[0020] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0022] Figure 1 is a schematic diagram of the structure of a ventricular assist system provided by an embodiment of the present application. Figure 1 The ventricular assist system 100 provided in the embodiment of the present application includes a blood pumping device 10 and a control device 30. The control device 30 includes a host 31 and a front-end controller 32, and the host 31 and the front-end controller 32 are independently distributed and connected to each other by telecommunications. The host 31 can provide a control interaction interface for the blood pumping device 10, as well as send control signals to the front-end controller 32 and receive data information fed back by the front-end controller 32. The front-end controller 32 is electrically connected to the blood pumping device 10, and can control the operation of the blood pumping device 10 according to the control signal it receives, and feed back data information of the blood pumping device 10 to the host 31.

[0023] The blood pumping device 10 can at least partially intervene in the target tissue to assist the heart in pumping blood. The target tissue can be the left ventricle of the human heart. The blood pumping device 10 can pump blood from the left ventricle of the human body and discharge it into the human artery, thereby reducing the workload of the natural heart and achieving the effect of assisting the ventricle. The blood pumping device 10 can generally include a blood pumping catheter, a blood pumping motor, and a transmission system connected between the blood pumping catheter and the blood pumping motor. The transmission system can transmit the power output by the blood pumping motor to the blood pumping catheter, driving the blood pumping catheter to achieve the blood pumping function.

[0024] The host 31 may be a removable device or a non-removable device having a control interface and integrated with a control mainboard. For example, the structure of the host 31 may be a tablet computer.

[0025] The front-end controller 32 may be a control box integrated with a control circuit board.

[0026] The front-end controller 32 and the blood pumping device 10 may be electrically connected via a cable or wirelessly.

[0027] The ventricular assist system 100 provided in the embodiment of the present application includes a blood pumping device 10 and a control device 30. The control device 30 includes a host 31 and a front-end controller 32 that are independently distributed and connected to each other by telecommunications. The host 31 is used to provide a control interaction interface, send control signals to the front-end controller 32, and receive data information fed back by the front-end controller 32. The front-end controller 32 is electrically connected to the blood pumping device 10, and is used to control the operation of the blood pumping device 10 according to the control signal received and to feed back data information to the host 31. That is, the ventricular assist system 100 provided in the embodiment of the present application separates the host 31 in the control device that is mainly used to provide a control interaction interface and generate control signals from the front-end controller 32 that is mainly used to drive and control the blood pumping device 10, which can save some heat dissipation components and / or signal shielding components, thereby effectively reducing the volume of the host 31 and the front-end controller 32.

[0028] In addition, the host 31 and the front-end controller 32 are independently distributed and connected by telecommunications. Under the premise of ensuring safe, reliable and convenient data transmission, the placement of the host 31 and the front-end controller 32 can be flexibly selected. For example, the front-end controller 32 directly connected to the blood pumping device 10 can be placed in a position adjacent to the blood pumping device 10, that is, a position adjacent to the patient, thereby shortening the length of the cable between the front-end controller 32 and the blood pumping device 10. At the same time, the host 31 can be placed in a position that is convenient for medical staff to operate, and even medical staff can move the host 31 at will within a certain range. It can be seen that the ventricular assist system 100 provided in the embodiment of the present application greatly improves the inconvenience of traditional medical staff having to operate next to the patient. The front-end controller can be flexibly placed next to the patient as needed according to actual conditions to shorten the length of the harness as much as possible. The embodiment of the present application improves the problem that the wiring harness around the bed is messy due to position restrictions, which affects or even interferes with medical staff in performing medical rescue work, and is not conducive to bed transfer.

[0029] Figure 2 yes Figure 1 Detailed structural diagram of the ventricular assist system shown in FIG. Figure 2 The host 31 includes a first wireless communication module 311, and the front-end controller 32 includes a second wireless communication module 321. The host 31 and the front-end controller 32 are wirelessly connected through the first wireless communication module 311 and the second wireless communication module 321, and perform data exchange.

[0030] The first wireless communication module 311 and the second wireless communication module 321 have a preset communication protocol to facilitate two-way communication between the two. The first wireless communication module 311 can send the control signal generated by the host 31 to the second wireless communication module 321, and can also receive the data information fed back by the front-end controller 32 through the second wireless communication module 321. The second wireless communication module 321 can receive the control signal sent by the host 31 through the first wireless communication module 311, and can also send data information to the first wireless communication module 311.

[0031] The first wireless communication module 311 and the second wireless communication module 321 provide a safe, reliable and convenient data transmission method for the host 31 and the front-end controller 32, and provide a basis for the host 31 and the front-end controller 32 to be separately and independently distributed within a certain distance range.

