[0002] A ventricular assist device is used to assist blood circulation of a patient. An interventional pump system, a blood pump and a console are core components of the ventricular assist device. In the working process, the interventional pump is placed into the heart through the skin by a peripheral blood vessel, and the console controls the blood pump to run in response to a related control operation to provide different degrees of circulation assistance to the patient to maintain blood circulation of important organs of the patient.

In the related art, the electronic components in the interventional pump are numerous and the internal structure is complex. Moreover, the interventional pump needs to be inserted into the target object through the skin and cannot be reused, and thus needs to be discarded after each use. Therefore, the multiple electronic components in the interventional pump are also discarded and thus are subject to wear and tear, such as the motor and the motor controller.

Referring to FIG. 3, the control system of the ventricular assist device according to the present application includes a blood pump monitoring module 10, a motor monitoring module 20, a console control module 30, and a pump system control module 40. The blood pump monitoring module 10 is arranged on the blood pump 1, and the motor monitoring module 20, the console control module 30, and the pump system control module 40 are arranged on the control device 2. That is, the blood pump monitoring module 10 is arranged on the consumable side, and the motor monitoring module 20, the console control module 30, and the pump system control module 40 are arranged on the non-consumable side, and the consumable side and the non-consumable side are detachably connected.

[0095] Referring to FIG. 3, the pump system control module 40 is connected with the blood pump monitoring module 10 through the motor monitoring module 20, and is configured to at least control the blood pump 1 to operate, and determine the corresponding ventricular assist data of the blood pump 1 according to the blood pump sensing data and / or the blood pump driving data. Optionally, the ventricular assist data at least includes data for representing the physiological state of the patient and the operating state of the blood pump 1. Optionally, the ventricular assist data includes at least one of the following: intervention position data, blood pump flow data, and ventricular pressure data. The intervention position data represents the actual position of the blood pump 1 (e.g. the pump head) in the target object; the blood pump flow data represents the blood flow corresponding to the blood pump 1; and the ventricular pressure data represents the ventricular pressure of the patient during the use of the blood pump 1. In this embodiment, the pump system control module 40 can be configured to store a ventricular assist prediction model, which takes the blood pump sensing data and / or the blood pump driving data as input, simulates the ventricular assist data and outputs, and can be optimized by training a large number of input data and output data. During the use of the device, the blood pump sensing data and / or the blood pump driving data actually collected by the blood pump monitoring module 10 and the motor monitoring module 20 are imported into the trained ventricular assist model to predict the above-mentioned ventricular assist data, so as to facilitate the user to check the difficult-to-detect ventricular assist parameters such as the above-mentioned intervention position, blood pump flow, and ventricular pressure.

[0096] The console control module 30 is connected with the pump system control module 40, and is configured to process the human-computer interaction operation and the system control operation of the control device 2.

[0097] In the present application, the control functions of the control system are mainly arranged in the console control module 30 and the pump system control module 40, and the blood pump monitoring module 10 and the motor monitoring module 20 mainly realize data monitoring functions, forming a control system based on an external motor coupled driving blood pump. Specifically, the pump system control module 40 is responsible for controlling the operation of the driving device 22 and the blood pump 1, and receives the data (i.e. blood pump sensing data and blood pump driving data) returned by the blood pump monitoring module 10 and the motor monitoring module 20, imports the blood pump sensing data and / or blood pump driving data into the trained ventricular assist model, calculates ventricular assist data such as intervention position data, blood pump flow data and ventricular pressure data, and sends at least one of the blood pump sensing data, and / or blood pump driving data, and / or ventricular assist data to the console control module 30 for display through the console 21. By arranging the control function in the external control device, the non-consumable part, calculating the ventricular assist data in the external control module (pump system control module 40), providing a reference basis for blood pump operation, and retaining part of the necessary monitoring function on the blood pump side, the number and structural complexity of electronic components in the blood pump consumable can be effectively reduced, the processing cost and material cost of the blood pump are reduced, the structure of the blood pump consumable is simplified, the problem of complex structure and high loss cost of the blood pump consumable part in the related art is solved, and the product use cost is reduced.

[0099] FIG. 4 is a structural schematic view of another ventricular assist device provided by the embodiment of the present application. Referring to FIG. 4, the control device 2 includes a console 21, a blood pump driving device 221 and a flush pump driving device 222; the console 21 is connected with the blood pump driving device 221 through a first connecting line 223, and the flush pump driving device 222 is carried on the console 21. The blood pump driving device 221 is coupled with the blood pump 1.

[0100] The above-mentioned driving device 22 includes the above-mentioned blood pump driving device 221 and the flush pump driving device 222.

[0101] Optionally, the length of the first connecting line 223 meets the distance requirement between the device operation area and the blood pump operation area. The device operation area refers to an area in the operating space where the console 21 and the flush pump driving device 222 are placed, such as an area outside the operating table, an area where the device placement table or trolley is located; the blood pump operation area refers to a sterile surgical operation area in the operating space where the blood pump 1 intervenes in the target object in the body, such as an operating table.

[0102] It should be noted that the length of the first connecting line is not limited in the embodiments of the present application, and can be determined according to the actual product use scenario.

[0103] Optionally, the blood pump driving device 221 includes but is not limited to a driving motor.

[0104] Referring to FIG. 4, the blood pump driving device 221 is connected with the blood pump 1. The blood pump monitoring module 10 is installed in the driving catheter handle 11 of the blood pump 1, and the driving catheter handle 11 is plug-in connectable with the blood pump driving device 221. When the ventricular assist device is in a working state, the blood pump driving device 221 is coupled with the driving catheter handle 11, and the blood pump driving device 221 drives the impeller in the pump head to rotate. The rotation speed of the blood pump driving device 221 can be set through the interactive device (such as a knob, or a key, or a display screen) of the console 21. When the ventricular assist device is in a non-working state, the blood pump driving device 221 is disconnected from the driving catheter handle 11 of the blood pump 1. Optionally, in the non-working state, the blood pump driving device 221 and the first connecting line 223 can be stored in the console 21, or in a separately arranged storage device.

