Alternatively, if the device is associated with the patient and the examination is performed only with the device, all the past data is stored in the device, so the above analysis can be performed, but the device is in use. Even if other devices were available, the patient had to wait until the device was available. In addition, the utilization efficiency of the apparatus has been lowered.

  For this purpose, a system that allocates media (recording media) to each patient, records medical document data and medical image data such as basic personal information and examination data, and uses the data recorded on the media. (For example, refer to Patent Document 1).

  In this case, all of the patient's data is recorded on the media, but every time it tries to use the data during the examination, it takes a lot of time to read the data from the media, resulting in wasted examination time. End up.

  In addition, in order to allocate media for each patient, media for at least the number of patients must be prepared and managed.

  In addition, personal data may be distributed and recorded on a plurality of media. Since the media carried by the patient during examinations and the like increases, the media may be lost or damaged due to dropping during carrying.

(Additional storage procedure from past inspection data media to storage means)
FIG. 4 is a flowchart showing a procedure for additionally storing past inspection data from the medium to the storage means. With reference to FIG. 4, a procedure for additionally storing past inspection data from the medium to the storage means will be described.

  First, the patient A receives the media 16a and takes it to the ultrasonic diagnostic apparatus. The doctor who conducts the inspection first wears the medium 16a (step S101, hereinafter abbreviated as S101, and the same applies to others). When the medium 16a is attached, the control unit 10 causes the display unit 12 to display an instruction display for patient ID input (S102). When the patient ID is inputted (S103, Y), the examination data recorded in the media 16a of the inputted patient ID is compared with the examination data stored in the storage means 14, and stored in the storage means 14. Unexamined past inspection data is extracted from the medium 16a and additionally stored in the storage means 14 (S104). FIG. 5 (a) shows the state of the storage means 14 before the additional storage, in which the control program, application program, and patient information of each patient are stored, and FIG. This shows how the inspection data is additionally stored. The comparison of the inspection data can be performed using information indicating the inspection data described in the header portion of the inspection data, for example. Specifically, information indicating the examination data of the patient ID input from the medium 16a may be extracted, and the storage unit 14 may be searched to check the presence / absence of the extracted information.

  In this way, all of the past examination data of the patient undergoing the examination is stored in the ultrasonic diagnostic apparatus in which the patient is to undergo the examination. For example, the examination data and the past examination data from the examination to be performed from now on are stored. It is possible to compare with and create and display trend graphs. Further, when only past storage of past inspection data is performed, it may be performed as described above. Further, since the additional storage is performed only for the past inspection data that is insufficient, it can be stored in a minimum time.

  In the above description, the examination data of the patient to be examined is additionally stored. However, all the examination data recorded on the medium 16a is targeted, and the medium 16a not stored in the storage unit 14 is targeted. It is also possible to extract past test data recorded only in the memory and additionally store it in the storage means 14.

(Recording procedure of this inspection data to media)
FIG. 6 is a flowchart showing a procedure for recording the current inspection data on the medium. The procedure for recording the current inspection data on the medium will be described with reference to FIG.

  Following the additional storage of the past examination data from the medium to the storage means, the examination of the patient A is performed by the examination unit 11 (S201). The control unit 10 displays the generated image information on the display unit 12 (S202), the doctor operates the operation panel 13 so as to create examination data, receives an input of the operation (S203), and the control unit 10 creates inspection data (S204). Alternatively, the doctor operates the operation panel 13 to input a diagnosis result, receives the input of the operation in S203, and creates examination data in S204. The created inspection data is added and stored in the storage means 14 (S205). Further, when the inspection is continued, the inspection unit 11 performs the inspection, creates inspection data, and stores it in the storage unit 14 as in S201 to S204 described above. As shown in FIG. 5C, the current examination data of the patient A is additionally stored. Therefore, all the examination data of the patient A is stored in the apparatus that the patient A last examined. Alternatively, it may be temporarily stored in the system memory of the control unit 10 and stored in the storage unit 14 when the inspection is completed.

