To suppress only a blood pump from operating while a syringe pump does not operate in a medical device.SOLUTION: In a medical device 1, a controller 70 operates a blood pump 10, and interlocks a syringe pump 20 with the blood pump 10. A screen 80 displays a first screen 81 which indicates whether or not the controller 70 is in a state of interlocking the syringe pump 20 with the blood pump 10, or a second screen 82 which does not indicate whether or not the controller 70 interlocks the syringe pump 20 with the blood pump 10. When a screen transition input part 91 receives an input when the screen 80 displays the first screen 81, and the first screen 81 indicates an interlocking stop state of the syringe pump 20, the controller 70 transits a screen to be displayed by the screen 80 from the first screen 81 to the second screen 82, and starts interlocking of the syringe pump 20.SELECTED DRAWING: Figure 8

Description

[Technical Field]

[0001] The present disclosure relates to medical devices. [Background technology]

[0002] Japanese Patent Laid-Open Publication No. 2004-313370 (Patent Document 1) discloses a hemodialysis machine including a display and setting system as a medical device. Blood from the patient's artery is supplied to the blood flow path of the hemodialysis machine via a blood pump consisting of a metering pump installed in the blood circuit. To prevent blood clotting, the hemodialysis machine is capable of injecting minute amounts of an anticoagulant such as heparin into the blood circuit using a syringe pump as needed. The machine is also equipped with an operation panel, which includes a screen that displays the details of each process in the hemodialysis machine and allows settings to be changed.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-313370 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to simplify the operation of conventional medical devices, it has been considered to link a syringe pump with a blood pump. If the syringe pump is linked with the blood pump, the syringe pump will also be operated when the operator operates the blood pump. This simplifies the operation of the medical device.

[0005] On the other hand, when replacing a syringe attached to a syringe pump, an operator needs to stop the link between the syringe pump and the blood pump. However, if the screen displayed on the screen of the medical device changes while the link is stopped, the operator may have difficulty recognizing from the screen that the link between the syringe pump and the blood pump has stopped. This may lead to a situation where, when the operator operates the blood pump, the operator believes that the syringe pump is linked to the blood pump, when in fact the syringe pump is not operating.

[0006] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a medical device that can prevent the syringe pump from operating without the blood pump operating. [Means for solving the problem]

[0007] A medical device according to the present disclosure includes a blood pump, a syringe pump, a controller, a screen, and at least one screen transition input unit. The blood pump is configured to pump blood in a blood line. The syringe pump is configured to pump a medicinal solution in a syringe to the blood line. The controller operates the blood pump and links the syringe pump to the blood pump. The screen displays a first screen indicating whether the controller is linking the syringe pump to the blood pump, or a second screen indicating whether the controller is linking the syringe pump to the blood pump. The screen transition input unit accepts input for transitioning the screen displayed on the screen from the first screen to the second screen. When the screen displays the first screen and the first screen indicates that the syringe pump is not linked, upon receiving the input, the controller transitions the screen displayed on the screen from the first screen to the second screen and starts linking the syringe pump.

[0008] In a medical device according to an embodiment of the present disclosure, the screen is a touch screen that accepts input to a controller. The first screen includes an interlock start object image that accepts input to start interlocking of the syringe pump at least when the interlocking of the syringe pump is stopped. The second screen does not include the interlock start object image.

[0009] In a medical device according to an embodiment of the present disclosure, the screen is a touch screen that receives input to a controller. The first screen includes an interlock stop object image that receives input to stop interlocking of the syringe pump when the syringe pump is interlocked with the blood pump. The second screen does not include the interlock stop object image.

