  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing an overall configuration of a medical information acquisition system S according to the first embodiment. The medical information acquisition system S includes a medical workstation 1, a hospital room terminal 2, a portable information terminal 3, and a storage medium 4 with a communication function connected to the hospital room terminal 2.

The medical workstation 1 and the hospital room terminal 2 are connected to each other via a communication network N. Further, a database 5 is also connected to the communication network N. The medical workstation 1 and the database 5 constituting the medical information acquisition system S include, for example, a hospital information management system (HIS), a radiation department information management system (RIS), and a medical image management. All or some of various management systems built in a medical institution such as a system (PACS: Picture Archiving Communication System) may be configured.

  In the block diagram showing the overall configuration of the medical information acquisition system S in FIG. 1, the medical workstation 1 and the database 5 are included in a frame indicated by a broken line, and the frame indicates the above-described various management systems.

  The management system A includes a medical workstation 1A and a database 5A. On the other hand, the management system B includes a medical workstation 1B and a database 5B. FIG. 1 shows an example in which two management systems A and B are connected to the communication network N. However, how many management systems (and the medical workstation 1 and the database 5 as constituent elements) are included. It may be connected to the communication network N.

  The medical workstation 1 is stored in the database 5, for example, various information such as name and patient ID, such as patient information (hereinafter referred to as “patient information”), patient medical records, and examination information including medical images and reports. Based on the medical information, information required by the round doctor for the round trip (hereinafter, such information is represented as “round trip data”) is generated. The round trip data is generated based on the latest information every round. Therefore, even for the same inpatient, a round visit is performed by a round doctor under new round data for each round. In addition, an access code used when acquiring the roundabout data or various medical information not included in the roundabout data via the portable information terminal 3 possessed by the roundabout doctor is also generated. The access code is also generated as a different access code every day in the same way that roundabout data is generated based on the latest information each time. This is for ensuring security. A detailed internal configuration of the medical workstation 1 will be described later.

  The hospital room terminal 2 is a terminal for exchanging medical information required for round-trips with the portable information terminal 3 possessed by the doctor. Therefore, these hospital room terminals 2 are installed in the vicinity of a hospital room such as a hospital room or a corridor connecting a hospital room and a hospital room. A storage medium 4 with a communication function is connected to the hospital room terminal 2. Therefore, as will be described later, the hospital room terminal 2 determines whether or not to transmit the medical information stored in the storage medium 4 with the communication function to the portable information terminal 3.

  In addition, although the hospital room terminal 2 is connected to the communication network N shown in FIG. 1 (the hospital room terminal 2A and the hospital room terminal 2B), the hospital room terminal 2 connected to the communication network N is considered in view of the installation location. The number can be set arbitrarily. The detailed internal configuration of the hospital room terminal 2 will be described later.

  The portable information terminal 3 is a terminal that is held and used by a round doctor during a round. Since it is a terminal carried at the time of a round visit, for example, a tablet-type terminal such as iPad (registered trademark), a notebook personal computer, or the like is assumed. On the display unit of the portable information terminal 3, various medical information necessary for the round doctor during the round is appropriately arranged and displayed. The detailed internal configuration of the portable information terminal 3 will be described later.

  Although the storage medium 4 with a communication function is basically a storage medium, a storage function to which information stored in the storage medium can be wirelessly transmitted to other terminals and devices is added. It is a medium. The storage medium 4 with a communication function may be in the form of a card such as “Eye-fi (registered trademark)” or “Wi-fi (registered trademark)” or a shape such as a USB memory. good.

The storage medium 4 with a communication function in the embodiment of the present invention is connected to the hospital room terminal 2 and is stored so that the round trip data generated in the medical workstation 1 is in time for the round of the day. Then, after confirming that the portable information terminal 3 possessed by the round doctor who has entered the hospital room for the round visit has entered the communication range, the hospital room terminal 2 determines the round trip data to the portable information terminal 3.

  The communication network N connects the medical workstation 1, the hospital room terminal 2, and the database 5, and enables, for example, exchange of medical image information between them. Examples of the communication network N include a network such as a LAN (Local Area Network) and the Internet. The communication standard used in the communication network N may be any standard such as DICOM (Digital Imaging and Communication in Medicine).

  FIG. 2 is a block diagram illustrating an internal configuration of the medical workstation 1 according to the first embodiment. In the medical workstation 1, a central processing unit (CPU) 1a, a read only memory (ROM) 1b, a random access memory (RAM) 1c, and an input / output interface 1d are connected via a bus 1e. An input unit 1f, a display unit 1g, a communication control unit 1h, a storage unit 1i, and a removable disk 1j are connected to the input / output interface 1d. Furthermore, the data generation unit 10, the time measuring unit 20, and the erasing unit 30 are connected to the input / output interface 1d.

