JP4508590B2 - Subject confirmation system and medical image diagnostic apparatus - Google Patents

Description

  The present invention relates to a patient confirmation system that performs processing such as registration and management of patient information in hospitals and instructions for examination order, and in particular, the collection of a subject when calling a subject who is waiting for medical care or examination. It relates to technology to prevent mistakes.

In recent years, medical accidents such as subject misunderstandings and drug administration mistakes have been reported in medical practice, and medical accident countermeasures have become an important issue to be addressed first by medical personnel.
As a cause of occurrence of this subject misplacement, for example,
(R-1) Medical workers engaged in diagnosis (doctors, radiologists, technicians, nurses, etc.) must always view a large number of unspecified subjects in parallel.
(R-2) The work of medical personnel is fragmented and cannot be accompanied by one subject from the beginning to the end.
(R-3) The introduction of advanced subject management methods is costly, so subject management is left to health care professionals.
Can be given.

  This problem is presently indispensable as a medical diagnostic means, such as an X-ray diagnostic apparatus, an X-ray CT apparatus, a magnetic resonance imaging apparatus (hereinafter referred to as an MRI apparatus), an ultrasonic diagnostic apparatus, etc. This is also the case with medical image diagnostic apparatuses of the above-mentioned, and the possibility of a medical accident such as a mistake in the subject is inherently inherent. For example, if a subject is mistaken in imaging using a contrast medium, there is a possibility that the imaging corresponding to the contraindication of the contrast medium may be performed on the subject, which is very dangerous. Therefore, it is necessary to take measures against medical accidents in the medical image diagnostic apparatus.

  As a technique for preventing the subject from being mixed, there is a technique described in [Patent Document 1], for example. In this technique, a display device is provided in the vicinity of a medical image diagnostic apparatus to display a subject name. As a result, the name of the subject can be confirmed by the subject himself / herself who is going to be examined or treated, or by the attendant who has been accompanied by the subject. To prevent.

In addition, a means for extracting at least the subject name from the subject information set in the medical image diagnostic apparatus by the medical staff is provided, and the subject name is displayed on the display device. As a result, the display of the name of the subject on the display device is routinely displayed based on the subject information set in the medical image diagnostic device, so that the subject is not troubled by the medical staff. To prevent misunderstandings.
JP 2003-52641 A

  The subject's first and last name is displayed on the display device from the subject information set in the medical diagnostic imaging apparatus by the medical staff, and the subject himself / her attendant confirms it [Patent Document 1] In the technique, the confirmation work by the subject himself is performed on a routine basis. However, when multiple similar subjects with the same information are waiting for an examination, the subject is mistakenly identified as his / her own order even though the displayed information is small and cannot be identified. There is a possibility of receiving.

  For example, there are the following cases. That is, it is assumed that two people A and B having the same name and the same name are to be photographed by the medical image diagnostic apparatus on the same day. A was the first to accept photography, and B was also accepted. Both of them were waiting for the shooting order in the waiting room, but after A took off the seat because A was required, B entered the examination room according to the name called by the health care worker and was displayed on the MRI machine By confirming the name of the subject, we confirmed the subject's misunderstanding and took a picture. This is an example in which a medical worker was looking at the imaging slip after a while and noticed that there was a subject with the same name, and the date of birth was confirmed, so that the difference in the subject was found.

In other words, if a subject with the same surname receives a photograph on the same day, the subject name may be displayed on the display device, and even if the subject can confirm the subject himself / herself, a difference in the subject may occur. This is not sufficient as a measure to prevent the subject from being mixed.
On the other hand, for medical professionals, the subject confirmation work that should be performed originally becomes quiet due to the reasons (R-1) to (R-3) described above and depends only on the subject's uncertain confirmation work. There is a possibility. In the worst case, the examination is performed without any subject confirmation by the medical staff.

  Accordingly, an object of the present invention is to provide at least a medical staff at the time of subject information registration or medical treatment / examination when there are a plurality of similar subjects with the same surname or the same surname in the same day or in the past photographing / medical history. A test that can inform the existence of a plurality of similar subjects with one and the same subject information, prompt the medical staff to confirm the subject, and provide identification information for identifying the subject It is to realize a person confirmation system.

