[0025] The control unit 60 controls the overall operation of the medical device 10 according to a program, for example, by the processor 60a executing the program stored in the memory 60b. The processor 60a may execute a program stored in an arbitrary storage device different from the memory 60b, may execute a program acquired from an arbitrary recording medium by a reading device, or may execute a program acquired via a network. The memory 60b in which the program is stored may be a volatile memory such as a DRAM (Dynamic Random Access Memory), or may be a non-volatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory), a flash memory, a magnetoresistive memory, a resistive random access memory, or a ferroelectric memory. Non-volatile memories, magnetic recording media such as magnetic tapes and magnetic disks, and optical recording media such as optical disks are examples of storage media that are non-transitory and tangible and computer readable.

[0026] The control unit 60 is connected to various devices (such as sensors) provided in the main body 12 via, for example, the system bus 62. The control unit 60 acquires a signal from the holding sensor 22a provided in the coupler holder 22. The holding sensor 22a detects whether or not the dialysate coupler 26 is set in the coupler holder 22. The control unit 60 acquires a signal from the empty liquid sensor 28. The empty liquid sensor 28 detects whether or not there is liquid inside the replenishing liquid line 56. The control unit 60 acquires a signal from the cover opening / closing sensor 30a provided in the blood pump 30. The cover opening / closing sensor 30a detects the opening and closing of the cover provided in the blood pump 30. The control unit 60 acquires a signal from the push sensor 34a provided in the replenishing liquid line clamp 34. The push sensor 34a detects the pressing of a push button operated to attach the replenishing liquid line 56 to the replenishing liquid line clamp 34.

[0027] The control unit 60 acquires signals from the arterial side sensor 36a and the venous side sensor 36b provided in the main line clamp 36. The arterial side sensor 36a detects whether or not the arterial side blood circuit 52 is set in the main line clamp 36. The arterial side sensor 36a may include a sensor that detects the presence or absence of air bubbles or blood flowing through the arterial side blood circuit 52. The venous side sensor 36b detects whether or not the venous side blood circuit 54 is set in the main line clamp 36. The venous side sensor 36b may include a sensor that detects the presence or absence of air bubbles or blood flowing through the venous side blood circuit 54. The control unit 60 acquires a signal from the cover opening / closing sensor 38a provided in the blood volume monitor 38. The cover opening / closing sensor 38a detects the opening and closing of the cover provided in the blood volume monitor 38. The control unit 60 acquires a signal from the lever opening / closing sensor 46a provided in the drain port 46. The lever opening / closing sensor 46a detects the opening and closing of the lever provided in the drain port 46.

[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 a signal from a touch sensor 14a provided in the display unit 14. The touch sensor 14a detects a user operation on the display unit 14. The control unit 60 causes the display unit 14 to display an image stored in the memory 60b or the storage device 60c. The control unit 60 shows, in order of steps, the attachment procedure for attaching a consumable to the main body unit 12 by changing, switching, or updating the image to be displayed on the display unit 14 based on signals from various sensors, for example.

[0029] FIG. 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 attached image 76, and an explanatory text 78.

[0030] The overall image 72 is an image depicting the state of the front surface of the main body unit 12 and is an image depicting a plurality of attachment portions to which consumables are attached. The overall image 72 shows, for example, the front surface of the main body unit 12 in a state where all consumables are attached and the attachment procedure is completed. For example, the overall image 72 shown in FIG. 4 includes a blood purifier 50, an arterial side blood circuit 52, a venous side blood circuit 54, a fluid infusion line 56, etc., attached to the main body unit 12. The overall image 72 may show the front surface of the main body unit 12 in a state where no consumable is attached, or may show the front surface of the main body unit 12 in an intermediate state where some consumables are attached. The overall image 72 may not be switched and displayed according to the progress of the attachment procedure and may be common over a plurality of steps constituting the attachment procedure.

[0031] The detailed image 74 is an image depicting the state of at least one of the plurality of steps constituting the attachment procedure. The detailed image 74 is switched and displayed according to the progress of the attachment procedure, and shows the details of the step that the user should work on at the current time. The detailed image 74 shows the main body 12 when viewed from a different perspective from the overall image 72, and shows, for example, a left perspective view or a right perspective view of the main body 12. The detailed image 74 may show an enlarged view of the part where the user should work, and may show the empty liquid sensor 28, the replenishing liquid bag 58, etc. that are not shown in the overall image 72. The detailed image 74 may show the part where the user should work in a display mode different from other parts. For example, the part where the user should work may be color-displayed, and other parts may be grayed out. For example, the detailed image 74 shown in FIG. 4 shows the step of attaching the pressure pod 52b of the arterial blood circuit 52 to the arterial side pressure port 32. The arterial blood circuit 52 and the pressure pod 52b are displayed in red, and the other parts are grayed out. The detailed image 74 is displayed in an area different from the overall image 72 and is displayed so as not to overlap with the overall image 72.

