Figure 1 As shown, the ventricular assist device of the present application includes a blood pump 1 and a control device 2, and the control device 2 is detachably connected to the blood pump 1.

During use, the interventional pump is percutaneously implanted into the heart through a peripheral blood vessel, with the pump head implanted between the left ventricle and the aorta. The blood inlet of the pump head is implanted into the left ventricle, and the blood outlet of the pump head is implanted into the aorta, thereby pumping blood from the left ventricle into the aorta to achieve ventricular assist function.

[0074] Optionally, the blood pump 1 is also connected to a flushing circuit. The drive device 22 is also used to drive the flushing fluid in the flushing circuit to vent and flush the internal gaps of the interventional pump, thereby preventing blood from entering the interventional pump catheter and forming thrombi, and preventing air from entering the subject's body through the internal gaps of the interventional pump and forming air emboli.

The gap between the interventional sheath 12 and the driving catheter 13 is connected to the arterial pressure measuring tube to form an arterial pressure measuring path.

[0077] See also Figure 2As shown, the drive device 22 includes an infusion pump and a circulation pump. The infusion pump is used to drive the flushing line 14, pumping the flushing fluid in the flushing line into the gap within the blood pump 1 to prevent air bubbles from entering the human body and prevent blood from flowing back into the drive catheter 13. The circulation pump is used to drive the flushing fluid to circulate along the circulation line to cool the flushing fluid.

This ventricular assist prediction model uses the blood pump sensor data and / or blood pump drive data as input, simulates and calculates ventricular assist data, and outputs it. The ventricular assist prediction model can be optimized through training with a large amount of input and output data. During the use of the device, the blood pump sensor data and / or blood pump drive data actually collected by the blood pump monitoring module 10 and the motor monitoring module 20 are imported into the trained ventricular assist model, and the above-mentioned ventricular assist data are predicted and output, so that the user can view the difficult-to-detect ventricular assist parameters, such as the above-mentioned intervention position, blood pump flow, ventricular pressure, etc.

[0082] The console control module 30 is connected to the pump system control module 40 and is responsible for handling human-computer interaction and system control operations for the control device 2. Human-computer interaction operations include, but are not limited to: providing a simple and intuitive user interface that displays at least one of blood pump sensor data, blood pump drive data, or ventricular assist data; configuring or modifying the speed of the blood pump 1; configuring or modifying alarm thresholds and system parameters; providing alarms of varying levels, automatically recording each alarm message, and displaying relevant charts in summary reports. System control operations include, but are not limited to, operations related to the working equipment of the control device 2, such as forwarding control commands.

[0083] In the present application, the control functions of the control system are mainly set 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 the data monitoring function, forming a control system based on the external motor coupling 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 receiving the data returned by the blood pump monitoring module 10 and the motor monitoring module 20, namely the blood pump sensor data and the blood pump drive data, importing the blood pump sensor data and / or the blood pump drive data into the trained ventricular assist model, calculating the ventricular assist data, such as the intervention position data, the blood pump flow data and the ventricular pressure data, and sending at least one of the blood pump sensor data, the blood pump drive data or the ventricular assist data to the console control module 30 for display via the console 21. By setting the control function in the external control device and non-consumable parts, calculating the ventricular assist data in the external control module (pump system control module 40), providing a reference basis for the blood pump operation, and retaining some necessary monitoring functions on the blood pump side, the number of electronic components and structural complexity in the blood pump consumables can be effectively reduced, the processing cost and material cost of the blood pump are reduced, the structure of the blood pump consumables is simplified, and the problems of complex structure and high loss cost of the blood pump consumables in related technologies are solved, thereby reducing the cost of product use.

[0084] In addition, in the control system, the console control module is used to realize the human-computer interaction operation and system control operation of the control device, meeting the user's interactive operation requirements for the ventricular assist device; the motor monitoring module is used to monitor the blood pump drive data, and the pump system control module can control the operation of the blood pump. Such a design can separate the control module and the monitoring module of the blood pump. When either one is damaged or abnormal, it can be independently maintained and replaced, reducing maintenance costs; and the pump system control module is connected to the blood pump monitoring module through the motor monitoring module, and can determine the ventricular assist data corresponding to the blood pump based on the blood pump sensor data and / or blood pump drive data, and calculate the ventricular assist data through the pump system control module external to the blood pump, providing reliable reference data for the blood pump operator.

[0085] Figure 4 This is a schematic diagram of the structure of another ventricular assist device provided in an embodiment of the present application. Figure 4 As shown, the control device 2 includes a console 21, a blood pump driving device 221 and a flushing pump driving device 222; the console 21 and the blood pump driving device 221 are connected via a first connecting line 223, and the flushing pump driving device 222 is mounted on the console 21. The blood pump driving device 221 is coupled to the blood pump 1

[0086] The driving device 22 may include the blood pump driving device 221 and the flushing pump driving device 222 .

[0087] Optionally, the length of the first connecting line 223 satisfies the distance requirement between the equipment operation area and the blood pump operation area. The equipment operation area refers to the area in the surgical space where the console 21 and the flushing pump drive device 222 are placed, such as the area outside the operating table, the area where the equipment is placed on the table, or the area where the trolley is located. The blood pump operation area refers to the sterile surgical area in the surgical space where the blood pump 1 is operated to perform an interventional procedure on the target subject, such as the operating table.

[0088] It should be noted that the embodiment of the present application does not limit the length of the first connecting line, which can be determined according to the actual product usage scenario.

[0089] Optionally, the blood pump driving device 221 includes but is not limited to a driving motor.

[0090] See also Figure 4 As shown, the blood pump drive device 221 is connected to the blood pump 1. The blood pump monitoring module 10 is installed in the drive catheter handle 11 of the blood pump 1, and the drive catheter handle 11 is pluggable with the blood pump drive device 221. When the ventricular assist device is in working condition, the blood pump drive device 221 is coupled to the drive catheter handle 11, and the blood pump drive device 221 drives the impeller in the pump head to rotate. The rotation speed of the blood pump drive device 221 can be set through the interactive device of the console 21 (such as a knob, button or display screen). When the ventricular assist device is in non-working condition, the blood pump drive device 221 is disconnected from the drive catheter handle 11 of the blood pump 1. Optionally, in the non-working condition, the blood pump drive device 221 and the first connecting line 223 can be stored in the console 21, or stored in an independently provided storage device.

