The dialysate outlet 50d is connected to the discharge-side dialysate tubing 24a via a discharge-side connector 26a.

[0039] The blood purifier 50 has hollow fibers housed within it. The interior of the hollow fibers forms the blood flow path connecting the blood inlet 50a and the blood outlet 50b. The exterior of the hollow fibers forms the dialysate flow path connecting the dialysate inlet 50c and the dialysate outlet 50d. Numerous tiny pores (pores) are formed within the hollow fibers, allowing metabolites or excess water in the blood to pass through the dialysate.

[0040] The arterial-side blood circuit 52 is a blood outlet tube connecting the patient's artery and the blood purifier 50. The arterial-side blood circuit 52 is installed in the blood pump 30, arterial-side pressure interface 32, main line clamp 36, and blood volume monitor 38. In the middle of the arterial-side blood circuit 52, a Y-connector 52a, a pressure monitoring box 52b, and a pump body section 52c are provided. A branch of the infusion line 56 is connected to the Y-connector 52a. The pressure monitoring box 52b is installed in the arterial-side pressure interface 32, which measures arterial pressure. The pump body section 52c is installed in the blood pump 30, which straightens the tubing to allow blood flow. The patient-side end 52d of the arterial-side blood circuit 52 is connected to the patient's artery during dialysis treatment and to the outlet 46 during pre-filling. The purifier-side end 52e of the arterial-side blood circuit 52 is connected to the blood inlet 50a of the blood purifier 50.

[0041] The venous-side blood circuit 54 is a blood return tube connecting the blood purifier 50 to the patient's vein. The venous-side blood circuit 54 is installed in the main line holder 36, blood volume monitor 38, venous-side pressure interface 40, and venous-side line support 44. A gas trapping chamber 54a and a pressure monitoring box 54b are located in the middle of the venous-side blood circuit 54. The gas trapping chamber 54a is located between the main line holder 36 and the venous-side line support 44. The pressure monitoring box 54b is installed in the venous-side pressure interface 40 for measuring venous pressure. The purifier-side end 54c of the venous-side blood circuit 54 is connected to the blood outlet 50b of the blood purifier 50. The patient-side end 54d of the venous-side blood circuit 54 is connected to the patient's vein during dialysis treatment, but connected to the drain port 46 during priming.

[0042] The replenishment line 56 is a tube that supplies replenishment fluid used in pre-filling. The replenishment line 56 is connected to the replenishment bag 58 suspended by the replenishment hook 20. The replenishment line 56 is mounted on the replenishment line holder 34. A drip chamber 56a is provided in the middle of the replenishment line 56. An empty / liquid sensor 28 is installed between the drip chamber 56a and the replenishment bag 58.

[0043] Figure 2 Although not illustrated, a syringe for injecting heparin (an anticoagulant) can be mounted on the heparin pump 42. The heparin syringe is connected, for example, to a heparin line branching from the arterial side blood circuit 52 located between the blood pump 30 and the blood volume monitor 38.

[0044] Figure 3This is a block diagram schematically illustrating the functional configuration of a medical device 10. The medical device 10 includes a control unit 60. The control unit 60 includes a processor 60a such as a CPU (Central Processing Unit), a memory 60b such as RAM (Random Access Memory) or ROM (Read Only Memory), and a storage device 60c such as a HDD (Hard Disk Drive) or SSD (Solid State Drive).

[0045] The control unit 60, for example, executes a program stored in the memory 60b via a processor 60a, and controls all operations of the medical device 10 according to the program. The processor 60a can execute programs stored in any storage device different from the memory 60b, programs retrieved from any recording medium by a reading device, or programs retrieved via a network. The memory 60b storing the program can be a volatile memory such as DRAM (Dynamic Random Access Memory), or a non-volatile memory such as EEPROM (Electrically Erasable Programmable Read-Only Memory), flash memory, magnetoresistive memory, resistive alternating current memory, or ferroelectric memory. Non-volatile memory, magnetic recording media such as magnetic tape and disk, and optical recording media such as optical discs are examples of non-transitory and tangible computer-readable storage media.

[0046] The control unit 60 is connected, for example, via the system bus 62 to various devices (e.g., sensors) installed on the main body 12. The control unit 60 receives signals from a holding sensor 22a installed on the connector holder 22. The holding sensor 22a detects whether a dialysate connector 26 is installed on the connector holder 22. The control unit 60 receives signals from an empty-liquid sensor 28. The empty-liquid sensor 28 detects whether there is liquid inside the refill line 56. The control unit 60 receives signals from a cap opening / closing sensor 30a installed on the blood pump 30. The cap opening / closing sensor 30a detects the opening and closing of the cap installed on the blood pump 30. The control unit 60 receives signals from a press sensor 34a installed on the refill line holder 34. The press sensor 34a detects the pressing of a button operated to install the refill line 56 onto the refill line holder 34.

