[0018] In the following embodiments, the present invention will be described in detail with reference to the drawings. Note that each drawing is merely a schematic illustration to allow a sufficient understanding of the present invention. Therefore, the present invention is not limited to the illustrated examples. In addition, in each drawing, common or similar components are given the same reference numerals, and redundant explanations thereof will be omitted.

[0019] The medical testing device 100 of an embodiment of the present invention comprises a communication unit 50 that is communicatively connected to a server (worklist server 200) via a network, a test information acquisition unit 3 that acquires test information (including patient information and test ID) for ordering a test from the server, a display control unit 8 that displays the acquired test information 11 on a display unit (display operation unit 40), a test information editing unit 4 that edits the acquired test information 11, and a volatile memory unit 20 that stores (temporarily stores) the edited test information 12 edited by the test information editing unit.

[0020] (First embodiment) FIG. 1 is a configuration diagram of a device operation system according to a first embodiment of the present invention. In the image inspection system S, a medical inspection device 100, a worklist server 200 as a server, and an electronic medical record system 250 as a server are communicably connected via a network. The medical inspection device 100 is an ultrasound diagnostic device equipped with an ultrasound probe 1.

[0021] The worklist server 200 stores examination information including patient information in a non-volatile storage unit (not shown) and transmits the stored examination information to the medical examination device 100. Here, the patient information is personal information such as the subject ID, name, sex, age, date of birth, height, weight, etc. The examination information includes the examination name, examination ID, etc. in addition to the patient information. In this embodiment, an examination (ultrasound diagnosis) is ordered by transmitting the examination information (especially the examination ID).

[0022] The electronic medical record system 250 is a medical information system that unifies paper medical records and various test results as electronic data. The electronic medical record system 250 may order tests (e.g., diagnostic imaging) from the medical testing device 100 in place of the worklist server 200.

[0023] The medical examination device 100 comprises an ultrasound probe 1, a control unit 10, a volatile memory unit 20 as a memory unit, a non-volatile memory unit 30 as a memory unit, a display operation unit 40 as a display unit, and a communication unit 50. The ultrasound probe 1 is a sensor in which a plurality of ultrasound transducers that generate ultrasound waves and a plurality of ultrasound receivers are arranged in a matrix.

[0024] The volatile storage unit 20 is a RAM (Random Access Memory) that has a storage area reserved for storing the examination information 11 and the edited examination information 12. The non-volatile storage unit 30 is a HDD (Hard Disk Drive) or SSD (Solid State Disk), etc. that has a storage area reserved for storing the edited examination information 22. The display operation unit 40 is a liquid crystal panel (display unit) that can be operated by touch. The communication unit 50 is communicably connected to either or both of the worklist server 200 and the electronic medical record system 250 via a LAN (Local Area Network), etc.

[0025] The control unit 10 is a CPU (Central Processing Unit), and by executing a program, it realizes the functions of an image processing unit 2, an examination information acquisition unit 3, an examination information editing unit 4, a search unit 5, an editing presence / absence determination unit 6, a selection unit 7, and a display control unit 8. The image processing unit 2 performs image processing on the ultrasound image signal output by the ultrasound probe 1, and causes the display operation unit 40 to sequentially display examination images (ultrasound diagnostic images). The examination information acquisition unit 3 acquires examination information including patient information from either or both of the worklist server 200 and the electronic medical record system 250 via the communication unit 50. At this time, an examination (ultrasound diagnosis) is ordered. The examination information acquisition unit 3 also stores the acquired examination information in the volatile storage unit 20 as examination information 11.

[0026] The examination information editing unit 4 displays and edits the examination information acquired by the examination information acquisition unit 3 and the edited examination information 22 stored in the non-volatile storage unit 30 on the display operation unit 40. In this embodiment, the examination information editing unit 4 particularly edits the patient information included in the examination information. In addition, the examination information editing unit 4 stores the edited examination information in the volatile storage unit 20 as edited examination information 12.

[0027] The search unit 5 searches for any of the examination information (including patient information) in the examination information 11 or the edited examination information 12 stored in the volatile storage unit 20. In particular, in this embodiment, the search unit 5 also functions as a same patient search unit that searches for whether or not the patient is the same patient.