In order to achieve the above object, the present invention is configured as follows. That is,
In the subject confirmation system having means for inputting subject information, means for storing subject information, and means for displaying information of subjects waiting for examination,
The subject information input means obtains the subject information stored in the subject information storage means and confirms the presence or absence of a similar subject having at least one identical subject information; and Means for generating warning information corresponding to the similarity of the similar subject,
The examination waiting subject information display means includes means for displaying the subject information and the warning information of the examination waiting subject.
Thereby, when there are a plurality of similar subjects having at least one same subject information, the presence of a plurality of similar subjects is notified to the medical staff at the time of subject information registration or medical treatment / examination, Since it is possible to prompt the medical staff to confirm the subject, it is possible to prevent the subject from being mistaken.

  According to the present invention, when there are a plurality of similar subjects having the same family name or the same family name in the same day or in the past photographing / medical history, at least one medical staff is registered at the time of subject information registration or at the time of medical treatment / examination. A test confirmation that informs the health care professional of identification of the subject by reporting the presence of multiple similar subjects with the same subject information and providing identification information to identify the subject A person recognition system can be realized.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment of the invention, and the repetitive description thereof is omitted.
A first embodiment of a subject confirmation system to which the present invention is applied will be described. FIG. 1 shows a block diagram of a first embodiment of a subject confirmation system to which the present invention is applied. In the first embodiment, a plurality of distributed subsystems are interconnected by a network to form a subject confirmation system, and subject information and the like are transmitted and received between the subsystems. A medium-sized or larger hospital with network infrastructure is assumed.

  In FIG. 1, 101 is a subject information input system disposed at a hospital reception, for example, 102 is a host computer or server (hereinafter simply referred to as a server) that manages and controls the entire subject confirmation system, 103-105 Is a medical department subsystem that manages a subject placed in an examination room or medical examination room equipped with a medical diagnostic imaging device, 106 is an information network (LAN) that connects the subsystems, 107 is the above A branch LAN connecting the subsystems 103 to 105 and the information network 106, 108 to 110 are databases (hereinafter referred to as DB) for storing and managing subject information and the like via the server 102, and 108 receives medical care or examination. A daily subject information DB for storing and managing the individual identification information of the subject every day, 109 is a total subject information DB for storing and managing all the subject information, 110 The test according to various warning levels Warning message or template for medical personnel such as operators and receptionists / doctors / nurses / operators of medical diagnostic imaging devices, and warning messages storing information items that can identify the subject at the warning level DB.

Hereinafter, each subsystem will be described in detail.
FIG. 2 shows an embodiment of a table configuration and items such as subject specific information stored and managed in the DB.

[Table: Registered subjects] is a table for storing and managing various types of subject information for identifying registered subjects. Both the daily subject information DB 108 and the total subject information DB 109 Created on. For example, the following items are registered using the subject ID as a primary key. However, the following items are typical items, and more subject information is actually stored, but is omitted here.
(1-1) Subject ID: ID number (primary key) that uniquely identifies the subject. It is automatically issued at the time of new registration.
(1-2) Surname: Subject's surname (1-3) First name: Subject's first name (1-4) Date of birth: Subject's birth date, Subject's age based on this value Is calculated.
(1-5) TEL: Subject's phone number (1-6) Social insurance number: Subject's social insurance number

In the example of FIG. 2, surname = Hitachi, first name = Hanako, date of birth = 1966.07.01 (the age is calculated to be 37 years old as of August 10, 2003), etc. are registered in the subject ID = M01232201 Has been.
[Table: Examination History] is a table for storing and managing the medical treatment / examination history of each subject, and is created in both the daily subject information DB 108 and the all subject information DB 109. In this table, at the time of actual medical treatment / examination, whether or not there is a similar subject and the warning ID indicating the warning message corresponding to the similar contents, and whether the subject himself / herself is the subject of medical treatment / examination Whether or not the medical staff has confirmed the subject or not is memorized so that a later third party can easily check. For example, the following items are registered using the subject ID as a primary key. However, the following items are representative items and are not limited to these.