[0047] The control unit 60 acquires signals from the arterial side sensor 36a and the venous side sensor 36b disposed on the main cable holder 36. The arterial side sensor 36a detects whether an arterial side blood circuit 52 is provided in the main cable holder 36. The arterial side sensor 36a may also include a sensor that detects the presence or absence of air bubbles or blood flowing in the arterial side blood circuit 52. The venous side sensor 36b detects whether a venous side blood circuit 54 is provided in the main cable holder 36. The venous side sensor 36b may also include a sensor that detects the presence or absence of air bubbles or blood flowing in the venous side blood circuit 54. The control unit 60 acquires signals from the cap opening / closing sensor 38a disposed on the blood volume monitor 38. The cap opening / closing sensor 38a detects the opening and closing of the cap disposed on the blood volume monitor 38. The control unit 60 acquires signals from the lever opening / closing sensor 46a disposed on the discharge port 46. The lever opening / closing sensor 46a detects the opening and closing of the lever disposed on the discharge port 46.

[0048] The control unit 60 is connected to the display unit 14, for example, via the system bus 62. The control unit 60 controls the display content of the display unit 14. The control unit 60 acquires signals from the 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 the display unit 14 to display images stored in the memory 60b or storage device 60c. The installation steps, in sequence, are shown in which the control unit 60 changes, switches, or updates the images displayed on the display unit 14 based on signals from various sensors, thereby installing consumables on the main body 12.

[0049] Figure 4 This is a diagram showing an example of the explanatory screen 70 displayed on the display unit 14. The explanatory screen 70 includes an overall image 72, a detailed image 74, an accompanying image 76, and explanatory text 78.

[0050] Overall image 72 is an image depicting the state of the front surface of the main body 12, and is an image depicting multiple mounting parts on which consumables are installed. Overall image 72 shows, for example, the front surface of the main body 12 in a state where all consumables are installed and the installation process is completed. For example, Figure 4 The overall image 72 shown includes the blood purifier 50, arterial blood circuit 52, venous blood circuit 54, and infusion tubing 56, all installed on the main body 12. The overall image 72 can show the front surface of the main body 12 without consumables installed, or it can show the front surface of the main body 12 in an intermediate state with some consumables installed. The overall image 72 can also be displayed consistently across multiple steps constituting the installation process, without switching according to the progress of the installation steps.

[0051] Detailed image 74 is an image depicting the state of at least one of the multiple steps constituting the installation process. Detailed image 74 switches its display according to the progress of the installation process, showing details of the step the user should perform at the current moment. Detailed image 74 shows the main body 12 viewed from a different perspective than the overall image 72, showing, for example, a left perspective view or a right perspective view of the main body 12. Detailed image 74 may show enlarged views of the parts the user should operate, or it may show elements not shown in the overall image 72, such as the air / liquid sensor 28 or the replenishment bag 58. Detailed image 74 may display the parts the user should operate in a different display mode than other parts, for example, displaying the parts to be operated in color and other parts in grayscale. For example, Figure 4 Detailed image 74 shows the process of installing the pressure monitoring box 52b of the arterial side blood circuit 52 at the arterial side pressure interface 32. The arterial side blood circuit 52 and the pressure monitoring box 52b are shown in red, while other parts are shown in gray. Detailed image 74 is displayed in a different area from the overall image 72 in a manner that does not overlap with the overall image 72.

[0052] The accompanying image 76 is an image superimposed on a portion of the overall image 72 or the detailed image 74. The accompanying image 76 is displayed to emphasize a specific portion of the overall image 72 or the detailed image 74. The accompanying image 76 shows the portion shown in the detailed image 74 that is related to at least one process, showing the location depicting an installation part or consumable related to at least one process. The accompanying image 76 may show only one portion, or it may show multiple portions simultaneously. Figure 4 The accompanying image 76 shows the location of the arterial side pressure interface 32 and the location of the mainline clamp 36 within the overall image 72. These correspond to the steps of installing the pressure monitoring box 52b on the arterial side pressure interface 32 as shown in detailed image 74, and the steps of installing the arterial side blood circuit 52 on the mainline clamp 36 as shown in detailed image 74. The accompanying image 76 may be modified or updated according to the progress of the installation steps, for example, the displayed location may change depending on the progress of the installation steps.

