Description

  The present invention relates to a medical information management system and medical equipment for managing medical information of a patient in a medical facility.

  In the medical facility, an electronic medical chart apparatus is provided for managing medical information (patient condition, medical practice, examination data, etc.) of the patient. In this case, as disclosed in Patent Document 1, a blood glucose meter (medical device) used by a medical worker can be communicated with an electronic medical chart device, whereby measurement data such as a blood sugar level can be transferred to the electronic medical chart device. It can be easily memorized. Medical devices are not limited to blood glucose meters, but include various medical devices for ward examination (POCT: Point Of Care Testing) for bilirubin, malignant tumors, infectious diseases, etc. Medical measuring instruments such as thermometers, blood pressure monitors, pulse oximeters, etc. Furthermore, this type of medical device includes a self blood glucose meter (SMBG device), a portable electrocardiograph, a female thermometer, and the like, which are devices that are used daily by a patient and are brought into a medical facility for diagnosis.

  Unlike a large analyzer that is installed in a laboratory and the inspection process after transporting the test sample is performed in a separate room, the POCT device performs a series of operations up to the test and measurement value confirmation in the vicinity of the patient. Can be quickly reflected in treatment. Therefore, in addition to the bedside, it contributes to quick inspections in emergency outpatients, OPE rooms, dialysis rooms, etc. In addition, the POCT device is compact in size so that it can be easily carried, and is configured to be able to identify medical workers and patients such as doctors and nurses, thereby improving work efficiency, safety, and medical economics.

JP 2004-555 A

  By the way, in a system in which a medical device (POCT device, medical measuring device, etc.) and an electronic medical record device (computer) communicate information, the specification change (improvement, version upgrade, etc.) of one device is performed. Communication failure may occur because the device does not comply with the specification. For example, even if a new standard medical device is adopted from the current medical device, if the electronic medical record device remains as it is, the electronic medical record device misrecognizes and receives the medical information transmitted from the medical device as abnormal information. There is a risk that problems such as disabling will occur. Therefore, even if the medical device can greatly improve the measurement accuracy due to the improvement, the communication specification on the medical device side will change, and if it cannot be applied to the current electronic medical chart device, it can be sold. Often not adopted. In addition, the adoption of new standard medical devices will be implemented step by step while confirming their operability and safety by replacing some of the current products we own not only in terms of cost but also in terms of safety. In many cases, current products and new-standard medical devices are mixed in the same medical facility. In recent years, further improvement in the measurement accuracy of the POCT instrument is expected to improve the therapeutic effect in the long term, but the inconvenience that the improved characteristics will not be used due to the market characteristics becoming an obstacle, Such a barrier has created a vicious circle in which device improvement activities are delayed.

  In addition, in a situation where multiple specifications are mixed in both medical devices and electronic medical chart devices in this way, in order to avoid information communication failures, improved medical devices are also included in the current electronic medical chart device standards. It is also possible to configure such that the communication mode can be set and the communication mode corresponding to the electronic medical chart apparatus is set by the user's setting operation (that is, matched to the current standard). However, in such a configuration that requires the user to change the setting, problems such as the user forgetting the setting method, making a setting mistake, making the setting operation bothersome, or being misused as it is and being unable to transmit and manage medical information are likely to occur. In particular, it is likely to cause confusion at a medical site where a plurality of medical devices may be used in parallel or a plurality of types of medical devices may be replaced.

  A medical information management system 10 according to an embodiment of the present invention is provided in a medical facility as a system (so-called electronic medical record system) that processes and stores medical information of a patient C and manages the medical information in an integrated manner. It is configured. As shown in FIG. 1, the medical information management system 10 includes a medical device 12 and a computer 16 that constructs an electronic medical chart device 14.

  As the medical device 12, an information processing device capable of information communication with medical information is applied to the computer 16. The medical device 12 includes an input / output interface, a processor, and a memory (both not shown), and the processor executes a predetermined program to process medical information and store the processed medical information in the memory. To do.

  As the medical device 12, a medical measurement device (for example, a blood glucose meter 20, a sphygmomanometer 22, a thermometer 24 shown in FIG. 1, or a pulse oximeter (not shown), a urine test apparatus, Biochemical test analyzers, immunoassays, etc.) can be applied. This type of medical device 12 is configured so that an internal program cannot be simply rewritten in order to suppress errors during examination and diagnosis and maintain reliability. The medical device 12 is not limited to those used for medical examinations and diagnoses, and various devices that can handle medical information and can transmit and receive medical information to and from the electronic medical chart device 14 may be applied.