[0010] A medical device according to one embodiment of the present disclosure further includes an interlock start input unit, an interlock stop input unit, and an alarm unit. The interlock start input unit accepts input for starting interlocking of the syringe pump when the syringe pump is not interlocked with the blood pump. The interlock stop input unit accepts input for stopping interlocking of the syringe pump when the syringe pump is interlocked with the blood pump. The alarm unit notifies information related to interlocking of the syringe pump. After the interlock stop input unit accepts input, causing the controller to stop interlocking of the syringe pump, if a predetermined time has elapsed while the interlock start input unit is not accepting input and the screen transition input unit is not accepting input, the controller activates the alarm unit. [Effects of the Invention]

[0011] According to the present disclosure, even if a screen transition occurs that makes it difficult to recognize from the screen that the syringe pump has stopped interlocking, the syringe pump interlocking is automatically resumed without the operator having to perform a separate operation to resume interlocking. This prevents the syringe pump from operating without the blood pump operating. [Brief explanation of the drawings]

[0013] Hereinafter, the configuration of a medical device according to an embodiment of the present disclosure will be described with reference to the drawings. In the following description of the embodiment, the same or corresponding parts in the drawings will be denoted by the same reference numerals, and the description thereof will not be repeated.

[0014] Fig. 1 is a perspective view showing the appearance of a medical device according to an embodiment of the present disclosure. Fig. 2 is a circuit diagram showing the configuration of a blood circuit of a medical device according to an embodiment of the present disclosure. Fig. 3 is a hardware configuration diagram of a medical device according to an embodiment of the present disclosure.

[0015] As shown in FIGS. 1 to 3, a medical device 1 according to an embodiment of the present disclosure includes a blood pump 10, a syringe pump 20, an alarm unit 60, a controller 70, and a screen 80.

[0016] 2, the medical device 1 is specifically a blood purification device, more specifically a blood purification device used for continuous renal replacement therapy (CRRT). However, the medical device 1 may be a blood purification device used for any of continuous hemodiafiltration (CHDF), continuous hemofiltration (CHF), continuous hemodialysis (CHD), and slow continuous ultrafiltration (SCUF).

[0017] The blood pump 10 is configured to be able to pump blood in a blood pipeline 11. The medical device 1 further includes a blood purifier 12, and the blood pump 10 causes the blood in the blood pipeline 11 to flow into the blood purifier 12. The blood pump 10 is typically a rotary pump.

[0018] Syringe pump 20 is configured to be able to deliver the medicinal liquid in syringe 21 to blood pipeline 11. Examples of the medicinal liquid in syringe 21 include anticoagulants such as heparin and nafamostat. Syringe pump 20 can deliver the medicinal liquid at a substantially constant flow rate into blood pipeline 11 by a fixed-rate injection operation. Syringe pump 20 can also deliver the medicinal liquid to blood pipeline 11 by a bolus injection operation, which injects a desired volume of the medicinal liquid in a relatively short period of time.

[0019] The medical device 1 further includes one or more other pumps 30. The medical device 1 includes, as the pumps 30, a dialysate pump 31, a drainage pump 32, and a substitution fluid pump 33. The dialysate pump 31 delivers dialysate to the blood purifier 12. The drainage pump 32 delivers drainage fluid discharged from the blood purifier 12. The substitution fluid pump 33 delivers substitution fluid (replacement fluid) to the blood circuit of the medical device 1. The type of pump 30 is not particularly limited, and may be a peristaltic pump or a roller pump.

[0020] The medical device 1 further includes one or more pressure gauges 40. Examples of the pressure gauges 40 include a pressure gauge that measures outlet pressure, a pressure gauge that measures inlet pressure, a pressure gauge that measures return pressure, and a pressure gauge that measures filtration pressure. The medical device 1 may further include other pressure gauges in addition to those described above.

[0021] 1 and 3, the alarm unit 60 notifies information related to the interlocking of the syringe pump 20. The alarm unit 60 notifies the operator of the medical device 1 of predetermined information by flashing. Specifically, the alarm unit 60 is an alarm lamp, but the alarm unit 60 may also be an alarm light or alarm message information displayed on the screen 80. The alarm unit 60 may also notify information related to the interlocking of the syringe pump 20 by emitting a sound.

[0022] 3, the controller 70 is specifically a control board, and includes a processor 71 and a memory 72. The controller 70 controls the overall operation of the medical device 1. Specifically, the processor 71 controls the operation of the medical device 1 by executing various programs stored in the memory 72.