[0053] The accompanying image 76 preferably has a display method that allows for easy differentiation between the consumable or mounting part shown in the overall image 72 or the detailed image 74. The accompanying image 76 preferably has a simple shape such as a circle, ellipse, polygon, or star. The accompanying image 76 preferably has a display color different from the display color (e.g., red or blue) used in the overall image 72 or the detailed image 74, and may have a display color such as yellow or green. The accompanying image 76 may also be configured to periodically change in display size or display color. The accompanying image 76 may also be displayed in a flashing manner. For the identification of overlapping portions, the accompanying image 76 may have a translucent (e.g., semi-transparent) display method.

[0054] Figure 5 Figures (a) to (f) illustrate an example of the display process of the accompanying image 76. The accompanying image 76 displays, sequentially over time, a first image 76a, a second image 76b, a third image 76c, a fourth image 76d, a fifth image 76e, and a sixth image 76f, returning to the first image 76a after the sixth image 76f is displayed. The accompanying images 76a to 76f are configured such that their display size increases over time, but their display color becomes lighter (or their transparency increases) over time. The rate of change of the display size or display color over time can be constant or it can vary over time. The display cycle of the accompanying images 76a to 76f is, for example, approximately 1 to 2 seconds. One display cycle of the accompanying images 76a to 76f may include an interval period during which the accompanying image 76 is not displayed. This interval period can be set after the display of the sixth image 76f and before the return to the first image 76a.

[0055] return Figure 4 Description text 78 is a string or text describing at least one process shown in detailed image 74. Description text 78 is displayed in an area different from the overall image 72 and detailed image 74, in a manner that does not overlap with the overall image 72 and detailed image 74. Figure 4 The explanatory text 78 shows the procedure of "Installing the blood purifier and infusion bag. Setting the arterial blood circuit in the pressure monitoring box and mainline clamp (slot on the left)." This corresponds to the procedure shown in detailed image 74.

[0056] The explanatory screen 70 may also include a start button image 80. The start button image 80 is an operation button used to begin pre-charging, becoming operable upon completion of the consumable installation process. Figure 4 In the explanatory screen 70 shown, the start button cannot be operated because the installation of consumables has not been completed. The start button image 80 is grayed out.

[0057] The explanatory screen 70 is prepared, for example, for a process group containing two or more related processes. In the explanatory screen 70 explaining the first process group, an accompanying image 76 is displayed overlaid on a portion of the overall image 72 related to the two or more processes included in the first process group. Two or more detailed images 74 are displayed in turn 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 predetermined order. Screen numbers can also be labeled for each process group in the explanatory screen 70.

[0058] Figure 6 Figures (a) to (e) are examples illustrating the display process of detailed images 74a to 74e. Figure 4The explanatory screen 70 for the first process group shows the display process of detailed images 74, which are displayed simultaneously with the overall image 72. Detailed images 74 are displayed sequentially over time: first detailed image 74a, second detailed image 74b, third detailed image 74c, fourth detailed image 74d, and fifth detailed image 74e. After displaying the fifth detailed image 74e, the display returns to the first detailed image 74a.

[0059] Figure 6 The first detailed image 74a of (a) shows the process of installing the blood purifier 50 and the infusion bag 58, with the blood purifier 50 and the infusion bag 58 shown in color and the other parts shown in gray. Figure 6 The second detailed image 74b of (b) shows the process of opening the cover of the mainline clamp 36, with the mainline clamp 36 in the open state shown in color. Furthermore, in the second detailed image 74b, the arterial side pressure interface 32, which should be of focus in the next third detailed image 74c, is also shown in color.

[0060] Figure 6 The third detailed image 74c shows the process of installing the pressure monitoring box 52b at the arterial side pressure interface 32 and the arterial side blood circuit 52 at the mainline holder 36. In the third detailed image 74c, the installed arterial side blood circuit 52 is shown in color. Figure 6 The fourth detailed image 74d of (d) shows the process of closing the cover of the mainline clamp 36, with the mainline clamp 36 in the closed state shown in color.

[0061] Figure 6 Fifth detailed image 74e of (e) shows the process of winding the remaining portion of the arterial side blood circuit 52, which extends downward toward the main line holder 36, around the hook 48 and temporarily holding it in place. In fifth detailed image 74e, the arterial side blood circuit 52 wound around the hook 48 and the purifier side end 52e are shown in color.

[0062] In detailed images 74a-74e, identification images 82a-82e are overlaid to identify which of the detailed images 74a-74e is currently displayed. Identification images 82a-82e consist of the same number of objects (e.g., circular objects) as the number of detailed images 74a-74e belonging to a process group. Figure 6 In the examples shown in (a) to (e), the recognition images 82a to 82e contain five objects corresponding to the five detailed images 74a to 74e.