[0032] In some embodiments, the first wireless communication module 311 and the second wireless communication module 321 may each include a WiFi device and a BLE device.

[0033] The WiFi device and the BLE device can be integrated into one module. For example, the WiFi device and the BLE device can be a combined chip, which has rich pin resources, small size, and few antenna and structural design limitations.

[0034] The BLE network provided by the BLE device can feed back the real-time control information of the blood pumping device 10 and the perfusion device 20 obtained by the front-end controller to the host 31, so that the host 31 can store, analyze, process, and convert the information and display it on the control interface. The WiFi network provided by the WiFi device can upload various acquired data to the network information system for sharing or storage on the network information platform.

[0035] In some alternative embodiments, the first wireless communication module 311 and the second wireless communication module 321 may also include a transmitting antenna and a receiving antenna, which realize data exchange through waveform changes. This wireless propagation utilizes the principle of sending and receiving electromagnetic wave energy through antennas to realize the transmission of data information.

[0036] It is understandable that the first wireless communication module 311 and the second wireless communication module 321 can also be other devices or equipment that can realize data transmission function in a wireless manner, such as Bluetooth wireless communication module, Zigbee wireless communication module, etc., which will not be repeated here.

[0037] In some embodiments, the host 31 further includes a central processor 312 and a display 313, wherein the display 313 is used to provide a touch-type control interaction interface, and the display 313 is also used to display data information fed back by the front-end controller 32. The central processor 312 is electrically connected to the display 313 to generate a corresponding control signal according to the operation instruction received by the control interaction interface. The first wireless communication module 311 is electrically connected to the central processor 312 to wirelessly send the control signal to the second wireless communication module 321.

[0038] The display 313 has a touch screen, which can form a control interface, and the user can input operation instructions through the control interface. Specifically, the operation instruction can be the setting parameters of the blood pumping device 10 and the perfusion device 20, or the setting of other parameters of the ventricular assist system 100, etc. Exemplarily, the operation instruction can include the speed and current of the blood pumping motor of the blood pumping device 10, and can also include the speed and current of the perfusion motor of the perfusion device 20.

[0039] The touch screen of the display 313 can also directly display the data information fed back by the front-end controller 32. For example, the display 313 can also display real-time data such as the blood pumping flow rate of the blood pumping device 10, the perfusion flow rate of the perfusion device 20, and the real-time speed and current of the blood pumping motor, the real-time speed and current of the perfusion motor, etc.

[0040] After receiving the operation instruction, the central processing unit 312 may generate a corresponding control signal according to the operation instruction, and the control signal is sent to the front-end controller 32 through the first wireless communication module 311 .

[0041] The central processor 312 and the first wireless communication module 311 may be integrated on the same main control circuit board, and the central processor 312 and the display 313, as well as the central processor 312 and the first wireless communication module 311 may be electrically connected via wires.

[0042] The embodiment of the present application provides a central processing unit 312 and a display 313 with a display touch function, so that the structural integration is higher, the volume of the host 31 is reduced, and the convenience of placing, moving, and other operations of the host 31 is improved.

[0043] In some embodiments, reference Figure 2The central processor 312 may include a data processing unit 3121, and the first wireless communication module 311 is electrically connected to the data processing unit 3121. The data processing unit 3121 receives data information through the first wireless communication module 311, and the data processing unit 3121 also sends a control signal to the front-end controller 32 through the first wireless communication module. The data processing unit 3121 is electrically connected to the display 313 to parse and process the received data information to form corresponding processed data and send it to the display 313, and the display 313 is used to display the processed data.

[0044] The data processing unit 3121 can analyze and process the received data information to convert it into easily recognizable graphics or key data signals and send them to the display 313 for display. For example, the processed data displayed on the display 313 can be the current waveforms of the blood pumping motor 12 and the perfusion motor 22, as well as the waveform of the catheter position signal, etc.

[0045] Furthermore, the central processor 312 may also include a data storage unit 3122 , which is electrically connected to the data processing unit 3121 and is used to store data information received by the data processing unit 3121 and processed data formed after being processed by the data processing unit 3121 .

[0046] The data storage unit 3122 is also used to store various historical data and patient information of the blood pumping device 10 and the perfusion device 20.

[0047] In some embodiments, the ventricular assist system 100 includes a perfusion device 20, and the host 31 can also provide a control interface for the perfusion device 20. The front-end controller 32 is electrically connected to the perfusion device 20, and can control the operation of the perfusion device 20 according to the control signal it receives, and feed back data information of the perfusion device 20 to the host 31.

