Title:
METHOD AND SYSTEM FOR AUTOMATICALLY SWITCHING POWER SUPPLY UPON POWER SUPPLY ABNORMALITY IN ECMO DEVICE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/217001
Kind Code:
A1
Abstract:
Provided is an ECMO device power supply method and system. An alternating-current power supply supplies power to a DC-DC buck-boost module (2) by means of an adapter (1). A power supply voltage is stabilized to a first preset voltage by means of the DC-DC buck-boost module (2). At the same time, the output end of the DC-DC buck-boost module (2) stabilizes the power supply voltage to a second preset voltage by means of a first voltage stabilizing module (3). The second preset voltage is used to supply power to an MCU (4). The MCU (4) is started. The MCU (4) controls a first MOS transistor switch (5). The first preset voltage is used to supply power to a motor (6) normally. According to the power supply method, the first MOS transistor switch (5) is controlled by the MCU (4) to achieve power supply switching control of an ECMO device by means of software, and the power supply method has characteristics such as high output precision, high efficiency, and reliable performance.