[0105] FIG. 5 is a structural schematic view of a control system of another ventricular assist device provided by the embodiments of the present application. Referring to FIG. 5, the motor monitoring module 20 is arranged in the blood pump driving device 221. In the use process, the pump system control module 40 can detect whether the blood pump driving device 221 abnormally operates according to the blood pump driving data of the motor monitoring module 20, such as excessively high motor temperature, or abnormal motor rotation speed, or excessively large current, and the pump system control module 40 can further send an alarm signal of the abnormal blood pump driving device 221 to the console 21; the pump system control module 40 is arranged in the flush pump driving device 222; and the console control module 30 is arranged in the console 21.

[0106] The pump system control module 40 is used to control the blood pump driving device 221 to operate. In the ventricular assist device, the blood pump is consumable, and the blood pump driving device 221 needs to rotate at a high speed and stably (up to tens of thousands of revolutions), and has high quality requirements and is a vulnerable component. If the vibration generated by the blood pump driving device 221 exceeds the acceptable range, even if it can still operate, the blood pump driving device 221 needs to be replaced. In the ventricular assist device shown in FIG. 4, the flush pump driving device 222 is fixedly arranged on the control console 21, and the flush pump driving device 222 and the control console 21 have small wear and tear. Compared with the flush pump driving device 222 and the control console 21, the blood pump driving device 221 is provided with a driving motor, and the driving motor needs to rotate at a high speed and stably to maintain a high blood pumping volume. If the driving unit of the driving motor is arranged in the blood pump driving device 221, the motor may be abnormal but the driving unit is normal. If the driving unit is arranged in the blood pump driving device 221, the blood pump driving device 221 needs to be replaced as a whole. Therefore, in the embodiment of the present application, the pump system control module 40 arranged in the flush pump driving device 222 is used to control the operation of the blood pump driving device 221. When the blood pump driving device 221 is damaged (such as motor vibration and motor damage), the waste of the related driving unit (such as the motor driving unit) of the blood pump driving device 221 can be reduced, only the simple blood pump driving device 221 needs to be replaced, the number of electronic devices and the complexity of the circuit module in the vulnerable component of the blood pump driving device 221 are effectively reduced, the internal structure of the blood pump driving device 221 is simplified, and the cost of the blood pump driving device 221 is reduced, so that the use cost of the product is further reduced.

[0107] In summary, the technical scheme provided in the embodiment of the present application not only simplifies the structure of the blood pump consumable, but also simplifies the structure of the vulnerable equipment, and reduces the cost of the consumable and the vulnerable equipment in the ventricular assist device as a whole, and further reduces the use cost of the ventricular assist device product.

[0108] Referring to FIG. 5, the control device 2 further comprises a flush pump 224, the flush pump 224 is connected with the flush pump driving device 222, and the pump system control module 40 is further used to control the operation of the flush pump 224. Specifically, the flush pump 224 can be a peristaltic pump, which realizes the transportation and control function of the flush fluid by extruding the flush pipeline, and prevents blood from entering the driving catheter 13 (see FIG. 2) to generate thrombus.

[0109] Optionally, the flush pump driving device 222 is provided with the flush pump 224.

[0110] Optionally, the control console 21 and the pump system control module 40 can be connected in communication through CAN communication mode, the pump system control module 40 and the motor monitoring module 20 can be connected in communication through RS485 communication mode, and the blood pump driving device 221 and the blood pump monitoring module 10 can be connected in communication through serial communication mode. Optionally, the serial communication mode can be 3.3V serial communication mode.

[0111] FIG. 6 is a structural schematic diagram of a control system of another ventricular assist device according to an embodiment of the present application, which exemplarily shows a schematic diagram of the internal structure and connection relationship of each module in the control system.

[0112] Referring to FIG. 6, the motor monitoring module 20 comprises a first controller unit 201 and a communication interface module 202, and the communication interface module 202 is configured to realize the communication connection between the pump system control module 40 and the motor monitoring module 20 and the communication connection between the pump system control module 40 and the blood pump monitoring module 10.

[0113] Optionally, referring to FIG. 6, the motor monitoring module 20 further comprises a first storage unit 205 connected with the first controller unit 201, and the first controller unit 201 is further configured to acquire the motor running duration; and the first storage unit 205 is configured to store the motor running duration. Specifically, the first storage unit 205 is configured to record the cumulative motor running duration of the driving motor 225. Since the driving motor in the blood pump driving device has a service life, it needs to be replaced after reaching the set service time limit, and therefore the cumulative motor running duration of the driving motor needs to be recorded in the device. However, although the blood pump driving device and the flush pump driving device are used in combination, they are detachably connected, and the flush pump driving device cannot only drive one unique blood pump driving device. If the cumulative motor running duration of each blood pump driving device connected with the flush pump driving device is stored by the flush pump driving device, the data structure complexity of the flush pump driving device will be increased, and a lot of useless data may be stored, wasting storage space. By storing the cumulative motor running duration of the blood pump driving device itself, the flush pump driving device or the control console side does not need to store it, and it is not necessary to distinguish the cumulative motor running duration of different blood pump driving devices. In the case that the motor running duration exceeds the set duration, the control console can issue a motor replacement prompt to remind the operator to replace the motor, thereby improving the operation reliability of the driving motor 225.