[0091] Figure 5 This is a schematic diagram of the structure of a control system of another ventricular assist device provided in an embodiment of the present application. Figure 5 As shown, the motor monitoring module 20 is arranged in the blood pump drive device 221. During use, the pump system control module 40 can detect whether the blood pump drive device 221 has abnormal operation based on the blood pump drive data of the motor monitoring module 20, such as the motor temperature is too high or the motor speed is abnormal or the current is too large. The pump system control module 40 can then send an abnormal alarm signal of the blood pump drive device 221 to the console 21; wherein, the pump system control module 40 is arranged in the flushing pump drive device 222; the console control module 30 is arranged in the console 21.

[0092] The pump system control module 40 is at least used to control the operation of the blood pump driver 221 to drive the blood pump. In the ventricular assist device, in addition to the fact that the blood pump is a consumable part, the blood pump driver 221 needs to rotate stably at high speed (up to tens of thousands of revolutions), and has high quality requirements, so it is a consumable component. Once the jitter generated by the blood pump driver 221 exceeds the acceptable range, even if it can still operate, it needs to be replaced with a new blood pump driver 221. Figure 4 Taking the ventricular assist device shown in the figure as an example, the flush pump drive unit 222 is fixedly mounted on the console 21, and the wear and tear of both is relatively low. Compared with the flush pump drive unit 222 and the console 21, the blood pump drive unit 221 is equipped with a drive motor, which needs to rotate at high speed and stably to maintain a high blood pumping volume. If the drive unit of the drive motor is installed in the blood pump drive unit 221, the motor may malfunction while the drive unit is still normal. However, if the drive unit is installed in the blood pump drive unit 221, the entire blood pump drive unit 221 needs to be replaced. Therefore, in the embodiment of the present application, the pump system control module 40 provided inside the flushing pump driver 222 controls the operation of the blood pump driver 221. When the blood pump driver 221 suffers losses (motor shaking, motor damage, etc.), the waste of related drive units of the blood pump driver 221, such as the motor drive unit, can be reduced. Only the blood pump driver 221 with a simple structure needs to be replaced. This effectively reduces the number of electronic devices and the complexity of the circuit modules inside the blood pump driver 221, a consumable component, simplifies the internal structure of the blood pump driver 221, reduces the cost of the blood pump driver 221, and further reduces the cost of using the product.

[0093] In summary, the technical solution provided in the embodiments of the present application not only simplifies the structure of blood pump consumables, but also simplifies the structure of consumable equipment, thereby reducing the overall cost of consumables and consumable equipment in the ventricular assist device and further reducing the cost of using ventricular assist device products.

[0094] See also Figure 5 As shown, the control device 2 also includes a flushing pump 224, which is connected to the flushing pump driving device 222. The pump system control module 40 is also used to control the operation of the flushing pump 224. Specifically, the flushing pump 224 can be a peristaltic pump, which can realize the flushing fluid delivery and control functions by squeezing the flushing pipeline to prevent blood from entering the driving catheter 13 (see Figure 2 ) produces thrombus.

[0095] Optionally, the flushing pump driving device 222 is provided with the above-mentioned flushing pump 224 .

[0096] Optionally, the console 21 and the pump system control module 40 may be connected via CAN communication, the pump system control module 40 and the motor monitoring module 20 may be connected via RS485 communication, and the blood pump driver 221 and the blood pump monitoring module 10 may be connected via serial communication. Optionally, the serial communication may be a 3.3V serial communication.

[0097] Figure 6 A structural diagram of a control system of another ventricular assist device provided in an embodiment of the present application is a schematic diagram showing, by way of example, the internal structure and connection relationship of each module in a control system.

[0098] See also Figure 6 As shown, the motor monitoring module 20 includes a first controller unit 201 and a communication interface module 202 , and the communication interface module 202 is used 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 .

[0099] Alternatively, see Figure 6 As shown, the motor monitoring module 20 also includes a first storage unit 205 connected to the first controller unit 201. The first controller unit 201 is also used to obtain the motor operating time. The first storage unit 205 is used to store the motor operating time. Specifically, the first storage unit 205 is used to record the cumulative operating time of the drive motor 225. Because the drive motor in the blood pump drive device has a service life and needs to be replaced after reaching a set service life, the device also needs to record the cumulative operating time of the drive motor. However, although the blood pump drive device and the flushing pump drive device are used in conjunction, the two are detachably connected. The flushing pump drive device does not drive only one blood pump drive device. If the flushing pump drive device stores the cumulative operating time of each connected blood pump drive device, the data structure of the flushing pump drive device will increase in complexity and may store a lot of useless data, wasting storage space. By having the blood pump drive device store its own cumulative operating time, the flushing pump drive device or the control console does not need to store the accumulated operating time, and there is no need to distinguish the accumulated operating time of different blood pump drives. When the motor operation time exceeds the set time, the console can issue a motor replacement prompt to remind the operator to replace the motor, thereby improving the operation reliability of the drive motor 225.

[0100] Preferably, see Figure 6As shown, the motor monitoring module 20 further includes: a temperature detection unit 206 and / or a speed detection unit 207 connected to the first controller unit 201. The temperature detection unit 206 is used to obtain the motor temperature (for example, the coil temperature of the drive motor 225), and the speed detection unit 207 is used to obtain the motor speed. By reading the motor temperature and / or the motor speed, or identifying the motor operating condition based on the motor temperature and / or the motor speed, the console can trigger a motor abnormality alarm when the motor temperature exceeds a first temperature range or the motor speed exceeds a first speed range.

[0101] See also Figure 6 As shown, the blood pump monitoring module 10 includes: a second controller unit 101, and a second storage unit 102 and a sensor detection unit 103, respectively connected to the second controller unit 101; the second storage unit 102 is used to store blood pump calibration data, and the sensor detection unit 103 includes at least one of the following: an irrigation pressure sensor 104, an arterial pressure sensor 105, and an ambient pressure sensor 106; the second controller unit 101 is communicatively connected to the pump system control module 40. Specifically, the communication channel between the second controller unit 101 and the pump system control module 40 is provided in the motor monitoring module 20. By providing the above-mentioned main circuit modules in the blood pump monitoring module, the structure of the blood pump monitoring module can be simplified while meeting the basic data monitoring requirements of the ventricular assist device, reducing the size of the drive catheter handle, making it easier to hold, and reducing costs.

