[0002] Conventionally, hemodialysis treatment (hereinafter simply referred to as dialysis treatment) for dialysis patients is performed using a dialysis machine installed at the bedside of the dialysis patient. In dialysis treatment, it is important to set appropriate conditions according to the patient's blood condition, in particular to control the water removal speed. Therefore, a hemodialysis device has been disclosed that can easily set hemodialysis treatment conditions adapted to each patient over time, particularly the water removal rate, while monitoring the blood condition of each patient (see, for example, Patent Document 1).

[0031] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (First embodiment) [Dialysis machine 1] FIG. 1 is a diagram showing functional blocks of a dialysis device 1 according to the first embodiment. FIG. 2 is a diagram showing an example of the patient dialysis status data storage unit 32 of the dialysis device 1 according to the first embodiment.

[0032] The dialysis machine 1 is installed at a medical institution, such as at the bedside of a patient undergoing dialysis treatment, and is a machine that performs dialysis treatment for the patient. As shown in FIG. 1, the dialysis machine 1 includes a control unit 10, a storage unit 30, an operation display panel 36 (display unit), operation buttons 37, various pumps 38, and various measuring devices 39. The control unit 10 is a central processing unit (CPU) that controls the dialysis machine 1. The control unit 10 appropriately reads and executes an operating system (OS) and application programs stored in the storage unit 30, thereby cooperating with the above-mentioned hardware and executing various functions.

[0033] Before describing the control unit 10, the storage unit 30 will be described. The storage unit 30 is a storage area such as a hard disk, a semiconductor memory device, etc. for storing programs, data, etc. required for the control unit 10 to execute various processes. The memory unit 30 includes a program memory unit 31 and a patient dialysis status data memory unit 32 . The program storage unit 31 is a storage area for storing various programs, such as programs for executing various functions of the control unit 10, which will be described later. The programs stored in the program storage unit 31 include, for example, a BV (circulating blood volume) adjustment program, which will be described later. The programs stored in the program storage unit 31 may be separate programs for each functional unit or multiple functional units of the control unit 10, or may be a single program.

[0034] The patient dialysis status data storage unit 32 is a storage area for storing patient dialysis status data indicating the dialysis status of the patient. An example of each item stored in the patient dialysis status data storage unit 32 is shown in FIG. The patient dialysis status data memory unit 32 shown in Figure 2 has items including patient ID (IDentification), dialysis date and time, trend data, total amount of water removed at the end of dialysis, water removal rate at the start of dialysis, and set value. The patient ID is identification information for identifying a patient. The dialysis date and time is the date and time when the dialysis treatment started. The transition data is, for example, transition data of blood parameters indicating the state of blood, such as transition data of the rate of change of the circulating blood volume of the patient (for example, can be expressed as %BV△) and transition data of hematocrit measurement value. In addition to the above transition data, the transition data may include time series data indicating the transition of blood pressure, venous pressure, water removal amount, water removal speed, etc. The total amount of water removed at the end of dialysis is the total amount of water removed measured at the end of dialysis. The water removal rate at the start of dialysis is a preset water removal rate at the start of dialysis. The set values ​​are various patient-related values ​​that are set in the dialysis device 1, and may include at least one of values ​​related to the patient's weight, such as the patient's weight before and after dialysis, DW (dry weight), and target water removal volume, and may further include the treatment details, the patient's blood test results, etc.

[0035] The storage unit 30 also stores other designation conditions that are set in advance for the dialysis device 1, for example, designation conditions that indicate the range of data to be used as past data. In the example described below, three designation conditions are stored in the storage unit 30. The designation conditions are: (1) use of the most recently stored previous data, (2) use of the average value of multiple (e.g., three) past data sets including the most recently stored previous data set, and (3) use of past data sets that have the same timing in a periodic dialysis cycle. Here, the same timing in a periodic dialysis cycle corresponds to, for example, the same day of the week. The storage unit 30 may further include, for example, a patient information storage unit that stores basic information of a patient. The patient information storage unit may store basic information of a patient, such as the patient's name and date of birth, and a dialysis history, in association with a patient ID.

[0036] Next, the control unit 10 will be described. The control unit 10 includes a patient designation receiving unit 11 (patient designation receiving means), a setting proposal processing unit 12 (setting proposal device), a setting change receiving unit 25 (line change receiving means), a dialysis processing unit 26 (water removal rate control means), and a data storage processing unit 27. The patient designation receiving unit 11 receives designation of a patient (a patient to be dialysis treated) who will undergo dialysis treatment using the dialysis device 1. The patient designation receiving unit 11 receives, via the operation display panel 36, for example, a patient ID. The setting suggestion processing unit 12 suggests settings related to dialysis treatment for the patient. The setting proposal processing unit 12 includes a past data extraction unit 13, a threshold line setting unit 14 (threshold data setting means), a proposed graph output unit 15 (proposed graph output means), a smoothing receiving unit 16 (correction designation means), a smoothing processing unit 17 (smoothing means), and a proposed graph selection unit 18 (proposed graph receiving means).

[0037] The past data extraction unit 13 extracts the patient dialysis status data of the patient stored in the patient dialysis status data storage unit 32 based on the patient ID accepted by the patient designation acceptance unit 11. Here, the past data extraction unit 13 extracts the patient dialysis status data according to the designation conditions set in advance in the dialysis device 1 and stored in the storage unit 30. The past data extraction unit 13 extracts the patient's dialysis status data from the previous dialysis treatment that was stored in the past (most recently) in accordance with the specified condition (1) described above. Furthermore, the past data extraction unit 13 extracts multiple sets of patient dialysis status data, including the most recent data, stored in the past, in accordance with the specified condition (2) described above. Furthermore, the past data extraction unit 13 extracts past (most recent) dialysis status data of the patient having the same timing in the periodic dialysis cycle according to the specified condition (3) described above. In the following explanation, the specified conditions (1) to (3) are referred to as patterns 1 to 3.

[0038] The threshold line setting unit 14 sets alarm 1 lines (operation switching threshold lines) for controlling the change of the water removal speed for each of the three patterns (multiple patterns) based on the patient dialysis status data extracted by the past data extraction unit 13. Here, the alarm 1 line refers to a target line for the transition of the rate of change in circulating blood volume during dialysis treatment. The threshold line setting unit 14 may also set the values ​​of specific timings (specifically, for example, 60 minutes, 120 minutes, 180 minutes, and 240 minutes from the start of dialysis) of each alarm 1 line set by the threshold line setting unit 14 anew as each alarm 1 line. The proposed graph output unit 15 generates, for each pattern, a proposed graph including the alarm 1 line set by the threshold line setting unit 14 and a line indicating the patient dialysis status data used to set the alarm 1 line. Then, the proposed graph output unit 15 outputs the multiple proposed graphs generated for each pattern to the operation display panel 36. Furthermore, when the smoothing processing unit 17 generates each correction line, the proposed graph output unit 15 outputs a plurality of proposed graphs to the operation display panel 36, with the generated correction line as an alarm 1 line. Furthermore, the proposed graph output unit 15 may output again the values ​​of specific timings (specifically, for example, 60 minutes, 120 minutes, 180 minutes, and 240 minutes from the start of dialysis) of each correction line generated by the smoothing processing unit 17 as each alarm 1 line.