[0032] The attached image 76 is an image that is superimposed and displayed on a part of the overall image 72 or the detailed image 74. The attached image 76 is displayed to emphasize a specific part of the overall image 72 or the detailed image 74. The attached image 76 is displayed in a part related to at least one step shown in the detailed image 74, and is displayed at the position where the attachment part and the consumable related to at least one step are drawn. The attached image 76 may be displayed only in one part, or may be simultaneously displayed in each of a plurality of parts. The attached image 76 shown in FIG. 4 is displayed at the position where the arterial side pressure port 32 is drawn and the position where the main line clamp 36 is drawn in the overall image 72. These correspond to the step of attaching the pressure pod 52b to the arterial side 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 attached image 76 is changed or updated according to the progress of the attachment procedure. For example, the displayed position is changed according to the progress of the attachment procedure.

[0033] The attached image 76 preferably has a display mode that can be easily distinguished from the consumables and attachment parts shown in the overall image 72 and the detailed image 74. The attached image 76 preferably has a simple shape such as a circle, an ellipse, a polygon, or a star. The attached image 76 preferably has a display color different from the display colors (e.g., red or blue) used in the overall image 72 and the detailed image 74, and can have, for example, a display color such as yellow or green. The attached image 76 may be configured such that the display size and the display color change periodically. The attached image 76 may be displayed in a blinking manner. The attached image 76 may have a transparent (e.g., semi-transparent) display mode for the visibility of the overlapping parts.

[0034] Figs. 5(a) to (f) are diagrams showing an example of the display process of the attached image 76. As time passes, 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 of the attached image 76 are displayed in order, and after the display of the sixth image 76f, it returns to the first image 76a. The attached images 76a to 76f are configured such that the display size increases as time passes, while the display color becomes lighter (or the transparency increases) as time passes. The time change rates of the display size and the display color may be constant or may change as time passes. The display cycle of the attached images 76a to 76f is, for example, about 1 second to 2 seconds. One display cycle of the attached images 76a to 76f may have an interval period during which the attached image 76 is not displayed. The interval period may be provided after the display of the sixth image 76f and before returning to the first image 76a.

[0035] Returning to Fig. 4, the explanatory text 78 is a string or passage that explains at least one process shown in the detailed image 74. The explanatory text 78 is displayed in a region 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. In the explanatory text 78 shown in Fig. 4, it is described that "Attach the blood purifier and the replenishing fluid bag. Set the arterial side blood circuit to the pressure pod and the main line clamp (the groove on the left side).", which corresponds to the process shown in the detailed image 74.

[0036] The explanation screen 70 can 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, since the installation work of the consumables is not completed, the operation of the start button is not possible, and the start button image 80 is displayed in a grayed-out state.

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

[0038] FIGS. 6(a) to (e) are diagrams showing an example of the display process of the detailed images 74a to 74e, and show the display process of the detailed image 74 simultaneously displayed with the overall image 72 in the explanation screen 70 of the first process group shown in FIG. 4. As time passes, the first detailed image 74a, the second detailed image 74b, the third detailed image 74c, the fourth detailed image 74d, and the fifth detailed image 74e of the detailed image 74 are sequentially displayed, and after the display of the fifth detailed image 74e, it returns to the first detailed image 74a.

[0039] The first detailed image 74a in FIG. 6(a) shows the process of attaching the blood purifier 50 and the replenishing fluid bag 58. The blood purifier 50 and the replenishing fluid bag 58 are color-displayed, and the other parts are grayed out. The second detailed image 74b in FIG. 6(b) shows the process of opening the cover of the main line clamp 36, and the main line clamp 36 with the cover opened is color-displayed. Also, in the second detailed image 74b, the arterial side pressure port 32 to be noted in the process of the next third detailed image 74c is also color-displayed.

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

[0041] The fifth detailed image 74e in Fig. 6(e) shows the step of winding the excess of the arterial side blood circuit 52 extending below the main line clamp 36 around the tube hook 48 for temporary holding. In the fifth detailed image 74e, the arterial side blood circuit 52 and the purifier - side end 52e wound around the tube hook 48 are color - displayed.