(2-1) Subject ID: ID number (primary key) that uniquely identifies the subject
(2-2) Date and time of reception: Date and time of reception of medical examination (2-3) Department of medical treatment: Name of medical department that received medical examination (2-4) Examination item: Type of medical diagnostic equipment under examination (2-5) Subject confirmation: Whether or not the subject himself / herself was confirmed to be medical care / tested (the date and time of confirmation may be registered)
(2-6) Health care worker confirmation: Whether the health care worker in charge has confirmed the subject (the date and time of confirmation may be registered)
(2-7) Warning ID: Foreign key to the warning message stored in [Table: Warning message] (described below)

  In the example of Fig. 2, the subject = Hanako Hitachi (ID = M01232201) was undergoing an MRI examination at 10:10 on September 10, 2003, with a warning ID = 3 (described below) Therefore, there was another subject with the same name and the same name on the day, and further confirmation was made because the subject confirmation = completed and the health care worker confirmed = completed. It has been recorded.

  [Table: Warning message] is a table storing various warning messages to be shown to the subject and the medical staff, and is stored and managed in the warning message DB 110. This table is a subject information item that makes it possible to identify a warning level corresponding to the presence or absence of a similar subject or the same subject information item between similar subjects, a warning message in that case, and a similar subject. Names are prepared in advance, and in the table for storing and managing them, for example, the following items are registered using the warning ID as a primary key. However, the following items are representative items and are not limited thereto.

(3-1) Warning ID: ID number (primary key) that uniquely identifies the warning message
(3-2) Warning level: Warning level corresponding to the presence or absence of similar subjects and similar contents (3-3) Identification item: Subject information item name that enables identification of similar subjects with this warning ID (3-4) Message for examinee: Warning message or template to be displayed to the subject (3-5) Message for person in charge: Warning message to be displayed for medical staff or template thereof

  In the example of FIG. 2, there is no problem with the record with warning ID = 0, and there is no need to display a warning message. The record with warning ID = 1 indicates that the surname of the subject matches and the warning level is 1, and a warning message is displayed to the effect that the subject with the same surname exists for the subject and the healthcare worker In this case, for example, it is only necessary to identify similar subjects by name, so that the identification item = name. In addition, the record with warning ID = 2 is a warning message that there is a subject with the same name for the subject and the medical worker when the name of the subject matches and the warning level = 1. In this case, for example, the similar item can be identified by the last name, so that the identification item = last name. In addition, the record with warning ID = 3 is when the surname and the surname of the subject match, the alert level = 2, and there is a subject with the same surname for the subject and the medical staff In this case, for example, it is sufficient to identify similar subjects by age, so that the identification item = age.

  Of the above three types of tables, [Table: Registered subjects] and [Table: Examination history] are created in both the daily subject information DB 108 and the total subject information DB 109, and the data is stored and managed. Is done. The various table contents in the daily patient information DB 108 are DBs for registering and managing the daily examinee subjects. The data registered the previous day is deleted every day and the table contents are reset to empty (zero). Is done. On the other hand, in the all subject information DB 109, data is sequentially accumulated and updated in each table stored and managed therein, and each table is not reset to empty (zero). If a new subject is registered, the subject information of the new subject is registered simultaneously in both the daily subject information DB 108 and the total subject information DB 109, but all the subject information has already been registered. If registered in the DB 109, when the subject is accepted, the registration data in the all subject information DB 109 is copied to the daily subject information DB 108, and if necessary, in both DBs New information is added or updated to the subject information. However, only the contents of [table: registered subject] may be copied.

  In addition, when [Table: Registered subjects] and [Table: Examination history] are created together for the entire hospital, subject management is performed collectively for the entire hospital. If these two tables are created separately, it becomes subject management for each department. The present invention can be applied to any case, and the method of creating a table may be changed according to the purpose of subject management.

  In the above description, the DB is managed separately for each day and the entire DB. However, only the entire subject information DB 109 may be configured. The advantage of dividing the DB into two parts, daily and overall, is that a similar subject limited to only one subject per day can be searched at high speed. However, if this advantage is not taken seriously, as a configuration of only the entire subject information DB 109, the similar subject limited to only the subject of one day is also searched for the entire subject information DB 109, It is possible to determine whether the date is the date of the reception date. As a result, there is an advantage that DB management / operation becomes easy. Alternatively, if only the presence / absence of similar subjects in a day is considered as a warning target without considering past similar subjects, only the daily subject information DB 108 may be used. Any method may be adopted in consideration of the system operating conditions.

