Description

  The present invention relates to an ultrasonic diagnostic apparatus that protects patient information by automatically logging off when a patient is no longer recognized.

  In medical devices, protecting personal information of patients has become an important issue in recent years. For example, it should not be possible for another patient or an unsupported doctor to see a monitor screen on which an image of a tumor is displayed.

For this reason, in general, when using a medical device such as an ultrasonic diagnostic apparatus, the patient information is protected by logging on to the device at the time of examination and performing logoff processing when the examination for the patient is completed. (See Patent Documents 1 and 2).

  However, in the conventional technique, logoff is performed by a doctor operating the console or when a certain time has passed. Therefore, when the doctor forgets to execute the logoff operation, there is a problem that a time when personal information is not protected occurs.

  In order to solve the above problems, the present invention provides a patient detection unit for detecting the presence of a patient and a current display in an ultrasonic diagnostic apparatus having a screen for displaying patient information. The patient information holding unit that holds the ID information of the patient who is doing, the patient ID information from the patient detection unit and the patient ID information from the patient information holding unit are collated, so that the currently displayed patient information A patient presence determination unit that determines whether or not a corresponding patient exists, and a test that performs logoff when there is no patient corresponding to the currently displayed patient information based on a signal from the patient presence determination unit And an end control unit.

  With this configuration, by providing a function of logging off when there is no patient, the personal information of the patient can be protected even when the doctor has not logged off after the examination.

  According to the present invention, in an ultrasonic diagnostic apparatus having a screen for displaying patient information, the patient detection unit for detecting the presence of the patient and the currently displayed patient ID information are provided. Whether there is a patient corresponding to the currently displayed patient information by collating the patient information holding unit, the patient ID information from the patient detection unit and the patient ID information from the patient information holding unit A patient presence determination unit that determines whether or not and an examination end control unit that performs logoff when there is no patient corresponding to the currently displayed patient information based on a signal from the patient presence determination unit Yes.

  With this configuration, an ultrasonic diagnostic apparatus having an effect of protecting the patient's personal information even if the doctor has not logged off after the examination by providing a function to log off when the patient no longer exists It is to provide.

  Hereinafter, an ultrasonic diagnostic apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  An ultrasonic diagnostic apparatus according to a first embodiment of the present invention is shown in FIG.

  In FIG. 1, an ultrasonic diagnostic apparatus 6 includes a patient detection unit 7 that detects the presence of a patient, a patient information holding unit 8 that holds the ID information of the currently displayed patient, and patient ID information from the patient detection unit. And patient ID information from the patient information holding unit, a patient presence determination unit 9 that determines whether there is a patient corresponding to the currently displayed patient information, and a signal from the patient presence determination unit Thus, when there is no patient corresponding to the currently displayed patient information, the examination end control unit 10 executes logoff, the console 11 used by the doctor to operate the ultrasonic diagnostic apparatus, and the patient information. The display unit 12 displays a screen.

  The operation of the ultrasonic diagnostic apparatus configured as described above will be described with reference to FIG.

  First, at the time of examination, the doctor logs in through the console 11 as usual, and then examines the patient. At this time, the patient detection unit 7 transmits the detected patient ID information to the patient presence determination unit 9. Since the result of comparing the patient ID information from the patient detection unit and the currently displayed patient ID information from the patient information holding unit 8 matches, the patient determination transmission unit 9 does not perform any further operation. When the examination is completed and there are no more patients, the patient detection unit 7 detects that there are no more patients, and sends patient ID information in a blank (“no patient present” state) defined in advance to the patient presence determination unit 9. The patient presence determination unit 9 that has received the patient ID information from the patient detection unit 7 compares it with the currently displayed patient ID information from the patient information holding unit 8 and determines that there is no patient because the results do not match. At the same time, a predetermined logoff signal is transmitted to the inspection end control unit 10 at a transmission timing that is arbitrarily set separately. Upon receiving the signal from the patient presence determination unit 9, the examination end control unit 10 executes a logoff operation, and the screen of the ultrasonic diagnostic apparatus and patient information are all deleted from the display unit 12 during this process. This transmission timing is linked to the size of the detection area of the patient detection unit 7, but is set to be equal to or less than the time until the next patient enters the examination room by making a call to call the next patient at the longest. Is preferred.

