[First Embodiment]
<1. Overall configuration of extracorporeal circulation device>
1A of FIG. 1 is a diagram illustrating an example of the overall configuration of the extracorporeal circulation device 100 according to the first embodiment of the present invention.

The extracorporeal circulation device 100 is used not only for extracorporeal circulation such as cardiac surgery but also for auxiliary circulation procedures such as PCPS (percutaneous cardiopulmonary support) and ECMO (extracorporeal membrane oxygenation), and performs cardiopulmonary assist operations (extracorporeal circulation operation, priming operation). Do. The extracorporeal circulation apparatus 100 has a blood extracorporeal circuit (hereinafter referred to as a circulation circuit) indicated by an arrow in the figure. In the extracorporeal circulation apparatus 100, after performing the priming operation, the blood of the subject 130 is circulated extracorporeally using this circulation circuit.

Here, the priming operation refers to an operation of removing the bubbles in the circuit by circulating the priming solution in the circulation circuit in a state where the circulation circuit is sufficiently filled with the priming solution (for example, physiological saline).

The extracorporeal circulation device 100 includes a controller 110 that functions as a control device, a drive motor 111, a centrifugal pump 112, an oxygenator 113, an oxygen supply source 117, a catheter (venous side) 119, and a catheter (arterial side) 120. A bubble sensor 114, a flow sensor 115, a blood filter 116, a branch line 118, a clamp 122, and a pressure sensor 123. These components are connected by a flexible tube or the like, and the lumen of the tube forms a flow path for blood or priming liquid.

The catheter (arterial side) 120 pumps blood toward the body of the subject 130, and the catheter (venous side) 119 performs blood removal from the body of the subject 130.

The centrifugal pump 112 is also called a centrifugal artificial heart, drives a rotating body provided inside, applies pressure to the blood, and circulates the blood in the circulation circuit. The drive motor 111 gives a rotational driving force to the rotating body of the centrifugal pump 112. The pressure in the circulation circuit before being pressurized by the centrifugal pump 112 is detected by the pressure sensor 123.

The artificial lung 113 performs blood circulation and blood gas exchange (oxygen addition, carbon dioxide removal, etc.). The oxygen supply source 117 is realized by, for example, an oxygen cylinder and supplies oxygen to be added to blood. The oxygen supplied from the oxygen supply source 117 is used at the time of gas exchange by the artificial lung 113.

The bubble sensor 114 detects bubbles contained in the priming liquid (or blood) flowing in the circulation circuit during the priming operation (or during the extracorporeal circulation operation) by a predetermined detection method (ultrasonic wave, light, etc.). The blood filter 116 filters blood or removes bubbles in the blood. The flow sensor 115 includes, for example, a built-in ultrasonic transceiver, and detects the flow rate of the priming liquid (or blood) in the circulation circuit.

The clamp 122 is a member for closing the tube so as to forcibly stop the blood supply toward the body of the subject 130 during the extracorporeal circulation operation. The clamp 122 performs blood feeding based on a manual mode in which a medical worker performs an occlusion operation by inputting an occlusion instruction on the controller 110 and output signals from the bubble sensor 114, the flow sensor 115, the pressure sensor 123, and the like. When it is determined that an abnormality to stop immediately has occurred, it is possible to operate in the automatic control mode in which the closing operation is automatically performed.

The branch line 118 switches the flow path of the circulation circuit. Specifically, when the blood of the subject 130 is circulated extracorporeally, a circulation circuit passing through the body of the subject 130 is constructed as shown in 1A of FIG. Circulate. During the priming operation, as shown in 1B of FIG. 1, the circuit of the circulation circuit to the inside of the body of the subject 130 is blocked by the branch line 118 (in other words, the circulation circuit that passes only the outside of the subject 130 (in other words, the subject A circulation circuit that does not pass through the body of the person 130 is constructed, and the circulation circuit is filled with the priming liquid (without passing through the body of the subject) to circulate the priming liquid. On the circulation circuit, one or a plurality of bubble discharge ports (not shown) for discharging bubbles are provided. By circulating a plurality of priming liquids in the circulation circuit, the bubbles in the circulation circuit are circulated. It will be discharged from the bubble discharge port.

The controller 110 comprehensively controls the extracorporeal circulation operation and the priming operation in the extracorporeal circulation device 100. In the controller 110, for example, the centrifugal motor 112 is driven by controlling the drive motor 111, or the gas exchange operation is performed by controlling the artificial lung 113. Further, the bubble sensor 114 is controlled to acquire an output signal from the bubble sensor 114, and the flow rate sensor 115 and the pressure sensor 123 are controlled to acquire a flow rate value and a pressure value. Further, when an abnormality that requires blood supply to be stopped is detected based on output signals from the bubble sensor 114, the flow sensor 115, and the pressure sensor 123, the clamp 122 is closed.