  Next, the server 102 that manages and controls the entire subject confirmation system will be described. The server 102 allocates data transmitted from each subsystem (client) via the information network 106 to various DBs, stores the data or updates the old data with the data, and responds to the request of each subsystem. The obtained data is read from various DBs and transmitted to the subsystem via the information network 106. Further, if the program for inputting, updating, browsing, etc. of the subject information is executed on the server 102 and each subsystem performs only its (GUI) display and data input / output, the server 102 From each subsystem, display information and various data are transmitted, and from each subsystem, response information of the operator to the display and various input data are transmitted to the server 102. Alternatively, if the program is executed on each subsystem, the server 102 transmits the program and various data to each subsystem, and the program is executed on each subsystem. Various data input during the execution of this program is transmitted to The present invention is applicable to any of the above systems or any other possible system.

  Next, the subject information input system 101 and the subject registration procedure in this subsystem will be described. FIG. 3 shows an embodiment of the registration screen of the subject information input system 101. The subject information input system 101 includes a display means for displaying a registration screen 401 (Japanese version) or 601 (English version), an input means such as a keyboard and a mouse, a storage means for storing a program, and an information network. And a control means for controlling them. However, FIG. 3 shows only the registration screen, and the others are omitted. FIG. 3 (a) is an example of a Japanese subject registration screen 401, and FIG. 3 (b) is an English display 601 thereof. Since there is a difference between Japanese and English in the representation of first and last names, the display order of first and last names is reversed. In this embodiment, a subject's surname input field 402, a name input field 403, a subject ID input field 404, a birth date input field 405, a telephone number input field 406, and a social insurance number input field 407 are provided. Can be registered, but is not limited thereto. Further, the configuration of each input field on the screen is not limited to FIG.

FIG. 4 shows a registration process flow at the time of subject information registration based on the Japanese registration screen 401. Hereinafter, the registration procedure will be described with reference to the flowchart of FIG.
Registration of subject information follows the display on the subject registration screen 401, and the person in charge of reception (medical worker) uses the keyboard or mouse based on the subject's personal information described on the insurance card, medical questionnaire, etc. Make input. Then, the DB is searched for whether or not there is a similar subject having the same information as the input subject information. At that time, if there is a similar subject with the same information in the daily subject information DB, it means that there is a similar subject on the same day, and there is no subject information DB in the daily subject information DB If a similar subject exists only in the DB, it means that there was a similar subject in the past. The warning information is selected corresponding to whether the similar subject exists on the same day or the past, and the result is registered in the DB together with the subject information. Specifically:

If you are already registered,
(S-1) Since the subject ID has already been issued, enter the subject ID.
(S-2) The entire subject information DB is searched from the entered subject ID, the subject information having the subject ID is acquired, and is copied to the daily subject information DB. However, only the contents of [table: registered subject] may be copied.
(S-3) The daily subject information DB and the total subject information DB are checked to determine whether there are other subjects having the same information for each subject information item.
(S-4) If there are other subjects with the same information, turn on the input field of the same information item, select the warning information corresponding to the degree of coincidence and the same day or the past, and Register the warning ID in [Table: Examination History]. This warning ID is based on [Table: Warning Message] in FIG. 2, for example, when there are other subjects with the same surname in the daily subject information DB, warning ID = 1, and all subjects If there are other subjects with the same surname only in the information DB, warning ID = 4. In addition, when the input field for the same information item is lit, at the time of registration, the person in charge of reception recognizes that there is a subject having the same information in the subject on the same day or in the past.
(S-5) If there are no other subjects with the same information, there will be no similar subjects, and the warning ID = 0 is registered in [Table: Examination History].

  On the other hand, if the subject is a new subject, or if there is no subject ID, the subject having the same information is searched by searching the DB for each item entered by entering subject information. Check if it exists elsewhere. Although the input can be performed from any of the input items in FIG. 3, a case of inputting from a surname will be described in the present embodiment.