[0114] Preferably, referring to FIG. 6, the motor monitoring module 20 further comprises a temperature detection unit 206 and / or a rotating speed detection unit 207 connected with the first controller unit 201, the temperature detection unit 206 is used to obtain the motor temperature (for example, the coil temperature of the driving motor 225), and the rotating speed detection unit 207 is used to obtain the motor rotating speed. By reading the motor temperature and / or the motor rotating speed, or identifying the motor operating condition according to the motor temperature and / or the motor rotating speed, the console can trigger the motor abnormality alarm when the motor temperature exceeds the first temperature range, or the motor rotating speed exceeds the first rotating speed range.

[0115] Referring to FIG. 6, the blood pump monitoring module 10 comprises a second controller unit 101, and a second storage unit 102 and a sensor detection unit 103 connected with the second controller unit 101 respectively; wherein the second storage unit 102 is used to store the blood pump calibration data, the sensor detection unit 103 comprises at least one of the following: a flush pressure sensor 104, an arterial pressure sensor 105 and an environmental pressure sensor 106; the second controller unit 101 is in communication connection with the pump system control module 40. Specifically, the communication channel between the second controller unit 101 and the pump system control module 40 is arranged in the motor monitoring module 20. By arranging the above main circuit modules in the blood pump monitoring module, the structure of the blood pump monitoring module can be simplified, the size of the driving catheter handle can be reduced, the holding is facilitated, and the cost is reduced while meeting the basic data monitoring requirements of the ventricular assist device.

[0116] Referring to FIG. 6, the control device 2 comprises a flush pump 224 and a driving motor 225, the driving motor 225 is used to drive the blood pump 1 to operate, and the flush pump 224 is used to drive the flush fluid in the blood pump 1. Optionally, the flush pump 224 comprises but is not limited to an infusion pump and a circulation pump. Referring to FIG. 6, the pump system control module 40 at least comprises a flush pump driving unit 402 used to drive the flush pump 224 to operate, a flush pump monitoring unit 403 used to obtain the flush pump operating data, a motor driving unit 404 used to drive the driving motor 225 to operate, a driving monitoring unit 405 used to obtain the driving unit operating data of the motor driving unit 404 and the flush pump driving unit 402, and a third controller unit 401 connected with the flush pump driving unit 402, the flush pump monitoring unit 403, the motor driving unit 404 and the driving monitoring unit 405.

[0117] By arranging the flush pump driving unit 402, the flush pump monitoring unit 403, the motor driving unit 404 and the driving monitoring unit 405 in the pump system control module 40 and in the flush pump driving device 222, it is not necessary to arrange the motor driving unit and the driving monitoring unit in the blood pump driving device, the structure of the blood pump driving device is simplified, and the cost of the blood pump driving device is reduced.

[0118] Optionally, the pump system control module 40 further comprises at least one of a bubble detection unit 406, a third storage unit 407, a third communication interface chip 408 and a power supply unit 409; the bubble detection unit 406 is connected with the third controller unit 401, for obtaining bubble detection data of the flushing pipeline and sending the bubble detection data to the third controller unit 401; the third storage unit 407 is connected with the third controller unit 401, for receiving and storing at least one of the bubble detection data, the flushing pump operation data and the driving unit operation data. By arranging the bubble detection unit 406 in the pump system control module 40, the bubble detection unit can be effectively reused without arranging it in the blood pump consumable part.

[0119] The first end of the third communication interface chip 408 is in communication connection with the third controller unit 401, the second end of the third communication interface chip 408 is in communication connection with the communication interface module 202 of the motor monitoring module 20, and the third communication interface chip 408 is also in communication connection with the communication interface module of the blood pump monitoring module 10. The above-mentioned third communication interface chip 408 includes the communication chip in the pump system control module 40, which can be one or more. The pump system control module as an embedded real-time control platform, as a communication host, controls and manages the blood pump driving device and the blood pump two slaves, periodically sends messages to the blood pump driving device and the blood pump, and the message content includes the control message sent by the communication host and the state message returned by the slave. Among them, the above-mentioned blood pump monitoring module 10 and the motor monitoring module 20 are two slaves in parallel. Although the flushing pump driving device, the blood pump driving device and the blood pump are connected in sequence, the pump system control module is still in direct communication with the blood pump monitoring module, and the communication connection line between the pump system control module and the blood pump monitoring module passes through the motor monitoring module, which improves the stability of the system communication. When the blood pump driving device is abnormal or the motor monitoring module is abnormal, it does not affect the communication between the pump system control module and the blood pump monitoring module, and ensures the normal transmission of the blood pump monitoring data.

[0120] The input end of the power supply unit 409 is electrically connected with the power management module 323 arranged in the console control module 30, the first output end of the power supply unit 409 is electrically connected with the power supply end of the third controller unit 401, and the second output end of the power supply unit 409 is electrically connected with the power supply end of the blood pump monitoring module 10 through the power supply isolation unit (i.e. the third isolation unit 210) arranged in the motor monitoring module 20. Preferably, the third communication interface chip 408 is an RS485 interface chip. Similarly, in the case that the flush pump driving device, the blood pump driving device and the blood pump are sequentially connected, the pump system control module is still directly connected with the blood pump monitoring module for power supply, the power supply connection line between the pump system control module and the blood pump monitoring module passes through the motor monitoring module, the stability of the system power supply is improved, when the blood pump driving device is abnormal or the motor monitoring module is abnormal, the blood pump monitoring module and the pump system control module are not affected, and the normal transmission of the blood pump monitoring data is ensured. Moreover, the power supply connection line between the pump system control module and the blood pump monitoring module is provided with an isolation unit, the blood pump is provided with power supply isolation, so that the safety of the target object is ensured when the blood pump works in the target object, and the influence of abnormal electrical signals on the life safety of the target object is prevented.

[0121] Referring to FIG. 6, the motor monitoring module 20 includes a plurality of communication channels, and the plurality of communication channels include a first communication channel I and a second communication channel II; wherein the first communication channel I is used for communication connection between the pump system control module 40 and the motor monitoring module 20; the second communication channel II is used for communication connection between the pump system control module 40 and the blood pump monitoring module 10, and the second communication channel II is provided with a first isolation unit 208, and the first isolation unit 208 is used for providing electrical isolation between the blood pump monitoring module 10 and the pump system control module 40.

