Description

Technical Field

[0001] The utility model relates to the technical field of power management for artificial assisted hearts, and particularly to a power management device for a peripherally implanted ventricular assist system. Background Art

[0002] A peripherally implanted ventricular assist device (PVAD) is a medical device implanted through peripheral blood vessels (such as the femoral artery or axillary artery) to assist the heart's pumping function. The core of such systems includes a blood pump, a controller, a power supply system, and connecting pipelines. Among them, the power supply system provides power support for the blood pump. Based on the easy availability of AC power, the absence of additional power conversion equipment, and the maturity of its power supply technology, AC power supply (AC power) is basically adopted at present. However, this power supply method has limited usage scenarios and is not convenient for working in mobile situations.

[0003] For example, when a patient needs to be transferred from one hospital to another, or from the emergency scene to the hospital, the PVAD system may need to remain operational to ensure the patient's hemodynamic stability. At this time, using AC power supply is no longer applicable. Therefore, how to improve the power supply management of the existing peripherally implanted ventricular assist system to make it applicable to a wider range of application scenarios has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0004] The utility model aims to solve the technical problems existing in the prior art, and provides a power management device for a peripherally implanted ventricular assist system, which can improve the application scenarios of the peripherally implanted ventricular assist system.

[0009] A power management device for a peripherally implanted ventricular assist system according to the present application includes a control unit, and the control unit includes a main control board and a control module which are electrically connected.

The control module is communicatively connected to the main control board on the one hand, and can feedback the signals collected by the control module to the main control board for unified scheduling by the main control board; on the other hand, the control module also provides power supply for the main control board. The control module is connected to an AC power supply unit and a DC power supply unit; a measurement component and a voltage conversion component are arranged on the control module, and the measurement component is electrically connected to the AC power supply unit and the DC power supply unit. During use, the power of the AC power supply unit or the DC power supply unit can be measured through the measurement component, and then it can be judged and selected to supply power through the AC power supply unit or the DC power supply unit.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0017] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0018] In this embodiment, a power management device for a peripherally implantable ventricular assist system, a power management device for a peripherally implantable ventricular assist system, includes a control unit. The control unit includes a main control board 120 and a control module 110 that are electrically connected. The control module 110 is connected to an AC power supply unit 130 and a DC power supply unit 140; a measurement component 111 and a voltage transformation component 112 are provided on the control module 110, and the measurement component 111 is electrically connected to the AC power supply unit 130 and the DC power supply unit 140.

[0019] In a specific implementation, a power management device for a peripherally implantable ventricular assist system includes a control unit. The control unit includes a main control board 120 and a control module 110 that are electrically connected. The main control board 120 serves as the command center of the system and is responsible for comprehensively regulating the operation of the peripherally implantable ventricular assist system. The control module 110 preferably uses an STM32 single-chip microcomputer, not only because of its powerful processing ability and flexible programming interface, but also because it can achieve efficient communication with the control main board.

[0020] The control module 110 is closely connected to the main control board 120 through the 485 communication protocol to ensure that various signals collected can be accurately fed back to the main control board 120, thereby realizing the unified scheduling and optimization management of the system. In addition, the control module 110 also shoulders the important task of providing a stable power supply for the main control board 120 to ensure the continuous and stable operation of the peripherally implantable ventricular assist system.

[0021] In terms of the power supply scheme, this device demonstrates extremely high flexibility and adaptability. It is equipped with both an AC power supply unit 130 and a DC power supply unit 140, providing diverse power supply options for various scenarios. The AC power supply unit 130 can be directly connected to the mains power, which is convenient and efficient. An AC-DC conversion circuit is also provided in the AC power supply module and the control module 110 to meet the demand for direct current of the control module 110. The DC power supply unit 140 usually selects a storage battery as the backup power supply to ensure the continuous operation of the percutaneously implantable ventricular assist system when the system needs to be moved or the mains power is unavailable.

[0022] The control module 110 also integrates a measurement component 111 and a voltage conversion component 112. The measurement component 111 is electrically connected to the AC power supply unit 130 and the DC power supply unit 140, and can monitor the power status of the AC power supply unit 130 or the DC power supply unit 140 in real time, providing data support for the system to intelligently select the optimal power supply scheme. The voltage conversion component 112 can be set at the power input end and / or the output end of the control module 110, and can flexibly adjust the voltage level of the power input end or the output end according to actual needs. For example, after converting alternating current into high-voltage direct current, it is then reduced to the low-voltage direct current suitable for the control module 110 via the voltage conversion component 112. At the same time, the control module 110 can also boost the voltage through the voltage conversion module to ensure stable and sufficient power supply to the main control board 120.

[0023] This scheme significantly broadens the power supply selection range of the percutaneously implantable ventricular assist system by introducing the DC power supply unit 140 and combining components such as the measurement component 111 and the voltage conversion component 112. It not only enhances the environmental adaptability and application flexibility of the system, but also provides reliable support for more complex and changeable medical scenarios, further promoting the clinical application and development of the percutaneously implantable ventricular assist system.

[0024] Furthermore, a charging circuit is provided between the control module 110 and the DC power supply unit 140 to improve the self-sufficiency ability of the system. When the measurement component 111 detects that the power of the DC power supply unit 140 is running low, the system will respond quickly and use the power of the AC power supply unit 130 to charge the DC power supply unit 140 in a timely manner to ensure that the DC power supply unit 140 can maintain a sufficient power reserve at any time and be ready for use.

[0025] Further, to make power management more intuitive and convenient, an acoustic / optical display device 113 is also integrated on the control module 110. This device includes a power-on indicator light, enabling users to clearly identify whether the percutaneously implantable ventricular assist system has been successfully powered on at a glance. A power supply unit indicator light can also be provided. This indicator light will intelligently emit lights of different colors according to the different currently selected power supply units. For example, it lights up blue when powered by alternating current and green when powered by direct current. Such an intuitive design makes the management of the power state simpler and faster.

[0026] Further, the control module 110 is also provided with a first direct current output port 114 to improve the expandability and practicability of the control module 110. Other components of the percutaneously implantable ventricular assist system can be powered through the first direct current output port 114. For example, the first direct current output port 114 can be selected to connect to a cooling fan to ensure that the system can maintain an ideal heat dissipation effect during long-term operation, thereby extending the overall service life; or connect to a motor control board to provide continuous power for the precise control of the system. In this way, the comprehensive performance and user experience of the percutaneously implantable ventricular assist system are further improved.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