[0102] See also Figure 6 As shown, the control device 2 includes a flushing pump 224 and a drive motor 225. The drive motor 225 is used to drive the blood pump 1 to operate, and the flushing pump 224 is used to drive the flushing fluid in the blood pump 1. Typically, the flushing pump 224 includes but is not limited to an infusion pump and a circulation pump. Figure 6 As shown, the pump system control module 40 includes at least: a flushing pump drive unit 402, which is used to drive the flushing pump 224 to operate; a flushing pump monitoring unit 403, which is used to obtain flushing pump operation data; a motor drive unit 404, which is used to drive the drive motor 225 to operate; a drive monitoring unit 405, which is used to obtain the drive unit operation data of the motor drive unit 404 and the flushing pump drive unit 402; and a third controller unit 401, which is connected to the flushing pump drive unit 402, the flushing pump monitoring unit 403, the motor drive unit 404 and the drive monitoring unit 405.

[0103] By arranging the flushing pump drive unit, flushing pump monitoring unit, motor drive unit and drive monitoring unit in the pump system control module and in the flushing pump drive device, there is no need to arrange the motor drive unit and drive monitoring unit in the blood pump drive device, thereby simplifying the structure of the blood pump drive device and reducing the cost of the blood pump drive device.

[0104] Optionally, the pump system control module 40 further includes at least one of the following: 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 to the third controller unit 401 and is configured to obtain bubble detection data from the flushing pipeline and transmit the bubble detection data to the third controller unit 401. The third storage unit 407 is connected to the third controller unit 401 and is configured to receive and store at least one of the following: bubble detection data, flushing pump operation data, and drive unit operation data. By incorporating the bubble detection unit into the pump system control module, the bubble detection unit can be effectively reused, eliminating the need to incorporate it into the consumables portion of the blood pump.

[0105] The first end of the third communication interface chip 408 is communicatively connected to the third controller unit 401. The second end of the third communication interface chip 408 is communicatively connected to the communication interface module 202 of the motor monitoring module 20. The third communication interface chip 408 is also communicatively connected to the communication interface module of the blood pump monitoring module. This third communication interface chip comprises the communication chip in the pump system control module, which can be one or more. The pump system control module serves as an embedded real-time control platform and a communication host, controlling and managing the two slave devices, the blood pump driver and the blood pump. It periodically sends messages to the blood pump driver and the blood pump. The message content includes control messages sent by the communication host and status messages returned by the slave devices. The blood pump monitoring module and the motor monitoring module are two parallel slave devices. Although the flushing pump drive device, blood pump drive device, and blood pump are connected in sequence, the pump system control module still communicates directly with the blood pump monitoring module. 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 drive device is abnormal or the motor monitoring module is working abnormally, it does not affect the communication between the pump system control module and the blood pump monitoring module, ensuring the normal transmission of blood pump monitoring data.

[0106] The input end of the power supply unit 409 is electrically connected to the power management module 323 provided in the console control module 30. The first output end of the power supply unit 409 is electrically connected to the power supply end of the third controller unit 401. The second output end of the power supply unit 409 is electrically connected to the power supply end of the blood pump monitoring module 10 via the power isolation unit (i.e., the third isolation unit 210) provided in the motor monitoring module 20. Preferably, the third communication interface chip 408 is an RS485 interface chip. Similarly, when the flushing pump drive device, blood pump drive device, and blood pump are connected in sequence, the pump system control module still directly supplies power to the blood pump monitoring module. The power 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 power supply. When the blood pump drive device or the motor monitoring module malfunctions, it does not affect the communication between the pump system control module and the blood pump monitoring module, thus ensuring the normal transmission of blood pump monitoring data. In addition, the power supply connection line between the pump system control module and the blood pump monitoring module is provided with an isolation unit to provide power supply isolation for the blood pump, thereby ensuring the safety of the target object when the blood pump intervenes in the target object's body and preventing abnormal electrical signals from affecting the life safety of the target object.

[0107] See also Figure 6 As shown, the motor monitoring module 20 includes multiple communication channels, and the multiple communication channels include a first communication channel I and a second communication channel II; wherein, the first communication channel I is used to communicate with the pump system control module 40 and the motor monitoring module 20; the second communication channel II is used to communicate with 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 to provide electrical isolation between the blood pump monitoring module 10 and the pump system control module 40.

[0108] The pump system control module serves as an embedded real-time control platform and a communication host. It controls and manages the two slave devices, the motor monitoring module and the blood pump monitoring module, through two parallel communication channels within the motor monitoring module, thereby periodically sending messages to the blood pump driver and the blood pump. The blood pump monitoring module and the motor monitoring module are two parallel slave devices. Although the flushing pump driver, the blood pump driver, and the blood pump are connected in sequence, by providing two communication channels within the motor monitoring module, the pump system control module can still communicate directly with the blood pump monitoring module. The communication connection between the pump system control module and the blood pump monitoring module passes through the motor monitoring module, which improves the stability of system communication. When the blood pump driver or the motor monitoring module malfunctions, it does not affect the communication between the pump system control module and the blood pump monitoring module, ensuring the normal transmission of blood pump monitoring data.

[0109] Furthermore, because some sensors within the blood pump monitor blood pressure, they communicate with the subject's blood fluid during insertion, forming a conductive channel. An isolation unit is installed in the communication channel between the pump system control module and the blood pump monitoring module to isolate the blood pump's power supply. This ensures the subject's safety while the blood pump is operating, preventing any potential hazards from anomalous electrical signals.

[0110] See also Figure 6 As shown, the multiple communication channels also include a third communication channel III, which is used to establish a communication connection between the blood pump monitoring module 10 and the motor monitoring module 20. The third communication channel III is provided with a second isolation unit 209, which is used to provide electrical isolation between the blood pump monitoring module 10 and the motor monitoring module 20.

[0111] In some embodiments, the blood pump monitoring module 10 is communicatively connected to the motor monitoring module 20, and the blood pump monitoring module detects whether the blood pump is in place by detecting the communication signal. In this case, a second isolation unit is provided between the blood pump monitoring module and the motor monitoring module 20, thereby providing electrical isolation between the two, so as to ensure the safety of the target object when the blood pump intervenes in the target object's body and prevent abnormal electrical signals from affecting the life safety of the target object.

[0112] Specifically, the first communication channel I and the second communication channel II can be RS485 communication channels, the third communication channel III can be a serial communication channel, the first isolation unit 208 and the second isolation unit 209 include at least communication isolation elements, and by setting communication isolation elements on the second communication channel II and the third communication channel III, an isolated communication signal is provided to one side of the blood pump 1, which can improve the communication protection level on the intervention side.