(S-6) Enter the subject's surname in the surname input field 402.
(S-7) The daily subject information DB and the entire subject information DB are checked to determine whether there are other subjects with the same surname as the input surname. If not, the process proceeds to (S-9).
(S-8) If there is another subject with the same surname as the last name entered, the surname input field 402 will light up, select the alert information corresponding to the same day or the past, and enter the alert ID Register in [Table: Examination History]. A specific example of the warning ID is the same as in the case of (S-4). By illuminating the last name input field 402, at the time of registration, the person in charge of reception recognizes that there is a subject with the same surname among the subjects on the same day or in the past, and alerts them.
(S-9) Enter the subject name in the name input field 403.
(S-10) Search the daily subject information DB and the total subject information DB to check whether there are other subjects with the same first and last names. If not, the process proceeds to (S-12).

(S-11) If there are other subjects with the same first and last names that have been entered, the last name entry field 402 and the first name entry field 403 light up, and warning information corresponding to the same day or the past is displayed. Select and register the warning ID in [Table: Examination History]. A specific example of the warning ID is the same as in the case of (S-4). By illuminating both the first name input field 402 and the first name input field 403, at the time of registration, the person in charge of reception recognizes that there is a subject with the same name and the same name in the past subject on the same day or in the past.
(S-12) In the same way, enter other items in the same manner, and search the daily patient information DB and the total patient information DB each time, and match the subject information entered so far. If there is a subject in the DB, select the warning information according to the degree of coincidence and whether it is the same day or the past, and enter [Table: Registered subject] together with the entered subject information. sign up. If all the items match, it can be, for example, a registered subject.

  In the above, the example in which the input field is lit as the alerting method in (S-4), (S-8), and (S-11) has been described. However, as another alerting method, the flashing of the input field, Alternatively, for example, a pop-up window 701 displaying a warning message as shown in FIG. 3 may be displayed together with the lighting or blinking of the input field, or only the pop-up window 701 may be displayed. However, in the case of a pop-up window, a pop-up window is displayed each time subject information is input, which may be an annoying function for a receptionist who is always inputting subject information. Therefore, the window display on / off may be set by the person in charge of reception.

  As described above, if the subject is a new subject, the subject ID assigned to the subject and the entered subject information are registered in [Table: Registered subject], and the reception date and time The medical department, examination item, and warning ID to be received by the subject are registered in [Table: Examination History] together with the subject ID. When a plurality of inspection items are required for one subject, the same subject ID is registered in [Table: Inspection History] for each inspection item. When registering in this [table: examination history], the fields of subject confirmation and medical worker confirmation are initialized and registered as, for example, “not yet” (meaning that they have not been confirmed yet).

  Next, an embodiment of the medical department subsystem 103 and subject confirmation in this subsystem will be described with reference to FIG. The medical department subsystem 103 includes display means such as a display for a subject 501 and a display for an operator 502, input means such as a keyboard and a mouse, storage means for storing programs and the like, connection means for an information network, And a control means for controlling them. However, only both displays are shown in FIG. 5, and others are omitted. This medical department subsystem is installed in the examination room where the medical image diagnostic apparatus and its operator (healthcare worker) are waiting, and in the treatment room where doctors and nurses (healthcare workers) are waiting, When a health care worker calls each subject registered in the subject list one by one and performs an examination or medical treatment using a medical diagnostic imaging device, the subject is confirmed with the subject and the health care worker. A warning message or the like is displayed and prompts both to confirm the subject.

  FIG. 5 shows an embodiment in which a medical department subsystem 103 is arranged in an examination room that performs an examination using an MRI apparatus as a medical image diagnostic apparatus to perform subject confirmation. Near the entrance of the laboratory (not shown), a display for the patient to display a warning message to the called patient is placed, and the operator is alerted to the operator along with the patient list. An operator display for displaying a message is arranged to display a warning message or the like.