[0039] The smoothing reception unit 16 receives, via the operation display panel 36, a designation as to whether or not smoothing (smoothing) is to be performed on the alarm 1 line. In response to receiving a designation to perform smoothing from the smoothing receiving unit 16, the smoothing processing unit 17 performs a smoothing process (smoothing process) on each alarm 1 line to generate a correction line. The proposed graph selection unit 18 accepts, via the operation display panel 36, a selection operation for selecting one proposed graph from the multiple proposed graphs output by the proposed graph output unit 15.

[0040] The setting change receiving unit 25 receives, via the operation display panel 36, a change operation for the alarm 1 line of the proposed graph selected by the proposed graph selecting unit 18. The dialysis processing unit 26 executes dialysis processing. More specifically, the dialysis processing unit 26 performs processing for performing blood purification treatment using a blood purification circuit (not shown) having an arterial blood circuit and a venous blood circuit that constitute a blood circuit for circulating at least the patient's blood extracorporeally, and a blood purifier (not shown) having a plurality of connectors connectable to the blood purification circuit and for purifying the blood circulating extracorporeally in the blood circuit. As one of the processes, the dialysis processing unit 26 controls the water removal speed based on the relationship between the transition data of the circulating blood volume change rate, which can be measured by a hematocrit measuring device, which is one of various measuring devices 39 described later, and can be expressed as %BV△, and the alarm 1 line of the proposed graph selected by the proposed graph selection unit 18. In addition, when the setting change receiving unit 25 receives a change operation for the alarm 1 line, the dialysis processing unit 26 controls the water removal speed based on the relationship between the transition data of the circulating blood volume change rate and the changed alarm 1 line.

[0041] The data storage processing unit 27 stores various data related to the patient obtained by the dialysis treatment by the dialysis processing unit 26 in the patient dialysis status data storage unit 32. The various data related to the patient include, for example, transition data of blood parameters, as well as weight and DW before dialysis treatment, and may also include details of treatment during dialysis treatment.

[0042] The operation display panel 36 functions as an input device that is operated by touching with the operator's finger, and also functions as a display device. The operation button 37 is, for example, provided on a housing of the dialysis device 1 different from the operation display panel 36, and is a member used when performing operations related to the dialysis treatment. The various pumps 38 are pumps used in dialysis treatment, and include, for example, a blood pump, a fluid replacement pump, and a water removal pump. The various measuring devices 39 acquire values ​​related to the state of blood in the patient's body, and include a hematocrit measuring device, etc. The hematocrit measuring device measures values ​​such as the rate of change in circulating blood volume, a hematocrit measurement value, oxygen saturation, and PRR (Plasma Refilling Rate).

[0043] It should be noted that a computer refers to an information processing device equipped with a control unit, a storage device, etc., and the dialysis device 1 is an information processing device equipped with a control unit, a storage device, etc., and is included in the concept of a computer.

[0044] Next, the process in the dialysis device 1 will be described. [Settings proposal process] First, the process of administering dialysis treatment to a patient using the dialysis device 1 will be described. 3 to 5 are flowcharts showing the setting suggestion process of the dialysis machine 1 according to the first embodiment. 6 to 9 are diagrams showing examples of displays on the dialysis device 1 according to the first embodiment. 10 and 11 are diagrams showing an example of the smoothing process in the dialysis device 1 according to the first embodiment.

[0045] When a medical professional (a person who operates the dialysis machine 1 at a medical institution, hereinafter referred to as the operator) performs dialysis treatment on a patient, the medical professional first sets the type of dialysis treatment to be performed on the dialysis machine 1. The setting proposal process described below is a process related to the settings performed on the dialysis machine 1. In step S (hereinafter, "step S" will be simply referred to as "S") 11 in FIG. 3, the control unit 10 (patient designation receiving unit 11) receives a patient ID through an operation on the dialysis device 1 by an operator.

[0046] In S12, based on the received patient ID, the control unit 10 (past data extraction unit 13) extracts the past patient dialysis status data of the patient from the patient dialysis status data storage unit 32. Here, the control unit 10 extracts the past patient dialysis status data of the patient based on three patterns that are set in advance in the dialysis device 1 and indicate the range to be used as past data. In S13, the control unit 10 judges whether or not the predetermined patient dialysis status data based on the three patterns has been extracted. If the predetermined patient dialysis status data has been extracted (S13: YES), the control unit 10 moves the process to S14. On the other hand, if the predetermined patient dialysis status data has not been extracted (S13: NO), the control unit 10 moves the process to S19. Note that even if all of the above three patterns cannot be extracted, but at least one of them is extracted, the control unit 10 proceeds with the process with the answer being YES.

[0047] FIG. 6(A) shows an example of the operation display panel 36 displaying a screen 41 after a patient ID has been input. The screen 41 has a patient name 41a and a program designation area 41b. The patient name 41a displays the name of a patient identified by a patient ID. The program designation area 41b is an area for designating when executing a program that can be easily set. The operator checks the patient name 41a, confirms that the patient name is correct, and then selects the program designation area 41b. The control unit 10 then outputs a program selection screen (not shown). The operator selects the BV adjustment program from the screen. The BV adjustment program is a program that can set an alarm 1 line and control the water removal speed.

[0048] When the predetermined patient dialysis status data can be extracted in S12 of FIG. 3, the control unit 10 outputs the selection screen 42 shown in FIG. 6(B). The control unit 10 may output the selection screen 42 so as to be superimposed on the screen 41, or may output it instead of the screen 41. If the predetermined patient dialysis status data cannot be extracted in S12 of FIG. 3, the control unit 10 outputs a normal setting screen (not shown). In S19 of FIG. 3, the control unit 10 performs normal setting processing and then ends this processing. The normal setting processing is performed when the predetermined patient dialysis status data cannot be extracted, that is, when the patient's past dialysis status data has not been saved. Therefore, the operator needs to set it from the beginning, taking into account the patient's condition. Therefore, in this case, it is desirable for the operator to be a skilled medical professional who sets it from scratch as the operator.