[0113] See also Figure 6 As shown, the motor monitoring module 20 also includes a power supply channel IV, which is used to connect the pump system control module 40 and the blood pump monitoring module 10 with power. The power supply channel IV is provided with a third isolation unit 210, which is used to provide secondary electrical isolation between the pump system control module 40 and the blood pump monitoring module 10. Similarly, because some sensors within the blood pump need to detect blood pressure, when the blood pump is inserted into the body, it will communicate with the blood fluid in the target subject's body, forming a conductive channel. An isolation unit is provided on the communication channel between the pump system control module and the blood pump monitoring module to provide power isolation for the blood pump, thereby ensuring the safety of the target subject when the blood pump is inserted into the target subject's body and preventing abnormal electrical signals from affecting the target subject's life safety.

[0114] In some embodiments, the console control module 30 is provided with a fourth isolation unit 301, and the fourth isolation unit 301 is used to provide a first level of electrical isolation between the input power supply and the console control module 30. Preferably, the control device 2 includes an AC / DC conversion module, the console control module 30 is connected to the AC power supply through the AC / DC conversion module, and the fourth isolation unit is provided in the AC / DC conversion module. Specifically, the fourth isolation unit 301 performs voltage conversion and first level 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 via the third isolation unit 210. The fourth isolation unit 301 and the third isolation unit 210 form a two-level power supply isolation structure, which can improve the power supply protection level on the intervention side, reduce the leakage risk on the intervention side, and improve the product safety performance.

[0115] Figure 7 This is a schematic diagram of the structure of a motor monitoring module provided in an embodiment of the present application. Figure 6 and Figure 7 As shown, 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 connected, and the first electrical connector 20P has better wear resistance than 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 channel of the motor monitoring module 20, and the second electrical connector 10P is used to connect the communication channels and / or the power supply channel of the blood pump monitoring module 10. When the first electrical connector 20P and the second electrical connector 10P are plugged together, the power supply circuit and the communication circuit between the blood pump monitoring module 10 and the motor monitoring module 20 are connected. In this embodiment, the first electrical connector 20P and the second electrical connector 10P can be spring pin connectors, that is, the spring pin connectors are 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 spring connector, and the second electrical connector 10P is a male spring connector. Because the male spring connector is more fragile than the female spring connector, the male spring connector is placed on the side of the blood pump 1 (i.e., the consumable), and the motor monitoring module is located on the blood pump drive device. This is reused, with the more fragile male spring connector placed on the consumable side and the less fragile female spring connector placed on the non-consumable side. This improves the quality and reliability of the non-consumable side and enhances the communication stability of the system.

[0116] In some embodiments, the motor monitoring module 20 is also used to: determine the blood pump in-place detection result based on 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 the blood pump in-place and the blood pump not in-place, the blood pump in-place indicates that the blood pump 1 is successfully connected to the control device 2; the blood pump not in-place indicates that the blood pump 1 is not successfully connected to the control device 2. In the related art, a separate in-place detection pin is required to perform in-place detection of the blood pump, while in the embodiment of the present application, the motor monitoring module reuses the communication signal to perform in-place detection of the blood pump, reducing the in-place detection pin and reducing the product size. Specifically, the blood pump drive device 221 and the blood pump 1 both need to be held by the operator when in use, such as Figure 4 As shown, since the blood pump drive device 221 and the blood pump 1 are respectively provided with mutually coupled rotary drive components at the axial center, the connector between the two needs to be set in the annular gap between the rotary drive component and the outer peripheral side wall. Reducing one in-situ detection pin can effectively reduce the size of the annular gap, thereby reducing the diameter of the blood pump drive device 221 and the drive catheter handle 11, making it easier for the operator to hold, thereby improving the convenience of operation.

[0117] Specifically, see Figure 6 and Figure 7 As shown, the communication signal between the motor monitoring module 20 and the blood pump monitoring module 10 is a 3.3V serial communication signal. Therefore, the presence of the blood pump 1 can be detected by detecting the level 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, the blood pump is determined to be in place, i.e., the blood pump 1 is successfully connected to 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, the blood pump is determined to be not in place, i.e., the blood pump 1 is not successfully connected to the control device 2. By detecting the connection status 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 presence detection function can be realized. There is no need to add a dedicated detection pin to perform blood pump presence detection, which reduces the number of connection pins between the motor monitoring module and the blood pump monitoring module, can reduce the insertion and fitting cross-sectional length between the blood pump and the control device, reduce the total volume of the blood pump, and reduce the difficulty of insertion and fitting alignment.

[0118] Optionally, Figure 8 This is a schematic diagram of the circuit connection structure of a motor monitoring module provided in an embodiment of the present application. Figure 8As shown, the first communication pin pin1 of the blood pump monitoring module 10 is connected to the second communication pin pin2 of the motor monitoring module 20, and periodic serial communication is adopted between the motor monitoring module 20 and the blood pump monitoring module 10; the motor monitoring module 20 is configured to: obtain the communication signal corresponding to the second communication pin and the first duration of the communication signal in the first state; determine the in-situ detection result according to the signal state and the first duration of the communication signal.

[0119] Preferably, the present application adopts a low level to indicate that it is not in place, and a high level to indicate that it is in place. 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 place. After the motor monitoring module 20 is connected to the blood pump monitoring module 10, 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 connection between the motor monitoring module 20 and the blood pump monitoring module 10 is completed, 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 and low, and it is no longer appropriate to continue to use high and low levels as in-place detection. To account for the situation where the serial port transmits TX signals at varying levels during communication, and considering the case where the serial port is high in the idle state, the presence check condition is modified from detecting high and low levels to detecting whether the low level persists for a certain period of time (the detection time is set according to the communication cycle). This allows accurate and reliable detection of the interventional pump's presence when it is disconnected, connected, or reconnected after a disconnection. Therefore, by combining the communication signal state and the duration of the communication signal's first state for presence detection, both communication and presence detection functions are implemented.

[0120] See also Figure 7 and Figure 8As shown, the motor monitoring module 20 includes 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 to the communication interface module 202 and the first controller unit 201, respectively. The second communication pin PIN2 of the motor monitoring module 20 is connected to the communication interface module 202 and the first controller unit 201, respectively. In this embodiment, the communication signal is a communication transmission signal (such as the TX signal described above). Optionally, the first communication pin PIN1 and the second communication pin PIN2 are communication transmission pins. The first communication pin is connected to the power supply VDD via a pull-up resistor R10; the second communication pin PIN2 is connected to ground via a pull-down resistor R20; the first state includes at least a low-level state; the motor monitoring module 20 is configured to determine that the blood pump is not in place when the first state is a low-level state and the first duration of the low-level state is greater than the first duration. Preferably, the power supply VDD can be used to provide a 3.3V DC supply voltage. The resistance value of the pull-up resistor R10 can be smaller than the resistance value of the pull-down resistor R20. In this embodiment, the first duration is set according to the communication cycle between the blood pump monitoring module 10 and the motor monitoring module 20. Preferably, the first duration can be set to 100 milliseconds.