  The CPU 1a reads and executes a boot program for starting the medical workstation 1 from the ROM 1b based on an input signal from the input unit 1f, and reads various operating systems stored in the storage unit 1i. The CPU 1a controls various devices based on input signals from other external devices not shown in FIG. 2 via the input unit 1f and the input / output interface 1d. Further, the CPU 1a reads out the program and data stored in the RAM 1c, the storage unit 1i, etc., loads them into the RAM 1c, and processes and data for generating round trip data based on the program commands read out from the RAM 1c. It is a processing device that realizes a series of processes such as calculation and processing.

  The input unit 1f includes an input device such as a keyboard and a dial for an operator (for example, a doctor or a laboratory technician) of the medical workstation 1 to input various operations. An input signal is input based on the operation of the operator. It is created and transmitted to the CPU 1a via the bus 1e.

  The display unit 1g is a liquid crystal display, for example. The display unit 1g receives an output signal from the CPU 1a via the bus 1e and, for example, an image necessary for setting a condition when a processing request for a certain image is made to the medical workstation 1, or a processing result of the CPU 1a. Is displayed.

  The communication control unit 1h is a means such as a LAN card or a modem, and is a means that enables the medical workstation 1 to be connected to a communication network N such as the Internet or a LAN. Data transmitted / received to / from the communication network via the communication control unit 1h is transmitted / received to / from the CPU 1a via the input / output interface 1d and the bus 1e as an input signal or an output signal.

  The storage unit 1i is composed of a semiconductor or a magnetic disk, and stores programs and data executed by the CPU 1a.

  The removable disk 1j is an optical disk or a flexible disk, and signals read and written by the disk drive are transmitted to and received from the CPU 1a via the input / output interface 1d and the bus 1e.

  The data generation unit 10 generates round trip data to be presented to the round doctor during the round trip. Information that is the basis for generating round-trip data is various types of medical information such as patient information, patient charts, and examination information. The data generation unit 10 searches and acquires necessary medical information from the database 5 in the management system, and generates round trip data. As described above, the data generation unit 10 generates round trip data based on the latest medical information every round.

  Here, “roundabout data” is data obtained by adding examination data link information and an access code to the latest examination data and medical chart information. The “examination data link information” is link information for accessing other examination data that is not included in the roundabout data generated by the data generation unit 10. An “access code” is a code required when accessing the other inspection data.

  Since the “rounding data” is data (information) disclosed to the round doctor at the round, if too much medical information is generated as round data, the portable information terminal 3 possessed by the round doctor It may take time to receive and may reduce the efficiency of the round trip. Therefore, here, the medical information included in the round trip data is limited to “examination data” and “medical chart information”.

  However, on the other hand, if it is assumed that the round doctor cannot contact other than this information, the information necessary for the round cannot be obtained. Therefore, in the embodiment of the present invention, the examination data link information and the access code are also included in the round trip data and disclosed to the round doctor in advance, so that such adverse effects are prevented, and other medical information is provided. Can access the medical workstation 1 as necessary using an access code or the like.

  In addition, what kind of medical information is configured as roundabout data can be arbitrarily set. In addition, although there is basically no difference in information disclosed to the round doctor, it is possible to give various variations to the round trip data for each round doctor or for each department.

  The timekeeping unit 20 and the erasing unit 30 are used when the generated round-trip data is erased. That is, the medical workstation 1 obtains necessary information from the database 5 and generates round trip data based on these information. However, it is not preferable to keep the generated round trip data in the medical workstation 1 from the viewpoint of security or the capacity of the storage unit 1i. Therefore, the timer 20 measures a preset time, and after the set time has elapsed, the eraser 30 erases the roundabout data.

  FIG. 3 is a block diagram showing an internal configuration of the hospital room terminal 2 and the storage medium 4 with a communication function in the first embodiment. Here, the hospital room terminal 2 is a portable computer such as a notebook computer. Accordingly, the basic internal configuration of the hospital room terminal 2 also overlaps with the internal configuration of the medical workstation 1 described above. Therefore, the description of such each part is omitted.

  In the hospital room terminal 2, a CPU (Central Processing Unit) 2a, a ROM (Read Only Memory) 2b, a RAM (Random Access Memory) 2c, and an input / output interface 2d are connected via a bus 2e. An input unit 2f, a display unit 2g, a communication control unit 2h, a storage unit 2i, and a removable disk 2j are connected to the input / output interface 2d. Further, a data control unit 11, a timekeeping unit 21, and a round trip data erasing unit 31 are connected to the input / output interface 2d.

