DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

FIG. 1 is a schematic diagram showing the main configuration of the extracorporeal circulation apparatus 1 of the present invention.
The extracorporeal circulation apparatus 1 shown in FIG. 1 is an apparatus that extracorporeally circulates the blood of the patient P shown in FIG. 1. This “extracorporeal circulation” includes “extracorporeal circulation operation” and “auxiliary circulation operation”.
The “extracorporeal circulation operation” is performed by the extracorporeal circulation device 1 when blood cannot be exchanged in the patient P because the blood does not circulate in the heart of the patient (subject) P to which the extracorporeal circulation device 1 is applied. A blood circulation operation and a gas exchange operation (oxygen addition and / or carbon dioxide removal) for the blood are performed.
The “auxiliary circulation operation” is a case where blood circulates in the heart of a patient (subject) P to which the extracorporeal circulation apparatus 1 is applied and gas exchange can be performed in the lungs of the patient P. Is also to assist blood circulation. Some devices have a function of performing a gas exchange operation on blood.

  By the way, in the extracorporeal circulation apparatus 1 shown in FIG. 1 according to the present embodiment, it is used, for example, when performing cardiac surgery on the patient P or in a subsequent hospital room or the like. Specifically, for example, the centrifugal pump 3 which is a pump part of the extracorporeal circulation apparatus 1 is operated, blood is removed from the vein (vena cava) of the patient P, and the blood is pumped into the blood by the artificial lung 2, for example, the artificial lung 2. After the oxygen exchange of the blood by performing this gas exchange, “extra-artificial blood circulation” is performed in which the blood is returned to the artery (aorta) of the patient P again. That is, the extracorporeal circulation device 1 is a device that performs substitution of the heart and the lung, which is a cardiopulmonary assist function for the patient P.

The extracorporeal circulation apparatus 1 has the following configuration. That is, as shown in FIG. 1, the extracorporeal circulation device 1 has a “circulation circuit 1R” for circulating blood, and the circulation circuit 1R is an “artificial lung 2”, a “centrifugal pump 3”, and a motor unit. , “Drive motor 4”, “venous side catheter (blood removal side catheter) 5”, “arterial side catheter (blood feeding side catheter) 6”, and an extracorporeal circulation management device, for example, a controller 100. . The centrifugal pump 3 is also called a blood pump, and pumps other than the centrifugal type can be used.
That is, the centrifugal pump 3 plays an important role for circulating blood, and this centrifugal pump 3 is operated by receiving a command (SG) from the controller 100 and being driven by the drive motor 4. It has become.
Thus, the drive motor 4 is an extremely important component in the extracorporeal circulation device 1.

1 is inserted from the femoral vein, and the tip of the venous catheter 5 is placed in the right atrium. An artery side catheter (blood supply side catheter) 6 is inserted from the femoral artery. The venous catheter 5 is connected to the centrifugal pump 3 using a blood removal tube 11. A blood removal tube (also referred to as “blood removal line”) 11 is a conduit for sending blood.
As described above, when the drive motor 4 is operated according to the command SG of the controller 100 and the centrifugal pump 3 is operated, the centrifugal pump 3 removes blood from the blood removal tube 11 and passed through the artificial lung 2. It is configured to return to the patient P via the blood supply tube 12 (also referred to as “liquid supply line”).

The artificial lung 2 is disposed between the centrifugal pump 3 and the blood supply tube 12. The oxygenator 2 performs a gas exchange operation (oxygen addition and / or carbon dioxide removal) on the blood. The oxygenator 2 is, for example, a membrane oxygenator, and a hollow fiber membrane oxygenator is particularly preferably used. The blood supply tube 12 is a conduit connecting the artificial lung 2 and the artery side catheter 6.
For the blood removal tube 11 and the blood supply tube 12, for example, a synthetic resin conduit having high transparency such as vinyl chloride resin or silicone rubber can be used.
In the blood removal tube 11, blood flows in the V direction, and in the blood supply tube 12, blood flows in the W direction.