[0121] Specifically, see Figure 8As shown, the communication transmission pin (i.e., first communication pin 1) of the blood pump monitoring module 10 is connected to both the second communication interface chip 204 and the second communication pin 2 of the first controller unit 201 on the circuit board of the motor monitoring module 20. Periodic serial communication is used between the first communication pin 1 and the second communication pin 2. The first controller unit 201 detects the signal state of the second communication pin 2 in real time. Before the blood pump 1 is connected to the control device 2, the second communication pin 2 is pulled down to a low level by the pull-down resistor R20. At this time, the signal state of the communication transmission signal detected by the first controller unit 201 is low, and the blood pump is determined to be out of position. When the blood pump 1 is connected to the control device 2, the first communication pin 1 is pulled up to a high level by the pull-up resistor R10. At this time, the signal state of the communication transmission signal detected by the first controller unit 201 is high, and the blood pump is determined to be in position. After the blood pump 1 and the control device 2 begin periodic communication, the signal state of the communication transmission signal detected by the first controller unit 201 is high or low, and the communication transmission signal is in a high-level state in the idle state. If the signal state of the communication transmission signal detected by the first controller unit 201 is a low-level state, and the first duration in the low-level state is greater than the first duration (for example, 100 milliseconds), the blood pump is determined to be out of position; if the signal state of the communication transmission signal detected by the first controller unit 201 is a high-level state, or the first duration in the low-level state is less than or equal to the first duration (for example, 100 milliseconds), the blood pump is determined to be in position. By setting pull-up resistors and pull-down resistors, the reliability of the signal detection result is improved. In-position detection is performed using the idle period of communication, that is, the signal state and duration of the communication signal in the idle state of the serial communication, so that blood pump in-position detection can be achieved in different scenarios such as blood pump not connected, connection completed, and reconnection after connection completed, without adding additional detection pins, simplifying the structure and being easy to use.

[0122] Preferably, see Figure 8 As shown, the communication interface module 202 includes 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 to the pump system control module 40, and the second end of the first communication interface chip 203 is connected to the first controller unit 201. The first communication interface chip 203 is set in the first communication channel I; the first end of the second communication interface chip 204 is connected to the pump system control module 40, and the second end of the second communication interface chip 204 is connected to the blood pump monitoring module 10 via the first isolation unit 208. The second communication interface chip 204 and the first isolation unit 208 are set in the second communication channel II. Figure 8As shown, the third controller unit 401 of the pump system control module 40 is communicatively connected to the motor monitoring module 20 via the third communication interface chip 408 (e.g., an RS485 interface chip) and the first communication interface chip 203 (e.g., an RS485 interface chip). The third controller unit 401 is also communicatively connected to the blood pump monitoring module 10 via the third communication interface chip 408 (e.g., an RS485 interface chip), the second communication interface chip 204 (e.g., an RS485 interface chip), and the first isolation unit 208. The RS485 interface chip (i.e., the second communication interface chip 204) of the blood pump monitoring module 10 is disposed on the circuit board of the motor monitoring module 20.

[0123] In some embodiments, the blood pump monitoring module 10 is configured to store blood pump calibration data. The blood pump calibration data represents the operating characteristics of target components within the blood pump 1. The target components in this application include, but are not limited to, the irrigation pressure sensor 104, the arterial pressure sensor 105, the ambient pressure sensor, and the pump head. Optionally, the blood pump calibration data includes at least one of the following: hydraulic characteristic data and sensor characteristic data of the blood pump 1. The hydraulic characteristic data represents the fluid dynamic parameters and performance indicators of the target component during operation of the blood pump 1. Different pump heads, while having the same structural design, may have slight differences in production processes or assembly, resulting in slight variations in the hydraulic performance of each blood pump. The hydraulic characteristic data may include coefficients related to hydraulic performance indicators, such as flow rate and pressure differential, to facilitate calibration of ventricular assist data, such as flow rate, intervention location, and pressure. The sensor characteristic data represents the physical characteristics of the sensor, including, but not limited to, temperature coefficients, pressure coefficients, and humidity coefficients related to the measured values. It should be noted that the blood pump calibration data for each blood pump is different. Those skilled in the art can obtain and store the blood pump calibration data for each blood pump 1 through testing and calibration.

[0124] Accordingly, the pump system control module 40 of the present application is configured to determine ventricular assist data based on the blood pump calibration data and the blood pump sensor data and / or the blood pump drive data. Figure 6As shown, 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 accesses the blood pump calibration data (such as the hydraulic and sensor characteristics of the blood pump 1) stored in the second storage unit 102 via the second communication channel II. It also accesses the blood pump sensor data (such as irrigation pressure data, arterial pressure data, and ambient pressure data) collected by the blood pump monitoring module 10 via the second communication channel II. The pump system control module 40 also accesses the blood pump drive data (such as motor operating time, motor speed, and motor temperature) collected by the motor monitoring module 20 via the first communication channel I. The pump system control module 40 imports the blood pump sensor data and / or blood pump drive data collected by the blood pump monitoring module 10 and the motor monitoring module 20 into a pre-trained ventricular assist model to calculate ventricular assist data. The pump system control module 40 then optimizes and calibrates the intervention position data, blood pump flow data, and ventricular pressure data based on the blood pump calibration data to obtain the final ventricular assist data. By setting the blood pump calibration data, the calculation accuracy of the ventricular assist data is improved, thereby enhancing the practicality of the system.

Optionally, the working device includes at least one of the following: a sensor, an AC / DC converter module, a battery module, a motor, and a heat dissipation device (e.g., a fan). The motor may be a blood pump motor.

[0128] See also Figure 6 、 Figure 9 and Figure 10As shown, the first processing module 310 includes an interactive control module 311 and an interactive processor module 312; the interactive processor module 312, the interactive control module 311 and the second processing module 320 are stacked in order from top to bottom. The interactive processor module 312 is detachably connected to the interactive control module 311. The interactive processor module includes a processor for processing human-computer interaction operations. The interactive control module is connected to the interactive device. The interactive control module 311 is used to enable the interactive processor module 312 to control the above-mentioned interactive device. Among them, the interactive processor module 312 includes a processor and a circuit board. Optionally, see Figure 6 As shown, the interactive control module 311 is provided with a power management module, and the interactive control module 311 is also used to manage the power supply of the interactive processor module 312. Figure 6 As shown, the second processing module 320 includes a fourth controller unit 321 , a signal processing module 322 and a power management module 323 . The signal processing module 322 is used to perform signal conditioning on the sensor data and transmit the conditioned data to the fourth controller unit 321 .

