[0024] 3 is a block diagram showing a schematic functional configuration of the medical device 10. The medical device 10 includes a control unit 60. The control unit 60 includes a processor 60a such as a central processing unit (CPU), a memory 60b such as a random access memory (RAM) or a read only memory (ROM), and a storage device 60c such as a hard disk drive (HDD) or a solid state drive (SSD).

[0025] The control unit 60 controls the overall operation of the medical device 10 in accordance with a program stored in the memory 60b, for example, by the processor 60a executing the program. The processor 60a may execute a program stored in any storage device other than the memory 60b, or may execute a program acquired from any recording medium via a reading device, or may execute a program acquired via a network. The memory 60b storing the program may be a volatile memory such as a dynamic random access memory (DRAM), or a nonvolatile memory such as an electrically erasable programmable read-only memory (EEPROM), flash memory, magnetoresistive memory, variable resistance memory, or ferroelectric memory. Nonvolatile memory, magnetic recording media such as magnetic tape and magnetic disks, and optical recording media such as optical disks are examples of non-transitory, tangible, computer-readable storage media.

[0026] The control unit 60 is connected to various devices (e.g., sensors) provided in the main body 12, for example, via a system bus 62. The control unit 60 acquires a signal from a holding sensor 22a provided in the coupler holder 22. The holding sensor 22a detects whether the dialysis fluid coupler 26 is set in the coupler holder 22. The control unit 60 acquires a signal from an empty fluid sensor 28. The empty fluid sensor 28 detects whether there is fluid inside the fluid replacement line 56. The control unit 60 acquires a signal from a cover opening / closing sensor 30a provided in the blood pump 30. The cover opening / closing sensor 30a detects whether a cover provided in the blood pump 30 is opened or closed. The control unit 60 acquires a signal from a push sensor 34a provided in the fluid replacement line clamp 34. The push sensor 34a detects the depression of a push button operated to attach the fluid replacement line 56 to the fluid replacement line clamp 34.

[0027] The controller 60 acquires signals from the arterial sensor 36a and the venous sensor 36b provided in the main line clamp 36. The arterial sensor 36a detects whether the arterial blood circuit 52 is attached to the main line clamp 36. The arterial sensor 36a may include a sensor that detects the presence or absence of air bubbles or blood flowing through the arterial blood circuit 52. The venous sensor 36b detects whether the venous blood circuit 54 is attached to the main line clamp 36. The venous sensor 36b may include a sensor that detects the presence or absence of air bubbles or blood flowing through the venous blood circuit 54. The controller 60 acquires a signal from a cover sensor 38a provided in the blood volume monitor 38. The cover sensor 38a detects whether a cover provided in the blood volume monitor 38 is open or closed. The controller 60 acquires a signal from a lever sensor 46a provided in the drain port 46. The lever sensor 46a detects whether a lever provided in the drain port 46 is open or closed.

[0028] The control unit 60 is connected to the display unit 14 via, for example, a system bus 62. The control unit 60 controls the display content of the display unit 14. The control unit 60 acquires signals from a touch sensor 14a provided on the display unit 14. The touch sensor 14a detects user operations on the display unit 14. The control unit 60 causes images stored in the memory 60b or the storage device 60c to be displayed on the display unit 14. The control unit 60 changes, switches, or updates the images displayed on the display unit 14 based on signals from various sensors, for example, to sequentially display an installation procedure for installing consumables in the main body 12.

[0029] 4 is a diagram showing an example of an explanation screen 70 displayed on the display unit 14. The explanation screen 70 includes an overall image 72, a detailed image 74, an incidental image 76, and an explanation 78.

[0030] The overall image 72 is an image depicting the state of the front of the main body 12 and depicting multiple attachment portions to which consumables are attached. The overall image 72 shows, for example, the front of the main body 12 in a state where all consumables have been attached and the installation procedure is complete. For example, the overall image 72 shown in FIG. 4 includes the blood purifier 50, arterial blood circuit 52, venous blood circuit 54, and fluid replacement line 56 that are attached to the main body 12. The overall image 72 may show the front of the main body 12 in a state where no consumables have been attached, or may show the front of the main body 12 in a state where some consumables have only been partially attached. The overall image 72 does not change display depending on the progress of the installation procedure, and may be common to multiple steps that make up the installation procedure.