Next, the flow of processing when performing cardiopulmonary assist operation (extracorporeal circulation operation, priming operation) using the extracorporeal circulation device 100 shown in FIGS. 1A and 1B will be briefly described.

When the cardiopulmonary assist operation is started, the controller 110 controls the execution of the priming operation. During the priming operation, a circulation circuit that does not pass through the body of the subject 130 is constructed by the branch line 118 as shown in 1B of FIG. At this time, the priming liquid supply source 121 is connected to the branch line 118, and the priming liquid is supplied from the priming liquid supply source 121 into the circulation circuit. As a result, the circulation circuit is filled with the priming liquid.

Then, the centrifugal pump 112 is driven by the control of the controller 110, and the priming liquid circulates in the circulation circuit a plurality of times. Bubbles in the circulation circuit are discharged from the bubble discharge port or the like with this circulation. At this time, bubbles in the circulation circuit are detected by the bubble sensor 114, and the controller 110 determines whether or not there are bubbles contained in the circulation circuit and the size of the bubbles based on the detection result of the bubble sensor 114. .

Here, in the controller 110, when the result of the determination satisfies a predetermined standard, the priming operation is terminated. At the end of this, the controller 110 notifies the user that the priming operation has ended using a display (not shown), a speaker (not shown), or the like. The user who receives the notification of the end of the priming operation switches the branch line 118 and constructs a circulation circuit that passes through the body of the subject 130 as shown in 1A of FIG. Thereby, the blood of the subject 130 is circulated extracorporeally.

When the extracorporeal circulation operation starts, blood that has been removed from the catheter (vein side) 119 enters the oxygenator 113 via the centrifugal pump 112. In the artificial lung 113, as described above, gas exchange, that is, processing such as oxygen addition and carbon dioxide removal is performed. Thereafter, the filtered blood is sent from the catheter (arterial side) 120 into the body of the subject 130 through the blood filter 116 and the like. This process from blood removal to blood transfer is repeated, and the blood of the subject 130 is circulated extracorporeally.

The above is an explanation of an example of the overall configuration of the extracorporeal circulation device 100 according to the present embodiment and the flow of cardiopulmonary assist operation. Note that the configuration of the extracorporeal circulation device 100 shown in FIGS. 1A and 1B is merely an example, and the configuration may be changed as appropriate.

<2. Functional configuration of controller>
Next, an example of a functional configuration of the controller 110 illustrated in FIG. 1 will be described with reference to FIG.

The controller 110 includes a display unit 203, an operation unit 202, a storage unit 201, an I / F unit 206, a timer unit 204, a communication unit 207, and a control unit (computer) 205 as functional configurations. .

The display unit 203 is realized by, for example, a display such as a monitor (including an output unit that outputs an alarm sound), and displays various types of information to the user. The operation unit 202 is realized by various buttons, for example, and inputs an instruction from a medical worker. Part or all of the display unit 203 and the operation unit 202 may be realized as a touch panel with an audio speaker, for example.

The storage unit 201 is realized by, for example, a storage medium such as a hard disk and stores various types of information. Further, a program for executing the processing according to the present invention is stored. The I / F unit 206 exchanges various signals with an external device. Note that output signals from the bubble sensor 114, the flow sensor 115, and the pressure sensor 123 are taken into the controller 110 via the I / F unit 206. The timer unit 204 measures various times.

The communication unit 207 communicates with the communication unit 211 attached to the medical staff. Note that the communication between the communication unit 207 and the communication unit 211 may be short-range wireless communication such as Bluetooth (registered trademark) or wireless communication using a wireless LAN such as Wi-Fi.

The control unit 205 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and realizes the above-described cardiopulmonary assist operation and the emergency transport determination process described below. It is assumed that a program for storing the information is stored (the description is omitted here).

The above is an explanation of an example of the functional configuration of the controller 110. Note that the functional configuration shown in FIG. 2 is merely an example, and a new configuration may be added, or unnecessary configuration may be omitted as appropriate. For example, the storage unit 201 (such as a hard disk) is not necessarily provided and may be omitted.

<3. Flow of emergency conveyance judgment process>
Hereinafter, a procedure of processing performed by the extracorporeal circulation device 100 according to the present embodiment will be described. The extracorporeal circulation apparatus 100 can operate by switching between a normal mode that operates without reducing power consumption and an emergency conveyance mode that operates while reducing power consumption during emergency conveyance.

Here, FIG. 6 is a diagram illustrating an example of a switching condition between the normal mode and the emergency transport mode. Reference numeral 601 denotes a control object, reference numeral 602 denotes control contents in the normal mode, and reference numeral 603 denotes control contents in the emergency transport mode.