[0049] Alternatively, if the operator is an inexperienced medical professional, the setting will not use the BV adjustment program that performs the minimum amount of water removal at an even speed. At that time, the control unit 10 measures the transition data of the circulating blood volume change rate that can be measured by a hematocrit measuring device, which is one of the various measuring devices 39, and expressed as %BV△, and stores it in the patient dialysis status data storage unit 32 as the current patient dialysis status data. In this way, from the next dialysis onwards, simple settings can be made based on the past patient dialysis status data of the patient stored in the patient dialysis status data storage unit 32.

[0050] In S14 of FIG. 3, the control unit 10 performs a condition setting process. Here, the condition setting process will be described based on example screens. The selection screen 42 illustrated in FIG. 6(B) is a selection screen for making simple settings, and has a simple setting button 42a. The button 42a is a button for enabling simple settings. The selection screen 42 also shows four icons with different circulating blood volume change rates (%). The proposed graphs corresponding to these four icons are preset.

[0051] When the operator selects the button 42a on the selection screen 42, the control unit 10 outputs a condition setting screen 43 shown in FIG. 6(C). The condition setting screen 43 is a screen for setting the target water removal volume and water removal time for the current dialysis treatment. When the operator sets the target water removal volume and water removal time on the condition setting screen 43 and selects the setting button 43a, the control unit 10 then outputs a condition setting screen 44 shown in Fig. 6(D). The condition setting screen 44 is a screen for setting the water removal rate and the maximum water removal rate in the current dialysis treatment. When the operator sets the water removal rate and the maximum water removal rate on the condition setting screen 44 and selects the setting button 44a, the control unit 10 determines that the condition setting process is completed and moves the process to S15 in FIG. 3.

[0052] In S15 of FIG. 3, the control unit 10 (threshold line setting unit 14) sets an alarm 1 line for each pattern, using the patient dialysis status data corresponding to each pattern extracted in the process of S12. In S16, the control unit 10 (proposal graph output unit 15) generates each of the proposal graphs including the set alarm 1 line, and outputs them to the operation display panel .

[0053] 7 shows an example of a screen 49 including a proposed graph and output to the operation display panel 36. When the control unit 10 accepts the selection of the button 44a on the condition setting screen 44 of FIG. Screen 49 has graph areas 49a to 49c and a selection area 49g. Graph areas 49a to 49c are areas for outputting proposed graphs. Graph area 49a is a proposed graph of pattern 1 generated by extracting patient dialysis status data from the previous dialysis treatment stored in the past (most recent). Graph area 49b is a proposed graph of pattern 2 generated by extracting patient dialysis status data from three dialysis treatments including the previous one stored in the past (most recent). Graph area 49c is a proposed graph of pattern 3 generated by extracting patient dialysis status data from a dialysis treatment stored one week ago.

[0054] Graph area 49b uses data from the past three times, so the number of lines presented as a graph is large. Further, each of the proposed graphs in the graph areas 49a to 49c includes the graphs 55a to 55c of the set alarm 1 line. If data for any pattern is insufficient, the graph cannot be presented, and so a message is output to the effect that there is no data in the relevant graph area. Selection area 49g is an area for selecting whether or not to make the alarm 1 line a correction line that has been smoothed. "With smoothing" is when smoothing is performed, and "without smoothing" is when smoothing is not performed. As an initial value, the screen 49 that is first output may be "without smoothing."

[0055] 4, the control unit 10 judges whether or not a designation regarding the presence or absence of smoothing has been received. If a designation regarding the presence or absence of smoothing has been received (S21: YES), the control unit 10 shifts the process to S22. On the other hand, if a designation regarding the presence or absence of smoothing has not been received (S21: NO), the control unit 10 shifts the process to S23. In S22, the control unit 10 (proposal graph output unit 15) outputs the processed proposal graphs corresponding to the designation to the operation display panel 36. After that, the control unit 10 shifts the process to S21.

[0056] For example, when an operation to change the selection area 49g in the screen 49 in Fig. 7 from "no smoothing" to "with smoothing" is received (S21 in Fig. 4: YES), the control unit 10 determines that a designation regarding the presence or absence of smoothing has been received. Then, the control unit 10 (smoothing processing unit 17) performs smoothing processing on the alarm 1 line to generate a correction line, and the control unit 10 (proposal graph output unit 15) outputs the generated correction line to the operation display panel 36 as the alarm 1 line (S22 in Fig. 4). 7, when an operation to change the selection area 49g from "with smoothing" to "without smoothing" is received (S21 in FIG. 4: YES), the control unit 10 also determines that a designation regarding the presence or absence of smoothing has been received. Then, the control unit 10 (proposal graph output unit 15) outputs the alarm 1 line set by the threshold line setting unit 14 to the operation display panel 36 (S22 in FIG. 4).

[0057] The smoothing process will now be described in more detail. Fig. 10(A) is a graph 60 showing an original waveform 60a when a fluid replacement step is included. Fig. 11(A) is a graph 70 showing an original waveform 70a when a fluid replacement step is not included. The horizontal axis of each graph is the time axis, and the vertical axis is the rate of change in circulating blood volume. The smoothing process is a process of performing various noise removal processes on the original waveforms 60a and 70a to generate a correction line. Fig. 10B is a graph 61 including a correction line 61b from which a specific frequency has been removed. Fig. 11B is a graph 71 including a correction line 71b from which a specific frequency has been removed. Both of the correction lines 61b and 71b form smoother lines compared to the original waveforms 60a and 70a, since the specific frequency has been removed.

[0058] Fig. 10C is a graph 62 including a correction line 62b obtained by taking a moving average. Fig. 11C is a graph 72 including a correction line 72b obtained by taking a moving average. The moving average is calculated, for example, in units of 30 minutes. Fig. 10(D) is a graph 63 including a correction line 63b represented by a cubic approximation curve, and Fig. 11(D) is a graph 73 including a correction line 73b represented by a cubic approximation curve.

[0059] Fig. 10(E) is a graph 64 including a correction line 64b traced with a lower limit, and Fig. 11(E) is a graph 74 including a correction line 74b traced with a lower limit. Fig. 10(F) is a graph 65 including a correction line 65b formed by tracing the lower limit and approximating a third-order curve, and Fig. 11(E) is a graph 75 including a correction line 75b formed by tracing the lower limit and approximating a third-order curve. The control unit 10 performs any one of the above-mentioned noise removal processes on the original waveform to perform smoothing and generate a correction line. The correction line can be a smooth line regardless of the noise removal process performed. If the original waveform contains an abnormal value, the control unit 10 may not select it as a target for smoothing. Also, for an original waveform that is short, the control unit 10 may complement a specific time (for example, up to 240 minutes) by maintaining the value of the circulating blood volume change rate at the end of dialysis of the original waveform.