[0031] The detailed image 74 depicts the status of at least one of the multiple steps constituting the installation procedure. The detailed image 74 switches display depending on the progress of the installation procedure and shows details of the step the user is currently working on. The detailed image 74 shows the main body 12 from a different perspective than the overall image 72, such as a left-side perspective view or a right-side perspective view of the main body 12. The detailed image 74 may also show an enlarged view of the area where the user is working, or may show the empty fluid sensor 28 or the replacement fluid bag 58, which are not shown in the overall image 72. The detailed image 74 may also show the area where the user is working in a different display mode from the other areas. For example, the area where the user is working may be displayed in color and the other areas may be grayed out. For example, the detailed image 74 shown in FIG. 4 depicts the step of attaching the pressure pod 52b of the arterial blood circuit 52 to the arterial pressure port 32. The arterial blood circuit 52 and the pressure pod 52b are displayed in red, and the other areas are grayed out. The detailed image 74 is displayed in a different area from the entire image 72 so as not to overlap with the entire image 72 .

[0032] The accessory image 76 is an image superimposed on a portion of the overall image 72 or the detailed image 74. The accessory image 76 is displayed to highlight a specific portion of the overall image 72 or the detailed image 74. The accessory image 76 is displayed in a portion related to at least one step shown in the detailed image 74, and is displayed at a position depicting attachment parts or consumables related to at least one step. The accessory image 76 may be displayed in only one portion, or simultaneously in each of multiple portions. The accessory images 76 shown in FIG. 4 are displayed at a position depicting the arterial pressure port 32 and a position depicting the main line clamp 36 in the overall image 72. These images correspond to the step of attaching the pressure pod 52b to the arterial pressure port 32 shown in the detailed image 74 and the step of attaching the arterial blood circuit 52 to the main line clamp 36 shown in the detailed image 74. The accessory images 76 are changed or updated according to the progress of the attachment procedure; for example, the displayed position of the accessory images 76 is changed according to the progress of the attachment procedure.

[0033] The auxiliary image 76 preferably has a display form that allows it to be easily distinguished from the consumables and attachment parts shown in the overall image 72 and the detailed image 74. The auxiliary image 76 preferably has a simple shape, such as a circle, ellipse, polygon, or star. The auxiliary image 76 preferably has a display color different from the display colors (e.g., red and blue) used in the overall image 72 and the detailed image 74, and can have a display color, for example, yellow or green. The auxiliary image 76 may be configured so that its display size or display color changes periodically. The auxiliary image 76 may be displayed in a flashing manner. The auxiliary image 76 may have a transparent (e.g., semi-transparent) display form to ensure visibility of the superimposed portion.

[0034] 5A to 5F are diagrams illustrating an example of the display process of the accessory images 76. The accessory images 76 are displayed in order over time, with the first image 76a, the second image 76b, the third image 76c, the fourth image 76d, the fifth image 76e, and the sixth image 76f, and then returning to the first image 76a after the sixth image 76f is displayed. The accessory images 76a to 76f are configured so that their display size increases over time while their display color becomes lighter (or their transparency increases) over time. The rate of change in the display size and color over time may be constant or may change over time. The display cycle of the accessory images 76a to 76f is, for example, approximately 1 to 2 seconds. Each display cycle of the accessory images 76a to 76f may include an interval period during which the accessory images 76 are not displayed. The interval period may be set after the sixth image 76f is displayed and before the display returns to the first image 76a.

[0035] Returning to Figure 4, the explanatory text 78 is a character string or sentence that explains at least one step shown in the detailed image 74. The explanatory text 78 is displayed in an area different from the overall image 72 and the detailed image 74, and is displayed so as not to overlap with the overall image 72 and the detailed image 74. The explanatory text 78 shown in Figure 4 states, "Attach the blood purifier and replacement fluid bag. Set the arterial blood circuit in the pressure pod and main line clamp (left groove).", which corresponds to the step shown in the detailed image 74.