As shown in FIG. 6, in the normal mode, the controller 110 receives power from the power cable and controls to charge until the battery reaches 100%. On the other hand, in the emergency transport mode, the battery is not charged, or the minimum predetermined amount required for transporting the patient from the emergency vehicle to a hospital bed (15-20 minutes operable state, battery capacity) However, it is controlled to charge only up to 30%, for example.

Also, the extracorporeal circulation device 100 can perform pulsation drive. The pulsation drive is a drive in which the controller 110 controls the drive motor 111 to periodically increase or decrease the number of rotations so that blood can easily reach the periphery. A pulsation occurs as the rotational speed periodically increases and decreases. The controller 110 performs control so that the pulsation drive can be selected in the normal mode. On the other hand, in the emergency transport mode, control is performed so that selection is not possible because power is consumed.

Furthermore, in the normal mode, the controller 110 controls the extracorporeal circulation device 100 so as to be selectable even if it is a function that consumes other power but is not essential for life support. On the other hand, in the emergency transport mode, since power is consumed, control is performed so that the function cannot be selected.

As described above, the extracorporeal circulation device 100 can operate by switching between the normal mode and the emergency transport mode depending on whether or not the emergency transport is being performed. Detailed processing for this switching will be described with reference to FIG.

FIG. 3 is a flowchart illustrating a procedure of emergency conveyance determination processing performed by the extracorporeal circulation device 100 according to the present embodiment.

In step S301, the controller 110 controls the extracorporeal circulation device 100 to operate in the normal mode.

In step S302, the controller 110 detects that the extracorporeal circulation device 100 is connected to a power source and AC power feeding is started. When the power connection is detected (S302; Yes), the process proceeds to step S303. On the other hand, when the power connection is not detected (S302; No), it waits.

In step S303, the controller 110 determines whether or not the power supply state of the AC power supply from the external power source is unstable. Here, the stability of the power supply state is determined based on the change in the AC power supply voltage from the external power supply. For example, when the AC power supply voltage is equal to or lower than the threshold value, it is determined that the power supply state is unstable. Further, it may be determined that the power supply is unstable when AC power supply is repeatedly turned ON / OFF a predetermined number of times within a predetermined time. When it is determined that the power supply state is unstable (S303; Yes), the process proceeds to step S304. On the other hand, when it is determined that the power supply state is not unstable (S303; No), the process proceeds to step S308.

In step S304, the controller 110 determines that the subject 130 is in the emergency transport mode, and confirms with the user whether or not the normal mode can be switched to the emergency transport mode. For example, a display asking whether switching is possible is displayed on the display unit 203, and the input of whether the switching is possible is accepted via the operation unit 202.

In step S305, the controller 110 determines whether switching is permitted by the user. When it is determined that switching is permitted (S305; Yes), the process proceeds to step S306. On the other hand, when it is determined that switching is not permitted (S305; No), the process proceeds to step S308.

In step S306, the controller 110 switches the extracorporeal circulation device 100 to the emergency transport mode. As described above, control such as prohibition of battery charging or impossibility of selection of pulsation drive is performed, and priority is given to power supply to other devices and functions necessary for life support.

In step S307, the controller 110 notifies the user that the extracorporeal circulation apparatus 100 has been switched to the emergency transport mode (currently operating in the emergency transport mode) by displaying on the display unit 203. Note that the notification method is not necessarily limited to the display on the display unit 203, but voice and sound from a speaker (not shown), light from an LED (not shown) (for example, red when in the emergency transport mode) The LED may be controlled to emit light), or a combination thereof may be used.

In step S308, the controller 110 operates the extracorporeal circulation device 100 in the normal mode because the power supply state is stable or switching is not permitted by the user. Thus, each process of the flowchart of FIG. 3 is completed.

As described above, in the present embodiment, the normal mode and the emergency transport mode are switched according to the stability of the power supply state from the external power source. Thereby, the limited electric power supply during emergency conveyance can be utilized effectively.

[Second Embodiment]
In the first embodiment, the configuration in which attention is paid to the power supply state of the AC power supply has been described in order to determine whether or not emergency transport is being performed. However, the condition for determining whether or not emergency transport is in progress is not limited to the first embodiment. In the present embodiment, an example will be described in which the normal mode and the emergency transport mode are switched according to the vibration of the extracorporeal circulation device. If the extracorporeal circulation device vibrates, it can be determined that there is a possibility that the extracorporeal circulation device is being used in an emergency vehicle during emergency transport (for example, moving on a road).

Hereinafter, a procedure of processing performed by the extracorporeal circulation device 100 according to the present embodiment will be described. Since the configuration of the extracorporeal circulation device 100 is the same as that of the first embodiment, detailed description thereof is omitted.

FIG. 4 is a flowchart illustrating a procedure of emergency conveyance determination processing performed by the extracorporeal circulation device 100 according to the present embodiment.