Further, the extracorporeal circulation apparatus 1 has a “blood flow sensor 14” in the blood removal tube 11. This blood flow sensor 14 is configured to detect the value of the flow rate of blood flowing from the patient P through the blood removal tube 11.
Further, a “pressure sensor 15” is disposed on the patient P side of the blood supply tube 12.
This “pressure sensor 15” is configured to detect the pressure value of the blood in the blood supply tube 12. That is, the pressure sensor 15 is a sensor for measuring the pressure of blood passing through the pipe line, and is a sensor for detecting an abnormal blood pressure.
Blood pressure abnormalities are often caused by kinking of the tube of the circulation line 1R, clogging of the artificial lung 2, clogging of the centrifugal pump 3, etc., and this pressure abnormality may cause hemolysis (destruction of red blood cells). . In addition, the tube may come off due to an increase in pressure, and blood leakage or the like may occur.
Therefore, the extracorporeal circulation device 1 has a pressure sensor 15 to measure the pressure of blood in the pipeline, and when there is a circulation abnormality information such as a pressure abnormality, a “warning” or An alarm device (not shown) for issuing an “alarm” is provided in the controller 100.

The blood flow sensor 14 is a sensor that measures a flow value of blood passing through the pipeline, and is a sensor for detecting an abnormality in the flow value.
An abnormality in the flow rate value is caused by a kink in the tube of the circulation line 1R, a decrease in the rotation speed of the drive motor 4 and the centrifugal pump 3, an increase in pressure loss, and the like, causing poor circulation of blood in the circulation line 1R. This may cause hypoxia or the like in the patient.
Therefore, the extracorporeal circulation device 1 has a blood flow sensor 14, measures the blood flow rate in the conduit, and when there is an abnormality in the flow rate, an alarm device for issuing an “alarm” under certain conditions ( (Not shown) is provided in the controller 100.
For example, an ultrasonic flow sensor or the like is used as the blood flow sensor 14.

Further, when an abnormal flow rate or the like occurs in the blood in the conduit, in order to prevent the blood from being sent to the patient P in such an abnormal state, the pressure sensor 15 of the blood supply tube 12 in FIG. The controller 100 can be urgently closed using forceps.
In addition, as shown in FIG. 1, the controller 100 has a “display (touch panel) 102 with an input function”.
The display 102 with an input function has a touch panel structure that displays various types of information and allows the operator to input various types of information by touching the screen.

As shown in FIG. 1, the extracorporeal circulation device 1 has a management device 200 that is communicably connected to the controller 100 via a LAN or the like. As will be described later, the management apparatus 200 is configured to exhibit a function of acquiring and managing information on the drive motor 4 and the like from the controller 100.
The controller 100 and the management apparatus 200 may be connected not only by wire but also wirelessly, and information on the drive motor 4 and the like of the controller 100 is stored in a recording medium such as a USB, and thereafter from the storage medium The configuration may be such that information is input to the management apparatus 200.

  The controller 100, the management device 200, and the like of the extracorporeal circulation apparatus 1 shown in FIG. 1 have a computer. The computer includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like (not shown). These are connected via a bus.

  FIG. 2 is a schematic block diagram showing the main configuration of the controller 100 of FIG. As illustrated in FIG. 2, the controller 100 includes a “controller control unit 101”, and the controller control unit 101 controls the “controller side communication device 103” for communicating with the management device 200. The controller control unit 101 is configured to control the touch panel 102.

The controller control unit 101 is also configured to control a “timer 104” and a “controller body 105” that generate time information. The controller body 105 is a device that controls blood circulation and the like of the extracorporeal circulation device 1.
Further, the controller control unit 101 also controls the “controller-side first various information storage unit 110” and the “controller-side second various information storage unit 120” shown in FIG.

As illustrated in FIG. 5, the management apparatus 200 includes a “management apparatus control unit 201”. The management apparatus control unit 201 stores “management apparatus side communication apparatus 202” for communicating with the controller 100 and various types of information. The “management device side display 203” to be displayed and the “management device side input device 204” for inputting various information are controlled.