[0122] The pump system control module is an embedded real-time control platform and a communication host, controls and manages two slaves, i.e. the motor monitoring module and the blood pump monitoring module, through two parallel communication channels in the motor monitoring module, and periodically sends messages to the blood pump driving device and the blood pump. The blood pump monitoring module and the motor monitoring module are two parallel slaves. Although the flush pump driving device, the blood pump driving device and the blood pump are sequentially connected, the pump system control module can still directly communicate with the blood pump monitoring module through the two communication channels arranged in the motor monitoring module, the communication connection line between the pump system control module and the blood pump monitoring module passes through the motor monitoring module, the stability of the system communication is improved, when the blood pump driving device is abnormal or the motor monitoring module is abnormal, the blood pump monitoring module and the pump system control module are not affected, and the normal transmission of the blood pump monitoring data is ensured.

[0123] And, since some sensors in the blood pump need to detect blood pressure, when the blood pump is inserted into the body, it will be in fluid communication with the blood in the target object's body, forming a conductive channel. The communication channel between the pump system control module and the blood pump monitoring module is provided with an isolation unit, which provides power isolation for the blood pump, thereby ensuring the safety of the target object when the blood pump is working in the target object's body, preventing abnormal electrical signals from affecting the life safety of the target object.

[0124] Referring to FIG. 6, the plurality of communication channels further include a third communication channel III for communication connection between the blood pump monitoring module 10 and the motor monitoring module 20, and the third communication channel III is provided with a second isolation unit 209 for providing electrical isolation between the blood pump monitoring module 10 and the motor monitoring module 20.

[0125] In some embodiments, the blood pump monitoring module 10 and the motor monitoring module 20 are in communication connection, and the blood pump monitoring module detects whether the blood pump is in place by detecting the communication signal, in which case the second isolation unit is provided between the blood pump monitoring module and the motor monitoring module 20, thereby providing electrical isolation therebetween to ensure the safety of the target object when the blood pump is working in the target object's body, preventing abnormal electrical signals from affecting the life safety of the target object.

[0126] Specifically, the first communication channel I and the second communication channel II can be RS485 communication channels, and the third communication channel III can be a serial communication channel, and the first isolation unit 208 and the second isolation unit 209 at least include a communication isolation element, which provides isolated communication signals on the side of the blood pump 1 by setting the communication isolation element on the second communication channel II and the third communication channel III, thereby improving the communication protection level of the intervention side.

[0127] Referring to FIG. 6, the motor monitoring module 20 further includes a power supply channel IV for power supply connection between the pump system control module 40 and the blood pump monitoring module 10; the power supply channel IV is provided with a third isolation unit 210 for providing two-stage electrical isolation between the pump system control module 40 and the blood pump monitoring module 10. Also, since some sensors in the blood pump need to detect blood pressure, when the blood pump is inserted into the body, it will be in fluid communication with the blood in the target object's body, forming a conductive channel. The communication channel between the pump system control module and the blood pump monitoring module is provided with an isolation unit, which provides power isolation for the blood pump, thereby ensuring the safety of the target object when the blood pump is working in the target object's body, preventing abnormal electrical signals from affecting the life safety of the target object.

[0128] In some embodiments, the console control module 30 is provided with a fourth isolation unit 301 configured to provide one-stage electrical isolation between the input power supply and the console control module 30. Preferably, the control device 2 comprises an AC / DC conversion module, the console control module 30 is connected with the AC power supply through the AC / DC conversion module, and the fourth isolation unit is arranged in the AC / DC conversion module. Specifically, the fourth isolation unit 301 performs voltage conversion and one-stage electrical isolation on the AC voltage provided by the input power supply, and transmits the converted and isolated voltage to the power supply unit 409 of the pump system control module 40. The power supply unit 409 performs voltage conversion processing on the received voltage, and transmits the converted voltage to the blood pump monitoring module 10 through the third isolation unit 210. The fourth isolation unit 301 and the third isolation unit 210 form a two-stage power supply isolation structure, which can improve the power supply protection level of the intervention side, reduce the risk of leakage of the intervention side, and improve the safety performance of the product.

[0129] Fig. 7 is a structural schematic diagram of a motor monitoring module provided in an embodiment of the present application. Referring to Figs. 6 and 7, the motor monitoring module 20 is provided with a first electrical connector 20P, and the blood pump monitoring module 10 is provided with a second electrical connector 10P. The first electrical connector 20P and the second electrical connector 10P are elastically contact-connected, and the wear resistance of the first electrical connector 20P is better than that of the second electrical connector 10P. Specifically, the first electrical connector 20P is used to connect the communication channels (such as the first communication channel I, the second communication channel II, and the third communication channel III) and / or the power supply channels of the motor monitoring module 20, and the second electrical connector 10P is used to connect the communication channels and / or the power supply channels of the blood pump monitoring module 10. When the first electrical connector 20P and the second electrical connector 10P are plug-connected, the power supply loop and the communication loop between the blood pump monitoring module 10 and the motor monitoring module 20 are communicated. In this embodiment, the first electrical connector 20P and the second electrical connector 10P can be spring needle connectors, that is, the spring needle connector is used to electrically connect the blood pump monitoring module 10 and the motor monitoring module 20. Preferably, the first electrical connector 20P is a female head of the spring connector, and the second electrical connector 10P is a male head of the spring connector. Since the male head of the spring connector is more prone to damage than the female head of the spring connector, the male head of the spring connector is arranged on the side of the blood pump 1 (i.e., the consumable), the motor monitoring module is arranged on the side of the blood pump driving device, and is reused. The male head of the spring connector which is prone to damage is arranged on the side of the consumable, and the female head which is not prone to damage is arranged on the side of the non-consumable. In this way, the quality and reliability of the side of the non-consumable can be improved, and the communication stability of the system can be improved.