Here, in steps S401 to S402 and S406 to S410, the same processes as steps S301 to S302 and S304 to S308 of FIG.

In step S403, the controller 110 detects the vibration of the extracorporeal circulation device 100. The extracorporeal circulation device 100 is vibrated due to vibrations when an ambulance such as an ambulance or a doctor helicopter moves. For example, the extracorporeal circulation device 100 includes an acceleration sensor (not shown) and detects vibration by the acceleration sensor.

In step S404, the controller 110 determines whether or not the detected vibration amplitude is greater than or equal to a threshold value. As this threshold value, vibration during movement of the vehicle is measured, and an appropriate value is set in advance.

If it is determined that the amplitude is greater than or equal to the threshold (S404; Yes), the process proceeds to step S405. On the other hand, when it determines with an amplitude being less than a threshold value (S404; No), it progresses to step S410 and operates the extracorporeal circulation apparatus 100 with a normal mode.

In step S405, the controller 110 determines whether or not the timer unit 204 has continued to vibrate with an amplitude greater than or equal to the threshold value for a predetermined time or more. When it determines with having continued more than predetermined time (S405; Yes), it progresses to step S406 and performs control which switches to emergency conveyance mode. On the other hand, when it determines with having not continued more than predetermined time (S405; No), it progresses to step S410 and operates the extracorporeal circulation apparatus 100 with a normal mode. Thus, the processes in the flowchart of FIG. 4 are completed.

As described above, in this embodiment, the normal mode and the emergency transport mode are switched according to the vibration of the apparatus. Thereby, the limited electric power supply during emergency conveyance can be utilized effectively.

Also, the first embodiment and the second embodiment may be combined. In other words, using both the stability of the power supply state and the vibration of the device as criteria, switch to the emergency transport mode when both conditions are satisfied (AC power supply is unstable and vibration with an amplitude exceeding the threshold continues for a predetermined time). Also good. This makes it possible to determine that the emergency transport is being performed with higher accuracy.

[Third Embodiment]
The conditions for determining whether or not emergency transport is in progress are not limited to the first and second embodiments. In the present embodiment, an example will be described in which sound output from an emergency vehicle such as a siren is detected and the normal mode and the emergency transport mode are switched in accordance with the detection.

FIG. 5 is a flowchart illustrating a procedure of emergency conveyance determination processing performed by the extracorporeal circulation device 100 according to the present embodiment.

Here, in steps S501 to S502 and S504 to S508, the same processes as steps S301 to S302 and S304 to S308 in FIG.

In step S503, the controller 110 determines whether or not a sound output from a rescue vehicle such as a siren is detected. For example, it is determined that the sound output of the siren has been detected when a predetermined overlap condition is satisfied as compared with information of a frequency band specific to the siren held in advance. When it is determined that sound output has been detected (S503; Yes), the process proceeds to step S504, and the extracorporeal circulation device 100 is switched from the normal mode to the emergency transport mode. On the other hand, when it is determined that no sound output is detected (S503; No), the process proceeds to step S508, and the extracorporeal circulation device 100 is operated in the normal mode.

As described above, in this embodiment, the normal mode and the emergency transport mode are switched according to the detection of the sound output of the emergency vehicle. Thereby, the limited electric power supply during emergency conveyance can be utilized effectively.

Further, the first embodiment and the third embodiment may be combined. In other words, both the stability of the power supply state and the detection of the sound output are used as the determination criteria, and when both conditions are satisfied (AC power supply is unstable and the sound output of the emergency vehicle is detected), the emergency transport mode may be switched. . This makes it possible to determine that the emergency transport is being performed with higher accuracy.

Furthermore, all the determination conditions of the first to third embodiments may be combined. That is, when all the conditions are satisfied (AC power feeding is unstable, vibration detection and sound output from the emergency vehicle are detected), the emergency transport mode may be switched. This makes it possible to determine that the emergency transport is being performed with higher accuracy.

In the first to third embodiments, the process of automatically determining whether or not the extracorporeal circulation device itself is in emergency transport and switching between the normal mode and the emergency transport mode has been described. On the other hand, the user may manually switch the operation mode of the extracorporeal circulation device. In that case, when using the extracorporeal circulation device 100 in an emergency vehicle, a user such as an ambulance crew directly operates the operation unit 202 (for example, a hard switch) shown in FIG. 2 to switch to the emergency transport mode. Alternatively, switching is performed by a touch operation on the display unit 203.

This makes it possible to take manual switching measures when the switch to the emergency transport mode has not been made for some reason, so that the limited power supply during the emergency transport can be effectively utilized.

The present invention is not limited to the above embodiment, and various changes and modifications can be made without departing from the spirit and scope of the present invention. Therefore, in order to make the scope of the present invention public, the following claims are attached.