[0129] By dividing the interaction functionality and the control functions of the working components and deploying them in two different processor modules, the normal operation of the working components can be ensured even if the interaction functionality fails. In addition, the first processing module responsible for the UI is divided into a detachable interaction processor module and an interaction control module, which facilitates maintenance of the interaction processor module in the first processing module.

[0130] See also Figure 10 As shown, the console 21 includes: a front wall 211, a rear wall 212, and side walls ( Figure 10 The front wall 211 is used to accommodate at least one of the interactive devices, and the rear wall 212 includes a step portion 2121, a back panel portion 2122 located above the front end of the step portion 2121, and an interface back panel 2123 located below the rear end of the step portion 2121. The front wall 211 and the back panel portion 2122 are connected at an angle, and a first accommodation space S1 is formed between the back panel portion 2122, the front wall 211, and the side walls. The step portion 2121 is arranged parallel to the bottom wall 214, and a second accommodation space S2 is formed between the front wall 211, the step portion 2121, the interface back panel, and the bottom wall 214. The first accommodation space S1 is located on the side of the second accommodation space S2 away from the bottom wall 214. The interactive processor module 312, the interactive control module 311, and the second processing module 320 are stacked in sequence from top to bottom in the second accommodation space S2. By setting up a multi-layer stacking structure, the space utilization rate of the bottom space of the console 21 is optimized, and a whole first accommodating space is reserved for accommodating other components, thereby reducing the volume of the console and making it easier to carry.

[0131] See also Figure 9 and Figure 10 As shown, the console 21 also includes a battery module 215, an AC / DC converter module 216, and a heat dissipation module 217. The battery module 215 is positioned between the second processing module 320 and the bottom wall 214, the AC / DC converter module 216 is located in the first accommodation space S1 above the interactive processor module 312, and the heat dissipation module 217 is located between the AC / DC converter module 216 and the side wall. By optimizing the internal layout of the console 21, the heat dissipation module 217 is positioned around the modules that generate the most heat (such as the AC / DC converter module 216 and the interactive processor module 312), which helps improve heat dissipation.

[0132] Optionally, heat dissipation holes are provided on the surrounding walls of at least one of the first accommodating space S1 and the second accommodating space S2, interconnecting the first accommodating space S1 and the second accommodating space S2 to form a heat dissipation channel. Providing heat dissipation holes in the first accommodating space S1 or the second accommodating space S2 forms a heat dissipation channel between the upper and lower accommodating spaces, thereby improving the heat dissipation within the console 21.

[0133] Optionally, the side wall includes a first side wall, and the first side wall is provided with a first through hole corresponding to the heat dissipation module 217. The heat dissipation effect is improved by opening the side wall.

[0134] Optionally, the console 21 also includes a sound module 218, which is arranged between the AC / DC conversion module 216 and the second side wall of the console 21. The second side wall of the console 21 is provided with a second through hole corresponding to the sound module 218, and a first heat dissipation channel is formed between the first through hole and the second through hole.

[0135] Optionally, the interface back panel of the console 21 is provided with a cable interface, and a second heat dissipation channel is formed between the cable interface and the first through hole. The side wall openings and the cable interface form multiple heat dissipation channels, thereby improving the heat dissipation effect of the console 21, preventing high temperature damage to the components inside the console, and extending the service life.

[0136] In some embodiments, the console has a first state for application to an extracorporeal artificial heart, a second state for application to an invasive artificial heart, and a third state for application to an extracorporeal membrane oxygenation device; the console includes a receiving platform portion, which may be the step portion 2121 .

[0137] In the first state, the accommodating platform is used to accommodate an extracorporeal blood pump, and the extracorporeal artificial heart includes a blood pump. Specifically, the extracorporeal blood pump can be supported on the accommodating platform by the support arms. The extracorporeal artificial heart can be an extracorporeal magnetic levitation blood pump.

[0138] In the second state, the accommodating platform portion is used to accommodate the flushing pump, and the interventional artificial heart includes a flushing pump (i.e., the above-mentioned flushing pump driving device); the bottom of the housing of the flushing pump driving device can be placed on the above-mentioned accommodating platform portion, and the inclined back panel of the housing of the flushing pump can be connected to the above-mentioned inclined back panel portion 2122, thereby adapting to the rear wall structure of the console.

[0139] In the third state, the accommodating platform is used to accommodate an oxygenator, and the extracorporeal membrane oxygenation device includes an oxygenator. Optionally, the extracorporeal membrane oxygenation device may further include the blood pump, which is connected to the oxygenator via a pipeline. The blood pump is used to provide power for blood circulation, and the oxygenator is used to oxygenate the blood. The blood pump and oxygenator can be placed on a supporting frame, and the supporting frame can be placed on the accommodating platform.

[0140] With this design, the console can be adapted to a variety of life support equipment, such as the aforementioned extracorporeal artificial heart, interventional artificial heart, and extracorporeal membrane oxygenation device, thereby improving the universal adaptability of the console and reducing R&D costs.

[0141] In some embodiments, the pump system control module 40 is further configured to: perform bubble detection based on a first frequency; if bubbles are detected, set the bubble flag to a bubble state indicator; if no bubbles are detected for a second duration reaching a second duration, set the bubble flag to a no-bubble state indicator; the control system is further configured to: obtain the bubble flag based on a second frequency; trigger a bubble alarm message when the bubble flag is a bubble state indicator, and stop triggering the bubble alarm message when the bubble flag is a no-bubble state indicator for a third duration. In the present application, the bubble alarm message includes but is not limited to at least one of the following: an audible, visual, or visual alarm message emitted by the display screen of the console 21, an audible alarm message emitted by the sound module 218, or a remote alarm message emitted by a terminal device.

[0142] In the embodiment 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 status flag, and the bubble alarm task is to issue a corresponding alarm based on the bubble status flag. The bubble detection sensor is usually an ultrasonic sensor. Once the bubble passes through the bubble sensor, the bubble sensor can change the bubble status flag. 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 just flow into other locations and not be eliminated. The bubble may be ignored by the operator. Therefore, the bubble alarm task is to cancel the alarm after the bubble flag is in a no-bubble state for a certain period of time, thereby improving the safety of the bubble alarm. This time (the third duration) can be the time it takes for the bubble to circulate at least once in the pipeline.