  For example, the data control unit 11 determines whether or not to transmit the roundabout data stored in the storage unit of the storage medium 4 with communication function to be described later to the portable information terminal 3 possessed by the round doctor. Further, when the roundabout data generated in the medical workstation 1 is transmitted to the hospital room terminal 2, control is performed so that the data is stored in the storage unit 4 of the storage medium 4 with the communication function instead of the storage unit 2 i of the hospital room terminal 2.

  The timekeeping unit 21 and the round trip data erasing unit 31 are used when erasing round trip data from the hospital room terminal 2 regardless of whether or not there is transmission to the portable information terminal 3. That is, the hospital room terminal 2 sends the roundabout data received from the medical workstation 1 to the roundabout doctor who has entered the hospital room after a predetermined procedure, that is, the portable information terminal 3 that has entered the communication area of the storage medium 4 with communication function. To send round trip data. Since the storage medium 4 with a communication function has a function of transmitting the round trip data generated in the medical workstation 1 to the portable information terminal 3, the round trip data is kept indefinitely after transmission. Is not preferable from the viewpoint of security or from the viewpoint of the capacity of the storage unit of the storage medium 4 with communication function. Therefore, the timer 21 measures a preset time, and after the set time has elapsed, the round data deletion unit 31 erases the round data.

  The storage medium 4 with a communication function includes a first transmission / reception unit 41 that exchanges control signals with the data control unit 11 of the hospital room terminal 2, and a storage unit that stores round-trip data transmitted to the portable information terminal 3. 42 and a second transmission / reception unit 43 that exchanges information wirelessly with the portable information terminal 3. In the storage unit 42 of the storage medium 4 with communication function, information such as patient information, personal digital assistant information, and a round schedule is included in addition to the round data.

  Patient information is information relating to inpatients. The information is acquired by a medical institution as information when hospitalization is determined, for example. Therefore, for example, it is good also as storing in the memory | storage part 42 of the said storage medium 4 with a communication function in that case. The storage unit 42 also stores information related to the round schedule. The round-trip schedule is a schedule that defines the round-trip schedule for each room and each patient in the round doctor. The information related to the round trip schedule is a schedule created each time a round trip is performed, and is created by, for example, a separate management system. In addition, when there is a change in the round schedule, the change is reflected as needed. The information related to the round schedule is one piece of information necessary when the hospital room terminal 2 determines whether or not it is possible to transmit the round trip data to a doctor who has the portable information terminal 3 that has entered the hospital room.

  Furthermore, information regarding the portable information terminal 3 is also stored. The information related to the portable information terminal 3 is information related to the portable information terminal 3 possessed by the round doctor visiting the hospital room for the round visit. In addition, when the round doctor and the portable information terminal 3 are in a one-to-one correspondence, the information about the portable information terminal 3 can be regarded as information about the round doctor. This information is also one piece of information required when the hospital room terminal 2 determines whether or not it is possible to transmit round trip data to a doctor who has the portable information terminal 3 that has entered the hospital room.

  FIG. 4 is a block diagram showing an internal configuration of the portable information terminal 3 in the first embodiment. Here, the portable information terminal 3 is a tablet-type terminal, for example, as described above. Therefore, the basic internal configuration of the portable information terminal 3 also overlaps with the internal configuration of the medical workstation 1 described above. Therefore, the description of such each part is omitted.

In the portable information terminal 3, a CPU (Central Processing Unit) 3a, a ROM (Read Only Memory) 3b, a RAM (Random Access Memory) 3c, and an input / output interface 3d are connected via a bus 3e. An input unit 3f, a display unit 3g, a communication control unit 3h, a storage unit 3i, and a removable disk 3j are connected to the input / output interface 3d. Further, a timer unit 22 and a received data erasing unit 32 are connected to the input / output interface 3d.

  The storage unit 3 i of the portable information terminal 3 stores roundabout data generated in the medical workstation 1 and transmitted from the storage medium 4 with communication function. A round doctor holding the portable information terminal 3 performs a round while confirming the round trip data stored in the storage unit 3i. In addition, since the round doctor will be possessed during the round, for example, the input unit 3f may be configured as a touch panel type input unit, for example.