[0048] The perfusion device 20 is used to inject perfusion liquid, which generally includes a transmission pipeline, a perfusion motor, a perfusion liquid container and a waste liquid container. The transmission pipeline is used to intervene in the target tissue with the blood pumping device. The transmission pipeline is provided with an input flow channel and a discharge flow channel. The input flow channel and the discharge flow channel are connected to each other at the distal end of the transmission pipeline, and the input flow channel is connected to the human body fluid environment. The perfusion liquid container is connected to the proximal end of the transmission pipeline and is connected to the input flow channel. An input pump may be provided between the perfusion liquid container and the transmission pipeline, and the input pump can continuously pump the perfusion liquid in the perfusion liquid container into the input flow channel. The waste liquid container is connected to the proximal end of the transmission pipeline and is connected to the discharge flow channel. A discharge pump may be provided between the waste liquid container and the transmission pipeline, and the discharge pump can continuously pump the perfusion liquid in the discharge flow channel into the waste liquid container. The perfusion liquid can be, but is not limited to, a glucose heparin solution or a saline heparin solution. The perfusion motor is used to drive the input pump and the discharge pump to operate.

[0049] The perfusion device 20 is directly associated with the patient, just like the blood pumping device 10. In the present application, the perfusion device 20 is directly connected to the front-end controller 32, and the front-end controller 32 can be placed in a position adjacent to the blood pumping device 10 and the perfusion device 20, that is, in a position adjacent to the patient, thereby shortening the cable length between the front-end controller 32 and the perfusion device 20.

[0050] In some embodiments, the front-end controller 32 further includes a microprocessor 322, a blood pumping control module 323, and a perfusion control module 324, and the blood pumping control module 323 and the perfusion control module 324 are both electrically connected to the microprocessor 322. The microprocessor 322 is used to receive and parse the control signal, and distribute the sub-control signal generated by the parsing to the blood pumping control module 323 and / or the perfusion control module 324. The blood pumping control module 323 is electrically connected to the blood pumping device 10, and is used to control the operation of the blood pumping device 10 according to the sub-control signal distributed thereto. The perfusion control module 324 is electrically connected to the perfusion device 20 corresponding to the blood pumping device 10, and is used to control the operation of the perfusion device 20 according to the sub-control signal distributed thereto.

[0051] The perfusion device 20 corresponding to the blood pumping device 10 is connected to the blood pumping device 10, and is used to assist the blood pumping operation of the blood pumping device 10. Specifically, the blood pumping device 10 may include a blood pumping catheter and a transmission system connected to the blood pumping catheter, and the transmission system includes a rotating part and a fixed part, and the rotating part drives the blood pumping catheter to work. The perfusion device 20 is used to inject perfusion liquid, which generally includes a transmission pipeline, a perfusion motor, a perfusion liquid container, and a waste liquid container. The transmission pipeline is used to intervene in the target tissue along with the blood pumping device. The transmission pipeline is provided with an input flow channel and a discharge flow channel, and the rotating part may be provided in the discharge flow channel of the perfusion device 20.

[0052] The microprocessor 322 can be electrically connected to the second wireless communication module 321, and the second wireless communication module 321 sends the control signal received from the host 31 to the microprocessor 322. The microprocessor 322 identifies and analyzes the control signal and converts it into a sub-control signal that can be recognized by the blood pumping control module 323 and / or the perfusion control module 324. When the analyzed sub-control signal is related to the blood pumping device 10, the microprocessor 322 sends the sub-control signal to the blood pumping control module 323; when the analyzed sub-control signal is related to the perfusion device 20, the microprocessor 322 sends the sub-control signal to the perfusion control module 324.

[0053] The blood pumping control module 323 may be electrically connected to the controlled component and / or detection component in the blood pumping device 10 via a cable. Exemplarily, the controlled component in the blood pumping device 10 may be a blood pumping motor, and the blood pumping control module 323 may be electrically connected to the blood pumping motor via a cable, and is used to adjust the start and stop and speed of the blood pumping motor according to the sub-control signal it receives, thereby adjusting the blood pumping flow rate.

For example, the controlled component in the perfusion device 20 may be a perfusion motor, and the perfusion control module 324 may be electrically connected to the perfusion motor via a cable, and is used to adjust the start and stop and the speed of the perfusion motor according to the sub-control signal received, thereby adjusting the flow rate or flow velocity of the perfusion liquid.

[0055] The embodiment of the present application can independently control the blood pumping device 10 and the perfusion device 20 by setting a microprocessor 322, a blood pumping control module 323 and a perfusion control module 324 in the front-end controller 32, thereby avoiding mutual interference and influence between the operation of the blood pumping device 10 and the perfusion device 20. In addition, the microprocessor 322 itself has a certain processing capability, and can timely control the blood pumping device 10 and / or the perfusion device 20 to stop operating in the event of a fault or other special circumstances, thereby improving the reliability and safety of the ventricular assist system 100.