  In addition, the medical device 12 can be configured as a POCT device used by a medical worker (user) U such as a doctor or a nurse mainly in a medical facility. The POCT device has a function of identifying the patient C and the medical staff U and recording and calling up measurement data (medical information) for each patient C. Further, the POCT device may have a function of managing medical information in association with the patient C, the medical worker U, the measurement date and time, the treatment action, and the accuracy confirmation record in conjunction with the tool of the medical information management system 10.

  If this medical device 12 is a medium-scale or large-scale medical facility, a plurality of types of devices (for example, a blood glucose meter 20, a sphygmomanometer 22, a thermometer 24) are prepared, and a plurality of the same types (for example, , The number corresponding to the number of medical workers and the number of patients). The plurality of medical devices 12 are stored in an appropriate storage location 104 such as the nurse station 100 or a warehouse. Of course, the medical information management system 10 can also be configured with one type and one medical device 12.

  The computer 16 constitutes a main system that manages medical information of the patient C handled at the medical facility. The computer 16 includes a main body 16a, a monitor 16b, and an input device 16c (keyboard, mouse, etc.), and a known device having hardware such as an input / output interface, a processor, and a memory (both not shown) in the main body 16a. Can be applied.

  For example, a plurality of computers 16 are provided in a medical facility, and one or more client terminals 26 and one or more server terminals 28 constitute an electronic medical chart apparatus 14 of a client server model. In addition, the medical information management system 10 may configure the electronic medical chart apparatus 14 by connecting a plurality of computers 16 to each other by a peer-to-peer model. Further, the computer 16 can function as the electronic medical chart device 14 even if only one computer 16 is provided in the medical facility.

  The client terminal 26 is a terminal used by the medical worker U during work, and is installed, for example, for each nurse station 100 of the medical department that the medical facility has. The client terminal 26 operates the electronic medical chart application 30 (hereinafter referred to as the electronic medical chart application 30) by the processor executing and processing a client-side program (not shown) based on the operation of the medical staff U.

  The electronic medical record application 30 exchanges information with the server terminal 28 via the network (LAN 32) installed in the medical facility under the operation of the medical staff U, and the electronic provided by the server terminal 28 It has a function of accessing the database of the chart service 34. In this case, the electronic medical chart application 30 can perform various types of medical information processing according to the authority of the medical worker U according to the identification ID of the medical worker U who operates. In addition, the electronic medical record application 30 relays between the medical device 12 and the server terminal 28 to acquire medical information of the medical device 12 and store it in the database of the electronic medical record service 34.

  A reader / writer device 36 (reading unit) that performs information communication with the medical device 12 is connected to the input / output interface of the client terminal 26 by wire or wirelessly. Inside the reader / writer device 36, a communication module (not shown) that performs communication according to a known communication standard is provided.

  The communication standard is not particularly limited, and wired communication and short-range wireless communication can be used. In short-range wireless communication, non-contact communication standards using infrared communication such as IrDA (Infrared Data Association), NFC (Near Field Communication) devices including FeliCa (registered trademark), etc. may be applied. Alternatively, the communication standard for short-range wireless communication is a standard having a slightly longer communication distance such as DSRC (Dedicated Short Range Communication), Bluetooth (registered trademark), communication conforming to the IEEE 802.11x standard (including WiFi), and the like. Also good. The distance between the reader / writer device 36 and the input / output interface at the time of communication is set as appropriate with a distance within 20 cm as an approach state, within 10 m as a short distance communication, and approximately 10 to 100 m as a relatively long distance.

  Further, these communication functions may be provided in a holding structure for the medical device 12, a connection device such as a charging stand, a case, and a strap. Further, the communication timing may be programmed at a regular time, communication may be started by a user's transmission operation, or automatic communication may be performed whenever data is updated.

  The medical information management system 10 according to the present embodiment uses the communication standard of FeliCa (registered trademark), and the medical device 12 includes an IC chip for communicating with the reader / writer device 36. Then, when the medical worker U brings the medical device 12 close to the communication surface of the reader / writer device 36, the medical information possessed by the medical device 12 can be transmitted to the client terminal 26. The medical information may be automatically transmitted in the execution state of the electronic medical chart application 30 of the client terminal 26, or may be transmitted based on the medical worker U performing a data reading operation on the electronic medical chart application 30.

