Title:
CARDIAC PACING DEVICE, STORAGE MEDIUM, POWER SUPPLY DEVICE AND CONTROL METHOD FOR OUTPUT VOLTAGE
Document Type and Number:
WIPO Patent Application WO/2021/136545
Kind Code:
A1
Abstract:
A power supply device for an implantable medical instrument, a control method for the output voltage of the implantable medical instrument, a cardiac pacing device and a readable storage medium. The power supply device comprises a power supply module and a voltage adjustment module. The power supply module provides basic voltage. The voltage adjustment module comprises at least one capacitor array which can be connected to the power supply module, at least two switched capacitor units which can be connected in series or in parallel being arranged in the capacitor array; and the voltage adjustment module adjusts the output voltage of the power supply module to required voltage by utilizing the combination and connection modes of the switched capacitor units. The power supply device can select, according to the magnitude of the required voltage, different combination and connection modes of the switched capacitor units in the capacitor array to adjust the output voltage of the power supply module, is high in charge utilization efficiency, and facilitates the prolonging of the service life of the implantable medical instrument. The control method for the output voltage utilizes the power supply device, and the cardiac pacing device comprises the power supply device.