[0060] In S23 of FIG. 4, the control unit 10 (proposed graph selection unit 18) determines whether or not a selection operation of a proposed graph has been accepted. For example, by selecting any of graph areas 49a to 49c on screen 49 of FIG. 7, the control unit 10 determines that a selection operation of a proposed graph has been accepted. If a selection operation of a proposed graph has been accepted (S23: YES), the control unit 10 transfers the process to S24. On the other hand, if a selection operation of a proposed graph has not been accepted (S23: NO), the control unit 10 transfers the process to S21. In S24, the control unit 10 outputs to the operation display panel 36 a proposed graph corresponding to the accepted selection.

[0061] FIG. 8(A) shows an example of a screen 45 that is output to the operation display panel 36 when the graph area 49b is selected in FIG. The screen 45 has a graph area 45a, adjustment buttons 45b to 45d, a setting button 45e, and a back button 45f.

[0062] The graph area 45a is an area for outputting a proposed graph. The graph area 45a includes graphs 55a to 55d and an area 55e. The right side of the graph area 45a shows how the data for the past three times is displayed. Graph 55a indicated by a solid line is a line showing the transition of the rate of change in circulating blood volume related to the most recent, previous, dialysis status data of the patient. Graph 55b shown by a dotted line is a line indicating the transition of the rate of change in circulating blood volume related to the patient's dialysis status data from the time before last. Graph 55c indicated by a dashed dotted line indicates the transition of the rate of change in circulating blood volume related to the patient's dialysis status data from three sessions prior. Graph 55d indicated by a thick dotted line is a candidate for the alarm 1 line to be used in the current dialysis treatment. The three lines included in the area 55e are the alarm 1 lines set during the previous, previous-but-previous, and third-previous dialysis treatments, respectively. The three alarm 1 lines each indicate which treatment they are from by the type of line.

[0063] Adjustment buttons 45b to 45d are buttons for adjusting the alarm 1 line. Adjustment button 45b is a button for moving graph 55d showing the alarm 1 line downward. Adjustment button 45c is a button for returning the moved alarm 1 line to its original position on graph 55d. Adjustment button 45d is a button for moving graph 55d showing the alarm 1 line upward. The operator uses adjustment buttons 45b and 45d to adjust the tightness (-) or looseness (+) of the alarm 1 line based on the patient's condition, such as past dialysis results (e.g., the patient's physical condition during the past dialysis) or the patient's condition in the upcoming dialysis session being better than in the past.

[0064] The set button 45e is a button for confirming the graph 55d set in the graph area 45a as an alarm 1 line. When the operator selects the set button 45e, the control unit 10 outputs a graph screen 46 shown in FIG. 8(B). The back button 45f is a button for returning to the previous screen 49.

[0065] The graph screen 46, which is displayed when the operator selects the setting button 45e, is a screen for confirming and saving a graph including the set alarm 1 line. The graph screen 46 has a graph display area 46a and buttons 46b to 46d. Graph display area 46a includes graph 56d and graphs 56f through 56h.

[0066] Graph 56d is the alarm 1 line set on screen 45 in FIG. 8(A). Graph 56f is the alarm 2 line, graph 56g is the alarm 3 line, and graph 56h is the alarm 4 line. Graph 56f is a line drawn at a position "-3" away from graph 56d, and graphs 56g and 56h are lines drawn at positions "-4" and "-7" away from the value of the final point of graph 56d, respectively. Here, the alarm 2 line is a line that is a reference for lowering the water removal speed. In addition, the alarm 3 line and the alarm 4 line are lines that set the water removal speed to a preset ratio (water removal change rate) with respect to the initial water removal speed. In addition, when the value falls below the alarm 2 line or the alarm 4 line, fluid replacement may be performed. In addition, the values ​​of "-3", "-4", and "-7" that are the change amount from the alarm 1 line are only examples, and are not limited to these values.

[0067] The button 46b is a button for saving the set conditions. When the button 46b is selected, the saved conditions are displayed as an icon 42-2x as shown in the selection screen 42-2 illustrated in FIG. 9(A) when setting the next dialysis treatment for the patient. Therefore, the settings can be made more easily when the patient undergoes the next dialysis treatment.

[0068] Button 46c is a button for changing the set conditions, and when selected, transitions to a change screen 47 shown in FIG. 9(B). Change screen 47 shown in FIG. 9(B) is a change screen for enabling fine adjustments to be made individually to the alarm 1 line to the alarm 4 line. The operator can fine-tune the alarm 1 line, etc., using change screen 47 and change screen 48 that is output by selecting the "Set" button on change screen 47. After fine adjustments, when the operator selects the "Set" button on change screen 48, control unit 10 outputs graph screen 46 shown in FIG. 8(B). The button 46d is a button for setting the set conditions only for the current dialysis treatment.

[0069] 5, the control unit 10 judges whether or not a change operation of the alarm 1 line has been received. If a change operation of the alarm 1 line has been received (S25: YES), the control unit 10 shifts the process to S26. On the other hand, if a change operation of the alarm 1 line has not been received (S25: NO), the control unit 10 shifts the process to S27. In S26, the control unit 10 (setting change receiving unit 25) changes the alarm 1 line in response to the change operation. Then, the control unit 10 outputs the changed alarm 1 line to the operation display panel 36.

[0070] For example, when the adjustment button 45b is selected on the screen 45 in Fig. 8(A) (S25 in Fig. 5: YES), the control unit 10 determines that an operation to change the alarm 1 line has been accepted. Then, the control unit 10 (setting change accepting unit 25) performs processing to move the graph 55d indicating the alarm 1 line downward, and the control unit 10 (proposal graph output unit 15) outputs the moved alarm 1 line to the operation display panel 36 (S26 in Fig. 5). 8(A) screen 45, for example, when the adjustment button 45d is selected (S25 in FIG. 5: YES), the control unit 10 also determines that an operation to change the alarm 1 line has been accepted. Then, the control unit 10 (setting change accepting unit 25) performs a process to move the graph 55d indicating the alarm 1 line upward, and the control unit 10 (proposal graph output unit 15) outputs the moved alarm 1 line to the operation display panel 36 (S26 in FIG. 5).

[0071] In S27 of FIG. 5, the control unit 10 judges whether or not a setting confirmation operation has been received. For example, when a selection operation of the setting button 45e is received on the screen 45 of FIG. 8(A), the control unit 10 judges that a setting confirmation operation has been received. When a setting confirmation operation has been received (S27: YES), the control unit 10 shifts the process to S28. On the other hand, when a setting confirmation operation has not been received (S27: NO), the control unit 10 shifts the process to S21 of FIG. 4. Here, when a setting confirmation operation has not been received, it refers to, for example, a case where a selection operation of the back button 45f is received on the screen 45 of FIG. 8(A).