[0023] Specifically, the controller 70 operates (starts and stops) the blood pump 10 and links the syringe pump 20 to the blood pump 10. The state in which the syringe pump 20 is linked to the blood pump 10 refers to a state in which the controller 70 controls the operation of the syringe pump 20 when it is controlling the operation of the blood pump 10, and does not control the operation of the syringe pump 20 when it is not controlling the operation of the blood pump 10. In other words, the state in which the syringe pump 20 is not linked to the blood pump 10 refers to a state in which the controller 70 does not control the operation of the syringe pump 20, regardless of whether the controller 70 is controlling the operation of the blood pump 10.

[0024] The controller 70 also controls the operation of the other pumps 30 and the alarm unit 60. The controller 70 also acquires, from one or more pressure gauges 40, the values ​​of the pressures measured by the pressure gauges 40.

[0025] Fig. 4 is a diagram showing an example of a first screen displayed on a screen of a medical device according to an embodiment of the present disclosure. Fig. 5 is a diagram showing another example of a first screen displayed on a screen of a medical device according to an embodiment of the present disclosure. Fig. 6 is a diagram showing an example of a second screen displayed on a screen of a medical device according to an embodiment of the present disclosure.

[0026] As shown in Figures 3 to 6, the screen 80 displays a first screen 81 indicating whether the controller 70 is linking the syringe pump 20 with the blood pump 10, or a second screen 82 indicating whether the controller 70 is linking the syringe pump 20 with the blood pump 10.

[0027] First, the first screen 81 will be described. In Fig. 4, the screen 80 displays the first screen 81, and the first screen 81 indicates that the controller 70 has linked the syringe pump 20 with the blood pump 10 (hereinafter, this may be simply referred to as "the syringe pump 20 is in a linked state"). In Fig. 5, the screen 80 displays the first screen 81, and the first screen 81 indicates that the controller 70 has not linked the syringe pump 20 with the blood pump 10 (hereinafter, this may be simply referred to as "the syringe pump 20 is in a non-linked state"). The first screen 81 has a link information display section 83 that indicates whether the syringe pump 20 is in a linked state.

[0028] The screen 80 has a first display area 80A, a second display area 80B, and a third display area 80C, which are arranged at different positions. In the first screen 81, the interlocking information display unit 83 is located in the first display area 80A. In the first screen 81, the flow rate setting value and the bolus injection rate setting value of the syringe pump 20 set by the controller 70 are also displayed in the first display area 80A. In addition, the second display area 80B mainly displays the measurement values ​​of the various pressure gauges 40 acquired by the controller 70. The third display area 80C mainly displays the operation setting values ​​of each pump 30 set by the controller 70. In addition, in the first screen 81, the flow rate setting value of the blood pump 10 set by the controller 70 is displayed outside these display areas. The arrangement, number, and size of each display area on the screen 80 are not particularly limited.

[0029] Next, the second screen 82 will be described. In the example shown in FIG. 6, the first display area 80A of the second screen 82 displays trend graphs of the measured values ​​of the various pressure gauges 40. The information displayed in the first display area 80A of the second screen 82 is completely different from that displayed on the first screen 81. Therefore, the second screen 82 does not have an interlocking information display section 83 that indicates whether the controller 70 has the syringe pump 20 in an interlocked state or an interlock-stop state. Furthermore, the second screen 82 does not display the flow rate setting value and bolus injection volume setting value of the syringe pump 20 set by the controller 70. Note that information other than the trend graph may be displayed in the first display area 80A of the second screen 82. In the example shown in FIG. 6, the information displayed in the second display area 80B and the third display area 80C of the second screen 82 is the same as that displayed on the first screen 81 shown in FIGS. 4 and 5.

[0030] 3, the screen 80 is specifically a touch screen that receives input to the controller 70. More specifically, the screen 80 is a resistive touch screen. The screen 80 has a display 88 and a touch panel 89 that is placed over the display 88. The function of the screen 80 as a touch screen will be described later.

[0031] 7 is a functional block diagram of a medical device according to an embodiment of the present disclosure. As shown in FIG. 7, the medical device 1 according to an embodiment of the present disclosure further includes at least one screen transition input unit 91, a linkage start input unit 92, and a linkage stop input unit 93.

