to FIG. FIG. 3 is a block diagram showing the configuration of the in-hospital signal processing apparatus used in the second embodiment of the medical information system according to the present invention.

  The overall configuration of the medical information system according to the second embodiment of the present invention is the same as that of the first embodiment described with reference to FIG. The configuration of the in-hospital signal processing device 11 ′ used in the medical information system according to the second embodiment is shown in FIG. 3, but this in-hospital signal processing device 11 ′ basically includes the in-hospital signal processing device 10 ( The difference is that the cryptographic processing unit 30 is provided, as in FIG.

  This cryptographic processing unit 30 is dedicated to performing only the encryption processing of the medical information data based on drive control from the CPU 20.

  The processing operation of the in-hospital signal processing apparatus 11 ′ of the second embodiment is the same as the basic processing operation of the in-hospital signal processing apparatus 11 of the first embodiment described above with reference to FIGS. 4 and 5. The difference is that the encryption processing unit 30 performs the encryption processing in step S5 by the drive control of the CPU 20.

  That is, in step S5, the CPU 20 drives and controls the encryption processing unit 30, and encryption setting information corresponding to the transmission destination read from the memory 21 or the HDD 22 in step S3 and the medical data generated in step S4. Using the information data, the medical information data is encrypted according to the transmission destination. The medical information data encrypted by the cryptographic processing unit 30 is transmitted from the communication I / F to the transmission destination instructed to input.

  With the medical information system according to the second embodiment, the encryption processing function of the control processing program provided in the CPU 20 of the in-hospital signal processing apparatus 11 ′ can be reduced. Further, by providing the cryptographic processing unit 30, it is possible to perform cryptographic processing without impairing the real-time property of medical information data.

  Next, a third embodiment of the medical information system according to the present invention will be described. The in-hospital signal processing apparatus 11 used in the medical information system according to the third embodiment is the same as the first embodiment described with reference to FIGS. 1 and 2. The memory 21 or the HDD 22 of the in-hospital signal processing apparatus 11 according to the third embodiment does not store the encryption setting information corresponding to the transmission destination, and reads and transmits the encryption setting information provided in the transmission destination. The medical information data is encrypted and transmitted by the encryption setting information transmitted from the transmission destination. The encryption setting information reading process of the third embodiment will be described with reference to FIG.

  When the process proceeds to reading of the encryption setting information in step S3, the CPU 20 acquires the transmission destination instruction information input in step S2 in step S21. Next, in step S22, the CPU 20 makes a transmission request for the encryption setting information set as the transmission destination to the transmission destination acquired in step S21. For example, when the medical information data is transmitted from the in-hospital signal processing device 11a of the hospital 10 to the out-of-hospital signal processing device 15a, the CPU 20 of the in-hospital signal processing device 11a receives a transmission destination instruction that is input via the input I / F 23. From the information, the transmission request for the encryption setting information is made to the out-of-hospital signal processing device 15a via the communication I / F 25, the gateway server 13, and the external network 14.

  Next, in step S23, the CPU 20 reads the encryption setting information transmitted from the transmission destination in response to the transmission request for the encryption setting information in step S22, and stores the encrypted setting information in the memory 21 or the HDD 22 for the first time. The setting information reading process is terminated (step S24).

  That is, even if the encryption setting information set in the out-of-hospital signal processing devices 15a and 15b is unknown, the encryption setting information set in the transmission destination is obtained, and based on the obtained encryption information Perform encryption processing. As a result, encryption suitable for the transmission destination is performed, and medical information data can be transmitted. In addition, when changing the encryption form at the transmission destination, it becomes possible to change the encryption setting information only on the transmission destination side, and the transmission source also obtains and stores the encryption setting information changed in advance from the transmission destination. There is no need to keep it. Further, it is possible to prevent an input error in the encryption information setting of the transmission destination at the transmission source.

  Next, a fourth embodiment of the medical information system according to the present invention will be described. The medical information system according to the fourth embodiment uses the same in-hospital signal processing apparatus 11 ′ as that of the second embodiment described above with reference to FIGS. 1 and 3. The reception and reading process of the encryption setting information of the in-hospital signal processing apparatus 11 ′ of the fourth embodiment is the same as the reception and reading process of the encryption setting information in step S23 described with reference to FIG. Different.

  That is, the in-hospital signal processing device 11 ′ stores the destination encryption setting information transmitted from the out-of-hospital signal processing devices 15a and 15b in the encryption processing unit 30, and encrypts the medical information data by the destination encryption setting information. The unit 30 is driven and controlled to transmit the encryption process. Thereby, the same effect as that of the third embodiment described above can be obtained.