  When the medical information of the medical device 12 is transmitted to the client terminal 26, a communication mode common to the client terminal 26 and the medical device 12 is used. The communication mode of the medical information management system 10 is provided with dedicated security to prevent unauthorized access and tampering, and restricts other devices that are not registered or devices that are not in common communication mode from communicating with each other. To do. This communication mode adopting the non-contact communication standard has predetermined communication commands (command packet CP, response packet RP). The medical information of the medical device 12 is provided to the client terminal 26 by transmitting and receiving a communication command a plurality of times while the client terminal 26 and the medical device 12 are in proximity.

  Hereinafter, for convenience of explanation, the communication mode of the medical device 12 is also referred to as a medical device side communication mode M, and the communication mode of the electronic medical chart application 30 is also referred to as a medical chart side communication mode CM. It can be said that the medical device side communication mode M and the medical chart side communication mode CM share communication commands so that they can be transmitted and received in a state where medical information can be communicated.

  More specifically, the client terminal 26 and the medical device 12 are in the same communication mode (medical device side communication mode M, medical chart side communication mode CM) as shown in FIG. To establish a wireless connection. The specified command packet CP and response packet RP are sequentially repeated to transmit / receive information.

  For example, in FIG. 2, the client terminal 26 (reader / writer device 36) transmits a command packet CP 1 including device capture to the medical device 12. As a result, the medical device 12 returns a response packet RP1 including the terminal ID to the client terminal 26 to perform authentication on the client terminal 26 side.

  If the medical device 12 is authenticated, the client terminal 26 then transmits a command packet CP2 for reading the measurement data (medical information) to the medical device 12. Upon receiving this read request, the medical device 12 returns a response packet RP2 including the stored medical information to the client terminal 26. The medical information at this time is associated with the identification ID of the patient C, the identification ID of the medical worker U who performed the measurement, the identification ID of the chip 21 used in the medical device 12, and the like. The client terminal 26 stores the medical information in the database of the server terminal 28 in a form appropriately processed using the electronic medical chart application 30.

  When the transmission of medical information from the medical device 12 is completed, finally, the client terminal 26 transmits a command packet CP3 including device release to the medical device 12. As a result, the medical device 12 returns a response packet RP3 including a reply (ACK) that has accepted the end of communication to the client terminal 26, and ends the communication.

  The above exchange of communication commands is automatically performed based on the construction of one wireless connection (the approach state between the client terminal 26 and the medical device 12). Hereinafter, when medical information is communicated, communication commands transmitted and received mutually are collectively referred to as a command group 38.

  Returning to FIG. 1, the server terminal 28 is installed in, for example, the server room 102 of the medical facility, and constitutes a host computer of the medical information management system 10 that comprehensively manages information handled in the medical facility. The server terminal 28 has a server-side program (not shown) that performs the electronic medical record service 34 of the electronic medical record apparatus 14, and regularly executes the program. The server terminal 28 provides medical information from the database of the electronic medical record service 34 in response to a request from the client terminal 26 (electronic medical chart application 30) connected to the LAN, and changes or additions of medical information in the database. Perform deletion.

  In a medical facility in which the medical information management system 10 described above is provided, a medical worker U regularly uses the medical device 12 to perform rounds (round trips, patrols). For example, as shown in FIG. 1, a medical worker U possesses a blood glucose meter 20 that is a POCT device stored in a nurse station 100, travels to a plurality of hospital rooms HR in a ward, and receives blood glucose of a plurality of patients C. Measure the value.

  In using the blood glucose meter 20 in a ward, first, the medical worker U is authenticated by reading the identification ID of the medical worker U into the blood glucose meter 20. The blood glucose meter 20 has a barcode reader (not shown), and reads the identification ID by reading the barcode individually assigned to the medical staff U. Similarly, using the blood glucose meter 20, the medical worker U reads the identification ID of the patient C for each patient C in the hospital room HR, authenticates the patient C, and further determines the lot (chip ID) of the chip 21 to be used. read. And the medical worker U measures the blood glucose level of the patient C who read identification ID using the blood glucose meter 20 with which the chip | tip 21 was mounted | worn. The reading of the identification ID and the chip ID of the patient C and the measurement of the blood glucose level are repeated for each patient C, and further repeated while changing the room HR. The blood glucose meter 20 may be configured to omit reading the identification ID and chip ID of the medical worker U according to the setting of the medical information management system 10 and the content of the round.