  When the inspection is completed (S206, Y), the control unit 10 checks the free capacity of the loaded medium 16a. If it is determined that there is a capacity to record the current examination data and can be recorded (S207, yes), the driver apparatus is configured to record the current examination data on the medium 16a in a general format in association with the patient ID inputted first. 15 is controlled (S214). FIG. 7 shows a state in which the current examination data of the patient A is additionally recorded on the medium 16a. All the examination data of the patient A is stored in the medium 16a. In this case, the patient A also uses the medium 16a in the next examination.

  If it is determined that recording is not possible due to insufficient capacity (S207, impossible), first, the control unit 10 causes the display unit 12 to display a replacement support display of the medium 16a (S208). Then, when the medium is replaced with another medium 16b or medium 16c, the control unit 10 checks the free space of the replaced medium 16b or medium 16c. Here, in the present embodiment, the capacity check is performed because patient information about a plurality of patients is recorded on one medium 16, so that the capacity information is replaced with a medium 16 b in which patient information of the patient D has already been recorded. Because there is. If it is determined that recording is not possible due to insufficient capacity (S210, impossible), the replacement support display is displayed again (S208).

  When it is determined that there is a capacity and recording is possible (S210, Yes), the control unit 10 determines whether or not the medium is newer, and if it is a new medium (S211, Y), in this example, when the medium 16c is loaded The media number as the media management information and the application program are recorded, and the patient information including the current examination data and the past examination data of the patient A stored in the storage means in association with the patient ID of the patient A is general-purpose. The driver device 15 is controlled to record in the format (S212). FIG. 8 shows a state recorded on the medium 16c. All the examination data of the patient A is stored in the medium 16c. In this case, the patient A uses the medium 16c at the next examination.

  If it is not a new medium (S211, N), in this example, when the medium 16b is mounted, the patient with the patient ID stored in the examination data created this time in association with the patient ID input first and the storage means The driver device 15 is controlled so as to record information in a general-purpose format (S213). FIG. 9 shows a state recorded on the medium 16b. All the examination data of the patient A is stored in the medium 16b. In this case, the patient A uses the medium 16b at the next examination.

  As described above, personal patient information can be recorded on the medium 16 without being dispersed. Then, when an inspection is performed by a device that does not store all past inspection data, the past inspection data can be additionally recorded from the medium 16, and all the inspection data can be stored in the device. In addition, FIG. 3A shows an example in which the media 16 can be shared by a plurality of patients. However, according to a DVD or the like, patient information of several tens of patients can be recorded. The total number of 16 can be reduced. Further, since additional recording is performed on the medium and rewriting is not performed, the risk of destroying data is small.

  The recording format on the media is not particularly limited to the general-purpose format, but by recording in the general-purpose format, the inspection data can be decoded by other devices, and the display provided in the device This is because display can be performed using the program.

  In addition, since the application program for display as described above is recorded on the medium 16, for example, when the application program is not stored in the ultrasonic diagnostic apparatus that performs the inspection, the application program is recorded on the medium 16. Display based on an application program can be performed by loading and installing a program for displaying inspection data and a program for creating and displaying a comparison display or a trend graph using the inspection data. In addition, the display of examination data based on this application program can be executed not only on the ultrasonic diagnostic apparatus but also on a workstation by loading and installing the program. Specifically, application programs for displaying these were obtained, for example, those that display important frames in a moving picture with frame numbers, those that display information or image data related to the diagnosis results, and the like. There are a loop reproduction between R waves of an electrocardiogram waveform, a synchronous display of a plurality of moving images with an electrocardiogram waveform, a list display of examination data, and the like.

  Also, by loading and installing a data conversion program for recording in a general-purpose format on an ultrasound diagnostic apparatus that does not have that program, it can be recorded in a general-purpose format, so that other devices can decode the inspection data, The display can be performed using a display program provided.