[0032] The screen transition input unit 91 accepts input for transitioning the screen displayed on the screen 80 from a first screen 81 to a second screen 82. There may be multiple screen transition input units 91. In this case, the screen 80 is capable of displaying multiple types of second screens 82. The information displayed by each of the multiple second screens 82 may be partially different from one another. When any of the multiple screen transition input units 91 accepts input, the controller 70 transitions the first screen 81 to any one of the multiple second screens 82 that corresponds to the screen transition input unit 91.

[0033] The interlock start input unit 92 accepts an input for starting interlocking of the syringe pump 20 when the syringe pump 20 is not interlocked with the blood pump 10. The interlock stop input unit 93 accepts an input for stopping interlocking of the syringe pump 20 when the syringe pump 20 is interlocked with the blood pump 10.

[0034] The medical device 1 also includes the screen transition input unit 91 as a first screen transition input unit, and a second screen transition input unit 94. The second screen transition input unit 94 receives an input for transitioning the screen displayed on the screen 80 from the second screen 82 to the first screen 81.

[0035] The hardware that realizes each of the above input units is not particularly limited, and may be a physical button, a physical pin, a physical switch, a keyboard, or a mouse. In this embodiment, each input unit is an object image displayed on the (touch) screen 80.

[0036] 4, the first screen 81 includes an interlocking stop object image 811 that receives input for stopping the interlocking of the syringe pump 20 at least when the syringe pump 20 is in an interlocked state with the blood pump 10. In the present embodiment, the first screen 81 includes the interlocking stop object image 811 only when the syringe pump 20 is in an interlocked state. The interlocking stop object image 811 corresponds to the interlocking stop input unit 93. The interlocking stop object image 811 is located in the first display area 80A.

[0037] First screen 81 also includes an object image that accepts input of a set value for the amount of medicinal liquid to be injected by syringe pump 20, an object image that accepts input of a set value for the amount of injection when bolus injection is performed by syringe pump 20, and a decision object image for confirming that syringe pump 20 will be operated at these set values. First screen 81 also includes an object image that accepts input to start bolus injection by syringe pump 20, and an object image that accepts input to operate syringe pump 20 at fast forward. These object images are also located in first display area 80A on first screen 81.

[0038] Furthermore, first screen 81 further includes a cancel object image 813 for canceling changes to the interlocking settings and operation settings for syringe pump 20 that were set on first screen 81. Cancel object image 813 is located in first display area 80A. When cancel object image 813 accepts an input, first screen 81 transitions to one of second screens 82, and controller 70 maintains the various setting values ​​for control of syringe pump 20 that have been stored without changing them.

[0039] 5, the first screen 81 includes an interlock start object image 812 that receives input for starting interlocking of the syringe pump 20 at least when the interlocking state of the syringe pump 20 is shown. In the present embodiment, the first screen 81 includes the interlock start object image 812 only when the syringe pump 20 is in the interlocking stopped state. The interlock start object image 812 corresponds to the interlock start input unit 92. The interlock start object image 812 is located in the first display area 80A. The interlock start object image 812 is displayed in the same position as the interlock stop object image 811 on the screen 80.

[0040] 6, second screen 82 does not include interlock start object image 812 or interlock stop object image 811. Furthermore, as described above, the display content in first display area 80A on second screen 82 is completely different from that in first display area 80A on first screen 81. Therefore, second screen 82 does not include an object image for accepting input of a set value for the amount of medicinal liquid to be injected by syringe pump 20, an object image for accepting input of a set value for the amount of injection when bolus injection is performed by syringe pump 20, or a confirmation object image for confirming that syringe pump 20 is to be operated at these set values. Furthermore, second screen 82 does not include an object image for accepting input for starting bolus injection by syringe pump 20, or an object image for accepting input for operating syringe pump 20 at fast forward.

[0041] As shown in FIGS. 4 to 6 , each of the first screen 81 and the second screen 82 includes a plurality of changed object images 850. Each of the plurality of changed object images 850 accepts an input for at least changing the content of the display information in the first display area 80A. The plurality of changed object images 850 includes a plurality of first changed object images 851 and a second changed object image 852. When the screen 80 displays the first screen 81, if any of the plurality of first changed object images 851 accepts an input, the first screen 81 transitions to one of the plurality of second screens 82. At this time, only the display content of the first display area 80A may be changed, or the display of the entire screen displayed on the screen 80 may be changed. When the screen 80 displays the second screen 82, if the second changed object image 852 accepts an input, the second screen 82 transitions to the first screen 81. At this time, only the display content of first display area 80A may be changed, or the display of the entire screen displayed on screen 80 may be changed. Second changed object image 852 shows set flow rate information of syringe pump 20 and size setting information of syringe 21 attached to syringe pump 20.