  After completing the measurement of the blood glucose level in the ward, the medical worker U returns to the nurse station 100 and holds the used blood glucose meter 20 over the communication surface of the reader / writer device 36 of the client terminal 26. Thereby, the blood glucose level measurement data (medical information) stored in the blood glucose meter 20 is read by the electronic medical chart application 30 of the client terminal 26 by wireless communication. Then, the electronic medical record application 30 stores the blood glucose level measurement data in the database of the electronic medical record service 34 of the server terminal 28. As described above, in the measurement data, the identification ID of the patient C, the identification ID of the medical worker U, the chip ID, and the like are associated with each other and stored. Thereafter, the medical worker U stores the blood glucose meter 20 whose measurement data has been read by placing it on a charging stand or the like of the storage location 104.

  In addition, the round of a medical facility is not limited to the measurement of the blood glucose meter 20, and various measurement data are acquired by using various medical devices 12 for the patient C who needs measurement. The medical information management system 10 accumulates the measurement data obtained by the medical device 12 in the round as described above in a database managed by the electronic medical record service 34, so that it can be used for the treatment of the patient C.

  Here, when performing information communication of medical information between the medical device 12 and the electronic medical chart device 14 (client terminal 26, server terminal 28), as described above, the mutual communication mode (medical device side communication mode M, The medical chart communication mode CM) must be common. However, for example, when the blood glucose meter 20 (also referred to as the current product 20A) in the conventional measurement range is replaced with a blood glucose meter 20 (hereinafter also referred to as the improved product 20B) whose blood glucose level measurement range has been widened by the improvement, the improvement is made. It is necessary to perform communication in the new medical device side communication mode M2 (see FIG. 3) corresponding to the product 20B. Therefore, it is desirable that the electronic medical chart apparatus 14 also performs version upgrade (improvement) according to the improved product 20B.

  If the electronic medical chart device 14 is not upgraded, the old medical chart communication mode CM1 corresponding only to the current product 20A is maintained, and the improved product 20B has only the new medical device communication mode M2; There is a possibility that uploading of medical information or normal recognition of data cannot be performed from the product 20B. For example, when the measurable range of the improved product 20B is expanded due to version upgrade, even if the electronic medical chart device 14 is communicable, the measurement data of high blood glucose level is judged as abnormal measurement on the electronic medical chart service 34 side and excluded. , Such as not reflected in the database.

  However, depending on the medical facility, there are cases where it is determined that the version of the electronic medical chart apparatus 14 is not upgraded immediately in view of the cost, labor, risk, etc. in the improvement. Therefore, the improved product 20B is configured to have a new medical device side communication mode M2 corresponding to the improved product 20B and an old medical device side communication mode M1 corresponding to the current product 20A. As a result, when the version of the electronic medical chart apparatus 14 remains the current, the improved product 20B transmits medical information to the electronic medical chart apparatus 14 by setting the old medical device side communication mode M1 according to the version. It becomes possible.

  The medical information management system 10 according to the present embodiment identifies the mutual communication mode (version) at the time of information communication between the electronic medical chart device 14 and the medical device 12, so that the common medical device communication mode M and the medical record The side communication mode CM is set automatically. Hereinafter, with reference to FIG. 3 and FIG. 4, the structure of the electronic medical chart apparatus 14 and the medical device 12 which implement | achieve this function is demonstrated.

  The electronic medical chart apparatus 14 (client terminal 26) constructs the medical chart side control unit 40 that implements the electronic medical chart application 30 by the processor reading and executing the client side program stored in the memory. The chart side control unit 40 includes a chart side mode transmission unit 42, a chart side mode acquisition unit 44, a chart side mode setting unit 46, and a chart side communication control unit 48 as functional units that perform information communication with the medical device 12.