  The timer unit 22 and the received data erasing unit 32 are used when erasing the roundabout data from the portable information terminal 3. That is, the portable information terminal 3 acquires the roundabout data from the storage medium 4 with a communication function and uses it for the roundabout by the roundabout doctor. However, the roundabout data must be deleted under certain restrictions. This is because the portable information terminal 3 is carried around by the round doctor, so that it is not necessary to delete the roundabout data in the storage unit 3i from the viewpoint of security or the portable information terminal 3 This is not preferable from the viewpoint of the capacity of the storage unit 3i. Therefore, the timer 22 measures a preset time, and after the set time has elapsed, the received data eraser 32 erases the roundabout data.

  Next, the sequence from the generation of round trip data used when the round doctor performs the round trip to the erasure of the round trip data used after the round trip is completed will be described with reference to the sequence diagrams shown in FIGS. I will explain. FIG. 5 to FIG. 8 are sequence diagrams showing a flow from the generation of roundabout data to the portable information terminal 3 possessed by the roundabout doctor and deletion in the first embodiment.

  The medical workstation 1 generates round trip data and an access code in the data generation unit 10 (ST1 in FIG. 5). The timing at which the data generation unit 10 generates roundabout data and the like can be arbitrarily set. For example, the roundtable schedule is established and the contents of the roundtable schedule can be grasped. For example, since information about patients who have already been hospitalized has been obtained (registered), the next day's round schedule can be generated after information about patients who are newly hospitalized has been registered. Conceivable. Accordingly, after the round trip schedule is generated, the medical workstation 1 generates the round trip data and the access code by obtaining information on the round trip schedule.

  On the other hand, when the round trip schedule is generated, information regarding the round trip schedule is automatically transmitted to the hospital room terminal 2 in the hospital room in which the inpatient is a target of the round trip, and the storage unit of the storage medium 4 with communication function 42 is stored. Furthermore, in addition to information related to the round schedule, the data control unit 11 stores information related to the portable information terminal 3 and patient information.

  The information related to the portable information terminal 3 is information related to the portable information terminal 3 possessed by the round doctor as described above, in other words, information related to the round doctor who holds the portable information terminal 3. The medical information acquisition system S is a system that provides medical information necessary for round visits generated as round trip data from the storage medium 4 with communication function to the round doctor (portable information terminal 3). The round-trip data is one of the most confidential personal information, and handling thereof requires strict attention. Therefore, it is not always possible to provide such round trip data to any person who has the portable information terminal 3, and it is necessary to confirm the destination. Therefore, information about the portable information terminal 3 is stored in the storage unit 42 in advance, and round trip data is transmitted only to the portable information terminal 3 that matches the information.

In addition, it is also possible to authenticate the round doctor who possesses the portable information terminal 3 directly without using the information related to the portable information terminal 3 to confirm the portable information terminal 3. For example, by using a method in which the round doctor inputs his / her doctor ID into the hospital room terminal 2 or causes the hospital room terminal 2 to read a card storing the information possessed by the doctor ID, the round doctor Can be authenticated. However, in this case, it takes more time than the hospital room terminal 2 automatically confirms.

  Patient information is information about a patient who is hospitalized in a hospital room in which the hospital room terminal 2 is installed or a hospital room in the vicinity thereof. The information is updated, for example, every time an examination, a medical examination, or the like is performed, or whenever an inpatient is replaced.

  The hospital room terminal 2 confirms the round-trip schedule (information on the round trip schedule) from the storage medium 4 with communication function in which various information as described above is stored (ST2). This confirms from what time and in what order round-trips are performed for a patient admitted to a hospital room in which the hospital room terminal 2 is installed or a hospital room in the vicinity thereof. Then, a request for obtaining round trip data that matches the round trip schedule is issued to the medical workstation 1 (ST3).

  Upon receiving the round trip data acquisition request from the hospital room terminal 2, the medical workstation 1 transmits the generated round trip data and the access code to the hospital room terminal 2 that issued the request (ST4). Further, the sent roundabout data and access code are erased by the erasing unit 30 (ST5).

  In this case, the medical workstation 1 erases the round trip data and the like by using the round trip data and the access code transmitted to the hospital room terminal 2 as a trigger. However, for example, the timekeeping unit 20 starts measuring a predetermined time when the roundabout data is transmitted to the hospital room terminal 2, and the erasure unit 30 erases the roundabout data and the like after a predetermined time has elapsed. Also good.

  The hospital room terminal 2 acquires the roundabout data and the access code transmitted from the medical workstation 1 (ST6). Upon receipt of the roundabout data and the access code, the data control unit 11 of the hospital room terminal 2 generates a roundabout data flag (ST7). This rounding data flag clarifies that rounding data or the like that matches the rounding schedule has been received from the medical workstation 1.

