Referring to fig. 3, fig. 3 is a schematic flowchart of a method for powering a ventricular assist device according to an embodiment of the present application, the method is applied to the external controller shown in fig. 1, fig. 2A, or fig. 2B, and the method includes steps S101 to S103:
in step S101, the external controller receives an external voltage input by an external power source.
The external Power source includes one or a combination of a battery and a Power source, where the Power source may be an adapter-based dc Power source (e.g., a household 220V Power source), a vehicle-mounted Power source, an Uninterruptible Power Supply (UPS) or the like.
In a possible example, as shown in fig. 1, when there is a single power supply path with the external power supply in the external controller, the receiving, by the external controller, the external voltage input by the external power supply includes: the external controller receives an input voltage of a one-way external power source, and takes the input voltage as the external voltage, wherein the external power source can be a battery or a power source.
In one possible example, as shown in fig. 2A or fig. 2B, when the external controller and the external power supply have multiple power supply paths, the receiving, by the external controller, the external voltage input by the external power supply includes: the external controller receives a first external voltage input by a first external power supply and receives a second external voltage input by a second external power supply, and the first external voltage and the second external voltage are integrated according to a preset rule to obtain a final external voltage.
Optionally, the integrating the first external voltage and the second external voltage according to a preset rule to obtain a final external voltage specifically includes: selecting any one of the first external voltage and the second external voltage as a final external voltage.
Optionally, the integrating the first external voltage and the second external voltage according to a preset rule to obtain a final external voltage specifically includes: and selecting the voltage value with the highest voltage value from the first external voltage and the second external voltage as a final external voltage.
Optionally, the integrating the first external voltage and the second external voltage according to a preset rule to obtain a final external voltage specifically includes: and judging whether the first external voltage and the second external voltage are smaller than a first voltage threshold value, if so, superposing the first external voltage and the second external voltage to obtain the final external voltage. According to the method, the voltage value of the external voltage is improved by superposing the voltages, the situation that the standby battery is frequently used due to the fact that the external voltage is too small frequently is avoided, the service life of the standby battery is shortened, and the standby battery is frequently replaced.
The first voltage threshold may be 5V, 10V, 15V or other values.
Of course, the application is not specifically limited to obtaining the final external voltage.
And S102, the external controller receives the internal voltage output by the standby battery in the external controller.
Optionally, the external controller obtains an internal voltage output by a backup battery of the external controller through a built-in sampling circuit, where the sampling circuit may be a voltage sampling circuit or a current sampling circuit, and a sampling process of the backup battery is prior art and will not be described in detail herein.
Step S103, the external controller judges the magnitude relation between the external voltage and the internal voltage, when the external voltage is greater than or equal to the internal voltage, the external voltage is adopted to supply power to the ventricular assist device, and when the external voltage is less than the internal voltage, the internal voltage is adopted to supply power to the ventricular assist device.
It can be seen that in the present example, a backup battery is preset in the external controller, and when the voltage of the external power supply is less than the voltage of the backup battery or the external power supply is abnormal, the backup battery is activated to supply power to the ventricular assist device, so as to maintain the stability of the operation of the ventricular assist device.
In a possible example, the method further comprises:
the external controller periodically detects the output voltage of the backup battery;
and when the output voltage is smaller than a first threshold value, the external controller starts a built-in charging circuit, and charges the standby battery according to the external voltage input by an external power supply based on the charging circuit.
The period of the periodicity may be 1 week, 2 weeks, or other values.
In the above possible examples, the external controller activating the built-in charging circuit specifically includes: when a charging circuit exists in the external controller, as shown in fig. 1, the standby battery is charged through the charging circuit; when there are two charging circuits in the external controller (i.e., there are multiple external power sources), as shown in fig. 2B or 2A, the backup battery is charged according to a preset charging rule.
Optionally, charging the backup battery according to a preset charging rule specifically includes: and starting the two paths of charging circuits and simultaneously charging the standby battery.
Optionally, charging the backup battery according to a preset charging rule specifically includes: and starting any one of the two charging circuits to charge the standby battery.
Optionally, charging the backup battery according to a preset charging rule specifically includes: and acquiring the voltage value of an external power supply connected with each charging circuit, starting the charging circuit corresponding to the maximum voltage value, and charging the standby battery.
Optionally, charging the backup battery according to a preset charging rule specifically includes: and judging whether the output voltage of the standby battery is smaller than a second voltage threshold value or not, if so, starting two charging circuits to charge the standby battery in a preset time period, detecting the output voltage of the standby battery in real time, and starting one charging circuit to charge the standby battery when the output voltage is larger than a third voltage threshold value. It can be seen that, in this example, when the voltage of the backup battery is too low, two charging circuits are used for charging simultaneously, so as to increase the charging speed, and when the backup battery is charged to a certain condition, in order to avoid heating during charging, only one charging circuit is used for charging the backup battery, so that the charging mode is increased.
The second voltage threshold may be 1V, 2V, 5V, or other values.
The third voltage threshold may be 7V, 10V, 15V, or other values.
Of course, the present application does not limit a specific charging method.
In a possible example, before the external controller determines the magnitude relationship between the external voltage and the internal voltage, the method further includes:
and the external controller judges whether the external voltage and the internal voltage are both smaller than a second threshold value, if so, the external voltage and the internal voltage are adopted to simultaneously supply power to the ventricular assist device, and if not, the operation of judging the magnitude relation of the external voltage and the internal voltage is executed. It can be seen that in this example, when both the external and internal voltages are too small, the voltages are superimposed as input voltages to maintain stability of the ventricular assist device operation.
In one possible example, the method comprises:
the external controller acquires battery parameters of the standby battery; the external controller determines the performance of the standby battery according to the battery parameters; and when the performance of the standby battery is determined not to meet the preset performance, the external controller sends prompt information to the user terminal, wherein the prompt information is used for prompting the replacement of the standby battery.
The performance parameter may be a voltage peak, a power supply duration, or other values.
It can be seen that in the present example, the performance parameters of the backup battery are detected in real time to avoid abnormal operation of the ventricular assist device due to insufficient battery performance, and to maintain the operating stability of the ventricular assist device.