[0130] In some embodiments, the motor monitoring module 20 is further configured to determine a blood pump in-place detection result according to the communication signal between the motor monitoring module 20 and the blood pump monitoring module 10, wherein the blood pump in-place detection result includes one of a blood pump in-place and a blood pump not in-place, the blood pump in-place indicating that the blood pump 1 is successfully connected with the control device 2, and the blood pump not in-place indicating that the blood pump 1 is not successfully connected with the control device 2. In the related art, a separate in-place detection pin is required to detect the in-place of the blood pump, while in the embodiments of the present application, the motor monitoring module multiplexes the communication signal to detect the in-place of the blood pump, thereby reducing the in-place detection pin and reducing the product size. Specifically, the blood pump driving device 221 and the blood pump 1 both need to be held by an operator during use, as shown in FIG. 4, since the blood pump driving device 221 and the blood pump 1 are respectively provided with rotating driving assemblies that are coupled to each other at the axial center, the connector between the two needs to be arranged in the annular gap between the rotating driving assemblies and the outer peripheral sidewalls of the blood pump driving device 221 and the blood pump 1, and reducing one in-place detection pin can effectively reduce the size of the annular gap, thereby reducing the diameters of the blood pump driving device 221 and the driving catheter handle 11, making it more convenient for the operator to hold, and thereby improving the operation convenience.

[0131] Specifically, referring to FIGS. 6 and 7, the communication signal between the motor monitoring module 20 and the blood pump monitoring module 10 is a 3.3V serial communication signal, and thus the in-place of the blood pump 1 can be detected by detecting the level state of the communication signal between the motor monitoring module 20 and the blood pump monitoring module 10. For example, when the motor monitoring module 20 detects that the communication signal between the motor monitoring module 20 and the blood pump monitoring module 10 is a high-level signal, it is determined that the blood pump is in place, i.e., the blood pump 1 is successfully connected with the control device 2; when the motor monitoring module 20 detects that the communication signal between the motor monitoring module 20 and the blood pump monitoring module 10 is a low-level signal, it is determined that the blood pump is not in place, i.e., the blood pump 1 is not successfully connected with the control device 2. By detecting the connection state between the blood pump and the control device through the communication signal between the motor monitoring module and the blood pump monitoring module, both the communication function and the blood pump in-place detection function can be achieved, without the need to separately increase a dedicated detection pin to perform blood pump in-place detection, thereby reducing the number of connection pins between the motor monitoring module and the blood pump monitoring module, reducing the insertion fitting cross-sectional length between the blood pump and the control device, reducing the overall volume of the blood pump, and reducing the difficulty of insertion fitting alignment.

[0132] Optionally, FIG. 8 is a schematic diagram of a circuit connection structure of a motor monitoring module according to an embodiment of the present application. Referring to FIG. 8, a first communication pin pin1 of the blood pump monitoring module 10 is connected to a second communication pin pin2 of the motor monitoring module 20, and the motor monitoring module 20 and the blood pump monitoring module 10 adopt periodic serial communication. The motor monitoring module 20 is configured to: acquire a communication signal corresponding to the second communication pin and a third duration of the communication signal in a first state; and determine the in-position detection result according to the signal state of the communication signal and the third duration.

[0133] Preferably, the present application uses low level to represent not in position and high level to represent in position. Specifically, when the motor monitoring module 20 and the blood pump monitoring module 10 are in a non-connected state, the signal state of the communication signal of the second communication pin detected by the motor monitoring module 20 is a low level state, and the blood pump is not in position. After the motor monitoring module 20 and the blood pump monitoring module 10 are connected, the signal state of the communication signal of the second communication pin detected by the motor monitoring module 20 is a high level state. After the motor monitoring module 20 and the blood pump monitoring module 10 are connected, the motor monitoring module 20 and the blood pump monitoring module 10 perform periodic communication, and the signal state of the second communication pin detected by the motor monitoring module 20 is high or low, and it is not suitable to continue using high and low levels as in-position detection. In order to take into account the case that the serial transmission tx signal level is high or low during communication, and considering that the serial port is high in the idle state, the in-position judgment condition is modified to detect whether the low level lasts for a period of time (the detection time is set according to the communication period), so that the interventional pump can be accurately and reliably detected whether it is in position when the interventional pump is not connected, connected, disconnected after connection is completed, and reconnected. Therefore, by combining the signal state of the communication signal and the third duration of the communication signal in the first state for in-position detection, both communication function and in-position detection function are realized.

[0134] Referring to FIG. 7 and FIG. 8, the motor monitoring module 20 comprises a first controller unit 201 and a communication interface module 202, the first communication pin pin1 of the blood pump monitoring module 10 is connected with the communication interface module 202 and the first controller unit 201 respectively, and similarly, the second communication pin pin2 of the motor monitoring module 20 is connected with the communication interface module 202 and the first controller unit 201 respectively. In the embodiment, the communication signal is a communication transmission signal (such as the above-mentioned tx signal). Alternatively, the first communication pin pin1 and the second communication pin pin2 are communication transmission pins. The first communication pin is connected with the power supply VDD through a pull-up resistor R10; the second communication pin pin2 is grounded through a pull-down resistor R20; the first state at least comprises a low level state; the motor monitoring module 20 is configured to: when the first state is a low level state, and the third duration in the low level state is greater than the first duration, determine that the blood pump is not in place. Preferably, the power supply VDD can be used to provide a 3.3V direct current power supply voltage. The resistance value of the pull-up resistor R10 can be less than the resistance value of the pull-down resistor R20. In the embodiment, the first duration is set according to the communication period between the blood pump monitoring module 10 and the motor monitoring module 20. Preferably, the first duration can be set to 100 milliseconds.