8 to 10 are schematic flowcharts showing main operation examples and the like of the extracorporeal circulation device 1 of FIG. Hereinafter, it explains along these flowcharts, and also explains the configuration of FIG. 1 to FIG. 7 and the like. Further, in this embodiment, the drive motor 4 used in the extracorporeal circulation device 1 shown in FIG. An example in which it is determined whether or not the drive motor 4 has been deteriorated to a necessary level by acquiring the operation time and the like, and when such replacement is necessary, that fact is displayed on the touch panel 102 of the controller 100. Will be described below.

First, in step ST (hereinafter referred to as “ST”) 1 in FIG. 8, the controller 100 in FIG. 1 determines whether or not the drive motor 4 is properly connected as shown in FIG.
That is, when the extracorporeal circulation device 1 is installed for the patient P, a medical worker such as a hospital combines the parts such as the controller 100, the artificial lung 2, the drive motor 4, and the extracorporeal circulation for the patient P. The device 1 is assembled. For this reason, in ST1, it is determined whether or not the assembly of the extracorporeal patient apparatus 1 has been executed.

If it is determined in ST1 that the drive motor 4 is connected, the process proceeds to ST2. In ST 2, the “serial number acquisition unit (program) 111” of the controller 100 in FIG. 3 operates to acquire the serial number that is the identification number of the drive motor 4, the date of manufacture, and the limit operating time of the drive motor 4. Then, the drive motor 4 is specified and stored in the “serial number storage unit 112” in FIG.
The limit operating time is a limit operating time unique to each drive motor 4, and the limit of the operating time of each drive motor 4 can be accurately grasped by this information.
Thus, the controller 100 can specify the serial number of the drive motor 4 currently connected to the controller 100. In addition, the date of manufacture of the drive motor 4 can be specified.

Next, the process proceeds to ST3. In ST3, the controller 100 determines whether or not the connected drive motor 4 is in an operating state.
Here, the operation content of the drive motor 4 will be described. As described above, the drive motor 4 has an operation for operating the centrifugal pump 3, that is, a “normal operation” in which the blood of the patient P is circulated extracorporeally and performs an auxiliary operation of the cardiopulmonary function. In addition to the normal operation, the drive motor 4 introduces and fills a “priming solution (for example, physiological saline)” into a blood circuit (pipe) such as the blood removal tube 11 or the liquid feeding tube 12. By repeating the rotation and stop of the drive motor 4, a “special operation” such as auto-priming, in which processing (priming) for removing foreign substances and air in the blood circuit is automatically performed.

The special operation such as auto-priming repeats the rotation and stop of the drive motor 4, so that the load on the drive motor 4 is larger than the normal operation and the drive motor 4 is easily deteriorated.
Therefore, “normal operation” and “special operation” are examples of information on the degree of burden on the drive motor 4. Here, a special operation is performed when the load on the motor due to generated heat or the like is larger than a predetermined operation, while a normal operation is performed when the load on the motor is equal or small. In other words, the operation of the motor that is larger than the predetermined load coefficient is a special operation, and the operation of the motor that is equal to or smaller than the predetermined load coefficient is a normal operation.

  By the way, when it is determined in ST3 that the drive motor 4 is in an operating state, the process proceeds to ST4. In ST4, measurement of the operation time of the drive motor 4 is started using the timing device 104 of FIG. 2, and the operation instruction content from the controller 100 to the drive motor 4 (for example, “normal operation” or “special operation”, etc.) ) Is stored in the “operation history information storage unit 113” of FIG.

Next, the process proceeds to ST5. In ST5, the controller 100 determines whether or not the operation of the drive motor 4 has been completed.
If it is determined in ST5 that the operation of the drive motor 4 has been completed, the process proceeds to ST6. In ST6, the “operation content determination unit (program) 114” of FIG. 3 operates and refers to the operation history information storage unit 113 to determine whether or not the operation is “normal operation”.

In ST6, when the operation of the drive motor 4 is normal operation, the process proceeds to ST7, and the operation time of the time measuring device 104 is stored as “normal operation time information” in the “normal operation time information storage unit 115” in FIG. Let
On the other hand, when it is determined in ST6 that the operation is not a normal operation, the process proceeds to ST8. In ST8, the operation time of the timing device 104 is stored as “special operation time information” in the “special operation time information storage unit 121” in FIG.