  The hospital room terminal 2 stands by in this state. That is, the mobile information terminal 3 possessed by the round doctor enters the communication area of the storage medium 4 with communication function connected to the hospital room terminal 2 and waits until communication is possible (ST8). Actually, whether or not the data control unit 11 recognizes the portable information terminal 3 that can communicate through the second transmission / reception unit 43 of the storage medium 4 with communication function is a standby state. (NO in ST8).

  When the data control unit 11 recognizes the communicable portable information terminal 3 (YES in ST8), the data control unit 11 transmits the roundabout data and the access code to the recognized portable information terminal 3 ( Disclosure) Consider the conditions for judging whether or not Here, from the side of the portable information terminal 3 possessed by the round doctor, the portable information terminal 3 has entered the communication area of the storage medium 4 with communication function of the hospital room terminal 2 (ST9). .

  First, information regarding the recognized portable information terminal 3 is confirmed (ST10). In the storage unit 42 of the communication function-equipped storage medium 4, information on the portable information terminal 3 possessed by the round doctor visiting the hospital room in which the hospital room terminal 2 is installed or a hospital room in the vicinity thereof is held. Stored. Therefore, the stored information on the portable information terminal 3 and the information on the portable information terminal 3 recognized by the data control unit 11 are compared.

  Next, the data control unit 11 confirms the round-trip schedule stored in the storage unit 42 of the storage medium 4 with communication function (ST11). That is, the round schedule of the day in the hospital room where the hospital room terminal 2 is installed or in the hospital room in the vicinity thereof is confirmed. By confirming this round trip schedule, it is possible to avoid sending round trip data to a portable information terminal possessed when a doctor in charge of the round trip visits a hospital room regardless of the round trip.

  Furthermore, the data control unit 11 confirms whether or not the corresponding roundabout data has been transmitted from the medical workstation 1 (ST12). In order to prevent the occurrence of a situation in which some trouble occurs during transmission of roundabout data from the medical workstation 1 to the hospital room terminal 2 and no roundabout data is stored in the storage medium 4 with communication function. It is.

  Here, the data control unit 11 sequentially checks the information about the recognized portable information terminal 3, the information about the round schedule, and the presence / absence of round trip data, but the order of these checks should be set arbitrarily. Can do. Alternatively, these confirmations may be performed in parallel.

  Then, the relationship between these three pieces of information is confirmed (ST13 in FIG. 6). Even if each piece of information is correct, it is considered that it is not appropriate when it is considered as information about rounds on a specific day. Therefore, here, it is confirmed whether or not the relationship between the three pieces of information is appropriate as information relating to today's rounds disclosed to round doctors. If the association is appropriate, the data control unit 11 determines that the roundabout data can be disclosed to the portable information terminal 3 (YES in ST14). The case where it is determined that the round-trip data cannot be disclosed (NO in ST14) will be described later.

  The data control unit 11 generates an information reading sign used when the portable information terminal 3 reads the roundabout data (ST15). In the “information reading sign”, for example, information related to the hospital room terminal 2, information related to the storage location of roundabout data, patient information, and an access code are stored. The portable information terminal 3 receives this information reading sign (ST17) and analyzes it (ST18), thereby obtaining round trip data required by the round doctor.

  The reason why the information reading sign is first generated and transmitted without immediately transmitting the roundabout data directly to the portable information terminal 3 is as follows. That is, in the embodiment of the present invention, as will be described later, the medical information required other than the round-trip data requires a separate process for acquisition. As a previous step, roundabout data is transmitted to the portable information terminal 3. However, when medical information with a large amount of information is collectively transmitted to the portable information terminal 3, it takes time to receive. Therefore, the acquisition of medical information is divided into two stages, and round trip data generated with a small amount of information is first transmitted to the portable information terminal 3.

  On the other hand, the roundabout data is composed of various information as described above, and the amount of information is small as an absolute amount, and it is difficult to say that it is light information. Accordingly, if such round trip data is transmitted to the portable information terminal 3 from the beginning, it takes a long time to receive the data, and the roundabout doctor cannot wait for the round trip during that time. This reduces the efficiency of the rounds.

  So, if you first send an information reading sign and receive the roundabout data of the corresponding patient as the roundabout progresses, you can get roundabout data about other patients while going round one patient It is possible to avoid wasteful rounds.

Examples of the “information reading sign” include a barcode (regardless of the number of dimensions). Further, the information reading sign is managed, for example, in the storage unit 2i of the hospital room terminal 2.