[0072] In S28, the control unit 10 performs a process of confirming the settings. For example, when the button 46b is selected on the graph screen 46 of FIG. 8(B) that is output after the selection of the setting button 45e is accepted on the screen 45 of FIG. 8(A), the control unit 10 saves the setting values ​​obtained by the setting proposal process so that they can be used for the next setting and thereafter, and then saves them so that they can be used for the current dialysis process. When the button 46c is selected, the control unit 10 outputs a change screen 47 shown in FIG. 9(B) to the operation display panel 36, and fine-tunes the graph. When the button 46d is selected, the control unit 10 saves the setting values ​​so that they can be used for the current dialysis process. After that, the control unit 10 ends this process.

[0073] [Dialysis and data storage processing] Next, the dialysis process performed after the above setting proposal process and the subsequent processes will be described. FIG. 12 is a flowchart showing the dialysis and data storage process of the dialysis machine 1 according to the first embodiment. The operator inputs the patient's target water removal volume, water removal speed, etc., sets the setting value to "use" in the setting suggestion process described above, and then selects the dialysis start button (not shown) of the dialysis device 1. By doing so, in S51 of Fig. 12, the control unit 10 of the dialysis device 1 accepts the dialysis start operation.

[0074] In S52, the control unit 10 (dialysis processing unit 26) starts the dialysis process based on the saved settings (specifically, the target water removal amount, water removal time, water removal speed, maximum water removal speed, etc.) that can be used in the current dialysis process. The control unit 10 controls the water removal speed based on the rate of change in circulating blood volume measured by the various measuring devices 39 so that it follows the set alarm 1 line. In this way, the dialysis device 1 can perform dialysis that is gentle on the patient. In S53, the control unit 10 judges whether the dialysis treatment is completed. If the dialysis treatment is completed (S53: YES), the control unit 10 moves the process to S54. On the other hand, if the dialysis treatment is not completed (S53: NO), the control unit 10 remains in this process until the dialysis treatment is completed.

[0075] In S54, the control unit 10 (data storage processing unit 27) stores the patient dialysis status data obtained in the current dialysis process in the patient dialysis status data storage unit 32. Thereafter, the control unit 10 ends this process. In this way, the control unit 10 stores the patient dialysis status data obtained during each dialysis treatment, so that the stored patient dialysis status data can be used when setting up the next dialysis treatment.

[0076] As described above, the dialysis device 1 according to the first embodiment has the following advantages. In the first embodiment, when a patient to be dialysis is designated, multiple patterns of alarm 1 lines are set to control the change of the water removal speed based on the past patient dialysis status data of the patient to be dialysis extracted from the patient dialysis status data memory unit 32, and the multiple patterns of alarm 1 lines that have been set and each of the patient dialysis status data used to set the multiple patterns of alarm 1 lines are output to the operation display panel 36 for each pattern. As a result, when performing dialysis treatment, the alarm 1 line is set using the patient's dialysis status data, which is the past performance data of the patient, so the water removal speed for the patient can be changed based on the alarm 1 line. Since multiple patterns of alarm 1 lines are output for each pattern, the best mode for the current dialysis treatment can be selected from the multiple patterns of alarm 1 lines. In this way, it is possible to perform dialysis treatment that is gentle on the patient and prevents a drop in the patient's blood pressure. Also, if there is past dialysis status data for the patient, the alarm 1 line, which is one of the setting proposal data for the dialysis device 1 for that patient, is output. Therefore, even if the medical staff is not experienced, the alarm 1 line can be set, so that the setting can be easily performed.

[0077] Furthermore, in the first embodiment, the alarm 1 line, which is one of a plurality of patterns, is set based on the most recently stored previous patient dialysis status data as the patient's past patient dialysis status data. This makes it possible to conveniently set the alarm 1 line for any patient who has previously undergone dialysis treatment with the dialysis machine 1 at least once.

[0078] In the first embodiment, the alarm 1 line is set as one of a plurality of patterns based on the average value of the patient's dialysis status data including the most recently stored multiple times of the patient's dialysis status data, as the patient's past patient dialysis status data. Furthermore, in the first embodiment, the alarm 1 line is set as one of a plurality of patterns based on the patient's past patient dialysis status data having the same timing in the periodic dialysis cycle, as the patient's past patient dialysis status data. This allows the user to select the alarm line setting to be used for the current dialysis treatment from a variety of different patterns.

[0079] Also, in the first embodiment, a correction line is generated by performing a smoothing process on the set alarm 1 line, and the generated correction line is output as the alarm 1 line. Also, in the first embodiment, a correction line is generated in response to receiving a designation to perform smoothing. This allows the operator to set the alarm 1 line to a smooth line and to set the alarm 1 line according to the patient's condition. Also, by setting the alarm 1 line to a smooth line, the water removal speed can be changed smoothly. Then, the generation of the correction line from these alarm 1 lines is carried out for a plurality of patterns, so that the alarm 1 line can be set according to the state of the patient from various patterns.

[0080] In addition, in the first embodiment, by selecting one pattern from a plurality of patterns, the water removal speed is changed based on the relationship between the selected alarm 1 line and the patient's progress data during dialysis. This allows the operator to select the best alarm 1 line for the current dialysis treatment from the patient's past dialysis status data, and use it for the dialysis treatment.

[0081] In the first embodiment, when a change operation for the alarm 1 line is received, the water removal speed is changed based on the relationship between the changed alarm 1 line and the transition data of the patient during dialysis. This allows the operator to make fine adjustments to the alarm 1 line, which is set based on the patient's past dialysis status data, and to change it according to the patient's condition before dialysis treatment begins.

[0082] [Variations] In the above description, the screen 49 shown in Fig. 7 has a selection area 49g for selecting whether or not to make the alarm 1 line a correction line after smoothing processing, and the graph is switched according to the selection in the selection area 49g. However, the correction line after smoothing processing may be generated in advance and output as a list. FIG. 13 is a diagram showing another display example of the dialysis machine 1 according to the first embodiment. Screen 49-2 shown in Fig. 13 has graph areas 49a-2 to 49f-2. Graph areas 49a-2 to 49c-2 are the same as graph areas 49a to 49c in Fig. 7. Graph area 49d-2 outputs a corrected graph obtained by performing smoothing processing on the graph in graph area 49a-2. Similarly, graph area 49e-2 outputs a corrected graph for the graph in graph area 49b-2, and graph area 49f-2 outputs a corrected graph for the graph in graph area 49c-2. This makes it convenient to check both at a glance without having to switch between smoothing and not smoothing.

[0083] Second embodiment Next, a second embodiment of the present invention will be described. In the second embodiment, a proposed graph is generated by freely selecting past dialysis status data of a patient and using the selected data. In the following description, the same reference numerals or the same reference numerals with the same suffixes are used for parts that perform the same functions as those in the first embodiment, and duplicated descriptions are omitted as appropriate.