[0028] The editing presence / absence determination unit 6 determines whether the search results searched by the search unit 5 include edited edited examination information 12. In other words, the editing presence / absence determination unit 6 determines whether the examination information (patient information) has been edited. The selection unit 7 selects one search result from the multiple search results searched by the search unit 5. The selection unit 7 displays the multiple search results on the display operation unit 40 and displays a screen that allows the operator to select one selection result. The display control unit 8 displays a screen (e.g., patient registration screen 300 (Figure 2)) generated by the image processing unit 2, examination information editing unit 4, search unit 5, editing presence / absence determination unit 6, and selection unit 7 on the display operation unit 40. In addition, the display control unit 8 outputs operation information performed on the display operation unit 40 to each unit.

[0029] FIG. 2 is a diagram showing an example of the patient registration screen. The upper left side of the patient registration screen 300 is provided with an examination "ID" column 301, a "Name" column 312, a "Date of Birth" column 313, and an "Age" column 314. The "Name" column 312 is comprised of a name in kana column 302, a name in kanji column 303, and a name in alphabet column 304. The upper center part of the patient registration screen 300 is provided with a "Gender" column 315, an "Examiner" column 316, a "Height" column 317, and a "Weight" column 318. The upper right side of the patient registration screen 300 is provided with a current date and time display column 320, a "Clear" button 321, an "Edit" button 322, a "Start Examination" button 323, and a "Close" button 324.

[0030] The lower section of the patient registration screen 300 contains an "Examination Date" column 345, an "Update" button 346, and a "Scheduled Examination List" table. This scheduled examination list contains, in rows, an examination "ID" column 331, a "Name" column 332, a "Date of Birth" column 333, an "Age" column 334, a "Gender" column 335, and an "Examination Start Date" column 336. The "Scheduled Examination List" is a list in which the "Examination Date" column 345 is set to "Today," and scheduled examinations for patients with the same examination start date, "2022 / 05 / 30," are listed across multiple rows. The "Name" column 332 is also the same.

[0031] The "patient information" in FIG. 2 is the examination information 11 obtained from either or both of the worklist server 200 and the electronic medical record system 250 and stored in the volatile memory unit 20 (FIG. 1). In this embodiment, the name in the worklist is assumed to be "One Secondary Caputu" in alphabets or Roman letters only, and the gender is assumed to be "Other." Therefore, the name in kana column 302 and name in kanji column 303 in the "patient information" in the upper row are left blank. Furthermore, the "gender" column 315 in the upper row and the "gender" column 335 in the "scheduled examination list" in the lower row match, being "Other."

[0032] FIG. 3 is a flowchart for editing patient information. The worklist server 200 transmits examination information including patient information to the medical examination device 100 (step S1). The communication unit 50 of the medical examination device 100 receives the examination information including patient information (step S2). At this time, the communication unit 50 of the medical examination device 100 receives an examination ID, and an examination (ultrasound diagnosis) is ordered. The examination information acquisition unit 3 (FIG. 1) stores the received examination information in the volatile memory unit 20 as examination information 11. After processing in step S2, the display control unit 8 of the medical examination device 100 displays the examination information (including patient information) received in step S2 on the display operation unit 40 (step S3). At this time, the display control unit 8 of the medical examination device 100 may display the edited examination information 22 stored in the non-volatile memory unit 30 on the display operation unit 40. For example, the display control unit 8 of the medical examination device 100 displays the patient registration screen 300 (FIG. 2) on the display operation unit 40.

[0033] After processing step S3, the operator checks the patient registration screen 300 (FIG. 2) and presses the "Edit" button 322 (step S4). The control unit 10 of the medical testing device 100 determines whether the "Edit" button 322 has been pressed (step S5). If the "Edit" button 322 has not been pressed ("Not Pressed" in step S5), the control unit 10 of the medical testing device 100 repeats the determination of step S5. If the "Edit" button 322 has been pressed ("Pressed" in step S5), the display control unit 8 of the medical testing device 100 displays a confirmation message on the display operation unit 40 (step S6).

[0034] FIG. 4 is a diagram showing an example of a screen displayed when starting to edit patient information. The screen in Fig. 4 is a pop-up display of a message dialog box 350 on the patient registration screen 300 (Fig. 2). The message dialog box 350 includes the character string "Message" and the character string "Do you want to change the patient information in the scheduled examination list?", an "OK" button 351, and a "Cancel" button 352. Note that Fig. 4 shows the state in which the "Edit" button 322 has been pressed in step S4 (Fig. 3).