  Based on the information (access code) of the information reading sign analyzed in the portable information terminal 3, the portable information terminal 3 makes a request for obtaining round trip data required by the round doctor to the hospital room terminal 2 (ST19). . Upon receiving the acquisition request, the hospital room terminal 2 wirelessly transmits the roundabout data stored in the storage medium 4 with communication function to the portable information terminal 3 (ST20). For example, a general transfer protocol such as http is used for transmission of roundabout data from the storage medium 4 with communication function to the portable information terminal 3.

  The portable information terminal 3 acquires roundabout data transmitted from the storage medium 4 with communication function connected to the hospital room terminal 2 (ST21). In addition, with this, the timing unit 22 starts timing (see ST22 in FIG. 7). The reason for starting the time measurement here is to use it for determining whether to delete the roundabout data acquired by the portable information terminal 3. Then, the acquired round trip data is displayed on the display unit 3g (ST23). In addition, the order of the start of time measurement and the display of the roundabout data may be the order described here, or may be the order of display and time measurement, or the processing may be performed in parallel. .

  In the hospital room terminal 2, when the roundabout data is transmitted to the portable information terminal 3, the timekeeping unit 21 starts timekeeping (ST24). The time is measured here because it is used to determine the erasure of the roundabout data stored in the storage medium 4 with the communication function and transmitted to the portable information terminal 3. Further, the rounding data flag generated when the rounding data is acquired is changed to already transferred here (ST25).

  As described above, information (rounding data) necessary for the portable information terminal 3 possessed by the round doctor is acquired and displayed. The round doctor uses the round trip data when he / she visits a patient admitted to the hospital room. In addition, patient information is also included in the information reading sign, so it will be used as a reference during rounds.

  When the round doctor is making a round trip, depending on the inpatient, the acquired round trip data may not be sufficient, and other information may be referred to (ST26). In this case, the round doctor uses the access code and the examination data link information both included in the round trip data to request the hospital room terminal 2 to acquire other information (ST27). The data control unit 11 of the hospital room terminal 2 receives the request, and further requests the medical workstation 1 to acquire other information (ST28).

  In the medical workstation 1, the data generation unit 10 searches and acquires information corresponding to the acquisition request in the database 5, and transmits it to the hospital room terminal 2 (ST29). Further, other transmitted information is deleted here (ST30).

  The hospital room terminal 2 acquires other information transmitted from the medical workstation 1 and transmits it to the portable information terminal 3 (ST31). The data control unit 11 generates a roundabout data flag regarding the acquired other information (ST32), and starts counting again (ST33). If other information acquired later is deleted after a predetermined time that is one of the conditions for deleting the data for the first visit and then deleted, the time to refer to the other information of the round doctor is reduced. This is also possible. After that, it is assumed that the roundabout data flag related to the generated other information has been transferred (ST34).

  The portable information terminal 3 obtains other information and displays the other information on the display unit 3g (ST35). Then, the timing in the timing unit 22 is started again (ST36).

  Next, with reference to FIG. 8, the flow of erasing data for round trips present in the hospital room terminal 2 (storage medium 4 with communication function) or the portable information terminal 3 after the round trip by the round doctor is completed will be described. The reason for erasing the round trip data is to keep the round trip data used indefinitely, so that it does not leak in any way and it is safe from the viewpoint of security. Here, the flow of erasure in the hospital room terminal 2 (storage medium 4 with communication function) and the portable information terminal 3 will be described separately. This is because information is not exchanged between these devices in the erasing flow.

  First, the flow of erasing the roundabout data held in the portable information terminal 3 will be described. When the round doctor completes the round, the usual round doctor leaves the room where the round was performed. The hospital room terminal 2 is installed in a hospital room or a place (such as a hallway) in the vicinity of the hospital room. Accordingly, the communication area of the storage medium 4 with communication function connected to the hospital room terminal 2 is the hospital room or the vicinity of the hospital room. Therefore, when the round doctor finishes the round and leaves the room and moves, the portable information terminal 3 is out of the communication range of the storage medium 4 with the communication function by leaving a certain distance from the room. In such a state, it is considered that the roundabout data held in the portable information terminal 3 may be deleted. Therefore, portable information terminal 3 determines whether or not storage medium 4 with a communication function is located outside the communication range (ST41).

  When it is determined that the portable information terminal 3 is outside the communication range of the storage medium 4 with communication function (YES in ST41), it is further determined whether or not a predetermined time has passed (ST42). The “predetermined time” is the time measured from the time when the roundabout data is received in the time measuring unit 22 of the portable information terminal 3.