[0143] Optionally, the first frequency can be set to 100 Hz, that is, the bubble detection task is performed once every 10 milliseconds; the second frequency can be set to 2 Hz, that is, the bubble alarm triggering task is performed once every 500 milliseconds.

[0144] Specifically, the pump system control module 40 reads data from a bubble sensor based on a first frequency (e.g., 100 Hz), which is used to detect bubbles in the flushing pipeline. During the execution of the bubble detection task, when the pump system control module 40 reads that the bubble sensor detects the presence of bubbles in the flushing pipeline, the pump system control module 40 sets the bubble flag to a bubble state flag; when the pump system control module 40 reads that the bubble sensor does not detect bubbles, and the second duration of no bubble detection reaches a second duration (e.g., 1 second), the pump system control module 40 sets the bubble flag to a no-bubble state flag. When executing the bubble alarm triggering task, the control system of the present application reads the bubble flag based on a second frequency (e.g., 2 Hz), triggers a bubble alarm message when the bubble flag is a bubble state flag, and stops triggering the bubble alarm message when the bubble flag is a no-bubble state for a third duration (e.g., 5 seconds). By configuring the bubble detection and bubble alarm functions, the operator is promptly and continuously reminded of bubbles entering the flushing pipeline, preventing bubbles from entering the target object.

[0145] Optionally, the pump system control module 40 is further configured to: obtain flushing pump operating data; and adjust at least one of the first frequency and the second frequency based on the flushing pump operating data. The flushing pump operating data includes, but is not limited to, flushing pump flow rate. Specifically, the bubble detection frequency can be dynamically adjusted based on the flow of the flushing fluid within the flushing pump. For example, by increasing the first frequency, smaller bubbles at higher flow rates can be detected. By dynamically adjusting the bubble detection frequency, detection accuracy is improved, missed bubble detection is avoided, and product safety is enhanced.

[0146] In some embodiments, the control device 2 is configured to: issue a bubble prompt message when the bubble alarm message is canceled, and the bubble prompt message is used to indicate that the control device 2 has issued an excessive bubble alarm to indicate that bubbles have appeared in the fluid channel corresponding to the blood pump 1.

[0147] 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 bubble alarm information can be canceled when the control device 2 stops triggering the bubble alarm information when the bubble flag is in the no-bubble state for a third time (for example, 5 seconds). At this time, the control device 2 can issue a prompt message to remind the operator that the control device 2 has issued a bubble alarm. The duration of the bubble alarm is limited, but the flushing pipeline connected to the outside of the blood pump is long, and there is also a flushing flow channel inside the blood pump. The bubbles may be trapped in a certain position in the pipeline or flow channel after passing through the bubble filter, but because they are trapped, they may not circulate again in a short time to the bubble filter to be detected. In the normal situation where the bubbles may still be eliminated, the bubble alarm cannot continue. Therefore, the bubble prompt information can remind the operator that bubbles have appeared in the recent period of time, which is convenient for the operator to check in time, eliminate the safety hazards of trapped but undiscovered bubbles, and improve safety.

[0148] In addition, the control device 2 can also accumulate and count the number of times the bubble alarm is issued to remind the operator that bubbles have appeared in the fluid channel corresponding to the blood pump 1, so as to prevent the operator from forgetting and improve the practicality and safety of the product.

[0149] In some embodiments, the blood pump 1 is an interventional pump, which includes an arterial pressure sensor. The interventional pump is connected to the control device 2 after the interventional pump is inserted into the target object's body. The control system is configured to: when the interventional pump is connected to the blood pump drive device 221, obtain arterial pressure data detected by the arterial pressure sensor; within the fourth time period when the arterial pressure data is detected, if the blood pump 1 is not started, an alarm message is triggered indicating that the interventional pump has not been running for a long time.

[0150] In this application, see Figure 2 As shown, the arterial pressure sensor can be arranged in the arterial pressure measurement path, which is formed by the gap between the intervention sheath and the driving catheter being connected to the arterial pressure measurement tube.

[0151] Specifically, the interventional process of the interventional pump is to push the interventional pump until it passes the arch and crosses the valve, withdraw the guide wire and tighten the proximal seal of the head, then fix the interventional sheath, and lock and reposition the sterile sleeve and the interventional sheath. After that, the arterial pressure measurement pipeline interface (outlet) of the interventional pump will be connected to the three-way valve of the interventional sheath side branch. At this time, the conditions for arterial pressure measurement are met, and blood flows in the gap between the interventional sheath and the catheter. The arterial pressure measurement pipeline interface is connected to the gap to form a fluid flow channel, and the blood pressure sensor on the other side of the arterial pressure measurement pipeline interface can therefore detect blood pressure. After the conditions for arterial pressure measurement are met, such as the arterial pressure measurement line interface of the interventional sheath and the drive catheter handle being connected, the interventional pump can be connected to the control device 2. For example, the second electrical connector 10P provided on one side of the interventional pump is plugged into the first electrical connector 20P provided on the other side of the control device 2. The specific steps are to put the interventional pump drive catheter handle into a sterile bag, place the drive motor and the blood pump drive device in the other end of the sterile bag, and then rush to the interventional pump drive catheter handle within the sterile bag, press the locks on both sides of the interventional pump drive catheter handle to connect it to the drive motor. After the interventional pump is connected to the control device 2, the control device 2 can obtain the arterial pressure data detected by the arterial pressure sensor. Under normal circumstances, during the operation process, the drive motor should be started after the interventional pump is connected to the control device 2 to drive the interventional pump to work. If the drive motor is not started for a long time after the interventional pump is connected to the control device 2, a noteworthy abnormality may have occurred. Therefore, if the blood pump 1 is not started within the fourth time period (for example, 2 minutes) of detecting arterial pressure data, an alarm message is triggered indicating that the interventional pump has not been running for a long time. By obtaining the duration of arterial pressure detection, an alarm prompt indicating that the interventional pump is not running is effectively triggered, which facilitates instructing operators to troubleshoot equipment errors or operational errors and improve equipment safety performance.

[0153] Based on the same inventive concepts as the above embodiments, embodiments of the present application also provide a method for detecting ventricular assist data, which is implemented based on the ventricular assist device provided in any of the above embodiments. The ventricular assist device includes at least a blood pump and a blood pump driver. In some embodiments, the ventricular assist data detection method of the present application can be implemented by a control module provided in the pump system.

[0154] The ventricular assist data detection method of the present application includes: obtaining blood pump sensor data and blood pump drive data corresponding to the blood pump, and determining the ventricular assist data corresponding to the blood pump based on the blood pump sensor data and / or blood pump drive data.