[0042] Therefore, the cancel object image 813 and the plurality of first changed object images 851 each correspond to the screen transition input unit 91. The second changed object image 852 corresponds to the second screen transition input unit 94.

[0043] Hereinafter, a process executed in a medical device 1 according to an embodiment of the present disclosure, after the interlocking of the syringe pump 20 is stopped while the interlocking is in progress, until the interlocking is started again, will be described. FIG. 8 is a flow diagram for explaining the flow of the process executed in a medical device according to an embodiment of the present disclosure. The series of processes shown in FIG. 8 are started when the syringe pump 20 is in the interlocking state in the medical device 1. That is, the process is started when the screen 80 displays a first screen 81 as shown in the example of FIG. 4.

[0044] First, in step S11, controller 70 determines whether or not the interlocking stop input unit 93 has received an input. If interlocking stop input unit 93 has not received an input (NO in step S11), this process is repeated.

[0045] When controller 70 acquires information indicating that interlock stop input unit 93 has accepted an input (YES in step S11), in step S12, controller 70 stops the interlocking of syringe pump 20. Then, in step S13, controller 70 displays the interlocking stopped state of syringe pump 20 in interlock information display unit 83 of first display area 80A on first screen 81 (see FIG. 5). At the same time, controller 70 hides interlock stop object image 811 on first screen 81 and displays interlock start object image 812 (see FIGS. 4 and 5).

[0046] Next, in step S14, controller 70 determines whether or not interlocking start input unit 92 has received an input. When controller 70 acquires information indicating that interlocking start input unit 92 has received an input (YES in step S14), controller 70 restarts interlocking of syringe pump 20 in step S15.

[0047] Here, if interlock start input unit 92 has not received an input (NO in step S14), in step S21, controller 70 determines whether or not screen transition input unit 91 has received an input. If screen transition input unit 91 receives an input (YES in step S21), controller 70 transitions the screen displayed on screen 80 from first screen 81 to second screen 82, and starts interlocking of syringe pump 20 in step S15.

[0048] Furthermore, if the interlock start input unit 92 has not received an input (NO in step S14) and the screen transition input unit 91 has not received an input either (NO in step S21), the controller 70 determines whether a predetermined time has elapsed since the interlocking of the syringe pump 20 was stopped in step S31. The predetermined time may be set in advance in the controller 70 or may be changeable by receiving an input from the operator. The predetermined time is set, for example, to a length of time that allows replacement of the syringe 21. The predetermined time is, for example, two minutes. If the predetermined time has not elapsed since the controller 70 stopped the interlocking of the syringe pump 20 (NO in step S31), the process returns to step S14.

[0049] If it is determined that the predetermined time has elapsed (YES in step S31), the controller 70 activates the alarm unit 60 in step S32.

[0050] In a state in which alarm unit 60 is activated due to the lapse of a predetermined time, controller 70 determines in step S41 whether or not interlock start input unit 92 has received an input. When controller 70 acquires information indicating that interlock start input unit 92 has received an input (YES in step S41), controller 70 restarts interlocking of syringe pump 20 in step S15.

[0051] Furthermore, when alarm unit 60 is activated due to the passage of a predetermined time, if interlock start input unit 92 has not received an input (NO in step S41), controller 70 determines in step S51 whether screen transition input unit 91 has received an input. If screen transition input unit 91 has not received an input (NO in step S51), the process returns to step S41. When controller 70 acquires information indicating that screen transition input unit 91 has received an input (YES in step S51), controller 70 transitions the screen displayed on screen 80 from first screen 81 to second screen 82, and in step S15, controller 70 starts interlocking of syringe pump 20 again.

[0052] In the medical device 1 according to an embodiment of the present disclosure, after the syringe pump 20 is stopped in an interlocked state, the above-described processing is executed to start the interlock again.