  Next, a fifth embodiment of the medical information system according to the present invention will be described. The medical information system according to the fifth embodiment uses the in-hospital signal processing apparatus 11 described above with reference to FIGS. 1 and 2. The processing operation of the in-hospital signal processing apparatus 11 is similar to that of the third embodiment, but the fifth embodiment not only reads the encryption setting information from the transmission destination but also downloads the encryption program. Can be selected. The encryption setting information reading process according to the fifth embodiment will be described with reference to FIG.

  When the process proceeds to reading of the encryption setting information in step S3, the CPU 20 acquires the destination information instructed to be input in step S2 in step S31. Next, in step S32, the CPU 20 makes a transmission request for the encryption setting information set as the transmission destination to the transmission destination acquired in step S31. For example, when the medical information data is transmitted from the in-hospital signal processing device 11a of the hospital 10 to the out-of-hospital signal processing device 15a, the CPU 20 of the in-hospital signal processing device 11a receives the destination information input via the input I / F 23. To the out-of-hospital signal processing device 15a via the communication I / F 25, the gateway server 13, and the external network 14.

  On the other hand, the transmission destination holds the encryption setting information set for itself and the encryption program. When the encryption program based on the encryption setting information set in the transmission destination is not set in the transmission source, it is necessary to download the encryption program.

  Therefore, the transmission destination makes a selection request as to whether or not it is necessary to download the encryption program based on the encryption setting information in response to the encryption setting information request from the transmission source. In response to the selection request for downloading the encrypted program from the transmission destination, in step S33, the CPU 20 determines whether or not it is necessary to download the encrypted program.

  In this step S33, if it is determined that downloading of the encryption program is unnecessary, that is, the encryption program is stored in the hospital signal processing apparatus 11 from the encryption setting information, and the encryption program from the transmission destination is stored. If it is determined that the download is unnecessary, in step S34, the CPU 20 receives and reads only the encryption setting information transmitted from the transmission destination, and temporarily stores it in the memory 21 or HDD 22, and stores the encryption setting information. The reading process is terminated (step S35).

  If it is determined in step S33 that it is necessary to download the encryption program from the transmission destination, in step S36, the CPU 20 receives and reads the encryption setting information transmitted from the transmission destination, and in parallel with this step S36. In step S37, the encryption program transmitted from the transmission destination is received. In step S38, the encryption program received in step S37 performs program installation processing for writing and storing the encryption program in the memory 21 or the HDD 22. Note that after receiving and reading the encryption setting information in step 36, the encryption program reception and program installation in steps S37 and S38 may be performed.

  When the reception and reading of the encryption setting information in step S36 and the program installation in step S38 are completed, the encryption setting information reading process is ended (step S39).

  That is, even if the encryption setting information set in the out-of-hospital signal processing devices 15a and 15b is unknown and the transmission source does not have the encryption program, the encryption setting information set in the transmission destination Since the encryption program is obtained and the encrypted information is transmitted based on the obtained encrypted information and the encrypted program, it is possible to transmit the encrypted medical information data suitable for the transmission destination. In addition, when changing the encryption form at the transmission destination, it becomes possible to change the encryption setting information only on the transmission destination side, and the transmission source also obtains and stores the encryption setting information changed in advance from the transmission destination. There is no need to keep it. Further, it is possible to prevent an input setting error in the transmission destination encryption information setting at the transmission source.

  Next, a sixth embodiment of the medical information system according to the present invention will be described. In the sixth embodiment, the in-hospital signal processing apparatus 11 ′ described with reference to FIGS. 1 and 3 is used, and almost the same processing operation as that of the fifth embodiment described above is performed. The difference of the sixth embodiment from the fifth embodiment is that the encryption setting information received and read in step S36 and the encryption program received and installed in steps S37 and S38 are stored in the encryption processing unit 30. Is written and stored.

  The medical information data is encrypted and transmitted by using the encryption setting information and the encryption program of the receiving destination written and stored in the encryption processing unit 30. Thereby, the same effect as the above-mentioned 5th Embodiment is acquired.

  In the above-described embodiment of the present invention, the case where medical information data is transmitted from the in-hospital signal processing device 11 of the hospital 10 to the out-of-hospital signal processing device 15 has been described as an example. Medical information data may be transmitted to the signal processing device 11. In this case, the function built in the in-hospital signal processing device 11 can be realized by providing the out-of-hospital signal processing device 15.