[0035] Returning to the explanation of the flowchart in FIG. 3, the operator presses the "OK" button 351 in the message dialog box 350 (step S7). After processing step S6, the control unit 10 of the medical testing device 100 determines whether the "OK" button 351 has been pressed (step S8). If the "OK" button 351 has not been pressed ("not pressed" in step S8), the control unit 10 of the medical testing device 100 repeats the determination of step S8. On the other hand, if the "OK" button 351 has been pressed ("pressed" in step S8), the display control unit 8 of the medical testing device 100 causes the display operation unit 40 to display the editing screen 400 (FIG. 5) (step S10).

[0036] FIG. 5 is a diagram showing an example of an editing screen for editing patient information. The editing screen 400 has the same configuration as the patient registration screen 300 (FIG. 2). However, the editing screen 400 has a "Save" button 325 (FIG. 5) and a "Cancel" button 326 (FIG. 5) instead of the "Start Examination" button 323 (FIG. 2) and the "Close" button 324 (FIG. 2). The "Save" button 325 is a button for instructing whether or not to store the edited examination information 12 stored in the volatile storage unit 20 in the non-volatile storage unit 30 as edited examination information 22. Therefore, the editing screen (FIG. 5) functions as a confirmation screen for confirming whether or not to record the edited examination information 12 in the non-volatile storage unit 30. That is, the display control unit 8 causes the display operation unit 40 to display a confirmation screen for confirming whether or not to record the edited examination information in the non-volatile storage unit 30.

[0037] Returning to the explanation of the flowchart in FIG. 3, the worker uses the editing screen 400 (FIG. 5) to edit the patient information (step S9). For example, the worker fills in the blank name in kana column 302 and name in kanji column 303 during the medical interview. The worker also changes the "gender" column 315 from "other" (FIG. 2) to "female." As a result, the examination information 11 (FIG. 1) is edited, and edited examination information 12 (FIG. 1) is stored in the volatile memory unit 20.

[0038] After editing the patient information (step S9), the operator presses the "Save" button 325 (step S11). After processing step S10, the control unit 10 of the medical testing device 100 determines whether the "Save" button 325 has been pressed (step S12). If the "Save" button 325 has not been pressed ("Not Pressed" in step S12), the medical testing device 100 repeats the determination in step S12. On the other hand, if the "Save" button 325 has been pressed ("Pressed" in step S12), the control unit 10 of the medical testing device 100 saves (records) the edited patient information (edited examination information 12) stored in the volatile storage unit 20 (FIG. 1) as edited patient information (edited examination information 22) in the non-volatile storage unit 30 (FIG. 1) (step S13), and the processing of FIG. 3 ends.

[0039] The edited examination information 22 may be configured to be transmitted (feedback) to either or both of the worklist server 200 and the electronic medical record system 250. Here, whether or not the worklist is changed depends on the specifications of the worklist server 200.

[0040] FIG. 6 is a flowchart showing the process of searching for edited patient information. This flow is started by pressing a "Search" button (not shown) or the like. In this embodiment, a search for a "Scheduled Examination List" will be described as an example. That is, the flow in FIG. 6 is started by the operator setting "Examination Date" field 345 (FIG. 2) to "Today" and pressing the "Update" button 346.

[0041] The search unit 5 of the medical testing device 100 searches for the edited test information 12 stored in the volatile memory unit 20 (step S21) and displays the search results on the display operation unit 40 (step S22). For example, in the "Scheduled Test List" of FIG. 2, search results in which the "Test Start Date" column 336 is today, "2022 / 05 / 30," are displayed across multiple rows. The operator selects edited patient information (step S23). For example, the operator selects the selected row 340 (FIG. 2). The control unit 10 of the medical testing device 100 determines whether one search result has been selected from the multiple search results (step S24). If no selection has been made ("NO" in step S24), the control unit 10 of the medical testing device 100 repeats the determination of step S24. On the other hand, if a selection has been made (YES in step S24), the display control unit 8 of the medical testing device 100 causes the display operation unit 40 to display a screen (not shown) showing the selection result (step S25), and the processing in FIG. 6 ends.