[0135] Specifically, referring to FIG. 8, the communication transmitting pin (i.e., the first communication pin pin1) of the blood pump monitoring module 10 is connected to the second communication interface chip 204 and the second communication pin pin2 of the first controller unit 201 on the circuit board of the motor monitoring module 20 at the same time. Periodic serial communication is adopted between the first communication pin pin1 and the second communication pin pin2. The first controller unit 201 detects the signal state of the second communication pin pin2 in real time. Before the blood pump 1 is connected with the control device 2, the second communication pin pin2 is pulled down to low level by the pull-down resistor R20, at this time, the signal state of the communication transmitting signal detected by the first controller unit 201 is low level state, and it is determined that the blood pump is not in place; when the blood pump 1 is connected with the control device 2, the first communication pin pin1 is pulled up to high level by the pull-up resistor R10, at this time, the signal state of the communication transmitting signal detected by the first controller unit 201 is high level state, and it is determined that the blood pump is in place. After the periodic communication between the blood pump 1 and the control device 2 starts, at this time, the signal state of the communication transmitting signal detected by the first controller unit 201 is high or low, and the communication transmitting signal is in high level state in the idle state, if the signal state of the communication transmitting signal detected by the first controller unit 201 is low level state, and the third duration in low level state is greater than the first duration (for example, 100 milliseconds), it is determined that the blood pump is not in place; if the signal state of the communication transmitting signal detected by the first controller unit 201 is high level state, or, the third duration in low level state is less than or equal to the first duration (for example, 100 milliseconds), it is determined that the blood pump is in place. By setting the pull-up resistor and the pull-down resistor, the reliability of the signal detection result is improved, the communication gap, i.e., the signal state and the duration of the communication signal in the idle state of the serial communication, is used for in-place detection, the in-place detection of the blood pump in different scenarios such as no connection, connection completion, and reconnection after connection completion and disconnection can be realized, no additional detection pin is needed, the structure is simplified, and it is convenient to use.

[0136] Preferably, referring to FIG. 8, the communication interface module 202 comprises a first communication interface chip 203 and a second communication interface chip 204. The first end of the first communication interface chip 203 is connected with the pump system control module 40, the second end of the first communication interface chip 203 is connected with the first controller unit 201, and the first communication interface chip 203 is arranged in the first communication channel I. The first end of the second communication interface chip 204 is connected with the pump system control module 40, the second end of the second communication interface chip 204 is connected with the blood pump monitoring module 10 through the first isolation unit 208, and the second communication interface chip 204 and the first isolation unit 208 are arranged in the second communication channel II. Referring to FIG. 8, the third controller unit 401 of the pump system control module 40 is in communication connection with the motor monitoring module 20 through the third communication interface chip 408 (for example, an RS485 interface chip) and the first communication interface chip 203 (for example, an RS485 interface chip), and the third controller unit 401 is also in communication connection with the blood pump monitoring module 10 through the third communication interface chip 408 (for example, an RS485 interface chip), the second communication interface chip 204 (for example, an RS485 interface chip) and the first isolation unit 208. The 485 interface chip (i.e., the second communication interface chip 204) of the blood pump monitoring module 10 is arranged on the circuit board of the motor monitoring module 20.

[0137] In some embodiments, the blood pump monitoring module 10 is configured to store blood pump calibration data, wherein the blood pump calibration data characterizes the operating characteristics of the target components in the blood pump 1. The target components of the present application include but are not limited to the flush pressure sensor 104, the arterial pressure sensor 105, the environmental pressure sensor and the pump head. Optionally, the blood pump calibration data comprises at least one of the following: hydraulic characteristics data of the blood pump 1, sensor characteristic data. The hydraulic characteristics data characterizes the fluid mechanics parameters and performance indicators of the target components during the operation of the blood pump 1. For different pump heads, although the structural design is the same, there are slight differences in production process or assembly, which leads to slight differences in the hydraulic performance of each blood pump. The above-mentioned hydraulic characteristics data can be some coefficients related to the hydraulic performance indicators (such as flow rate, pressure difference), which facilitates the calibration of the flow rate, interventional position, pressure and other data in the ventricular assist data. The sensor characteristic data characterizes the sensor physical characteristic data, including but not limited to the temperature coefficient, pressure coefficient, humidity coefficient and the like related to the detection value. It should be noted that the blood pump calibration data corresponding to each blood pump is different, and the blood pump calibration data corresponding to each blood pump 1 can be obtained and stored by the skilled person in the art through testing calibration.

[0138] Correspondingly, the pump system control module 40 of the application is configured to determine ventricular assist data according to blood pump calibration data and blood pump sensing data and / or blood pump driving data. Specifically, referring to FIG. 6, the blood pump calibration data is stored in the second storage unit 102. During use of the blood pump 1, the pump system control module 40 reads the blood pump calibration data (such as the hydraulic characteristics data and sensor characteristics data of the blood pump 1) stored in the second storage unit 102 based on the second communication channel II, reads the blood pump sensing data (such as the flushing pressure data, arterial pressure data and environmental pressure data) collected by the blood pump monitoring module 10 based on the second communication channel II, and reads the blood pump driving data (such as the motor running time, motor speed and motor temperature) collected by the motor monitoring module 20 based on the first communication channel I. The pump system control module 40 imports the blood pump sensing data and / or blood pump driving data actually collected by the blood pump monitoring module 10 and the motor monitoring module 20 into the pre-trained ventricular assist model, calculates ventricular assist data, and then optimizes and calibrates the intervention position data, blood pump flow data and ventricular pressure data and other data according to the blood pump calibration data to obtain final ventricular assist data. By setting the blood pump calibration data, the calculation accuracy of the ventricular assist data is improved, and the practicability of the system is improved.

