Therefore, the present application is intended to cover modifications and variations of the present application falling within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the present application can be combined with each other without contradiction.

[0048] Before describing the technical solutions provided by the embodiments of the present application, the problems existing in the related art will be specifically described to facilitate the understanding of the embodiments of the present application:

[0049] In actual use, the ventricular assist device generally adopts a mains power supply mode to provide working power for the ventricular assist device, but in the case of mains power failure, a backup battery power supply mode is used to maintain the operation of the ventricular assist device.

[0050] In the above related technology, in the case of using a backup battery power supply, since the backup battery needs to maintain the continuous operation of the ventricular assist device, the power consumption is large, and the backup battery power supply will affect the endurance time of the ventricular assist device.

[0051] To solve the problems existing in the above related technology, the embodiments of the present application provide a power supply control circuit.

[0052] Figure 1 The structure block diagram of the power supply control circuit provided by an embodiment of the present application is shown. As shown in Figure 1 The power supply control circuit can include:

[0053] At least one power supply switch module 10, the first end of the power supply switch module 10 is connected to the power supply of the ventricular assist device, the second end of the power supply switch module 10 is connected to the ventricular assist device, and the control end of the power supply switch module 10 is connected to the controller of the ventricular assist device.

[0054] In the embodiment, the first end of the power switch module is the input end of the power control circuit, and the second end of the power switch module is the output end of the power control circuit, that is, when the power switch module 10 is turned on, the voltage provided by the power supply can provide the working power supply for the ventricular assist device through the power switch module 10, so that the ventricular assist device can work normally.

[0055] In the embodiment, when the ventricular assist device needs to be powered, the controller outputs a control signal for turning on the power switch module 10, and at least one power switch module 10 is turned on according to the control signal, so that the ventricular assist device is connected to the power supply. When the ventricular assist device does not work or is in standby state, the controller of the ventricular assist device outputs an off control signal, and the power switch module 10 is turned off according to the off control signal, so as to cut off the connection between the ventricular assist device and the power supply. In the process of controlling the power supply to connect or disconnect the ventricular assist device, the power switch module 10 is controlled to be turned on or turned off according to the control signal, so as to reduce the power consumption of the ventricular assist device and prolong the use time of the ventricular assist device.

[0056] Referring to Figure 1 and Figure 2 In some embodiments, the power switch module 10 can include a first switch unit and a second switch unit. The control end of the first switch unit is connected to the control signal output end of the controller. The first end of the first switch unit is connected to the control end of the second switch unit. The second end of the first switch unit is connected to the ground end. The first end of the second switch unit is connected to the power supply. The second end of the second switch unit is connected to the ventricular assist device.

[0057] In the embodiment, the first switch unit can be used to control the second switch unit to be turned on or turned off according to the control signal provided by the controller, so as to receive the voltage provided by the power supply. The control signal output end of the controller can output a high-level signal for controlling the first switch unit to be turned on and a low-level signal for controlling the first switch unit to be turned off.

[0058] When the power control circuit works, the controller first outputs a turn-on signal to the first switch unit. The first switch unit is turned on according to the turn-on signal. At this time, the second switch unit detects that the first switch unit is turned on, and the second switch unit is turned on immediately, that is, the first end and the second end of the second switch unit are turned on, and the ventricular assist device is connected to the power supply. In this process, by controlling the turn-on or turn-off of the first switch unit, the turn-on or turn-off of the second switch unit is controlled, so that the power supply can be completely turned on or turned off. Especially when the ventricular assist device is in standby or non-working state, the power consumption of the ventricular assist device can be reduced, and the use time of the ventricular assist device can be prolonged.

[0059] In some embodiments, the power switch module 10 can output a 5V voltage as an example to introduce the power switch module 10.