  In the present embodiment, the actual operating time of the drive motor 4 is measured using the timing device 104. However, in the present invention, the present invention is not limited to this. The “operation” time or the “special operation” time may be stored.

  Next, the process proceeds to ST9. In ST9, the “drive motor total operation time calculation unit (program) 122” of FIG. 4 operates and refers to the “normal operation time information storage unit 115” and the “special operation time information storage unit 121”, and FIG. The drive motor total operation time calculation information (drive motor total operation time calculation formula) in the “drive motor total operation time calculation information storage unit 123” is referred to.

This drive operation time calculation information (drive operation time calculation formula) is, for example, total operation time (Tt) = normal operation time (Tn) + (special operation time (Ts) × assumed burden coefficient (α, for example, 2.5 ).
That is, in the special operation such as auto-priming, the load on the drive motor 4 is larger than the normal operation. Therefore, even if the operation is performed for the same time, the calculation is performed with a 2.5 times increase in load in the special operation. . In other words, the special operation is calculated so as to contribute more to the deterioration of the drive motor 4.
Therefore, in ST9, the controller 100 substitutes the normal operation time information of the “normal operation time information storage unit 115” and the special operation time information of the “special operation time information storage unit 121” into the drive motor total operation time calculation formula. Then, the drive motor total operating time is calculated.

The “total drive motor operating time” calculated in this way is an example of the motor deterioration information.
In the present embodiment, the deterioration information of the drive motor 4 is divided into operation types such as normal operation and special operation that have different loads depending on the operation, and the operation time is determined.
Therefore, for example, the special operation with a heavy load on the drive motor 4 is calculated by converting, for example, 2.5 times the time of the normal operation, so that more accurate deterioration information can be generated.
Further, in the present embodiment, deterioration information is generated based on time information, so the degree of deterioration can be easily and clearly determined.
Furthermore, in the present embodiment, the drive motor total operating time is generated by the controller 100 close to the drive motor 4, so that highly accurate deterioration information can be generated.

In the present embodiment, the above-described auto-priming operation time is used as an example of the “special operation time”. However, the present invention is not limited to this, and the target of the “special operation time” is In addition, a special operation time based on “a coefficient β in which the heat generated by the operation of the drive motor 4 affects the drive motor 4”, a special operation time based on the “coefficient γ depending on the temperature of the use environment of the drive motor 4”, and the like are also included.
In the case of “coefficient β in which the heat generated by the operation of the drive motor 4 affects the drive motor 4”, the generated heat is obtained by calculating with the operation time of the drive motor and the coefficient β. ].
The “coefficient γ depending on the temperature of the operating environment of the drive motor 4” is the operating time of the drive motor 4, the temperature data of the operating environment at that time, and the coefficient γ. Time ".

  In ST9, the drive motor total operation time calculated as described above is stored in the “drive motor total operation time information storage unit 124” in FIG. 4. At this time, refer to the serial number storage unit 112 in FIG. The drive motor total operation time is stored in association with the serial number, the date of manufacture, and the limit operation time of the drive motor.

  Next, the process proceeds to ST10. In ST10, the controller 100 receives the serial number, date of manufacture, and drive motor total operating time information with a limit operating time in the drive motor total operating time information storage unit 124 via the controller side communication device 103, as shown in FIG. It transmits to the management apparatus 200.

Next, the process proceeds to ST11. In ST11, the management device 200 receives the serial motor, the manufacturing date, and the drive motor total operation time information with the limit operation time via the management device side communication device 202.
Then, the “use history presence / absence determination unit (program) 211” in FIG. 6 operates, and the “serial number of the drive motor total operating time information with the serial number etc.” received is the “use history information storage unit in FIG. Whether or not it is stored in “212” is determined.

In the use history information storage unit 212, for each serial number, “drive motor total operation accumulated time information”, “manufacturing date”, and “limit operation” that are the accumulated time of the drive motor total operation time of each drive motor 4 are stored. "Time" is stored.
As described above, the management device 200 stores, for example, the serial number, manufacturing date, limit operating time, and drive motor total operation accumulated time information of each drive motor 4 used in the hospital. The apparatus 200 can manage all the drive motors 4 in a unified and centralized manner. Therefore, it is possible to accurately determine the deterioration information of each drive motor 4 based on the same standard.
The drive motor total operation accumulated time information is also an example of deterioration information.