[0042] Identification images 82a - 82e for identifying which of the detailed images 74a - 74e are being displayed are superimposed on the detailed images 74a - 74e. The identification images 82a - 82e are composed of the same number of objects (for example, circular objects) as the number of detailed images 74a - 74e belonging to one process group. In the example shown in Fig. 6(a) - (e), the identification images 82a - 82e include 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, and indicates that it is the first by 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, and indicates that it is the second by the number of white objects. Similarly, the third identification image 82c superimposed on the third detailed image 74c is indicated as the third by three white objects. The fourth identification image 82d superimposed on the fourth detailed image 74d is indicated as the fourth by four white objects. The fifth identification image 82e superimposed on the fifth detailed image 74e is indicated as the fifth by five white objects. Note that the identification images 82a to 82e may indicate the image numbers by letters or numbers instead of the number of objects. For example, it may be indicated as the first out of five by the display of "1 / 5".

[0044] The switching display of two or more detailed images 74a to 74e is repeated until a predetermined condition is satisfied. The switching display of two or more detailed images 74a to 74e may be stopped and started according to a user operation. For example, the switching display may be temporarily stopped by a user operation of touching the display area of the detailed images 74a to 74e to be switched. Also, the switching display may be resumed by a user operation of touching the display area of the detailed images 74a to 74e that have been temporarily stopped again. When starting the switching display, the switching display may be resumed from the detailed image displayed during the temporary stop. For example, when temporarily stopped during the display of the second detailed image 74b, the third detailed image 74c following the second detailed image 74b may be displayed after resumption. When resuming the switching display, regardless of which detailed image was displayed during the temporary stop, the switching display may be resumed from the beginning, that is, from the first first detailed image 74a. In this case, the switching display of the detailed images 74a to 74e can be reset by a user operation of continuously touching the display area of the detailed images 74a to 74e twice, and the switching display can be resumed from the first first detailed image 74a.

[0045] While two or more detailed images 74a to 74e are switched and displayed, the display states of the overall image 72 and the supplementary image 76 are maintained. For example, in the explanation screen 70 of the first process group shown in FIG. 4, while the supplementary image 76 is displayed at positions corresponding to the arterial pressure port 32 and the main line clamp 36 of the overall image 72, the detailed images 74a to 74e shown in FIGS. 6(a) to (e) are switched and displayed in a predetermined order. That is, while the detailed images 74a to 74e are switched and displayed in a predetermined order, the position where the supplementary image 76 is superimposed on the overall image 72 is fixed.

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

[0047] The explanation screen 70 for explaining the first process group may end immediately after the detection by the arterial side sensor 36a, or may end after a predetermined waiting time has elapsed since the detection by the arterial side sensor 36a. For example, the length of the waiting time until the explanation screen 70 is changed from the detection of the sensor may be set in consideration of the working time of the process executed after the detection of the sensor. For example, in the case of the first process group, the waiting time may be set in consideration of the working time of the process corresponding to the fifth detailed image 74e executed after the detection by the arterial side sensor 36a. The length of the waiting time may be set to be equal to or longer than the switching period of the detailed images 74a to 74e. The switching period of the detailed images 74a to 74e is, for example, about 5 seconds to 10 seconds, and the length of the waiting time can also be set to about 5 seconds to 10 seconds. By ending the explanation screen 70 after the elapse of the waiting time set to be equal to or longer than the switching period of the detailed images 74a to 74e, it is possible to ensure that the switching display of the detailed images 74a to 74e is executed at least once before the end of the explanation screen 70.

[0048] The display time of each of the detailed images 74a to 74e in one switching period may be the same, or may be different for each image. The display time of each of the detailed images 74a to 74e in one switching period is, for example, about 1 second to 3 seconds. The display time of each of the detailed images 74a to 74e in one switching period may be the same as the display period of the accompanying image 76, may be shorter than the display period of the accompanying image 76, or may be longer. As an example, the display time of the first detailed image 74a is 2 seconds, the display time of each 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 to 74e can be set in consideration of the time required for the process corresponding to each of the detailed images 74a to 74e.

[0049] FIG. 7 is a diagram showing an example of an explanation screen 70 for explaining the second process group. The overall image 72 used for explaining the second process group is the same as the overall image 72 used for explaining the first process group in FIG. 4. The supplementary image 76 is superimposed on the overall image 72 at a position where the blood pump 30 and the replenishing fluid line clamp 34 are drawn, and is superimposed at a position different from the supplementary image 76 in FIG. 4.