  Here, it is judged that the predetermined time has elapsed, and when the portable information terminal 3 is located outside the communication range of the storage medium 4 with communication function, the roundabout data is not deleted immediately. However, the possibility of returning and restarting the round is taken into consideration. When resuming the round trip, it takes time to obtain the roundabout data once acquired from the hospital room terminal 2 again. In some cases, the roundabout data stored in the storage unit 42 of the storage medium 4 with communication function may also be deleted. In this case, it takes more time. Therefore, even if the portable information terminal 3 is located outside the communication range, the erasing data is erased further waiting for a predetermined time.

  After that, when a predetermined time has passed (YES in ST42), the roundabout data received and held is deleted (ST43). With the above flow, the erasure of the roundabout data held in the portable information terminal 3 is completed.

  Next, the erasing data stored in the storage unit 42 of the storage medium 4 with communication function connected to the hospital room terminal 2 will be described. First, the data control unit 11 confirms whether the roundabout data flag has been transferred (ST51).

When the roundabout data stored in the storage unit 42 is transmitted to the portable information terminal 3, the roundabout data flag generated by obtaining the roundabout data transitions to transferred. On the other hand, the roundabout data may not be transmitted to the portable information terminal 3 for some reason. For example, as described above, when the storage medium 4 with communication function transmits the roundabout data to the portable information terminal 3, there is information that constitutes three conditions, and these three relationships are necessary. If any of the conditions is not met, the roundabout data is not disclosed (NO in ST14 in FIG. 6). In such a case, the roundabout data flag does not transition to the transferred state and remains in the generated state. In addition, for example, when the information required by the round doctor does not need to acquire enough data for round trips only by analyzing the information reading sign, the round trip data flag is also used. Does not transition to already transferred.

  As described above, the roundabout data flag may or may not transition to the transferred state. If the transfer has been completed (YES in ST51), the data control unit 11 determines whether or not a predetermined time has passed (ST52). This “predetermined time” is a time measured from the time when the rounding data is acquired by the time measuring unit 21. Since the round trip data is transmitted to the portable information terminal 3 and the round trip to the hospital room is one of the treatments usually performed in medical institutions, the portable information possessed by the round doctor after the round trip data is generally acquired. The time from the transmission to the terminal 3 until the completion of the round is a time that can be grasped. Therefore, by setting such a time as a preset time for timekeeping, it is possible to operate the roundabout data that can ensure the security while making use of the roundabout data at the roundabout. If the predetermined time has not elapsed (NO in ST52), the process returns to the flow of determination as to whether or not the roundabout data flag has already been transferred.

  On the other hand, if the predetermined time has elapsed (YES in ST52), it is further determined whether or not all rounds set in the round schedule have been completed (ST53). As described above, the round schedule is a basic schedule for the round doctor to go around the hospital room in which the target patient is hospitalized, and the round is performed according to the schedule. Therefore, the data control unit 11 confirms the round schedule and determines whether or not the round schedule for the day is complete. If the round trip schedule is not completed (NO in ST53), the round trip is still in progress, so if the roundabout data is deleted, it corresponds to the case where a re-acquisition request is transmitted from the portable information terminal 3. It becomes impossible to do. Therefore, in this case, the deletion is not performed, and the flow of deletion including the presence / absence of completion of the round trip schedule is determined again.

  On the other hand, when it is determined that the round schedule has been completed (YES in ST53), the data control unit 11 receives the round trip data stored in the storage unit 42 of the storage medium 4 with communication function. Is deleted (ST54).

  By performing such erasure processing for the portable information terminal 3 and the hospital room terminal 2, it is possible to ensure security without leakage of roundabout data.

  As described above, it is necessary for the round doctor to go around the hospital room by adopting a mechanism that wirelessly transmits the round trip data to the personal digital assistant owned by the round doctor using the storage medium 4 with communication function. Therefore, it is possible to provide a medical information acquisition system and a medical information acquisition method in which the roundabout efficiency is improved by acquiring simple medical information in a simple and reliable manner and the security of the acquired medical information is sufficiently considered.

  In particular, nurses can send round trip data generated by medical workstations to portable information terminals owned by round doctors via a storage medium with communication functions connected to terminals installed in hospital rooms. It is possible to save the labor and burden of preparing and clearing medical charts and the like that are necessary for round trips in advance. In addition, the efficiency of rounds can be improved.

  In the above, roundabout data is generated and transferred using a general protocol. For example, roundabout data is converted and generated as RAW data in a medical workstation, and a storage medium with a communication function is generated. It is also possible to transmit to a portable information terminal via. In this case, the portable information terminal that has received the roundabout data as RAW data converts it into data that can be read and displayed by the portable information terminal and displays it.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the second embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description of the same components is omitted because it is duplicated.