[0042] FIG. 7 is a flowchart for searching for patient information of the same patient according to the first embodiment of the present invention. This flow is started when a patient name is set and the "Same Patient" button (not shown) is pressed. The search unit 5 of the medical testing device 100 searches for patient information (examination information) of the same patient using the patient information (examination information 11) stored in the volatile storage unit 20 (step S31). After processing in step S31, the control unit 10 of the medical testing device 100 determines whether or not editing has been performed on the same patient using the edited patient information (edited examination information 12) (step S32). If editing has been performed ("Yes" in step S32), the display control unit 8 of the medical testing device 100 causes the edited patient information (edited examination information 12) to be displayed on the display operation unit 40 (step S33). On the other hand, if editing has not been performed ("No" in step S32), the display control unit 8 of the medical testing device 100 causes the patient information (examination information 11) to be displayed on the display operation unit 40 (step S34), and the processing of FIG. 7 ends.

[0043] As described above, the display control unit 8 of the medical testing device 100 of this embodiment displays test information (including patient information and test ID) acquired from either or both of the worklist server 200 and the electronic medical record system 250 on the display operation unit 40. The medical testing device 100 receives test information and orders a test. When the "Edit" button 322 (FIG. 2) is pressed, the medical testing device 100 pops up a message dialog box 350 (FIG. 4). When the "OK" button 351 (FIG. 4) in the message dialog box 350 is pressed, the displayed test information 11 can be edited.

[0044] The edited edited examination information 12 is recorded as edited examination information 22 in the non-volatile memory unit 30 by pressing the "Save" button 325. If the patient name on the worklist is written only in alphabets or Roman letters, it can be added to the kana name field 302 or the kanji name field 303 (FIGS. 2 and 5) by editing and recording in the non-volatile memory unit 30. This reduces the risk of misidentifying patients in subsequent examinations performed using the medical examination device 100.

[0045] The edited examination information 22 recorded in the nonvolatile storage unit 30 is transmitted (feedback) by the communication unit 50 to either or both of the worklist server 200 and the electronic medical record system 250. Here, whether or not the worklist is updated depends on the specifications of the worklist server 200.

[0046] (Second embodiment) 7 of the first embodiment, the display control unit 8 of the medical testing device 100 only displays either the patient information (examination information 11) or the edited patient information (edited examination information 12) on the display operation unit 40, depending on whether editing has been performed. The display control unit 8 may be configured to display the patient information (examination information 11) and the edited patient information (edited examination information 12) on the display operation unit 40, and allow the user to select either one.

[0047] FIG. 8 is a flowchart showing a process of searching for patient information of the same patient executed by the testing device according to the second embodiment of the present invention. The search unit 5 of the medical testing device 100 searches for patient information of the same patient using the patient information (examination information 11) stored in the volatile storage unit 20 (step S41). After processing in step S41, the edit presence / absence determination unit 6 of the medical testing device 100 determines whether editing has been performed on the same patient using the edited patient information (edited examination information 12) (step S42). If editing has not been performed on the same patient ("No" in step S42), the display control unit 8 of the medical testing device 100 causes the display operation unit 40 to display the examination information 11 (step S43). On the other hand, if editing has been performed on the same patient ("Yes" in step S42), the display control unit 8 of the medical testing device 100 causes the display operation unit 40 to display both the examination information 11 and the edited examination information 12 (step S44).

[0048] After processing step S44, the selection unit 7 of the medical examination device 100 accepts a selection input for selecting whether to adopt the examination information 11 or the edited examination information 12 (step S45). After processing step S45, the selection unit 7 of the medical examination device 100 determines whether the examination information 11 or the edited examination information 12 was selected in the selection input of step S45 (step S46). If the examination information 11 is selected ("Examination Information" in step S46), the selection unit 7 of the medical examination device 100 adopts the examination information 11 (step S47) and ends the process. On the other hand, if the edited examination information 12 is selected ("Edited Examination Information" in step S46), the selection unit 7 of the medical examination device 100 adopts the edited examination information 12 (step S48). After processing step S48, the communication unit 50 of the medical examination device 100 transmits the edited examination information 12 to the worklist server 200 (step S49) and ends the process. The worklist server 200 receives the edited inspection information 12 (step S50) and provides feedback. At this time, the worklist server 200 may or may not update the worklist.