[0036] The explanation screen 70 may further include a start button image 80. The start button image 80 is an operation button for starting priming, and becomes operable when the installation work of the consumables is completed. In the explanation screen 70 shown in FIG. 4, the start button cannot be operated because the installation work of the consumables has not been completed, and the start button image 80 is displayed in gray.

[0037] An explanation screen 70 is prepared for each process group including, for example, two or more related processes. In the explanation screen 70 for explaining the first process group, an auxiliary image 76 is superimposed on a portion of an overall image 72 related to two or more processes included in the first process group, and two or more detailed images 74 are displayed in a switching manner to explain the two or more processes included in the first process group. The two or more detailed images 74 can be displayed in a switching manner in a predetermined order. A screen number may be assigned to the explanation screen 70 for each process group.

[0038] 6(a) to 6(e) are diagrams showing an example of the display process of detailed images 74a to 74e, and show the display process of detailed images 74 displayed simultaneously with the overall image 72 on the explanation screen 70 for the first process group shown in Fig. 4. The detailed images 74 are displayed in order over time: first detailed image 74a, second detailed image 74b, third detailed image 74c, fourth detailed image 74d, and fifth detailed image 74e, and then return to the first detailed image 74a after the fifth detailed image 74e is displayed.

[0039] The first detailed image 74a in Fig. 6(a) shows the process of attaching the blood purifier 50 and the fluid replacement bag 58, with the blood purifier 50 and the fluid replacement bag 58 displayed in color and the other parts grayed out. The second detailed image 74b in Fig. 6(b) shows the process of opening the cover of the main line clamp 36, with the main line clamp 36 displayed in color with the cover open. The second detailed image 74b also displays in color the arterial pressure port 32, which should be the focus of attention in the next process in the third detailed image 74c.

[0040] A third detailed image 74c in Fig. 6(c) shows the process of attaching the pressure pod 52b to the arterial pressure port 32 and attaching the arterial blood circuit 52 to the main line clamp 36. The third detailed image 74c shows the attached arterial blood circuit 52 in color. A fourth detailed image 74d in Fig. 6(d) shows the process of closing the cover of the main line clamp 36, and shows the main line clamp 36 in color with the cover closed.

[0041] 6(e) shows the process of temporarily holding the remaining portion of the arterial blood circuit 52 extending below the main line clamp 36 by winding it around the tube hook 48. In the fifth detailed image 74e, the arterial blood circuit 52 wound around the tube hook 48 and the purifier-side end portion 52e are displayed in color.

[0042] Identification images 82a-82e are superimposed on the detailed images 74a-74e to identify which of the detailed images 74a-74e is being displayed. Each of the identification images 82a-82e is composed of the same number of objects (e.g., circular objects) as the number of detailed images 74a-74e belonging to one process group. In the example shown in Figures 6(a)-(e), each of the identification images 82a-82e includes five objects corresponding to the five detailed images 74a-74e.

[0043] The first identification image 82a superimposed on the first detailed image 74a includes one white object and four black objects, indicating that it is the first image based on the number of white objects. The second identification image 82b superimposed on the second detailed image 74b includes two white objects and three black objects, indicating that it is the second image based on the number of white objects. Similarly, the third identification image 82c superimposed on the third detailed image 74c includes three white objects, indicating that it is the third image. The fourth identification image 82d superimposed on the fourth detailed image 74d includes four white objects, indicating that it is the fourth image. The fifth identification image 82e superimposed on the fifth detailed image 74e includes five white objects, indicating that it is the fifth image. Note that the identification images 82a to 82e may indicate their image numbers using letters or numbers instead of the number of objects, for example, by displaying "1 / 5" to indicate that it is the first of five images.