[0063] The first recognition image 82a, superimposed on the first detailed image 74a, contains one white object and four black objects; the number of white objects indicates that it is the first image. The second recognition image 82b, superimposed on the second detailed image 74b, contains two white objects and three black objects; the number of white objects indicates that it is the second image. Similarly, the third recognition image 82c, superimposed on the third detailed image 74c, is the third image with three white objects. The fourth recognition image 82d, superimposed on the fourth detailed image 74d, is the fourth image with four white objects. The fifth recognition image 82e, superimposed on the fifth detailed image 74e, is the fifth image with five white objects. Furthermore, the recognition images 82a-82e may not be identified by the number of objects, but rather by text or numbers indicating the image number; for example, displaying "1 / 5" indicates the first of five images.

[0064] The switching display of two or more detailed images 74a-74e is repeated until a predetermined condition is met. The switching display of two or more detailed images 74a-74e can be stopped and started according to user operation. For example, the switching display can be temporarily stopped by touching the display area of ​​the switched detailed images 74a-74e. Furthermore, the switching display can be restarted by touching the display area of ​​the temporarily stopped detailed images 74a-74e again. When restarting the switching display, it can resume from the detailed image displayed during the temporary stop. For example, if the switching was temporarily stopped during the display of the second detailed image 74b, the next third detailed image 74c after the second detailed image 74b can be displayed after restarting. When restarting the switching display, regardless of which detailed image was displayed during the temporary stop, the switching display can resume from the initial, i.e., the first detailed image 74a. At this time, by touching the display area of ​​the detailed images 74a-74e twice consecutively, the switching display of the detailed images 74a-74e can be reset, and the switching display can resume from the initial first detailed image 74a.

[0065] During the switching between displaying two or more detailed images 74a-74e, the display state of the overall image 72 and the accompanying image 76 is maintained. For example, in Figure 4 In the explanatory screen 70 of the first process group shown, the accompanying image 76 is displayed at the position corresponding to the arterial side pressure interface 32 and the main cable holder 36 in the overall image 72. Figure 6 The detailed images 74a-74e shown in (a) to (e) are displayed in a predetermined order. That is, during the display of detailed images 74a-74e in a predetermined order, the position of the overlapping accompanying image 76 in the overall image 72 is fixed.

[0066] The explanatory screen 70 for the first process group ends when a specified condition related to the execution of at least one process included in the first process group is met, and the screen switches to the explanatory screen 70 for the next second process group. The explanatory screen 70 for the first process group ends when a sensor detecting the execution of at least one process included in the first process group is detected. The explanatory screen 70 for the first process group may, for example, end when the arterial side sensor 36a of the main cable holder 36 is detected. In the process corresponding to the fourth detailed image 74d, the arterial side sensor 36a of the main cable holder 36 detects that an arterial side blood circuit 52 is provided in the main cable holder 36.

[0067] The explanation screen 70 for the first process group can end after the arterial side sensor 36a is detected, or it can end after a predetermined standby time has elapsed since the detection of the arterial side sensor 36a. For example, the length of the standby time from the detection of the sensor until the explanation screen 70 is changed can be set taking into account the operation time of the process executed after the sensor detection. For example, for the first process group, the standby time can be set taking into account the operation time of the process corresponding to the fifth detailed image 74e executed after the detection of the arterial side sensor 36a. The length of the standby time can be set to be greater than or equal to the switching cycle of detailed images 74a to 74e. The switching cycle of detailed images 74a to 74e is, for example, about 5 to 10 seconds, and the length of the standby time can also be set to be around 5 to 10 seconds. After the standby time, which is set to be greater than or equal to the switching cycle of detailed images 74a to 74e, has elapsed, the explanation screen 70 ends, and the switching display of detailed images 74a to 74e can be ensured to be executed at least once before the explanation screen 70 ends.

[0068] The display time for each detailed image 74a-74e in a single switching cycle can be common or different for each image. For example, the display time for each detailed image 74a-74e in a single switching cycle can be approximately 1 to 3 seconds. The display time for each detailed image 74a-74e in a single switching cycle can be the same as, shorter than, or longer than the display cycle of the accompanying image 76. As an example, the display time for the first detailed image 74a is 2 seconds, the display time for the second detailed image 74b, the third detailed image 74c, and the fourth detailed image 74d is 1.5 seconds each, and the display time for the fifth detailed image 74e is 2 seconds. The display time for each detailed image 74a-74e can be set considering the time required for the corresponding process.