[0084] [Dialysis machine 201] FIG. 14 is a diagram showing functional blocks of a dialysis device 201 according to the second embodiment. As shown in FIG. 14, the dialysis machine 201 includes a control unit 210, a memory unit 230, an operation display panel 36, operation buttons 37, various pumps 38, and various measuring devices 39. Before describing the control unit 210, the storage unit 230 will be described. The storage unit 230 includes a program storage unit 231 and a patient dialysis status data storage unit 232 . The program storage unit 231 is a storage area for storing various programs, such as programs for executing various functions of the control unit 210, which will be described later.

[0085] The patient dialysis status data storage unit 232 is a storage area for storing patient dialysis status data indicating the dialysis status of the patient. Each item of the patient dialysis status data storage unit 232 is similar to that of the patient dialysis status data storage unit 32 of the first embodiment (FIG. 2). Here, the transition data of the patient dialysis status data includes time series data representing the transition of blood pressure and pulse rate as other transition data in addition to the transition data of blood parameters indicating the state of blood. Blood pressure may include systolic blood pressure, mean blood pressure, and diastolic blood pressure. In addition to the above transition data, the transition data may include time series data representing the transition of venous pressure, water removal amount, water removal speed, etc. The storage unit 230 also stores, for example, a minimum blood pressure value to be used as past data, which is preset for the dialysis device 201. The minimum blood pressure value is used to exclude past data in which a blood pressure below that value is measured.

[0086] Next, the control unit 210 will be described. The control unit 210 includes a patient designation receiving unit 11, a setting proposal processing unit 212, a setting change receiving unit 25, a dialysis processing unit 26, and a data storage processing unit 227. The setting proposal processing unit 212 includes a past data extraction unit 213, a past graph output unit 219 (past graph output means), a graph operation receiving unit 220 (data change receiving means, past graph receiving means), an exclusion designation receiving unit 221 (exclusion designation receiving means), a threshold line setting unit 214, a proposed graph output unit 215, a smoothing receiving unit 16, and a smoothing processing unit 17.

[0087] The past data extraction unit 213 extracts the patient dialysis status data of the patient stored in the patient dialysis status data storage unit 232 based on the patient ID accepted by the patient designation acceptance unit 11. The past data extraction unit 213 extracts, for example, from the patient dialysis status data storage unit 232, the patient dialysis status data of three consecutive dialysis treatments including the previous one that are stored in the past (most recent).

[0088] The past graph output unit 219 generates a past graph, which is a graph of the patient dialysis status data extracted by the past data extraction unit 213. Then, the past graph output unit 219 outputs the generated past graph to the operation display panel . In addition, when the past graph output unit 219 receives an operation related to changing the past graph from the graph operation receiving unit 220 described later, it outputs a past graph of the patient's dialysis status data corresponding to the operation to the operation display panel 36. Furthermore, when an exclusion designation is accepted by an exclusion designation accepting unit 221 described later, the past graph output unit 219 outputs a past graph of the patient's dialysis status data after the exclusion to the operation display panel .

[0089] The graph operation acceptance unit 220 accepts operations relating to changes to the past graphs output on the operation display panel . Furthermore, the graph operation acceptance unit 220 accepts the selection of one or more past graphs from among the past graphs output on the operation display panel . The exclusion designation receiving unit 221 receives an exclusion designation to exclude the use of the patient dialysis status data when the blood pressure of the patient dialysis status data is below the minimum blood pressure value stored in the memory unit 230 (indicating a specific condition).

[0090] The threshold line setting unit 214 sets an alarm 1 line (operation switching threshold line) for controlling to change the water removal speed based on the patient dialysis status data extracted by the past data extraction unit 213. The threshold line setting unit 214 may set the alarm 1 line based on the most recent patient dialysis status data output to the operation display panel 36 among the patient dialysis status data extracted by the past data extraction unit 213, or may set the alarm 1 line based on all patient dialysis status data output to the operation display panel 36. Furthermore, the threshold line setting section 214 may set an alarm 1 line based on the patient dialysis status data that is accepted by the graph operation accepting section 220 and that corresponds to the selected past graph. When the threshold line setting unit 214 sets the alarm 1 line based on patient dialysis status data corresponding to multiple past graphs, it sets the alarm 1 line based on the average value of the patient dialysis status data corresponding to multiple past graphs. In addition, the threshold line setting unit 214 may reset the value of a specific timing of the alarm 1 line set by the threshold line setting unit 214 (specifically, for example, 60 minutes, 120 minutes, 180 minutes, and 240 minutes from the start of dialysis) as the alarm 1 line.

[0091] The proposed graph output unit 215 generates a proposed graph including the alarm 1 line set by the threshold line setting unit 214 and a line indicating the patient dialysis status data used to set the alarm 1 line. Then, the proposed graph output unit 215 outputs the generated proposed graph to the operation display panel 36. Furthermore, when a correction line is generated by the smoothing processing unit 17, the proposed graph output unit 215 outputs the proposed graph to the operation display panel 36 with the generated correction line as the alarm 1 line. In addition, the proposed graph output unit 215 may reset the values ​​of specific timings (specifically, for example, 60 minutes, 120 minutes, 180 minutes, and 240 minutes from the start of dialysis) of the correction line generated by the smoothing processing unit 17 as the alarm 1 line.

[0092] The data storage processing unit 227 stores various data related to the patient resulting from the dialysis treatment by the dialysis processing unit 26 in the patient dialysis status data storage unit 232. The various data related to the patient includes, for example, time series data showing the trends in blood pressure and pulse rate as other trend data in addition to trend data of blood parameters. Blood pressure includes systolic blood pressure, mean blood pressure, and diastolic blood pressure. The data may also include weight and DW before dialysis treatment, and treatment details during dialysis treatment.

[0093] Next, as the processing in the dialysis device 201, the processing when the dialysis device 201 is used to perform dialysis treatment on a patient will be described. [Settings proposal process] 15 to 18 are flowcharts showing the setting suggestion process of the dialysis machine 201 according to the second embodiment. 19 and 21 are diagrams showing examples of displays on the dialysis device 201 according to the second embodiment. FIG. 20 is a diagram showing an example of an operation of the dialysis device 201 according to the second embodiment.