  This clinical department subsystem obtains a list of subjects to be examined or examined in the clinical room of this clinical department from the daily patient information DB via the information network on the same day, and operators, nurses, etc. The medical staffs sequentially call the subjects according to the subject list and perform medical care or examination. At this time, for the called subject, a warning message for the subject based on the subject name and warning ID can be easily displayed on the display for the subject arranged near the entrance of the clinic or examination room. Display it in your eyes.

  This patient warning message is obtained by accessing the warning message DB and obtaining and displaying the patient warning message from [Table: Warning Message] on the basis of the warning ID, : Warning message], a warning message for the subject is acquired and temporarily stored in the storage unit of the medical department subsystem together with the subject list, and displayed in correspondence with the called subject. In the example of FIG. 5, since there are other subjects with the same name as a warning message, there is a message prompting the health care professional to check. . In response to this, the subject thinks that he / she has to check with the medical staff such as the operator, and confirms himself / herself that he / she is the subject of the examination or examination by answering an inquiry from the operator or the like.

Similarly, for medical personnel such as operators, a warning message for medical personnel corresponding to the warning ID is displayed on the operator's display to encourage the medical personnel to confirm the subject. Yes. In addition, the warning message displayed for the medical staff is also displayed with identifiable information indicating which subject information should be used for confirmation.
This identifiable information is displayed by referring to the identification item of the record specified by the warning ID from [Table: Warning message] in FIG.

  In the example of FIG. 5, because there is another subject with the same name as the subject name, Hanako Hitachi, a warning message for a health care worker with warning ID = 3 (warning level = 2) is displayed, and Since the identification item of warning ID = 3 = age, a message prompting confirmation using age information different from that of a similar subject is also displayed. The health care professional is prompted by such a warning message on the operator display and should confirm, and is called up based on the first and last name and age information also displayed on the operator display. The subject is asked to match his age and first name, and is confirmed to be the subject in the examination order registered in the subject list.

  Since the age information at this time is the identification item = age, access [Table: Registered Subject], obtain the date of birth data of this subject, and determine the age based on the difference from the current date and time. Is calculated and displayed. The method for acquiring the warning message for medical staff, the identification item, and the actual data thereof is the same as the method for acquiring the warning message for the subject.

Further, when the subject confirms that he / she is the subject of the examination, he / she responds to the clinical subsystem by confirming that the subject has confirmed by touching (or pressing) a confirmation button displayed on the display for the subject, for example. . Similarly, the medical staff also responds to the medical department subsystem that the subject has been confirmed by touching (or depressing) a confirmation button displayed on the operator display, for example. The clinical department subsystem writes “completed” in the [Table: Examination History] to confirm that the confirmation has been obtained, and at the time when both confirmations are completed, the MRI apparatus, which is a medical image diagnostic apparatus, can be activated. To do. That is, while neither of the confirmations can be obtained, the medical department subsystem controls the medical image diagnosis apparatus so that it cannot be activated by being locked. If the user tries to start it forcibly, a message prompting the patient to check the subject first and a voice guide to that effect are issued so that the subject is not checked in an unconfirmed state.
Such inspection device locking means is added to the clinical department subsystem as necessary.

  Further, in any display of the warning message for the subject and the warning message for the medical staff, the display method may be changed corresponding to the warning level so that the warning level can be easily recognized by both. . For example, the higher the warning level, the brighter color such as red can be displayed as the background color, and the lower the warning example bell, the calmer color such as light blue can be displayed as the background color.

  The above is an embodiment in which all the configuration requirements in the clinical department subsystem of the present invention are applied, but it is necessary to prepare all the configuration requirements in the clinical department subsystem of the present invention for patient confirmation. In addition, only the warning message display means for the medical staff may be provided, and the warning message display means for the subject and the inspection device lock means may be omitted. In this case, only the medical staff such as the operator performs the above-described subject confirmation based on the warning message for medical staff. Even in such a case, the patient can be confirmed with realistic certainty.

  Next, a second embodiment of the subject confirmation system to which the present invention is applied will be described. This second embodiment is an embodiment in which the functions of each subsystem constituting the subject confirmation system described in the first embodiment are provided in the medical image diagnostic apparatus to confirm the subject, A small hospital with no in-hospital network infrastructure is assumed.