[0157] The bubble alarm method for the ventricular assist device of the present application further includes: acquiring flushing pump operating data; and adjusting at least one of the first frequency and the second frequency according to the flushing pump operating data.

[0158] Based on the same inventive concept as the above embodiments, an embodiment of the present application further provides a bubble alarm method for a ventricular assist device, which is implemented based on the ventricular assist device provided by any of the above embodiments.

[0159] The bubble alarm method of the present application includes: issuing a bubble prompt message when the bubble alarm message is canceled, wherein the bubble prompt message is used to indicate that the ventricular assist device has issued a bubble alarm, indicating that bubbles have appeared in the fluid channel corresponding to the ventricular assist device.

[0160] Based on the same inventive concepts as the above embodiments, embodiments of the present application further provide a method for detecting the presence of a blood pump in a ventricular assist device, which is implemented based on the ventricular assist device provided in any of the above embodiments. The ventricular assist device includes a blood pump, a blood pump driver, a blood pump monitoring module, and a motor monitoring module, wherein the blood pump monitoring module is disposed in the blood pump, the motor monitoring module is disposed in the blood pump driver, the blood pump driver and the blood pump are detachably connected, and the blood pump monitoring module and the motor monitoring module are detachably connected.

[0161] Figure 11 This is a flow chart of a method for detecting the presence of a blood pump in a ventricular assist device provided in an embodiment of the present application. Figure 11 As shown, the blood pump in-situ detection method includes the following steps:

[0162] S1: Acquire the communication signal between the motor monitoring module and the blood pump monitoring module.

[0163] S2: Determine a first duration of the communication signal in the first state.

[0164] See also Figure 8 As shown, the communication signal of the present application is the communication signal corresponding to the second communication pin pin2. Preferably, the communication signal is a communication transmission signal. The first state is a low level state.

[0165] S3: When the first duration reaches the first duration, outputting a prompt message that the blood pump is not connected to the blood pump driving device.

[0166] Optionally, the first duration may be set to 100 milliseconds.

[0167] Specifically, after the motor monitoring module and the blood pump monitoring module begin periodic communication, the signal state of the communication transmission signal is high and low, and the communication transmission signal is in a high-level state in the idle state. If the signal state of the detected communication transmission signal is a low-level state, and the first duration in the 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 transmission signal is a high-level state, or the first duration in the 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 combining the signal state and duration of the communication signal in the idle state of the serial port communication to perform in-place detection, it is possible to detect the blood pump in place in different scenarios such as when the blood pump is not connected, when the connection is complete, and when the connection is disconnected and then reconnected, without adding additional detection pins, simplifying the structure and making it easy to use.

[0168] Optionally, the ventricular assist device further includes a console, which is configured to output a prompt message indicating that the blood pump is not connected to the blood pump drive device.

[0169] Based on the same inventive concepts as the above embodiments, embodiments of the present application further provide a blood pump presence detection device for a ventricular assist device, which is implemented based on the ventricular assist device provided by any of the above embodiments. The ventricular assist device includes a blood pump, a blood pump driver, a blood pump monitoring module, and a motor monitoring module, wherein the blood pump monitoring module is disposed in the blood pump, and the motor monitoring module is disposed in the blood pump driver. The blood pump driver and the blood pump are detachably connected, and the blood pump monitoring module and the motor monitoring module are detachably connected.

[0170] The blood pump in-situ detection device is used for:

[0171] Acquiring a communication signal between the motor monitoring module and the blood pump monitoring module;

[0172] Determining a duration of the communication signal in the first state;

[0173] When the duration reaches a first duration, it is determined that the blood pump is disconnected from the blood pump drive.

[0174] In some embodiments, a blood pump presence detection device includes a first controller unit, a first electrical connector, a second electrical connector, a pull-up resistor, and a pull-down resistor;

[0175] Among them, the first electrical connector is provided in the motor monitoring module, and the second electrical connector is provided in the blood pump monitoring module;

[0176] The first communication pin of the second electrical connector is correspondingly connected to the second communication pin of the first electrical connector, and periodic serial communication is adopted between the first electrical connector and the second electrical connector;

[0177] The first communication pin is a communication transmitting pin, the first communication pin is connected to the power supply via a pull-up resistor, and the second communication pin is grounded via a pull-down resistor;

[0178] The first controller unit is connected to the second communication pin.

[0179] In some embodiments, the communication signal is a communication transmission signal, and the first state is a low level state; the first controller unit is configured to:

[0180] Obtain a communication transmission signal corresponding to the second communication pin; determine the duration of the communication transmission signal in the low-level state; and determine that the blood pump is not in place when the duration of the low-level state is greater than the first duration.

[0181] In the technical solution provided in the embodiment of the present application, when the blood pump is connected to the blood pump driving device, the motor monitoring module reuses the communication signal between the motor monitoring module and the blood pump monitoring module to perform blood pump presence detection. By judging whether the duration of the communication signal in the first state reaches the first duration, it can be judged whether the blood pump is in place, thereby issuing a prompt message. There is no need to set a dedicated presence detection pin on the blood pump and the blood pump driving device, which reduces the peripheral size of the blood pump and the blood pump driving device, making it easier for the operator to hold and use.

[0182] Based on the same inventive concepts as the above embodiments, embodiments of the present application also provide a method for alarming the operating status of a blood pump of a ventricular assist device, which is implemented based on the ventricular assist device provided by any of the above embodiments. The ventricular assist device includes a blood pump and a blood pump driver. The blood pump includes an arterial pressure sensor. The blood pump and the blood pump driver are connected after the blood pump is inserted into the body of a target subject.

[0183] Figure 12 This is a flow chart of a method for alarming the blood pump operation status of a ventricular assist device provided in an embodiment of the present application. Figure 12 As shown, the blood pump operation status alarm method includes:

[0184] S201: When the blood pump is connected to a blood pump driving device, arterial pressure data detected by an arterial pressure sensor is obtained.

[0185] S202: If the blood pump is not started within the target time period for detecting the arterial pressure data, an alarm message indicating that the blood pump has not been running for a long time is triggered.

[0186] Specifically, after the interventional pump is connected to the control device, arterial pressure data detected by the arterial pressure sensor is obtained. If the blood pump does not start within a fourth period (e.g., 2 minutes) of detecting arterial pressure data, an alarm message indicating that the interventional pump has not been running for a long time is triggered. By obtaining the arterial pressure detection time, an alarm message indicating that the interventional pump has not been running for a long time is effectively triggered, facilitating the troubleshooting of device errors or operational errors, and improving device safety.