[0053] As described above, in the medical device 1 according to this embodiment, when the screen 80 displays the first screen 81 and the first screen 81 indicates that the syringe pump 20 is in a stopped state of interlocking, if the screen transition input unit 91 receives an input, the controller 70 transitions the screen displayed on the screen 80 from the first screen 81 to the second screen 82 and starts interlocking the syringe pump 20.

[0054] If the display on screen 80 transitions to second screen 82, which does not show the interlocking status of syringe pump 20, it becomes difficult for the operator to realize that interlocking of syringe pump 20 should be resumed. However, with the above configuration, even if the screen transition makes it difficult for the operator of medical device 1 to recognize from screen 80 that interlocking of syringe pump 20 has stopped, interlocking of syringe pump 20 is automatically resumed without the operator having to perform a separate operation for resuming interlocking (for example, an input operation into interlock start input unit 92). This makes it possible to prevent only the blood pump 10 from operating without the syringe pump 20 operating.

[0055] Furthermore, in the medical device 1 according to this embodiment, the screen 80 is a touch screen that receives input to the controller 70. The first screen 81 includes an interlock start object image 812 that receives input to start interlocking of the syringe pump 20, at least when the interlocking stop state of the syringe pump 20 is shown. The second screen 82 does not include the interlock start object image 812.

[0056] With the above configuration, the interlock start object image 812 is displayed on the first screen 81 along with the interlocking status of the syringe pump 20, allowing the operator to easily operate the interlocking of the syringe pump 20. On the other hand, when the display on the screen 80 related to the interlocking of the syringe pump 20 transitions to the second screen 82, the interlock start object image 812 is no longer displayed, making it difficult for the operator to be aware of the interlocking operation of the syringe pump 20. However, in this embodiment, the interlocking of the syringe pump 20 starts upon transition from the first screen 81 to the second screen 82. Therefore, even if it becomes difficult to recognize from the screen 80 that the interlocking of the syringe pump 20 has stopped due to the screen transition, the interlocking of the syringe pump 20 is automatically resumed without the operator having to perform a separate operation to resume the interlocking (for example, an input operation to the interlock start input unit 92). This makes it possible to prevent only the blood pump 10 from operating without the syringe pump 20 operating.

[0057] Furthermore, in the medical device 1 according to this embodiment, the screen 80 is a touch screen that receives input to the controller 70. The first screen 81 includes an interlock stop object image 811 that receives input for stopping the interlocking of the syringe pump 20 at least when the syringe pump 20 is in an interlocked state with the blood pump 10. The second screen 82 does not include the interlock stop object image 811.

[0058] With the above configuration, the interlock stop object image 811 is displayed on the first screen 81 along with the interlocking status of the syringe pump 20, allowing the operator to easily operate the interlocking of the syringe pump 20. On the other hand, when the display of the operation screen related to the interlocking of the syringe pump 20 transitions to the second screen 82, which does not include the interlock start object, the interlock stop object image 811 is no longer displayed, making it difficult for the operator to be aware of the interlocking operation of the syringe pump 20. However, in this embodiment, the interlocking of the syringe pump 20 starts upon transition from the first screen 81 to the second screen 82. Therefore, even if it becomes difficult to recognize from the screen 80 that the interlocking of the syringe pump 20 has been stopped due to the screen transition, the interlocking of the syringe pump 20 is automatically resumed without the operator having to perform a separate operation to resume the interlocking (for example, an input operation to the interlock start input unit 92). This makes it possible to prevent the blood pump 10 from operating alone without the syringe pump 20 operating.

[0059] Furthermore, in the medical device 1 according to this embodiment, after the interlock stop input unit 93 accepts input and the controller 70 stops the interlocking of the syringe pump 20, if a predetermined time has elapsed while the interlock start input unit 92 is not accepting input and the screen transition input unit 91 is not accepting input, the controller 70 activates the alarm unit 60.

[0060] The above configuration can prompt the operator to perform an operation to resume interlocking of the syringe pump 20. Consequently, it can be prevented that only the blood pump 10 operates without the syringe pump 20 operating.

[0061] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive.