  In addition to the method using biometrics technology such as fingerprint, iris, face authentication, vein authentication, etc., the patient detection unit 7 possesses an infrared sensor, an optical sensor using a thermograph pattern or a laser, and a recognition tag. Recognize the radio frequency identification (RFID) and other electrical methods, weight measurement methods using weight sensors on the floor and chair, or odor detection methods that distinguish individual odors based on illness and medicine, voice A method such as an acoustic method for detecting and discriminating sound can be used.

  When an RFID tag is used as the patient detection unit, the ID information of the tag attached by the patient acquired by the tag reader may be input to the patient presence determination unit in combination with a commercially available tag reader.

  Further, when an ID card is used as the patient detection unit, it is only necessary to input the ID information of the patient's card inserted into the card reader into the patient presence determination unit in combination with a commercially available card reader.

  According to the ultrasonic diagnostic apparatus of the first embodiment of the present invention as described above, even if the doctor does not log off after the end of the examination, it automatically logs off by detecting that the patient is gone. This has the effect of protecting patient information.

  Next, FIG. 2 shows an ultrasonic diagnostic apparatus according to the second embodiment of the present invention.

  As shown in FIG. 2, by providing a delay / screen switching unit 13 that can be reset by a signal from the console in front of the test end control unit 10, when the test is completed and there is no patient, the test end control unit is immediately Instead of sending a log-off signal to 10, a screen for inquiring whether or not to log off is once displayed on the display unit 12 (the patient information screen is hidden from the display unit 12, or the screen display is modified and cannot be discriminated. When the log-off execution is selected by an input from the console 11, the log-off is executed, and when the log-off execution is selected by an input from the console 11. Can redisplay the original patient information display screen before the inquiry screen is displayed.

  By doing in this way, even if a patient leaves, when a patient information needs to be reviewed as a doctor, it can respond intentionally.

  Note that the delay / screen switching unit 13 may be included in the inspection end control unit 10 in terms of a circuit.

  In addition, the patient detection unit 7 detects not only the patient but also the doctor, and the doctor identification information and the patient information are registered in a linked form, so that not only the patient but also the doctor cannot be detected ( When the doctor moves away from the device by more than a certain distance), in order to prevent personal information from leaking not only to other patients but also to other doctors, a logoff signal is sent to the test end control unit 10 and the logoff operation is executed. It is preferable to do.

  Also, the patient detection unit 7 transmits a plurality of different patient ID information to the patient presence determination unit 9, and the patient presence determination unit 9 currently displays the ID information of the patient (hereinafter referred to as patient A) from the patient information holding unit 8. When there is patient information that does not match the logoff signal, a logoff signal can be sent to the test end control unit 10 to execute a logoff operation.

  With such a configuration, when another patient (hereinafter referred to as patient B) enters the detection area of the patient detection unit 7 by mistake, the patient B is shown information about patient A from the standpoint of prioritizing protection of personal information. Can be eliminated and patient information can be protected.

  Next, FIG. 3 shows an ultrasonic diagnostic apparatus according to the third embodiment of the present invention.

  As shown in FIG. 3, when there is a possibility that a companion of the patient A exists with the patient A by providing the companion detection unit 14 in the patient detection unit 7, the companion is previously a companion. Even if the patient detection unit 7 detects a plurality of human bodies by registering a certain thing, the companion data detected by the companion detection unit 14 is deleted from the detection information, or the transmission data to the subsequent process By attaching the identifier to the patient presence determination unit 9, only the patient ID information of only the patient A is discriminated, so that the patient A shares personal information with the accompanying person, Can protect personal information.

  As described above, the ultrasonic diagnostic apparatus according to the present invention automatically logs off the patient information by detecting that the patient is gone, even if the doctor does not log off after completion of the examination. It has the effect of being able to be protected, and is useful as a method for eliminating errors in protecting patient information when many doctors make a diagnosis.