[0142] Referring to FIGS. 6, 9 and 10, the first processing module 310 includes an interaction control module 311 and an interaction processor module 312; the interaction processor module 312, the interaction control module 311 and the second processing module 320 are sequentially stacked from top to bottom. The interaction processor module 312 is detachably connected with the interaction control module 311, and the interaction control module 311 is configured to control the interaction processor module 312 to control the interaction devices in the control device 2. The interaction processor module 312 includes a processor and a circuit board.

[0143] By dividing the interaction function and the control function of the work assembly and deploying them in two different processor modules respectively, the normal operation of each work assembly can be ensured in the case of interaction function downtime. Moreover, the first processing module responsible for the UI (interaction interface) is further divided into the detachably connected interaction processor module and the interaction control module, thereby facilitating the maintenance of the interaction processor module in the first processing module.

[0144] Referring to FIG. 10, the console 21 includes a front wall 211, a rear wall 212, a side wall (not shown in FIG. 10) and a bottom wall 214; the front wall 211 is configured to arrange at least one of the interaction devices, the rear wall 212 includes a stepped portion 2121, a back plate portion 2122 located above the front end of the stepped portion 2121 and an interface back plate 2123 located below the rear end of the stepped portion 2121; the front wall 211 is obliquely connected with the back plate portion 2122, and the back plate portion 2122, the front wall 211 and the side wall form a first accommodating space S1; the stepped portion 2121 is parallel to the bottom wall 214, and the front wall 211, the stepped portion 2121 and the interface back plate form a second accommodating space S2 with the bottom wall 214; the first accommodating space S1 is located on the side away from the bottom wall 214 of the second accommodating space S2. The interaction processor module 312, the interaction control module 311 and the second processing module 320 are sequentially stacked from top to bottom in the second accommodating space S2. By arranging the multi-layer stacked structure, the space utilization of the bottom space of the console 21 is optimized, the volume of the console is reduced, and the console is convenient to carry.

[0145] Referring to FIGS. 9 and 10, the console 21 further comprises a battery module 215, an AC / DC conversion module 216, and a heat dissipation module 217; the battery module 215 is disposed between the second processing module 320 and the bottom wall 214, the AC / DC conversion module 216 is arranged above the first accommodating space S1 of the interactive processor module 312, and the heat dissipation module 217 is arranged between the AC / DC conversion module 216 and the side wall. By optimizing the layout inside the console 21, arranging the heat dissipation module 217 above the main heat generating modules (such as the AC / DC conversion module 216 and the interactive processor module 312) is conducive to improving the heat dissipation effect.

[0146] Optionally, the surrounding wall surface of at least one of the first accommodating space S1 and the second accommodating space S2 is provided with a heat dissipation hole, and the first accommodating space S1 and the second accommodating space S2 are in communication with each other to form a heat dissipation channel.

[0150] In some embodiments, the above-mentioned console has a first state applied to an extracorporeal artificial heart, a second state applied to an interventional artificial heart, and a third state applied to an extracorporeal membrane oxygenation device; the console comprises an accommodating platform portion, which can be the above-mentioned stepped portion 2121.

[0151] In the first state, the accommodating platform portion is used to accommodate an extracorporeal blood pump, and the extracorporeal artificial heart comprises the blood pump; specifically, the extracorporeal blood pump can be supported on the above-mentioned accommodating platform portion by a support arm. The above-mentioned extracorporeal artificial heart can be an extracorporeal magnetic suspension blood pump.

Optionally, the extracorporeal membrane oxygenation device described above can further comprise the blood pump, and the blood pump and the oxygenator are connected through a pipeline. The blood pump is used for providing power for blood circulation, and the oxygenator is used for oxygenating blood. The blood pump and the oxygenator can be placed on the carrier frame, and the carrier frame can be placed on the accommodating platform part.

[0154] In this way, the console can be adapted to various life support devices, such as the extracorporeal artificial heart, the interventional artificial heart and the extracorporeal membrane oxygenation device described above, so as to improve the universal adaptability of the console and reduce the research and development cost.

[0155] In some embodiments, the pump system control module 40 is further configured to perform bubble detection based on a first frequency; set a bubble flag bit to a bubble present state identifier in a case where a bubble is detected; set the bubble flag bit to a bubble absent state identifier in a case where a first duration of no bubble detection reaches a second duration; and the control system is further configured to acquire the bubble flag bit based on a second frequency; trigger a bubble alarm information when the bubble flag bit is the bubble present state identifier, and stop triggering the bubble alarm information when the bubble flag bit is the bubble absent state identifier for a third duration. In this application, the bubble alarm information includes but is not limited to at least one of the following: sound and light or image alarm information emitted based on the display screen of the console 21, sound alarm information emitted based on the sound module 218, or remote alarm information emitted based on a terminal device.

[0156] In the embodiments of the present application, the bubble detection task and the bubble alarm task are two independent tasks. The bubble detection task is used to change the bubble state identifier, and the bubble alarm task is used to alarm according to the bubble state identifier. The sensor for bubble detection is usually an ultrasonic sensor. Once the bubble passes through the bubble sensor, the bubble sensor can change the bubble state identifier bit. However, the time for the bubble to pass through the sensor is very short. If the alarm is only triggered during the period when the sensor detects the bubble, the alarm time is short, and the bubble may flow into other positions and not be eliminated. This bubble may be ignored by the operator. Therefore, the bubble alarm task cancels the alarm after the bubble flag bit is in the bubble absent state for a certain time, which improves the safety of the bubble alarm. The time (third duration) can be the time for the bubble to circulate at least one circle in the pipeline.

[0157] Optionally, the first frequency can be set as 100 Hz, i.e., the bubble detection task is performed once every 10 milliseconds; and the second frequency can be set as 2 Hz, i.e., the bubble alarm triggering task is performed once every 500 milliseconds.