[0094] The process of S211 in FIG. 15 is similar to the process of S11 in the first embodiment (FIG. 3). In S212, the control unit 210 (past data extraction unit 213) of the dialysis device 201 extracts, based on the received patient ID, past patient dialysis status data of the patient from the patient dialysis status data storage unit 232. Here, the control unit 210 extracts, for example, from the patient dialysis status data storage unit 232, patient dialysis status data for three consecutive dialysis treatments including the previous one that are stored in the past (most recent). In S213, the control unit 210 judges whether or not the patient dialysis status data has been extracted. If the patient dialysis status data for even one session has been extracted (S213: YES), the control unit 210 shifts the process to S214. On the other hand, if the patient dialysis status data has not been extracted (S213: NO), the control unit 210 shifts the process to S219.

[0095] In S214, the control unit 210 (past graph output unit 219) generates a past graph which is a graph of the patient's dialysis status data extracted in the process of S212. The process of S215 is similar to the process of S14 in the first embodiment (FIG. 3). In S216, the control unit 210 (threshold line setting unit 214) sets an alarm 1 line based on, for example, the most recent patient dialysis status data among the patient dialysis status data extracted in the process of S212. In S217, the control unit 210 (proposal graph output unit 215) generates a proposal graph including the alarm 1 line set in the process of S216. Then, the control unit 210 (past graph output unit 219, proposal graph output unit 215) outputs the past graph generated in the process of S214 and the generated proposal graph to the operation display panel 36.

[0096] 19(A) shows an example of a screen 250 including a past graph and a proposed graph, which is output to the operation display panel 36. When the control unit 210 receives the selection of the button 44a on the condition setting screen 44 of FIG. The screen 250 includes a past graph area 250a, a proposed graph area 250b, a selection area 250c, data change buttons 250d and 250e, an exclusion designation area 250f, and a setting button 250g. The past graph area 250a is an area for outputting multiple past graphs (up to three in this example). In this example, the past graph area 250a outputs past graphs in order from the most recent dialysis treatment date to the oldest.

[0097] Here, the output contents of the past graph will be described with reference to FIG. FIG. 19B shows graphs 251 a to 251 f to be output as one past graph 251 . Graph 251a indicated by a solid line is a line indicating the transition of the rate of change in circulating blood volume related to the patient's dialysis status data. Graph 251b shown as a solid line below graph 251a is the alarm 1 line set during dialysis treatment. Graphs 251c to 251e are lines showing the trends in systolic blood pressure, mean blood pressure, and diastolic blood pressure, respectively. Graph 251f is a line showing the transition of pulse rate.

[0098] Proposed graph area 250b in FIG. 19(A) is an area for outputting a proposed graph. The selection area 250c is an area for selecting whether or not to make the alarm 1 line a correction line that has been smoothed. "With smoothing" is when smoothing is performed, and "without smoothing" is when smoothing is not performed. As an initial value, the screen 250 that is first output may be "without smoothing." The data change buttons 250d and 250e are for changing the past graph to be output. Selecting the data change button 250d outputs a past graph of a more recent dialysis treatment date. Selecting the data change button 250e outputs a past graph of an older dialysis treatment date.

[0099] The exclusion designation area 250f is an area for designating exclusion to exclude use of patient dialysis status data when the blood pressure of the patient dialysis status data is below the diastolic blood pressure value stored in the memory unit 230. When the exclusion designation area 250f is checked, the control unit 210 outputs a past graph, excluding the patient dialysis status data whose blood pressure is below the diastolic blood pressure value. The setting button 250g is for proceeding with the processing based on the proposed graph output in the proposed graph area 250b.

[0100] In S221 of Fig. 16, the control unit 210 (exclusion designation receiving unit 221) determines whether or not exclusion designation has been selected. For example, when the exclusion designation area 250f of Fig. 19(A) is checked, the control unit 210 determines that exclusion designation has been selected. If exclusion designation has been selected (S221: YES), the control unit 210 transfers the process to S222. On the other hand, if exclusion designation has not been selected (S221: NO), the control unit 210 transfers the process to S223. In S222, the control unit 210 (past graph output unit 219) generates a past graph, excluding the dialysis status data of the patient whose blood pressure is below the diastolic blood pressure value, and outputs the graph to the operation display panel .

[0101] In S223, the control unit 210 (graph operation receiving unit 220) determines whether or not an operation to change the past graph has been received. For example, when either of the data change buttons 250d and 250e in FIG. 19(A) is selected, the control unit 210 determines that an operation to change the past graph has been received. If an operation to change the past graph has been received (S223: YES), the control unit 210 transfers the process to S224. On the other hand, if an operation to change the past graph has not been received (S223: NO), the control unit 210 transfers the process to S225. In S224, the control unit 210 (past graph output unit 219) extracts the patient dialysis status data corresponding to the operation of changing the past graph from the patient dialysis status data storage unit 232, generates a past graph, and outputs it to the operation display panel .

[0102] In S225, the control unit 210 (graph operation receiving unit 220) determines whether or not a selection operation of a past graph has been received. For example, as shown in Fig. 20, the operator presses down the finger F at position Fa in the past graph area 250a, drags it in the lower right direction, and then drops it so as to surround a plurality of past graphs, thereby forming an enclosing area 250h. With such an operation, the control unit 210 receives the selection of two past graphs in the enclosing area 250h. If a selection operation of a past graph has been received (S225: YES), the control unit 210 shifts the process to S226. On the other hand, if a selection operation of a past graph has not been received (S225: NO), the control unit 210 shifts the process to S227 in FIG.

[0103] In S226, the control unit 210 (threshold line setting unit 214, proposed graph output unit 215) generates and outputs a proposed graph corresponding to the received selection. More specifically, the control unit 210 (threshold line setting unit 214) sets the alarm 1 line based on the patient dialysis status data corresponding to the past graph received in the processing of S225. Then, the control unit 210 (proposed graph output unit 215) generates a proposed graph including the set alarm 1 line and a line indicating the patient dialysis status data used to set the alarm 1 line, and outputs it to the operation display panel 36. For example, when enclosing region 250h is formed in FIG. 20, control unit 210 updates the proposed graph to be output to proposed graph region 250b to one that uses data corresponding to the past graph included in enclosing region 250h, and outputs the updated proposed graph.

[0104] The process of S227 in Fig. 17 is similar to the process of S21 in the first embodiment (Fig. 4). If NO is selected in S227, the control unit 210 moves the process to S229. In S228, the control unit 210 (proposal graph output unit 215) outputs the processed proposal graph corresponding to the designation to the operation display panel 36. More specifically, the control unit 210 updates the proposal graph in the proposal graph area 250b of the screen 250 shown in Fig. 19(A) to the processed proposal graph. Thereafter, the control unit 210 shifts the process to S227.