[0060] Referring to Figure 2 , the first switch unit can include a fourth resistor R4, a tenth resistor R10, an eleventh resistor R11 and a fourth transistor Q3, the first end of the fourth resistor R4 is connected to the control signal output end of the controller, the second end of the fourth resistor R4 is connected to the base of the fourth transistor Q4 and the first end of the tenth resistor R10 respectively, the second end of the tenth resistor R10 and the emitter of the fourth transistor Q4 are both connected to the ground end, the collector of the fourth transistor Q4 is connected to the first end of the eleventh resistor R11, and the second end of the eleventh resistor R11 is connected to the control end of the second switch unit.

[0061] The second switch unit can include a first MOS tube Q1, a fifth resistor R5, a first capacitor C1, a fourteenth resistor R14 and a fourteenth capacitor C14, the gate of the first MOS tube Q1 is connected to the second end of the eleventh resistor R11, the source of the first MOS tube Q1 is connected to the first end of the first capacitor C1, the first end of the fifth resistor R5 and the power supply respectively, the second end of the first capacitor C1 and the second end of the fifth resistor R5 are connected to the second end of the eleventh resistor R11, and the drain of the first MOS tube Q1 is connected to the first end of the fourteenth resistor R14, the first end of the fourth capacitor C4 and the ventricular assist device respectively, the second end of the fourteenth resistor R14 and the second end of the fourth capacitor C4 are both connected to the ground end.

[0062] In the embodiments of the present application, the fourth transistor Q4 is an NPN type transistor, and the first MOS tube Q1 is a P-channel MOS tube as an example. When the controller outputs a high level signal, the base voltage of the fourth transistor Q4 rises, the emitter and collector of the fourth transistor Q3 are turned on, and the gate voltage of the first MOS tube Q1 is pulled down. At this time, the first MOS tube Q1 is turned on, the power supply is connected to the ventricular assist device, and the power supply outputs a 5V voltage through the second end of the power switch module 10 to provide power supply for the ventricular assist device.

[0063] Correspondingly, if the power switch module 10 is to be turned off, the controller outputs a low level signal, the base voltage of the fourth transistor Q4 is pulled down, the emitter and collector of the fourth transistor Q4 are cut off, at this time the fourth transistor Q4 is turned off, the gate voltage of the first MOS tube Q1 is raised, the first MOS tube Q1 is turned off, and the power supply is disconnected from the ventricular assist device.

[0064] In the case of controlling the conduction or turn-off of the first MOS tube Q1 to completely turn on or turn off the working power supply of the heart chamber auxiliary device, the conduction or turn-off of the first MOS tube Q1 can be controlled by controlling the conduction or turn-off of the fourth triode Q4, so as to control the conduction or turn-off of the first MOS tube Q1 to make the first MOS tube Q1 play the role of switch and isolation in the case of reducing power consumption, and the power supply can be more efficiently controlled to access the heart chamber auxiliary device to reduce the energy consumption of the heart chamber auxiliary device. At the same time, the fourth triode Q4 is used as the drive of the first MOS tube Q1, which can simplify the circuit design and reduce the complexity and cost of the circuit.

[0065] In the embodiment, the power supply can output 5V voltage through the power switch module 10 to provide power supply voltage for functional components in the heart chamber auxiliary device which need 5V voltage.

In the embodiment, the 12V voltage and the 24V voltage output by the power supply control circuit are configured according to the actual use demand, and the voltage output by the power supply control circuit can also be changed by changing the resistance value of the resistor at the second end of the power switch module 10, which is not limited here.

[0067] It is worth noting that the fourth triode Q4 in the first switch unit can be a triode, and the first MOS tube in the second switch unit can also be a triode, that is, the switch components in the first switch unit and the second switch unit can be triodes or MOS tubes, which are not limited here.

[0072] In the embodiment, the isolation power module 20 is used to convert the voltage provided by the power supply into an isolated power voltage.

[0073] In the process of working of the isolation power module 20, first, the isolation power module 20 accesses the second end output working voltage of the power switch module 10, the isolation power module 20 isolates the working voltage, outputs the corresponding isolated voltage of the working voltage through the output end of the isolation power module 20, and then inputs the isolated voltage into the ventricular assist device, which can reduce the risk of electric shock or other electrical safety, and enhance the safety guarantee of the patient.