[0158] Specifically, the pump system control module 40 reads data of the bubble sensor based on the first frequency (e.g., 100 Hz) for detecting bubbles in the flush pipeline. During the execution of the bubble detection task, when the pump system control module 40 reads that the bubble sensor detects bubbles in the flush pipeline, the pump system control module 40 sets the bubble flag to the bubble presence state identifier; and when the pump system control module 40 reads that the bubble sensor does not detect bubbles and the first duration of no bubble detection reaches the second duration (e.g., 1 second), the pump system control module 40 sets the bubble flag to the bubble absence state identifier. During the execution of the bubble alarm triggering task, the control system of the present application reads the bubble flag based on the second frequency (e.g., 2 Hz), triggers the bubble alarm information when the bubble flag is the bubble presence state identifier, and stops triggering the bubble alarm information when the bubble flag is the bubble absence state identifier for a third duration (e.g., 5 seconds). By configuring the bubble detection and bubble alarm functions, the operator is timely and continuously reminded of the bubbles entering the flush pipeline, so as to avoid the bubbles entering the target object.

[0159] Optionally, the pump system control module 40 is further configured to: acquire flush pump operation data; and adjust at least one of the first frequency and the second frequency according to the flush pump operation data. The flush pump operation data includes but is not limited to the flush pump flow rate. Specifically, the bubble detection frequency can be adjusted according to the fluid dynamics of the flush fluid in the flush pump, for example, by increasing the first frequency to detect smaller bubbles of higher flow rate. By dynamically adjusting the bubble detection frequency, the detection accuracy is improved, the bubble missed detection is avoided, and the product safety performance is improved.

[0160] In some embodiments, the control device 2 is configured to: in the case that the bubble alarm information is cancelled, issue a bubble prompt information, the bubble prompt information being used to represent that the control device 2 has issued a bubble alarm, to indicate that bubbles have appeared in the fluid channel corresponding to the blood pump 1.

[0161] Optionally, the bubble prompt information can be displayed to the operator through the display screen of the console 21 or the sound module 218. Specifically, the case in which the above-mentioned bubble alarm information is cancelled can be the case in which the control device 2 stops triggering the bubble alarm information when the bubble flag bit is in the no-bubble state for a third time length (for example, 5 seconds). At this time, the control device 2 can issue the prompt information prompting the operator that the control device 2 has issued the bubble alarm. The duration of the bubble alarm is limited, but the flushing pipeline connected outside the blood pump is relatively long, and there is also a flushing flow channel inside the blood pump. The bubble can be trapped in a certain position in the pipeline or flow channel after passing through the bubble sensor, but it can also not be detected again by the bubble sensor in a short time because it is trapped. In the normal case in which the bubble can be eliminated, the bubble alarm cannot be continuously issued. Therefore, the above-mentioned bubble prompt information can remind the operator that the bubble has occurred in a recent period of time, so as to facilitate the operator to timely troubleshoot and eliminate the safety hazard that the bubble is trapped but not found, and improve the safety.

[0162] In addition, the control device 2 can also accumulate the number of times of issuing the bubble alarm to remind the operator that the bubble has occurred in the fluid passage corresponding to the blood pump 1, so as to avoid the operator forgetting and improve the practicability and safety of the product.

[0163] In some embodiments, the blood pump 1 is an interventional pump, the interventional pump includes an arterial pressure sensor, the interventional pump is connected with the control device 2 after the interventional pump is inserted into the target object, and the control system is configured to: acquire arterial pressure data detected by the arterial pressure sensor in the case where the interventional pump is connected with the blood pump driving device 221; and trigger an alarm information of long-time non-operation of the interventional pump if the blood pump 1 is not started within a fourth time length of detecting the arterial pressure data.

[0164] In the present application, referring to FIG. 2, the arterial pressure sensor can be arranged in an arterial pressure measurement passage formed by the gap between the interventional sheath and the driving catheter and the arterial pressure measurement tube.

[0165] Specifically, the intervention process of the intervention pump is to push the intervention pump until the over-arched transvalvular position, withdraw the guide wire, and tighten the proximal seal of the machine head, then fix the intervention sheath, lock the heavy repositioning sterile cover and the intervention sheath, and then connect the intervention pump arterial pressure line interface (outlet) with the intervention sheath side branch pipe three-way valve, at this time, the arterial pressure measurement condition is met, the gap between the intervention sheath and the catheter flows blood, the arterial pressure line interface communicates with the gap to form a fluid flow channel, and the blood pressure sensor on the other side of the arterial pressure line interface can thus detect the blood pressure. After the arterial pressure measurement condition is met, such as the intervention sheath is connected with the arterial pressure line interface of the driving catheter handle, the intervention pump can be connected with the control device 2, for example, the second electrical connector 10P arranged on one side of the intervention pump is plugged with the first electrical connector 20P arranged on one side of the control device 2, and the specific steps are to put the intervention pump driving catheter handle into the sterile bag, put the other end of the sterile bag into the driving motor and blood pump driving device, and chase the intervention pump driving catheter handle in the sterile bag, and connect the driving motor with the lock buckles on both sides of the intervention pump driving catheter handle. After the intervention pump is connected to the control device 2, the control device 2 can obtain the arterial pressure data detected by the arterial pressure sensor. In the normal case, after the intervention pump is connected with the control device 2, the driving motor should be started to drive the intervention pump to work. If the driving motor is not started for a long time after the intervention pump is connected with the control device 2, an abnormal situation may occur. Therefore, if the blood pump 1 is not started within the fourth time length (for example, 2 minutes) of detecting the arterial pressure data, an alarm information of long-time non-operation of the intervention pump is triggered. By acquiring the time length of arterial pressure detection, the alarm prompt of non-operation of the intervention pump is effectively triggered, which is convenient for indicating the operator to troubleshoot equipment errors or operation errors, and improves the safety performance of the equipment.