[0044] The switching display of two or more detailed images 74a-74e is repeated until a predetermined condition is satisfied. The switching display of two or more detailed images 74a-74e may be stopped and started in response to a user operation. For example, the switching display may be paused by a user operation of touching the display area of ​​the switching-displayed detailed images 74a-74e. The switching display may also be resumed by a user operation of touching the display area of ​​the paused detailed images 74a-74e again. When the switching display is started, the switching display may be resumed from the detailed image displayed during the pause. For example, if the display is paused while the second detailed image 74b is being displayed, the third detailed image 74c, which is the image next to the second detailed image 74b, may be displayed after resumption. When the switching display is resumed, the switching display may be resumed from the beginning, i.e., from the first detailed image 74a, regardless of which detailed image was displayed during the pause. In this case, by a user operation of touching the display area of ​​the detailed images 74a to 74e twice in succession, the switching display of the detailed images 74a to 74e can be reset and the switching display can be resumed from the initial first detailed image 74a.

[0045] While two or more detailed images 74a to 74e are alternately displayed, the display state of the overall image 72 and the incidental image 76 is maintained. For example, in the explanation screen 70 for the first step group shown in Figure 4, with the incidental image 76 displayed at a position corresponding to the arterial pressure port 32 and the main line clamp 36 in the overall image 72, the detailed images 74a to 74e shown in Figures 6(a) to 6(e) are alternately displayed in a predetermined order. In other words, while the detailed images 74a to 74e are alternately displayed in a predetermined order, the position at which the incidental image 76 is superimposed on the overall image 72 is fixed.

[0046] The explanation screen 70 explaining the first step group ends when a predetermined condition related to the execution of at least one step included in the first step group is satisfied, and switches to the explanation screen 70 explaining the next, second step group. The explanation screen 70 explaining the first step group ends when a sensor detects the execution of at least one step included in the first step group. The explanation screen 70 explaining the first step group can end, for example, when the arterial side sensor 36a of the main line clamp 36 detects that the arterial blood circuit 52 has been set in the main line clamp 36 in the step corresponding to the fourth detailed image 74d.

[0047] The explanation screen 70 for explaining the first step group may be terminated immediately after the arterial sensor 36a detects the arterial side, or may be terminated after a predetermined waiting time has elapsed since the arterial sensor 36a detected the arterial side. For example, the length of the waiting time from sensor detection until the explanation screen 70 is changed may be set taking into account the work time of the step executed after the sensor detects the arterial side. For example, in the case of the first step group, the waiting time may be set taking into account the work time of the step corresponding to the fifth detailed image 74e executed after the arterial sensor 36a detects the arterial side. The length of the waiting time may be set to be equal to or longer than the switching cycle of the detailed images 74a to 74e. The switching cycle of the detailed images 74a to 74e is, for example, approximately 5 to 10 seconds, and the length of the waiting time may also be set to be equal to or longer than the switching cycle of the detailed images 74a to 74e. By terminating the explanation screen 70 after a waiting time set to be equal to or longer than the switching cycle of the detailed images 74a to 74e has elapsed, it is possible to ensure that the detailed images 74a to 74e are switched at least once before the explanation screen 70 is terminated.

[0048] The display time of each of the detailed images 74a-74e in one switching cycle may be the same or may differ for each image. The display time of each of the detailed images 74a-74e in one switching cycle is, for example, approximately 1 to 3 seconds. The display time of each of the detailed images 74a-74e in one switching cycle may be the same as the display cycle of the incidental image 76, or may be shorter or longer than the display cycle of the incidental image 76. As an example, the display time of the first detailed image 74a is 2 seconds, the display time of the second detailed image 74b, the third detailed image 74c, and the fourth detailed image 74d is 1.5 seconds, and the display time of the fifth detailed image 74e is 2 seconds. The display time of each of the detailed images 74a-74e can be set taking into consideration the time required for the process corresponding to each of the detailed images 74a-74e.

[0049] FIG. 7 shows an example of an explanatory screen 70 for explaining the second group of steps. The overall image 72 used to explain the second group of steps is the same as the overall image 72 used to explain the first group of steps in FIG. 4 . An accessory image 76 is superimposed on the overall image 72 at a position where the blood pump 30 and the fluid replacement line clamp 34 are depicted, and is superimposed at a position different from the accessory image 76 in FIG. 4 . The detailed image 74 corresponds to at least one step included in the second group of steps and is different from the detailed images 74, 74a-74e used to explain the first group of steps shown in FIG. 4 and FIGS. 6(a)-(e).