[0105] In S229, the control unit 210 judges whether or not a selection operation of the setting button has been accepted. More specifically, when the setting button 250g is selected on the screen 250 shown in Fig. 19(A), the control unit 210 judges that a selection operation of the setting button has been accepted. When a selection operation of the setting button has been accepted (S229: YES), the control unit 210 shifts the process to S230. On the other hand, when a selection operation of the setting button has not been accepted (S229: NO), the control unit 210 shifts the process to S221 in Fig. 16. In S230, the control unit 210 outputs the proposed graph being output on the screen 250 (see FIG. 19(A)) to a screen 245 shown in FIG. 21 as a separate screen.

[0106] A screen 245 shown in FIG. 21 has a graph area 245a, adjustment buttons 245b to 245d, a setting button 245e, and a back button 245f. Graph region 245a includes graph 255a, graph 255d, and graphs 255f through 255h. Graph 255a shown by a solid line is a line indicating the transition of the rate of change in circulating blood volume related to the patient's dialysis status data on the past dialysis day specified on the previous screen 250 (see FIG. 19(A)). Graph 255d shown by a thick dotted line is a candidate for the alarm 1 line to be used in the current dialysis treatment. Graph 255f is the alarm 1 line that was set during dialysis treatment on a past dialysis day. Graph 255g and graph 255h are examples of the alarm 1 line after adjustment using adjustment button 245b and adjustment button 245d.

[0107] 18 are similar to the processes from S25 to S28 in the first embodiment (FIG. 5). If the result of the process in S233 is NO, the control unit 210 shifts the process to S221 in FIG.

[0108] The dialysis process performed after the above setting proposal process and the subsequent processes are similar to those in the first embodiment (FIG. 12). 12, the control unit 210 (data saving processing unit 227) stores the patient dialysis status data obtained in the current dialysis process in the patient dialysis status data storage unit 232. At this time, the control unit 210 stores in the patient dialysis status data storage unit 232 the transition data of the patient dialysis status data, including time series data showing the transitions of blood pressure and pulse rate as other transition data, in addition to the transition data of blood parameters showing the state of the blood.

[0109] As described above, the dialysis device 201 according to the second embodiment has the following advantages. In the second embodiment, when the designation of a dialysis target patient is accepted, a past graph of the patient dialysis status data of the dialysis target patient for multiple past sessions extracted from the patient dialysis status data storage unit 232 is output to the operation display panel 36. In addition, an alarm 1 line for controlling the change of the water removal speed is set based on at least one or more of the patient dialysis status data for multiple past sessions, and a proposed graph including the set alarm 1 line and the patient dialysis status data used to set the alarm 1 line is output to the operation display panel 36. As a result, when performing dialysis treatment, the alarm 1 line is set using the patient's dialysis status data, which is the past performance data of the patient, so the water removal speed for the patient can be changed based on the alarm 1 line. Since a past graph is output, it is possible to clearly show that the alarm 1 line has been set from the past graph.

[0110] In addition, in the second embodiment, when an operation related to changing a past graph is accepted, a past graph of the changed patient dialysis status data, including the patient dialysis status data corresponding to the operation extracted from the patient dialysis status data memory unit 232 in response to the accepted operation, is output to the operation display panel 36. This allows a past graph of the patient's past dialysis status data to be output in response to an operation.

[0111] In the second embodiment, when the selection of one or more past graphs is accepted from the past graphs output on the operation display panel 36, the alarm 1 line is set based on the patient dialysis status data corresponding to the accepted one or more past graphs. When multiple past graphs are selected, the alarm 1 line is set based on the average value of the patient dialysis status data. As a result, the alarm 1 line is set using the selected past graph, so that the alarm 1 line can be appropriately set using one or more arbitrarily selected pieces of patient dialysis status data.

[0112] In addition, in the second embodiment, the patient dialysis status data memory unit 232 stores patient dialysis status data, which further includes data showing the trends in the patient's blood pressure and pulse rate during at least one dialysis treatment, in association with the patient, and the patient dialysis status data in the past graph output to the operation display panel 36 includes the trends in the rate of change in circulating blood volume and the trends in blood pressure and pulse rate. Therefore, not only the rate of change in circulating blood volume but also the trends in blood pressure and pulse rate can be confirmed from the graph.

[0113] In addition, in the second embodiment, when the blood pressure of the patient dialysis status data is below the minimum blood pressure value stored in the memory unit 230, if an exclusion specification is received to exclude the use of that patient dialysis status data, the patient dialysis status data indicating that condition is excluded and a past graph is output to the operation display panel 36. Therefore, it is possible to exclude in advance patient dialysis status data that meets conditions that are to be excluded from the setting of the alarm 1 line.

[0114] [Variations] In the above description, the example was described in which lines indicating the rate of change in circulating blood volume, blood pressure, and pulse rate related to the patient dialysis status data are output in the past graph 251 illustrated in Fig. 19(B), and an alarm 1 line set during the dialysis treatment is output. However, the lines to be output are not limited to these. FIG. 22 is a diagram showing an example of display of another past graph 252 in the dialysis device 201 according to the second embodiment. The past graph 252 shows a plurality of graphs 252a, 252c, and 252e, as well as graphs 252h1 to 252h4. Graph 252a is a line showing the transition of the rate of change in circulating blood volume related to the patient's dialysis status data. Graph 252c is a line showing the progress of systolic blood pressure. Graph 252e is a line showing the change in minimum blood pressure. Graphs 252h1 to 252h4 represent alarm 1 line to alarm 4 line set during dialysis treatment. Even when output using such a past graph 252, the progress during past dialysis treatment can be clearly shown.

[0115] The present invention is not limited to the embodiments, and includes modifications and improvements within the scope of the present invention that can achieve the object of the present invention. The above-described embodiments and the modified forms described below can be used in appropriate combinations, but detailed description thereof will be omitted.

[0116] (Variations) In each embodiment, the patient dialysis status data of each patient stored in the memory unit of the dialysis device is used. Although no particular description is given about the patient dialysis status data of each patient to be used, data for which dialysis treatment was stopped midway may be excluded. Alternatively, if dialysis treatment was stopped midway, the data may not be stored in the memory unit of the dialysis device.

[0117] In each embodiment, the patient dialysis status data of each patient is stored in the storage unit of the dialysis device, but the present invention is not limited to this. For example, the patient dialysis status data of each patient may be stored in a storage medium such as a USB that is detachable from the dialysis device, so that the patient dialysis status data of the patient can be extracted from the storage medium even when a different dialysis device is used. Alternatively, the patient dialysis status data of each patient may be stored in a data storage device such as a database that is communicatively connected to the dialysis device, so that the patient dialysis status data of the patient can be extracted by accessing the data storage device from the dialysis device.

[0118] In each embodiment, the dialysis device includes a setting suggestion device that performs a process on the dialysis device, but the present invention is not limited to this. The setting suggestion device may be a device separate from the dialysis device, and in this case, it is sufficient that the dialysis device is able to acquire the setting contents of the setting suggestion device.