  In the description of the second embodiment, a case where the present invention is applied to an MRI apparatus as a medical image diagnostic apparatus will be described. First, an outline of an MRI apparatus to which the present invention is applied will be described. FIG. 6 is a block diagram of an MRI apparatus to which the present invention is applied.

  In FIG. 6, a subject 2 is placed on a magnet 1 that generates a uniform static magnetic field in an imaging space, and a bed 3 is provided as means for placing the subject 2. Gradient magnetic field coil 4 that adds positional information between the magnet and the imaging space, high-frequency coil 5 that irradiates high-frequency waves to the hydrogen nuclei of subject 2, and nuclear magnetic resonance (hereinafter referred to as nuclear magnetic resonance) generated from subject 2 It has a receiving coil 6 for receiving a signal (referred to as NMR). The NMR signal detected by the receiving coil 6 is converted into an audible frequency signal by the transmission / reception system 7. The NMR signal converted into the audio frequency signal is converted into a digital signal by the AD converter 8. The NMR signal converted into a digital signal by the AD converter is subjected to necessary processing by the apparatus control unit 9 and reconstructed into an image. A gradient magnetic field for applying position information necessary for imaging is applied by the gradient magnetic field power source 10 controlled by the apparatus control unit 9 and the gradient magnetic field coil 4 connected to the gradient magnetic field power source. The device control unit 9 includes an operation unit 11 for an operator (medical worker) to operate imaging conditions, device information, patient information, and a display 12 for displaying an operation screen, a captured image, and the like. ing.

  FIG. 7 shows a block diagram of the configuration of the part related to the subject information registration in the MRI apparatus of FIG. In FIG. 7, the device control unit 9 includes a CPU 201 that performs calculation and device control, a DB 202 for storing device information, subject information, and captured images, an operation screen, and a display 12 for displaying captured images. The operation unit 11 is provided for the operator to operate. In this DB 202, the above-mentioned daily subject information DB 108, all subject information DB 109 and warning message DB 110 are created, and each table of FIG. 2 is created in the daily subject information DB 108 and all subject information DB 109. Thus, it is managed and operated by the CPU 201.

  The flow of inspection applied to the MRI apparatus is shown in FIG. As for the flow of the examination, a medical worker registers the subject information in the MRI apparatus based on a medical record, a reservation slip, an imaging slip, etc. (301). Next, the operator calls the subject waiting for the examination order in the waiting room or the like into the examination room (302). The called subject enters the examination room and photographing is performed (303). According to the present invention, at the time of registration of the subject information (301), the operator is notified that a similar subject having the same surname or the same surname exists in a waiting room or the like in the same day or past photography. Prompt for confirmation of the subject by telling the operator, and when the subject is called into the laboratory (302), the subject identification information is directly inquired and confirmed to the subject to prevent the mistake. .

  Next, registration means for subject information registration (301) in the second embodiment will be described. The subject information input screen is the same as in FIG. 3, and will be described with reference to the registration process flow at the time of subject information registration in FIG. The registration of the subject information is performed using the operation unit 11 on the subject registration screen 401 displayed on the display 12. Since the configuration of the subject registration screen 401 is assumed to be different depending on various apparatuses, the arrangement of the input items and the registration contents may be any configuration. In this embodiment, as shown in FIG. 3, the subject name input field 402, the name input field 403, the subject ID input field 404, the date of birth input field 405, the telephone number input field 406, the social insurance number input A field 407 is provided for registering such information. Registration of the subject information is performed by the person in charge (medical worker) using the operation unit 11 based on a medical record, a reservation slip, a photographing slip, and the like. The registration process flow is as follows.

(T-1) Enter the surname or first name of the surname of the subject. In this embodiment, a case where a surname is input first will be described. However, as shown in Fig. 3, in the English version of the Patient Registration screen (Patient Registration) 601, the placement of the First Name (name input field) 603 and Last Name (last name input field) 602 is the Japanese version of the patient registration. It is conceivable that the first name 603 is input first in reverse to the arrangement on the screen 401. Therefore, either the first name or the last name input order registered by the operator may be first, so the comparison between the information in the subject information input field and the DB 202 is completed in the last name input field 402 and the last name (last name input field) 602. At this point, the comparison is started. If they do not match, move to (T-3) or (T-9).