In ST11, when “the serial number of the received drive motor total operating time information with the serial number etc.” is stored in the use history information storage unit 212, the process proceeds to ST12.
In ST12, the “drive motor total operation time accumulated time generation unit (program) 213” operates, and the “drive motor total operation accumulated time” stored in “the serial number” stores the “drive motor total operation”. By adding “time”, a new drive motor total operation accumulated time is generated and stored as “drive motor total operation accumulated time” in the “use history information storage unit 212” of FIG.
Therefore, the management apparatus 200 can manage the latest drive motor total operation accumulated time information of the drive motor 4.

On the other hand, in ST11, when “the serial number of the received drive motor total operating time information with the serial number etc.” is not stored in the use history information storage unit 212, the process proceeds to ST13.
In ST13, the “serial number registration processing unit (program) 214” of FIG. 6 operates to register “the serial number” and set the “drive motor total operation time” of the serial number to “the drive motor total operation accumulated time”. Is stored in the use history information storage unit 212 of FIG. Further, the “manufacturing date” and “limit operating time” of the drive motor 4 are also stored in the use history information storage unit 212.

Therefore, for example, a new drive motor 4 that has not been managed by the management apparatus 200 until now can be automatically managed.
Thus, the management apparatus 200 can manage the current state of all the drive motors 4 in the hospital in the latest state.

Next, the process proceeds to ST14. In ST14, the “warning availability determination processing unit (program) 221” in FIG. 7 operates and refers to the “use history information storage unit 212” in FIG. 6 and the “warning information storage unit 215” in FIG.
The warning information storage unit 215 stores the service life information and service life information of the drive motor 4.
Therefore, it is possible to determine whether or not the drive motor total operation accumulated time stored in the “use history information storage unit 212” exceeds the durable operation time.

It can also be determined from the date of manufacture stored in the “use history information storage unit 212” whether or not the drive motor 4 has exceeded its useful life.
Further, from the limit operating time of the drive motor 4 stored in the “use history information storage unit 212”, the total drive motor accumulated operation time stored in the “use history information storage unit 212” is calculated as the limit operation time. It can also be determined whether or not it exceeds.
Therefore, in ST14, it is determined whether or not there is a drive motor 4 (serial number) that has exceeded the “lifetime” and / or “lifetime” and / or “marginal time”.

  If it is determined in ST14 that there is a drive motor 4 (serial number) that has exceeded the “service life” and / or “service life” and / or “limit operation time”, the process proceeds to ST15. In ST15, the serial number of the drive motor 4 that has exceeded the service life and / or service life and / or “limit operating time”, and the service life and / or service life and / or “limit operation time” exceeded “Fact” is stored in the “warning target serial number and warning fact storage unit 222” of FIG.

  Next, the process proceeds to ST16. In ST16, the “warning notification unit (program) 223” of FIG. 7 operates, refers to the “warning target serial number and warning fact storage unit 222”, and uses the drive motor 4 of the corresponding serial number. A warning (year of use and / or drive motor total operating time and / or limit operating time, replacement notice) is sent to

  Next, the process proceeds to ST17. In ST17, the controller 100 displays a warning (year of use and / or drive motor total operation accumulated time and / or limit operation time, replacement notice) on the touch panel 102.

Therefore, clinical engineers, nurses, doctors, and the like who have visually recognized this warning can accurately grasp the replacement time of the drive motor 4 that is an important part of the extracorporeal circulation apparatus 1, and the drive motor 4 can be broken down. Occurrence of troubles related to human life based on this can be prevented.
In this embodiment, since all the plurality of drive motors 4 in the hospital are centrally managed by the management apparatus 200, judgments such as the replacement timing of the drive motors 4 can be made in a unified manner. As a result, the accuracy of judgment such as replacement time is improved.

  By the way, the present invention is not limited to the above-described embodiment.