  The chart side mode transmission unit 42 transmits information related to the chart side communication mode CM of the electronic chart apparatus 14 to the medical device 12 as a mode advance notification AN. That is, before the medical information management system 10 transmits / receives the command group 38 between the electronic medical chart device 14 and the medical device 12, the medical information management system 10 first sets the medical chart side communication mode CM based on the version of the electronic medical record app 30 to the medical device 12. It is configured to inform. For example, at the timing when the reader / writer device 36 detects the approach of the medical device 12, the chart side mode transmission unit 42 first transmits a mode advance notification AN related to the latest version of the chart side communication mode CM of the electronic chart application 30. .

  The chart side mode acquisition unit 44 acquires information (response notification RN) related to the medical device side communication mode M transmitted from the medical device 12. Thereby, the electronic medical chart apparatus 14 can recognize the version of the medical device side communication mode M of the medical device 12.

  The chart side mode setting unit 46 sets a chart side communication mode CM that is common to the version of the medical device side communication mode M acquired by the chart side mode acquiring unit 44. The chart side mode setting unit 46 stores one or more chart side communication modes CM in a chart side data storage unit 46a formed in a memory, and performs medical information communication mode when communicating medical information. The chart side communication mode CM corresponding to M is set from the chart side data storage unit 46a.

  The chart side communication control unit 48 constructs a wireless connection environment with the medical device 12 by using the chart side communication mode CM set by the chart side mode setting unit 46. Then, as shown in FIG. 2, medical information is acquired by exchanging a command group 38 (transmitting a command packet CP to the medical device 12 and receiving a response packet RP from the medical device 12). The medical chart side control unit 40 appropriately processes the acquired medical information and stores the medical information in the database of the electronic medical record service 34 of the server terminal 28.

  On the other hand, the medical device 12 constructs the medical device-side control unit 50 that uploads medical information to the electronic medical chart application 30 by reading and executing the medical device-side program stored in the memory by the internal processor. The medical device side control unit 50 is a medical device side mode acquisition unit 52 (notification acquisition unit), a medical device side mode setting unit 54, and a medical device side mode transmission unit 56 as functional units that perform information communication with the electronic medical chart apparatus 14. And a medical device side communication control unit 58.

  The medical device side mode acquisition unit 52 acquires the mode advance notification AN transmitted from the chart side mode transmission unit 42. Thereby, the medical device 12 can recognize the version of the medical chart side communication mode CM (electronic medical chart application 30) of the electronic medical chart apparatus 14.

  The medical device side mode setting unit 54 sets the medical device side communication mode M that is common to the version of the medical chart side communication mode CM acquired by the medical device side mode acquisition unit 52. The medical device side mode setting unit 54 stores one or more medical device side communication modes M in the medical device side data storage unit 54a of the memory, and corresponds to the electronic medical chart apparatus 14 when performing communication of medical information. The medical device side communication mode M to be set is set from the medical device side data storage unit 54a.

  The medical device side mode transmission unit 56 returns information related to the medical device side communication mode M to the electronic medical chart apparatus 14 as a response notification RN. The response notification RN of the medical device 12 is transmitted to the electronic medical record device 14 including its own medical device communication mode M based on the mode advance notification AN previously acquired from the electronic medical record device 14.

  The medical device side communication control unit 58 uses the medical device side communication mode M set by the medical device side mode setting unit 54 to construct a wireless connection environment with the electronic medical chart apparatus 14. In addition, the medical device side communication control unit 58 receives the command packet CP from the electronic medical chart device 14 and thereby transmits a response packet RP including medical information.

  The medical information management system 10 and the medical device 12 according to the present embodiment are basically configured as described above, and their operational effects will be described below.

  In the operating state of the medical information management system 10, as shown in FIG. 1, the medical staff U measures the patient C with the medical device 12 (blood glucose meter 20) in a round or the like, and acquires measurement data. After the round, the medical staff U brings the medical device 12 close to the reader / writer device 36 of the electronic medical chart device 14 (client terminal 26) in order to store the acquired measurement data in the electronic medical record service 34. As a result, the electronic medical chart device 14 and the medical device 12 are wirelessly connected to enable information communication.

  When the information communication is enabled, the chart side mode transmission unit 42 of the electronic medical chart apparatus 14 first transmits a command packet CP of the mode advance notification AN of the chart side communication mode CM corresponding to the latest version of the electronic medical chart apparatus 14 itself. . For example, as shown in FIG. 4, when the electronic medical chart device 14 is the current version (Ver. 1) of the electronic medical chart application 30A, the old communication mode advance notification AN1 is transmitted to the medical device 12.