(T-2) When the surname input in the surname input field 402 matches the subject surname information recorded in the DB 202, the surname input field 402 is lit. When the input field 402 is lit, the medical staff is informed that there is a subject with the same surname among the subjects to be photographed on the same day. As a result, for example, when the subject is called into the examination room, confirmation is made to the subject such as calling the full name where the name is usually called only by the surname.

(T-3) The subject name is entered in the name entry field 403. However, if the name is entered first, it has already been entered. Here, if the last name of the subject that was performed earlier does not exist on the same day, the presence of the same name on the subject registration screen 401 is not displayed even if the information in the name input field 403 and the DB 202 match. The reason is that when a health care worker calls a subject into a laboratory, it is common not to call by the subject's surname or the subject's surname, but only by the subject's name. In addition, since there are many subjects with the same name, even if a health care professional is made aware of the existence of a subject with the same name, it is often done. This is because there is a possibility that the attention of medical staff against the subject's mistakes may be reduced.

(T-4) If there is no subject with the same name and a subject with the last name of the subject entered earlier is photographing on the same day, the surname input item 402 remains lit.
(T-5) If there is a subject with the same surname, the first name entry item 403 is also lit. With this lighting, the medical staff can recognize that there is a subject with the same name and the same name on the same day. By informing medical professionals of the existence of a subject with the same surname on the same day, the ID, date of birth, address, telephone number, etc. of the subject that is not normally confirmed when bringing the subject into the laboratory Encourage health care professionals to directly check personally identifiable information and prevent subject mix-ups.

(T-6) When a subject with the same surname appears, he / she is prompted to enter and confirm other items such as the subject ID input field 404 or the birth date input field 405.
(T-7) If all the items match, it is suspected that the same subject has been taken twice or a medical worker has registered for a mistake. Prevent misunderstandings.
(T-8) If the other input items do not match, both the last name input field 402 and the first name input field 403 continue to be lit.
(T-9) If the subject's first and last names registered in the subject registration screen 401 and the subject's first and last names stored in the DB 202 do not exist, what is displayed on the registration screen 401? No warning information.

  Here, as notification of warning information to the operator in (T-2) and (T-5), not only lighting of the input field, but also blinking of the input field or a pop-up window 701 shown in FIG. 3 is displayed. The same is true for the first embodiment.

As described above, as one embodiment of the subject confirmation system of the present invention, when there is a similar subject with the same surname or the same surname in the same day photographing in the examination by the MRI apparatus, to the medical staff at the time of subject information registration Explained the subject confirmation function that can easily convey the existence of such a similar subject and prompt the medical staff to confirm the subject, but the present invention is not only for subjects photographed on the same day, It is also possible to discriminate against subjects who have been performed in the past.
In this case, the warning display to the medical staff on the subject registration screen 401 is performed by a method different from the warning display when there is a similar subject on the same day. For example, when the same family name or the same family name has the same family name on the same day, the health care worker can recognize the color by lighting the last name input field 402 in red, yellow in the past several weeks, and blue in the past. By allowing the medical staff to recognize that similar subjects exist in the past subjects, it is possible to reduce gaps in the imaging data.

  In the present embodiment, the case where the present invention is applied to the MRI apparatus has been described. However, the present invention is not limited to the MRI apparatus, and other medical image diagnostic apparatuses such as an X-ray diagnostic apparatus, an X-ray CT apparatus, and an ultrasonic diagnostic apparatus. It can also be applied as a subject confirmation means for preventing subject misplacement. Furthermore, a lock function of the inspection apparatus based on the confirmation results of the subject and the medical staff described in the first embodiment may be introduced.

  Further, in the above description, the MRI apparatus, which is a medical image diagnostic apparatus, is provided with the configuration of the present invention, and the subject confirmation is performed in the examination room. However, the second embodiment of the present invention is like this. It is not necessarily limited to any form. For example, if the configuration of the present invention is incorporated in another medical device installed in a clinic, the subject can be confirmed in the clinic. Further, the present invention can be provided as a program, and the subject can be confirmed by executing the program on a commercially available personal computer placed in a clinic or examination room.