  In the second embodiment, when various systems such as a management system are not built in a medical institution, a mechanism for wirelessly transmitting necessary medical information to various places using a storage medium with a communication function explain.

  FIG. 9 is a block diagram illustrating an overall configuration of the medical information acquisition system S2 according to the second embodiment. The medical information acquisition system S2 includes a medical image diagnostic apparatus 51 that acquires internal information of a patient, a medical workstation 52 that wirelessly receives internal information as medical information from the medical image diagnostic apparatus 51, and a wireless communication from the medical image diagnostic apparatus 51. The mobile information terminal 53 that receives medical information and the medical image diagnostic apparatus are connected to the medical image diagnostic apparatus, store at least the medical information, and when the mobile information terminal enters a communicable area, the medical information is wirelessly transmitted to the mobile information terminal. It is comprised from the storage medium 54 with a communication function to transmit.

  The medical image diagnostic apparatus 51 is an apparatus that collects information inside a patient, images the inside of the subject based on the collected information, and generates a medical image. Examples of the medical image diagnostic apparatus 51 include an X-ray CT apparatus (computed tomography) and a magnetic resonance imaging apparatus (MRI).

  The medical image diagnostic apparatus 51 here is an apparatus such as a general X-ray CT apparatus, and there is nothing particularly new in configuration except that a storage medium 54 with a communication function described later is connected. A description of the internal configuration is omitted.

  Further, a storage medium 54 with a communication function is connected to the medical image diagnostic apparatus 51. The storage medium 54 with a communication function here is the same as the storage medium 4 with a communication function in the first embodiment described above. Therefore, since the configuration and function are the same, detailed description is omitted here. The difference is that, in the first embodiment, it is connected to the hospital room terminal 2, but in the second embodiment, it is connected to the medical image diagnostic apparatus 51. Accordingly, the medical image diagnostic apparatus 51 stores the internal patient information acquired by the medical image diagnostic apparatus 51 stored in the storage medium 54 with communication function as medical information in the medical workstation 52 or the portable information terminal 53. It plays the role of transmitting wirelessly.

  The medical workstation 52 is a kind of information terminal connected to the database 55 and serving as one part of various management systems. The internal configuration of the medical workstation 52 is as described with reference to FIG. The medical workstation 52 and the database 55 are connected to each other via a wired communication network N1.

  Note that some medical workstations 52 may not be able to handle DICOM standard data in that format. In this case, the medical workstation 52 may be equipped with a function (or application) for converting medical information transmitted from the medical image diagnostic apparatus 51 into information of DICOM standard.

In other words, in the embodiment of the present invention, the medical information (rounding data) is transferred from the medical image diagnostic apparatus 51 using the storage medium 54 with a communication function. Therefore, there is a possibility that the roundabout data to be transferred does not comply with the DICOM standard. In this state, the medical workstation 52 cannot see the roundabout data sent. Therefore, a conversion function (application) is used to make these pieces of information comply with the DICOM standard. By using the conversion function (application), the medical workstation 52 can also view and view information according to the DICOM standard.

  At this time, as a procedure, roundabout data that does not conform to the DICOM standard received at the medical workstation 52 is once converted into roundabout data that conforms to the DICOM standard and then registered in the database 55, and then the database 55 The data for round-trips registered in (the round-trip data is already round-trip data in accordance with the DICOM standard) are browsed.

  The portable information terminal 53 is a terminal that the round doctor has when visiting the hospital room, and the internal configuration thereof is as described with reference to FIG.

  In addition, in the case of a device including an application that can handle DICOM standard data in its format, including the portable information terminal 53, the transmitted information that does not conform to the DICOM standard is opened and viewed. be able to.

  In the second embodiment, the above-described configuration is adopted. By adopting such a configuration, even if it is difficult to construct a wired network environment in the hospital, such as an emerging country or a small medical institution, a storage medium with a communication function By using a system that wirelessly transmits round trip data to the portable information terminal possessed by the round doctor by using 4, the medical information necessary for the round doctor to go round the hospital room can be easily and reliably acquired. Thus, it is possible to provide a medical information acquisition system and a medical information acquisition method that improve the efficiency of round trips and sufficiently consider the security of the acquired medical information.

  In addition, by adopting this configuration, it is possible to construct a very inexpensive and simple network transfer environment without using a storage medium (media) as an object, so that medical information can be exchanged smoothly between devices. It becomes possible to do.

  Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
